EXECUTIVE SUMMARY

PROJECT SETTING
The Villages of San Jacinto project site is approximately 475.1 acres in size and is located in the City of San Jacinto in northwestern Riverside County, California (see Figure 1-1, Regional Map). The project site is located in the northwestern portion of the City (see Figure 1-2, Vicinity Map). The project is located along Sanderson Avenue which is one of the City’s main northsouth transportation routes (see Figure 1-3, Site Location Map). The project site is bordered by undeveloped agricultural land to the north (and future westward extension of Ramona Boulevard), Sanderson Avenue to the east, Odel Avenue to the west, and undeveloped agricultural land and a municipal wastewater treatment plant to the south. The project site has been used as pasture land and/or a farming operation, similar to surrounding properties, for over one hundred years. The San Jacinto Valley has traditionally supported agriculture and rural residential land uses, but has been experiencing increased urbanization in the past several years.

The site is generally flat and is located on the alluvial plain of the San Jacinto River. The site elevation above sea level ranges from 1,455 feet along the northern edge to 1,490 feet in the southeastern corner. The southeastern corner of the site is a former cattle feed lot with several remaining animal shade structures. The remainder of the land consists primarily of vacant former agricultural land. Vegetation on site consists of weedy invasive species that have accumulated since the majority of agricultural production was discontinued. There are scattered sod fields in the northern portions of the property which is the only remaining agricultural operation. Several unnamed, unimproved dirt roadways traverse the site and are associated with former and current agricultural operations. Irrigation canals run along the edges of fields in support of sod farming activities. A detention basin is located along the north-central edge of the project site.

PROJECT DESCRIPTION
The project would consist of development of mostly vacant former agricultural lands into a suburban development including residential, commercial, mixed-use, public facility and open space/recreational uses. The 475.1-acre site would be divided into 18 "Planning Areas" (PA).

Each planning area would consist of a specific land use type with some having subareas of the particular land use. The following presents a summary of the proposed development while a detailed description is contained in Chapter 3 of this document.

Residential
Residential land uses would consist of 80.6 acres of low density and detached residential with 6,000-square-foot minimum lots and 117.9 acres of medium density residential having lot sizes

1.0 EXECUTIVE SUMMARY
Villages of San Jacinto EIR 4307-01

of 4,000 square feet and 5,000 square feet. The medium density residential development will have densities between 5.1 to 6.2 units per acre and a total of 657 dwelling units. Medium density residential is intermixed throughout the site and includes Planning Areas 1, 2, 4, 7, 8, 9, and 10. Low density uses would consist of single family residential lots with a density of approximately 4.5 dwelling units per acre, and a total of 359 dwelling units. The low-density development would be located in Planning Areas 3, 5, 6, 13, and 19. A total of 1,016 dwelling units are proposed with an allowance of up to 1,329 units if the proposed school site is not developed as discussed below.

Commercial
Commercial development would be focused in the southeast corner of the project site within PA

11. This development is intended to result in approximately 247,000 square feet of neighborhood retail commercial uses on 22.7 acres. This designation is intended to meet the provision for retail commercial land uses as set forth in the San Jacinto General Plan Land Use Element and to provide an accessible local shopping center for the proposed project and nearby communities.

This would allow for a wide range of businesses including grocery store, drug store, cleaners, restaurants, fast food, and specialty stores. The Specific Plan for the project includes Conceptual Design Guidelines and Development Standards for commercial development of this Planning Area. Comprehensive Design Guidelines will need to be reviewed and approved by the City prior to development of the Planning Area.

Mixed-Use
Mixed-use development will be provided within the 26.3-acre Planning Area 12. This designation is intended to provide for a broad range of land uses, with the primary focus on municipal uses such as library, police and fire facilities and other development such as business and professional park uses including dental and medical offices, real estate offices, banks, etc.

This area could also provide accessory uses to the primary facilities such as coffee shop, printers, postal/shipping outlets etc. This designation provides for a maximum of 343,000 square feet of building area and will have a maximum height limit of 45 feet. Conceptual Design Guidelines for commercial uses are provided in the project Specific Plan, but Comprehensive Design Guidelines will need to be reviewed and approved by the City prior to development of the Planning Area.

School
As noted in Table 3-2, Planning Area 14 is designated for a proposed high school by San Jacinto Unified School District (District). The 69.1 acre high school site would be located southwest of the future intersection of Cawston Avenue and Ramona Boulevard. Preliminary plans for the school include baseball and softball fields, a track/football stadium, gymnasium, performing arts facility and classroom space for up to 2,000 students. Final plans for the school would be processed separately from the Villages of San Jacinto Specific Plan through the District Board of Trustees and the California Division of the State Architect. If the District does not choose to construct a high school on this site, it will instead be used for residential uses. Under this scenario, Planning Area 14 would be developed with 200 low-density residences (minimum 6,000-square-foot lots) and 113 medium-density residences (5,000-square-foot lots). Because final planning for the school would be undertaken by the District, as its own lead agency under CEQA, this EIR’s impact analysis of the school is limited to a programmatic level.

Parks and Recreational Amenities
Following is a summary of the recreational amenities and park facilities planned for the proposed project. Further discussion of parks and recreation, including the requirement for provision of adequate parkland is contained in Section 5.12.4.

Public Parks
The proposed project includes three public parks totaling approximately 41 acres. The largest of the public parks is the 33.4-acre Community Park in Planning Area 15C north of Bridge Street in the southern portion of the proposed development. This park will provide soccer and baseball fields, concession area, as well as barbeque and picnic areas overlooking the proposed lake.

Public parks in Planning Areas 15B and 15D provide just over seven acres of various active and passive recreational opportunities.

Private Parks
The two private parks in Planning Areas 15A and 15E will provide passive recreation for nearby residents such as tot lots, shade structures, pathways and picnic areas.

Lake House and Swim Lagoon
Other recreational amenities include a 5.1-acre Lake House Beach Club and Swim Lagoon within Planning Area 16. This will be a private facility for residents and will feature a Swim Lagoon with sandy beach, play island, lap pool, play pool, fire pits, open turf area and shade

1.0 EXECUTIVE SUMMARY
Villages of San Jacinto EIR 4307-01
August 2009 1-10
structures. The clubhouse will provide an exercise room, activity room, restroom/changing rooms and office space.

Lake
The 11-acre private lake will be located primarily between Planning Areas 7 and 8 and adjacent to the Swim Lagoon. It will feature a concrete trail surrounding the lake and connecting to the community park in PA 15C. No swimming or boating will be allowed on the lake, but it will provide recycled water for irrigation of common landscaping within the community.

Paseos
A total of 9.6 acres of landscaped paseos will serve as pedestrian linkages between land uses and will create landscaped buffer areas between Planning Areas. These paseos will be a minimum of 50 feet wide and have 10-foot-wide concrete trails.

Open Space
In addition to the above parks and recreational amenities, approximately 15.2 acres of open grass-lined drainage channels/basins would be constructed along the western perimeter of the project site. A vegetated open detention basin will be located in the northwest corner of the project site. A total of 2.4 acres of landscape easements are provided in various locations throughout the project site. The proposed system of open spaces would provide both on-site and off-site visual benefits to compensate for the loss of existing open space character of the site.

Access
Roadway right-of-way would be located throughout the development and would provide access to and from as well as within the project. Sanderson Avenue and Odell Avenue would serve as primary access points for the project. Ramona Boulevard will be constructed to provide access along the north edge of the project site. Cawston Avenue would serve as the major north-south arterial through the project while De Anza Drive would serve as the major east–west arterial within the development taking access from Sanderson Avenue and connecting to Cawston Avenue. Modifications to Sanderson Avenue, Odell Avenue and Cawston Avenue would be required with project development. Improvements may include traffic light installation and additional turn lanes into the development from perimeter streets, where necessary. Secondary access to Planning Area 19 would be provided by the planned extension of Odell Avenue north to Ramona Expressway. The northern extent of Cawston Avenue would be terminated at the location of the proposed future alignment of Ramona Boulevard until this roadway is complete, at which time the dead ended Cawston Avenue would be retrofitted to form a functional intersection with Ramona Boulevard.

1.0 EXECUTIVE SUMMARY
Villages of San Jacinto EIR 4307-01
August 2009 1-11
Improvements to SR 79 within western Riverside County is currently being planned by Riverside County Transportation Commission (RCTC)/Caltrans within the general vicinity of the project.

Due to the conceptual nature of the ultimate alignment of the future SR 79 corridor, an on/off ramp into or near the proposed development is not contemplated as a project feature. Should roadway improvements be necessary to accommodate an ultimate SR 79 alignment, modifications to the project and preparation of a supplemental environmental document may be necessary. As of April 2004, the City has adopted a locally-preferred alignment for SR 79 which directs the roadway to the east of the proposed project. The Draft EIR/EIS for this project is expected to be circulated for public review in late 2009 with construction to begin in 2011. In late 2006, the City also selected a locally-preferred alignment for Mid-County Parkway, a future regional east-west roadway approximately 1,000 feet north of the project site which is a joint Caltrans/RCTC and Federal Highway Administration (FHWA) project. The 32- mile route will connect the San Jacinto area with the Corona area. Final environmental approvals are expected to be obtained by late 2010 to 2011 with construction set to begin sometime in 2013 (www.midcountyparkway.org).

Sewer and Water Service
The project would involve installation of an on-site sewer and water distribution system. Water and sewer service would be provided by Eastern Municipal Water District and be extended into the project via new conveyance facilities consistent with the District’s approved master plan expansion program. The project, along with other future development planning in the western portion of the City of San Jacinto, would contribute to the need for expansion of the Eastern Municipal Water District’s Hemet/San Jacinto Regional Water Reclamation Facility located to the south. The expansion of this facility is being analyzed by Eastern Municipal Water District (CEQA Lead Agency) in a separate environmental document.

Recycled Water Service. The project would utilize reclaimed water from the adjacent Eastern Municipal Water District Hemet/San Jacinto Regional Water Reclamation Facility. Recycled water would be utilized for lake/water features as well as common area irrigation needs throughout the proposed community. Recycled water would not be used for private landscaping such as front or back yards.

Storm Drain System
The project incorporates a drainage plan that will not impact upstream and downstream property owners but will provide flood protection for the overall project site. The Drainage Plan will incorporate a vegetative channel and a detention/water quality basin, which are designated as Line V and Detention Basin V. These two facilities are the major backbone infrastructure that will collect the runoff that emanates from off-site and on-site areas. Line V and Detention Basin

1.0 EXECUTIVE SUMMARY
Villages of San Jacinto EIR 4307-01
August 2009 1-12
V have been designed to convey and control the interim flow rate and ultimate flow rate. The interim flow rate results in a runoff rate that exceeds the ultimate condition flow rate. The interim condition will require the construction of two interim culvert facilities and the reconstruction of an earthen roadway to eliminate ponding east of DeAnza Drive and Sanderson Avenue intersection. These interim drainage facilities are required to control and convey the interim flow rates originating from the off-site area. Several storm drain laterals will provide flood protection for the on-site Planning Areas. Further details of the Drainage Plan are contained in Section 5.8, Water Quality and Hydrology.

Tentative Map
A draft tentative map (TM 36188) has also been prepared for the project. Figure 3-5, Tentative Tract Map, shows individual residential lots, mixed use and commercial areas and accessory uses including open space, lakes and roadways. In summary, the Tentative Tract Map, which further defines the Specific Plan Land Use Plan (described above), would allow the following housing units and other land uses to be developed on the project site:

Unit Type Summary
• 6,000-square-foot lots – 359 units
• 5,000-square-foot lots – 349 units
• 4,000-square-foot lots – 308 units

• 69.1-acre high school site
• 22.7 acres of commercial uses
• 26.3 acres of mixed-use
• 5.1-acre lake house and Swim Lagoon
• 43.0 acres for parks
• 11.0 acres for lake surfaces

Alternatives Summary
The following is a summary of the three (3) alternatives carried forward for analysis in this EIR.

The complete alternatives analysis is contained in Section 10.0 of this document. In addition to the CEQA-mandated consideration of a No Project scenario, two (2) alternatives were selected based on their ability to fulfill the basic objectives of the proposed project, as well as their capability to reduce any potentially significant adverse impacts of the project. A comparison summary of the alternatives is provided below, and impacts have been quantified wherever possible.
• Alternative 1: No Project/No Development Alternative
• Alternative 2: Existing General Plan Designation Alternative • Alternative 3: Reduced Density Alternative
No Project/No Development Alternative assumes that the project site would not be developed and the former agricultural operations (sod farm and cattle feeding area) would continue.

Existing General Plan Designation Alternative The existing General Plan designations establish 136.5 acres of low density residential and 239.5 acres of medium density residential. This would allow for a maximum of 2,390 medium density dwellings (10 du/ac maximum) and up to 682 low density dwellings (5 du/ac maximum) for a total of 3,072 dwelling units under the existing General Plan.

Reduced Density Alternative would involve the development of a low density housing tract with approximately 1-acre lots. Due to drainage and infrastructure needs, this alternative would consist of approximately 350 single-family homes (on approximately 350 acres), 41 acres of parks, 27 acres of greenbelts, 14 acres of drainage basin, 18 acres of lake surfaces, 18 acres of roadways and a 3-acre clubhouse. Due to the existing nature of the site topography, this project alternative would be prepared, graded and designed in a similar fashion as the proposed project.

Table 1-1, Alternatives Summary, provides a summary of alternatives as they compare to the proposed project. Each alternative was analyzed for its potential impact on environmental issues that were determined to be either significant and mitigable or significant and unmitigable in the proposed project condition. Issues such as land use and planning were not found to be significant, therefore analysis was not provided for each alternative.

Summary of Environmental Impacts
Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation Landform Alteration and Aesthetics

1. The project would introduce additional night
lighting within the project vicinity as well as potential new sources of glare (i.e., glass and reflective exterior surfaces). Particularly the commercial components of the site have the potential to produce significant night lighting impacts upon rural agriculture uses in the vicinity as well as proposed residential land uses within the project itself. Metal or other reflective exterior surfaces and finishes within the commercial components of the site could create new sources of light or glare resulting in significant glare impacts for adjacent residential, park, and agricultural uses.

5.2-a To avoid light and glare impacts, future submittals for commercial portions of the project development shall include a photometric lighting plan. The lighting plan shall demonstrate that project lighting is shielded from surrounding properties and that only the minimum amount of lighting required for safety purposes is provided to avoid adverse effects on surrounding areas. In general, lighting fixtures shall be shielded downward and away from the adjacent residential areas and public roadways. Commercial development plans shall also be reviewed to ensure the avoidance of substantial areas of reflective surfaces for building exteriors.

1. Incorporation of mitigation will reduce
impacts to below a level of significance.

2. Should Planning Area 14 be purchased by
the San Jacinto Unified School District for development as a high school, any potential light or glare impacts would need to be addressed by the School District in the course of their environmental compliance for that project. However, potential homebuyers in the vicinity should be made aware that potential outdoor lighting impacts may occur.

5.2-b A Notice-to-Property Owner shall be recorded on a separate buyer information sheet with the final map providing notice to potential future property owners in the vicinity of the school site (i.e., Planning Areas 1, 3 and 19) that there may be lighted ball fields in the future should the school district proceed with plans for the proposed high school.

2. Incorporation of mitigation will reduce
impacts to below a level of significance.

Agricultural Resources

1. Development of the proposed project would
potentially result in significant urban/rural land use conflicts between the planned residential development and existing agricultural uses surrounding the project site. Conflicts would potentially include fertilizer and pesticide application drift into the proposed residential area, residential

5.3-a A Notice-to-Property Owner shall be recorded on a separate buyer information sheet with the final map providing notice to potential future property owners of the proposed development that the property is located in an area of active agricultural land uses which may potentially result in inconvenience and/or discomfort associated with adjacent agricultural operations including noise, odors and dust generation, and chemical drift.

1. The proposed mitigation would serve to
alleviate land use conflicts associated with new residential development and existing agricultural land uses. However, this impact would remain significant and unavoidable until surrounding land converts to the ultimate planned uses prescribed under the City’s General Plan.

Villages of San Jacinto EIR 4307-01 August 2009 1-16
Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation complaints about noise and dust resulting from site preparation activities associated with adjacent agricultural uses, and increased trespassing onto agricultural lands.

2. The proposed project would irreversibly
convert land currently under agricultural production and identified as containing significant agricultural resources to urban uses and would contribute to incremental urbanization of a predominantly rural area sustaining existing agricultural land uses.

None. 2. The City’s General Plan EIR (January
2006) discusses a number of reasons mitigation for loss of agriculture is infeasible. Rising land costs to replace agricultural lands, rising water costs, labor costs, urbanization and environmental regulations all contribute to ongoing conversion of farmland. Without property owner cooperation and substantial financial incentives, it is infeasible to provide permanent on or offsite mitigation to replace converted farmland. Therefore, no feasible mitigation measures are available to reduce this impact below a level of significance.

Biological Resources

1. Sensitive vegetation communities on the
Villages of San Jacinto Project site include 4.22 acres of open water, 0.23 acre of freshwater marsh, 0.07 acre of southern willow woodland, 0.21 acre of herbaceous wetlands, 0.01 acre of cismontane alkali marsh, and 0.01 acre of intermittent unvegetated stream channel. These areas are under the jurisdiction of RWQCB and/or CDFG. All impacts to RWQCB/CDFG jurisdictional areas are considered significant.

5.4-a Mitigation for impacts to jurisdictional wetlands and nonwetlands waters will consist of: (1) off-site creation, (2) a combination of off-site creation and enhancement of wetlands of equal or higher habitat quality, or (3) purchase of wetlands mitigation credits in an approved mitigation bank. Because wetlands/waters on the Villages of San Jacinto project site are isolated, of low overall quality (contain large quantities of nonnative species), and are surrounded by agricultural lands, they do not provide high quality habitat for riparian-dependent wildlife species, therefore mitigation onsite would not result in equal or greater wetland habitat value. Mitigation for on-site wetlands/waters impacts would be a biologically equivalent or superior alternative to avoidance of these impacts. The above not withstanding, wetlands areas created, enhanced, or preserved through the project’s wetlands mitigation plan would

incorporation of mitigation will reduce impacts to below a level of significance.

Wetland mitigation ratios are based on past experience developing appropriate mitigation for impacts to similar wetland and/or Waters of the US.

Herbaceous Wetlands, Open Water, Freshwater Marsh and Intermittent Stream Channel Mitigation for impacts to 4.22 acres of open water, 0.23 acre of freshwater marsh, 0.21 acre of herbaceous wetlands, and 0.01 acre of intermittent unvegetated stream channel would be accomplished through creation or purchase of wetlands mitigation credits from an approved mitigation bank at a 1:1 ratio (i.e., 4.67 acres total). (see Section 5.4 in the EIR), Cismontane Alkali Marsh Mitigation for impacts to 0.01 acre of cismontane alkali marsh would be accomplished through the creation, or a combination of creation and enhancement, of wetlands of equal or higher habitat quality at a 3:1 ratio (i.e., 0.03 acre). Mitigation can also be accomplished through the purchase of wetlands mitigation credits in an approved mitigation bank.

Southern Willow Woodland
Mitigation for impacts to 0.07 acre of southern willow
woodland would be required at a ratio of 4:1 (i.e., 0.28 acre) (see Section 5.4 in the EIR). Mitigation can be accomplished through the creation, or a combination of creation and enhancement of wetlands of equal or higher habitat quality. Mitigation can also be accomplished through the purchase of wetland mitigation credits in an approved mitigation bank.

2. Impacts to the burrowing owl are covered in
accordance with the Species Conservation Objectives for the burrowing owl listed in the MSHCP. That said, in order to comply with the specific Burrowing Owl Survey Area provisions of the MSHCP, mitigation for direct impacts to known individuals will require mitigation.

5.4-b Per MSHCP, because of the site does not support long term conservation value for burrowing owls , mitigation for impacts to this pair of owls can include passive or active relocation of owls following accepted protocols per the burrowing owl Species Account in Volume II-B of the MSHCP. In addition, MSHCP requires that: "Pre-construction presence/absence surveys for burrowing owl within the survey area where suitable habitat is present will be conducted for all Covered Activities through the life of the permit. Surveys will be conducted within 30 days prior to disturbance. Take of active nests will be avoided. Passive relocation (use of one way doors and collapse of burrows) will occur when owls are present outside the nesting season." Because impacts to other sensitive wildlife species are covered under the MSHCP, no additional mitigation is proposed for impacts to these species. However, if construction activity is to take place during the breeding season (i.e., January through October), a one-time biological survey for nesting bird species would be conducted within the proposed impact area no earlier than 72 hours prior to construction. This survey is necessary to assure avoidance of impacts to nesting native birds (per the federal Migratory Bird Treaty Act). If nesting birds are detected within vegetation which is to be impacted, the nest location(s) will be protected. A buffer of 25 to 300 feet (specific width to be determined by the project biologist according to species of bird) around the nest will be avoided until fledging.

5.4-c MSHCP requires that night lighting shall be directed away from the MSHCP conservation area. Shielding will be incorporated by the project to ensure that ambient lighting in the MSHCP conservation area is not increased; therefore impacts on potential adjacent MSHCP conservation area lands due to increased lighting would be avoided.

2. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

3. Due to the project’s location adjacent to land
that could potentially be conserved through the MSHCP Plan, potential indirect impacts related to invasive species may occur.

5.4-d Table 6.2 of the MSHCP lists landscape plant species that shall be avoided for all portions of developments that are located adjacent to (within 1,000 feet) the MSHCP conservation areas. These plant species will be avoided on the areas of the Villages of San Jacinto project site adjacent to Criteria Cells 2775 and 2878 to the west of the project site. This would be achieved by including language in the residential sale documents to ensure that future property owners understand the types of plants that are restricted. Sample language for inclusion in sale documents would be submitted to the Planning Department for approval prior to approval of a certificate of occupancy. Therefore no indirect effects due to invasive species are anticipated.

3. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

Cultural Resources

1. Due to the presence of five previously
recorded sites located within one mile of the project and the fact that the project is located within an alluvial setting, potentially significant archeological resources could be unearthed during site grading.

5.5-a In order to reduce the potential for disturbance or damage to unknown archaeological resources, monitoring of mass grading activities of the site during . by a qualified archaeologist is required. Should the monitor observe disturbance of resources that could be important archaeological artifacts, the monitor shall have the power to stop grading in the immediate area of discovery in order to allow for a resource study and recovery/curation effort (if necessary) to occur.

1. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

Geology and Soils

1. Many portions of the site are characterized
as having unsuitable compressible soils not suitable for structural support. Location of a structure on an unstable geological unit or soil would be a significant impact.

5.6-a The on-site soils are suitable for reuse as compacted fill, provided they are relatively free of organic materials, debris and oversize materials. The optimum lift thickness to produce a uniformly compacted fill will depend on the type and size of compaction equipment used. In general, fill will be placed in uniform lifts not exceeding 8 inches in thickness. Fill soils will be placed and compacted to a minimum 92% relative compaction at a minimum of 2% above the optimum moisture content.

1. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

Villages of San Jacinto EIR 4307-01 August 2009 1-20
Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation Fill slopes shall be overbuilt a minimum of 2 feet and trimmed back to the compacted core or rolled with a weighted sheepsfoot compaction roller as the fill slope height increases in maximum 4-foot increments. Placement and compaction of fill shall be performed in accordance with City grading ordinances and minimum compacted standard under the observation and testing of a qualified geotechnical engineer.

All loosely packed exploration trench backfill shall be removed and recompacted in accordance with project geotechnical guidelines. An engineering geologist shall be present to observe all excavations to confirm limits of faulting. If exposures differ from anticipated conditions, further investigations and/or additional structural setbacks can be required.

2. The perched groundwater table may be
located between 5 and 22 feet. A shallow groundwater table can present hazards during site development.

5.6-b. To facilitate the grading operations, on-site irrigation water shall be reduced or ceased for a period of 3 to 6 months prior to the start of grading. Further, the contractor will pothole the upper 12 to 14 feet of soil prior to the start of grading operations to determine if shallow groundwater will affect the planned grading.

In localized areas where shallow groundwater conditions exist such that removals cannot be performed to the required depths or where deeper excavations (such as in the proposed "lake" areas) are proposed at or below the existing perched groundwater, methods of localized dewatering will be required including the use of well points and/or interceptor ditch methods. Alternative ground stabilization methods such as deep dynamic compaction shall be required. Deep dynamic compaction is a means of physically compacting the subsurface soils by repeatedly dropping a heavy weight (typically a large concrete block) to densify the underlying soils to a predetermined density. After proposed grading plans are developed, these areas shall be further reviewed by a qualified geotechnical engineer.

incorporation of mitigation will reduce impacts to below a level of significance.

3. Potential site ground rupture, as determined
by the Leighton and Associates Fault Investigation, is considered moderate to high. Ground rupture due to on-site faults could potentially affect existing and future facilities (such as gas, electrical, water mains, etc.) that traverse fault zones on the site. Secondary seismic effects due to strong ground shaking, ground rupture, liquefaction and seismically induced settlement are considered significant.

5.6-c. A structural setback zone of 50 feet on either side of the encountered fault zone, and as much as 75 feet on the "downblock" side shall be observed for structures intended for human occupancy (2,000 hours/year). This preliminary setback zone will be refined as the grading concept is developed and possible additional site studies are performed. The Fault Location Map (Plate 2) within the Fault Investigation shows required preliminary structural setbacks. However, the final setback limits shall be determined during grading or future studies as the fault trace is exposed, identified and surveyed for lateral and vertical location. The setbacks shall be shown on all project plans. To reduce the effects and magnitude of the earthquakeinduced settlements, remedial grading shall occur. Following remedial grading, differential dynamic settlements are anticipated to be approximately 2 inches in a horizontal distance of 40 feet. Additional analysis will be performed by a qualified geotechnical specialist to further refine earthquakeinduced settlement. Based on a review of the rough grading plans by a qualified geotechnical specialist, remedial grading requirements will be revised. To reduce the potential adverse secondary seismic effects, mitigation of compressible alluvial soils to support the planned development at areas such as free-face slopes ("green belt" detention basins, channels etc.), the project perimeter (where removals may be limited by property restraints) and planned lake areas will require additional geotechnical stability design by a qualified geotechnical engineer after project plans are developed.

3. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

4. The volume change of excavated on-site
materials upon recompaction is expected to vary with materials, density, insitu moisture content, location and intended compaction effort. Therefore, it is likely that on-site ground rupture could potentially affect future

5.6-d. While it is difficult to determine the level of subsidence and shrinkage risk, site grading must include a balance area or ability to adjust import quantities to accommodate some variation. Relative compaction rates must be followed as they appear in the February 28, 2005, Leighton and Associates Technical Report. As stated in the February 28, 2005,

Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation site improvements. Based on the site specific fault investigation, the potential for site ground rupture during a seismic event is considered moderate to high.

Leighton Report, due to the agricultural discing of the surface soils, a subsidence value of 0.2 feet must be applied when evaluating earthwork volumes.

5. The relatively loose saturated alluvial
deposits on site are considered susceptible to liquefaction hazards.

5.6-e. To reduce the potential for liquefaction and earthquakeinduced settlements at the site, the following guidelines will be implemented. For preliminary design purposes, a minimum removal and recompaction of 10 feet (as measured from finish grade) will be used in cut areas on that portion of the site designated as having a high potential for liquefaction (roughly the northern one third to one half of the site). In cut areas outside the area designated as high potential for liquefaction, a minimum overexcavation of 5 feet below finish grade must be used. For areas designated as "fill" a minimum removal of 5 feet will be used, provided a minimum total thickness of 10 feet of properly compacted fill is maintained below the lowest adjacent finish grade (including lowest adjacent street elevation). The removal depths for the infrastructure roadways shall be a minimum 5 feet below pavement subgrade. These estimates are for preliminary design planning only and will be revised based on our review of rough grading plans. These preliminary estimates will be revised upon review of the proposed grading concept plan. These alluvial soils must be removed down to medium dense to dense, relatively non-porous alluvium material as determined by the geotechnical consultant. Undercuts will be made 1:1 next to existing roadways that will remain after grading. Cut slopes shall be replaced as properly compacted fill. The excavated materials will be moisture conditioned or dried back, as appropriate, to achieve the required minimum relative compaction. Saturated soils may need to be dried back or mixed with drier on-site materials and shall be thoroughly mixed prior to fill placement. The resultant excavation will be filled and compacted in this lifts to a minimum 92% relative

Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation compaction at a minimum of 2% above the optimum moisture content. A minimum 90% relative compaction may be acceptable in the southern portion of the site. This will be determined during review of rough grading plans.

After completion of the required removal of unsuitable soils, the approved surface will be scarified, moisture conditioned as needed and compacted prior to placing fill. If subgrade conditions at the approved bottoms are wet and "pumping" near the required removal depth, the scarification and moisture conditioning will not be necessary. Stabilization measures where shallow groundwater conditions are expected at or near the required removal depth may include the use of a stabilization fabric and/or coarse gravel/graded rock and gravel. Where shallow groundwater conditions are present, alternative ground improvement guidelines shall be followed (see Mitigation Measure 5.5-b). Further evaluation of these specific areas will be necessary after draft grading plans are prepared.

6. Manufactured slopes that are planned for
construction on the site would be susceptible to slope stability hazards. Slopes adjacent to severe flow direction changes may be susceptible to increases scour erosion and slope stability.

5.6-f. All slopes will be provided with appropriate surface drainage features and landscaped with drought-tolerant, slopestabilizing vegetation as soon as possible after grading to reduce the potential for erosion. Berms will be provided at the top of fill slopes to direct water away from slope faces. Lot drainage shall be directed such that runoff on slope faces is minimized. Oversteepening of slopes must be avoided during fine grading and building construction. Although not anticipated, if seepage is encountered in slopes, special drainage features may be necessary.

5.6-g. For slopes that are will be adjacent to ditches or other water conveyance features, proper protection including rip rap or other slope protection devices as designed by the project civil engineer would be required. Slope stability and the potential for scour shall be required in the design drainage alignment.

Topic / Impacts Mitigation Measures / Design Features Level of Significance after Mitigation Paleontological Resources

1. Since the proposed project lies within a
geologic formation with high resource bearing potential and the project would necessitate recompaction of potential fossil bearing alluvium, impacts to paleontological resources are considered to be significant. Impacts to paleontological resources could occur during excavation and site development when geologic formations that have resource bearing potential are disturbed. Impacts would occur when fossils are physically destroyed by such activities.

5.7-a. Prior to beginning any excavation work, the developer or its contractor shall demonstrate that a qualified paleontologist has been retained to carry out a paleontological resources mitigation program. A paleontological monitor shall be on site at all times during grading activities that disturb nonundocumented fill soils or formations. If fossils are discovered, the paleontologist or paleontological monitor shall have the authority to halt construction in the immediate area of discovery until such a time that a complete assessment of the resources can be conducted. If resources are found that are determined to be significant, the paleontological monitor shall direct activities to recover the resources. Prepared fossils, along with copies of all pertinent field notes, photos and maps shall be deposited in a scientific institution with paleontological collections, such as the San Bernardino County Museum.

1. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

Water Quality and Hydrology

1. Implementation of the project would increase
the amount of impervious surfaces within the local area which would result in increased runoff and reduced on-site water percolation. Increasing an area’s impervious surface may result in drainage problems and flooding.

5.8-a. The project is located within the San Jacinto – Area Drainage Plan (SJ-ADP), which is a financing mechanism used to offset costs for construction of proposed Master Drainage Plan (MDP) facilities. The project will be charged a per-acre fee in order to pay a fair share of the price of area-wide drainage facilities.

1. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

2. All lake and drainage features on site would
be constructed so they are above the groundwater table so as to prevent intermixing of ground and surface waters. That said, it is possible that during project construction, groundwater may be encountered.

5.8-b. If dewatering becomes necessary during construction, all discharges shall be in accordance with Santa Ana Regional Water Quality Control Board requirements which mandate that dewatered groundwater be tanked and hauled to a legal disposal site for treatment. Dewatering shall not occur in onsite drainages or water features. In addition, if dewatering becomes necessary during construction, a National Pollution Discharge Elimination System dewatering permit shall be obtained from the Santa Ana Regional Water Quality Control Board.

2. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

3. The northern portion of the project site is
located within the 100-year floodplain of the San Jacinto River. Development within the floodplain would result in an impedence to flow and an increase in the base flood elevation. Because a portion of the proposed development is proposed to be constructed within the limits of the 100-year floodplain, development of the proposed project will result in potentially significant impacts relating to flood hazards.

5.8-c. All buildings shall be located outside of the 100-year floodplain.

The applicant shall process a Flood Insurance Rate Map (FIRM) map revision. Further, the applicant shall obtain a Conditional Letter of Map Revision (CLOMR) prior to issuance of building permits. The project applicant, or subsequent property owners, shall obtain flood insurance, to the extent required by law, to protect against any damage that might occur during a flood event. It must be noted that at the time of EIR publication, the applicant and City had initiated the CLOMR process with the Riverside County Flood Control and Water Conservation District.

3. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

4. Development of the proposed project may
result in an increase in pollutant load due to sedimentation. Sediments are soils or other surficial materials eroded and then transported or deposited by the action of wind, water or gravity. Sediment from erosion, primarily during construction, is quite often a major project pollutant of concern. A potentially significant impact could occur during construction related to sedimentation.

5.8-d. During construction, the project will incorporate all City of San Jacinto construction Best Management Practices (BMPs). These BMPs include the following:
• Erosion control BMPs including temporary seeding,
permanent seeding, etc.
• Soil stabilization BMPs • Sediment control BMPs including silt fence perimeter controls, surface roughening, tree or natural vegetation preservation and protection, temporary gravel construction entrance/exit, temporary diversions, permanent diversions, outlet stabilization, inlet protection, temporary sediment basins and gravel bay barriers. • Wind erosion BMPs • Minimize contact with Stormwater BMPs including BMPs for construction vehicles and equipment maintenance, fueling and washing, materials maintenance and construction material loading, unloading and access area controls. • Non-storm water BMPs • Post-construction BMPs

5.8-e. The project applicant will need to develop a Stormwater Pollution Prevention Plan (SWPPP) pursuant to NPDES Storm Water Discharge Associated with Construction Activity Guidelines (Water Quality Order 99-08-DWQ). The SWPPP will identify all BMPs that will prevent construction pollutants from contacting storm water. Measures shall also be designed so as to prevent all products of erosion from moving off site into receiving waters. Provisions will also be included to ensure that BMPs are monitored and success recorded.

5. Development of the proposed project may
result in an increase in pollutant load due to sedimentation. Sediments are soils or other surficial materials eroded and then transported or deposited by the action of wind, water or gravity. Sediment from erosion, primarily during construction, is quite often a major project pollutant of concern. A potentially significant impact could occur during construction related to sedimentation.

5.8-f. Structural Best Management Practices (BMPs) are required for new development to improve water quality of stormwater runoff. In order to meet NPDES regulations, the design volume or design flow to be treated must reduce pollutants to the Maximum Extend Practicable (MEP). This project will incorporate a water quality extended detention basin to provide water quality treatment for the runoff emanating from the project site, a volume-based BMP, and a flow-based BMP. Once the project is complete, maintenance will be the responsibility of the Villages of San Jacinto homeowners association. In addition to sizing techniques, several quantity-control Best Management Practices (BMPs) shall be implemented to control runoff:
• Rainfall shutoff devices shall be used to prevent irrigation during and after precipitation;
• Irrigation systems shall utilize a dripping system to eliminate nuisance run-off; and
• Backflow preventer/pressure regulators shall be installed. • The project applicant will need to develop a Water Quality Management Plan pursuant to NPDES Permit #CAS 618033, order # R8-2002-001. The Water Quality Management Plan will identify all final site BMP requirements.

• Install energy dissipaters at the outlets of new storm drains that enter the regional storm drain system that eventually feeds into the San Jacinto River. • Utilize and install "high to medium efficiency" Post
Construction BMP filtration system within the proposed water quality basin that would help reduce as many bacteria and viruses as possible from entering the downstream local stormwater collection system. This system must follow the specifications of the California Stormwater Handbook to ensure that the system provides maximum bacteria/viral capture.

2. Intersections are projected to operate at
unacceptable LOS E or F during the peak hours without improvements. Some required improvements would exceed the General Plan typical roadway cross sections and are therefore not feasible. Improvements in excess of the ultimate planned roadway cross-sections at the study intersections would not be required to achieve acceptable LOS for cumulative conditions with completion of the MCP and SR 79 projects. However, it should be noted that completion of these regional improvements can’t be determined by the City.

5.9-e Because the project, along with many others in the area, is contributing to the city-wide need for street improvements, the project will need to contribute to the Riverside County TUMF and City of San Jacinto DIF programs. As discussed in Section 5.9.2, these fees are collected as part of a funding mechanism aimed at ensuring that local and regional highway capacity keeps pace with projected growth throughout the area. Eligible facilities for funding by the City’s DIF program are identified on the City’s Facility Needs List, which currently extends through the year 2020. Table 5.9-17, Estimated TUMF and DIF Fee Calculations, includes estimated fee calculations for the proposed project based on current fee rates. Many off-site circulation improvements required as a result of project impacts would be mitigated through participation in the TUMF fee program. Many of the off-site improvements that are needed will be planned, designed and constructed by the City, Riverside County Transportation Department, Riverside County Transportation Commission, other cities or a combination of the above.

In order to ensure that all off-site traffic improvements are constructed by the City (or the County/RCTC), prior to construction of specific project phases, the City shall ensure that the improvements are made to compensate for the project's contribution to off-site circulation issues. The project applicant's payment of TUMF and DIF fees will allow the financing mechanism to conduct such improvements.

2. The project would contribute to a significant
unavoidable impact for cumulative traffic conditions if the MCP and SR 79 projects are not in place upon completion of the first phase of project development. Because the City can not guarantee that these regional facilities would be in place prior to project build-out, a significant, cumulative impact to regional traffic may occur in the absence of these facilities.

3. The additional worker and constructionrelated truck trips to and from the project site would potentially affect traffic operations at project area intersections during peak hours.

5.9-f The contractor for each phase of the project shall be required to prepare and implement a traffic control plan (TCP) in order to monitor construction equipment, deliveries and construction worker traffic to eliminate any potential hazards to surrounding roadways due to abnormally high traffic into or out of the site

3. Incorporation of mitigation will reduce
impacts to below a level of significance.

Air Quality

1. The maximum construction-generated PM10
emissions of 36.58 pounds per day would be below the SCAQMD’s quantitative significance threshold of 150 pounds per day. Although such fugitive dust would be short term and would only last during the duration of grading activity, such emissions could cause a public nuisance or further exacerbate the existing PM10 nonattainment situation in the SCAB.

5.10-a Consistent with SCAQMD Rule 403, it is required that fugitive dust generated by grading and construction activities be kept to a minimum with a goal of retaining dust on the site, by following the dust control measures listed below: a) During clearing, grading, earth moving, excavation, or transportation of cut or fill materials, water trucks or sprinkler systems shall be used to prevent dust from leaving the site and to create a crust after each day’s activities cease. b) During construction, water truck or sprinkler systems shall be used to keep all areas of vehicle movement damp enough to prevent dust from leaving the site. At a minimum, this would include wetting down such areas later in the morning and after work is completed for the day and whenever winds exceed 15 miles per hour. c) Soil stockpiled for more than two days shall be covered, kept moist, or treated with soil binders to prevent dust generation. d) Reduce speeds on unpaved roads to less than 15 miles per hours.
e) Halt all grading and excavation operations when wind speeds exceed 25 miles per hour.
f) Dirt and debris spilled onto paved surfaces at the project site and on the adjacent roadways shall be swept, vacuumed, and/ or washed at the end of each workday. g) Should minor import/ export of soil materials be required, all trucks hauling dirt, sand, soil, or other loose material to and from the construction site shall be tarped and maintain a minimum two feet of freeboard.

2. Vehicle exhaust results from internal
combustion engines used by construction equipment and vehicle which results in emissions of NOx, VOCs, and CO. Such emissions will be below SCAQMD thresholds, but should be further reduced through the use of project design features and mitigation.

5.10-b The following shall be adhered to during project grading and construction to reduce VOC, NOx, and CO from construction equipment: a) Heavy-duty diesel-powered construction equipment manufactured after 1996 (with federally mandated "clean" diesel engines) shall be utilized. b) The engine size of construction equipment shall be the minimum size.
c) The number of construction equipment operating
simultaneously shall be minimized through efficient management practices to ensure that the smallest number is operating at any on time. d) Construction equipment shall be maintained in tune per the manufacturer’s specifications.
e) Catalytic converters shall be installed on gasolinepowered equipment.. f) Diesel catalytic converters shall be installed. g) Diesel powered equipment shall be utilized in lieu of electric equipment.

3. The application of architectural coatings
(exterior/interior paint and other finishings) would produce VOC emissions that would exceed the SCAQMD’s quantitative significance threshold of 75 pounds per day. This impact is considered significant.

5.10-c The project developer shall use zero-Volatile Organic Compounds (VOC)-content architectural coatings during project construction/ application of paints and other architectural coatings to reduce ozone precursors. If zeroVOC paint cannot be utilized, developer shall avoid application of architectural coatings during the peak smog season: July, August, and September. Developer shall procure architectural coatings from a supplier in compliance with the requirements of SCAQMD’s Rule 1113 (Architectural Coatings).

2. Noise levels associated with the commercial
activities would vary depending on the number of delivery trucks, loading dock areas and customer traffic generated by the commercial site. Similarly, HVAC equipment noise would vary depending on the number and types of equipment selected. Typical roof-top HVAC packaged units generate noise levels of approximately 70 dB at ten feet from the source. These noise sources may result in significant impacts depending on their make, model, location, proximity to adjacent receptors, etc.

5.11-b Individual acoustical analyses shall be prepared as part of site plan/development plan review for future commercial development applications submitted to the City, to ensure noise levels would comply with the City's Draft General Plan noise standards (maximum exterior noise levels of 65 dB CNEL; maximum interior noise levels of 45 dB CNEL) and not result in significant noise impacts at adjacent park land or residences. The applicant for each commercial development proposal would have the responsibility to commission or fund the required acoustical analysis. Although the future building-specific noise study will determine exact specifications, it is likely that interior noise mitigation would consist of sound-rated windows and mechanical ventilation systems for the commercial buildings. All required noise control measures identified in the acoustical analysis shall be made conditions of ultimate development approval to ensure that all measures are implemented to fully mitigate anticipated noise impacts.

2. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

3. Traffic-related noise exposure levels within
exterior use areas for the schools (i.e., playground, sports fields, athletic courts, etc.) could exceed acceptable noise standards, thereby resulting in potentially significant noise impacts. Future school buildings that are located in areas exposed to a noise level greater than 60 dB CNEL could exceed an interior noise level of 45 dB CNEL. This would result in a potentially significant impact. There are also residential areas proposed immediately adjacent to the north and east of the elementary school site. Specific residential setback information and the location of the schools facilities are not available. Therefore, until more specific

5.11-c For the high school site, the specified noise barriers along Ramona Boulevard and Cawston Avenue shall be installed to protect exterior use areas of the site from traffic-related noise; OR if the School District desires to forego the construction of the specified noise barriers in favor of selective location of exterior use space, a site specific acoustical analysis shall be prepared to determine adequate noise control for traffic-related noise (i.e., use of buildings to shield exterior use areas, etc.), to ensure that noise levels do not exceed 65 dB CNEL at exterior use areas. The School District would have the responsibility to commission or fund the acoustical analysis to evaluate traffic noise control if the sound walls specified herein are not incorporated into the high school development design. All required noise control measures identified in the acoustical analysis shall be made conditions of development approval.

3. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

5.11-d A Notice-to-Property Owner shall be recorded on a separate buyer information sheet with the final map providing notice to potential future property owners in the vicinity of the school site (i.e., Planning Areas 1, 3 and 19), stating that they could be exposed to noise associated with outdoor activities at the high school. The disclosure will function to make potential buyers aware of the anticipated noise levels/impacts, such that particularly noise-sensitive individuals would have the opportunity to decide against purchase of a home which is subject to these periodic noise conditions.

4. Two new freeways, State Route 79 (SR 79)
and Mid County Parkway (MCP) are currently in various planning stages. Detailed design drawings are not available for these two freeways. However, it is anticipated that the alignments of both freeways would be located at least 1,000 or more feet from the project site. As the area develops, there would be buildings and other structures that would most likely provide shielding between the freeways and the project site that would substantially attenuate the traffic noise. However, for the purposes of the project noise analysis it was conservatively assumed that the potential noise contribution from future SR 79 and MCP freeways would be 60 dB CNEL at the north and east boundaries of the project site.

5.11-e For residences proposed within the future 60 dB CNEL contour, an interior acoustical analysis shall be required prior to the issuance of building permits to ensure that the interior CNEL would not exceed 45 dB. Interior noise mitigation would most likely consist of sound-rated windows and mechanical ventilation systems for the homes. All required noise control measures identified in the acoustical analysis shall be made conditions of building permit issuance.

4. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

during sensitive time periods for adjacent land uses is considered a significant nuisance. As such, project generated construction noise would pose a potentially significant effect on noise-sensitive

5.11-f Future project-related site preparation and construction activities shall be limited to the hours between 7:00 am and 6:00 pm, Monday through Saturday. No construction shall occur on Federal holidays (e.g., Thanksgiving, July 4th, Labor Day, etc.). Construction equipment maintenance shall be limited to the same hours. Non-noise-generating

1. Due to the historic use of approximately 20
acres of the property as a heifer raising farm, the presence of manure may result in significant environmental impacts related to methane gas exposure.

5.13a In order to ensure that methane hazards do not exist on the 20 acre portion of the site formerly used for heifer raising activities, the Riverside County’s Methane Investigation Protocol shall be followed during and after site preparation. After grading of the 20 acres, methane gas sampling and any associated mitigation mechanism installation shall occur in accordance with the most recent Riverside County Department of Environmental Health protocols.

1. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

2. The issuance of the Regional Water Quality
Control Board’s "no further action" letter indicates that hazardous materials previously present on the site have been removed to a level that no longer poses a threat to the environment. Therefore, while the project site contains historic environmental hazards, these hazards have been removed and would no longer pose significant health risks to the public or environment. That said, regulatory procedures may be required to officially determine the site safe for reuse.

5.13b The Regional Water Quality Control Board and Department of Health Services shall be notified of potential site reuse in accordance with the December 26, 2001, "no further action" letter provided for the remediated leaking underground storage tanks. These agencies may require additional processing or testing depending on the ultimate reuse of the specific area contaminated. In order to ensure that regulatory compliance has been met, on-site soils shall be tested prior to grading to determine the presence of contaminants. Testing results will help determine if permissible levels of contaminants have been exceeded. If levels have been exceeded, impacted soils shall be remediated in accordance with Riverside County Department of Health Service protocol.

2. Potential impacts would be significant but
incorporation of mitigation will reduce impacts to below a level of significance.

3. Historic windmills were often powered by
diesel fuel. The diesel fuel source was often stored in underground storage tanks. During the Phase I Site Assessment, diesel storage tanks were not noted nor did they appear on federal or state databases within the vicinity of the old windmill. That said, often underground storage tanks are unreported and therefore could be discovered during grading. If an underground storage tank or stained soil or soil with a petroleum hydrocarbon odor is uncovered, a potentially significant impact could occur.

5.13c The former windmill site shall be flagged prior to site grading.

During site grading near the former windmill site, a qualified hazardous materials specialist shall monitor grading activities. If an underground storage tank or petroleum hydrocarbon odor-laden soil is uncovered near the old windmill site, grading and site work shall cease and the Regional Water Quality Control Board and Riverside County Department of Health Services notified. A remediation plan shall be developed to ensure that all contaminated soil and structures are removed, handled and disposed of in accordance with existing state and local regulations. Sampling in the area of impacted soils shall continue until contaminant levels reach an acceptable risk.

beneath the diesel above ground storage tank located northwest of the reservoir, near the irrigation groundwater well located southwest of the reservoir and on the floor of the equipment shed, beneath three oil containing 55-gallon drums.

5.13d In order to mitigate for potential hazards associated with petroleum stained soil beneath diesel storage tanks and on the floor of the equipment shed beneath 55-gallon oil storing drums, collection of surface and near surface samples by a qualified hazardous materials specialist must occur. Following removal of the equipment shed, observations will be made for any stained soil beneath the shed. If stained areas are observed, surface and near surface samples shall be collected. Testing for contaminant levels must occur and an assessment of significance under state and local hazardous material regulations must follow. Once contaminant levels are determined, the Regional Water Quality Control Board and Riverside County Department of Environmental Health must be contacted to determine the proper mitigation method prior to site redevelopment. Any soil and other materials contaminated with hazardous materials may be considered hazardous waste and therefore must be disposed of in accordance with federal, state and local regulations.

SECTION 2.0

INTRODUCTION

2.1 PURPOSE AND SCOPE OF THE RECIRCULATED DEIR
A Draft Environmental Impact Report (DEIR) for the Villages of San Jacinto Specific Plan was originally circulated for a 45-day public comment period in April 2006 (State Clearinghouse No. 2004122132). After the close of public review, the project applicant proposed several project description changes, including a revised drainage scenario, an extension of the project build-out, and inclusion of a development agreement as an additional discretionary action. As Lead Agency, the City of San Jacinto determined that these changes necessitated a Recirculated Draft EIR (RDEIR). Consequently, the City prepared an RDEIR to address the project description changes, which was circulated for a 45-day public review period in January 2007. Although the entire EIR was recirculated, only the environmental topics that were revised were subject to an additional review and comment period by the public: Those topics included geology and soils, water quality and hydrology, air quality, noise, and public services and utilities. During March 2007, a Final EIR was prepared to address comments received during the two public review periods. The City Planning Commission recommended approval of the project and certification of the Final EIR in April 2007. Minor changes in the project description delayed consideration of the project before the City Council until June 2008, and subsequently the project was continued in order to respond to questions, comments, and concerns raised at the June 2008 City Council meeting. Partially in response to City Council comments and current market demand, the applicant chose to update the Villages of San Jacinto Specific Plan and the Land Use Plan and to recirculate the EIR a second time to adequately notify the public of the revised project's potential environmental impacts.

Section 15088.5 of the State California Environmental Quality Act (CEQA) Guidelines requires lead agencies to recirculate an EIR when significant new information is added to the EIR after public notice is given of the availability of the DEIR for review but before certification. New information can include changes in the project or environmental setting as well as additional data or other information. Since new information that was not previously described in the April 2006 DEIR or the January 2007 RDEIR has become available, the City has determined that it is appropriate to prepare this RDEIR No. 2 for public review.

As required by State CEQA Guidelines Section 15088, the City will evaluate comments received on the RDEIR No. 2. The comments and responses will be included in the Final EIR as a separate section along with revised EIR text necessitated by the response to comments (if necessary). Comments on the RDEIR No. 2 should be limited to the EIR sections/environmental issues that were modified. The following section describes the new information analyzed in this

2.0 INTRODUCTION
Villages of San Jacinto EIR 4307-01
August 2009 2-2
RDEIR No. 2. The RDEIR No. 2 will retain the same SCH number (noted above) in order to establish a reference to the prior documents prepared for this project.

2.2 BACKGROUND AND CONTENT OF THE RECIRCULATED
DEIR
Consistent with the requirements of Section 15088.5(c) of the State CEQA Guidelines, this RDEIR contains all sections of the DEIR. However, in accordance with CEQA requirements, comments on the RDEIR shall be limited to the EIR sections that have changed. The following sections have been modified. All section numbering is consistent with the section numbering of the April 2006 DEIR.

Section 1.0, Executive Summary: The Executive Summary has been updated to reflect the revised project description, all new mitigation measures, and any additional significant impacts that have occurred due to project changes.

Section 2.0, Introduction: This section includes a summary of all sections that have changed since preparation of the April 2006 DEIR and January 2007 RDEIR, and a brief description of the history of the project's EIR process to date.

Section 3.0, Project Description: Project features that have been revised include the project site plan, mixture of land uses, drainage and other infrastructure components of the Specific Plan, the tentative map, and construction phasing. Graphics in this section have been revised to show those changes.

Section 4.0, Environmental Setting: This section has been updated to describe changes in existing land use on the site since preparation of the April 2006 DEIR and January 2007 RDEIR.

Section 5.1, Land Use, Planning, and Zoning: This section has been revised to reflect the newly proposed land use plan and its relationship with the existing City General Plan. Since the City's General Plan was being updated during preparation of the original DEIR, the revised RDEIR section has been updated to reflect the final, adopted General Plan Update (May 2006).

The land use graphics have also been updated to reflect the revised land use plan and tentative map. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.2, Landform Alteration and Aesthetics: This section has been revised to reflect revised visual resource General Plan policies included in the 2006 General Plan Update, newly proposed land uses, and revised open space corridors that may impact the ultimate visual appearance of the site once developed. The discussion of existing visual quality has been updated to reflect the changed site appearance including absence of the cattle feed lot and removal of

most of the agriculture. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance and the potential visual impact of a proposed 11-foot sound wall. Updated photos of the project site are also included.

Section 5.3, Agricultural Resources: This section has been amended to reflect the fact that cattle are no longer being raised on the site and the majority of agricultural operations have ceased. The impact analysis has been revised to provide a discussion of each CEQA threshold of significance. There is also a discussion which explains the reasons there are no feasible mitigation measures to replace converted farmland.

Section 5.4, Biological Resources: This section has been revised to clarify that mitigation for project impacts to jurisdictional wetlands would be provided off-site since the on-site wetlands were found to be of low overall quality (containing large quantities of non-native species), and do not provide high quality habitat for wildlife species due to the surrounding agricultural lands.

The impact analysis has been revised to provide a discussion of each CEQA threshold of significance and to clarify minor technical specifics regarding the status of species found or expected to be encountered onsite.

Section 5.5, Cultural Resources: This section was revised to clarify the lack of historical integrity of the onsite structure and to explain the existing Soboba Consulting Services Contract which helps avoid potential impacts to unmarked Native American burial sites or other impacts to lands considered sacred by local Native American peoples. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.6, Geology and Soils: This section has been amended to reflect the modified site plan and to show the structural setback zones on the updated land use plan. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.7, Paleontological Resources: The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.8, Water Quality and Hydrology: This section has been revised to reflect impacts associated with changes in the updated drainage study provided in Appendix G and includes the updated Drainage Plan depicted in the Specific Plan. It also contains a summary of updated water quality issues discussed in the revised Specific Plan and in the Lake Preliminary Design Report (Pacific Aquascape, Inc. 2009). The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.9, Transportation, Circulation, and Access: A modified traffic study has been prepared to reflect the revised project and changed surrounding circulation system conditions, and is summarized in this section. The entire updated traffic report is contained in Appendix H.

This analysis also includes a comparison of the project to the South Coast Air Quality Management District's Local Significance Thresholds. Construction and operational emissions have been revised using the current air quality model as well as the land uses and trip generation rates associated with the revised project. This section also includes a discussion of greenhouse gases and global climate change, in order to comply with legislative and CEQA mandates that have been established subsequent to the preparation of the DEIR and first RDEIR. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance. Revised and new air quality models are contained in Appendix I.

Section 5.11, Noise: The acoustical analysis has been updated to reflect changes in the new traffic report as well as the revised land use plan. Revised noise analysis models are contained in Appendix J. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.12, Public Services and Utilities: The revised drainage plan has been incorporated into the Public Services and Utilities section to assess the potential impacts to stormwater runoff from development of the proposed project. This section includes figures that update the water and sewage systems to reflect changes in the Specific Plan. In addition, development impact fees, consumption, and other project impacts have been updated to reflect the revised unit number, commercial square footage, and related impact discussions. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 5.13, Hazards/Risk of Upset: This section reflects changes in existing site conditions including removal of cattle and some of the buildings. The impact analysis has been revised to provide a discussion of each individual CEQA threshold of significance.

Section 6.0, Cumulative Impacts: This section has been updated to include new projects that have been proposed since 2005 and to confirm the status/project descriptions of all projects that were listed in the 2006 Draft EIR. Projects that were included in the original cumulative impact analysis that are no longer active/being contemplated have been removed. The cumulative impact analysis has been revised based on the City's updated list of active projects.

Section 7.0, Effects Found Not to be Significant: The population and housing discussion has been updated to reflect the correct number of housing units.

2.6 USES OF EIR/TYPE OF EIR
As the designated Lead Agency, the City of San Jacinto has assumed responsibility for preparing this document. The RDEIR No. 2 has been made available for review to the public and public agencies for 45 days to provide comments on the "sufficiency of the document in identifying and analyzing the possible impacts on the environment and ways in which the significant effects of the project might be avoided or mitigated" (Section 15204 of the CEQA Guidelines).

The proposed Villages of San Jacinto RDEIR No. 2 is intended to be a "project" EIR. As stated in CEQA Guidelines Section 15161, a Project EIR "should focus primarily on the changes in the environment that would result from the development project. The EIR shall examine all phases of the project including planning, construction and operation." Specific project details, including overall planning, construction, and operation, are known at this time; therefore, a project-specific level of analysis is appropriate for this RDEIR.

Per CEQA Guidelines Section 15123, an EIR shall contain a summary that identifies each significant effect of the project and mitigation measures (See Table 1-2, Summary of Environmental Impacts) as well as “areas of controversy” and “issues to be resolved.” The project assumes that the locally preferred alignment of a future State Route 79 corridor is chosen.

Some property owners in the vicinity have raised objections at prior public hearings for this project regarding the locally preferred alignment.

Eastern Municipal Water District (EMWD) requested in its May 16, 2006 letter responding to the April 2006 Draft EIR that they would like between a 1,320 to 2,000 foot buffer between its water reclamation facility and the nearest residential areas within the proposed project. As discussed in Section 5.1.4, the nearest residential lots to the treatment plant would be located over 1,000 feet from the plant boundary and would be separated by mixed use, commercial, recreation and internal roadways.

2.8 ISSUES TO BE RESOLVED
Section 5.9, Transportation, Circulation and Access, indicates that in the absence of planned regional transportation facilities (i.e., the Mid-County Parkway or MCP and SR-79 improvements), the project would contribute to a significant unavoidable impact for cumulative traffic conditions if the MCP and SR-79 projects are not in place upon completion of the first phase of project development. Because the City can not guarantee that these regional facilities would be in place prior to project build-out, a significant, cumulative impact to regional traffic may occur in the absence of these facilities.

SECTION 3.0

PROJECT DESCRIPTION

3.1 PROJECT LOCATION
The proposed project is located in the City of San Jacinto (the City) in northwestern Riverside County, California (Figure 3.0-1, Regional Map). The project site is located in the northwestern portion of the City (Figure 3.0-2, Vicinity Map). The project is located along Sanderson Avenue, which is one of the City's main north–south transportation routes. The project site is bordered by undeveloped agricultural land to the north (and future westward extension of Ramona Boulevard), Sanderson Avenue to the east, Odell Avenue to the west, and undeveloped agricultural land and a municipal wastewater treatment plant to the south (Figure 3.0-3, Site Location Map). The proposed project is scheduled to be constructed in several phases (see Phasing and Construction Planning, page 3-18).

Land uses in the project area consist mainly of agricultural operations, including sod farms, dry farming, animal grazing pastures, and dairies. Several parcels within this portion of San Jacinto are in the process of being developed with residential subdivisions or commercial centers. Two drainage features, associated with the nearby San Jacinto River, are located within the vicinity of the project: Casa Loma Canal and San Jacinto Reservoir. The Colorado River Aqueduct is located north of the project. The Eastern Municipal Water District (EMWD) Hemet/San Jacinto Regional Water Reclamation Facility is located directly south of the project site.

State Route 79 (SR-79) and Sanderson Avenue serve as major north–south transportation corridors through this portion of the City. Ramona Expressway, located north of the project site, serves as the main east–west arterial through the City. Enhanced access to the western portion of San Jacinto will occur through the future widening and realignment of SR-79 and Ramona Expressway.

3.2 PROJECT SITE BACKGROUND
The project site is approximately 475.1 acres in size. The project site has been used as pasture land and/or a farming operation, similar to surrounding properties, for over one hundred years. In 1978, a 20-acre area of the project site was converted to a cattle raising facility. In 1997, a majority of the remaining property was leased to the Quality Turf Company. The San Jacinto Valley has traditionally supported agriculture and rural residential land uses, but has recently been experiencing increased urbanization.

One residence and one small outbuilding are located on the project site (see Figure 5.13-1). The residence and the outbuilding (likely a former equipment storage shed) are both abandoned. A

3.0 PROJECT DESCRIPTION
Villages of San Jacinto EIR 4307-01
August 2009 3-2
portion of the project site is currently used for sod farming generally in the northwestern portion of the site.

3.3 SITE DESCRIPTION
The site is generally flat and is located on the alluvial plain of the San Jacinto River. The site elevation above sea level ranges from 1,455 feet along the northern edge to 1,490 feet in the southeastern corner. The southeastern corner of the site is a former cattle feed lot with several remaining shade structures associated with that operation. The remainder of the land consists primarily of vacant former agricultural land. Vegetation on site consists of weedy invasive species that have accumulated since the majority of agricultural production was discontinued.

There are scattered sod fields in the northern portions of the property, which is the only remaining agricultural operation. Several unnamed, unimproved dirt roadways traverse the site and are associated with former and current agricultural operations. Irrigation canals run along the edges of fields in support of sod farming activities. A detention basin is located along the northcentral edge of the project site.

3.4 PROJECT OBJECTIVES
Specific objectives for the proposed project include the following:
• Provide for the establishment of a master-planned community through implementation of a Specific Plan, consisting of a maximum of 1,329 dwelling units, which is consistent with the scale and character of planned uses in surrounding areas. • Provide a variety of detached single-family lot sizes in traditional subdivision layouts that are marketable within the evolving economic and demographic profile of the City of San Jacinto.
• Provide public and private recreational amenities for the benefit of residents of this community and of the City of San Jacinto.
• Provide drought-tolerant and water-efficient landscaping for the community. • Incorporate recycled water from EMWD to supply the lake and irrigate landscaping to minimize the use of potable water.
• Provide development opportunities for municipal, office, professional, and neighborhood retail commercial land uses within the community to support the economic growth of the City and to reduce the reliance of automobile use within the surrounding community. • Consider topographic, geologic, hydrologic, and environmental opportunities and constraints to create a design that safely accommodates seismic and hydrologic hazards.

• Provide a system of public and community facilities within residential neighborhoods to support development in an efficient and timely manner.
• Provide a development with unified design elements, such as architecture, landscaping, color palette, paving, walls, fencing, signage, and entry treatments. • Develop an environment that is visually attractive, efficient, and effectively organized, which includes a pleasing landscape palette.
• Integrate the project with the character of the surrounding community and establish development that results in logical, coordinated growth. • Establish a circulation system that meets projected traffic volumes and accommodates a variety of transportation modes and encourages alternatives to automobile use within the community.

3.5 PROJECT FEATURES
The project would consist of development of an existing agricultural operation into a suburban development, including residential, commercial, public facility, and open space uses. The 475.1- acre site would be divided into several "Planning Areas" (PAs). Each PA would consist of a distinct land use type. Land use statistics are summarized in Table 3.0-1, Planned Land Uses, and land uses and densities anticipated in each PA are listed in Table 3.0-2, Planned Land Uses by Planning Area. Figure 3.0-4, Specific Plan Land Use Plan, provides a generalized site development plan depicting each PA and associated land use. Table 3.0-2 provides a summary of the intensity of use planned within each PA.

The following is a detailed description of each of the proposed land uses within the proposed project, which is illustrated on Figure 3.0-4, Specific Plan Land Use Plan, and delineated in Table 3.0-1, Planned Land Uses.

Residential
Residential land uses would consist of two General Plan density categories: Low Density Residential, LDR (2.1 to 5.0 dwelling units/acre (DU/AC)), and Medium Density Residential, MDR (5.1 to 10.0 DU/AC) (San Jacinto General Plan 2006). The LDR category will be built within PAs 3, 5, 6, 13, and 19 and will result in a maximum of 359 dwelling units on 80.6 acres.

Each residential lot will be a minimum of 6,000 square feet, and overall density will be 4.5 dwelling units per acre. The MDR category will be built within PAs 1, 2, 4, 7, 8, 9, and 10 with a total of 349 residences having 5,000-square-foot minimum lot sizes and 308 residences having 4,000-square-foot minimum lot sizes. In the event that PA 14 is not used by the San Jacinto Unified School District for a proposed new high school, a portion of this area (45.5 acres) would be developed with 200 residential lots under the LDR designation, and the remaining portion

Commercial
Commercial development would be focused in the southeast corner of the project site within PA

that allows for a wide range of businesses, including grocery store, drug store, cleaners, restaurants, fast food, and specialty stores. The Specific Plan for the project (T&B Planning Consultants 2009) includes Conceptual Design Guidelines and Development Standards for commercial development of this PA. Comprehensive Design Guidelines will need to be reviewed and approved by the City prior to development of the PA.

Mixed-Use
Mixed-use development will be provided within the 26.3-acre PA 12. This designation is intended to provide for a broad range of land uses, with the primary focus on municipal uses and other development, such as business and professional park uses, including dental and medical offices, real estate offices, and banks. This area could also provide accessory uses to the primary facilities, such as coffee shop, printers, and postal/shipping outlets. This designation provides for a maximum of 343,000 square feet of building area and will have a maximum height limit of 45 feet. Conceptual Design Guidelines for commercial uses are provided in the project Specific Plan, but Comprehensive Design Guidelines will need to be reviewed and approved by the City prior to development of the PA.

Schools
As noted above in Table 3.0-2, PA 14 is designated for a proposed high school by San Jacinto Unified School District (District). The 69.1-acre high school site would be located southwest of the future intersection of Cawston Avenue and Ramona Boulevard. Preliminary plans for the school include baseball and softball fields, a track/football stadium, gymnasium, performing arts facility and classroom space for up to 2,000 students. Final plans for the school would be processed separately from the Villages of San Jacinto Specific Plan through the District Board of Trustees and the California Division of the State Architect. If the San Jacinto Unified School District does not choose to construct a high school on this site, it will instead be used for residential uses. Under this scenario, PA 14 would be developed with 200 low-density residences (minimum 6,000-square-foot lots) and 113 medium-density residences (5,000-square-foot lots) along with a 2-acre park site.

3.0 PROJECT DESCRIPTION
Villages of San Jacinto EIR 4307-01
August 2009 3-15
Public Parks
The proposed project includes three public parks totaling approximately 41 acres. The largest of the public parks is the 33.4-acre Community Park in Planning Area 15C north of Bridge Street in the southern portion of the proposed development. This park will provide soccer and baseball fields, concession area, as well as barbeque and picnic areas overlooking the proposed lake.

Public parks in Planning Areas 15B and 15D provide just over seven acres of various active and passive recreational opportunities.

Private Parks
The two private parks in Planning Areas 15A and 15E will provide passive recreation for nearby residents such as tot lots, shade structures, pathways and picnic areas.

Infrastructure
The Villages of San Jacinto Specific Plan (T&B Planning Consultants 2009) details a number of infrastructure plans that will be incorporated into project development. These include a Circulation Plan, Drainage Plan, and Water and Sewer Plans. In addition, a Lake Preliminary Design Report was prepared to address lake design and water quality management systems. These plans are summarized below and discussed in more detail in the relevant sections of this EIR.

3.0 PROJECT DESCRIPTION
Villages of San Jacinto EIR 4307-01
August 2009 3-16
Circulation Plan
Roadways would be located throughout the development and would provide access to and from as well as within the project. Sanderson Avenue and Odell Avenue would serve as primary access points for the project. Once constructed, Ramona Boulevard would provide connection at the north edge of the project site. Cawston Avenue would serve as the major north–south arterial through the project while De Anza Drive would serve as the major east–west arterial within the development, taking access from Sanderson Avenue and connecting to Cawston Avenue. Bridge Street will also provide east–west access at the southern end of the development from either Cawston Avenue or Sanderson Avenue. The internal roadway network will include three streets designed as Modified Local Streets (Streets A, B, C) that connect the various PAs. The network will also include standard Local Streets that will connect individual neighborhoods. Roadway classifications are in compliance with City of San Jacinto and County of Riverside Road Standards.

Water Plan
Water service will be provided to the project by EMWD and be extended into the project via new conveyance facilities consistent with the EMWD's Northwest San Jacinto Area Master Plan.

Domestic water will be conveyed via a proposed 16-inch pipeline in Sanderson Avenue and 12- inch pipelines within De Anza Drive; Bridge Street, Ramona Boulevard; and Streets A, B, and C.

Recycled Water Service
Recycled water pipelines will be installed concurrently with domestic lines. Recycled water would be utilized to maintain the lake water level as well as common area irrigation needs throughout the proposed community. Recycled water will not be used for private landscaping such as front or back yards. Proposed 8-inch recycled water lines will be installed within internal project roadways.

Initially, the recycled water system will be provided from domestic water sources within Sanderson Avenue and Ramona Boulevard, but, ultimately, a pumping facility will use stored recycled water in the lake to supply water for irrigation. A Water Supply Assessment was completed by EMWD. The developer will be required to prepare a Plan of Service in accordance with EMWD standards prior to final engineering and construction of all domestic and recycled water lines. This will ensure that pipe sizing and any additional infrastructure facilities are adequate to serve the project and are in conformance with EMWD's Master Plan.

Sewer Plan
The project site is within the EMWD service area for wastewater collection and treatment. There is an existing 8-inch force main along Sanderson Avenue which conveys flows into an existing treatment facility located just south of the project boundary. Proposed sewer facilities will range between 12 to 30 inches per the EMWD Master Plan. Streets A, B, and C will have 10-inch lines

3.0 PROJECT DESCRIPTION
Villages of San Jacinto EIR 4307-01
August 2009 3-17
that flow to a 15-inch line in Cawston Avenue, while an additional 15-inch line is planned for Odell Avenue. Both of the 15-inch lines will gravity flow toward a 30-inch line in Ramona Boulevard, which will then continue to gravity flow toward the existing EMWD treatment plant.

A Plan of Service Study will be completed in accordance with EMWD standards prior to final engineering and construction of all sanitary sewer lines. This will ensure that pipe sizing and any additional infrastructure facilities are adequate to serve the project and are in conformance with EMWD's Master Plan.

Drainage Plan
The project site generally drains in a northwesterly direction toward the San Jacinto River, primarily in a sheet flow pattern. The northerly portion of the project site is within the 100-year floodplain. The drainage plan provides 100-year flood protection for the interim and ultimate conditions. The interim condition is based on the absence of the San Jacinto Master Drainage Plan (MDP) systems being in place, while the ultimate condition assumes all the MDP facilities are constructed and functional. The implementation of the San Jacinto MDP is based on the timing of the development of the surrounding area. As a result, the construction timeline for the proposed San Jacinto MDP drainage facilities is unknown. Consequently, the project incorporates a drainage plan that will not impact upstream and downstream property owners but will provide flood protection for the overall project site. The Drainage Plan will incorporate a vegetative channel and a detention/water quality basin, which are designated as Line V and Detention Basin V. These two facilities are the major backbone infrastructure that will collect the runoff that emanates from off-site and on-site areas. Line V and Detention Basin V have been designed to convey and control the interim flow rate and ultimate flow rate. The interim flow rate results in a runoff rate that exceeds the ultimate condition flow rate. The interim condition will require the construction of two interim culvert facilities and the reconstruction of an earthen roadway to eliminate ponding east of the DeAnza Drive and Sanderson Avenue intersection.

These interim drainage facilities are required to control and convey the interim flow rates originating from the off-site area. Several storm drain laterals will provide flood protection for the on-site PAs. Further details of the Drainage Plan are contained in Section 5.8 Water Quality and Hydrology.

Lake Preliminary Design Report
This report discusses safety features for the proposed lake shoreline, water depth and temperature, treatment of runoff, and water quality management. The treatment process involves reduced concentration of dissolved pollutants, nutrients, and salts through flushing of the lake water volume by utilizing the lake as the irrigation supply source; reduction of nutrient concentrations from inflows, nitrogen and phosphorous, and prevention of algal blooms by using constructed gravel biofilter beds that utilize "biological filtration," and maintaining oxygen levels

3.0 PROJECT DESCRIPTION

through aeration promoting oxygen exchange to prevent anaerobic conditions, which allows natural processes to occur, such as denitrification for removal of nitrogen. The lake operation and maintenance program also includes routine debris removal, algae control, aquatic weed control, pump maintenance, and biofilter maintenance. These processes ensure continued aesthetic appeal and desirable water quality as well as control of vectors, such as mosquitoes and flies.

Tentative Map
A draft tentative map (TM 36188) has also been prepared for the project. Figure 3.0-5, Tentative Tract Map, shows individual residential lots, mixed use and commercial areas and accessory uses, including open space, lakes, and roadways. In summary, the Tentative Tract Map, which further defines the Specific Plan Land Use Plan (described above), would allow the following housing units and other land uses to be developed on the project site:

Unit Type Summary
• 6,000-square-foot lots: 359 units
• 5,000-square-foot lots: 349 units
• 4,000-square-foot lots: 308 units
TOTAL: 1,016 units
• 69.1-acre high school site
• 22.7 acres of commercial uses
• 26.3 acres of mixed-use
• 5.1-acre lake house and Swim Lagoon
• 43.0 acres for parks

Phasing and Construction Planning
The project is designed to be developed in four phases over an approximate 9-year period in response to market demands and according to a logical and orderly extension of roadways, public utilities, and infrastructure. Development may occur more rapidly or more slowly, depending on the marketability of the community. Project Phasing is shown on Figure 3.0-6, Conceptual Phasing Plan, and detailed in Table 3.0-3, Project Phasing Plan. It should be noted that the public parks, the private lake, Lake House Beach Club and Swim Lagoon, drainage channels, and detention basins will be constructed as part of Phase I; and that the High School site (PA 14), may, if purchased by the school district, be developed earlier than indicated on the Conceptual Phasing Plan.

The project will be built out in four phases based on the absorption rate of the prior community phase. Each phase will entail fine grading (mass grading will be performed as part of Phase I), followed by installation of sewer, storm drain, and water infrastructure; installation of water crossings; installation of curb and gutter framework for the street system; paving; and construction of residences and commercial/mixed-use buildings. Phase I is anticipated to begin in the winter of 2011 and will last approximately 49 months. Phase I would include mass grading the entire site and will be finished upon completion of 431 residential units. Construction of Phase II will begin at roughly the time Phase I has sold out (estimated January 2016) and will take approximately 24 months to complete. Phase II will be finished upon completion of 322 residential units. Phase III will begin at roughly the time Phase II has sold out (estimated January 2018) and will take approximately 72 months to complete. Phase III will be finished upon completion of 263 residential units, and the high school (or 313 additional residential units if the high school is not developed on-site). Phase IV will begin at roughly the time Phase III has sold out (estimated January 2024) and will take approximately 120 months to complete. Phase IV will be finished upon completion of the project’s commercial/mixed-use development. Completion of the project is estimated to be by December 2033.

3.7 INTERAGENCY CONSULTATIONS
The project will or has required the City to engage in the following interagency consultation processes:

Senate Bill 18
Senate Bill 18 requires a City to notify any Native American tribe or group who has previously expressed interest in the project study area or who has historically inhabited the project area to determine if they view the project site as a significant point of ancestral heritage. This consultation is required when the City is considering a General Plan Amendment such as proposed for this project. The City conducted consultation per Senate Bill 18 during the early planning process for the project (2005). Given the elapsed time, the City will contact all applicable Native American groups during late summer/fall 2009 to determine if they have any further comments regarding the proposed project.

Federal Clean Water Act/California Fish and Game Code
Pursuant to Section 401 of the Federal Clean Water Act and Section 1600 of the California Fish and Game Code, any modification to surface waters must fist obtain a permit from the Regional Water Quality Control Board and California Department of Fish and Game, respectively. The applicant will be required to obtain permits to alter existing onsite water and/or wetlands prior to grading activities.

Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) The City is a signatory to the Western Riverside County MSHCP and therefore has the obligation to implement the MSHCP in accordance with all applicable protocols. The City reviewed the project biological resource studies to determine consistency with reserve design and other plan requirements. Although the project is not located within MSHCP “criteria cells,” the City contacted the Western Riverside County Regional Conservation Authority, the joint powers authority tasked with overall MSHCP implementation, to confirm that the project is not located within criteria cells and therefore submittal of the project for Joint Project Review was not necessary. The Western Riverside County Regional Conservation Authority confirmed that the project was not located within a criteria cell in a letter dated November 17, 2008.

Storm Water Pollution Prevention Plan
Pursuant to the National Pollution Discharge Elimination System, any project that would disturb soils during construction is required to prepare a Storm Water Pollution Prevention Plan. This

3.0 PROJECT DESCRIPTION
Villages of San Jacinto EIR 4307-01
August 2009 3-27
Plan shall be approved by the Regional Water Quality Control Board. The applicant will prepare and process this Plan prior to project grading.

Hazardous Material Closure/Reuse
In order to obtain permission for reuse of a site that formerly supported hazardous materials or substances (ie, such as methane or the former leaking underground storage tank), the Regional Water Quality Control Board and the Riverside County Department of Environmental Health must approve a closure and reuse plan prior to site disturbance. The applicant will prepare such a plan and process it through both agencies.

Water Supply Assessment
For all projects that would result in construction of more than 500 dwelling units, local municipalities must consult with the applicable water agency to determine whether adequate water supplies exist to serve the proposed project. Because the project proposes up to 1,329 dwelling units, the 500 unit maximum would be exceeded, therefore this interagency coordination requirement would be triggered. The City received a Water Supply Assessment from Eastern Municipal Water District on December 15, 2004. The City also received confirmation that the December 15, 2004 Water Supply Assessment was still valid in a May 11, 2009 letter.

SECTION 4.0

ENVIRONMENTAL SETTING
In accordance with Section 15125 of the CEQA Guidelines, the general environmental setting for the project area is provided in this section. More detailed descriptions of the setting specifically pertaining to each environmental issue are provided at the beginning of each impact issue area addressed in Section 5.0.

4.1 PHYSICAL SETTING
The site is generally flat and is located on the alluvial plain of the San Jacinto River. The site elevation above sea level ranges from 1,455 feet along the northern edge to 1,490 feet in the southeastern corner. The southeastern corner of the site is a former cattle feed lot with several remaining shade structures. The remainder of the land consists primarily of vacant former agricultural land. Vegetation on site consists of weedy invasive species that have accumulated since the majority of agricultural production was discontinued. There are scattered sod fields in the northern portions of the property, which is the site of the only remaining agricultural operation. Several unnamed, unimproved dirt roadways traverse the site and are associated with former and current agricultural operations. Irrigation canals run along the edges of fields in support of current or former sod farming activities. A detention basin is located along the northcentral edge of the project site. There is one abandoned residence and former storage shed located in the east central portion of the site (see Figure 5.13-1).

The San Jacinto River is the dominant landform in the project area. The river, which is located less than 1 mile from the project site, is contained within a broad valley formation that is characterized by flat, alluvial terraces surrounded by stark mountains. The project is surrounded by existing agricultural operations on three sides, with the San Jacinto Valley Regional Water Reclamation Facility along the southern boundary of the site. The San Jacinto River area comprises a flat, perennial river characterized by wetland vegetation within the immediate channel and then drier habitats, such as grassland and coastal sage scrub, further from the low flow area. Due to its flat nature and alluvial setting, much of the San Jacinto River floodplain has been utilized for active agriculture for over 100 years.

As discussed previously, agricultural operations on the site have mostly ceased to be active with the exception of some sod farming in the northwest portion of the site. However, the project site contains state-designated Prime Farmland, Unique Farmland, and Farmland of Statewide Importance. Section 5.3, Agricultural Resources, describes the impact of converting these designated lands in greater detail. There are no unique aesthetic or visual resources on site (see Section 5.2, Landform Alteration and Aesthetics, for additional clarification regarding on-site visual resources). Although the site is highly disturbed from a biological resource perspective,

4.0 ENVIRONMENTAL SETTING
Villages of San Jacinto EIR 4307-01
August 2009 4-2
sensitive and unique wildlife species exist on site (Section 5.4, Biological Resources, provides a greater description of on-site biological resources). The project site does not contain any unique cultural resources (Section 5.5, Cultural Resources, provides a greater description of on-site cultural resources). The project site contains two fault areas on site (see Section 5.6, Geology and Soils, for further discussion of on-site geotechnical resources). The site does not contain any natural hydrologic features; however, it is characterized by the on-site irrigation canals and detention basins. The project site is located near the San Jacinto River; the river's 100-year floodplain traverses part of the project site (see Section 5.8, Water Quality and Hydrology, for further discussion on the project's on-site hydrologic features).

On-site infrastructure includes dirt driveways/roadways, a septic system, well water service, and constructed agricultural detention basins to assist with on-site drainage. Currently, public utilities, including electric, gas, and phone service, are located on site.

4.2 APPLICABLE LAND USE PLANS
Section 15125 (d) of the CEQA Guidelines requires that a discussion of the project's relationship to the applicable general plan and relevant regional plans be provided. The consistency analysis for the proposed project with applicable plans, policies, and regulations is provided in Section

5.1, Land Use, Planning, and Zoning, of this EIR. The following is a list of plans, policies, and regulations that are applicable to the proposed project:
• City of San Jacinto General Plan
• City of San Jacinto General Plan Update
• City of San Jacinto Municipal Zoning Code
• Western Riverside County Multiple Species Habitat Conservation Plan • South Coast Air Pollution Control District Regional Air Quality Strategies • Southern California Association of Government's Regional Comprehensive Plan.

ENVIRONMENTAL ANALYSIS

5.1 LAND USE, PLANNING, AND ZONING

5.1.1 Introduction and Methodology
This section describes the planned land uses associated with the proposed Villages of San Jacinto Specific Plan and Tentative Map and discusses potential project impacts to land use, planning, and zoning that would occur as a result of project implementation. The following discussion includes a description of existing land uses surrounding the project site and provides an analysis of the proposed development's compatibility with planned and existing surrounding land uses.

The discussion also evaluates the consistency of the proposed project with all relevant plans and policies, including those policies and development standards of the City's General Plan, Zoning Ordinance, and the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP).

The character of existing land use was determined by field survey, review of aerial photography of the project site and surrounding area, and review of existing documentation and site descriptions. Issues of land use compatibility were analyzed in the context of existing and planned land uses, policies, and planning programs. In addition, issues of land use compatibility have been analyzed in the context of physical environmental factors, such as agriculture, noise, air quality, aesthetics, and traffic, discussed in detail in the respective sections of this EIR.

Applicable City and regional planning documents were reviewed to identify all applicable plans, policies, and development standards to evaluate potential project impacts to existing planning programs. A consistency analysis was conducted for each applicable policy identified and mitigation measures have been provided to address potential project inconsistencies with relevant plans and policies.

5.1.2 Existing Conditions
Existing Land Uses
The 475.1-acre project site is located in the northwest portion of the City of San Jacinto in an area consisting primarily of agricultural uses. The southeastern corner of the site is a former cattle feed lot with several remaining shade structures. The remainder of the land consists primarily of vacant former agricultural land. Vegetation on site consists of weedy invasive species that have accumulated since the majority of agricultural production was discontinued.

There are scattered sod fields in the northern portions of the property, which entail the only remaining agricultural operations.

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-2
As illustrated in Figure 5.1-1, Existing Land Uses, the project site is located in a rural area within approximately 1.25 miles south of the San Jacinto River. The north property boundary of the project site is generally bound by the proposed road alignment for the Ramona Boulevard extension. Beyond this proposed road extension, land uses north of the site consist primarily of cultivated agricultural use in addition to duck ponds, the Colorado River Aqueduct, and the Ramona Expressway. Agricultural land uses occupy most areas west of the of the project site and include cultivated lands and cattle operations. A municipal wastewater treatment plant is located directly south of the project site and the San Jacinto Reservoir is located southeast of the property. The east side of the project site is generally bound by North Sanderson Avenue.

Immediately east of North Sanderson Avenue, land uses consist of agricultural cultivation and low density residential use. Land use patterns begin to transition to urban-related uses continuing east-southeast of the project area toward downtown San Jacinto located southeast of the project site.

The project site is accessible directly from North Sanderson Avenue or indirectly via various agricultural roads taking access from the Ramona Expressway, Cottonwood Avenue, and Warren Road.

According to the Tentative Map/New Development Map accessed on the City's website (City of San Jacinto 2005), a number of new residential and commercial development projects have been approved or are in the City review process within the City including the area surrounding the project site. Figure 5.1-2, Surrounding Projects, depicts surrounding projects within the San Jacinto area at the time of EIR publication. Details of these projects can be found in Table 6-1, Cumulative Projects List, in Section 6.0, Cumulative Impacts.

Land Use Plans and Policies
City of San Jacinto General Plan
The City of San Jacinto General Plan identifies community goals and planning issues for future growth of the City and establishes goals and policies to provide a comprehensive basis for implementation of plans and programs to achieve community goals. The General Plan contains seven individual Elements: Land Use, Housing, Circulation, Natural Resources Management, Noise, Public Safety and Community Services and Facilities. Existing applicable land use designations and policies are addressed in the policy consistency analysis for the proposed project. The most recent General Plan was adopted on May 4, 2006, and the latest General Plan Land Use Map was approved in February 2009.

Figure 5.1-3, General Plan and Specific Plan Comparison, shows that the General Plan designations on the project site have a mix of land uses, which include Community Commercial (CC), Open Space Recreation (OS), Low Density Residential (LDR), and Medium Density Residential (MDR).

As shown on Figure 5.1-3, the easternmost portion of the site contains approximately 54.4 acres of the CC land use designation, which typically allows for development of a broad range of service and retail commercial activities at various densities. The central and western portions of the site contain about 44.7 acres of the Open Space land use designation, which is intended to maintain general open space areas for purposes of conservation of natural and scenic resources and protection of public property from natural hazards. Limited residential use is permitted in areas designated as Open Space at a maximum density of 1 unit per 40 acres and limited park and recreation uses are permitted at a maximum Floor Area Ratio (FAR) of 0.10:1.

The remaining portion of the site is designated LDR (136.5 acres) and MDR (239.5 acres). The northwest portion of the site is predominantly designated as LDR, which allows for detached single-family residential development at a maximum density of 5 units per acre. The MDR land use designation exists on approximately half of the site and permits single-family attached and detached units, duplexes, triplexes, fourplexes, townhouses, condominiums, and mobile home parks at a maximum density of 10 units per acre. Table 5.1-1, General Plan and Specific Plan Comparison, presents a comparison of acreage and dwelling units of the proposed Specific Plan and existing General Plan designations.

City of San Jacinto Zoning Ordinance
The Zoning Ordinance of the City of San Jacinto contains site-specific zoning designations and associated development standards that serve to implement the goals and policies of the General Plan.

As shown on Figure 5.1-4 Zoning and Specific Plan Comparison, the project site is currently zoned One Family Zone (R-1), Two Family Zone -Planned Unit Development Overlay (R-2 PUD), Multiple Family Zone (R-3), and General Commercial Zone (C-2). The distribution of zoning designations on the site generally corresponds with the land use designation with the southeast corner of the site zoned as C-2 for general commercial uses, most of the northwest portion of the site zoned R-1 for low density residential development, and the majority of the site zoned R-2 for medium density residential development. The main difference between the current zoning and proposed Specific Plan is that rather than high density residential as designated in the southwest corner of the site, the project will provide mixed use and park development in that area.

City of San Jacinto Redevelopment Plan
The City of San Jacinto and Soboba Springs Redevelopment Plans and corresponding 5-year implementation plans address issues related to eliminating blighted areas in designated redevelopment project areas. The Redevelopment Plans address a total of 27 project areas located primarily in the urbanized eastern portion of the City. Due to the location of the project area in the more rural western portion of the City, plans and policies associated with the Redevelopment Plans are not applicable to the proposed project.

Transportation Uniform Mitigation Fee 10-Year Strategic Plan (TUMF) The Western Riverside Council of Governments (WRCOG) is a council comprising members that represent 15 local jurisdictions in western Riverside County, including the City of San Jacinto. The WRCOG functions to facilitate collective examination by the various representative jurisdictions of issues that are regional in nature such as air quality and traffic. In June 2004, the WRCOG adopted the Transportation Uniform Mitigation Fee (TUMF) 10-Year Strategic Plan (TUMF) and Transportation Improvement Program Development Guidelines.

The purpose of the TUMF program is to establish a comprehensive funding source to mitigate the cumulative regional transportation impacts of new development on regional arterial highways (Parsons Brinckerhoff Quade & Douglas, Inc, June 2004). The TUMF program has five primary goals that are articulated as a basis for developing specific regional project priorities and selection criteria. These goals are summarized as follows:
• Sustain Mobility – Mitigate the transportation system impacts of new development • System Continuity – Enhance the continuity of the regional arterial highway system • Project Development – Encourage systematic project development and provide flexibility to advance TUMF projects promptly through completion
• Leverage Funds – Secure additional matching funds for TUMF system improvements • Regional Benefit – Ensure TUMF program revenues are distributed to maximize mitigation of new development impacts.

The TUMF program is intended to address cumulative traffic impacts of new development to the region; therefore, TUMF program funded improvements are focused primarily on regional arterial highways. New development in western Riverside County places additional demand on the regional transportation system to provide safe and convenient access for new residents and employees. The additional demand on the transportation facilities reduces mobility absent adequately and timely funded infrastructure improvements constructed to meet growing demands. As such, the WRCOG has developed and implemented the TUMF program which requires new development to contribute revenues to partially fund improvements that will mitigate the transportation impacts of new developments. TUMF investments are then focused on those regional facilities most impacted by new development.

Western Riverside County Multiple Species Habitat Conservation Plan The Western Riverside County MSHCP is a comprehensive, long-term habitat conservation program which addresses the needs of a variety of biological resources. The MSHCP provides for the conservation of approximately 160 species and covers approximately 1.25 million acres of land in Riverside County which is experiencing rapid urbanization. The primary goal of the MSHCP is to develop and manage sustainable preserve areas within existing and expanding urban areas. The preserve areas and management efforts contained in the final MSHCP will affect land use planning in the entire City of San Jacinto area.

Southern California Association of Governments Growth Management Plan The Southern California Association of Governments (SCAG) Growth Management Plan contains recommendations for methods to direct development and build-out of the region in

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-14
ways to minimize traffic congestion and protect environmental resources, including efforts to balance land uses, particularly jobs and housing. Goals of the SCAG Management Plan are reflected in the City's General Plan and individual plan elements.

South Coast Air Quality Management Plan
The South Coast Air Quality Management District (SCAQMD) Governing Board adopted the 2003 Air Quality Management Plan (AQMP) on August 1, 2003. The 2003 AQMP updates the attainment demonstration for the federal standards for ozone and particulate matter (PM10); replaces the 1997 attainment demonstration for the federal carbon monoxide (CO) standard, provides a basis for a maintenance plan for CO for the future; and updates the maintenance plan for the federal nitrogen dioxide (NO2) standard that the SCAB has met since 1992.

The South Coast AQMP includes a number of policies and measures to achieve federal and state standards for healthful air quality in the region. The City's General Plan strives to comply with the AQMP by planning land uses in relation to circulation systems, promoting commercial and industrial land uses with convenient access to transportation corridors, and encouraging a balance of land uses that facilitates a complimentary association between jobs and housing.

5.1.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on land use, planning and zoning if it:

1. Physically divides an established community.

2. Conflicts with any applicable plan, policy or regulation of an agency with jurisdiction over the project (including, but not limited to, the general plan, specific plan, local coastal program, zoning ordinance, etc.) adopted for the purpose of avoiding or mitigating an environmental effect.

3. Conflicts with any applicable habitat conservation plan or natural community conservation plan.

4. Introduces a land use that is incompatible with existing or proposed surrounding land uses.

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-15

5.1.4 Impacts
Would the project physically divide an established community? As described in detail in Section 3.0, Project Description, the proposed project would develop commercial, residential, recreation and school facility land uses in the Specific Plan project area.

Table 3-1 illustrates the total acreage committed to each proposed land use.

The City's General Plan Land Use Map and Zoning Ordinance generally designate the project site and adjacent surrounding land area for future residential and commercial development and, as such, a variety of residential/commercial developments have been approved in the vicinity or are in the City review process. According to the City's Tentative Map/New Development Map illustrating various development projects recently approved or pending City review, a number of new residential and commercial development projects have been approved, or are in the City review process, in the area surrounding the project site.

The project site's location in an existing rural area surrounded by land that currently supports agricultural uses is likely to result in a physical division of a relative contiguous rural area and associated agricultural community. That said, due to existing residential and commercial land use and zoning designations of the subject site and adjacent land, and the apparent pattern of pending residential and commercial development proposals in the vicinity of the project site, it is anticipated that the project area will experience a pattern of rural agricultural land use conversion to urban-type uses which would ultimately alleviate potential land use conflicts between existing agricultural uses and planned residential development. Therefore, no significant impacts related to the division of an established community would occur.

Would the project conflict with any applicable plan, policy or regulation of an agency with jurisdiction over the project (including, but not limited to, the general plan, specific plan, local coastal program, zoning ordinance, etc.) adopted for the purpose of avoiding or mitigating an environmental effect?
Land Use Plans and Policies
City of San Jacinto General Plan
The City requires that a Specific Plan be developed for all projects involving 100 acres or more.

Government Code Section 65450 states that a planning agency may "prepare specific plans for the systematic implementation of the general plan for all or part of the area covered by the general plan." The project, as proposed, will require an amendment to the General Plan Land Use Map to develop a Specific Plan and modify the land use designations of the project site to remove the HDR designation from the subject property and to reconfigure the existing CC, OS,

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-16
LDR, and MDR land use designations, and school site, consistent with the distribution of the land uses for the planned development of the proposed Specific Plan. The proposed Specific Plan is intended to incorporate and implement the comprehensive goals and policies of the City's General Plan for the more detailed development plan of the Villages of San Jacinto. The project land use scenario is generally consistent with the latest General Plan Update Land Use Plan.

Therefore, the potential inconsistency with the existing General Plan Land Use Map is considered less than significant from a Land Use Plan Map perspective.

Table 5.1-2, General Plan Policy Consistency Analysis, identifies the City's General Plan policies that are applicable to the proposed Specific Plan and development project. For each listed policy, Table 5.1-2 includes a discussion of potential project consistency/inconsistency with the policy to determine if the proposed Villages of San Jacinto Specific Plan would conflict with the policy and thereby result in an environmental impact. Environmental issues raised in the policy consistency analysis are also addressed in other sections of this EIR and are referenced where relevant.

Table 5.1-2
General Plan Policy Consistency Analysis
Policy Project Consistency
Land Use Element: The Land Use Element is a guide to land use planning within the City of San Jacinto and affects many of the issues addressed in the other General Plan elements. The Land Use Element identifies the type and location of future land uses within the City. The specific land uses and their location within the community in turn affect the remaining General Plan elements. For example, the location and type of land uses outlined in the Land Use Element affect the circulation system that is identified in the Circulation Element, and the allowable density of residential land identified in the Land Use Element affects the Housing Element policies. The land uses identified in the Land Use Element also reflect the community’s goals for its future form and character.

Land Use Policy Goal: Balance of Land Uses – Develop a balanced land use pattern that meets community needs for residential, commercial, industrial, public, and recreational uses.

LU Policy 1.1: Promote a land use composition in
San Jacinto that provides a balance or surplus
between the generation of public revenues and the
cost of providing community services and facilities.

The community provides for a variety of public facilities, including educational, municipal, and recreational land uses, as well as residential land uses. The community also designates approximately 22.7 acres for commercial land uses and 26.3 acres of mixed-use land uses. It is anticipated that these mixed-use and commercial land uses will generate additional revenue streams for the City, including sales tax. In addition, the project will be required to contribute development impact fees to cover its “fair share” cost of providing public services and facilities to the site, including fire protection, police protection, and libraries. As such, the balanced land uses provided by THE VILLAGES OF SAN JACINTO will contribute to public revenues and the project is therefore consistent with, and will result in the implementation of, this General Plan policy.

LU Policy 1.2: Create housing opportunities that
match employment opportunities within the
community.

THE VILLAGES OF SAN JACINTO Specific Plan establishes a high quality, master-planned community that provides for a wide range of residential home product types on lot sizes ranging from 4,000, 5,000, to 6,000 square feet. This variety of lot sizes will result in home sizes designed to appeal to a wide range of potential residents and available in a range of prices.

Policy Project Consistency
Furthermore, THE VILLAGES OF SAN JACINTO combines housing, employment, and retail activities on one site. The community contains a maximum of 1,329 residential units, 22.7 acres of commercial land uses, and 26.3 acres of mixed-use land uses (including commercial, office, retail and municipal uses). This balance of land uses within the community contributes towards a greater balance between jobs and housing within the City. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

LU Policy 1.4: Provide public/institutional land use
designations and development standards that
encourage the location and operation of adequate
public facilities to serve the community.

LU Policy 1.6: Maintain land use designations and
regulations that permit the successful development
and operation of public and private educational
facilities at appropriate locations within the planning area.

THE VILLAGES OF SAN JACINTO provides a 69.1-acre site for use as a High School campus by the San Jacinto Unified School District in Planning Area 14, 40.8 acres of public parks, and the provision of 26.3 acres of mixed-use land uses (which may include public, municipal, and educational uses). Furthermore, this Specific Plan provides for the development of adequate infrastructure (circulation, water, sewer, etc.) necessary to ensure successful implementation of these
public/institutional land uses. Additionally, this Specific Plan provides for amenities, such as landscaping and monumentation, and includes development standards and design guidelines to ensure a high quality of development. Maintenance responsibilities and financing mechanisms also are identified in this Specific Plan to ensure successful long-term operation of these public/institutional land uses. THE VILLAGES OF SAN JACINTO is therefore consistent with these policies.

LU Policy 1.5: Plan and designate adequate open
space and parkland to meet the community's parks,
open space, and recreational needs.

The community’s maximum potential build-out of 1,329 homes would result in approximately 4,000 community residents (at a rate of 3.01 persons per household). The site is planned for a neighborhood park by the General Plan (see Figure CSF-3, Parks and Public Facilities) and per the requirements of the Quimby Act, the community would require approximately 20 acres of active parkland. THE VILLAGES OF SAN JACINTO Specific Plan exceeds this requirement by providing active public park facilities totaling approximately 40.8 acres (Planning Area 15B, 15C, and 15D), in addition to the private recreation facilities and paseos that are provided on 68.7 acres. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

LU Policy 1.3: Attract light industry and other
compatible employment generating businesses.

LU Policy 1.7: Encourage additional retail
development to increase sales tax revenues and
expand the range of services available to the
community.

LU Policy 1.8: Encourage the development of
business parks and office parks to expand the
number and type of job opportunities in San Jacinto.

THE VILLAGES OF SAN JACINTO includes opportunities for a variety of commercial activities that would generate employment and sales tax revenue. Specifically, 22.7 acres of commercial land uses are located within Planning Area 11 in the southeastern portion of the community and provide for neighborhood retail, entertainment, restaurant and employment opportunities. Additionally, a 26.3-acre mixed-use area (Planning Area 12), which allows for retail commercial, entertainment, office, and municipal land uses, is located in the southwestern portion of the community. The land uses permitted in Planning Area 12 create additional employment opportunities. This variety of land uses within the community would create new jobs, increase sales tax revenues for the City, and expand the range of services available to the surrounding area.

THE VILLAGES OF SAN JACINTO is therefore is consistent with these policies.

LU Policy 1.9: Support the provision of outdoor
gathering places such as plazas, greens and
squares to strengthen social interaction and provide

Furthermore, the community features 40.8 acres of public parks containing picnic areas, BBQ pits, benches, tot lots, and other amenities that encourage social interaction. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Land Use Policy Goal: Manage and Direct Growth – Manage and direct growth so that the community and its neighborhoods are protected and enhanced.

LU Policy 2.1: Assure that new development is
complementary to the existing character of the City.

LU Policy 2.2: Encourage infill development to be
consistent with and complement the bulk, scale,
intensity, and character of the existing surroundings.

THE VILLAGES OF SAN JACINTO will develop the site with a similar building scale and development intensity commonly found in the community. The design theme of THE VILLAGES OF SAN JACINTO is based on a contemporary interpretation of historical southern California architectural styles and features a relaxed landscape feel reminiscent of rural communities. The Specific Plan also includes architectural design standards for site planning, architectural theme and details, building mass and scale, materials and color to create a high-quality living environment, as wellcomplement and enhances the existing character of the City and the surrounding community.

LU Policy 2.3: Ensure that development corresponds
to the provision of community services and facilities
and new development funds its share of
improvements (e.g., parks, schools, trails, utilities).

LU Policy 2.4: Ensure that adequate infrastructure
and public services are provided in concert with
development so that no negative fiscal or service
impact occurs as a result of new development.

THE VILLAGES OF SAN JACINTO provides for the development of public parks, public/municipal uses, and a high school. In addition, the community provides for the development of private parks and trails. As described in detail Specific Plan Section IV.7, Project Phasing Plan, THE VILLAGES OF SAN JACINTO provides for the development of infrastructure necessary to service the planned land uses and community facilities.

The community master developer will also be required to pay development impact fees to cover the project’s fair share of community services, including fire protection, police protection, and libraries.

Therefore, THE VILLAGES OF SAN JACINTO is consistent with, and results in the implementation of, this General Plan policy.

LU Policy 2.7: Locate retail and commercial land
uses along major circulation routes at major
intersections where there is maximum access and
visibility.

LU Policy 2.8: Direct higher density housing and
higher intensity employment around commercial
uses and job centers near transit nodes and areas
served by a well-developed transportation network.

THE VILLAGES OF SAN JACINTO includes 22.7 acres of commercial land uses along Bridge Street and Sanderson Avenue. In addition, the community includes 26.3 acres of mixed-use land uses along Bridge Street at the planned extension of Cawston Avenue. Bridge Street acts as a major circulation axis between Sanderson Avenue and Cawston Avenue, and will facilitate efficient access to-and-from the site for patrons and employees, while providing maximum visibility; therefore, ensuring consistency with this policy.

It is important to note that the General Plan anticipates that community commercial land uses would be developed on the project site, immediately adjacent to Sanderson Avenue, as depicted on Figure III-2, General Plan Map. The project accommodates the commercial uses anticipated by the General Plan, but locates these uses at the southern portion of the site, along Bridge Street (as described above). The layout of mixed-use and commercial land uses planned by THE VILLAGES OF SAN JACINTO is preferred in lieu of the layout identified in the General Plan, as it provides a buffer between the EMWD wastewater treatment plant immediately adjacent to the southern site boundary and the open space and residential uses planned by the project.

Policy Project Consistency
LU Policy 2.9: Where feasible and beneficial to the
City and its residents, encourage the joint use of
public facilities.

The project includes accommodations for a variety of public facilities (including a high school, public parks, and other municipal uses). The location of these planned uses within the community and their proximity to complementary uses, such as residential and commercial land uses, promotes the joint use of these facilities. Consequently, THE VILLAGES OF SAN JACINTO is consistent with this policy.

Land Use Policy Goal: Environmental Compatibility – Foster development in San Jacinto that ensures the compatibility of land uses with environmental conditions.

LU Policy 3.1: Limit development in the hillsides,
ridgelines, floodplains, and other high risk areas.

LU Policy 3.4: Preserve prominent ridgelines by
restricting development on slopes of 40% or higher.

As discussed in Specific Plan Section III.B, Environmental Setting, the site is relatively flat and slopes gently to the northwest; no prominent slopes, hillsides or floodplains exist on-site. The northerly portion of the site is located within the 100-year floodplain. The drainage system (refer to Specific Plan Section IV.3, Drainage Plan) has been designed to convey and attenuate 100-year storm flows and provide flood protection for the site. A complete, detailed discussion of potential adverse impacts associated with 100-year storm flows is contained in the EIR accompanying this Specific Plan. As concluded in the EIR, with the incorporation of design measures and mitigation – as needed – implementation of the project will not result in substantial risk to humans or structures.

LU Policy 3.2: Explore methods to preserve areas of
severe natural hazards, such as landslides, ground
subsidence, liquefaction, and flooding as open
space.

As discussed in the EIR that accompanies the specific plan for THE VILLAGES OF SAN JACINTO, and as indicated in the Specific Plan, earthquake faults do traverse portions of the site. However, as shown on Figure III-6 of the Specific Plan, Structural Setbacks, the site has been designed to preserve areas located in the identified fault zone as recreational open space. As discussed above, the site is not subject to substantial adverse effects related to flooding. Accordingly, THE VILLAGES OF SAN JACINTO is consistent with this policy.

LU Policy 3.3: Permit the joint-use of preserve areas
and easements such as seismic faults and drainage
basins for open space and recreational uses.

A portion of the Casa-Loma segment of the San Jacinto Fault Zone Complex traverses a portion of the site. The fault segment and the surrounding fault zone buffer is inappropriate for development of residential uses or habitable structures. THE VILLAGES OF SAN JACINTO utilizes a majority of the fault zone area for active and passive recreational uses, site drainage, and internal circulation and is consistent with this policy.

Land Use Policy Goal: Land Use and Circulation Compatibility – Promote high quality development that ensures compatibility with surrounding land uses and major transportation corridors.

LU Policy 4.1: Evaluate the compatibility of new
development with surrounding uses when reviewing
development proposals and designing the circulation
system improvements.

LU Policy 4.2: Ensure that new development is
compatible with the physical characteristics of the
site, surrounding land uses, and available public
infrastructure.

THE VILLAGES OF SAN JACINTO will result in the development of the site with a mix of land uses consistent with the General Plan land use designations for the site. The land uses on-site will be developed with a similar building scale and development intensity commonly found in the surrounding community. Development on-site will be required to be consistent with Section V, Design Guidelines, of THE VILLAGES OF SAN JACINTO, which includes architectural design standards for site planning, architectural theme and details, building mass and scale, materials and color to create a high-quality living environment. In addition, as described in Specific Plan Section III, THE VILLAGES OF SAN JACINTO provides adequate circulation and infrastructure improvements to accommodate development of the site.

LU Policy 4.3: Maximize commercial, retail, and
employment opportunities along the City’s major
corridors and intersections, including SR-79, the
Ramona Expressway, Sanderson, and Cottonwood.

As discussed above in the response to General Plan policy 2.7, THE VILLAGES OF SAN JACINTO Specific Plan provides 22.7 acres of commercial land uses and 26.3 acres of mixed-use adjacent to major circulation corridors. The location of mixed-use and commercial land uses along major circulation corridors will maximize visibility of these land uses and will provide site patrons and employees with adequate, efficient circulation to-and-from the site.

LU Policy 4.4: Ensure new development provides
roadways that meet the City’s standards based on
the classifications shown in the Circulation Master
Plan and the level of traffic expected to be generated
by the proposed project.

THE VILLAGES OF SAN JACINTO Specific Plan includes a roadway network which provides safe and efficient circulation to individual planning areas and land uses. The Specific Plan includes full- and half-width improvements to the following General Plan Circulation Element roadway segments on-site: Sanderson Avenue, De Anza Drive, Bridge Street, Odell Avenue, Cawston Avenue, and Ramona Boulevard. In addition, the project provides for the construction of on-site local roads.

All roadways improvements will be constructed to meet City of San Jacinto standards. The community’s Circulation Plan, conceptually illustrated on Figure IV-2, Project Circulation Plan.

The EIR that accompanies THE VILLAGES OF SAN JACINTO Specific Plan evaluates traffic and circulation impacts that may occur upon implementation of this project and provides mitigation measures to reduce identified impacts to a level below significance, when feasible.

The Planning Commission and City Council will review the EIR to ensure adequate provision of circulation facilities.

Therefore, THE VILLAGES OF SAN JACINTO Specific Plan is consistent with, and results in the implementation of, this policy of the General Plan.

LU Policy 4.5: Minimize the number of vehicular
access points on major corridors by using reciprocal
access agreements whenever feasible.

As depicted on Specific Plan Figure IV-2, Project Circulation Plan, the project has been designed to minimize vehicular access points on major circulation corridors, including Sanderson Avenue.

LU Policy 4.6: Enhance pedestrian access both
within shopping centers and to and from commercial
uses to reduce vehicle trips generated within the
City.

Section V, Design Guidelines, requires that structures within Planning Area 11 (Neighborhood Commercial) and Planning Area 12 (Mixed Use Commercial) be oriented in a pedestrian-friendly manner to take advantage of park views. The commercial land uses are required to provide either street-facing entrances and/or entrances that are easily accessed from the park and parking areas. The scale of the buildings and plan are pedestrian-friendly and encourage pedestrian activity between structures. The design principles set forth in Section V, Design Guidelines, requires major projects or individual buildings at key locations within the commercial area to incorporate public plazas at focal points and at activity centers. Furthermore, parking lots within the commercial area shall be pedestrian-friendly in nature, with walkways provided in appropriate locations. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Land Use Policy Goal: Resource Preservation – Preserve and protect the City’s cultural, historic, agricultural, and visual resources.

purposes throughout the City.

THE VILLAGES OF SAN JACINTO Specific Plan includes an extensive set of landscape design guidelines to ensure the community is developed with a cohesive theme that weaves together the residential, recreational, and other components of the community. The landscape design guidelines include provisions for streetscapes, edge conditions between uses, monumentation and community walls and fences, as well as provisions to screen incompatible uses. In addition, the Specific Plan includes guidelines for site design and landscaping and provides solar control and maximizes energy efficiency (see Specific Plan Section V.E., Energy Efficiency Guidelines. Therefore, THE VILLAGES OF SAN JACINTO Specific Plan is consistent with this General Plan policy.

LU Policy 6.4: Encourage outdoor gathering spaces,
such as mini-parks and plazas that encourage social
interaction and also enhance the visual character of
the community.

The land use plan for THE VILLAGES OF SAN JACINTO includes numerous outdoor gathering spaces, including public community parks, private paseos, a private lake, and a private lake house and swim lagoon.

These outdoor spaces will include passive and active recreational opportunities, picnic areas, BBQ pits, benches, tot lots, landscaping and other amenities that encourage social interaction (as described in Specific Plan Section V, Design Guidelines).

LU Policy 6.5: Encourage the use of project design
features that reduce impacts to important and local
regional environmental resources.

THE VILLAGES OF SAN JACINTO has been carefully planned to minimize impacts to important environmental resources. The drainage plan for the project has been designed to minimize water quality impacts and maximize protection from flood flows; the landscape plan has been designed to maximize water conservation. In addition, the lake on-site will contain recycled water and will be used to irrigate on-site landscaping, further reducing the impact on the water supply.

The EIR that accompanies THE VILLAGES OF SAN JACINTO Specific Plan includes a detailed evaluation of the project’s potential to result in significant direct and/or indirect impact to the environment impacts. The EIR includes mitigation measures that will be required in order to reduce impacts to below a level of significance, when feasible. The Planning Commission and City Council will review the EIR to ensure adequate protection of environmental resources.

Accordingly, THE VILLAGES OF SAN JACINTO is consistent with this General Plan policy.

LU Policy 6.10: Promote the maintenance of private

protection design features (e.g., fire lanes) will be identified on future site plans and/or conditional use permits and are subject to review and approval by the City of San Jacinto. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Community Services and Facilities Goal: Public Education – San Jacinto is located within the San Jacinto Unified School District (SJUSD) and the Hemet Unified School District (HUSD). Mount San Jacinto College (MSJC) is also located within the City. The City must closely coordinate with SJUSD, HUSD, and MSJC to ensure a sufficient level of public education is available to the community.

CS&F Policy 3.2: Promote the development and
siting of quality educational facilities to meet the
needs of future residents through increased
cooperation between the City and school districts.

THE VILLAGES OF SAN JACINTO provides a 69.1-acre site for use as a High School campus by the San Jacinto Unified School District in Planning Area 14 and allows for possible expansion of the High School campus into Planning Area 19. Additionally, THE VILLAGES OF SAN JACINTO Specific Plan permits the development of Planning Areas 12 and 13 as school sites. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

CS&F Policy 3.5: Minimize the impacts of schools on
adjacent properties.

Section V, Design Guidelines, of THE VILLAGES OF SAN JACINTO Specific Plan includes design guidelines for transitions between various types of land uses, including residential and public facility/educational uses. The intent of these guidelines are to anticipate and eliminate possible conflicts between land uses. Future development of the site will be required to be consistent with the design guidelines for land use transitions, thus ensuring that impacts of schools on adjacent properties are minimized.

Community Services and Facilities Goal: Water Service – Work with local, regional, and State water agencies to provide sufficient levels of water service.

CS&F Policy 4.1: Provide sufficient levels of water
service to meet the water needs of the community
through the orderly extension of infrastructure and
provision of adequate water supplies.

CS&F Policy 4.2: Work closely with the Eastern
Municipal Water District and the Lake Hemet
Municipal Water District to maintain an adequate
level of water service in the planning area.

The Eastern Municipal Water District (EMWD) has prepared a Water Supply Assessment report for the project. The report concludes that EMWD is projected to have adequate water supply to service the project.

In addition, the project would minimize its demand for water supplies through the extensive use of recycled water for landscape irrigation; the use of drought-tolerant, native landscape materials; the recommended use of water-efficient faucets, toilets, and shower heads; and the recommended use of water-efficient, zoned irrigation systems. A detailed discussion of the project’s impacts to the local water supply is found in the EIR that accompanies THE VILLAGES OF SAN JACINTO Specific Plan.

The master water plan for the community provides a water distribution system that is based on EMWD requirements and will adequately serve the community in a manner consistent with the EMWD Northwest San Jacinto Area Master Plan.

Based on the foregoing, THE VILLAGES OF SAN JACINTO is consistent with these General Plan policies.

CS&F Policy 4.3: Encourage water conservation as
a means of preserving water resources.

Community Services and Facilities Goal: Sewer Service – Work with the Eastern Municipal Water District to provide a wastewater collection, treatment, and disposal system to adequately serve existing and future development in San Jacinto.

CS&F Policy 5.3: Ensure compatible development
occurs surrounding the San Jacinto Waste Water
Treatment Facility.

THE VILLAGES OF SAN JACINTO has been carefully designed and planned to ensure that development on-site is compatible with the San Jacinto Waste Water Treatment Facility, which is located immediately adjacent to the southern project boundary. The mixed-use and commercial land uses (Planning Areas 11 and 12) buffer the community from the Waste Water Treatment Facility and complement the residential and recreational components of the community. In addition, three public parks (Planning Areas 15B, 15C, and 15D) provide an additional buffer between the off-site Waste Water Treatment Facility and planned residential uses. Accordingly, implementation of THE VILLAGES OF SAN JACINTO Specific Plan would ensure that compatible development occurs adjacent to the Waste Water Treatment Facility and would ensure that community residents are not exposed to adverse edge-effects. As such, the project is consistent with this General Plan policy.

CS&F Policy 5.4: Encourage water conservation as
a means of reducing sewage generation.

THE VILLAGES OF SAN JACINTO encourages the use of water-efficient faucets, high-efficiency toilets, and water conserving shower heads to maximize water conservation and reduce sewage generation. The project encourages the use of a pool filtration system with a zero water backwash system to reduce the need to drain the pool for regular maintenance purposes. In addition, as described in Section V, Design Guidelines, the plant palette for the project has been designed to feature native or naturalized, drought-resistant plant material, and the conceptual landscape design will minimize the use of turf. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

CS&F Policy 5.5: Expand the use of reclaimed
water.

As shown in Figure IV-5, Master Water Plan, recycled water pipelines will be installed concurrently with domestic lines. The water from this recycled water system will be used to maintain the lake volume and provide water storage for irrigation purposes. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

CS&F Policy 5.6: To reduce potential negative
impacts to groundwater, minimize the use of septic
systems.

THE VILLAGES OF SAN JACINTO Specific Plan does not provide for the use of septic systems on site. Wastewater generated by the community will conveyed via a sanitary sewer system to existing EMWD sewer facilities, as described in Specific Plan Section 4.B, and conceptually illustrated in Figure IV-6, Master Sewer Plan.

CS&F Policy 8.1: Ensure that adequate flood control
facilities are provided to protect the lives and
property of San Jacinto's residents.

As described in THE VILLAGES OF SAN JACINTO EIR, the community provides for adequate flood control facilities. Furthermore, a portion of the regional area drainage plan, the San Jacinto Valley Master Drainage Plan, traverses THE VILLAGES OF SAN JACINTO community along its western boundary. The community design acknowledges and accommodates these regional drainage facilities, utilizing a series of storm water channels, water quality control basins, and detention basins to collect and transport stormwater through the site. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Community Services and Facilities Goal: Waste Disposal – Work effectively with providers of waste disposal to provide sufficient levels of these services.

CS&F Policy 9.1: Reduce the amount of solid waste
requiring disposal at landfills.

Section V, Design Guidelines, includes detailed Energy Efficiency Guidelines that identify elements in the site planning, design and construction phases of this Specific Plan that can and should be implemented to achieve a standard of energy efficient performance which is desirable for the homeowner, the landlord, the environment, and builder/developer. Included within the Energy Efficiency Guidelines are specific recommendations to minimize the amount of landfill waste generated by the project, including the use of long-lasting construction products (for example, engineered lumber) and sustainable building materials. In addition, THE VILLAGES OF SAN JACINTO Specific Plan encourages the provisions of exterior storage areas for recyclables and adequate recycling containers in public areas, in addition to the establishment (by the HOA) of community compost sites for green waste. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Community Services and Facilities Goal: Recreation and Open Space – Provide sufficient parks, recreational, and open space facilities.

CS&F Policy 10.1: Work with the Valley-Wide
Recreation and Park District and other organizations
to provide active and passive parks, recreational,
and open space facilities that meet the needs of all
segments of the community.

The community’s maximum potential buildout of 1,329 dwelling units would result in approximately 4,000 community residents (at a rate of

3.01 persons per household). Per the requirements of the Quimby Act, the community would require approximately 20 acres of active parkland.

THE VILLAGES OF SAN JACINTO Specific Plan exceeds this requirement by providing an extensive paseo and trail system and 40.8 acres of active public park facilities (Planning Area 15B, 15C, and 15D). In addition to the public parks, paseos, and trails, the community includes a 1.0-acre private neighborhood park (Planning Area 15A), a 1.2-acre private neighborhood park (Planning Area 15E), and a private 5.1-acre Lake

of equestrian, biking, and hiking trails that link to
adjacent regional and local trails networks.

THE VILLAGES OF SAN JACINTO links the residential, commercial, recreational, mixed-use, and school land uses via a 9.6-acre system of paseos, which connects to city sidewalks. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

CS&F Policy 10.3: Use flood control facilities for
passive recreational activities when appropriate.

Flood control facilities, including drainage channels and detention basins, have been incorporated into the design of the project (Planning Areas 18A-18D). The flood control facilities provided on-site are not considered appropriate for recreational activities. As such, THE VILLAGES OF SAN JACINTO is consistent with this General Plan policy.

CS&F Policy 10.4: Encourage the joint use of City
and other public agency facilities for recreational
purposes, education, and flood control whenever
feasible.

THE VILLAGES OF SAN JACINTO provides for a high school campus and a mixed-use area (which may accommodate public/municipal/ institutional land uses). The distribution of these land uses adjacent to recreational and residential uses promotes the joint use of public facilities.

CS&F Policy 10.5: When feasible, use less
developable or undevelopable lands, including utility
corridors, fault zones, channels, and easements for
passive and active recreational uses that have
minimal potential for impacts on the environment.

The project site contains a portion of the Casa-Loma segment of the San Jacinto fault zone project. The fault segment and the surrounding fault zone buffer are inappropriate for development with residential uses or habitable structures. THE VILLAGES OF SAN JACINTO utilizes a majority of the fault zone area for active and passive recreational uses, flood control facilities, and internal circulation – uses that have a minimal potential for impacts on the environment or residents/visitors of the site. Accordingly, the project is consistent with this General Plan policy.

CS&F Policy 10.6: Encourage the development of

Public Safety Goal: Natural Hazards – Minimize the risk of injury and the loss of life and property related to geologic conditions, seismic activity, wildfires, and flooding.

PS Policy 1.1: Reduce the risk of impacts from
geologic and seismic hazards by applying proper
and up to date land use planning, development
engineering, building construction, and retrofitting
requirements.

In addition, a geotechnical engineering report was prepared for the project and is discussed in the EIR that accompanies THE VILLAGES OF SAN JACINTO Specific Plan. Mandatory compliance with the design recommendations included within the project geotechnical report, State building code, and City of San Jacinto building requirements will ensure that adverse impacts related to geologic and seismic hazards will be reduced to the maximum feasible extent.

Accordingly, implementation of the project is consistent with this General Plan policy.

PS Policy 1.2: Encourage landscaped open space
uses for areas within identified fault zones, and
prohibit residential development in these areas.

As described in the geotechnical report prepared by Leighton & Associates for THE VILLAGES OF SAN JACINTO EIR, a California Earthquake Fault Hazard Zone traverses several portions of the project.

Based on analysis of the fault trace and disturbance zones, the report recommended structural setback limits from faults for residential development. These setback criteria were utilized during the design process, resulting in parks provided on the portions of the project where faults exist. THE VILLAGES OF SAN JACINTO is therefore is consistent with this policy.

PS Policy 1.5: Protect the community from flooding
hazards by providing and maintaining flood control
facilities and limiting development within the flood
plain.

The northerly portion of the site is located within the 100-year floodplain.

The drainage system (refer to Specific Plan Section IV.3, Drainage Plan) has been designed to convey and attenuate 100-year storm flows and provide flood protection for the site. A maintenance plan has been established in THE VILLAGES OF SAN JACINTO Specific Plan to ensure that on-site drainage facilities operate at maximum efficiency. A complete, detailed discussion of potential adverse impacts associated with 100- year storm flows is contained in the EIR accompanying this Specific Plan. As concluded in the EIR, with the incorporation of design measures and mitigation – as needed – implementation of the project will not result in substantial adverse impacts related to flood hazards.

Public Safety Goal: Human Activity Hazards – Protect the community from hazards related to air pollution, dam inundation, hazardous materials, structural fires, ground transportation, and criminal activity.

PS Policy 2.6: Provide sufficient levels of police, fire, and emergency response service to reduce the risk
of criminal activity.

Upon ultimate development of the site, the master developer of THE VILLAGES OF SAN JACINTO will be required to contribute development impact fees to cover its “fair share” cost of providing sufficient public services and facilities to the site, including fire protection, police protection, and emergency response service. The project is therefore consistent with this General Plan policy.

PS Policy 2.7: Ensure projects include design
features that promote safety and reduce criminal
activity.

THE VILLAGES OF SAN JACINTO Section V, Design Guidelines, includes numerous design features that promote safety and reduce criminal activity. These design features include special considerations for the siting of paseos and cul-de-sacs, the potential use of locked key or card gates at paseo/park connections, the lighting of house numbers, the orientation of alley-loaded or rear-load homes towards the adjacent paseo area, and more. Homes shall be oriented to face park areas, and to fencing material shall be careful selected to ensure maximum visibility of the park from public areas. Common parking areas within the commercial, mixed-use, park, and school areas shall be well-lit for security purposes. THE VILLAGES OF SAN JACINTO is therefore consistent with this policy.

Noise Element: The Noise Element addresses noise sources in the community and identifies ways to reduce the impacts of these noise sources. The Noise Element contains policies and programs to achieve and maintain noise levels compatible with various types of land uses. The Element identifies those land uses that are sensitive to noise and assures that noise-generating land use are located so that they do not impact those sensitive areas.

Noise Goal: Noise and Land Use Planning – Minimize the effects of noise through proper land use planning and development techniques.

N Policy1.1: Use the City’s adopted noise/land use
compatibility standards as a guide for future planning
and development decisions.

N Policy 1.2: Require noise control measures, such
as berms, walls, and sound attenuating construction
in areas of new development or rehabilitation.

N Policy 1.3: When necessary, require buffer areas
between noise sources and sensitive receptors.

N Policy 1.4: Use creative techniques to mitigate
potential noise incompatibilities, particularly in areas with a mixture of uses.

THE VILLAGES OF SAN JACINTO incorporates several design elements to minimize noise impacts on sensitive receptors. A buffer is provided along Sanderson Avenue to minimize effects of traffic related noise on community residents, and on-site residential uses are buffered from the off-site Waste Water Treatment Facility and on-site mixed-use and commercial land uses.

A noise analysis was conducted for THE VILLAGES OF SAN JACINTO and is summarized in the EIR accompanying this Specific Plan. As described in the EIR, this analysis evaluated potential noise impacts and provided mitigation to reduce levels to below the required CNEL for residential and non-residential land uses. With incorporation of these mitigation measures, no significant noise impacts will result upon implementation of THE VILLAGES OF SAN JACINTO, and the project is therefore consistent with this policy.

Noise Goal: Transportation Related Noise – Minimize the effects of transportation-related noise.

N Policy 2.1: Reduce transportation-related noise
impacts to sensitive land uses through the use of
noise control measures.

N Policy 2.2: Require sound-reduction design in
development projects impacted by transportationrelated noise, particularly along highways and major arterials.

Where appropriate and necessary, THE VILLAGES OF SAN JACINTO provides buffers to minimize transportation-related noise impacts to sensitive land uses. In addition, the Specific Plan establishes planning and site design criteria that would result in the reduction of unwanted sound, to the maximum feasible extent. As described in detail in the EIR accompanying THE VILLAGES OF SAN JACINTO Specific Plan, a noise analysis was prepared for the project and provided mitigation to reduce levels to acceptable levels for sensitive uses. With mandatory compliance with these mitigation measures, no significant noise impacts will result upon implementation of THE VILLAGES OF SAN JACINTO, and the project is therefore consistent with this policy.

Housing Element: The Housing Element is a guide for housing within the City of San Jacinto. The Element provides an indication of the need for housing in the community in terms of affordability, availability, adequacy, and accessibility. The Element provides a strategy to address housing needs and identifies a series of specific housing programs to meet community needs. A detailed Housing Needs Assessment was prepared as part of the Housing Element update and serves as the technical background document to the Housing Element.

Housing Goal: Provide Adequate Housing Sites – Provide Adequate sites for new residential construction to meet the needs of all segments of the community without compromising the character of the City.

Housing Goal: Assist in Development of Housing – Assist in the development of a housing supply which is affordable to all segments of the community.

H Policy 2.2: Provide adequate sites for a range of
housing types and prices.

H Policy 3.1: All for the development of housing
affordable to all income groups by utilizing a variety
of public and private efforts.

H Policy 3.3: Promote the development of attractive
and safe housing to meet community needs.

THE VILLAGES OF SAN JACINTO provides for a maximum of 1,329 homes in a variety of residential product types and styles and home sizes, including single-family homes on 4,000 s.f., 5,000 s.f., and 6,000 s.f. lots.

This variety of residential housing products would appeal to homebuyers of different incomes and family sizes. These homes would be required to conform to the Design Guidelines included in Section V, ensuring the development of an attractive and safe community. THE VILLAGES OF SAN JACINTO is therefore is consistent with this policy.

City of San Jacinto Zoning Ordinance
The proposed Specific Plan includes a zone change for the property which would result in removing the existing C-2, R-1, R-2 (PUD) and R-3 zoning designations and application of a Specific Plan zoning designation to the entire site. The Villages of San Jacinto Specific Plan is generally consistent with the provisions of the General Plan and Zoning Ordinance which require initiation of Specific Plans for large-scale planned development. When adopted by legislative action, the Specific Plan document will serve both planning and regulatory functions for the proposed development. The intent of the Specific Plan zoning designation is to establish base zoning and applicable development standards specific to the defined project area to direct new growth and development in the process of implanting the General Plan. Adopted Specific Plan zoning and development standards will take precedence over the general standards of the Zoning Ordinance, except where the Specific Plan does not contain an applicable development standard, in which case the standards of the Zoning Ordinance apply.

Transportation Uniform Mitigation Fee 10-Year Strategic Plan (TUMF) The WRCOG is a council which is comprised of members representing 15 local jurisdictions in western Riverside County, including the City of San Jacinto. The WRCOG functions to facilitate collective assessment of regional issues, such as traffic, by the various representative jurisdictions. In June 2004, WRCOG adopted the TUMF 10-Year Strategic Plan and Transportation Improvement Program Development Guidelines.

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-37
The purpose of the TUMF program is to establish a comprehensive funding source for infrastructure improvements to mitigate cumulative regional transportation impacts of new development on regional arterial highways (Parsons Brinckerhoff Quade & Douglas, Inc. 2004).

The WRCOG has developed and implemented the TUMF program which requires new development to contribute revenues to partially fund improvements that will mitigate the transportation impacts of new developments. The proposed project would be required to contribute funds to the TUMF program based on the proposed number of residential dwelling and the applicable defined residential land use fee rate to ensure project compliance with the program. Additional discussion of the proposed project's compliance with applicable TUMF program requirements is included in Section 5.9, Transportation, Circulation, and Access.

South Coast Air Quality Management Plan
The South Coast Air Quality Management District Governing Board adopted the 2003 Air AQMP on August 1, 2003, and adopted the 2007 AQMP on June 1, 2007. The 2003 AQMP updates the attainment demonstration for the federal standards for O3 and PM10; replaces the 1997 attainment demonstration for the federal CO standard, provides a basis for a maintenance plan for CO for the future; and updates the maintenance plan for the federal NO2 standard that the SCAB has met since 1992. The 2007 AQMP includes the same updates as the 2003 AQMP and also incorporates significant new scientific data, primarily in the form of updated emissions inventories, ambient measurements, new meteorological episodes and new air quality modeling tools. As part of the 2007 AQMP, the SCAQMD request that EPA "bump up" the O3 nonattainment status from severe to extreme to allow additional time for the SCAB to achieve attainment with the federal standard. The additional time would provide for implementation of state and federal measures that apply to sources over which the SCAQMD does not have control.

The 2007 AQMP has been approved by CARB but is undergoing review by EPA.

Additional discussion of potential project air quality impacts and applicable AQMP program requirements is included in Section 5.10.

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01

Would the project conflict with any applicable habitat conservation plan or natural community conservation plan?
Western Riverside County Multiple Species Habitat Conservation Plan The Western Riverside County MSHCP is a comprehensive, long-term habitat conservation program which addresses the needs of a variety of biological resources. The primary goal of the MSHCP is to develop and manage sustainable preserve areas within existing and expanding urban areas. The preserve areas and management efforts contained in the final MSHCP will affect land use planning in the entire City of San Jacinto area. Section 5.4, Biological Resources, provides an in depth discussion of the project's relationship and consistency with the Western Riverside County MSHCP.

Would the project introduce a land use that is incompatible with existing or proposed surrounding land uses?
The proposed project would potentially result in significant urban/rural land use conflicts between the planned residential, commercial and mixed use development and existing agricultural uses surrounding the project site. Such conflicts could include fertilizer and pesticides application drift into the proposed residential area, residential complaints about noise and dust resulting from site preparation activities associated with adjacent agricultural activities, and increased trespassing onto agricultural lands. Additional discussion of potential project impacts associated with rural agricultural and urban residential land use conflicts is included in Section 5.3, Agricultural Resources.

Development of the proposed Villages of San Jacinto Specific Plan area is located immediately adjacent to the Hemet/San Jacinto Regional Water Reclamation Facility currently owned and operated by the Eastern Municipal Water District (EMWD). New residential development located near industrial-type facilities such as the wastewater treatment plant can result in potentially significant land use conflicts derived from residential complaints about noise and odors generated from plant operations. However, the proposed Specific Plan would designate land directly adjacent to the wastewater treatment facility as commercial and mixed-use business park. The commercial and mixed-use areas are buffered from on-site residential land uses by parks and intervening roadways. The nearest residential lots to the treatment plant would be located over 1,000 feet from the plant boundary. As such, the proposed Villages of San Jacinto development incorporates buffers into the development to minimize potential land use impacts between the proposed residential, commercial development, and the adjacent wastewater treatment facility. Additional discussion of potential land use conflicts associated with plant operation odors is included in Section 5.10, Air Quality, and plant operation noise is included in Section 5.11, Noise. Noise impacts potentially associated with traffic generated by the project are

5.1 LAND USE, PLANNING, AND ZONING
Villages of San Jacinto EIR 4307-01
August 2009 5.1-39
not expected to result in significant noise impacts along access roads to and within the project area, as described in Section 5.11.

5.1.5 Mitigation Measures
The proposed project would not divide an established community or conflict with applicable plans, policies or regulations including the Western Riverside Multiple Habitat Conservation Plan. Therefore, no mitigation is proposed for these issues. Mitigation is provided in Section 5.2, Landform Alteration and Aesthetics, and Section 5.11, Noise, which requires notification of homeowners in the vicinity of the school site that there may be lighting impacts and noise associated with outdoor activities in the future should the school district proceed with plans for the proposed high school. Additionally, mitigation requiring notification for potential urban/rural land use conflicts between the project and existing agricultural uses is provided in Section 5.3, Agricultural Resources .

5.1.6 Residual Impacts/Level of Significance after Mitigation Land use and planning impacts, outside of those related to noise, aesthetics, and agricultural resources (as indicated above in Section 5.1.5), have not been identified, therefore mitigation measures are not necessary.

5.2 LANDFORM ALTERATION AND AESTHETICS

5.2.1 Introduction and Methodology
This section addresses the potential for the Villages of San Jacinto project to produce visual impacts or affect visual character upon implementation. The analysis primarily focuses on the large-scale configuration and distribution of land use types on the site, and architectural/design standards of the Specific Plan.

Existing visual conditions were compiled through a site visit and review of aerial photographs.

Public vantage points near the proposed project site were identified and the existing visual character summarized. Analysis of impacts is based on an assessment of how the view would change in addition to an assessment of the project's compliance with viewshed and other aesthetic policies in the City's General Plan.

5.2.2 Existing Conditions
Existing Setting
The project site is located in the San Jacinto Valley. The San Jacinto Valley is a northwest/southeast trending geographic feature formed by an "elbow" in the San Jacinto Mountain Range. The face of the San Jacinto Range faces southwest along the easterly side of San Jacinto Valley; at the southern end of the San Jacinto Valley near the town of Hemet, the San Bernardino range swings westward and the face of the range is oriented northwest. On the westerly side of the San Jacinto Valley, the valley is defined by the Lakeview Mountains and Bernaconi Hills. Vistas of the surrounding mountain ranges are essentially available in all directions within San Jacinto and are an important component of the regional aesthetic landscape. The San Jacinto River flows in a generally northwest to southeast direction approximately 1.5 miles north of the project site. This river is a dry wash during most of the year except for short periods following substantial rainfall or snowmelt occurring in the San Jacinto Mountains. The river course is not visible from the project site.

The project site is oriented with a long axis approximately north/south. The project site is essentially flat with surface elevation ranging from approximately 1,455 feet above mean sea level (AMSL) along the northern edge to approximately 1,490 feet AMSL in the southeastern corner. By contrast, Mt. Rudolph (the highest peak in the Lakeview Mountains west of the site) is at elevation 2,649 AMSL. The Bernaconi Hills have a peak elevation of approximately 2,100 feet AMSL; Mt. Edna (a part of the San Bernardino Range north of the project) is at elevation 2,587 AMSL; San Jacinto Peak towers above the valley floor at approximately 10,830 feet AMSL. Given the elevation difference between the ground surface at the site and surrounding mountain features, background mountain views are currently available across the subject site

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-2
from the public roadways surrounding the site. Existing views from surrounding roadways are discussed in greater detail in the sub-section below.

Existing Visual Quality of Project Site
The visual character of the site itself can be described as primarily vacant, former agricultural land. Vegetation on site consists of weedy invasive species or natural vegetation that has accumulated since the majority of agricultural production was discontinued. Existing on-site improvements and activities include covered shade structures as part of a former cattle feed lot in the southern portion of the property, an abandoned house and scattered debris in the southcentral portion of the site, primarily fallow field along the eastern property boundary, and scattered sod fields in the northern portions of the property. The aesthetic quality of the site itself would be considered low for the portions containing structural development and moderate for the cultivated agricultural portions of the site. However, as shown in the site photos below, cultivated agriculture is not highly visible from adjacent roadways.

The site is essentially flat and there are no unique visual resources on site, such as tree stands, rock outcrops or water bodies. Therefore there are no current landforms of visual significance that exist on the site.

Figures 5.2-1 through 5.2-6 depict the existing visual quality of the project site as well as existing mountain views available from within and adjacent to the site.

Existing Views
The project site is generally visible from three existing primary viewpoints within the City of San Jacinto, each associated with a roadway. The project site is not visible from any existing roadway facility to the south of the subject site. Sanderson Avenue (east), Ramona Expressway (north), and Warren Avenue (west) each provide existing view opportunities of the project site.

Each of the existing views described below are illustrated in Figures 5.2-2 to 5.2-6.

Sanderson Avenue is currently a heavily traveled regional roadway facility oriented north/south and located along the east side of the subject property. The roadway is at the same elevation as the site and views of the site are directly available to drivers on this roadway. The posted speed is 55 MPH and the site is approximately 6,000 feet (or roughly 1 mile) long; mobile viewers therefore have approximately 1 minute of exposure to direct views of the site along Sanderson Avenue when driving at the posted speed limit. Clearly visible elements of the property's visual character from this vantage (Figures 5.2-2 and 5.2-3) include covered shade structures associated with the former feed lot, an abandoned house to the west of former feed lot, and fallow agricultural land in the foreground with mountain vistas in the background to the west and north.

Ramona Expressway is currently a heavily traveled regional roadway facility oriented roughly east/west and located approximately one half mile to the north of the project's northern property boundary. At this vantage distance, the site is primarily a component of the background vista which is subordinate to the mountains (San Jacinto Range). The posted speed is 65 MPH and the site is approximately 4,800 feet wide; mobile viewers therefore have approximately 1 minute of exposure to distant views of the site along Ramona Expressway while driving at the posted speed limit (Figure 5.2-5). The existing on-site structures are barely visible from this vantage point, and would probably not be noticed by a mobile viewer.

Warren Avenue is currently a heavily traveled regional roadway facility oriented north/south and located approximately one half mile to the west side of the subject property. At this vantage distance, the site is again primarily a component of the background vista, which is subordinate to the mountains (San Bernardino Range and San Jacinto Mountains). The posted speed is 45 MPH and the site is approximately 6,000 feet (or roughly one mile) long; however, structures on the property immediately adjacent to the west side of the project site occupy about two thirds of the length of the project site. Therefore, distant views from Warren Avenue to the site are available roughly along the southern-most 2,000 feet of the property. This one glimpse of the site, at 45 MPH would equate to about 0.5 minute for the mobile viewer (Figure 5.2-6). The existing improvements on the property (i.e., covered shade structures and abandoned house) are barely visible and are completely subordinate to the background mountain views.

Figure 5.2-4 depicts an internal view from the northwest corner of the subject property facing east. Primary views from this location include fallow agricultural land in the foreground; sod fields that can be seen in the mid-foreground, scattered in the distance adjacent to Sanderson Avenue; and the dominant view is of the San Jacinto Mountains in the background.

Applicable Visual Policies
City of San Jacinto General Plan
The current City of San Jacinto General Plan was adopted May 4, 2006. The General Plan is the primary long-range planning document that guides growth and development in San Jacinto.

There are a number of goals and policies in the Land Use Element and Resource Management Element that are relevant to visual resources as described below.

Land Use Element
The following goals and policies relate to maintaining and enhancing the visual character of the community and surrounding scenic vistas.

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-16
Land Use Goal 2 Manage and direct growth so that the community and its neighborhoods are protected and enhanced.

Policy 2.1 Assure that new development is complementary to the existing character of the City.

Policy 2.7 Locate retail and commercial land uses along major circulation routes at major intersections where there is maximum access and visibility.

Land Use Goal 6 Preserve and protect the City's cultural, historic, agricultural, and visual resources.

Policy 6.7 Preserve and enhance public views of the mountains and hillsides and other scenic vistas.

Policy 6.10 Promote the maintenance of private and public properties to enhance the visual appearance of the community.

Land Use Goal 9 Encourage thoughtful community design that enhances San Jacinto's quality of life.

Policy 9.1 Ensure new development is compatible with its natural surroundings and the built environment in terms of
architecture, scale, grading and massing.

Policy 9.6 Require the use and maintenance of extensive landscaping in new development and redevelopment projects to beautify the surroundings, screen outdoor uses, provide shade, establish pedestrian paths, buffer incompatible land uses and provide visual interest.

Policy 9.8. Develop and enforce development standards and design guidelines that provide clear yet flexible direction for achieving quality community design in new development and redevelopment projects throughout the community.

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-17
Resource Management Element
Resource Management Goal 3 Prevent incompatible development in areas that should be preserved for scenic, historic, conservation, mineral extraction, or public safety purposes.

Policy 3.1: Ensure incompatible development is avoided in those areas that are designated for scenic, historic,
conservation, mineral extraction, or public safety
purposes.

5.2.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on landform alteration and aesthetics if it:

1. Has a significant adverse effect on a scenic vista

2. Substantially damages scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway

3. Substantially degrades the existing visual character or quality of the site and its surroundings

4. Creates a new source of substantial light or glare that would adversely affect day or nighttime views in the area.

5.2.4 Impacts
The proposed Specific Plan contains several aesthetic features that have been assumed as part of the project and therefore shape the following impact analysis.

Applicable Visual Policies
An assessment of the project's relationship to visual resource policies in the General Plan is summarized below in Table 5.2-1, Consistency Determinations for General Plan Policies.

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-18
Table 5.2-1
Consistency Determinations for General Plan Policies
Policy Consistency Determination
General Plan Land Use Element
Land Use Goal 2: Manage and direct growth so that the community and its neighborhoods are protected and enhanced.

Policy 2.1: Assure that new development is complementary to the existing character of the City.

The Specific Plan sets forth the architectural and site design guidelines for the project, which ensures consistent high quality development that reflects the scale and development intensity of the community while allowing for flexibility in design. Therefore, the project is consistent with this policy.

Policy 2.7: Locate retail and commercial land uses along major circulation routes at major intersections where there is maximum access and visibility
The commercial portion of the project will be located adjacent to Sanderson Avenue, a major entry point into the City where it intersects with the future Bridge Street, which is one of the main project access points. Therefore, the project is consistent with this policy.

Land Use Goal 6: Preserve and protect the City's cultural, historic, agricultural, and visual resources.

Policy 6.7: Preserve and enhance public views of the
mountains and hillsides and other scenic vistas.

Mountain views are currently afforded across the site from public roadways in the project vicinity. Some lower mountain views may be temporarily obstructed by the project in some areas. Although there may be brief, interrupted views for passing motorists, there will be no permanent view blockage from surrounding areas.

Policy 6.10: Promote the maintenance of private and public properties to enhance the visual appearance of the
community.

The project will provide a significant enhancement to the community by utilizing a variety of compatible architectural styles, and specific standards and design guidelines for each Planning Area. It will also include extensive landscape treatments along adjacent highways and internal streets as well as the paseo walkways between land uses.

Land Use Goal 9: Encourage thoughtful community design that enhances San Jacinto's quality of life.

Policy 9.1: Ensure new development is compatible with its natural surroundings and the built environment in terms of architecture, scale, grading and massing.

The project Specific Plan establishes compatible design guidelines, including landscape design for roadways, parks, and other common use areas, and architectural guidelines for all residences, commercial and mixed-use development.

These guidelines will ensure that each of the project
components relate to one another as well as to surrounding land uses.

Policy 9.6: Require the use and maintenance of extensive landscaping in new development and redevelopment projects to beautify the surroundings, screen outdoor uses, provide shade, establish pedestrian paths, buffer incompatible land uses and provide visual interest.

The project Specific Plan establishes landscaping design guidelines that provide a variety of landscape treatments along adjacent highways and internal streets, which include planted medians, parkway trees, shrubs, and groundcovers. There will also be landscaped walkways, drainages, and parks, which separate the various land uses.

Policy 9.8: Develop and enforce development standards and design guidelines that provide clear yet flexible direction for achieving quality community design in new development and redevelopment projects throughout the community
The Specific Plan Design Guidelines for architecture and landscaping ensure consistent development standards
throughout the project and will therefore be consistent with this policy.

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-19
Would the project have a significant adverse effect on a scenic vista? The General Plan identifies hillside and mountain views as significant resources which should be protected and enhanced. Views to mountain backdrops/background are currently available across the site from existing roadways west, north, and south of the site. Due to the distance of the site from Ramona Expressway and Warren Road, future structural development of the Villages of San Jacinto would not physically obstruct the distant "background" views of the San Bernardino or San Jacinto mountain ranges from these roadways. The skyline and surrounding rural landscape is typical of what motorists experience as they travel along the adjacent roadways to the project site. However, development of the project may result in partial obstruction of existing lower mountain views for auto travelers along Sanderson Avenue, although this would be perceived only for a short distance, as views of the distant mountains would open up again once they have driven by the development. The project would not obstruct views of the surrounding mountains as seen from any nearby parks, trails, or other recreational uses, as these types of uses are not found in close proximity to the project site. Consequently, the proposed development, including the required 11-foot sound barrier along Sanderson Avenue (see Section

5.11.5, Mitigation Measures, Mitigation Measure 5.11-a), will not result in a significant visual impact to the existing views of the surrounding mountain backdrops. However, in order to soften the potential visual monotony of a continuous 11-foot wall along Sanderson Avenue, the wall will be constructed atop a landscaped berm of varying heights between 3 to 5 feet high, and would have extensive landscaping between the street and wall to help minimize any perceived visual impact of the wall. Therefore, the wall, combined with the berm will constitute an 11-foot sound barrier. According to the Specific Plan, this project frontage along Sanderson Avenue will include a 6-foot meandering sidewalk within a 16-foot landscaped parkway that features clusters of palm trees, pine trees, background shrubs and other shrub and ground cover plantings. The project site is not located within or adjacent to a State Scenic Highway (http://www.dot.ca.gov), and the project would not have a significant adverse visual impact on existing residences.

The project will include an extensive system of parks and paseos along with landscaping on major internal and adjacent roadways that will provide a consistent plant theme throughout the project. These elements along with the other open space enhancements as described above will result in a net visual improvement of the project site that provides a high quality aesthetically attractive development. Therefore, the project will not have a significant adverse impact on a scenic vista and no mitigation measures are required.

Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? State Highway 74, which is approximately four miles south of the project site, is listed as an eligible but not officially designated State Scenic Highway on the California Scenic Highway Mapping System (http://www.dot.ca.gov/hq/LandArch/scenic_highways/index.htm) in the

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-20
project vicinity. State Highway 74 is an Officially Designated State Scenic Highway approximately 5.5 miles southeast of the project site where it descends from the San Jacinto Mountains. However, due to the distance from this highway and intervening uses, the proposed project will not be visible. The proposed project does not currently support rock outcroppings or trees, and therefore would not involve disturbance of any trees, rock outcroppings or historic buildings, and would not damage a scenic resource.

Would the project substantially degrade the existing visual character or quality of the site and its surroundings?
Visual Quality of Site
The existing visual quality of the site varies from very low, for those portions with structures or other improvements, to moderate, for those areas employed for grass sod cultivation. However, the most prominent visual feature of the project site, where it is most visible along Sanderson Road, is vacant agricultural land consisting of weedy invasive species that have accumulated since the majority of agricultural production was discontinued. The cultivated agricultural portions are not highly visible from adjacent roadways. Therefore, the overall visual quality of the project site itself is considered low.

Implementation of the Villages of San Jacinto project would result in the development of the site with urban uses and structures including commercial, residential, and school buildings. The character of the site will be changed from one of mixed agriculture and fallow agriculture fields to one of a suburban/developed nature. However, the proposed project includes five parks totaling approximately 40 acres, including three public parks and two private neighborhood parks that provide a significant open space buffer among developed areas. Other open space amenities include an 11-acre lake and associated swim lagoon and beach area as well as a system of landscaped trails or "paseos" that serve as pedestrian linkages between land uses. There will also be extensive landscape treatments along adjacent highways and internal streets, which include planted medians, parkway trees, shrubs, and groundcovers, which will enhance the roadways and provide further visual contrast between proposed uses. Another feature that provides visual transition is a vegetated detention basin/drainage channel system along the western perimeter of the project site. The proposed system of open spaces would provide both on-site and off-site visual benefits to compensate for the loss of existing open space character of the site and surroundings, and would not conflict with the planned residential, commercial and open space uses in the adjacent community.

The project Specific Plan establishes compatible design guidelines including landscape design for roadways, parks and other common use areas and architectural guidelines for all residences, commercial and mixed-use development. These guidelines will ensure consistent development standards throughout the project that will not result in substantially degrading the existing visual

5.2 LANDFORM ALTERATION AND AESTHETICS
Villages of San Jacinto EIR 4307-01
August 2009 5.2-21
character or quality of the site and its surroundings. As discussed in Section 3.0, Project Description, the project will result in up to 1,329 low and medium density single-family residences, 22.7 acres of commercial uses, and 26.3 acres of mixed-use development. The residences will have a variety of architectural styles and will vary between one and two stories up to a maximum height of 35 feet. Architectural design guidelines will also be used to provide direction and inspiration for final design of the commercial and mixed use portions of the project. Building masses will be clustered to avoid long straight building facades and variation of building heights up to a maximum height of 35 feet will be required. Approval and implementation of the Specific Plan shall constitute compatibility with existing visual character, and no further mitigation measures are required.

Would the project create a new source of substantial light or glare that would adversely affect day or nighttime views in the area?
Light and Glare
The project would introduce additional night lighting within the project vicinity as well as potential new sources of glare (i.e., glass and reflective exterior surfaces). Particularly the commercial components of the site have the potential to produce significant night lighting impacts upon adjacent uses in the vicinity as well as proposed residential land uses within the project itself. Additionally, the project will require street lighting, trail lighting, and lighting associated with outdoor recreational activities. The Specific Plan requires that there are uniform lighting standards throughout the project and that lighting along trails shall be a minimum of 20- feet from rear or side yards to reduce light spill-over effects. All exterior lights are required to be shielded and focused to minimize spill light into the night sky or adjacent properties. Should Planning Area 14 be purchased by the San Jacinto Unified School District for development as a high school, any potential light or glare impacts would need to be addressed by the School District in the course of their environmental compliance for that project. However, a mitigation measure has been added (see Section 5.2.5, Mitigation Measures, Mitigation Measure 5.2-b) which requires notification of homeowners in the vicinity of the school site that there may be lighted ball fields in the future should the school district proceed with plans for the proposed high school. Metal or other reflective exterior surfaces and finishes within the commercial components of the site could create new sources of light or glare resulting in significant glare impacts for adjacent residential, park, and agricultural uses. In order to reduce this potential impact to a less than significant level, mitigation is provided (see Section 5.2.5, Mitigation Measures, Mitigation Measure 5.2-a).

5.2.5 Mitigation Measures

5.2-a To avoid light and glare impacts, future submittals for commercial portions of the project development shall be required to prepare a photometric lighting plan. The lighting plan shall demonstrate that project lighting is shielded from surrounding properties and that only the minimum amount of lighting required for safety purposes is provided to avoid adverse effects on surrounding areas. In general, lighting fixtures shall be shielded downward and away from the adjacent residential areas and public roadways.

Commercial development plans shall also be reviewed by the City to ensure the avoidance of substantial areas of reflective surfaces for building exteriors.

5.2-b A Notice-to-Property Owner shall be recorded on a separate buyer information sheet with the final map providing notice to potential future property owners in the vicinity of the school site (i.e., Planning Areas 1, 3, and 19) that there may be lighted ball fields in the future should the school district proceed with plans for the proposed high school.

5.2.6 Residual Impacts/Level of Significance after Mitigation With the application of the above mitigation measure, project impacts related to light and glare would be reduced to levels below significance. No significant impacts related to aesthetics, visual conditions, or landform modification have been identified.

5.3 AGRICULTURAL RESOURCES

5.3.1 Introduction and Methodology
This section describes existing agricultural uses of the project site and discusses potential project impacts to local, regional, and statewide agricultural resources.

The character of existing agricultural uses of the subject site and surrounding areas was determined based on a field survey and review of aerial photography. In addition, State of California (2006) Resources Agency on-line mapping information was reviewed to assist in characterizing the agricultural resources of the site. Finally, the agricultural characteristics of the site as they relate to agricultural viability and importance as a significant agricultural resource were defined and analyzed utilizing the California Agricultural Land Evaluation Site Assessment (LESA) model (State of California 1997), included as Appendix B. The LESA model evaluates soil resource quality of the site, project site size, water availability, surrounding agricultural lands, and surrounding protected resource lands. These characteristics are then rated, weighed, and combined, resulting in a single numeric score that is the basis for making a determination of the project site's agricultural value, and thereby to identify the significance of potential project impacts of converting the agricultural land resources to other land uses. The LESA model is identified in the CEQA Guidelines as an optional methodology for addressing impacts to farmland and agricultural resources. Additional information regarding the LESA model is provided in Section 5.3.4.

5.3.2 Existing Conditions
Existing Land Uses
The 475.1-acre project site is located in the northwest portion of the City of San Jacinto in an area consisting primarily of rural agricultural uses. The project site has been used as pasture land and/or a farming operation, similar to surrounding properties, for over 100 years. The subject site formerly occupied predominantly by active agricultural cultivation in the form of turf farming with various support facilities, including roads, irrigation systems, and minor appurtenant buildings used for storage of farm materials and equipment. However, only a small portion of the project site is currently being used for turf farming, with the remainder being vacant and containing mostly weedy invasive plants or natural vegetation. In addition, the southeast portion of the site, approximately 16 acres, has been recently utilized as a feedlot (supporting an average of 500 head of cattle). Water resources used to sustain the existing agricultural operations is provided primarily as recycled water by the Eastern Municipal Water District (EMWD), which is supplemented by groundwater produced by three on-site wells for which there are no restrictions on private use. Currently, irrigation for the turf farm operation consists of a combination of 95%

5.3 AGRICULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.3-2
reclaimed water and 5% groundwater. Water supply for the feedlot operation consists of groundwater produced by an on-site well.

Land uses north of the site continue to consist primarily of cultivated agricultural use in addition to duck ponds, the Colorado River Aqueduct, and the Ramona Expressway. Agricultural land uses occupy most areas directly west and east of the project site, including cultivated land and greenhouse operations, with the exception of rural residential development located just southeast of the project site and a residential neighborhood located northeast of the property where North Sanderson Avenue and the Ramona Expressway intersect. A municipal wastewater treatment plant owned and operated by EMWD is located directly south of the project site, and the San Jacinto Reservoir is located southeast of the property. The San Jacinto Valley has traditionally supported agriculture and rural residential land uses, but has recently been experiencing increased urbanization.

On-line mapping information posted by the State of California (2006) Resources Agency pursuant to the Farmland Mapping and Monitoring Program (accessed at www.conservation.ca.gov) indicates that the project site contains Prime Farmland, Unique Farmland, and Farmland of Statewide Importance and Local Importance defined as follows:
• Prime Farmland has the best combination of characteristics for producing crops. It produces sustained high yields when properly managed, and is not in or committed to urban development.
• Unique Farmland is other than prime farmland but capable of producing high-value crops. • Farmland of Statewide or Local Importance does not qualify as Prime or Unique Farmlands, but is irrigated land determined to be important by state and local governments.

5.3.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on agricultural resources if it:

1. Would convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use

2. Would conflict with existing zoning for agricultural use, or a Williamson Act contract

3. Would involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non-agricultural use.

5.3 AGRICULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.3-3

5.3.4 Impacts
Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? The proposed project is located on a site that has been designated by the California Resources Agency as Prime Farmland, Unique Farmland, and Farmland of Statewide Importance. This impact is considered significant and is further quantified by use of the State of California (1997) Department of Conservation LESA model (see below).

Agricultural land throughout western Riverside County is under increasing pressure of conversion to urban uses. The proposed project would result in conversion of the entire project site, approximately 475.1 acres of land consisting of designated important agricultural resources, to urban-related uses.

Although analysis of agricultural impacts through use of the California Agricultural LESA model (State of California 1997) is not specifically tied to a significance criterion, the recent conversion of agricultural uses to urban land uses throughout the western Riverside County area is an issue of concern for many stakeholders. Therefore, in an abundance of caution, the LESA model is used for rating the relative quality of land resources based upon site-specific measurable features, such as soil resource quality, project site size, water availability, surrounding agricultural lands, and surrounding protected resource lands. The LESA method was developed by the Department of Conservation (in 1995), intended to provide CEQA lead agencies with an optional methodology to ensure that significant effects on the environment of agricultural land conversions are quantitatively and consistently considered in the environmental review process (Public Resources Code Section 21095).

The LESA model is composed of six different factors. Two Land Evaluation factors are based on measures of soil resource quality. Four Site Assessment factors provide measures of project size, water resource availability, surrounding agricultural lands, and surrounding protected resource lands. For a given project, each of these factors is separately rated on a 100-point scale. The factors are then weighted relative to one another and combined, resulting in a single numeric score for a given project, with a maximum attainable score of 100 points. It is the total project score that becomes the basis for making a determination of a project's potential significance, based upon a range of established scoring thresholds.

The LESA model worksheets are found in Appendix B. Using the LESA model, the Land Evaluation portion of the model equals 22.53, and the Site Assessment portion equals 38.93, for a total project score of 61.46. According to the LESA manual, a score of 60 to 79 points is considered significant unless either the Land Evaluation or Site Assessment subscore is less than

5.3 AGRICULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.3-4
20 points. Because the Land Evaluation and the Site Assessment subscores (22.53 and 38.93, respectively) are both greater than 20, the overall score of 61.46 indicates that the agricultural lands of the project site are considered a significant resource and, therefore, conversion of the project site's agricultural lands would significantly impact the agricultural resources of the project site.

The proposed project would irreversibly convert land currently under agricultural production and identified as containing significant agricultural resources to urban uses and would contribute to incremental urbanization of a predominantly rural area sustaining existing agricultural land uses.

As such, the proposed project would potentially result in a significant, unmitigable, adverse impact to agricultural resources of both local and regional importance. As discussed below in Section 5.3.6, Residual Impacts/Level of Significance after Mitigation, there are no feasible mitigation measures to reduce this impact below a level of significance.

In addition, development of the proposed project would potentially result in significant urban/rural land use conflicts between the planned development and existing agricultural uses surrounding the project site. Conflicts would potentially include fertilizer and pesticide application drift into the proposed residential area, residential complaints about noise, odor and dust resulting from site preparation activities associated with adjacent agricultural uses, and increased trespassing onto agricultural lands. Implementation of Mitigation Measure 5.3-a, identified in Section 5.3.5, Mitigation Measures, would serve to alleviate land use conflicts associated with new residential development and existing agricultural land uses. Further, fencing and vegetation set-backs contained in the Specific Plan will help to reduce potential inconsistencies with surrounding agricultural land. However, potentially significant impacts to sustained agricultural resources would result from the proposed project development, as the identified land use conflicts associated with urbanization of agricultural lands may ultimately result in making agricultural operations more difficult to sustain, and thereby more susceptible to conversion over time, resulting in cumulative impacts to agricultural resources of the area.

Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract?
The proposed project would not conflict with existing zoning for agricultural use. No portion of the project site is currently zoned for agricultural use; therefore, no conflicts are anticipated to occur with respect to the proposed residential conversion of the property and existing zoning designations. In addition, the site is not covered by special agricultural status, such as a Williamson Act contract.

Therefore, no impacts related to agricultural zoning or a Williamson Act contract would occur.

Would the project involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non-agricultural use? The project itself may contribute to surrounding lands being more susceptible to conversion over time, resulting in cumulative impacts to agricultural resources of the area.

5.3.5 Mitigation Measures
Project-Specific Mitigation Measures

5.3-a A Notice-to-Property-Owner shall be recorded on a separate buyer information sheet with the final map providing notice to potential future property owners of the proposed development that the property is located in an area of active agricultural land uses that may potentially result in inconvenience and/or discomfort associated with adjacent agricultural operations including noise, odors and dust generation, and chemical drift.

5.3.6 Residual Impacts/Level of Significance after Mitigation The proposed project would result in the direct loss of agricultural land resources determined to be significant pursuant to the California Agricultural LESA model, and which are identified as important farmlands by the State of California (2006) Resources Agency Farmland Mapping and Monitoring Program. There are no identified mitigation measures that would substantially reduce the impacts associated with the permanent loss of the site's agricultural resources. The City’s General Plan EIR (January 2006) discusses a number of reasons mitigation for loss of agriculture is infeasible. Rising land costs to replace agricultural lands, rising water costs, labor costs, urbanization and environmental regulations all contribute to ongoing conversion of farmland.

Although the conclusion that agricultural preservation was infeasible for the above reasons was conducted several years ago, these factors are still prevalent and remain as constraining factors to agricultural conservation. Without property owner cooperation and substantial financial incentives, it is infeasible to provide permanent on or offsite mitigation to replace converted farmland. Mitigation measures for the proposed development have been identified to reduce the magnitude of significant impacts associated with potential land use conflicts resulting from development of the proposed residential development in an area supporting existing agricultural uses. However, a residual significant, unmitigable impact would remain due to the inherent incompatibility of agricultural and urban land uses, and due to the cumulative effects of pressure to convert adjacent agricultural lands associated with urban development encroachment into the predominantly rural project area.

Therefore, given the above considerations, potential project impacts to agricultural resources are considered significant and not fully mitigable. As such, pursuant to CEQA, approval of the proposed project is likely to result in significant unavoidable agricultural resource impacts and requires that the decision makers provide findings of overriding consideration of project benefits that make the significant effects acceptable.

5.4 BIOLOGICAL RESOURCES

5.4.1 Introduction and Methodology
This section describes existing biological resources on the project site and discusses potential project impacts to resources. This analysis is based on the August 2005 Dudek and Associates Biological Resources Technical Report prepared for the project. This report is included as Appendix C to this EIR. Methods used to conduct the biological resources field reconnaissance and impact analysis are contained therein.

5.4.2 Existing Conditions
Setting
Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) The Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) is a comprehensive, multi-jurisdictional habitat conservation plan (HCP) focusing on conservation of species and their associated habitats in Western Riverside County. This plan is one of several large, multi-jurisdictional habitat-planning efforts in Southern California with the overall goal of maintaining biological and ecological diversity within a rapidly urbanizing region. The MSHCP will allow Riverside County and its cities to better control local land-use decisions and maintain a strong economic climate in the region while addressing the requirements of the state and federal Endangered Species Acts.

The MSHCP serves as an HCP pursuant to Section 10(a)(1)(B) of the federal Endangered Species Act of 1973, as well as a Natural Communities Conservation Plan (NCCP) under the NCCP Act of 2001. The MSHCP allows the participating jurisdictions to authorize "Take" of plant and wildlife species identified within the plan area. The United States Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG) have authority to regulate the take of threatened, endangered, and rare species. Under the MSHCP, the wildlife agencies have granted "take authorization" for otherwise lawful actions—such as public and private development that may incidentally take or harm individual species or their habitat outside of the MSHCP conservation area—in exchange for the assembly and management of a coordinated MSHCP conservation area.

The MSHCP is a "criteria-based plan" and does not rely on a hardline preserve map. Instead, within the MSHCP Plan Area, the MSHCP reserve will be assembled over time from a smaller subset of the Plan Area referred to as the Criteria Area. The Criteria Area consists of Criteria Cells (Cells) or Cell Groupings, and flexible guidelines (Criteria) for the assembly of conservation within the Cells or Cell Groupings have been developed for each Cell/Cell

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.4-2
Grouping. Cells and Cell Groupings also may be included within larger units known as Cores, Linkages, or Habitat Blocks.

The Villages of San Jacinto project is located within the San Jacinto Valley Area Plan of the MSHCP. A GIS overlay of MSHCP San Jacinto Valley Area Criteria Cells with the Villages of San Jacinto project boundary shows that the project lies outside of the Criteria Area with the exception of a small overlap of the southwestern portion of the site with Cells 2775 and 2878.

This overlap is approximately 250 feet wide and extends approximately 3,240 feet along the western property boundary. This slight Cell overlap does not correspond to any observable change in site features such as biological resources or topography; the site is in active agriculture (turf grass farm) both within and outside the area of overlap. For this reason, it was agreed (personal communication, Ken Graff, Riverside Regional Conservation Authority) that the overlap is a map registration issue, and MSHCP Criteria for Cells 2775 and 2878 would not apply to the Villages of San Jacinto Project but rather to the adjacent parcels to the west (see Figure 5.4-1, Project Relationship to Western Riverside County MSHCP). A letter from Charles V. Landry, Executive Director of the Western Riverside County Regional Conservation Authority (RCA), dated November 17, 2008, provides written confirmation of the previous conversation with Mr. Graff. This letter and the letter from the City requesting the RCA’s written confirmation is provided in Appendix C. However, certain plan-wide requirements would apply to the project, including habitat assessments/survey requirements for narrow endemic plant species and burrowing owl. The project has also been analyzed for consistency with MSHCP Section 6.1.2, Riparian/Riverine Resources.

Topography
The study area ranges from flat in the central and southern regions of the project site to gently sloping in the northeastern region just east of the proposed Odell Avenue. The highest elevational area on site is the western boundary of the site [approximately 1,480 feet above mean sea level (amsl)]; the lowest elevational area is on the north-central boundary of the site [approximately 1,460 feet amsl].

Soils
The project site consists of several soil categories. All of the soils developed in alluvium from granitic parent materials. Dello, Chino, and Grangeville soils are present in alluvial areas or on floodplains; Traver soils are present on valley plains and in basins. With the exception of Grangeville soils, these soils are all in shallowly-sloping areas (0%–5% slopes); Grangeville soils are sloped from 0%–15%. Dello and Chino soils are slowly permeable, while Grangeville and Traver soils are moderately well-drained. Traver soils are from slightly to strongly saline, and, in addition to other soil types not mapped on the project study area, are often associated with narrow endemic plant species.

Vegetation Communities
Several native vegetation communities/land cover types as well as non-native/non-natural land covers are located on the project site. Wetland vegetation communities are also found on the project site. A total of nine vegetation communities were identified on the project site—six native and three non-native. The three non-native types include agriculture, ruderal land and disturbed/developed land. The native vegetation types include open water, freshwater marsh, southern willow woodland, disturbed herbaceous wetlands, cismontane alkali marsh, and intermittent unvegetated stream channel.

Wildlife Resources
Wildlife found in the project area includes species generally associated with the habitat types identified above. A complete list of observed and expected sensitive wildlife species is provided in Appendix C to this EIR.

Site Observations
Figure 5.4-2, Biological Resources Map, depicts resources observed and mapped on site during the January through August 2005 field visits to the site. It should be noted that the project site undergoes regular mechanical disturbance associated with the agricultural operations, therefore updated biological resource studies have not been prepared.

Vegetation Communities
The entire 475.1 acre site was surveyed for biological resources. This survey area includes developed lands associated with the existing agricultural operations on site in addition to remaining undeveloped/undisturbed portions of the site. Table 5.4-1, Existing Biological Resources, provides a summary of each type of vegetation community found on the project site.

A description of each vegetation community is included in Table 5.4-1.

Open Water
Open water (i.e., pond) is a type of aquatic area that typically lacks emergent vegetation but supports hydrophytic vegetation, such as mule fat scrub, southern willow scrub, and freshwater marsh around its margins. Ponds represent an important resource for a variety of migratory waterfowl and provide habitat for amphibians and numerous species of aquatic insects. Areas of open water, in concert with the surrounding riparian vegetation, may receive considerable use by species more typical of upland habitats during the drier times of the year.

Three areas of open water totaling 4.22 acres are present within the study area: two detention basins—one along the northern property boundary and one along the southwestern property boundary—and one shallow depression along the southeastern property boundary. At the time of the wetlands delineation, these areas were filled with water and supported a variety of waterfowl.

Since the areas of open water on site have no connection to navigable Waters of the U.S., they are under the jurisdiction of CDFG and RWQCB only.

None of these areas mapped as open water on site would be classified as MSHCP riparian/riverine since they were artificially created.

Freshwater Marsh
Freshwater marsh is a wetland habitat type that develops where the water table is at or just above the ground surface, such as around the margins of lakes, ponds, slow-moving streams, ditches, and seepages. It typically is dominated by tall, emergent monocots, such as cattail (Typha sp.) and bulrush (Scirpus sp.).

Freshwater marsh on site is located around the perimeters of the detention basins and along the intermittent stream channel along the southern boundary of the site. This vegetation community occupies 0.23 acre and is dominated by cattails and bulrushes. Freshwater marsh on site is under the jurisdiction of CDFG and RWQCB only.

None of the areas mapped as freshwater marsh on site would be classified as MSHCP riparian/riverine since there were artificially created. 1490

Southern Willow Woodland
Southern willow woodland is similar to the southern willow scrub plant community described by Holland (1986) as "dense, broadleafed, winter-deciduous riparian thickets dominated by several species of Salix [willows], with scattered emergent Populus fremontii [Freemont cottonwood] and Platanus racemosa [western sycamore]." The understory is usually arrested in growth owing to the dense canopy. The 0.07-acre area of the study site mapped as southern willow woodland consists of a small group of larger, more mature Goodding's black willows (Salix gooddingii) with an open understory. Soils within this vegetation type are hydric (Chroma 1), and evidence of hydrology exists as water stained leaves and drainage patterns. This habitat is fed by two 1- foot pipes that outlet onto the property along the southern boundary. However, since this wetlands habitat type is not connected to navigable Waters of the U.S., it is not under the jurisdiction of the ACOE. Southern willow woodland on site is under the jurisdiction of CDFG and RWQCB only.

None of the areas mapped as southern willow woodland on site would be classified as MSHCP riparian/riverine since there were artificially created.

Disturbed Herbaceous Wetlands
Herbaceous wetlands were mapped in association with the northern detention basin on site.

Herbaceous wetlands support a predominance of low, herbaceous, hydrophytic vegetation.

Within this 0.05-acre habitat type on site, yellow nutsedge (Cyperus esculentus), a hydrophytic species, dominates the cover. Drainage patterns are evident, and soils are considered hydric (Chroma 2 with mottles). This habitat type lacks a surface connection to navigable Waters of the U.S., however, and thus is under the jurisdiction of CDFG and RWQCB only.

Disturbed herbaceous wetlands were also mapped in an area dominated by the non-native perennial pepperweed (Lepidium latifolium). No indicators of hydrology are present, and soils are not hydric (Chroma 2 without mottles), so disturbed herbaceous wetlands on site are under the jurisdiction of CDFG only. A total of 0.16 acre of disturbed herbaceous wetlands are present on site.

None of the areas mapped as disturbed herbaceous wetlands on site would be classified as MSHCP riparian/riverine since there were artificially created.

Cismontane Alkali Marsh
According to Holland (1986), vegetation classified as cismontane alkali marsh occurs in areas of alkaline soils that are saturated or inundated during most of the year. Characteristic species often in cismontane alkali marsh include yerba mansa (Anemopsis californica), sedges, salt grass, rushes, alkali heath (Frankenia salina), cattails, salt marsh fleabane (Pluchea purpurascens), and

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.4-10
cattails. Species dominating the 0.01-acre patch of cismontane alkali marsh along the southern property boundary include salt grass, alkali-mallow (Malvella leprosa), and salt heliotrope (Heliotropium curassavicum).

None of the areas mapped as cismontane alkali marsh on site would be classified as MSHCP riparian/riverine since there were artificially created.

Unvegetated Intermittent Stream Channel
Unvegetated channel refers to the intermittent drainage connecting several small patches of wetlands vegetation south of the detention basin along the southern boundary of the site.

Intermittent waters generally have a surface flow that, although not perennial, may be present for relatively long periods (greater than 24 hours) following rainfall events. Intermittent waters on site vary from two to three feet in diameter and occupy 0.01 acre of the project site. These channels are under the jurisdiction of CDFG and RWQCB.

None of the areas mapped as intermittent stream channel on site would be classified as MSHCP riparian/riverine since there were artificially created.

Agriculture
Agricultural lands, occupying 307.08 acres, compose the majority of the site. Most of the areas mapped as agriculture consist of an active turf-grass farming operation. A cattle feed lot, in the southeastern portion of the site, was also mapped as agriculture.

Ruderal
Ruderal habitat was mapped in areas not in active turf-farming operations which have been allowed to recolonize with weedy, non-native vegetation. Ruderal areas on site occupy 126.87 acres and are dominated by weedy species such as henbit (Lamium amplexicaule), knotweed (Polygonum arenastrum), red-maids (Calindrinia ciliata), rescue grass (Bromus catharticus), shepherd's purse (Capsella bursa-pastoris), (Sisymbrium irio), sow thistles (Sonchus spp.), shortpodded mustard (Hirschfeldia incana), cheeseweed (Malva parviflora), and common purslane (Portulaca oleracea).

Disturbed/Developed
Areas mapped as disturbed or developed refer to areas lacking vegetation, such as dirt roads, graded areas, structures, and buildings. A total of 36.42 acres of disturbed/developed area is present within the study area.

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.4-11
Wildlife Diversity
A total of 79 species of both non-sensitive and special-status wildlife was observed or detected on site. The complete list of wildlife species identified is provided as Appendix B of the Biological Resources Technical Report, included as Appendix C to this EIR.

Birds
Sixty bird species were observed during the survey visits (Appendix B). The diversity of birds is limited due to the high levels of agriculture and relatively low habitat quality, or lack of native habitats throughout the study area. The habitats and land covers within the study area provide foraging habitat for a variety of special-status bird species such as the burrowing owl (Speotyto [Athene] cunicularia hypugaea) (which is a MSHCP survey species), white-tailed kite (Elanus caeruleus), red-tailed hawk (Buteo jamaicensis), red-shouldered hawk (Buteo lineatus), northern harrier, (Circus cyaneus), American kestrel (Falco sparverius) and horned lark (Eremophila alpestris). The ponds on site provide habitat for waterfowl including western grebe (Aechmorphus occidentalis), white-faced ibis (Plegadis chihi), northern shoveler (Anas clypeata), mallard (Anas platyrhynchos), lesser scaup (Aythya affinis), bufflehead (Bucephala albeola), ruddy duck (Oxyura jamaicensis), American coot (Fulica americana), common moorhen (Gallinula chloropus), least sandpiper (Calidris minutilla), and common snipe (Gallinago gallinago). A full list of species detected is presented in Appendix B to the Biological Resources Technical Report.

Reptiles and Amphibians
Two reptile species were observed on site: side-blotched lizard (Uta stansburiana) and western fence lizard (Sceloporus occidentalis). These species are not considered special-status. No amphibian species were observed during the survey; however, one or more of the following nonsensitive species may occur within the study area: garden slender salamander (Batrachoseps attenuatus), western toad (Bufo boreas) and Pacific treefrog (Hyla regilla). Habitat quality for reptiles and amphibians is low, and the diversity of these species is expected to be low because of the small amount of habitat available and the likely negative effects of the active agriculture on site.

Mammals
Nine mammal species, or their sign, were observed within the study area during the survey including: black-tailed jackrabbit (Lepus californicus), brush rabbit (Sylvilagus bachmani), desert cottontail (Sylvilagus audubonii), Botta's pocket gopher (Thomomys bottae), California ground squirrel (Spermophilus beecheyi), coyote (Canis latrans), striped skunk (Mephitis mephitis), bobcat (Lynx rufus), and domestic cattle (Bos bovis). Brush rabbit and black-tailed jackrabbit are considered special-status.

Invertebrates
Seven non-sensitive species of butterfly and one fairy shrimp species were recorded during surveys including: Sara orange-tip (Anthocharis sara sara), cabbage butterfly (Pieris rapae), common white (Pontia protodice), pygmy blue (Brephidium exile), West Coast lady (Vanessa annabella), red admiral (Vanessa atalanta rubria), painted lady (Vanessa cardui), and versatile fairy shrimp (Branchinecta lindahli).

Sensitive Biological Resources
Sensitive Habitats
Sensitive habitats are those that are considered rare within the region, support sensitive plant and/or wildlife species, function as corridors for wildlife movement, or are regulated by local, state or federal agencies. Habitat types found on site that are considered sensitive include open water, freshwater marsh, southern willow woodland, disturbed herbaceous wetland, cismontane alkali marsh and intermittent unvegetated stream channel.

MSHCP Riparian/Riverine Areas, Vernal Pools and Fairy Shrimp Habitat No MSHCP riparian/riverine areas or vernal pools were located on site. However, some water resources on site were initially determined potentially suitable for threatened or endangered species of fairy shrimp; therefore, focused vernal pool branchiopod (i.e., fairy shrimp) surveys were conducted. No sensitive species of fairy shrimp were found on site (see Table 5.4-2, Jurisdictional Waters (Including Wetlands) Present on the Villages of San Jacinto Project Site).

Jurisdictional Waters
Since none of the wetlands or non-wetlands waters on site show a surface connection with "navigable Waters of the U.S.," none of these areas are under the jurisdiction of the U.S. Army Corps of Engineers (ACOE). All of these areas are under the jurisdiction of both RWQCB and CDFG, or, in the case of some areas of disturbed herbaceous wetlands, CDFG only (see Table

5.4-2, Jurisdictional Waters (Including Wetlands) Present on the Villages of San Jacinto Project Site). A total of 4.22 acres of open water, 0.23 acre of freshwater marsh, 0.07 acre of southern willow woodland, 0.05 acre of herbaceous wetlands (including 0.02 acre of disturbed herbaceous wetlands), 0.01 acre of cismontane alkali marsh, and 0.01 acre of intermittent unvegetated stream channel, all under the jurisdiction of RWQCB and CDFG, are present on site. An additional 0.16 acre of disturbed herbaceous wetlands under the jurisdiction of CDFG only is also present on site (See Table 5.4-2 and Figures 5.4-2, 5.4-3, and 5.4-4). Data station forms for the wetlands delineation can be found in Appendix F of the Biological Resources Technical Report (included in Appendix C to this EIR).

Sensitive Plants (MSHCP Narrow Endemic Plant Species)
Because the MSHCP includes coverage for certain plant species for which limited information was available at the time of creation of the MSHCP plan (generally plants of limited distribution considered narrow endemic plants), these plants were conditionally covered by the MSHCP. For these species, surveys are required within suitable habitat. The Villages of San Jacinto project is located within MSHCP Narrow Endemic Plant Species Survey Area (NEPSA) 3. Species of concern in NEPSA 3 are Munz's onion, San Diego ambrosia, many-stemmed dudleya, spreading navarretia, California Orcutt grass and Wright's trichocoronis. Focused surveys were conducted for these species. Because suitable habitat was present for the San Jacinto Valley crownscale, Parish's brittlescale, Davidson's saltscale, smooth tarplant, Coulter's goldfields, thread-leaved brodiaea, little mousetail and mud nama, focused surveys were also conducted for these species.

Prior to the survey, a search was also conducted using the CNDDB (2004) to thoroughly assess the sensitive floral resources that may occur on site. Table 4 in the Biological Resources Technical Report (included as Appendix C to this EIR) lists potentially occurring sensitive species according to the detailed search of the CNDDB and Dudek's knowledge of biological resources of this area. Table 3 in the Biological Resources Technical Report (included as Appendix C) includes a list of all sensitive plant species, their sensitivity status, habitat associations and likelihood for presence on site. No sensitive plant species in the NEPSA 3 survey suite were located on site. Approximately 170 smooth tarplant individuals were observed on site as were approximately seven Coulter's goldfields individuals.

Sensitive Wildlife
Table 4 in the Biological Resources Technical Report (included in Appendix C) includes a list of all sensitive wildlife species, their sensitivity status, habitat associations and likelihood for presence on site. A summary of this table follows:

Reptiles and Amphibians
No sensitive reptiles or amphibians were observed on site, and no state- or federally-listed reptiles or amphibians are expected to occur. Table 5 in the Biological Resources Technical Report (included as Appendix C) includes all sensitive reptiles and amphibians that have the potential to occur within the project study area. Sensitive reptile and amphibian species classified as California Special Concern (CSC) Species and having at least a moderate potential to occur on site include the western newt and the western spadefoot toad.

Birds
Focused surveys for the western burrowing owl were conducted per MSHCP requirements for the project site, which is located within the Burrowing Owl Survey Area. One pair of burrowing owls and several burrows were observed during the surveys (Figure 5.4-2, see also Appendix E, Burrowing Owl Focused Survey Report, to the Biological Resources Technical Report, included as Appendix C to this EIR, for more information). The pair is assumed to be nesting on site. Two individuals of Swainson's hawk (Buteo swainsoni), a state-listed threatened species, were observed perched on trees within the site (Figure 5.4-2). Ferruginous hawk, northern harrier, and horned lark were observed foraging within the study area; the loggerhead shrike, a federal species of concern and CSC species, was observed nesting and foraging on site (Figure 5.4-2).

White-tailed kite and turkey vulture were observed foraging on site (Figure 5.4-2). White-faced ibis was observed flying over the site during one survey visit. All of these species are covered species in the MSHCP.

In addition to these sensitive species observed, the great blue heron, prairie falcon, peregrine falcon, merlin and mountain plover could all utilize habitat on site during winter months. All of these species are covered species in the MSHCP. Western bluebird (sometimes considered sensitive by local environmental groups) also has a potential to forage on site during the winter months. Western bluebird is not a MSHCP covered species.

Mammals
Three sensitive mammal species or their sign were observed on site: black-tailed jackrabbit, bobcat and coyote, all are covered species in the MSHCP. Three additional species were assumed to utilize habitat on site, although were not observed: long-tailed weasel, gray fox and brush rabbit. Brush rabbit is a covered species in the MSHCP while long-tailed weasel and gray fox are not.

Invertebrates
No sensitive invertebrate species were observed on site during general wildlife surveys or are expected to occur within the project study area due to lack of suitable habitat (see Table 5 in Biological Resources Report). The vernal pool branchiopod survey that was conducted during the 2004-2005 wet season was negative for sensitive branchiopod species (see Appendix D of the Biological Resources Technical Report [included as Appendix C to this EIR] for vernal pool branchiopod survey report).

Fish
No sensitive fish species were observed on site during general wildlife surveys or are expected to occur within the project study area due to lack of suitable habitat (see Table 5 in Biological Resources Technical Report, included as Appendix C to this EIR).

Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the immigration and emigration of animals. Habitat linkages may function as wildlife corridors for some species and permanent habitat for others. Wildlife corridors and habitat linkages contribute to population viability in several ways: (1) they assure the continual exchange of genes between populations which helps maintain genetic diversity; (2) they provide access to adjacent habitat areas representing additional territory for foraging and mating; (3) they allow for a greater carrying capacity of species populations; and (4) they provide routes for colonization of habitat lands following local population extinctions or habitat recovery from ecological catastrophes (e.g., fires).

As illustrated in Figure 3-3, Site Location Map, the project study area is surrounded by agricultural lands to the north, east, and southwest; a water reclamation facility lies to the southeast of the site. Therefore, the project study area is not of high importance as a regional wildlife corridor or habitat linkage, i.e., it does not connect larger habitat areas or provide for regional wildlife movement. Furthermore, the site is not included a MSHCP Linkage or Constrained Linkage which has been identified constructed to maintain regional habitat linkages.

5.4.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on biological resources if it would:

1. Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive or special status species in local or regional plans, policies or regulations or by the California Department of Fish and Game or U.S.

Fish and Wildlife Service?

2. Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Services?

3. Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filing, hydrological interruption or other means?

4. Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?

5. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?

6. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional, or state habitat conservation plan?

5.4.4 Biological Resource Impacts
Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive or special status species in local or regional plans, policies or regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?
No sensitive reptiles or amphibians were observed on site, and no state- or federally-listed reptiles or amphibians are expected to occur. Three sensitive mammal species or their sign were observed on site: black-tailed jackrabbit, bobcat and coyote, all are covered species in the MSHCP (see full discussion of consistency with the MSHCP below). No sensitive invertebrate species were observed on site during general wildlife surveys or are expected to occur within the project study area due to lack of suitable habitat. No sensitive fish species were observed on site during general wildlife surveys or are expected to occur within the project study area due to lack of suitable habitat.

Focused surveys for the western burrowing owl were conducted per MSHCP requirements for the project site. One pair of burrowing owls and several burrows were observed during the surveys. In order to avoid potential indirect impacts related to burrowing owls, mitigation is provided (see Section 5.4.5, Mitigation Measures, Mitigation Measure 5.4-b).

Two individuals of Swainson's hawk (Buteo swainsoni), a state-listed threatened species, were observed perched on trees within the site (Figure 5.4-2). Ferruginous hawk, northern harrier, and horned lark were observed foraging within the study area; the loggerhead shrike, a federal species of concern and CSC species, was observed nesting and foraging on site (Figure 5.4-2).

White-tailed kite and turkey vulture were observed foraging on site (Figure 5.4-2). White-faced ibis was observed flying over the site during one survey visit. Because impacts to other sensitive wildlife species are covered under the MSHCP, no additional mitigation is proposed for impacts to these species. The project will therefore, not have substantial adverse impacts on any sensitive specieThe project would impact 100% of all onsite habitats, many of which are suitable habitat for special-status species regulated by local plans/policies (i.e., MSHCP) or the US Fish and Wildlife Service or California Department of Fish and Game.

Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? Please see discussion below regarding the project’s relationship with the MSHCP. Please see discussion above regarding the project’s potential impacts to wetland or riparian habitats which may be protected under local or regional plans, policies regulations or by the California Department of Fish and Game or US Fish and Wildlife Service.

Would the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filing, hydrological interruption or other means? Direct impacts associated with the development of the proposed project were calculated and are shown in Table 5.4-4, Impacts to Jurisdictional Waters (Including Wetlands) Present on the Villages of San Jacinto Project Site). As is shown in the table, all biological resources within the project boundaries were considered 100% lost. This includes 4.22 acres of open water, 0.23 acre of freshwater marsh, 0.07 acre of southern willow woodland, 0.03 acre of herbaceous wetlands (including 0.18 acre of disturbed herbaceous wetlands) and 0.01 acre of intermittent unvegetated stream channel (see Table 5.4-4).

Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? As discussed above, under Existing Conditions, the project study area is surrounded by agricultural lands to the north, east, and southwest; a water reclamation facility lies to the southeast of the site. Therefore, the project study area is not of high importance as a regional wildlife corridor or habitat linkage, i.e., it does not connect larger habitat areas or provide for regional wildlife movement. Furthermore, the site is not included a MSHCP Linkage or Constrained Linkage which has been identified constructed to maintain regional habitat linkages.

Therefore, the project will not have a significant impact on established migratory wildlife corridors.

Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? The project site is located within the MSHCP Planning Area. Consistency with this plan is discussed below. There are no other local policies ordinances protecting biological resources that would affect the proposed project.

Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional, or state habitat conservation plan?
As indicated in Section 5.4.2, Existing Conditions, the project has been determined not to be subject to reserve assembly criteria under the MSHCP due to the determination that cell designations located on the project site are the result of a mapping/registration error. Therefore, from a reserve assembly perspective (or absence of criteria area), the project is consistent with the MSHCP. That said, the project was also subject to additional MSHCP requirements, namely narrow endemic plant surveys, burrowing owl surveys, fairy shrimp surveys and riparian/riverine resources guidelines.

On-site water resources were also analyzed for consistency with riparian/riverine resources.

While the project supports numerous wetland and water habitat, the man-made nature of these resources (largely for use in agricultural operations) eliminate them from being characterized as riparian/riverine per the MSHCP (see below for further discussion of MSHCP consistency).

Therefore, the proposed project would be consistent with the MSHCP in terms of preservation of riparian/riverine resources. Suitable habitat on the project site was surveyed for sensitive fairy shrimp species. While common fairy shrimp species were observed in on-site habitat, sensitive fairy shrimp species were not observed. Therefore, the project would be consistent with MSHCP fairy shrimp survey and conservation directives. Suitable habitat was surveyed for all NEPSA 3 plant species. These species were not observed on site, therefore the project would not conflict

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01

with MSHCP narrow endemic survey and conservation requirements. Two sensitive plant species, Coulter's goldfields (seven individuals) and smooth tarplant (approximately 170 individuals), were observed within the proposed impact area. Coulter's goldfields and smooth tarplant are covered species under the MSHCP but are not considered narrow endemic species by the MSHCP plan. These plants would be directly impacted by the proposed project. Impacts to these species would not be considered significant; the loss of 170 individuals of smooth tarplant and seven individuals of Coulter's goldfields are relatively small impacts to these species, which are fairly well distributed throughout the MSHCP plan area. In addition, these species are not MSHCP narrow endemic plants, and impacts to these species on the Villages of San Jacinto Project Site do not require any project-specific conservation measures such as salvaging for transplantation on another site. Because these species are covered under the plan, avoidance or impact minimization measures such as transplantation or seed salvaging is not necessary.

One pair of burrowing owls was observed on site. The project's impacts to these species are covered in accordance with the Species Conservation Objectives for the burrowing owl listed in the MSHCP. The project site does not support long-term conservation value for burrowing owl because of limited occupation of the species on the site. That said, in order to comply with the specific Burrowing Owl Survey Area provisions of the MSHCP, passive relocation to avoid direct impacts to known individuals will be required. In order to comply with MSHCP Burrowing Owl requirements, mitigation is provided. (see Section 5.4.5, Mitigation Measures, Mitigation Measure 5.4-b).

Adjacent MSHCP Lands
The Villages of San Jacinto Project is directly east of Criteria Cells 2775 and 2878. Although no development or establishment of MSHCP conservation areas has occurred as of yet in these criteria cells, some level of conservation may occur in the easternmost portions of the cells, directly adjacent to the Villages of San Jacinto Project site. Depending on proximity of these MSHCP conservation lands to the Villages of San Jacinto Project site, some level of edge effects on the conservation area may occur. Section 6.1.4 of the MSHCP, Guidelines Pertaining to the Urban/Wildlands Interface, addresses the indirect effects associated with locating development in proximity to the MSHCP conservation area and discusses measures to minimize these indirect effects. Several types of potential indirect effects on adjacent MSHCP conservation areas are discussed: drainage, toxics, lighting, noise, and exotic species.

Drainage
MSHCP requires that proposed developments in proximity to the MSHCP conservation area shall incorporate measures required through the NPDES requirements, to ensure that the quantity and quality of runoff discharged to the MSHCP conservation area is not altered in an adverse way. In particular, measures shall be put in place to avoid discharge of untreated surface runoff from developed and paved areas into the MSHCP conservation area. Stormwater systems shall

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.4-25
be designed to prevent the release of toxins, chemicals, petroleum products, exotic plant materials or other elements that might degrade or harm biological resources or ecosystem processes within the MSHCP conservation area.

The Villages of San Jacinto Project contains an extensive system of drainage basins, greenbelts, and detention basins/lakes engineered to provide for treatment of surface runoff prior to leaving the site. In addition, a SWPPP addressing construction-related and post-construction related erosion and runoff issues will be prepared and implemented (see Section 5.8, Water Quality and Hydrology). Therefore, indirect impacts on potential adjacent MSHCP conservation area lands due to drainage of harmful elements are not anticipated.

Toxics
Land uses proposed in proximity to the MSHCP conservation area that use chemical bioproducts such as manure that are potentially toxic or may adversely affect wildlife species, habitat, or water quality are required to incorporate measures to ensure that application of such chemicals does not result in discharge to the MSHCP conservation area. Although chemical bioproducts such as manure are not anticipated to be used on the Villages of San Jacinto Project site, project design measures and implementation of the SWPPP as discussed above would also prevent discharge of potential toxics into any adjacent MSHCP conservation areas. Therefore, indirect impacts on potential adjacent MSHCP conservation area lands due to toxic materials on the Villages of San Jacinto Project site are not anticipated.

Lighting
Due to the land uses proposed by the project, an increase in night lighting is anticipated. In order to avoid potential indirect impacts related to night lighting, mitigation is provided (see Section

5.4.5, Mitigation Measures, Mitigation Measure 5.4-c).

Noise
The MSHCP requires that "proposed noise-generating land uses affecting the MSHCP conservation area shall incorporate setbacks, berms or walls to minimize the effects of noise on MSHCP Conservation Area resources.” For planning purposes, wildlife within the MSHCP Conservation Area should not be subject to noise that would exceed residential noise standards.

Since the proposed land uses on a portion of the project site would be located adjacent to offsite MSHCP criteria cells include residential, school, park, and commercial/mixed use, noise is not expected to exceed residential noise standards (see Section 5.11, Noise). Therefore, impacts on potential adjacent MSHCP conservation lands due to increased noise are not anticipated.

5.4 BIOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.4-26
Invasives
Due to the project's location adjacent to land that could potentially be conserved through the MSHCP Plan, potential indirect impacts related to invasive species may occur. In order to avoid potential impacts, mitigation is provided (see Section 5.4.5, Mitigation Measures, Mitigation Measure 5.4-d).

Indirect impacts to adjacent vegetation communities primarily would result from adverse "edge effects" as cited above. For the proposed project, the potential indirect impacts resulting from construction activities include dust, noise, and general human presence that may temporarily (or in the case of general human presence, permanently) disrupt species and habitat vitality and lead to construction-related soil erosion and runoff. However, all project grading will be subject to the typical restrictions (e.g., Best Management Practices) and requirements that address erosion and runoff, including the federal Clean Water Act, NPDES, and preparation of a SWPPP. In addition, as the site is surrounded by agriculture and an EMWD water reclamation facility, impacts to sensitive vegetation types adjacent to the project site are highly unlikely. See Section 5.8, Water Quality and Hydrology.

Non-MSHCP Covered Species
The June 17, 2003, Final MSHCP EIR/EIS analyzed other, non-covered species considered to be sensitive in the western Riverside County area. This EIR determined that other species which were not covered under the plan, would not be significantly affected by adoption of the plan.

Therefore, any non-covered species in the MSHCP would not be considered significant.

5.4.5 Mitigation Measures
Project Specific Mitigation Measures

5.4-a Mitigation for impacts to jurisdictional wetlands and non-wetlands waters as required by RWQCB and CDFG, will consist of: (1) off-site creation, (2) a combination of off-site creation and enhancement of wetlands of equal or higher habitat quality, or (3) purchase of wetlands mitigation credits in an approved mitigation bank. Because wetlands/waters on the Villages of San Jacinto project site are isolated, of low overall quality (contain large quantities of non-native species), and are surrounded by agricultural lands, they do not provide high quality habitat for riparian-dependant wildlife species, therefore mitigation onsite would not result in equal or greater wetland habitat value. Mitigation for on-site wetlands/waters impacts would be a biologically equivalent or superior alternative to avoidance of these impacts. The above not withstanding, wetlands areas created, enhanced, or preserved through the project's wetlands mitigation plan would be connected to other wetlands/riparian/riverine areas and would provide overall biological value to the peregrine falcon and other sensitive wildlife and plant species. Wetland

mitigation ratios are based on past experience developing appropriate mitigation for impacts to similar wetland and/or Waters of the US.

Cismontane Alkali Marsh
Mitigation for impacts to 0.01 acre of cismontane alkali marsh would be accomplished through the creation, or a combination of creation and enhancement, of wetlands of equal or higher habitat quality at a 3:1 ratio (i.e., 0.03 acre). Mitigation can also be accomplished through the purchase of wetlands mitigation credits in an approved mitigation bank.

Southern Willow Woodland
Mitigation for impacts to 0.07 acre of southern willow woodland would be required at a ratio of 4:1 (i.e., 0.28 acre) (see Section 5.4 in the EIR). Mitigation can be accomplished through the creation, or a combination of creation and enhancement of wetlands of equal or higher habitat quality. Mitigation can also be accomplished through the purchase of wetland mitigation credits in an approved mitigation bank.

Pre-construction presence/absence surveys for burrowing owl within the survey area where suitable habitat is present will be conducted for all Covered Activities through the life of the permit.

Surveys will be conducted within 30 days prior to disturbance.

Take of active nests will be avoided. Passive relocation (use of one way doors and collapse of burrows) will occur when owls are present outside the nesting season.

Because impacts to other sensitive wildlife species are covered under the MSHCP, no additional mitigation is proposed for impacts to these species. However, if construction activity is to take place during the breeding season (i.e., January through October), a onetime biological survey for nesting bird species would be conducted within the proposed impact area no earlier than 72 hours prior to construction. This survey is necessary to assure avoidance of impacts to nesting native birds (per the federal Migratory Bird Treaty Act). If nesting birds are detected within vegetation which is to be impacted, the nest location(s) will be protected. A buffer of 25 to 300 feet (specific width to be determined by the project biologist according to species of bird) around the nest will be avoided until fledging.

Sample language for inclusion in sale documents would be submitted to the Planning Department for approval prior to approval of a certificate of occupancy. Therefore no indirect effects due to invasive species are anticipated.

5.4.6 Residual Impacts/Level of Significance after Mitigation The proposed project is consistent with the Western Riverside County MSHCP which, aside from Clean Water Act requirements, fully mitigates for impacts to biological resources within western Riverside County. Implementation of suggested mitigation measures will ensure that project impacts are mitigated to a level below significance.

5.5 CULTURAL RESOURCES

5.5.1 Introduction/Methodology
The following discussion focuses on the project's relationship to existing cultural resources, potential impacts to these resources and mitigation measures required to reduce these impacts to a level below significance. A residual impact statement has been included in order to characterize the level of significance of impacts after mitigation measures have been applied.

Preparation of this section involved summarizing information contained in the December 2004 Cultural Resources Study for the project site, prepared by ASM Affiliates. This section summarizes existing condition information, and uses the City of San Jacinto CEQA Significance Thresholds, specifically the cultural resource thresholds, to determine if cultural resource impacts were considered significant under CEQA. Mitigation measures were developed by cultural resource consultants, ASM Affiliates.

For reference purposes, the March 2005 Cultural Resources Study for the project is included as Appendix D to this EIR. Methods used in the preparation of this December 2004 report are contained therein.

5.5.2 Existing Conditions
Cultural History
The project area is located in a region intermediate between the desert regions to the east and the coastal region to the west. As such, it is likely to have been affected by population movements from both the coastal and desert regions. There is a significant body of research that was developed during the Eastside Reservoir Project (now referred to as Diamond Valley Lake) planning and environmental study which has helped to provide a cultural resource chronology baseline for the western slopes of the Santa Rosa and San Jacinto Mountains. These sources can be applied for the purposes of a general cultural history, especially for the Late Prehistoric period, assuming that Native American mobility and resource use practices extended across the environmental zones from the deserts to the mountains, as evident from ethnohistoric sources.

These sources can not provide clarification on patterns of social organization, settlement, territoriality and seasonality as they relate to the deep past. It is likely that these patterns changed over time with changing environmental conditions, resident tribal affiliation and demographics.

The prehistoric chronology is divided into three periods, each characterized by differing patterns of socio-political organization, technology, resource focus and land use. They include the Paleoindian, Archaic and Late Prehistoric periods.

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-2
Paleoindian Period
The Paleoindian period is represented by several archaeological complexes, including what are referred to as the related Fluted-Point and Western Pluvial Lakes traditions in the Mojave Desert, and the Paleo-Coastal tradition on the Pacific coastal plane. Among the best known archaeological complexes of tool types and settlement distributions in the desert is the Lake Mojave complex. On the coastal plane and Imperial Valley is the San Dieguito complex.

Small, highly mobile bands of hunters and gatherers depended on various game animals and an extensive rather than intensive pattern of plant exploitation. Sites tend to occur along former pluvial lakes and desert pavements, or along major stream channels. Milling tools are absent in the desert and rare on the coast, suggesting minimal use of hard seeds. The stone tool kit included foliate points or knives, long-stemmed points, lanceolate bifaces, discoidals, burins, crescents, flake and core scrapers, choppers, hammerstones, cores, drills, gravers and casual flake tools.

Archiac Period (8000–1500 B.P.)
Over the long duration of the Archaic period, there was a gradual shift from small, highly mobile hunters and gatherers practicing a forager pattern to larger groups with a diversity of settlement types involving residential bases, temporary camps, strategically located cache sites and specialized resource collecting localities. This pattern reflects increasing intensification and a shift from foragers to collectors who practiced logistical patterns of mobility to accommodate seasonally available resources. Coincident with these changes were the diversification of food resources and new specialized technologies with which to exploit them. Projectile points reflect the shift to the use of atlatl and dart. Milling tools become ubiquitous and reflect increased exploitation of seeds and nuts. Larger residential base sites tend to occur at reliable water sources such as springs or tanks, with temporary camps near seasonal stream channels, extinct rivers, playas, high terraces above sinks and rockshelters.

Some later Archaic sites are known, however, from the Colorado Desert that indicate occupations along the boundary between the low desert and Peninsular Ranges and at more favored habitats at springs and tanks. The most substantial Colorado Desert site is Indian Hill Rockshelter in Anza-Borrego Desert State Park where 1.5 m of Archaic period deposits were excavated below a Late Prehistoric component. Most significant were 11 rock-lined cache pits and numerous hearths indicative of either a residential base or a temporary camp in which food and tool storage was integral to the hunting and gathering settlement-subsistence strategy. Also recovered were numerous Elk-eared dart points, flaked and milling stone tools and three inhumations, one of which was radiocarbon dated to 4070 "100 B.P." Two similar rock-lined pits were excavated at a small rockshelter in Tahquitz Canyon near Palm Springs. The small quantity

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-3
of artifacts at that site suggested strategically stored food and seed processing equipment of small mobile groups.

Late Historic Period (1500–100 B.P.)
The major archaeologically visible technological and cultural innovations of this period are the introduction of pottery making by the paddle-and-anvil technique, bow-and-arrow technology around 1200 B.P., a shift from inhumation to cremation burial and the introduction of floodplain agriculture on the Colorado River about the same time, although exact dating of early domesticates is lacking. This was also the period when obsidian trade relations shifted from the Coso sources in the Mohave Desert to the Obsidian Butte source in the Salton Trough, when Lake Cahuilla did not submerge it. Ceramics and cultigens were introduced from either Mexico or through the Hohokam culture of the Gila River.

The ancestral Cahuilla were certainly exposed to domesticates at an early time, although opinions differ on when they adopted horticulture as a substantial part of their economy. It may have been a secondary pursuit for the production of specialty foods and fibers or gourds in the prehistoric period, although that has not been established archaeologically, as yet. Agricultural intensification and ditch irrigation techniques may not have occurred until after exposure to the mission system in historic times.

Bow-and-arrow technology, seed-beaters and other sophisticated hunting and gathering technology may also be related to the spread of Numic and Takic peoples from the southern Great Basin. Late Holocene flooding of Lake Cahuilla may have accelerated contacts between people of the ancestral Yumans of the Colorado River and the ancestors of the Cahuilla in the Coachella Valley and Peninsular Ranges. Such contacts through ceremonial and economic exchange may have resulted in a cultural dynamic that formed the Patayan Pattern and the resulting cultures of the ethnohistoric period. Long-range travel to special resource collecting zones and ceremonial locales, trading expeditions, and possibly some warfare are reflected by the numerous trail systems throughout the Colorado Desert. Pot drops, trailside shrines and other evidence of transitory activities are associated with these trails. Many of the pictographic, petroglyphs, and bedrock grinding surfaces in the Colorado Desert have also been associated with the Patayan pattern, although direct dating and cultural affiliation of such features is often difficult.

Ethnohistoric Period
Cahuilla and related Takic ("Shoshonean") speakers of the Uto-Aztecan linguistic stock such as the Luiseño, Serrano, and Gabrieleño, migrated from the southern Great Basin into California to displace the groups who had been occupying those territories. Those displaced groups are presumed to be the ancestors of the modern Hokan speakers who now occupy the areas to the

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-4
south (Kumeyaay) and the north (the Chumash). The specific time, duration, and process of this migration remains unclear. Some estimates based on glottochronology and distribution of archaeological assemblages put the transition somewhere between 1000 to 2000 B.P., mostly likely around 1500 B.P. but possibly as early as 2500 B.P.

The first documented description of Cahuilla Indians is provided by the chroniclers of the Anza Expeditions, whose mission was to bring colonists from Sonora to coastal California Their first trip brought them through Cahuilla territory in March 1774, the second in December 1775. Their first substantive encounter was at San Gregorio in the Borrego Valley, where they found Cahuilla ("Jecuiche") in apparent co-residence with Kumeyaay ("Cajuenches"). They continued to encounter Cahuilla through lower Collins Valley, Coyote Canyon, Cahuilla Valley, Tripp Flats, on the western side of the San Jacinto Mountains. Their observations were few but included references to the early spring agave harvests, seed gathering with beater and basket, rabbit sticks, agave fiber capes, and bows and arrows. Although possibly Serrano, a rockshelter composed of boulders and covered with brush is also described. The Spaniards describe the Cahuilla as weary of their presence, suggesting little or no previous contact, and apparently undergoing food stress, especially during the winter of 1775–1776 visit. This might be expected if stored foods in fall had been depleted and prior to the agave harvest.

The distance of Cahuilla territory from the California missions, first founded in 1769, meant they were not recruited in as great numbers, nor assimilated as rapidly as the coastal tribes. The first to enter Mission San Gabriel, possibly as early as 1783, were western Cahuilla of the kupakik lineage at Warner's Hot Springs. Next were Cahuilla wives of Serrano in the Cajon Pass area in the 1796. Members of western Cahuilla villages first appear in baptism records of 1797. In addition, runaway neophytes, especially Serrano, sought refuge among the desert tribes, exposing more isolated Cahuilla to mission ideology and material culture, not to mention diseases. It is not until after 1810, however, that Cahuilla individuals begin to appear in more substantial numbers in the registers of Mission San Gabriel, San Juan Capistrano, and San Luis Rey.

The impact of the Spanish mission system and colonization was generally much less immediate and profound to the isolated desert and mountain groups than coastal groups. More direct influence was not felt until after the establishment of the San Bernardino estancia in 1819 and, thereafter, a cattle ranch at San Gorgonio. When the Romero Expedition passed though the area in 1823–1824, it was clear that non-missionized Cahuilla were used to seeing vaqueros, employed by the rancho, driving cattle through the area. Certainly by 1823–1824, they were not only familiar with Hispanic ways but were comfortable in dealing with them, as evidenced by their reaction to the members of the Romero Expedition. The expedition also reported that the Cahuilla at Toro were engaged in agricultural pursuits (growing corn and melons) and were already familiar with the use of horses and cattle. While the Cahuilla may have already had some

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-5
experience in cultigens from their contact with the Colorado River tribes, agriculture probably became a more important supplement to their hunting and gathering economy after their exposure to ditch irrigation methods at the missions. Irrigation ditches were certainly being constructed by the Cahuilla in the Palm Springs area by the 1840s, and possibly several decades earlier.

Cahuilla political leadership with regard to external relations became more centralized in the Spanish and Mexican periods as high ranking or charismatic clan leaders were recognized by Europeans as representing entire tribal areas (Strong 1929:149). Emerging as central figures were Juan Antonio among the Mountain Cahuilla and Chief Cabazon in the desert. As early as 1844, Juan Antonio led several mountain clans to the San Gorgonio pass area to provide security for San Bernardino Rancho. His group played a significant role during the Mexican-American War, siding with the Mexicans against the Luiseño who supported the American invasion.

The 1848 Treaty of Hidalgo with Mexico obligated the Americans to preserve the liberty and property of the inhabitants of California, an obligation that obviously failed. The U.S. government in 1850 appointed three commissioners to conduct negotiations with tribal leaders across California to settle all land rights issues. One of the 18 treaties to be drafted covered the Cahuilla, Serrano, and Luiseño and was signed in Temecula on January 5, 1852. The tribal leaders were promised supplies, food, and technical training in return for accepting specified reservation lands. But as was so often repeated throughout the west, local Euro-Americans lobbied against the treaty and Congress never ratified it. The effect was to further alienate the traditional territorial base of the Cahuilla as whites flooded into the area to claim the best farming and grazing lands. Outside the reservations, Cahuilla men and women sought wage work on ranches in the San Jacinto and Santa Rosa mountains, and on farms, orchards, and urban households in the Riverside and San Bernardino valleys. This greatly accelerated the process of acculturation and Cahuilla participation in the regional socio-economic milieu.

European diseases were probably beginning to take their toll on the Cahuilla in the early 1800s but became particularly severe in the 1860s. The most dramatic was the great smallpox epidemic of 1863 that killed Juan Antonio as well as many bearers of tribal wisdom and culture. Survivors of previously autonomous clans assembled into the remaining villages or founded new settlements in an accelerated process of population aggregation and cultural reorganization. This process continued through the following decades. Isolated canyons now became places of refuge from disease and from contacts with Euro-Americans in general. Many previously occupied areas were abandoned in the 1860s and 1870s as residential bases but were still used for hunting and gathering into the twentieth century.

The Cahuilla land base was substantially reduced in the 1860s and 1870s as the federal government ceded every other section within ten miles of the new transcontinental railroad to the

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-6
railroad companies. Sections 16 and 36 of every township were also removed from federal control as a school tax base. Any de facto control of larger territorial bases was completely eliminated in 1876 when President Grant by Executive Order set aside small reservations for all groups classified as "Mission Indians." This included the sections or parcels in which they had aggregated in the previous decades and in which they had made improvements for farming, etc.

The following year, another Executive Order by President Hayes set aside every even numbered section and certain other unsurveyed portions of townships for Indian reservations. The result was a checkerboard of Indian-controlled land, encompassing 48 sections, spread across the eastern edge of the Santa Rosa and San Jacinto mountains and the Coachella Valley. With various additions and withdrawals over time, this has remained the permanent home of the Cahuilla to the present.

As traditional lifeways became more difficult to pursue, the Cahuilla adapted to their new geographical and political environment by taking jobs in American ranches, towns, and cities.

The 1860s through 1880s was a time of increased acculturation as new technologies, material goods, and practices were incorporated into the traditional lifeways of the reservation.

Traditional ceremonial practices and beliefs continue along side Catholic and Protestant beliefs for many Cahuilla. Ceremonial houses still existed through the 1950s, 1960s, and early 1970s and many cultural traditions remain part of westernized lifestyles. The Cahuilla retain an acute interest in their cultural heritage and the cultural resources of their traditional territories.

Record Search Results
One historic resource was identified within the project area. The site is a bungalow style home located in the south-central portion of the project area adjacent to other existing buildings. The house was first recorded in 1982 by Laura Swift of the Riverside County Historical Commission.

In addition to onsite resources, five previously identified resources were identified within one mile of the site. Two of the resources are historic structures associated with farming in the area.

One resource is the former location of historic structures and a Mission-era adobe rancho built around 1820. Another resource consists of the Colorado Aqueduct. The Aqueduct was built from 1933 to 1928 to transport water from the Colorado River to the Los Angeles Basin. One resource is the location of a historic event, the landing site of a record-setting trans-polar flight. This occurred on July 14, 1937, when a crew of three Russians landed their ANT-25 plane in agricultural fields after low fuel and fog forced them to abandon an attempted landing at San Diego. The 6,295-mile flight set a distance record and was only the second to cross the North Pole. The flight began in Moscow and lasted 62 hours, 2 minutes.

Site Survey Results
The site survey resulted the discovery of two isolated prehistoric artifacts. One previously recorded historic structure also exists within the project area. These resources include:

Historic Structure
The historic structure is a single-family home first recorded in 1981 by Laura Swift of the Riverside County Historical Commission. Swift estimated that it was built around 1926.

However, a structure appears at the location on 1901 30-minute quadrangle maps. It is possible that the current home replaced an earlier structure. Evidence of such a replacement was not noted during the field survey.

The house is a front-gabled craftsman-style bungalow with a partial width front porch. The porch is also front gabled and both porch and house gable have triangular slatted vents under the gables. The front porch is enclosed by a low wall and rounded pilasters support the porch roof.

The roof has widely overhanging eaves with exposed beams and triangular knee braces. The windows are all wood-framed double hung sashes with wooding casing.

The house has been abandoned since first recorded and is no longer maintained. It lies directly on an active fault (Casa Loma Fault) and the northeast corner has subsided 2-4 inches producing cracks on interior walls. All kitchen and bathroom cabinets, facilities and appliances were replaced, probably in the 1970s. Minor remodeling to interior spaces and partitions has also occurred. The north half of the attic was converted into a small bedroom loft with modern faux wood paneling. A small storage cellar is also located under the north half of the structure and is accessible by a stairwell in the kitchen. The unusual arrangement of windows on the north face of the house suggests other alterations may have occurred. Based on photos of the house taken during the original site survey (November 2004), the structure has further deteriorated with most of the windows being broken out and being marked with extensive graffiti.

One outbuilding which probably served as a tractor shed or garage was noted in the original field survey, but is no longer present at the site.

ISO-1 (Isolated Bifacial Mano)
An isolated bifacial mano (hand-held milling stone) was found near the crest of a subtle escarpment formed by an active fault that crosses the San Jacinto Valley. The floodplain of the San Jacinto River lies north of the escarpment. Otherwise, the area would have been a featureless alluvial plain in prehistory. The mano measures 10×8.2×5.7 cm and is made of coarse-grained granite. Both ends have been battered either to shape the mano into a desirable form or by being used as a pestle.

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-8
ISO-2 (Isolated Bifacial Mano)
An isolated bifacial mano (hand-held milling stone) was discovered 36 m south of ISO-1. The mano measures 8.5 cm in diameter and is 5 cm thick. It is made of hard, semi-crystaline quartz.

About 70% of the circumference has been battered, probably to shape the object.

Despite good ground visibility and extensive searching, no additional artifacts were found in the vicinity of the two manos.

5.5.3 Significance Thresholds
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on cultural resources if it would:

1. Cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5?

2. Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 10564.5?

3. Disturb any human remains, including those interred outside of formal cemeteries? NOTE: Due to the length of CEQA Section 15064.5, it is not repeated verbatim. Please refer to www.ceres.ca.gov for a description of CEQA Section 15064.5.

5.5.4 Impacts
The following discussion outlines potential impacts for the proposed project.

Would the project cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5?
While the historic structure has many features of a Craftsman-style bungalow, it has been substantially altered. All cabinets and plumbing fixtures have been destroyed. Interior walls have been altered by graffiti and many parts of the walls and ceiling have been punctured with holes that are beyond repair. The original wooden siding has been replaced by unusual textured pink stucco. In addition, a corner picture window has been inserted at the rear of the house.

The importance of a historic structure is related to survival of characteristics that existed during the period of significance. Historical resources must retain enough of their character or appearance to be recognizable as historical resources and to convey the reasons for their significance. Integrity is evaluated with regard to the retention of location, design, setting, materials, workmanship, feeling and association. The bungalow has been altered to the extent

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-9
that it has lost integrity of design, materials, workmanship and feeling. In fact, it is now barely identifiable as a Craftsman-style bungalow. It is unlikely that the bungalow retains sufficient integrity to be eligible for listing on the California Register of Historical Resources. Therefore, a less than significant impact to this formerly historic resource would occur.

Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 10564.5?
No significant archaeological resources were identified within the project by either a records search or survey. One previously recorded historic structure and two newly identified isolated prehistoric artifacts were identified by the survey. Five previously recorded sites are located within one mile of the project. Due to the presence of these resources and the fact that the project is located within an alluvial setting, potentially significant archaeological resources could be unearthed during site grading. In order to reduce this potentially significant impact from occurring, mitigation is provided (see Section 5.5.5, Mitigation Measures, Mitigation Measure 5.5-a).

Would the project disturb any human remains, including those interred outside of formal cemeteries?
There are no known human remains within the site or vicinity. Additionally, the Native American Heritage Commission (NAHC) conducted a search of their Sacred Lands File, but found that Native American cultural resources were not present within one-half mile of the project area (See Appendix B). However, in the unlikely event human remains are found during construction activities, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur in the immediate area until the County Coroner has made the necessary findings as to origin and disposition pursuant to Public Resources Code Section 5097.98. If the coroner recognizes the human remains to be those of a Native American, or has reason to believe that they are those of a Native American, he or she shall contact, by telephone within 24 hours, the NAHC who will then contact the appropriate tribal representative. Should local Native American groups find that the site supports potential buried ancestral remains, the Soboba Consulting Services Agreement allows for Native American monitoring during construction.

Consequently, the project’s adherence with the State Health and Safety, Public Resources Codes and Soboba Consulting Services Agreement shall ensure any potential impacts would be less than significant.

5.5.5 Mitigation Measures

5.5-a In order to reduce the potential for disturbance or damage to unknown archaeological resources, monitoring of mass grading activities of the site by a qualified archaeologist is required. Should the monitor observe disturbance of resources that could be important

5.5 CULTURAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.5-10
archaeological artifacts, the monitor shall have the power to stop grading in the immediate area of discovery in order to allow for a resource study and recovery/curation effort (if necessary) to occur.

5.5.6 Residual Impacts/Level of Significance after Mitigation Due to the lack of significant historic resources present, significant impacts would not occur. In order to reduce potentially significant impacts to unknown archaeological resources, mitigation is provided and would reduce any potentially significant impacts to a level below significance.

5.6 GEOLOGY AND SOILS

5.6 GEOLOGY AND SOILS

5.6.1 Introduction/Methodology
This section consists of a summary of existing geological conditions, anticipated impacts related to these conditions and mitigation measures required to reduce these impacts to a level below significance. A residual impact statement has been included to characterize the level of significance after applied mitigation measures.

A fault investigation for the project was performed by Leighton and Associates and their preliminary findings are presented in their report dated March 31, 2004. In order to evaluate the potential for surface fault rupture in the existing onsite Earthquake Fault Hazard Zone, ten exploratory fault trenches were excavated over a period of seven months. Findings were coordinated and reviewed with the County of Riverside Geologist and previous investigations completed on adjacent sites were also reviewed. In response to questions and comments received from the County Geologist, Leighton also prepared three additional investigations (reports dated August 31, 2005, June 30, 2006, and October 31, 2006). These investigations are included in Appendix E of this EIR and summarized in this section. Leighton and Associates conducted a preliminary geotechnical investigation which is summarized in the February 28, 2005, Preliminary Geotechnical Investigation. This second report is included as Appendix F to this EIR.

5.6.2 Existing Conditions
Subsurface Soil and Rock Conditions
The earth materials encountered throughout the site consist of undocumented fill, topsoil and alluvium. These units are described in the following sections in order of increasing age.

Undocumented Fill
Undocumented fills are related to grading activities to construct onsite access roads, perimeter unimproved dirt roads, site agricultural leveling and exploratory excavations (fault trenches).

Other undocumented fills exist associated with limited water retention berms to collect seasonal runoff and the livestock run-off retention basin. All undocumented fills are considered unsuitable for support of additional fill or structures or other planned improvements in their present condition.

Topsoil
The majority of the site is composed of topsoil that is located on the upper 10 to 24 inches of the ground surface. Uniform in composition and thickness, this material general consists of a light

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01
August 2009 5.6-2
yellow-brown to yellow brown, silty sand, silty clay to sandy clay with scattered gravel sized clasts.

Alluvium (Qal)
Alluvial soil was encountered in all areas of the site and was deposited as part of a complex fluvial/channel dispositional environment. This alluvium consists of yellow-brown to medium gray, dry to damp, silty, very fine to fine sand, with interbedded lenses of silt. Channel deposits of homogeneous, friable, dry, medium to coarse sand with interbedded lenses and lamination of gray, loose to medium dense, dry to damp, very fine to fine sand were also observed. There are abundant in-filled animal burrows containing finer silt and sands.

Subsurface Water Conditions
Perched groundwater was encountered at multiple depths below the surface, as shallow as 5 feet and as deep as 22 feet. Regional groundwater is anticipated below 150 feet and likely, as much as 200 feet below grade. However, groundwater can be expected to fluctuate seasonally within the subject site and during periods of heavy regional rainfall, or groundwater withdrawal by the local residences, agricultural developments and water utility companies. During drought conditions, groundwater levels could temporarily deepen significantly.

Faulting and Seismicity
Based on the commonly accepted definition provided by the California Geological Survey, an "active fault" is a fault that has had surface displacement within Holocene time (about the last 11,000 years) and a "potentially active fault" is a fault considered to have had surface displacement during Quaternary time (last 1,600,000 years). These definitions are used in delineating Earthquake Fault Zones as mandated by the Alquist-Priolo Geologic Hazards Zones Act (California Public Resources Code Sections 2621–2630). The intent of this act is to prohibit the location of structures on the traces of active faults, thereby mitigating potential damage due to fault surface rupture.

The project site is located within seismically active southern California. The subject site contains an Earthquake Fault Zone (as created by the Alquist-Priolo Earthquake Fault Zone Act).

According to the Leighton & Associates Fault Investigation, the active San Jacinto-Casa Loma fault transverses the northwestern and southern portions of the project site. Fault lineaments are shown by geomorphic evidence, aerial photography, and in the San Jacinto 7.5 minute Quadrangle of the Alquist-Priolo Earthquake Fault Map (see Figure 5.6-1, Faults and Fault Zones).

In addition to the on-site Casa Loma, several other active faults are located in the project area.

The San Jacinto Valley Segment of the San Jacinto Fault is located approximately 0.8 mile northwest of the site, the San Jacinto-Anza Fault is located 7.2 miles to the southeast, and San Andres Fault lies 15.7 miles to the northeast. Figure 5.6-1 summarizes regional faults within the area. The San Jacinto Fault Zone is estimated to accommodate a plate slip of approximately 12– 20 millimeters per year. Since the mid-18th century, at least six major earthquakes have occurred along the San Jacinto Fault Zone, ranging from 6.2Mw to 7.2Mw. Of all the fault systems in California, the San Jacinto and San Andreas Fault complexes are among the most active. The U.S.G.S. measures hundreds of minor earthquakes annually within the San Jacinto Valley. Most of these earthquakes are in the bedrock underlying the alluvium unit at depths of 3 to 5 miles.

Subsidence/Ground Rupture
Ground rupture is generally considered most likely to occur along pre-existing active faults. As such, the potential for site ground rupture during a seismic event is considered moderate to high.

Based on historic occurrence data, ground rupture is believed to occur at normal recurrence intervals which may not provide adequate time for erosion to conceal fault features.

Subsidence/rupturing of a portion of the San Jacinto graben has occurred at an apparent average rate of between 0.125 and 0.5 inch per year for at least the past 15,000 to 40,000 years (see Figure 5.6-2, Subsidence Hazard Areas).

Liquefaction
Liquefaction occurs when strong seismic activity creates excess pore pressures in cohensionless soils. Research and historical data indicate that loose granular soils or soils of low plasticity below a near surface groundwater table are most susceptible to liquefaction. Liquefaction is characterized by a loss of shear strength in the affected soil layers, thereby causing the soil to flow as a viscous liquid. This effect may be manifested at the ground surface by settlement and/or sand boils. In order for the potential effects of liquefaction to be manifested at the ground surface, the soils generally have to be granular or of low plasticity, loose to medium dense, saturated relatively near the ground surface and must be subjected to a sufficient magnitude and duration of ground shaking. Increased soil mobility can lead to lateral spreading, consolidation and settlement of loose sediments, ground oscillation, flow failure, loss of bearing strength, ground fissuring and other damaging formations. As depicted on Figure 5.6-3, Liquefaction Hazard Areas, the proposed project is located in an area with moderate potential for liquefaction.

Upon further analysis, the Leighton Associates Report identifies the northern one-third to one half of the project site as having a potentially high possibility for liquefaction to occur given current site conditions.

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01
August 2009 5.6-6
Landslide, Mudflow or Other Erosion Hazards
Landslides are anticipated when severe weather events weaken certain agglomerations of hillside soils. As a result, unstable soil slips downhill. The proposed site is relatively flat with site elevations varying from approximately 1,457 feet above mean sea level along the northwestern boundary to an elevation of approximately 1,493 feet near the southeast corner. No previous landslides were identified during the investigation (see Figure 5.6-4, Landslide Hazard Areas).

Similar to landslides, mudflows occur during severe weather events in or adjacent to mountainous terrain. Large boulders and sediment are mobilized as a result of a sudden onslaught of water. This hazard is prone to occur in areas affected by fire that are relatively void of vegetation. The project is located in the San Jacinto River Valley, away from mountainous terrain. This hazard is expected to be minimal at this project site.

Any exposed soil surface may be susceptible to wind or water erosion. There are no naturally occurring drainages on site, therefore the likelihood of water-based erosion is unlikely.

Seiches and Tsunamis
A tsunami is a sea wave generated by submarine earthquakes, landslides or volcanic activity, which displaces a relatively large volume of water in a very short period of time. Seiches are defined as oscillations in a semi-confined body of water due to seismic shaking. The proposed project site is not located near a significant body of water or the Pacific Ocean. Therefore, these hazards are not anticipated at the project site.

5.6.3 Significance Thresholds
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on geology and soils if it:

1. Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving:
a. Rupture of a known earthquake fault, as delineated in the most recent AlquistPriolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault
b. Strong seismic ground shaking
c. Seismic-related ground failure, including liquefaction d. Landslides.

2. Result in substantial soil erosion or the loss of topsoil.

3. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse.

4. Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property.

5. Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water.

5.6.4 Impacts
Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving:

Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.

Potential site ground rupture, as determined by the Leighton and Associates Fault Investigation, is considered moderate to high. Ground rupture due to onsite faults could potentially affect existing and future facilities (such as gas, electrical, water mains, etc.) that traverse fault zones on the site. In order to mitigate for potential impacts associated with seismic ground shaking, mitigation is provided (see Section 5.6.5, Mitigation Measures, Mitigation Measure 5.6-c).

Strong seismic ground shaking?
The project site is located in seismically active southern California with numerous fault systems in the region. Structures will be designed in accordance with the values and parameters given within the Universal Building Code (UBC) as required by state law. With the incorporation of UBC seismic design parameters in construction of structures on site, the impacts associated with exposure of people to geological hazards is less than significant. These measures are a standard part of the Building Permit process and additional mitigation measures are not required.

Seismic-related ground failure, including liquefaction? Liquefaction potential analyses and earthquake-induced settlement calculations were performed utilizing the computer program LiquefyPro. Considering the potential ground motions resulting from the design basis ground motion (0.9g) and a maximum moment magnitude event for the

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01
August 2009 5.6-14
San Jacinto Fault (6.9Mw), the program follows the latest study procedures. Leighton used the boring data, CPT data and groundwater data (perched groundwater table ranging from 5 to 22 feet) as assumptions in the model.

Based on the above-described model, the relatively loose saturated alluvial deposits onsite are considered susceptible to liquefaction hazards. Liquefaction occurs when loose material becomes mobile during a seismic event. In order to compensate for hazards associated with liquefaction, mitigation is provided (see Section 5.6.5, Mitigation Measures, Mitigation Measures 5.6-b and 5.6-e). With implementation of these measures, liquefaction potential for the project will be less than significant.

Landslides?
Due to the flat nature of the site and the existing topsoil and Quaternary-aged alluvium, the subject site is not prone to landslide hazards. That said, manufactured slopes that are planned for construction on the site would be susceptible to slope stability hazards. In order to prevent any significant impacts from occurring, mitigation is provided (see Section 5.6.5, Mitigation Measures, Mitigation Measure 5.6-f).

Slopes adjacent to severe flow direction changes may be susceptible to increased scour erosion and slope stability. In order to reduce this potential impact to a level below significance, mitigation is provided (see Section 5.6.5, Mitigation Measures, Mitigation Measure 5.6-g).

Would the project result in substantial soil erosion or the loss of topsoil? Short-term erosion effects during the construction phase of the project would be minimized through implementation of the City of San Jacinto construction Best Management Practices (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-d) Would the project be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or offsite landslide, lateral spreading, subsidence, liquefaction, or collapse?
The volume change of excavated onsite materials upon recompaction is expected to vary with materials, density, moisture content, location and intended compaction effort. This variance in material could potentially result in shrinkage, which would result in potential subsidence risk. In order to reduce potential impacts to a level below significant, mitigation is provided (see Section

5.6.5, Mitigation Measures, Mitigation Measure 5.6-d and 5.6-e).

Many portions of the site are characterized as having unsuitable near surface compressible soils not suitable for structural support. Location of a structure on an unstable geological unit or soil

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01
August 2009 5.6-15
would be a significant impact; thus, mitigation is provided (see Section 5.6.5 Mitigation Measures, 5.6-a).

Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Expansive soils are those with a significant amount of clay particles that have the ability to shrink or swell depending on water content. The Geotechnical Report indicated that based on limited laboratory testing and visual classification, onsite earth materials generally possess a very low to medium expansion potential; however, high to very high expansive silt and clay materials may be encountered locally during rough grading. Compliance with recommendations for ground preparation as outlined in the February 28, 2005, Leighton and Associates Geotechnical Investigation will reduce risk hazards associated with expansive soils to a less than significant level.

Would the project have soils incapable of adequately supporting the use of septic tanksor alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?
No septic tanks or alternative wastewater disposal systems are proposed as part of the project. As a result, no impact would result.

5.6.5 Mitigation Measures

Fill soils will be placed and compacted to a minimum 92 percent relative compaction at a minimum of 2 percent above the optimum moisture content.

Fill slopes shall be overbuilt a minimum of 2 feet and trimmed back to the compacted core or rolled with a weighted sheepsfoot compaction roller as the fill slope height increases in maximum 4-foot increments. Placement and compaction of fill shall be performed in accordance with City grading ordinances and minimum compacted standard under the observation and testing of a qualified geotechnical engineer.

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01

anticipated conditions, further investigations and/or additional structural setbacks can be required.

5.6-b To facilitate the grading operations, on-site irrigation water shall be reduced or ceased for a period of 3 to 6 months prior to the start of grading. Further, the contractor will pothole the upper 12 to 14 feet of soil prior to the start of grading operations to determine if shallow groundwater will affect the planned grading.

In localized areas where shallow groundwater conditions exist such that removals cannot be performed to the required depths or where deeper excavations (such as in the proposed “lake” areas) are proposed at or below the existing perched groundwater, methods of localized dewatering will be required including the use of well points and/or interceptor ditch methods. Alternative ground stabilization methods such as deep dynamic compaction shall be required. Deep dynamic compaction is a means of physically compacting the subsurface soils by repeatedly dropping a heavy weight (typically a large concrete block) to densify the underlying soils to a predetermined density. After proposed grading plans are developed, these areas shall be further reviewed by a qualified geotechnical engineer.

5.6-c A structural setback zone of 50 feet on either side of the encountered fault zone, and as much as 75 feet on the “down-block” side shall be observed for structures intended for human occupancy (2,000 hours/year). This preliminary setback zone will be refined as the grading concept is developed and possible additional site studies are performed. The Fault Location Map (Plate 2) within the Fault Investigation shows required preliminary structural setbacks. However, the final setback limits shall be determined during grading or future studies as the fault trace is exposed, identified and surveyed for lateral and vertical location. The setbacks shall be shown on all project plans.

To reduce the effects and magnitude of the earthquake-induced settlements, remedial grading shall occur. Following remedial grading, differential dynamic settlements are anticipated to be approximately 2 inches in a horizontal distance of 40 feet. Additional analysis will be performed by a qualified geotechnical specialist to further refine earthquake-induced settlement. Based on a review of the rough grading plans by a qualified geotechnical specialist, remedial grading requirements will be revised.

To reduce the potential adverse secondary seismic effects, mitigation of compressible alluvial soils to support the planned development at areas such as free-face slopes ("green belt" detention basins, channels etc.), the project perimeter (where removals may be limited by property restraints) and planned lake areas will require additional geotechnical stability design by a qualified geotechnical engineer after project plans are developed.

5.6-d While it is difficult to determine the level of subsidence and shrinkage risk, site grading must include a balance area or ability to adjust import quantities to accommodate some variation. Relative compaction rates must be followed as they appear in the February 28, 2005, Leighton and Associates Technical Report. As stated in the February 28, 2005, Leighton Report, due to the agricultural discing of the surface soils, a subsidence value of

0.2 feet must be applied when evaluating earthwork volumes.

5.6-e To reduce the potential for liquefaction and earthquake-induced settlements at the site, the following guidelines will be implemented. For preliminary design purposes, a minimum removal and recompaction of 10 feet (as measured from finish grade) will be used in cut areas on that portion of the site designated as having a high potential for liquefaction (roughly the northern one third to one half of the site).

In cut areas outside the area designated as high potential for liquefaction, a minimum overexcavation of 5 feet below finish grade must be used. For areas designated as “fill” a minimum removal of 5 feet will be used, provided a minimum total thickness of 10 feet of properly compacted fill is maintained below the lowest adjacent finish grade (including lowest adjacent street elevation). The removal depths for the infrastructure roadways shall be a minimum 5 feet below pavement subgrade. These estimates are for preliminary design planning only and will be revised based on our review of rough grading plans. These preliminary estimates will be revised upon review of the proposed grading concept plan. These alluvial soils must be removed down to medium dense to dense, relatively non-porous alluvium material as determined by the geotechnical consultant. Undercuts will be made 1:1 next to existing roadways that will remain after grading. Cut slopes shall be replaced as properly compacted fill.

The excavated materials will be moisture conditioned or dried back, as appropriate, to achieve the required minimum relative compaction. Saturated soils may need to be dried back or mixed with drier on-site materials and shall be thoroughly mixed prior to fill placement. The resultant excavation will be filled and compacted in this lifts to a minimum 92 percent relative compaction at a minimum of 2 percent above the optimum moisture content. A minimum 90 percent relative compaction may be acceptable in the southern portion of the site. This will be determined during review of rough grading plans.

5.6 GEOLOGY AND SOILS
Villages of San Jacinto EIR 4307-01
August 2009 5.6-20
After completion of the required removal of unsuitable soils, the approved surface will be scarified, moisture conditioned as needed and compacted prior to placing fill. If subgrade conditions at the approved bottoms are wet and “pumping” near the required removal depth, the scarification and moisture conditioning will not be necessary. Stabilization measures where shallow groundwater conditions are expected at or near the required removal depth may include the use of a stabilization fabric and/or coarse gravel/graded rock and gravel. Where shallow groundwater conditions are present, alternative ground improvement guidelines shall be followed (see Mitigation Measure 5.5-b). Further evaluation of these specific areas will be necessary after draft grading plans are prepared.

5.6-f All slopes will be provided with appropriate surface drainage features and landscaped with drought-tolerant, slope-stabilizing vegetation as soon as possible after grading to reduce the potential for erosion. Berms will be provided at the top of fill slopes to direct water away from slope faces. Lot drainage shall be directed such that runoff on slope faces is minimized. Oversteepening of slopes must be avoided during fine grading and building construction. Although not anticipated, if seepage is encountered in slopes, special drainage features may be necessary.

5.6-g For slopes that are will be adjacent to ditches or other water conveyance features, proper protection including rip rap or other slope protection devices as designed by the project civil engineer would be required. Slope stability and the potential for scour shall be required in the design drainage alignment.

5.6.6 Residual Impacts/Level of Significance After Mitigation The mitigation measures, which include further monitoring of onsite geotechnical risk as grading plans are finalized for a qualified geotechnical engineer, would reduce impacts related to geology and soils. All mitigating geotechnical features shall be designed/implemented pursuant to the Uniform Building Code and State of California seismic engineering standards. These mitigation measures will therefore reduce geotechnical hazards to less than significant levels.

5.7 PALEONTOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.7-1

5.7 PALEONTOLOGICAL RESOURCES

5.7.1 Introduction/Methodology
This section presents a discussion of paleontological resources that would be affected by the proposed project and alternative. Paleontological resources are the fossil or trace remains of past life forms, including both vertebrate and invertebrate species, as well as plants. Fossil remains such as bones, teeth, shells, leaves, etc. are found in the geologic deposits (formations) within which they were originally buried. The geologic composition of an area; therefore enables scientists to evaluate the potential for resources to occur, based on knowledge of resources that have been uncovered from similar geologic formations elsewhere.

Existing condition information is derived from the February 28, 2005, Leighton and Associates, Inc. Preliminary Geotechnical Investigation for the Villages of San Jacinto project. This report is included as Appendix F to this EIR. Methods utilized in the February 28, 2005, Leighton Report are contained therein. Paleontological sensitivity data was obtained from the 2003 Riverside County General Plan Update Multipurpose Open Space Element.

5.7.2 Existing Conditions
Sediments derived from the San Jacinto River have been deposited across the river valley. The sediment thickness is thought to be highly variable with a minimum thickness of 500+ feet in the southwest portion of the valley. Paleoeustuary silts and sands, Quaternary-aged terrace deposits and fanglomerates flank major abandoned drainage channels and the base of mountain slopes.

Near the City of San Jacinto, a boring excavated northeast of the Casa-Loma Fault segment did not reach basement rocks to the depth explored of 1,430 feet. In general, seismic and gravity surveys indicate that approximately 6,500 feet to 7,900 feet of alluvial sediment overlie the basement bedrock in the valley.

As indicated on Figure OS-8 of the 2003 Riverside County General Plan Update Multipurpose Open Space Element, the project is located within an area characterized as having a high likelihood of supporting fossils (see Figure 5.7-1, Paleontological Sensitivity). The San Jacinto Valley is designated as "High B (Hb)" which means a resource's probability to occur is based on the occurrence of fossils at a specified depth below the surface. This category indicates that fossils are likely to be encountered at or below four feet of depth and may be impacted during excavation by construction activities (County of Riverside, 2003, pg. OS-36 to OS-37, Figure OS-8).

5.7 PALEONTOLOGICAL RESOURCES
Villages of San Jacinto EIR 4307-01
August 2009 5.7-2

5.7.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on paleontological resources if it:

1. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature.

5.7.4 Impacts
Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
Since the proposed project lies within a geologic formation with high resource bearing potential and the project would necessitate recompaction of potential fossil bearing alluvium, impacts to paleontological resources are considered to be significant. Impacts to paleontological resources could occur during excavation and site development when geologic formations that have resource bearing potential are disturbed. Impacts would occur when fossils are physically destroyed by such activities. In order to reduce potential construction-related impacts to paleontological resources, mitigation is provided (see Section 5.7.5, Mitigation Measures, Mitigation Measure 5.7-a).

5.7.5 Mitigation Measures

5.7-a Prior to beginning any excavation work, the developer or its contractor shall demonstrate that a qualified paleontologist has been retained to carry out a paleontological resources mitigation program. A paleontological monitor shall be on site at all times during grading activities that disturb non-undocumented fill soils or formations. If fossils are discovered, the paleontologist or paleontological monitor shall have the authority to halt construction in the immediate area of discovery until such a time that a complete assessment of the resources can be conducted. If resources are found that are determined to be significant, the paleontological monitor shall direct activities to recover the resources. Prepared fossils, along with copies of all pertinent field notes, photos and maps shall be deposited in a scientific institution with paleontological collections, such as the San Bernardino County Museum.

5.7.6 Residual Impacts/Level of Significance after Mitigation With the implementation of the construction monitoring program (outlined as Mitigation Measure 5.7-a, above), impacts to paleontological resources would not be significant.

5.8 WATER QUALITY AND HYDROLOGY

5.8.1 Introduction/Methodology
This section consists of a summary of existing hydrologic conditions, anticipated impacts related to these conditions, and mitigation measures required to reduce these impacts to a level below significance. A residual impact statement has been included to characterize the level of significance after applied mitigation measures.

This analysis is based on information contained in the February 2009 Villages of San Jacinto Specific Plan, Drainage Plan by T&B Planning Consultants; the May 2006 Preliminary Drainage Study for Tentative Tract Map 34081 by RBF Consulting; the August 2006 Phase 1 and 2 Preliminary Drainage Study for Tentative Tract Map 34081 by RBF Consulting; the January 15, 2007, Summary Preliminary Drainage Analysis for TTM 34081 Phases 1, 1A, 1B & 1C by RBF (included as Appendix G to this EIR); and the February 23, 2009, Preliminary Hydrology and Hydraulics Study for the Villages of San Jacinto by JLC Engineering & Consulting Inc. Floodplain resource information was obtained through the September 7, 2006, letter from RBF to Riverside County Flood Control and Water Conservation District. Water quality management information was obtained from the February 23, 2009, Preliminary Hydrology and Hydraulics Study referenced above and the Lake Preliminary Design Report (Pacific Aquascape, Inc. March 2009). Additional hydrologic resource setting and existing conditions information was used from the February 28, 2005, Leighton and Associates Geotechnical Investigation for the proposed project (included in Appendix F to this EIR); discussions with Leighton and Associates geotechnical staff; and publications by the Santa Ana Regional Water Quality Control Board (RWQCB) (1995, 2003, 2004). Once existing condition information was summarized, the City of San Jacinto Significance Thresholds, specifically Hydrology and Water Quality Resource Thresholds, were used to determine if hydrologic impacts were considered significant from a CEQA perspective. Mitigation measures were developed in part by recommendations in the February 2009 Villages of San Jacinto Specific Plan, Drainage Plan Report by T&B Planning Consultants and experience with past projects of a similar size and character.

5.8.2 Existing Conditions
The San Jacinto and broader Inland Empire climate is mild. Winters are characterized as mild and sometimes cool, springs can be rainy, and the summer and fall hot and dry. The San Jacinto area climate is characterized by relatively low rainfall, with warm summers and mild winters.

Annual precipitation averages about 13 inches, with over 70% of that falling between December and March. Average monthly temperatures range from a high of 98° Fahrenheit in August to a low of 37° Fahrenheit in December (City-Data.com, Accessed April 30, 2009).

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-2
The San Jacinto River is the dominant hydrologic feature of the central western Riverside County area. Rainwater and urban runoff drain through a series of reservoirs, canyons, and/or storm drain facilities into this drainage system. This hydrologic feature runs along the northern and eastern edge of the City (see Figure 5.8-1, Existing Hydrologic Features).

5.8.2.1 Surface Water
The main surface hydrologic feature of the San Jacinto Valley is the San Jacinto River. This waterway is a natural channel that has been disturbed by historical filling and farming activities.

This river flows from east to west and serves as the main drainage point for precipitation runoff from higher elevations to the east and urban runoff throughout the watershed.

Within the river valley, various channels and ephemeral creeks feed the river system. This watercourse is located approximately 1 mile northeast of the project site. General off-site drainage occurs through a northern sheet-flow pattern off the project site toward the San Jacinto River. Surface water runoff often ponds on site and throughout the river plain to form an alkali playa hydrologic feature. Currently, on-site water drains in a sheet flow manner to the north toward the San Jacinto River. On-site irrigation channels also assist in drainage of the site.

5.8.2.2 Groundwater
Groundwater is defined as subsurface water that exists in soils and geologic formations that are fully saturated. The water table is considered to be the top of the saturated zone. Groundwater bearing formations sufficiently permeable to transmit and yield significant quantities of water are called aquifers. The principal groundwater basins in the San Jacinto Region are the Lakeview/Hemet-North, San Jacinto-Upper Pressure, and Hemet-South. The project site straddles the Lakeview/Hemet-North basin to the west and the San Jacinto-Upper Pressure basin to the east. The San Jacinto River had historically kept all the groundwater basins in that part of the region full. Now, there is essentially no surface flow beyond the mouth of the canyon, where it exits the mountains; the riverbed is typically dry (State of California 1995, p. 1-5).

Similar to most Riverside County rivers, the San Jacinto River is supported by a groundwater basin. Groundwater was locally encountered on the site at depths between 5 and 40 feet below existing ground surface elevations. It is suspected that groundwater may be as deep as 200 feet below ground surface on the project site. The groundwater table likely fluctuates seasonally in response to long periods of heavy rainfall or groundwater withdrawal (Leighton 2005, p. 7).

5.8.2.3 Flooding
As depicted on Figure 5.8-1, Existing Hydrologic Features, the northwest corner of the project is located within Zone A of the San Jacinto River, as mapped by the Federal Emergency Management Agency (FEMA). Zone A is defined as the area of the 100-year floodplain with base flood elevations and flood hazard factors not determined.

The San Jacinto River Valley has a very unique flood flow regime. Flood flows every 5 or 10 years have contributed to the broad, shallow "Mystic Lake" in the riverbed north of the City. The shallow, periodic flooding of this river has contributed to the wildlife and alkali-playa-dependent plant species that characterize the area.

5.8.2.4 Water Quality
Water quality refers to the effect of natural and human activities on the composition of water.

Water quality is expressed in terms of measurable physical and chemical qualities that can be related to planned water use. In general, stormwater can potentially contain a host of pollutants, such as trash and debris, bacteria and viruses, oil and grease, sediments, nutrients, metals, and toxic chemicals. These contaminants can adversely affect receiving and coastal waters, flora and fauna, and public health. Water quality issues are especially prevalent during rainy periods; however, due to the amount of urban runoff that is transferred to the storm drain and natural drainage system, pollution is a problem year-round.

Regulatory Background
Several important federal and state legislative actions have an impact on how water quality is measured, controlled, and addressed during the planning process. Important legislation and regulatory mechanisms are therefore outlined below.

Federal Water Pollution Control Act (Clean Water Act)
The basic federal law regulating surface water quality control is referred to as the Federal Water Pollution Control Act of 1972, commonly referred to as the Clean Water Act. The main objective of the Clean Water Act is to "restore and maintain the chemical, physical and biological integrity of the Nation's waters and to make all waters fishable and swimmable." The Clean Water Act established seven goals and guidelines for water quality, including the elimination of pollutants to navigable waters by 1985, provision of quality water to allow for propagation of fish and other marine life, prohibition of pollutants in toxic amounts, provision of financial assistance to waste treatment management plans, development of technology necessary to carry out goals, and development and implementation of programs for control of non-point source pollution. Clean

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-6
Water Act provisions have been written in conjunction with applicable plans and policies of the federal Endangered Species Act and the National Environmental Policy Act.

The Clean Water Act, in part, establishes requirements for state water quality planning, management, and implementation with regard to surface waters. These requirements call for the restoration and maintenance of chemical, physical, and biological integrity of state waters; attainment of a level of water quality that provides for the protection and propagation of fish, shellfish, and wildlife and recreation in and on the water; and consideration of water resources for state water supplies and other beneficial uses. The Clean Water Act requires that the goals and guidelines established by varying state agencies be reviewed on a triennial basis. This process involves public hearings at least once every 3 years for the purpose of review and/or revisions (State of California 1995, p. 1-2).

Other provisions of the Clean Water Act related to basin planning include Section 208, which authorizes the preparation of waste treatment management plans, and Section 319, which mandates specific actions for the control of pollution from non-point sources. 1987 amendments to the Clean Water Act identified the importance of non-point source pollutants and their impact on local water quality. As stated in the Water Quality Control Plan for the Santa Ana River Basin (State of California 1995), non-point source pollutants represent the greatest threat to water quality. Non-point source pollutants are often chemicals from lawns or gardens, automobile residues, urban runoff, or household cleaning agents or compounds. Most non-point source pollutants enter the water supply in large quantities and sudden surges, largely due to storm events. Control of this type of pollution source has proven to be difficult. Because the release of a non-point source pollutant is exempt from National Pollution Discharge Elimination System (NPDES) regulations, the RWQCB has more recently focused on non-point source pollution issues. The RWQCB has encouraged all community members to use best management practices (BMPs) to eliminate or reduce non-point source pollution.

National Pollution Discharge Elimination System (NPDES) NPDES, established under the Clean Water Act, regulates the discharge of pollutants from point sources into regional water resources. The NPDES permit regulates discharges of wastes for the purpose of limiting the quantity of pollutants and volume of waste discharged to surface waters.

NPDES permits contain prerequisite conditions that must be met by dischargers to ensure protection of the receiving water. Any agency or private party proposing to discharge pollutants into surface waters must submit a report of waste discharge at least 180 days in advance of the planned date of release. Concurrence with pollution elimination levels and approval of the report of waste discharge would culminate in the granting of an NPDES permit. Responsibility of enforcement of NPDES guidelines and permits falls within jurisdiction of the RWQCB (Region 8 for the San Jacinto Basin), and is subject to review by the Environmental Protection

Agency (EPA) Regional Administrator (EPA Region IX, San Francisco Office) (State of California 1995, p. 5-2).

The EPA has published NPDES permit application requirements for municipal, industrial, and construction stormwater discharges under the urban runoff management strategy. The application requirements for municipalities were directed at municipalities that own and operate separate storm drain systems servicing populations of 100,000 or more or that contribute significant pollutants to waters of the United States and require such agencies to obtain coverage under municipal stormwater NPDES permits. Municipalities were required to develop and implement an urban runoff management program to address activities to reduce pollutants in urban runoff and stormwater discharges that were contributing a substantial pollutant load to their systems.

In order to control water quality, the State Water Resources Control Board has organized basin plans for all drainage systems within California. Goals and plans set forth in the Water Quality Control Plan for the Santa Ana River Basin (State of California 1995) are carried out through the use of the NPDES permitting and monitoring system.
303(d) Status Listing
Under Section 303(d) of the 1972 Clean Water Act, states, territories, and authorized tribes are required to develop a list of water quality limited segments. These waters on the list do not meet water quality standards, even after point sources of pollution have installed the minimum required levels of pollution control technology. The law requires that these jurisdictions establish priority rankings for water on the lists and develop action plans, called Total Maximum Daily Loads (TMDL), to improve water quality.

California Water Code
The California Water Code is the principal policy that governs the use of water resources within the State of California. This code controls water rights, policies governing the construction and management of dams and reservoirs, flood control, conservation, development and utilization of state water resources, water quality protection, and management and management of wateroriented agencies (State of California 1995, pp. 1-1 to 1-2). The water quality provisions set forth in the California Water Code have been written to supplement certain provisions of the California Health and Safety Code, Public Resources Code, Fish and Game Code, Food and Agriculture Code, Government Code, Harbors and Navigation Code, California Environmental Quality Act, and the California Endangered Species Act.

Porter-Cologne Water Quality Control Act
Division 7 of the California Water Code, commonly referred to as the Porter-Cologne Water Quality Control Act, is the principal mechanism for water quality control within California. This act establishes a regulatory program to protect water quality and beneficial uses of all state waters. The Porter-Cologne Act established the State Water Resources Control Board and RWQCB as principal state agencies responsible for water quality control. Water quality of the Santa Ana River Basin is controlled by Region 8 Regional Water Quality Control Board of the State Water Resources Control Board (State of California 1995, p. 1-1).

Relevant Plans and Policies
Water Quality Control Plan for the Santa Ana River Basin (Region 8) The federal Clean Water Act, and, specifically the NPDES program as well as the California Water Code (specifically, the Porter-Cologne Water Quality Control Act) require that the Regional Water Quality Control Board adopt a water quality control plan to guide and coordinate the management of water quality in the Region. The Santa Ana River Basin Plan's purpose is to (1) designate beneficial uses of the Region's surface water and groundwater, (2) designate water quality objectives for the reasonable protection of those uses, and (3) establish an implementation plan to achieve the objectives. This basin plan was adopted in 1995 and has been subject to several amendments over the last 10 years. This plan outlines water quality planning guidelines for the Upper and Lower Santa Ana Region watersheds, the San Jacinto River watershed and several other small drainage areas in southwestern San Bernardino County, western Riverside County, and northwestern Orange County (State of California, Santa Ana RWQCB 1995).

The Villages of San Jacinto project is located approximately 1 mile southwest of the San Jacinto River. The Santa Ana River Basin Plan divides the County into "Hydrologic Units" (HU). Each HU has a "Hydrologic Area" (HA). Each HA can be divided into "Hydrologic Sub Areas" (HSAs). The project is located within the San Jacinto River Basin HU and the San Jacinto River HA. The project is located near Reach 4 - Nuevo Road to North–South Mid-Section Line (T4S/R1W-S8). Beneficial uses have been identified for each of the water bodies the project could potentially impact (State of California 1995, p. 3-21).

Inland Surface Waters
San Jacinto River HA: Beneficial uses include Municipal and intermittent beneficial uses include Agricultural, Groundwater, Recreation (1), Recreation (2), Warm Freshwater Habitat and Wildlife Habitat (State of California 1995, p. 3-21).

5.8 WATER QUALITY AND HYDROLOGY

The Basin Plan identifies Water Quality Objectives for each water body within the Santa Ana River Watershed. The project is located within an inland surface stream area, specifically Reach 4 of the San Jacinto River. Guidelines pertain to algae, un-ionized ammonia, acute (1-hour) ammonia-nitrogen, fecal coliform bacteria, boron, chemical oxygen demand, chloride, residual chlorine, color, total filterable dissolved solids, floatables, fluoride, hardness, inorganic nitrogen, metals, methylene blue-activated substances, nitrate, total inorganic nitrogen, oil and grease, total dissolved oxygen, pH, radioactivity, sodium, suspended and settleable solids, sulfate, sulfides, surfactants, taste and odor, temperature, toxic substances, and turbidity. The Basin Plan mandates that all waters of the region shall be maintained in accordance with each pollutant-specific objective and shall not be exceeded as a result of controllable water quality factors (State of California 1995, p. 4-34)
Groundwater
San Jacinto-Upper Pressure and Hemet-South: Beneficial uses include Municipal, Agricultural, Industrial, and Industrial Process Supply (State of California 1995, p. 3-27 and Figure 3-4).

The Basin Plan identifies Water Quality Objectives for each groundwater body within the Santa Ana River Watershed. The project is located within a groundwater area, specifically the San Jacinto – Upper Pressure basin. The Basin Plan quantifies limits or designates guidelines for discharge into the San Jacinto River. Guidelines pertain to arsenic, fecal coliform bacteria, boron, barium, chloride, color, cyanide, total dissolved solids, fluoride, hardness, metals, methylene blue-activated bustances, nitrate, oil and grease, pH, radioactivity, sodium, sulfate, taste and odor, total inorganic nitrogen, and toxic substances. The Basin Plan mandates that all waters of the region shall be maintained in accordance with each pollutant-specific objective and shall not be exceeded as a result of controllable water quality factors (State of California 1995, pp. 4-11 to 4-13, 4-34).

Lake Elsinore and Canyon Lake Nutrient TMDL Allocation and Implementation Plan According to the California 2002 303(d) list (approved by the USEPA on July 2003) published by the Santa Ana RWQCB, the San Jacinto River is not listed as an impaired water body. That said, Lake Elsinore, which is located downstream of the project site and is fed by the San Jacinto River, is listed on the 303(d) list as an impaired water body. The pollutants of concern in Lake Elsinore include nutrients, organic enrichment/low dissolved oxygen, sedimentation/siltation, and other pollutants where toxicity is unknown. Watershed-wide waste discharge requirements for discharges of stormwater runoff associated with new developments have been adopted for the San Jacinto River Watershed. These discharge objectives include the following:

Villages of San Jacinto EIR 4307-01

NPDES Stormwater Discharge Construction Permit (Water Quality Order 99-08-DWQ) Section 402 of the Clean Water Act establishes a framework for regulating municipal and industrial stormwater discharges under the NPDES program. This permit regulates stormwater runoff from construction sites where clearing; grading; or disturbances to the ground, such as stockpiling or excavation that results in soil disturbances of at least 1 acre of total land area, occurs.

5.8.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on water resources and water quality if it:

1. Violates any water quality standards or waste discharge requirements.

2. Substantially depletes groundwater supplies or interferes substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level that would not support existing land uses or planned uses for which permits have been granted).

3. Substantially alters the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would result in substantial erosion or siltation on- or off-site.

4. Creates or contributes runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources or polluted runoff.

5. Places housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map.

6. Place within a 100-year flood hazard area structures which would impede or redirect flows.

7. Exposes people or structures to a significant risk of loss, injury, or death involving flooding, including flooding as a result of the failure of a levee or dam.

8. Otherwise substantially degrades water quality.

5.8.4 Impacts
Would the project violate any water quality standards or waste discharge requirements? Perched groundwater was encountered at multiple depths below the surface, as shallow as 5 feet and as deep as 22 feet. Regional groundwater is anticipated below 150 feet and is likely to occur

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-11
as much as 200 feet below grade. However, groundwater can be expected to fluctuate seasonally within the subject site and during periods of heavy regional rainfall or groundwater withdrawal by the local residences, agricultural developments, and water utility companies. During drought conditions, groundwater levels could temporarily deepen significantly.

The project would not impact regional groundwater (Leighton 2006). All lake and drainage features on site would be constructed so they are above the regional groundwater table so as to prevent intermixing of ground and surface waters. That said, it is possible that, during project construction, perched groundwater may be encountered. In order to avoid potential impacts to regional groundwater resources in the San Jacinto River Valley, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-b).

Construction Impacts
Development of the proposed project may result in an increase in pollutant load due to sedimentation. Sediments are soils or other surficial materials eroded and then transported or deposited by the action of wind, water, or gravity. Sediment from erosion, primarily during construction, is quite often a major project pollutant of concern. A potentially significant impact could occur during construction related to sedimentation; therefore, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measures 5.8-d and 5.8-e).

As indicated above, groundwater may be encountered during construction. In order to prevent impacts to groundwater resources, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-b).

Operational Impacts
Based upon guidelines within the Riverside County Flood Control & Water Conservation District (RCFC&WCD) BMP Handbook and the Santa Ana RWQCB General Permit for Riverside County, the proposed development must treat potential contaminants produced and associated with the proposed land use types within the project site. As a result, a water quality extended detention basin is being proposed to provide water quality treatment for the runoff emanating from the project site. The volume calculations for the water quality basins are based upon the method included in the RCFC&WCD BMP Handbook. A water quality/extended detention basin is a permanent basin sized to detain and slowly release the design volume of stormwater, allowing particles and associated pollutants to settle out. An inlet forebay section and inlet energy dissipater will minimize erosion from entering flows, while erosion protection at the outlet prevents damage from existing flows. The bottom of the basin slopes toward the outlet and a low flow channel conveys incidental flows directly to the outlet end of the basin. The basin should utilize vegetated earth in order to allow some infiltration to occur, although highly pervious soils may require an impermeable liner to prevent groundwater contamination. Proper

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-12
turf management is also required to ensure that the vegetation does not contribute to water pollution through pesticides, herbicides, or fertilizers. The City of San Jacinto will maintain all aspects of the basin pertaining to water quality. RCFC&WCD will maintain all aspects of the basin that pertain to detention.

Lake Preliminary Design Report
This report (Pacific Aquascape, Inc. 2009) discusses safety features for the proposed lake shoreline, water depth and temperature, and treatment of runoff and water quality management.

The treatment process involves reduced concentration of dissolved pollutants, nutrients, and salts through flushing of the lake water volume by utilizing the lake as the irrigation supply source; reduction of nutrient concentrations from inflows, nitrogen, and phosphorous; prevention of algae blooms by using constructed gravel biofilter beds that utilizes "biological filtration"; and maintaining oxygen levels through aeration promoting oxygen exchange to prevent anaerobic conditions, which allows natural process to occur, such as denitrification for removal of nitrogen.

The lake operation and maintenance program also includes routine debris removal, algae control, aquatic weed control, pump maintenance, and biofilter maintenance. These processes ensure continued aesthetic appeal and desirable water quality as well as control of vectors, such as mosquitoes and flies
Agricultural Operations
The current and previous land uses on the project site generate nitrogen and phosphorous, which may have an impact on existing on-site and off-site water quality. Due to the elimination of agriculture, the project site will likely result in a beneficial impact due to a reduction in nitrogen and phosphorous.

Pollutants of Concern
Due to the intensification of land uses on the site, in combination with an increase in impervious surfaces, the project may result in potentially significant impacts to water quality attributable to urban pollutants contained in stormwater runoff. The constituents described below commonly are found on similar developments as a result of urban runoff and could, therefore, affect the proposed project's water quality. The development of a final Water Quality Management Plan (WQMP) as specified in Mitigation Measure 5.8-f, ensures that overall reduction is achieved for all pollutants listed below. An extended detention basin and vegetated swale (vegetated channel) as proposed, has low to high removal effectiveness for all pollutants per the Riverside County Stormwater Quality BMP Design Handbook (RCFC&WCD, July 21, 2006). Other project specific measures are proposed which will ensure that the project will not violate any water quality standards or waste discharge requirements.

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-13
Nutrients
Nutrients are inorganic substances, such as nitrogen and phosphorus. The primary sources of nutrients in urban runoff are fertilizers and eroded soils. Due principally to the type of land use, the project is anticipated to result in the transport of fertilizers from landscape areas by stormwater or water from irrigated sprinklers and wash down activities, resulting in a potentially significant impact. In order to reduce this potential impact, mitigation is provided (see Section

5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Heavy Metals
metals are raw material components in non-metal products, such as fuels, adhesives, paints, and other coatings. Under the proposed project, it is anticipated that heavy metals from vehicles on parking lots and streets may be transported to the storm drain system, resulting in a potentially significant impact (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Organic Compounds
Commercially available or naturally occurring carbon-based organic compounds are found in pesticides, solvents, and hydrocarbons. Landscaping associated with the proposed project may result in release of organic compounds, therefore mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Trash and Debris
The introduction of a suburban population to the area will contribute to an increase in trash and debris pollution, which will result in a potentially significant impact. In order to reduce potentially significant impacts, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Oxygen-Demanding Substances
Biodegradable organic materials on site could react with dissolved oxygen in the water to form other compounds. It is anticipated that an increase in population in the area would result in a likely increase of oxygen-demanding substances in urban runoff, therefore creating a significant impact. In order to reduce this potential impact, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Oil and Grease
Oil and grease are characterized as high-molecular-weight organic compounds. The primary source of oil and grease of concern to the proposed project would be leaky cars. Because of their

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-14
respective increase in parking facilities, it is anticipated that the mixed-use, commercial, school, and public park uses would result in potentially significant impacts related to oil and grease. In order to reduce this potential impact, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Bacteria and Viruses
Pathogens such as bacteria and viruses are typically caused by the transport of animal or human fecal wastes from the watershed primarily through improper or non-disposal of pet wastes.

Water, containing excessive bacteria and viruses can alter the aquatic habitat and create a harmful environment for humans and aquatic life. Also, the decomposition of excess organic waste causes increased growth of undesirable organisms in the water. In order to compensate for this potentially significant impact, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Pesticides
Herbicides used for controlling nuisance plant growth are a potential source of pollutants.

Because the project will introduce new landscaping to the project site, the introduction of herbicides into stormwater runoff is considered a potentially significant impact. In order to reduce this potentially significant impact, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-f).

Would the project substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level that would not support existing land uses or planned uses for which permits have been granted)?
The Water Supply Assessment Report prepared for the project (Appendix K) indicates that the total projected water demand for the proposed development would remain within the limits of the projected demand of the Eastern Municipal Water District’s Urban Water Management Plan 2000 (refer to Section 5.12.8 for a detailed discussion of domestic water supply).

The project would result in an increase in impervious surfaces due to the change from an existing agricultural operation (which supports natural percolation) to that of a suburban housing/commercial/retail development (which will support pavement and other impervious surfaces). Although the project would not result in the exact same local groundwater recharge characteristics, the project drainage plan would facilitate complete retention/detention of water onsite to mirror pre-development flows. Therefore, during weather events, water will be directed to the urban drainage system which will collect at the northwest of the site in a detention basin.

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-15
This basin will result in the percolation or evaporation of all onsite water which would in effect help mirror existing, pre-development groundwater recharge.

Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would result in substantial erosion or siltation on- or off-site?
A Drainage Plan has been incorporated into the Specific Plan for the project and is based on the findings in the February 2009 JLC Engineering Hydrology Study referenced above. Proposed drainage facilities are shown on Figure 5.8-2, On-Site Drainage Plan. The project site generally drains in a northwesterly direction toward the San Jacinto River, primarily in a sheet flow pattern. The northerly portion of the project site is within the 100-year floodplain. The Drainage Plan provides 100-year flood protection for the project site for the interim and ultimate conditions as described below.

Interim Condition
The interim condition assumes that the off-site area is undeveloped in the existing condition, and the on-site development of the Villages of San Jacinto and corresponding infrastructure is functional. These interim drainage facilities would be developed concurrently with phase I, and are required to control and convey the interim flow rates originating from the off-site area.

Interim condition calculations were used to determine the points where flows enter the site and to size the corresponding facilities. Following is a summary of the interim drainage facilities:
• Culvert V, shown on Figure 5.8-2, is a proposed culvert south of the Bridge Street and Cawston Avenue intersection that will collect the runoff that overtops the Casa Loma Canal Siphon. The proposed culvert will discharge the runoff into the Line V Channel.

The culvert will provide 100-year flood protection for Bridge Street. The ultimate flow rate will substantially decrease once the San Jacinto Master Drainage Plan (MDP) facilities Line D and Casa Loma Basin are constructed.
• Culvert E shown on Figure 5.8-2 is a proposed culvert located north of the intersection of Sanderson Avenue and the Casa Loma Canal. Based on the current topography, the runoff emanating from the east side of Sanderson Avenue will overtop Sanderson Avenue and enter the project site. As a result, a culvert and earthen channel system have been proposed at the southeast corner of PA 11. These facilities will convey the 100-year flow rate to the Line E system. The San Jacinto MDP proposes drainage system Line E2 will ultimately collect the flows emanating east of Sanderson Avenue. • The earthen roadway on the land east of Sanderson Avenue, north and south of the intersection of DeAnza Drive and Sanderson Avenue, is not a permitted structure and diverts substantial runoff to the project site, indicated as Off-site Flow 3 on Figure 5.8-2.

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01
August 2009 5.8-16
This diversion occurs because the height of the earthen roadway produces a ponding condition south of the earthen roadway, which forces flows to overtop Sanderson Avenue. The roadway will be reconstructed and lowered to an elevation that will eliminate the ponding condition and allow flows to overtop this roadway, thereby eliminating the overtopping condition on Sanderson Avenue.

Ultimate Condition
The ultimate condition assumes that the San Jacinto MDP systems are in place and functional.

With these facilities in place, the off-site area that is tributary to the Villages of San Jacinto is reduced to the area between the Casa Loma Canal and Bridge Street.

Figure 5.8-2 provides the locations where the existing off-site runoff enters the project site (1, 2, and 3) and the corresponding 100-year peak flow rate for the interim condition. However, the runoff entering the project site will eventually be eliminated with the implementation of the San Jacinto MDP.

The implementation of the San Jacinto MDP is based on the timing of the development of the surrounding area. As a result, the construction timeline for the proposed San Jacinto MDP drainage facilities is unknown. Consequently, the project incorporates a drainage plan that will not impact upstream and downstream property owners but will provide flood protection for the overall project site. The drainage plan will incorporate a vegetative channel and a detention/water quality basin, which are designated as Line V and Detention Basin V. These two facilities are the major backbone infrastructure that will collect the runoff that emanates from off-site and on-site areas. Line V and Detention Basin V have been designed to convey and control the interim flow rate and ultimate flow rate. As discussed previously, the interim flow rate results in a runoff rate that exceeds the ultimate condition flow rate. The Line V Channel will allow for the connection of several storm drain laterals. The limits of the storm drain laterals are based on the street design policy implemented by the City of San Jacinto and the County of Riverside. These storm drain laterals will provide 100-year flood protection for the on-site planning areas and ensure that downstream properties would not be impacted by increased flows released from the project site.

Because the San Jacinto MDP facilities would be designed to handle the increase in drainage from the project site once developed, impacts to surface water would not be significant.

However, in accordance with San Jacinto requirements, the project shall be required to participate in the San Jacinto River levee financing project (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-a).

Would the project create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources or polluted runoff?
As discussed above, the project incorporates a drainage plan that will not impact upstream and downstream property owners but will provide flood protection for the overall project site.

Implementation of the San Jacinto MDP is based on the timing of the development of the surrounding area and will further improve drainage systems in the project area.

Would the project place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map?
The northern portion of the project site is located within Zone A (100-year floodplain as mapped by FEMA) of the San Jacinto River. Development within the floodplain may result in an impedence to flow and an increase in the base flood elevation. Because a portion of the proposed development is proposed to be constructed within the limits of the 100-year floodplain, development of the proposed project will result in potentially significant impacts relating to flood hazards. As discussed above, the project drainage plan will provide 100-year flood protection for the project site and will not adversely affect downstream properties. However, mitigation is required to have the project removed from the appropriate FEMA floodplain map.

In order to avoid impacts, mitigation is provided (see Section 5.8.5, Mitigation Measures, Mitigation Measure 5.8-c).

It should be noted that the project site elevation will be raised during grading activities to ensure that future structures are outside of the 100-year floodplain.

Would the project place within a 100-year flood hazard area structures which would impede or redirect flows?
As discussed in preceding responses, the project drainage plan will ensure that adequate flood protection is provided and the placement of new structures would not impede or redirect 100- year flows or result in on-site or off-site flooding as a result of project implementation.

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01

Would the project expose people or structures to a significant risk of loss, injury, or death involving flooding, including flooding as a result of the failure of a levee or dam? The project would not expose people or structures to a significant flood risk as discussed in the preceding responses. Adequate flood protection will be provided in the absence of the planned San Jacinto River levee project, which will provide additional protection from flooding in the project area.

Would the project otherwise substantially degrade water quality? The project would not have a significant impact on water quality as discussed in detail in the first impact response above.

5.8.5 Mitigation Measures

5.8-a The project is located within the San Jacinto – Area Drainage Plan (SJ-ADP), which is a financing mechanism used to offset costs for construction of proposed Master Drainage Plan (MDP) facilities. The project will be charged a per-acre fee in order to pay a fair share of the price of area-wide drainage facilities.

5.8-b If dewatering becomes necessary during construction, all discharges shall be in accordance with Santa Ana Regional Water Quality Control Board requirements which mandate that dewatered groundwater be tanked and hauled to a legal disposal site for treatment. Dewatering shall not occur in on-site drainages or water features. In addition, if dewatering becomes necessary during construction, a National Pollution Discharge Elimination System dewatering permit shall be obtained from the Santa Ana Regional Water Quality Control Board.

5.8-c All buildings shall be located outside of the 100-year floodplain. The applicant shall process a Flood Insurance Rate Map (FIRM) map revision. Further, the applicant shall obtain a Conditional Letter of Map Revision (CLOMR) prior to issuance of building permits. The project applicant, or subsequent property owners, shall obtain flood insurance, to the extent required by law, to protect against any damage that might occur during a flood event. It must be noted that at the time of EIR publication, the applicant and City had initiated the CLOMR process with the Riverside County Flood Control and Water Conservation District.

5.8-d During construction, the project will incorporate all City of San Jacinto construction Best Management Practices (BMPs). These BMPs include the following:
• Erosion control BMPs, including temporary seeding and permanent seeding • Soil stabilization BMPs
• Sediment control BMPs, including silt fence perimeter controls, surface roughening, tree or natural vegetation preservation and protection, temporary gravel construction entrance/exit, temporary diversions, permanent diversions, outlet stabilization, inlet protection, temporary sediment basins, and gravel bay barriers. • Wind erosion BMPs
• Minimize contact with stormwater BMPs, including BMPs for construction vehicles and equipment maintenance, fueling, and washing; materials maintenance; and construction material loading, unloading, and access area controls. • Non-stormwater BMPs.

5.8-e The project applicant will need to develop a Stormwater Pollution Prevention Plan (SWPPP) pursuant to NPDES Stormwater Discharge Associated with Construction Activity Guidelines (Water Quality Order 99-08-DWQ). The SWPPP will identify all BMPs that will prevent construction pollutants from contacting stormwater. Measures shall also be designed so as to prevent all products of erosion from moving off site into receiving waters. Provisions will also be included to ensure that BMPs are monitored and success recorded.

5.8-f Structural BMPs are required for new development to improve water quality of stormwater runoff. In order to meet NPDES regulations, the design volume or design flow to be treated must reduce pollutants to the Maximum Extent Practicable (MEP).

This project will incorporate a water quality extended detention basin to provide water quality treatment for the runoff emanating from the project site, a volume-based BMP, and a flow-based BMP. Once the project is complete, maintenance will be the responsibility of the Villages of San Jacinto homeowners association.

In addition to sizing techniques, several quantity-control BMPs shall be implemented to control runoff:
• Rainfall shutoff devices shall be used to prevent irrigation during and after precipitation
• Irrigation systems shall utilize a dripping system to eliminate nuisance runoff • Backflow preventer/pressure regulators shall be installed.

5.8 WATER QUALITY AND HYDROLOGY
Villages of San Jacinto EIR 4307-01

The project applicant will need to develop a Water Quality Management Plan pursuant to NPDES Permit No. CAS 618033, order No. R8-2002-001. The Water Quality Management Plan will identify all final site BMP requirements.

The following BMPs may be incorporated into final site designs:
• Construct community streets, sidewalks, and parking lot aisles to the minimum widths necessary
• Incorporate landscape treatment for parking lot runoff • Use unit pavers or other equivalent porous material to construct walkways, alleys, and other low-traffic areas
• Utilize trees in landscaping plans to maximize canopy interception and water conservation
• Plant native trees and maximize canopy interception and water conservation • Drain rooftops into adjacent landscaping prior to discharging to the storm drain • Vegetate slopes with native or drought tolerant vegetation • Install energy dissipaters at the outlets of new storm drains that enter the regional storm drain system that eventually feeds into the San Jacinto River. • Utilize and install “high to medium efficiency” Post Construction BMP filtration system within the proposed water quality basin that would help reduce as many bacteria and viruses as possible from entering the downstream local stormwater collection system. This system must follow the specifications of the California Stormwater Handbook to ensure that the system provides maximum bacteria/viral capture.

5.8.6 Residual Impacts/Level of Significance after Mitigation After application of the proposed mitigation measures, any potentially significant impacts relating to hydrology, groundwater, or water quality that are attributable to the development and operation of the proposed project would be reduced to a level below significant. Therefore, no significant unavoidable impacts are expected.

This latest report is an update of the May 23, 2005, Traffic Impact Analysis prepared by Urban Crossroads for the April 2006 DEIR. The original report was revised to reflect changes in project land uses, revised phasing plan, and revisions to the Mid-County Parkway southerly alignment within the project study area.

The traffic study analyzes the potential impacts of cumulative conditions representing the phased occupancy timing of the project, including Phase I, year 2015; Phase II, Year 2017; Phase III, Year 2023; and General Plan build-out conditions in Year 2035. The traffic impact analysis documents existing traffic conditions in the vicinity of the project site, Existing Plus Ambient Plus Project conditions for Phase I, Phase II and Phase III conditions; Existing Plus Ambient Plus Cumulative conditions (EAC 2015); Existing Plus Ambient Plus Cumulative plus Phase I conditions (EACP 2015); Existing Plus Ambient Plus Cumulative conditions (EAC 2017); Existing Plus Ambient Plus Cumulative Plus Phase I and Phase II conditions (EACP 2017); Existing Plus Ambient Plus Cumulative conditions (EAC 2023); Existing Plus Ambient Plus Cumulative Plus Phases I through III conditions (EACP 2023); evaluation of General Plan buildout (2035) with project conditions; and identifies on-site and off-site improvements and system management actions to achieve adequate level of service requirements as required by the City of San Jacinto.

The traffic analysis utilizes information obtained from City of San Jacinto staff to define the study area intersections and identify other development and area-wide growth calculations used in traffic counts. Due to the project's size and phased implementation plan, the traffic analysis was reflective of the phasing plan. Because the mitigation measures will be implemented as the project is constructed and traffic improvements become necessary, the phasing plan is reflected in the on-site mitigation measures. The City of San Jacinto and Riverside County General Plan Circulation Elements were used to identify the regional and City street network and roadway cross-sections in the study area. The traffic study has been prepared in conformance with the goals and requirements of the San Jacinto General Plan Circulation Element. Traffic operations and level of service conditions were evaluated pursuant to the 2000 Highway Capacity Manual (HCM).

As indicated in Section 3.0, Project Description, the proposed project would result in 1,016 low to medium density single-family dwelling units, a 2,000 student-high school, 247,000 square feet

of neighborhood retail commercial uses, 343,000 square feet of mixed-use development and approximately 43 acres of park land. However, in the event that the high school is not built, an additional 313 single-family housing units would be constructed, which would result in the potential for 1,329 units to be developed on site. While on the surface it may seem that the 1,329 unit count scenario would result in more traffic, traffic analyses are based on peak hour measurements, which for this project, would be more trip-intensive in the school scenario.

Therefore, this traffic analysis reflects the 1,016 unit project with high school scenario, in order to provide the public with a "worst case scenario."

5.9.2 Existing Conditions
The project site is generally located south of Ramona Expressway and directly west of North Sanderson Avenue in the City of San Jacinto. North Sanderson Avenue is identified as an urban arterial roadway in the City of San Jacinto General Plan Circulation Element. Figure 5.9-1, Existing Lane and Intersection Conditions, illustrates the primary roadway components of the study area street network and identifies the number of traffic lanes for each roadway and existing intersection traffic controls.

Intersection Conditions
Traffic flow on arterial streets is most constrained at intersections; therefore, the traffic analysis focuses on the operating conditions of critical intersections during peak travel periods. The traffic report utilized information obtained from City of San Jacinto Transportation staff to identify the key intersections within the study area for analysis. The following intersections were analyzed in this study:
• Rider Street (NS) at:
o Ramona Expressway (EW)
• Lakeview Avenue (NS) at:
o Ramona Expressway (EW)
• Bridge Street (NS) at:
o Ramona Expressway (EW)
• Warren Road (NS) at:
o Ramona Expressway (EW)
o Cottonwood Avenue (EW)
o Esplanade Avenue (EW)

o Gilman Springs Road NB Ramps (EW)
o Ramona Expressway (EW)
o Ramona Boulevard North (EW)
o Cottonwood Avenue (EW)
o Esplanade Avenue (EW)
o Florida Avenue (SR-74) (EW)
• State Street (NS) at:
o Ramona Expressway (EW)
o Cottonwood Avenue (EW)
o Esplanade Avenue (EW).

The existing conditions of each intersection listed above are characterized by Average Daily Trip (ADT) volumes and Level of Service (LOS) ratings. Figure 5.9-2, Existing Traffic Volumes, illustrates existing ADT volumes on arterial streets in the study area. Figure 5.9-3, Existing AM Peak Hour Intersection Volumes, and Figure 5.9-4, Existing PM Peak Hour Intersection Volumes, depict the distribution of existing ADT volumes on the study area roadway system.

Existing ADT volumes are based on direct machine counts or factored from peak hour counts conducted for Urban Crossroads, Inc. in conjunction with the project traffic study.

In evaluating the existing intersection conditions, a "Level of Service (LOS)" rating, which consists of A through F, is used. LOS A indicates excellent conditions of uninterrupted free-flow traffic operations and LOS F indicates poor conditions of interrupted flow and congested operations (gridlock). Complete definitions of LOS categories are included in the Traffic Impact Analysis, included in Appendix H to this EIR. Different factors are considered in determining LOS for each intersection and are dependent on the type of intersection control used (i.e., signal, street stop, etc.). For signalized intersections, average total delay per vehicle for the overall intersection is used to determine level of service. For stop sign–controlled intersections, the calculation of LOS is dependent on the occurrence of gaps occurring in the traffic flow of the main street. For all way stop controlled intersections, the LOS criteria for this type of intersection analysis are also based on average total delay per vehicle for the overall intersection.

The traffic analysis considers LOS D to be the minimum acceptable operating condition for intersections consistent with the adopted standards of the City of San Jacinto.

For the project area, traffic demands are highest at key intersections during the A.M. and P.M. peak hour periods. Table 5.9-1, Existing Intersection Conditions summarizes the results of evaluating existing peak hour traffic operations for intersections in the study area, and includes information relative to each intersection's geometrics, traffic control device and existing LOS.

Alternative Transportation
Public bus service in the project vicinity is provided by the Riverside Transit Agency. Three bus routes operate within the City of San Jacinto. However, there are currently no transit facilities or designated bikeways operating in the study area.

Regulatory Framework
The Western Riverside Council of Governments (WRCOG) is a council which is comprised of members representing 15 local jurisdictions in western Riverside County, including the City of San Jacinto. The WRCOG functions to facilitate collective assessment of regional issues, such as traffic, by the various representative jurisdictions. In June 2004 WRCOG adopted the

5.9 TRANSPORTATION, CIRCULATION, AND ACCESS
Villages of San Jacinto EIR 4307-01
August 2009 5.9-14
Transportation Uniform Mitigation Fee (TUMF) 10-Year Strategic Plan and Transportation Improvement Program Development Guidelines.

The purpose of the TUMF program is to establish a comprehensive funding source for infrastructure improvements to mitigate cumulative regional transportation impacts of new development on regional arterial highways (Parsons Brinckerhoff Quade & Douglas, Inc., June 2004). The TUMF program has 5 primary goals that are articulated as a basis for developing specific project priorities and selection criteria. These goals are summarized as follows:
• Sustain Mobility – Mitigate the transportation system impacts of new development • System Continuity – Enhance the continuity of the regional arterial highway system • Project Development – Encourage systematic project development and provide flexibility to advance TUMF projects promptly through completion
• Leverage Funds – Secure additional matching funds for TUMF system improvements • Regional Benefit – Ensure TUMF program revenues are distributed to maximize mitigation of new development impacts.

The TUMF program is intended to address cumulative traffic impacts of new development to the region and therefore TUMF program funded improvements are focused primarily on regional arterial highways. New development in Western Riverside County places additional demand on the regional transportation system to provide safe and convenient access for new residents and employees. The additional demand on the transportation facilities reduces mobility absent adequately and timely funded infrastructure improvements implemented to meet growing demands. As such, WRCOG has developed and implemented the TUMF program which requires new development to contribute revenues to partially fund improvements that will mitigate the transportation impacts of new developments. TUMF investments are then focused on those regional facilities most impacted by new development. The TUMF program assigns impact fees on a per dwelling unit basis for residential development and a per square foot basis for nonresidential uses (i.e., commercial, industrial, office).

The City of San Jacinto also implements a Development Impact Fee (DIF) which consists of a "Streets and Roads" component and a "Traffic Signals" Component. The DIF program assigns impact fees on a "per acre" basis for non-residential development and a per unit basis for residential development. Fee calculations for both the TUMF and DIF programs are shown in Section 5.9.5.

5.9.3 Significance Criteria
Based on the criteria identified in Appendix G of the CEQA Guidelines, the proposed project would have a significant impact on transportation, circulation and access if it:

1. Would cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)

2. Would exceed, either individually or cumulatively, a level of service standard established by the County Congestion Management Agency for designated roads or highways

3. Would result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks

4. Would substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)

5. Would result in inadequate emergency access

6. Would result in inadequate parking capacity

7. Would conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks).

5.9.4 Impacts
Would the project cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? Would the project exceed, either individually or cumulatively, a level of service standard established by the County Congestion Management Agency for designated roads or highways? Project Traffic
In order to characterize potential traffic impacts associated with the project, a characterization of the project's contribution to local traffic levels must occur. Site traffic is characterized by trip generation, trip distribution, modal split, and trip assignment.

As indicated in Section 5.9.1, the proposed project's "worst case" traffic impact scenario would be a land use scenario that includes construction of the planned high school, in effect a 1,016-unit development. Trip generation rates are based upon the proposed land use plan and data collected by the Institute of Traffic Engineers (ITE), Trip Generation Manual, 7th Edition.

Trip generation rates for each proposed land use are shown in Table 5.9-2, Project Trip

Trip Generation Summary
Due to the size and diversity of land uses of the proposed project a certain portion of the anticipated ADT will simply circulate internally rather than exit the development to travel to other destinations. This factor, deemed "internal capture," would include vehicle trips from the residential areas to school, residential areas to shopping center and residential areas to the mixeduse area. The number of internal capture trips was calculated for each building phase of the project. As shown in Table 5.9-3, the project is estimated to generate a total of 27,166 net external ADT for all four phases after accounting for internal trips and "pass-by" trips (i.e., traffic that will access the site on the way to another primary destination).

Trip distribution represents the directional orientation of traffic to and from the project site. Trip distribution is heavily influenced by the geographical location of the site, the location of employment, commercial and recreational opportunities and the proximity to the regional freeway system. Trip distribution for this project is based upon near-term conditions which include those roadway facilities which are either in place or are expected to be in place over the next several years. Roadway construction and improvements that are assumed to be in place in conjunction with each phase of the project are detailed in Section 4.2 of the Traffic Impact Analysis in Appendix H.

Due to the lack of anticipated public transit facilities within this portion of the City of San Jacinto, the traffic-reducing impact of public transportation facilities has not been considered for this project. Should transit facilities become a part of this area, they would in effect reduce traffic levels and reduce anticipated impacts described herein.

The assignment of traffic from the site to the adjoining roadway system has been based upon the site's trip generation, trip distribution, proposed arterial highway system and local street systems.

Project generated traffic is then combined with background traffic and projected future traffic to estimate impacts on the study area roadways as described below.

Cumulative Traffic
In order to fully address traffic impacts, an impact analysis assuming the ultimate build out of other planned projects (cumulative projects), must be performed. These projects were based on information provided by the City of San Jacinto and County of Riverside and include projects that are under construction or are under review in the project area.

Several cumulative projects were identified for this analysis and have been divided into 28 traffic analysis zones (TAZ). Table 5.9-4, 2023 Cumulative Project Trip Generation, provides a summary of the total anticipated units (if residential) or square footage (if commercial) and daily AM and PM peak hour trips assumed in each TAZ based on known project information. Daily and peak hour trips that would be generated by the additional development proposals in the study area were calculated and the projected generated traffic was distributed and assigned to the study area street system.

In addition to project-generated traffic and anticipated traffic generation from additional approved or pending development in the study area, area wide growth (ambient growth) has been considered in the traffic analysis. Based on information obtained by City staff, future traffic volumes have been calculated by using an anticipated 3% annual growth rate for the years 2008–2015 and a 1% growth rate for the years 2015–2023, which has been added to project-related and other development-related daily and peak hour traffic volumes (see Exhibit 4-K through 4-T in Appendix H for graphical depictions of each cumulative project's location and anticipated trip distribution).

Intersection Impacts for Existing Plus Ambient Plus Project Conditions In order to identify direct project impacts, interim year analyses were performed for three Existing Plus Ambient Plus Project (EAP) scenarios. These scenarios don't include the cumulative projects that were identified above, but do include ambient traffic growth rates for each study year which corresponds to the project phasing. The following three sets of traffic volume conditions have been forecasted:
• 2015 EAP with Project Phase I
• 2017 EAP with Project Phases I + II
• 2023 EAP with Project Phases I + II + III.

The intersection levels of service for each of the scenarios are shown in Table 5.9-5 through Table 5.9-7. Those intersections shown as "Does Not Exist" would not have been built at the timing for the scenario being analyzed. The intersection turning movement volumes for each scenario are shown on Exhibits 5-A through 5-F in Appendix H.

Intersection Analysis for Cumulative Conditions with Project In order to identify the improvements required to achieve acceptable levels of service for each Interim Year with cumulative development (as described in Table 5.9-4) with project conditions, the following EACP (existing + ambient + cumulative + project) traffic forecast scenarios have been provided:
• 2015 EACP with Project Phase I
• 2023EACP with Project Phases I + II
• 2023 EACP with Project Phases I + II + III.

For EACP 2015 traffic conditions, all of the study area intersections are projected to operate at unacceptable LOS E or F during the peak hours without improvements. As shown in Table 5.9-9, some of the improvements required to achieve acceptable LOS exceed the General Plan typical roadway cross sections and are therefore not feasible due to the uncertainty of obtaining adequate right-of-way for such measures. These instances include the triple left turn lanes required at Warren Road at Ramona Expressway, the extensive improvements required along Sanderson Avenue (which don't provide acceptable LOS for the PM peak hour), and the three through lanes along Esplanade Avenue. The improvements which go beyond General Plan standards are due to the lack of alternative routes which would be provided upon completion of the Mid-County Parkway and SR-79 improvements which are not included in the EACP 2015 analysis. In order to minimize required improvements, a further analysis was done which includes completion of the Mid-County Parkway and SR-79 improvements for those intersections affected by these projects. The analysis also included required improvements for General Plan build-out conditions. As shown on Table 5.9-10, the improvements in excess of the ultimate planned roadway cross-sections at the study intersections would not be required to achieve acceptable LOS for the EACP 2015 scenario (with completion of the Mid-County Parkway and SR-79 improvements). Further, insuring that adequate right-of-way exists would entail an amendment to the Circulation Element. Because such an amendment can't be accommodated for only a portion of the City, it would result in a Circulation Element amendment that is City-wide which is not appropriate. However, it should be noted that completion of these regional improvements can't be guaranteed by the City. As such, the project would contribute to a significant unmitigable impact for EACP 2015 traffic conditions if these improvements are not in place.

Construction Related Traffic Impacts
Construction-related traffic would involve approximately 20 to 40 workers per day at the project site during each construction phase. Construction-related traffic would use Sanderson Avenue as the primary north/south access to and from the project site while various east/west routes may be used as appropriate during each phase of the project. Mass grading for the entire site would start in December 2011 and would be completed 7 months after. The grading plans anticipate that cut and fill will be balanced; no export or import of soil is planned. Phase I would be completed in December 2015. Fine grading for Phase II would start immediately after the completion of Phase

I in January 2016. Phase II would be completed in December 2017. Phase III would commence immediately after the completion of Phase II in December 2017. Phase III would include the construction of single-family residences and a high school. In July 2018, six months into the development phase, construction of the high school would start. Phase III, including the high school, would be completed in December 2023. Construction of the remaining nonresidential land uses in Phase IV would start in January 2024 and would be completed by December 2033.

The project would involve multiple construction subphases: 1) mass grading, 2) fine site grading of individual phases, 3) utilities/infrastructure (trenching), 4) building construction, 5) paving, and 6) architectural coating. Phases I, II, III, and IV would involve separate construction subphases with the exception of mass grading, which will cover the entire project site and occur during Phase I only. The proposed project would commence in 2011 and would be completed by 2033, for a total construction duration of 22 years. Table 5.9-16 presents the heavy construction equipment assumptions for each construction stage.

The additional worker and construction-related truck trips to and from the project site would potentially affect traffic operations at project area intersections during peak hours. Potential constructed-related traffic impacts are considered adverse, but less than significant because the increased traffic generation during peak hours would be temporary and intermittent during the construction periods. However, in order to avoid hazards or short-term delay, mitigation is provided for short-term construction traffic impacts (see Section 5.9.5, Mitigation Measures, Mitigation Measure 5.9-f). This measure requires a traffic control plan for each phase of the project which will serve to eliminate any potential hazards to surrounding roadways due to abnormally high traffic into or out of the site for a concentrated period of time.

Would the project result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? The proposed residential and commercial/retail structures would not impede existing air traffic navigational patterns or cause a change in the location of existing airport facilities in the region.

Therefore, no impacts related to air traffic patterns would occur.

Would the project substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Site access for the proposed development would be provided via a total of 17 driveways including seven full access driveways taking access from Odell Avenue, Cawston Avenue, Sanderson Avenue, Ramona Boulevard South, Bridge Street and De Anza Drive. The location of all driveways and traffic signal installations are shown below on Figures 5.9-5 through 5.9-8.

The proposed project provides appropriate access points and interior circulation patterns to ensure that adequate access and circulation is provided to and throughout the development. Site distance at each project access point would be reviewed to ensure standard Caltrans and City of San Jacinto sight distance requirements are provided by the project to avoid potential dangerous intersections. In addition, stop sign, stop bar, and stop legends would be provided at all project

driveways that intersect with public roadways (those not meeting traffic signal warrants), and onsite traffic signing and striping would be implemented in conjunction with detailed construction plans for the project site to ensure that the project provides adequate and safe site access and circulation, which meets minimum design standards applicable to the proposed development.

Mitigation measures that address project-related and cumulative traffic volume impacts to the surrounding street network will ensure that site access from the adjacent street system is maintained at acceptable levels to ensure that adequate and safe access and circulation is provided to the site (see Section 5.9.5, Mitigation Measures, Mitigation Measures 5.9-a through 5.9-f).

Would the project result in inadequate emergency access? As discussed above, the project will provide a total of 17 driveways including seven full access driveways and provides interior circulation patterns to ensure that adequate access and circulation is provided to and throughout the development. Therefore, no significant impacts related to emergency access would occur.

Would the project result in inadequate parking capacity? The project is designed to have adequate parking for the proposed commercial, recreational and residential facilities. Parking requirements are set forth in the Villages of San Jacinto Specific Plan for each Planning Area within the development. Adherence to the project development standards will ensure that there is adequate parking for each proposed land use. The school facility, if built, is subject to the standards for parking adopted by the San Jacinto Unified School District.

Would the project conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)?
There is currently no bus routes located on or near the project site. Local transit service is provided by the Riverside Transit Agency (RTA) with the nearest route (Route 31) traveling north-south through the City on State Street approximately two miles east of the site. Bus stops and or turnouts could be provided in the future, should RTA decide to locate a route adjacent to the site. One of the goals of the project is to develop a circulation system that meets projected traffic volumes and accommodates a variety of transportation modes and encourages alternatives to automobile use within the community. Design features include a series of landscaped paseos that will serve as pedestrian linkages between land uses. Pedestrian friendly design is encouraged for the mixed use and commercial portions of the project as well. Therefore, the project will not conflict with any adopted policies supporting alternative transportation.
