3.11.3 Cumulative Population and Housing Impacts
Approved Project
Less Than Cumulatively Considerable Impact. EIR No. 331 analyzed potential cumulative impacts of the Approved Project in the context of growth projections for the City of Anaheim set forth in the adopted General Plan Update in September 2003. According to the certified General Plan Final EIR associated with the General Plan Update, a maximum of 2,500 units and an average household occupancy of 3.3 persons per unit were assumed within the Specific Plan Area. Because the Approved Project did not propose an increase in the allowable residential development within the Specific Plan Area, the Approved Project was found to be consistent with the MPSP’s planned population and housing parameters as set forth in the General Plan Final EIR. In addition, the employment-generating land use parameters of the Approved Project were found to be consistent with the parameters of the General Plan Final EIR. As such, cumulative analysis conclusions from the General Plan Final EIR, which concluded that impacts to population and housing would not be cumulatively considerable, were found to be applicable to the Approved Project. No significant adverse cumulative impacts to employment, housing, or population were identified in EIR No. 331.

Proposed Project
Less Than Cumulatively Considerable Impact. As with the Approved Project, the Proposed Project can be considered in the cumulative context of growth projections for the City of Anaheim.

However, according to the City’s April 2023 Draft General Plan Housing Element Update, the maximum permitted number of units within the Specific Plan Area remains 2,500. However, it should be noted that the city did not consider the 2,500 residential units previously approved within the Specific Plan Area as contributing to the City’s RHNA obligation due to the establishment of the 2014 conservation easement.

The Proposed Project would include the establishment of cemetery uses within DA 5 of the MPSP Area, in which EIR No. 331 analyzed a buildout of 1,595 residential units. Therefore, the Proposed Project does not include any residential uses with the potential to result in cumulatively considerable impacts to population and housing. Further, the Proposed Project would not hinder the City’s achievement of its RHNA allocation, since the 2,500 units within the MPSP were not considered as part of this allocation in the Sixth Cycle Housing Element.

Because the Approved Project was found to have less than cumulatively considerable impacts relating to population and housing and the Proposed Project would not propose any residential units or major employment centers, no significant adverse cumulative impacts to employment, housing, or population would occur under the Proposed Project.

3.11.4 Findings Related to Population and Housing

3.11.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR Based on the foregoing analysis and information, there is no evidence that the Proposed Project requires a major change to EIR No. 331. The Proposed Project would not result in new significant environmental impacts related to population and housing, and there would not be a substantial increase in the severity of impacts described in EIR No. 331. 3-139

3.11.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR No major changes to the Specific Plan Area have taken place since preparation of EIR No. 331 that would require revisions to the analysis in EIR No. 331. There is no information in the record or otherwise available that indicates that there are substantial changes in circumstances pertaining to population and housing that would require major changes to EIR No. 331.

3.11.4.3 No New Information Showing Greater Significant Effects than the Certified EIR This Addendum has analyzed all available relevant information to determine whether there is new information that was not available at the time of EIR No. 331, indicating that a new significant effect not reported in that document may occur. Based on the information and analyses above, there is no substantial new information indicating that there would be a new significant impact related to population and housing requiring major revisions to EIR No. 331.

3.11.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR There is no new information, mitigation, or alternatives to the Proposed Project that would substantially reduce one or more significant impacts pertaining to population and housing identified and considered in EIR No. 331.

3.11.5 Standard Conditions and Mitigation Measures
EIR No. 331 found that the Approved Project would not result in significant impacts relating to population and housing and no Standard Conditions or mitigation measures were identified.

Further, as previously discussed, the Proposed Project does not include any residential development that would necessitate the adoption of new mitigation measures pertaining to population and housing.

3.12.1.10 Landfills
The County of Orange owns and operates three active landfills. These are Olinda Alpha Landfill near Brea, the Frank R. Bowerman Landfill near Irvine, and the Prima Deshecha Landfill in San Juan Capistrano. In order to ensure that the maximum permitted daily tonnage at a particular landfill is not exceeded, refuse trucks may have to transport material to one or the other. In October 2020, the anticipated landfill closure date for the Olinda Alpha Landfill was extended to 2036 due to increased recycling and waste diversion.

3.12.2 Comparison of Impacts for the Approved Project and the Proposed Project Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which would cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for i) fire protection services, ii) police protection services, iii) schools, or iv) library services? Approved Project
Fire Protection
Less Than Significant Impact. Development of the Approved Project included the conversion of undeveloped land in a hillside area to primarily residential land uses. As a result, the Approved Project would result in the increase in the demand for fire protection services provided by the City of Anaheim. As described in EIR No. 331, the Approved Project included the development of a fire station within DA 6 and implementation of additional fire protection features, such as a fuel modification plan, access design for emergency vehicles, and building features. With the provision of a fire station within DA 6, service levels provided by the Anaheim Fire Department to areas within the city would not be impacted, and the response times in the vicinity of the project would be decreased. The fire station site would have been within the Approved Project area and was included in the analysis of potential environmental impacts associated with development of the Approved Project and was addressed in the respective sections of EIR No. 331. In addition, EIR No. 331 prescribed Standard Condition (SC) 12-1 requiring the property owner/developer to demonstrate that each tentative tract or parcel map has been prepared in complain with applicable provisions of the Anaheim Municipal Code and Specific Plan related to fire prevention and suppression, which would be subject to the review and approval of the Fire Department. With implementation of SC 12- 1, EIR No. 331 determined that potential impacts on fire protection services would be less than significant.

Police Protection
Less Than Significant Impact. Implementation of the Approved Project included the development of a maximum of 2,500 residential units and would increase the City’s population by approximately 8,250 residents (assuming 3.3 people per dwelling unit). Based on the established service ratio of

the City of 1.0 sworn officer per 1,000 residents, EIR No. 331 determined that the Approved Project would generate the need for approximately eight officers in order to maintain current officer-to- population ratios and continue to provide consistent level of service to the Approved Project area and remainder of the City. The City of Anaheim Police Department would ultimately determine the timing and number of new officers hired as part of its standard staffing practices. The funding for new officer positions needed to maintain acceptable citywide police protection service levels would have come from the City’s General Fund Property taxes and other fees assessed on future property owners in the residential community developed through implementation of the Approved Project would contribute to the General Fund revenues. Additionally, EIR No. 331 prescribed SC 12-2, requiring the property owner/developer to contribute to the citywide Police Facilities Capital Improvement Fee Program.

Overall, EIR No. 331 determined that existing police department facilities were sufficient to provide police protection services to the Approved Project area. As such, the Approved Project would not result in the need for a new police facility. Therefore, EIR No. 331 determined that the Approved Project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, or the need for new or physically altered governmental facilities, the construction of which would cause significant environmental impacts. With implementation of SC 12-2, EIR No. 331 determined that potential impacts on police protection services would be less than significant.

Public Schools
Less Than Significant Impact. Implementation of the Approved Project included the development of a maximum of 2,500 residential units and would increase the City’s population by approximately 8,250 residents (assuming 3.3 people per dwelling unit). As previously noted, the Approved Project included the reservation of a minimum 10-acre school site in DA 3, as specified in PDF 12-1. The Orange Unified School District (OUSD) would have been required to comply with all requirements of the California Department of Education concerning the acquisition and construction of a school at the proposed location.

EIR No. 331 evaluated the potential impacts (traffic, air quality, utilities, etc.) associated with the development of a school within the Development Area 3 of the MPSP. The Approved Project allowed for the transfer of units to DA 3 from other DAs if the traffic generated by the transferred units did not exceed the amount of traffic that would be generated by a school with 800 students (as assumed in the traffic analysis prepared for the project). However, the total unit count of 2,500 would not be exceeded. In addition, EIR No. 31 prescribed SC 12-3, requiring the property owner/developer to enter into a School Impact Mitigation Agreement with the OUSD in order to mitigate impacts to the school district. With implementation of PDF 12-1 and SC 12-3, EIR No. 331 determined that potential impacts on public schools would be less than significant.

Libraries
Less Than Significant Impact. Implementation of the Approved Project and the associated increase in population would increase demand on the City’s libraries, with the Canyon Hills Library likely to be the most affected due to its proximity to the Specific Plan Area. The library would be planned to 3-143

benefit all development in the East Santa Ana Canyon area, which includes the Approved Project site.

The City of Anaheim Public Library Services Division has determined the existing Canyon Hills library would be inadequate to serve the approved and proposed development in the Anaheim East Santa Ana Canyon area, including the Approved Project.

The Library Services Division had plans to develop a new library west of Weir Canyon Road on the site of the existing East Anaheim Police Station. The area of benefit for the proposed library is the area located south of SR-91 and east of Mohler Drive and Canyon Rim Road. This area includes The Highlands at Anaheim Hills, The Summit of Anaheim Hills, and Sycamore Canyon. The Approved Project is also included within the area of benefit. All developments within the area of benefit are required to pay fees for the proposed library, in accordance with City Council Resolution 89R-235 (June 13, 1989) as may hereinafter be amended, which adopted the Public Library Facilities Plan for the East Santa Ana Canyon area, and in conjunction with Chapter 17.08, Section 17.08.385 of Anaheim Municipal Code. The existing communities of The Highlands at Anaheim Hills, The Summit of Anaheim Hills, and Sycamore Canyon were expected to pay the required fees. As the Approved Project is within the area of benefit, the Approved Project would be required to pay fees for the construction of library facilities in the East Hills Planned Community, as specified in SC 12-14. With implementation of SC 12-14, EIR No. 331 determined that potential impacts on library services would be less than significant.

Proposed Project
Fire Protection
Less Than Significant Impact. The Approved Project considered large-scale residential development within DA 5. At that time a new fire station was proposed within the Approved Project area that would provide fire protection for this area. While implementation of the Proposed Project would not preclude the development of residential uses within DA 5, implementation of the Proposed Project would develop DA 5 with two cemeteries as a conditional use. With the proposed change in land use to from residential to cemetery uses within DA 5, the potential risk to person and property is substantially reduced. Construction of the fire station could be pursued in the future if determined warranted. An administration building and a building associated with the maintenance yard are proposed but would not require additional fire protection services beyond what the City currently provides for the area as development of the two buildings would not induce a substantial population increase at the site. Compliance with all applicable Anaheim Fire Department standards and regulations would be incorporated into the design of the Proposed Project to address fire protection of any structures. Compliance with City of Anaheim Council Policy No. 5.3 (Hillside Grading), which includes provisions for fuel modification plans per Anaheim Fire Department’s municipal codes and standards. Further, planting plans associated with the Proposed Project would comply with Anaheim Fire Department’s Acceptable Planting Species guidelines. Therefore, implementation of the Proposed Project would result in less than significant impacts associated with fire protection services, and SC 12-1 would not be applicable to the Proposed Project.

Police Protection
Less Than Significant Impact. The Approved Project anticipated large-scale residential development within the Approved Project area and identified the potential need for eight additional police officers. This need was associated with the generation of 8,250 additional residents facilitated by the Approved Project’s development of up to 2,500 dwelling units and commercial land uses within DA 6. With the construction of the proposed cemeteries rather than the 1,595 units planned within DA 5, the Proposed Project would not result in an identified need for additional police services. As previously stated, operations of the Proposed Project are anticipated to generate approximately 12 jobs, which may necessitate additional police presence. However, the Proposed Project would ultimately result in a reduced scale of residential development within the Specific Plan Area as a whole and, as such, would reduce the need for additional police officers from what was analyzed in EIR No. 331. Therefore, implementation of the Proposed Project would result in less than significant impacts associated with police protection services, and SC 12-2 would not be applicable to the Proposed Project.

Public Schools
Less Than Significant Impact. The Approved Project anticipated large-scale residential development within the Approved Project and identified the potential need for a school site. This school site was planned within DA 3 of the Approved Project area. The need for the development of a school was associated with the addition of approximately 1,045 cumulative K-12 students, to the Approved Project area and the Orange Unified School District under the Approved Project. While implementation of the Proposed Project would not preclude the development of residential uses within DA 5, implementation of the Proposed Project would develop DA 5 with two cemeteries as a conditional use. With the proposed change in land use to from residential to cemetery uses, the Proposed Project would reduce the demand for a new school within the Specific Plan Area.

Therefore, implementation of the Proposed Project would result in less than significant impacts on public schools, and PDF 12-1 and SC 12-3 would not be applicable to the Proposed Project.

Libraries
Less Than Significant Impact. The Approved Project anticipated large scale residential development within the Approved Project area and identified the potential need for a new library. While implementation of the Proposed Project would not preclude the development of residential uses within DA 5, implementation of the Proposed Project would develop DA 5 with two cemeteries as a conditional use. With the proposed change in land use to from residential to cemetery uses, the Proposed Project would reduce, if not eliminate, the need for additional library services identified under the Approved Project. Therefore, implementation of the Proposed Project would result in less than significant impacts on library services and SC 12-14 would not be applicable to the Proposed Project.

Would the project have insufficient water supplies available to serve the project (including large scale developments as defined by Public Resources Code Section 21151.9 and described in Question No. 20 of the Environmental Information Form) from existing entitlements and resources, or are new or expanded entitlements are needed?

Would the project require or result in the construction of new water facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Approved Project
Less Than Significant Impact with Mitigation Incorporated. In 2001, SBs 610 and 221 were enacted to require coordination between land use decisions and information on water supply. SB 610 requires preparation of water supply assessments (WSAs) as part of the environmental documentation for certain projects as defined in Water Code Section 10912 [a], and SB 221 requires affirmative written verification that sufficient water supply is available for certain residential subdivisions. The Approved Project involved a Specific Plan amendment and required the preparation of a WSA. A WSA was prepared for the Approved Project. Water Verifications (WVs) would have been required prior to approval of individual tentative tract maps.

Based on the City’s historical water use factors, the Approved Project was anticipated to generate an average-day water demand for residential and non-residential uses (school, fire station, and trail staging area) of approximately 1.38 million gallons per day (MGD) and irrigation water demand of

0.54 MGD, with a total demand of 1.92 MGD.

The City of Anaheim’s Rule 15C requires terminal storage (emergency supply) in the eastern reaches of the City’s service area, in addition to basic storage volume. Terminal storage is typically 150 percent of the maximum day demand; however, the terminal storage requirement for the Approved Project was reduced to exclude common-area landscaping demands. This exclusion was based on the provision of irrigation systems that would be controlled by automatic programmable irrigation controllers that utilize California Irrigation Management System (CIMIS) Data to adjust water times and durations based on daily evapotranspiration data, as detailed in PDF 12-3. Communitywide irrigation control would be provided by a centralized irrigation control system designed to separately valve hydrozones based on plant water requirements, exposure, and terrain characteristics. To compensate for the reduction in the size of the terminal storage reservoir, the City would have had the capability to turn off irrigation services in the event of an emergency. The terminal storage requirement for the original project was approximately 3.9 MG.

The City of Anaheim commissioned preparation of a WSA for the Approved Project to determine whether or not the City of Anaheim Public Utilities Department would have had sufficient water to serve the Proposed Project, including dry hydrologic periods of up to 3 years for the next 20 years.

Water demands under ultimate buildout conditions were considered in the WSA. The WSA concluded that there was sufficient available water supplies for the Approved Project for the next 20 years, including during drought conditions.

The water distribution system as part of the Approved Project would have included water lines, pump stations, and reservoirs designed and constructed as part of the Approved Project, specifically to accommodate the water supply for the Approved Project. The majority of the distribution facilities would be constructed within the Specific Plan Area; however, connections to off-site water lines would have been required. The on-site water facilities, including 750-, 900-, and 1,320-foot- zone reservoirs, would have occurred within the identified development footprint evaluated throughout EIR No. 331. No additional impacts related to construction and operation of the on-site water distribution system would have occurred.

Installation of these water supply facilities were not part of the Approved Project and the impacts associated with the facilities were not considered impacts of the Approved Project. The impacts of constructing the OCWD water supply facilities were addressed in the OCWD EIR.

The Approved Project also included PDF 12-2, which required the property owner/developer to submit water improvement plans prepared in conformance with the Approved Project’s Water System Sub Area Master Plan (SAMP) to the Public Utilities Department for review and approval.

In addition, EIR No. 331 prescribed SC 12-4, requiring water verification studies from the Public Utilities Department to confirm sufficient water supply in accordance with SB 221; SC 12-5, requiring the property owner/developer to demonstrate to the Public Utilities Department that water consumption reduction measures have been implemented; Mitigation Measure (MM) 12-1, requiring payment of a proportionate share of water supply source to the Public Utilities Department to meet the project increases in water demand in accordance with Rule 15C; MM 12-2, requiring a Traffic Management Plan for street improvements; and MM 12-3, requiring a utility layout and trenching plan for existing public streets. With implementation of PDFs 12-2 and 12-3, SCs 12-4 and 12-5, and MMs 12-1, 12-2, and 12-.3, EIR No. 331 determined that potential impacts related to water service and supply would be less than significant.

Proposed Project
Less Than Significant Impact with Mitigation Incorporated. As identified in the Project Description, three separate on-site services for fire protection, domestic and irrigation water would be provided to both the upper and lower pads and would be conveyed within a single 20” water line point of service provided by Anaheim Water Department on Santa Ana Canyon Road. The three separate services would be connected at the project entry and located within the typical easement section of the exterior access road. The 20” main water line would connect to the existing 30-inch line located off-site in Santa Ana Canyon Road, near Woodcreek Road. Submeters would be provided for the fire, domestic and irrigation lines between the parcels / cemeteries. Two irrigation booster pump stations would be constructed on site to assist in conveying water. Alternatively, a groundwater well may be constructed on site to provide potable water and irrigation services to both cemeteries. The location and depth of the well is currently being evaluated. On-site water pipelines would be connected to the groundwater well within the property. If a groundwater well is constructed on site to provide potable water, the project applicant would be required to obtain a permit from the State Water Resources Control Board. There currently are no reclaimed water lines in this portion of the City and all activities on site would utilize potable water or well water as an alternative.

If the Proposed Project constructs a groundwater well, a water tank reservoir would be required in the northeast corner of the project site to meet project demand for landscape irrigation services and potable water at the administrative building, committal shelter, and maintenance facility on the lower pad and similar facilities on the upper pad. The proposed tank would be 75 feet in diameter and 40 feet high, providing a minimum of 672,000 gallons of storage capacity. The 680-foot-zone reservoir would be located and designed in a manner which screens it from public view pursuant to community design guidelines specified in the City’s Mountain Park Specific Plan. The need for and sizing of any reservoir would be subject to analysis of water demand associated with maximum day irrigation, on-site buildings, and fire flow requirements. 3-147

As identified in EIR No. 331, water demand for the Approved Project was determined to be 1.92 MGD (1.38 MGD for residential/non-residential water demand and 0.54 MGD for irrigation water demand) and was based on the City’s historical water use factors at the time EIR No. 331 was prepared. As provided in the Preliminary Water Study for Gypsum Canyon Cemetery,9 which was approved by the City in 2024, the Proposed Project is anticipated to have a water demand of 2.2 MGD for irrigation services for both cemeteries and 0.04 MGD for domestic uses (potable water at the administrative building, committal shelter, and maintenance facility, for a total of 2.24 MGD.

According to the City’s Urban Water Management Plan (UWMP), Anaheim depends on a combination of imported and local supplies to meet its water demands and has taken numerous steps to ensure it has adequate supplies. Further, the City’s UWMP indicates that there is sufficient supply to meet projected demand associated with buildout of the City’s General Plan due to diversified supply and conservation measures. In addition, Metropolitan’s 2020 UWMP finds that Metropolitan can meet full-service demands of its member agencies from 2020 through 2045 during normal years, single dry years, and multiple dry years. Therefore, although the anticipated water demand for the Proposed Project is slightly greater than the water demand identified for the Approved Project, the City anticipates adequate water supply for the Proposed Project. In addition, the Proposed Project would be required to prepare and submit a Water Supply Assessment prior to Final Map recordation and would be required to implement SC 12-4, requiring water verification studies from the Public Utilities Department to confirm sufficient water supply in accordance with SB 221. Therefore, no new impact to water supply would occur beyond what was previously identified.

Further, the Proposed Project would implement PDFs 12-2, requiring submittal of water improvement plans prepared in conformance with the SAMP; PDF 12-3, requiring irrigation systems be controlled by automatic programmable irrigation controllers; SC 12-5, requiring the property owner/developer to demonstrate to the Public Utilities Department that water consumption reduction measures have been implemented; MM 12-2, requiring a Traffic Management Plan for street improvements; and MM 12-3, requiring a utility layout and trenching plan for existing public streets. With implementation of PDFs 12-2 and 12-3, SCs 12-4 and 12-5, MMs 12-2 and 12.3, potential impacts related to water service and supply with development of the Proposed Project would be less than significant, similar to the Approved Project.

Would the project result in a determination by the wastewater treatment provider which serves or may serve the project that it has inadequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Would the project require or result in the construction of new wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

Approved Project
Less Than Significant Impact with Mitigation Incorporated. Collection of wastewater generated by the Approved Project would be the responsibility of the City of Anaheim, while OCSD would be responsible for regional conveyance and treatment of the wastewater through the Santa Ana Regional Interceptor (SARI) pipeline to the Fountain Valley Regional Wastewater Treatment Plant.

Because both of these agencies are involved in the collection and/or treatment of wastewater, anticipated wastewater flows for the Approved Project were calculated based on each agency’s methodology. Using the prescribed methodology, the Approved Project would generate an average daily wastewater flow of approximately 0.99 MGD assuming the City of Anaheim generation factors, and 0.91 MGD assuming the OCSD generation factors. The on-site collection systems would have been constructed to accommodate the anticipated sanitary sewer wastewater flow; therefore, both the east and west basin systems would have been of appropriate sizing and configuration to accommodate the sanitary sewer flows from the Approved Project.

The sanitary sewer lines in The Summit of Anaheim Hills were designed to accommodate 161,200 gallons per day from the Mountain Park project site. As noted in EIR No. 331, approximately 90,367 gallons of wastewater per day would have been generated by Approved Project uses west of SR-241 and would need to be accommodated in the existing sanitary sewer lines.

A pipe capacity constraint existed downstream in an existing 8-inch pipe segment on Running Springs Drive. The capacity constraint in this pipe segment, approximately 200 feet in length, would require upsizing to a 10-inch pipe diameter. All other existing sanitary sewer pipelines in the Summit Community have the existing capacity to receive west basin (DAs 3 and 7) wastewater flows from the Specific Plan Area.

There are currently no local sewer lines in the vicinity of the Approved Project site to serve wastewater flows from the east basin; however, the SARI pipeline is less than 0.5 mile from the project site. The Approved Project would require construction of sewer lines to connect to the SARI line. There is sufficient capacity in the SARI line to accommodate the wastewater from the Approved Project. As previously noted, the OCSD Strategic Plan accommodates the wastewater previously estimated to be generated by the Approved Project (approximately 3.7 MGD). The Approved Project would generate less than 1 MGD of wastewater. Therefore, the SARI line would have sufficient capacity to accommodate the wastewater generated by the Approved Project, even if it is necessary for all of the wastewater from the Approved Project (west and east basins) to be handled by facilities east of SR-241. During preparation of its updated Master Plan, OCSD hydraulically modeled the SARI pipeline in the vicinity of the project site and concluded that there was sufficient capacity in the SARI pipeline to receive Approved Project flows.

The installation of local sewer lines to deliver wastewater to the SARI line is included as part of the Approved Project and these facilities would be sized to accommodate the estimated sanitary sewer flows from the Approved Project. Additionally, sanitary sewer lines would be installed in the street rights-of-way and the direct impacts associated with installation of these facilities were addressed in EIR No. 311.

The Approved Project also included PDF 12-4 requiring the property owner/developer to conduct sewer monitoring at two similar developments within the City to verify sewer generate rates. In addition, EIR No. 331 prescribed SCs 12-6 and 12-7, requiring the payment of fees to the City of Anaheim and OCSD for sewer service and sewer connections; MM 12-4, requiring approvals, permits and/or easement rights of way from private property owners for off-site wastewater line connections in DAs 1, 2, 4, and 5; and MMs 12-5 and 12-6, requiring the submittal of sewer improvement plans for development within all development areas. With implementation of PDF 12- 4, SCs 12-6 and 12-7, and MMs 12-4, 12-5, and 12-6, EIR No. 331 determined that potential impacts related to wastewater service and supply would be less than significant.

Proposed Project
Less Than Significant Impact. On-site sewage would be collected via pipelines and conveyed to on- site holding tanks with the upper and lower pads. These holding tanks would be regularly monitored and cleaned out, as needed, with a vacuum truck. This configuration for sewer collection would eliminate the need to connect to local sewer lines for transport to a local treatment plant. The limited quantities of sewage collected on site would be delivered by truck to one of the local wastewater treatment plants for treatment. Because the Proposed Project would not connect to local sewer lines for transport to a local treatment plant, PDF 12-4, SCs 12-6 and 12-7, and MMs 12- 4, 12-5, and 12-6, would not be applicable to the Proposed Project.

There would be no new impact to wastewater treatment capacity and impacts would be less than significant, similar to the Approved Project.

Would the project result in the need for new systems or supplies, or substantial alternations related to i) electricity, ii) natural gas, iii) telephone service, or iv) cable television service/reception? Approved Project
Electricity
Less Than Significant Impact with Mitigation Incorporated. The proposed electric system for the Approved Project was described EIR No. 311 and was based on the electric demand assuming no diversity. The estimated annual electrical consumption for the Approved Project, excluding institutional uses in DA 6, was 21.8 million kilowatt-hours (kWh), which equates to approximately 8,726 kWh per year per residential unit. While sufficient power and distribution capabilities exist to provide the Approved Project with electrical service, APU does not currently have any 66-kilovolt (kV) transmission circuits or 12kV distribution circuits within the project area. Therefore, APU has determined that new electrical infrastructure, on and off site, would be required to accommodate growth in the Approved Project area.

In addition to the construction of new facilities on site, Approved Project included the removal of existing electrical facilities operated by SCE. Subsequent to the closure of Robertson’s, SCE would remove the on-site overhead power lines serving the quarry site. The identified impact areas for construction/installation of new facilities and removal of existing facilities were within the Approved Project impact area, and the potential impacts of these facilities were addressed throughout EIR No. 331. The new electrical service would be supplied by the Anaheim Public Utilities Department.

3-150
Additionally, EIR No. 331 determined that the Approved Project would not materially impact the ability of the City of Anaheim’s system to serve the new and existing loads. The electric system would have been constructed for the Approved Project to accommodate the demands of the Approved Project
In addition, the Approved Project included PDF 12-5 requiring the submittal of electric system plans to the Public Utilities Department demonstrating conformation with the Public Facilities Plan of the MPSP.

EIR No. 331 also prescribed SC 12-8, requiring the property owner/developer to secure on-site electrical facilities in accordance with the City of Anaheim Public Utility Electric Rates, Rules, and Regulations; SC 12-9, requiring compliance with all State Energy Insultation Standards and City codes (i.e., Title 24 standards); SC 12-10, requiring payment of fees for electrical residential and commercial services; SC 12-11, requiring the incorporation of energy saving practices into building plans; MM 12-7, requiring submittal of a Traffic Management Plan for construction of utility improvements in roadways; MM 12-8 and 12-9, requiring submittal of preliminary electric system plans to the Public Utilities Department for development within DAs 3 and 7 and east of SR-241; and MM 12-10, requiring the payment of fees and the provision of the necessary infrastructure or installation of the electrical and communication systems.

With implementation of PDF 12-5, SCs 12-8 through 12-11, and MMs 12-7 through 10, EIR No. 331 determined that implementation of the Approved Project would not result in any impacts related to electrical service demand.

Natural Gas
Less Than Significant Impact. The Approved Project included the development of a maximum of 2,500 residential units, a fire station, a public community park, a school site, an interpretive center/store concession, a private recreation center and smaller private parks, and riding and hiking trails. The residential component of the Approved Project was estimated to consume 1.85 to 2.31 million therms annually. It should be noted that this amount did not include the nonresidential uses proposed as part of the Approved Project as SoCalGas does not compile consumption rates for these types of uses.

The natural gas for the Approved Project area would be provided via connections to existing off-site pipeline interceptions. A sole gas trench would be constructed and an 8-inch gas pipeline would be installed within the study area along Gypsum Canyon Road to serve DAs 1, 2, 4, and 5. DAs 3 and 7 would be served by an 8-inch natural gas pipeline installed in a sole gas trench extending from Weir Canyon Road.

The pipeline dimensions, location on the street, and buried depth were planned to vary from location to location and as determined by SoCalGas. Coordination between the property owner/developer and SoCalGas would occur to avoid any notable service disruptions during extension, relocation, and upgrading of services and facilities as well as to comply with California energy conservation requirements specified in California Administrative Code Title 24/25. In 3-151

A N A H E I M, C A L I F O R N I A

addition, the Approved Project included PDF 12-6 requiring the submittal of natural gas plans to the Public Utilities Department demonstrating conformation with the Public Facilities Plan of the MPSP.

Installation of on-site natural gas facilities would occur during project construction and would not result in any environmental impacts beyond those identified for construction of the project as addressed in the respective sections of EIR No. 331.

In addition, EIR No. 331 prescribed SC 12-12, requiring the property owner/developer to secure on- site natural gas facilities in coordination with SoCalGas.

With implementation of PDF 12-6 and SC 12-12, EIR No. 331 determined that implementation of the Approved Project would result in less than significant impacts on natural gas service or facilities.

Telecommunication Facilities
Less Than Significant Impact. EIR No. 331 determined that telecommunication service for the Approved Project would have been provided without any adverse impact on SBC’s ability to provide telephone service in the area. Prior to construction, existing overhead facilities along Gypsum Canyon Road would be temporarily relocated to allow for grading and installation of the new underground system. Subsequent to the closure of Robertson’s, the overhead lines would need to be removed and located underground.

To serve the Approved Project, trenches, conduit, and substructures would be installed from the entrance of DAs 1, 2, 4, and 5. DAs 3 and 7 would be served by trenches, conduit, and substructures installed along Weir Canyon Road. As discussed previously for other utilities, on-site telephone facilities would be constructed within the Approved Project impact area analyzed throughout EIR No. 331. Overall, EIR No. 331 determined that implementation of the Approved Project would result in less than significant impacts on telecommunication facilities.

Cable Television Service/Reception
Less Than Significant Impact. Service to the Approved Project can be provided without any adverse impact on Adelphia’s ability to provide telecommunication service in the area. Within the Approved Project area, cable television conduits would be installed in joint trenches along with the electrical and telephone conduits for distribution to the DAs. Joint trench design would be provided by cable provider once specific development plans became available. Overall, EIR No. 331 determined that implementation of the Approved Project would result in less than significant impacts on cable television service and reception.

Proposed Project
Electric
Less Than Significant Impact. As described in the Project Description, electricity would be provided to the project site via the existing Park Substation. The Park Substation was built anticipating an electrical supply need in the eastern areas of Anaheim. The site developer would be responsible for duct bank routing and installation cost from Park Substation to DA 5. The first route would be along Santa Ana Canyon Road and loop to existing system in Oak Canyon Rd. The second route would be

3-152
along Santa Ana Canyon Road and looped to existing system in Weir Canyon Road. All electrical transmission facilities entering the project site from off-site would be provided in underground conduit to both the upper and lower pads within the exterior entry road cross section.

Once on site, the electrical transmission facilities would connect to a 480/277-volt transformer, which would allow electricity to be distributed on site to buildings, roadway safety lighting, the existing flagpole and miscellaneous site lighting.

While implementation of the Proposed Project would not preclude the development of residential uses within DA 5, implementation of the Proposed Project would develop DA 5 with two cemeteries as a conditional use. With the proposed change in land use to from residential to cemetery uses, the Proposed Project would greatly reduce the anticipated electrical demand. The Proposed Project would develop DA 5 with a public cemetery and a State veterans cemetery, with some accessory buildings such as an administrative building and building associated with the maintenance yard.

Electrical demand associated with the Proposed Project would primarily be associated with lighting of the cemetery, the existing flagpole, and accessory buildings. Compared to the electrical demand of the Approved Project within DA 5, which consisted of 1,595 residential units, the electrical demand of the cemetery and accessory buildings would be minimal. As such, implementation of the Proposed Project would not create an additional, or increased, impact from what was considered under the Approved Project.

In addition, the Proposed Project would implement PDF 12-5, SCs 12-8, 12-9, and 12-11, and MMs 12-7 and 12-10, as described above. SC 12-10 would not apply to the Proposed Project as there would be no residential or commercial development within DA 5 and MMs 12-8 and 12-9 would not apply as the Proposed Project does not include development of DAs 3 or 7, or development east of SR-241. With implementation of PDF 12-5, SCs 12-8, 12-9, and 12-11, and MMs 12-7 and 12-10, impacts related to electrical service demand would be less than significant, similar to the Approved Project.

Natural Gas
Less Than Significant Impact. Natural gas usage with implementation of the Approved Project was associated with the previously proposed residential uses at the site. The Proposed Project would develop the site with two cemeteries and is not expected to use natural gas. Therefore, implementation of the Proposed Project would result in less natural gas usage as compared to the Approved Project. As such, implementation of the Proposed Project would not create an additional, or increased, demand compared to what was considered under the Approved Project.

Because the Proposed Project is not expected to use natural gas, PDF 12-6 and SC 1-12 would not apply to the Proposed Project. Impacts related to natural gas service and facilities would be less than significant, and less than the Approved Project.

Telecommunications
Less Than Significant Impact. Demand for telecommunication services with implementation the Approved Project was primarily associated with the previously proposed residential uses at the site.

Although the Proposed Project would require telecommunication services from a local provider 3-153

(currently Spectrum) for use in the administration building and potentially the maintenance building, as the Proposed Project would develop the site with two cemeteries as opposed to residential uses, the need for telecommunications services within DA 5 would be substantially less.

Therefore, implementation of the Proposed Project would not create an additional, or increased, impact from what was considered under the Approved Project. Impacts related to telecommunication service and facilities would be less than significant, and less than the Approved Project.

Would the project be served by a landfill with insufficient permitted capacity to accommodate the project’s solid waste disposal needs?
Would the project comply with Federal, State, and local statues and regulations related to solid waste?
Approved Project
Less Than Significant Impact. EIR No. 331 estimated a generation rate of 4,287.8 tons (4,215.8 tons/year for residential, and 72 tons for the school) of solid waste annually. The Orange County Integrated Waste Management District (OCIWMD) indicated that adequate capacity for the Approved Project was available within the Orange County landfill system, which includes three active landfills. Therefore, no significant impacts related to landfill capacity would result from implementation of the Approved Project.

It should also be noted that the City of Anaheim complies with all federal, State, and local statutes and regulations related to solid waste. Assembly Bill 939 requires that after 2000, the City of Anaheim divert at least 50 percent of solid waste from landfills through conservation, recycling, and composting. In 2000, the City diverted 50 percent of its solid waste, as required (City of Anaheim 2004). This was achieved through City participating in over 20 programs such as residential curbside recycling to facilitate the diversion of waste from landfills. As identified in the Green Element of the City’s General Plan, the City has also adopted a Source Reduction and Recycling Element (SRRE) and a Household Hazardous Waste Element (HHWE) (part of the Orange County Integrated Waste Management Plan) to develop programs to address household hazardous waste State law.

EIR No. 331 prescribed SC 12-13, requiring submittal of a Solid Waste Management Plan with recycling capabilities to the Department of Public Works for review and approval. With implementation of SC 12-13, EIR No. 331 determined impacts associated with landfills and solid waste would be less than significant.

Proposed Project
Less Than Significant Impact. Demand on landfill facilities with implementation of the Approved Project was primarily associated with the previously proposed residential uses at the site. Although the Proposed Project would generate some solid waste during operation, as the Proposed Project would develop the site with two cemeteries as opposed to residential uses, the need for landfill services would be substantially less when compared to what was analyzed in EIR No. 331 for DA 5.

Therefore, implementation of the Proposed Project would not create an additional, or increased, impact from what was considered under the Approved Project.

3-154
Given the proposed change in development type within DA 5, the Proposed Project would result in a substantial reduction in demand for public services and utilities from what was identified for the Approved Project. In addition, SC 12-13, requiring submittal of a Solid Waste Management Plan with recycling capabilities to the Department of Public Works for review and approval, would remain applicable to the Proposed Project. With implementation of SC 12-13, impacts associated with landfills and solid waste would be less than significant, similar to the Approved Project.

Would the project conflict with any applicable land use 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, or zoning ordinance) adopted for the purpose of avoiding or mitigation an environmental effect?
Approved Project
Less Than Significant Impact. EIR No. 331 identified goals and policies in the City of Anaheim General Plan Public Services and Facilities Element that would be applicable to the Approved Project. In addition, EIR No. 331 indicated that a NOP comment letter from SCAG identified several policies from the Growth Management Chapter as being relevant to the Approved Project regarding public services and utilities. The identified goals and policies from the Public Services and Facilities Element include providing sufficient staffing, equipment, and facilities for fire protection, police protection, electricity, water, wastewater, solid waste, natural gas, and education. The identified policies form the SCAG Growth Management Chapter include encouraging patterns of development which reduce costs on infrastructure and supporting local jurisdictions and service providers in their efforts to develop sustainable communities and provide accessible and effective services such as public education, housing, healthcare, social services, recreational facilities, law enforcement, and fire protection.

EIR No. 331 included a consistency analysis with the City of Anaheim General Plan Public Services and Facilities Element and the policies from the Growth Management Chapter identified by SCAG based on the analysis of previous significance thresholds in Section 4.12, Public Services and Utilities, of EIR No. 331 and determined that the Approved Project would not conflict with any of the identified goals and/or policies. Impacts related to conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the Approved Project would be less than significant, and no mitigation was identified.

Proposed Project
Less Than Significant Impact. As discussed throughout this section of the Addendum, the Proposed Project would not result in insufficient staffing, equipment, and facilities related fire protection, police protection, electricity, water, wastewater, solid waste, natural gas, and schools. In addition, the Proposed Project would not result in substantial infrastructure construction to meet the needs of the Proposed Project. Therefore, the Proposed Project would not conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the Proposed Project, similar to the Proposed Project.

3.12.3 Cumulative Public Services and Utilities Impact
Approved Project
Less Than Cumulatively Considerable Impact. The cumulative study area for public services and utilities would be the service area for service and utility providers, which can range from a neighborhood to an entire region. EIR No. 331 found that in combination with other projects in the cumulative study area, the Approved Project would result in an increased demand for public services and utilities. Generally, the various service agencies incorporate growth anticipated in the adopted General Plan into their long-range planning programs. Impacts to public services resulting from cumulative project development would be mitigated by the individual projects to ensure that acceptable service levels are maintained pursuant to State CEQA Guidelines. Standard measures such as the payment of fees and incorporation of needed facilities have been or would be addressed for each project as determined appropriate in individual environmental analyses. Should it be determined that additional public service and/or utility facilities are required to accommodate the needs of the City, individual construction projects would be subject to review under CEQA. Potential impacts from the facilities would need to be addressed, and mitigation developed, as necessary.

EIR No. 331 noted that the Approved Project would not require the construction of additional public services or utility facilities beyond those proposed as part of the original project and analyzed in EIR No. 331. The Approved Project therefore would not have a significant impact related to public services and utilities. Because individual development projects within the cumulative study area would be responsible for their individual incremental public service and utility contributions and because the Approved Project’s impacts would be individually less than significant, EIR No. 331 determined that the Approved Project would not result in a significant cumulative contribution to public services or utilities.

Proposed Project
Less Than Cumulatively Considerable Impact. As with the Approved Project, the cumulative study area for public services and utilities would be the service area for each service and utility provider.

The cemetery uses proposed under the Proposed Project would generally decrease the demand for public services and utilities compared to the Approved Project, which determined that no cumulative impacts would occur under the residential buildout of DA 5. Further, as previously stated, each individual project within the cumulative study area would be required to address potentially considerable incremental utility and service demand increases pursuant to State CEQA Guidelines. Therefore, potential impacts on public services and utilities associated with the Proposed Project would not be cumulatively considerable, similar to the Approved Project.

3.12.4 Findings Related to Public Services and Utilities

3.12.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR Based on the foregoing analysis and information, there is no evidence that the Proposed Project requires a major change to EIR No. 331. The Proposed Project would not result in new significant environmental impacts related to public services and utilities, and there would not be a substantial increase in the severity of impacts described in EIR No. 331.

3.12.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR The currently proposed changes to the Specific Plan Area would greatly reduce the originally identified impacts outlined in EIR No. 331. The greatly reduced impacts would not require revisions to the analysis in EIR No. 331. There is no information in the record or otherwise available that indicates that there are substantial changes in circumstances pertaining to public services and utilities that would require major changes to EIR No. 331.

3.12.4.3 No New Information Showing Greater Significant Effects than the Certified EIR This Addendum has analyzed all available relevant information to determine whether there is new information that was not available at the time EIR No. 331 was certified that could indicate that a new significant effect not reported in that document may occur. Based on the information and analyses above, there is no substantial new information indicating that there would be a new significant impact related to public services and utilities requiring major revisions to EIR No. 331.

3.12.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR There is no new information, mitigation, or alternatives to the Proposed Project that would substantially reduce one or more significant impacts pertaining to public services and utilities identified and considered in EIR No. 331.

3.12.5 Standard Conditions and Mitigation Measures
Standard conditions (SC) 12-1 through 12-14 were prescribed to the Approved Project. Of these, SC 12-5 through 12-9, 12-11, and 12-13 would remain applicable to the Proposed Project, while the remaining standard conditions would pertain to residential-scale utilities and therefore would not be relevant to the proposed cemetery uses.

SC 12-5 Prior to final building and zoning inspections, the property owner/developer shall demonstrate to the Public Utilities Department that water consumption reduction measures have been implemented as required by State law and in accordance with the Water Utilities Rates, Rules and Regulations. Where appropriate, plans submitted for building permits shall include notes on plans that indicate the measures that will be utilized to reduce water consumption. Such measures where feasible and appropriate shall include, but are not limited to:
a. Low-flush toilets and urinals (Health and Safety Code Section 17921.3); b. Maximum flow rate of all new showerheads, lavatory faucets, and sink faucets (Title 20, California Code of Regulations Section 1604[f]); c. Appliances certified by manufacturer to comply with regulations established by applicable efficiency standards (Title 20, California Code of Regulations Section 1606[b]);
d. Public lavatories equipped with self-closing faucets that limit the flow of hot water (Government Code Section 7800);

f. Conservation reminders posted in rooms and restrooms; g. Thermostatically controlled mixing valve for bath/shower; and h. Implementation of efficient irrigation systems to minimize runoff and evaporation.

SC 12-8 Prior to approval of final tract or parcel maps, the property owner/developer shall install, bond for, or otherwise secure on-site electrical facilities in accordance with the City of Anaheim Public Utility Electric Rates, Rules and Regulations, and provide written evidence of this fact to the Public Utilities Department.

SC 12-9 The Proposed Project shall comply with all State Energy Insulation Standards Requirements (as part of the CBC), as adopted by and the City of Anaheim City Council, codes in effect at the time of application for building permits. (Commonly referred to as Title 24, these standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods. Among other things, Title 24 covers the use of energy efficient building standards, including ventilation, insulation and construction and the use of energy saving appliances, conditioning systems, water heating, and lighting.) Plans submitted for building permits shall include written notes demonstrating compliance with energy standards and shall be reviewed and approved by the Building Division as part of the plan review process prior to issuance of building permits.

SC 12-11 Prior to issuance of each building permit, the property owner/developer shall incorporate the following energy saving practices into building plans. The property owner/developer shall implement, to the extent feasible, these energy saving practices, in compliance with Title 10 of the Anaheim Municipal Code, prior to each final building and zoning inspection:
a. Consultation with the Public Utilities Department energy conservation experts for assistance with energy conservation design features. b. Use of electric motors designed to conserve energy.
c. Use of special lighting fixtures such as motion sensing light switch devices and compact fluorescent fixtures in place of incandescent lights. d. Use of T8 lamps and electronic ballasts. Metal halide or high-pressure sodium for outdoor lighting.

SC 12-13 Prior to approval of any site plans, tentative tract or parcel maps, the property owner/developer shall submit a Solid Waste Management Plan with recycling capabilities to the Department of Public Works, Streets and Sanitation Division for review and approval. Refuse collection and disposal for the Proposed Project shall comply with AB 939, SB 1383, the County of Orange Integrated Waste Management Plan, and the City of Anaheim Integrated Waste Management Plan.

Mitigation measures (MM) 12-1 through 12-10 were identified to reduce potentially significant impacts of the Approved Project. Of these, MM 12-2, 12-3, 12-7, and 12-10 would remain applicable to the Proposed Project. MM 12-1 would continue to apply to the Proposed Project; however, as the requirement to meet Rule 15C, which requires the property owner/developer shall pay the Public Utilities Department a proportionate share of a water supply source to meet the projected increases in water demands, expires in 2024, the mitigation measure would no longer be applicable after 2024. In addition, MM 12-6 would not apply to the Proposed Project as the Proposed Project would connect to local sewer lines for transport to a local treatment plant. The remaining MM would not be applicable to the Proposed Project as they pertain to residential-scale utilities, while the Proposed Project is concerned with cemetery uses.

MM 12-1 Prior to the issuance of the first building permit, the property owner /developer shall pay the Public Utilities Department a proportionate share of a water supply source to meet the projected increases in water demands in accordance with Rule

15.C, Section 3, of the Public Utilities Rates, Rules, and Regulations. Although the Water Supply Assessment concluded that there is adequate capacity to serve the Proposed Project, an additional water supply source will ensure that there is no loss of redundancy and/or reliability to the city water supply system.

MM 12-2 Prior to approval of street improvement plans, the property owner/developer shall submit Traffic Management Plans to the City of Anaheim Department of Public Works and Yorba Linda Public Works Department for proposed street improvements within the respective jurisdictions for review and approval.

3.13 RECREATION

3.13.1 Existing Environmental Setting
According to EIR No. 331, there are currently no recreational uses located on the project site. There is an existing unimproved trail which traverses the project site in a north-south direction and consists of an unimproved dirt road used for ranch operations on site. The trail is currently not accessible to the public and is within dedicated open space areas including The Nature Conservancy Anaheim Conservation Easement (TNC ACE) and the Natural Communities Conservation Plan/Habitat Conservation Plan (NCCP/HCP).

EIR No. 331 mentions there are there are over 2,000 acres of off-site recreational uses within the City of Anaheim and surrounding area that would serve future residents of the project site including a State Park, several county regional parks, and local parks. In addition to these park facilities, there are a variety of other public recreational opportunities within the local area, including biking, equestrian uses, hiking, and golfing. Existing and planned recreation facilities are discussed in accordance with the Proposed Project. Since certification of EIR No. 331, OC Parks has established the Gypsum Canyon Wilderness area to the east of the project site. Included within the Wilderness Area is the Gypsum Canyon Wilderness Trailhead located south of the Gypsum Canyon and East Santa Ana Canyon Road intersection. The Gypsum Canyon Trailhead is facilitated by OC Parks with a scheduled day use and has 5 separate trails that range from easy to moderate levels and can be utilized through hiking or mountain biking.

3.13.2 Comparison of Impacts for the Approved Project and the Proposed Project Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Approved Project
Less Than Significant Impact. The Approved Project is located near a variety of existing recreational uses, including parks, trails, and other facilities. Based off the previous analysis, the project was

expected to generate approximately 8,250 new residents in the City of Anaheim. The City’s General Plan identified park needs and areas within the City and utilized a ratio of two acres of parkland for every 1,000 residents. Based on the 8,250 new residents, the Approved Project was expected to generate 16.5 acres of publicly owned park and recreational areas in the City. The parkland demand generated by the Approved Project would be accommodated through the provision of an improved 15-acre community park within the Mountain Park Specific Plan DA 3, west of SR-241. This park would serve the future project residents as well as those in surrounding communities. This would be an active sports park providing facilities for tennis, basketball, softball, soccer, and football.

Additionally, the park would be adjacent to the proposed school site allowing for joint use of these public facilities. Although they do not count towards meeting the park fee credit, private recreation facilities, including a community recreation center, between DAs 4 and 5, one- and three-acre private recreation facilities within DAs 4 and 5; and five pocket parks (approximately 0.75 acre each) in DA 5 would be provided as part of the Approved Project.

Though the Approved Project included provisions that would enable future development within the Specific Plan Area, it also provides for the preservation of open space/natural habitat areas, which would connect to existing regional open space areas, including:
• Coal Canyon Biological Corridor to the east;
• Fremont Cayon and Weir Canyon to the south; and
• Featherly Regional Park to the north.

The Approved Project included implementation of recreational trails and bikeways. Specifically, a segment of the Gypsum Canyon Creek Trail, a public regional riding and hiking trail along Gypsum Canyon Creek, was proposed to be constructed and would connect to the Featherly Regional Park, Santa Ana River, and the existing unimproved Gypsum Canyon Creek Trails. This segment would be designed to County of Orange Standards and would serve equestrian uses, mountain bikes, and hiking. A trail staging area would be in DA 6. Class II on-road bikeways were proposed as part of the project and would provide a link to off-site bikeways that are either currently existing or are planned for construction in the future.

As mentioned in EIR No. 331, development of the Mountain Park Specific Plan Area with residential uses would increase demand on state, regional and local parklands and recreational areas in proximity to the project site; however, this increased demand would be accommodated primarily through provision of the on-site public and private recreation facilities described above. EIR No. 331 concluded that any increased demand on off-site park and recreational facilities would be negligible and that the Proposed Project would not cause deterioration of these facilities to occur or be accelerated.

Proposed Project
Less Than Significant Impact. The Proposed Project would construct a public cemetery and a State veterans cemetery within DA 5 of the MPSP. The cemetery use would not generate demand for park facilities. Furthermore, the Proposed Project would eliminate the dwelling units previously proposed and would result in a decreased demand on the neighboring recreational facilities and a reduced on- site parkland dedication requirement. The Proposed Project would thus not cause deterioration of 3-161

these facilities to occur or be accelerated. The conclusions of EIR No. 331 regarding the demand for recreational resources remain valid.

Would the project include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? Approved Project
Less Than Significant Impact. EIR No. 331 mentions the project would require the construction of new recreational facilities. As described previously, the Mountain Park project proposes development of a 15-acre public community park and associated amenities to fulfill the City’s parkland requirement for the project. The community park is part of the Proposed Project and the direct and indirect (visual and noise) impacts associated with construction and operation of the park have been addressed in the previous Visual and Noise sections of EIR No. 331. The project would not require the expansion of any existing recreational facilities. In addition to the proposed public community park, the project also includes a private recreation center, seven private parks, and five smaller “pocket parks”, riding and hiking trails, and Class II bikeways within the project boundaries.

It should be noted that the portion of the regional trail that follows Gypsum Creek is within the TNC ACE open space area and use of the trail would occur in compliance with the requirements established for these open space areas. Overall, EIR No. 331 found that the Approve Project would not include new recreational or expansion of existing recreational facilities that would have an adverse physical effect on the environment.

Proposed Project
Less Than Significant Impact. The Proposed Project would construct cemetery uses within DA 5. As there would be no residential development, the private recreational facilities previously identified would not be constructed. The Proposed Project proposes a 24-foot-wide OC Parks Trailhead access road and an entry gate to be constructed to provide continued access to the existing OC Parks Gypsum Canyon Wilderness trailhead. This access road would be constructed in accordance with OC Parks and City’s standards. The Proposed Project would not hinder access to the Gypsum Canyon Trailhead and the PDFs would be implemented to ensure the Proposed Project would not adversely affect the operation of the Gypsum Canyon Wilderness Area and the conclusions regarding impacts to recreational resources in EIR No. 331 remain valid.

Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for parks? Approved Project
Less Than Significant Impact. As described above, the Approved Project included both public and private recreational facilities to accommodate projected demand associated with the proposed development would not result in substantial adverse physical impacts associated with new or physically altered government facilities, need for new or physically altered government facilities and

construction of which could cause significant environmental impacts to maintain acceptable service ratio or response times for parks.

Proposed Project
Less Than Significant Impact. The Proposed Project would not generate demand for recreational facilities or parks and would not require the need for construction of new or modification to the existing parks and recreational facilities. As noted above, the Proposed Project has been designed to maintain/facilitate access to the OC Parks Gypsum Canyon Wilderness trailhead. Provision of this access is consistent with the planned recreational trail outlined in EIR No. 331 and the conclusions of EIR No. 331 remain valid.

Would the project conflict with any applicable plan, policy or regulation of an agency with jurisdiction over the project adopted for the purpose of avoiding or mitigating an environmental effect?
Approved Project
Less Than Significant Impact. The Table 3.M below addresses the consistency of the Approved Project with the relevant goals and policies outlined in the City of Anaheim General Plan and SCAG Regional Comprehensive Plan (RCP). As identified in Table 3.M, the findings in EIR No. 331 would remain consistent with the relevant goals and policies related to parks and recreation.

Proposed Project
Less Than Significant Impact. The Proposed project is not removing any public recreational facilities that were identified in the approved Mountain Park Specific Plan. The Proposed Project’s 24-foot- wide Gypsum Canyon Wilderness Trailhead access road would support local and regional recreational planning policies by providing improved and continued access to this publicly owned recreational facility. Thus, the Proposed Project would not conflict with any applicable plan, policy, or regulation of any agency with jurisdiction over the project. The Proposed Project would not impact recreational uses and the findings of EIR No. 331 remain valid.

3.13.3 Cumulative Recreation Impacts
Approved Project
Less Than Cumulatively Considerable Impact. The cumulative study area for parks and recreation would be the City, including residents who utilize public recreational facilities. EIR No. 331 anticipated the increase in population resulting from the residential uses included under the Approved Project would result in an increased demand for local and regional recreational facilities.

However, as indicated in the impact analysis in EIR No. 331 as summarized above, the Approved Project also included on-site recreational facilities, thereby reducing the level of use of off-site local and regional recreation facilities. In addition, the Approved Project would improve the local trail network. As such, the Approved Project’s cumulative contribution to the physical impact on local and regional recreational facilities was not found to be significant. 3-163

Goal 9.1: Reduce single occupancy vehicle trips.
• Policy 4: Encourage bicycle and pedestrian travel by
improving the City’s trail and bikeway master plan and by providing convenient links between the trail system and desired destinations.

The Mountain Park Specific Plan project includes provision of both public trails and Class II on-road bikeways that would interconnect with existing off-site trail and bikeway systems. These facilities would allow bicycle and pedestrian travel throughout the project site and to off-site locations.

The project would be consistent with Goal 9.1 and Policy 4.

Goal 18:1: Provide sufficient indoor and outdoor park,
recreation and community service opportunities for existing and future residents and employees.
• Policy 1: Maintain a Citywide standard of at least two acres of parkland per thousand residents.
• Policy 2: Locate neighborhood parks within walking
distance of the surrounding neighborhood.
• Policy 3: Locate parks adjacent to schools, where
possible, to facilitate joint-use of publicly owned land and facilities.
• Policy 4: Design new facilities to serve as many
compatible, overlapping uses as possible such as
baseball/softball outfields also serving as soccer fields.

A total of 24.75 acres of public and private park facilities would be provided on the project site. The 15-acre public community park, with improvements, would meet the
citywide standard of two acres of parkland per thousand residents (representing a requirement for the project to provide 16.5 acres of park land or pay in-lieu fees) and would be available for use by future project residents as well as residents from surrounding areas. Due to their
proximity to existing and proposed residential uses,
residents would be able to walk to the community park site as well as proposed private recreational facilities within the project site. The project would be consistent with Goal 18.1 and Policies 1 and 2.
• Policy 6: Continue to provide a variety of park types and facilities, especially dedicated sports fields and practice fields that serve the diverse needs of Anaheim’s
neighborhoods.

The proposed community park is adjacent to the proposed school site and would allow for joint use of these public facilities, consistent with Policy 3. Conceptual site planning for the project site has taken into consideration this joint- use function to ensure that all of the area is used efficiently facilitating joint use. Overlapping uses would also be
accommodated, consistent with Policy 4.

Proposed amenities at the community park and private
parks within the project would support a variety of passive and active recreation needs. As previously noted, the
community park would provide facilities for various types of sports consistent with Policy 6,
Goal 22:1: Complete the Riding and Hiking Trails Master Plan by closing gaps in the existing network of trails. • Policy 1: Obtain dedication, acquisition and development of trails rights-of-way to City standards in order to
complete the trail network shown on the Green Plan and
Riding and Hiking Trails Master Plan.
• Policy 3: Link the trail system, where feasible, with existing or future parks and other appropriate public
areas.
• Policy 4: Link the trail system with Orange and Riverside Counties’ regional trails and with those in the Cleveland National Forest and Chino Hills State Park.
• Policy 5: Expand the trail system by incorporating trails and trail stops within public and quasi-public rights of way.

The project includes implementation of a segment of the Gypsum Creek Regional Riding and Hiking Trails that would link the Featherly Regional Park, Santa Ana River, and
Gypsum Canyon trails together. These linkages would
provide access to off-site recreational uses such as
Featherly Regional Park and Chino Hills State Park. The project would be consistent with Goal 22.1 and Policies 1, 3, and 4.

The proposed trail staging area near the intersection of Gypsum Canyon Road and Santa Ana Canyon Road would
provide for additional direct access to the County’s Regional Riding and Hiking Trail system. The project would be
consistent with Goal 22.1 and Policy 5.

The Proposed Project would include private trails interior to the project’s Development Areas. The Homeowner’s

• Policy 1: Provide safe, direct and continuous bicycle routes for commuter and recreational cyclists.
• Policy 6: Implement a bikeway system with linkages to routes in neighboring jurisdictions and regional bicycle routes.

The project includes development of several
interconnecting Class II bikeways that would also provide linkages to existing and proposed off-site bikeways.

Additionally, the location of Class II bikeways within
proposed street rights-of-way would serve to provide direct routes for both commuter and recreational cyclists. The project would be consistent with Goal 7.1, Policies 1 and 6.

County of Orange General Plan Recreation Element
Goal 1: Provide a useful, enjoyable, safe, and efficient public regional riding and hiking trail system to meet the needs and desires of the citizens of the entire County.

Goal 2: Create trail linkages between open space and
recreational facilities, between community, municipal, state and federal trail systems, and between the trail systems of surrounding counties.
• Objective 1: Implement and maintain a public regional riding and hiking trails system as depicted conceptually on the Trails Map.
• Objective 3: Adopt official design standards for
constructing and maintaining regional trails including
signage and staging areas.
• Objective 5: Develop a regional trail system to meet the recreational needs of equestrians, pedestrians (walkers, hikers, and joggers) and mountain bikers.
• Objective 9: Coordinate with other local jurisdictions and state and federal agencies regarding trails development and maintenance.

The Proposed Project includes implementation of the
portion of the public Gypsum Creek Trail extending south from the Santa Ana River Trail in Yorba Linda, to the TNC ACE boundary within the project site. This trail would
provide a link between the proposed trail staging area in Development Area 6 and the open space within the project site. The improved trail segment would connect with the existing unimproved dirt road which extends through the site southwest to a crossing under SR-241 and further to the west.

The public trail would be designed and constructed in
compliance with the County’s standards for regional riding and hiking trails and would be implemented by the property owner/developer, in coordination with the County of
Orange and City of Anaheim. The trail would be available to the public; however, the unimproved portion of the trail is within the TNC ACE and access would be subject to an
approved public access plan.

Proposed Project
Less Than Cumulatively Considerable Impact. As with the Approved Project, the cumulative study area for parks and recreation would be the City, including residents who utilize public recreational facilities. As described in the analysis presented in this section, the Proposed Project would not include any residential uses and therefore would not increase demand for recreational facilities.

Additionally, the Proposed Project proposes a 24-foot-wide access road and an entry gate to improve and provide continued access to the existing Gypsum Canyon Wilderness Area trailhead, similar to the proposed public trail under the Approved Project. Given that the Proposed Project does not increase demand for recreational resources and provides for improved and continued access to the regional recreational facilities in the Gypsum Canyon Wilderness Area, no cumulative recreational impacts are anticipated and the findings of EIR No. 331 remain valid.

3.13.4 Findings Related to Recreation

3.13.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR Based on the foregoing analysis and information, there is no evidence that the Proposed Project requires a major change to EIR No. 331. The Proposed Project would not result in new significant environmental impacts related to recreation, and there would not be a substantial increase in the severity of impacts described in EIR No. 331.

3.13.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR The currently proposed changes to the Specific Plan Area would greatly reduce the originally identified impacts outlined in EIR No. 331. The greatly reduced impacts would not require revisions to the analysis in EIR No. 331. There is no information in the record or otherwise available that indicates that there are substantial changes in circumstances pertaining to recreation that would require major changes to EIR No. 331.

3.13.4.3 No New Information Showing Greater Significant Effects than the Certified EIR This Addendum has analyzed all available relevant information to determine whether there is new information that was not available at the time EIR No. 331 was certified that could indicate that a new significant effect not reported in that document may occur. Based on the information and analyses above, there is no substantial new information indicating that there would be a new significant impact related to recreation requiring major revisions to EIR No. 331.

3.13.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR There is no new information, mitigation, or alternatives to the Proposed Project that would substantially reduce one or more significant impacts pertaining to recreation identified and considered in EIR No. 331.

3.13.5 Standard Conditions and Mitigation Measures
No Mitigation Measures were identified in EIR No. 331 pertaining to recreation. Standard Condition 13-1 was identified as applicable to the Approved Project, but since it is concerned with DA 3, it would not apply to the Proposed Project and is therefore not included.

3.14 CULTURAL RESOURCES

3.14.1 Existing Environmental Setting
According to EIR No. 331, a Cultural Resource Survey and Assessment (2002) was prepared for the MPSP area and centered on Gypsum Canyon and several tributary canyons which occur within the Santa Ana Mountains. This area forms part of the northern end of the Peninsular Range geologic province and due to the steep topography in the area, portions of the project site would have been uninhabitable. There are various Coastal sage scrub and lower chaparral habitats in the area that would have provided many important resources to local prehistoric habitants. Additionally, thick vegetation occurs along north-facing slopes and in narrow canyon bottoms and sparser vegetation occurs along ridge tops and canyon bottoms, which may have been occupied by humans. The 2002 record search and literature review indicate that several fossil localities have been recorded in the area, and that the area is underlain by several fossiliferous geologic formations that have low to high paleontological sensitivity. No cultural or paleontological resources were identified within the MPSP as part of the 2002 Cultural Resources Survey and Assessment.

A Cultural Resources Study was prepared in 2024 (LSA, 2024) to update the prior assessment and identify the potential to encounter any new cultural resources within the project site. A field survey (conducted December 9, 2023) of the project site resulted in no cultural resources being discovered.

Additionally, a record search (completed April 15, 2024) was conducted for the update and covered a 0.5-mile radius of the project site and did not identify recorded cultural resources within or adjacent to the project site. There have been five cultural resources recorded within 0.5-mile of the project site. Neither the 2002 nor 2024 studies identified any cultural resources within the project site ).

3.14.2 Comparison of Impacts for the Approved Project and the Proposed Project.

EIR No. 311 indicated that the previous Cultural Resource Survey and Assessment (2002) included a consultation with Native Americans regarding the Approved Project resulted in the incorporation of MMs 14-1 and 14-2 into Draft EIR No. 331. Coordination with the California Cultural Resource Preservation Alliance (CCRPA), an alliance of Native Americans, archaeologists, cultural resource management professionals and individuals working together to identify and preserve important archaeological and cultural sites, was conducted as part of the public review of Draft EIR No. 331. As part of this coordination and in response to the CCRPA comments on the Draft EIR, MM 14-1 was modified in EIR No. 331 to require that a Native American monitor be retained to monitor construction activities.

For the Proposed Project, the Native American Heritage Commission (NAHC) responded to a Sacred Lands File search request on January 8, 2024, and letters were sent to the respective Native American Tribes on March 12, 2024. The City has initiated consultation with the tribes designed in the NAHC response and the consultation is ongoing.

Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5 of the CEQA Guidelines? 3-167

A N A H E I M, C A L I F O R N I A

Approved Project
Less Than Significant Impact with Mitigation. EIR No. 331 indicated that no archaeological sites, as defined in resource pursuant to Section 15064.5 of the State CEQA Guidelines, have been identified within the project site, however, such resources have the potential to exist in the immediate vicinity of the study area for the Approved Project. EIR No. 331 did identify the potential for subsurface cultural deposits during grading activities, which would be considered a potentially significant impact. Mitigation Measures 14-1 and 14-2 were incorporated into EIR No. 331 and with implementation of these measures, impacts to cultural resources were reduced to less than significant.

Proposed Project
Less Than Significant Impact with Mitigation. The Proposed Project would involve substantial grading within DA 5 to construct the pads for the proposed cemeteries and on-site roads and infrastructure similar to the proposed development anticipated in the Approved Project, including areas previously disturbed and filled by mining activities and some alluvial deposits (as described in Section 3.3 above). The 2024 Cultural Resource Study includes an updated records search and field survey of the project, and no cultural or tribal resources were identified within the project site. As there were no historical resources identified within the previous EIR No. 331 nor with the 2024 Study, with implementation of Mitigation Measures 14-1, requiring archaeological monitoring during grading activities, the Proposed Project would not cause a substantial adverse change in the significance of an archaeological resource.

During cemetery operations, preparation of burial sites would occur exclusively within previously excavated material, which has a low sensitivity for cultural resources. Prior mining operations removed substantial amounts of material, dramatically changing the topography on-site.

Additionally, the anticipated excavation for mass grading of the project site and installation of infrastructure would further modify the current on-site topography substantially. Mass grading activities during construction would include cuts ranging from 20 to 147 feet and fills ranging from 30 to 102 (as noted in Section 3.3). Between the prior mining activities and the proposed mass grading, the conditions on the entire site would be substantially altered and the potential for encountering in-situ or disturbed archaeological or tribal resources during operation of the cemeteries is considered negligible. Monitoring during excavation for burial sites would not be required since mass grading of the upper and lower pads during Project construction would be subject to Mitigation Measure 14-1, which would adequately address the possibility of encountering unknown archaeological and tribal cultural resources within the soil disturbed during these activities. Therefore, the conclusions of EIR No. 331 remain valid.

Would the project cause substantial adverse change in the significance of a historical resource as identified in §15064.5 of the CEQA Guidelines?
Approved Project
Less Than Significant Impact with Mitigation. EIR No. 331 indicated that no historical resources, as defined in Section 15064.5 of the CEQA Guidelines, have been identified within the project site, however, such resources exist in the immediate vicinity of the study area for the Approved Project.

EIR No. 331 did identify the potential for unknown subsurface cultural deposits to be discovered during grading activities, which would be considered a potentially significant impact. Mitigation Measures 14-1 and 14-2 were incorporated into EIR No. 331 and with implementation of these measures, potential impacts to cultural resources were reduced to less than significant.

Proposed Project
Less Than Significant Impact with Mitigation. The Proposed Project would involve substantial grading within DA 5 to construct the pads for the proposed cemeteries and on-site roads and infrastructure similar to the proposed development anticipated in the Approved Project. As there were no historical resources identified within the previous EIR No. 331 nor with the 2024 Study. As mentioned previously, a record search (completed April 15, 2024) was conducted for the update and covered a 0.5 mile radius for the project site and resulted no recorded cultural resources within or adjacent to the project site. There have been five cultural resources recorded within 0.5 mile of the project site. With implementation of Mitigation Measures 14-1 and 14-2, there would be no substantial adverse change to any historical resources through the Proposed Project, and the conclusions of EIR No. 331 remain valid.

Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
Approved Project
Less Than Significant With Mitigation Incorporated. As stated earlier, no paleontological resources were identified within the Approved Project study area, however, the MPSP area, including DA 5, is known to contain several fossil-bearing geologic formations. In particular, the north-central project site area contains Sespe, Santiago, and Topanga Formations which have moderate to high potential to contain paleontological resources. As such, Mitigation Measure 14-3 was identified in EIR No. 331 to reduce potential impacts to paleontological resources to less than significant.

Proposed Project
Less Than Significant With Mitigation Incorporated. Similar to the Approved Project, the Proposed Project area is located on the north-central portion of the project site which has the potential to contain fossil-bearing geologic formations (Sespe, Santiago, and Topanga). Since the existing conditions of the Proposed Project area have not changed since the Approved Project, there is the potential to encounter paleontological resourced during grading activities within the project site and implementation of Mitigation Measure 14-3 applicable to the Proposed Project. As there are no known paleontological resources identified within the project site and with implementation of MM 14-3, potential impacts to paleontological resources would be same as identified for the Approved Project, and the conclusions of EIR No. 331 remain valid. 3-169

Would the project disturb any human remains, including those interred outside of formal cemeteries?
Approved Project
Less Than Significant With Mitigation Incorporated. As described above, no cultural resources, including formal cemeteries were identified in EIR No. 331. However, this ultimately does not preclude the possibility that individual burials may be discovered during grading or excavation activities. As such, Mitigation Measures 14-1 and 14-2, were identified to ensure a less than significant impact would occur to human remains.

Proposed Project
Less Than Significant With Mitigation Incorporated. As described above, no cultural resources were identified in EIR No. 331 or the 2024 Study for the project site. Historic-period aerial photographs of the project site were reviewed and indicate that, between 1952 and 1959, rock-quarrying operations appeared at the northwest corner of the project site. By 1980, these operations expanded to cover more of the project site and managed to cover a wider footprint of the project area by 2002. By 2005 and 2009, quarry operations appeared to have ceased during that period.

Based on the previous history of the project site, there are no known formal cemeteries within the Proposed Project area; however, even with the project’s level of disturbance there is still some minor potential for human remains to be discovered during grading or excavation activities to construct the Proposed Project. As such, MM 14-2 from EIR No. 331 would remain applicable to ensure a less than significant impact would occur to human remains. As the existing conditions of the project study area have not changed and with implementation of MM 14-2, the conclusions from EIR No. 331 remain valid.

Would the project conflict with any applicable plan, policy or regulation of an agency with jurisdiction over the project adopted for the purpose of avoiding or mitigating an environmental effect?
Approved Project
Less Than Significant Impact with Mitigation Incorporated. As described in EIR No. 331, there are no plans, policies, or regulations of the City of Anaheim related to the protection of cultural resources within the MPSP area. The project would remain consistent with the Southern California Association of Government’s Policy 3.21 related to the preservation and protection of recorded and unrecorded cultural resources and archaeological sites. The Approved Project would not result in significant impacts to any recorded resources and Mitigation Measures 14-1 through 14-3 would be implemented to ensure that any unknown and previously undocumented cultural resources are avoided.

Proposed Project
Less Than Significant With Mitigation Incorporated. Similar to the Approved Project, there are no plans, policies, or regulations of the City of Anaheim related to the protection of cultural resources on the project site and implementation of Mitigation Measures 14-1 and 14-2 would ensure that potential impacts to unknown cultural resources are addressed. The Proposed Project would not

result in significant impacts to any recorded resources and mitigation measures 14-1 through 14-3 from EIR No. 331 would remain applicable to ensure than any unknown and previously undocumented cultural resources are avoided and the conclusions of EIR No. 331 remain valid.

3.14.3 Cumulative Cultural Resources Impacts
Approved Project
Less Than Cumulatively Considerable Impact with Mitigation Incorporated. As analyzed in EIR No. 331, there would be no impact to any known cultural or paleontological resources. The project’s cumulative development in conjunction with past, present, and probably future projects would result in the disturbance of cultural resource sites throughout the region, the City and County would require mitigation of impacts to these resources. This includes the collection and preservation of artifacts, which may contribute to local and regional history and prehistory. As a result, the Approved Project would not have a significant cumulative impact on archaeological and paleontological resources or result in a significant cumulative loss of regional history or prehistory with the implementation of MM 14-1 through 14-3.

Proposed Project
Less Than Cumulatively Considerable Impact. As mentioned previously, the existing conditions in terms of the project site have not been changed since EIR No. 331 has been documented. The recent Cultural Study (2023) record search results and field survey indicated confirmed that no cultural resources were identified within the project site and that presence of cultural resources occurring the project site is deemed to be negligible. However, the Proposed Project has potential to result in disturbance of cultural resources throughout the Proposed Project area, and the City and County would require mitigation of impacts to these resources. Overall, the previous findings in EIR No. 331 remain valid, and the Proposed Project would not have a significant cumulative impact on archaeological and paleontological resources or result in a significant cumulative loss of regional history or prehistory with the implementation of MM 14-1 through 14-3.

3.14.4 Findings Related to Cultural Resources

3.14.4.1 No New Significant Effects Requiring Major Revisions to the Certified EIR Based on the foregoing analysis and information, there is no evidence that the Proposed Project requires a major change to EIR No. 331. The Proposed Project would not result in new significant environmental impacts related to cultural resources, and there would not be a substantial increase in the severity of impacts described in EIR No. 331.

3.14.4.2 No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR There are no substantial changes in circumstances requiring major revisions to EIR No. 331 as the Proposed Project would result in less overall development and construction impacts due to the nature of cemetery facilities. There is no information in the record or otherwise available that indicates a substantial change in circumstances pertaining to cultural resources, therefore, the findings in EIR No. 331 remain valid.

3.14.4.3 No New Information Showing Greater Significant Effects than the Certified EIR This Addendum has analyzed all available relevant information to determine whether there is new information that was not available at the time of EIR No. 331, indicating that a new significant effect not reported in that document may occur. Based on the information and analyses above, there is no substantial new information indicating that there would be a new significant impact related to cultural resources requiring major revisions to EIR No. 331.

3.14.4.4 No New Information Showing the Ability to Reduce Significant Effects in the Certified EIR There is no new information, mitigation, or alternatives to the Proposed Project that would substantially reduce one or more significant impacts pertaining to cultural resources identified and considered in EIR No. 331.

3.14.5 Standard Conditions and Mitigation Measures
While no Standard Conditions were identified under the Approved Project, Mitigation Measures (MM) 14-1 through 14-3 were identified to reduce potential impacts under the Approved Project to a less than significant level. MM 14-1 through 14-3 would remain applicable to the Proposed Project.

MM 14-1 Prior to the issuance approval of a grading plan or issuance of a building permit, whichever occurs first, the property owner/developer shall retain a County-certified archaeologist (project archaeologist) and submit written confirmation of this to the Department of Public Works/Planning and Building Division. The project archaeologist shall observe grading activities during project construction and recover, catalogue, analyze, and report archaeological resources as necessary in the previously undeveloped of-way) portions of the development area. The project archaeologist shall be present at the pre-grade conference. The project archaeologist shall submit to the Planning Department, and Department of Public Works, Development Service Division, a written plan with procedures for archaeological resource monitoring. For work within Caltrans right-of-way the plan shall be submitted for review by Caltrans Cultural Resources staff. This plan shall include procedures for temporarily halting or redirecting work to permit the sampling, identification and evaluation of the resources as appropriate, and a requirement that a Native American monitor retained by the property owner/developer be present during any required excavation. If the archaeological resources are found to be significant, the project archaeologist shall determine appropriate actions-in cooperation with the City of Anaheim or Caltrans, if within Caltrans right-of-way-for exploration and/or data recovery to adequately recover the scientifically significant information from or about the archeological resource.

The project archaeologists shall prepare any excavated material to the point of identification. Following the completion of grading associated with project construction, the archaeologists shall prepare a report detailing the results of the monitoring program to be presented to the City of Anaheim Planning Department.

The report shall follow guidelines of the California Office of Historic Preservation

(1990). Excavated finds shall be accessioned into a qualified scientific institution that meets, or exceeds, the requirements of 36CFR79.

MM 14-2 If human remains are encountered during the conduct of ground-disturbing activities, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition of the materials pursuant to Public Resources Code Section 5097.98.

The County Coroner must be notified of the find immediately. If the remains are determined to be prehistoric, the Coroner would notify the Native American Heritage Commission (NAHC). The NAHC would determine and notify a Most Likely Descendent (MLD). The MLD may inspect the site of the discovery with the permission of the property owner/developer or his/her authorized representative.

The descendent must complete the inspection within 24 hours of notification by the NAHC. The MLD may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials.

MM 14-3 Prior to issuance of the first grading permit, the property owner/developer shall submit a monitoring plan, prepared by an Orange County certified paleontologist to the Department of Public Works, Development Services Division/Planning & Building Department that ensures that the following actions are implemented:
a. The area west of Gypsum Canyon is comprised almost entirely of the Topanga Formation (high paleontological sensitivity) and contains all of the heretofore recognized surface occurrences of fossils on the project site. The north-central portion of the project site is comprised chiefly of the interbedded undifferentiated Vaqueros and Sespe Formations (moderate to high paleontological sensitivity) and smaller elements of the Sespe, Santiago, and Topanga Formations (all high paleontological sensitivity). Paleontological monitoring in the western and north-central areas of the project site shall be conducted on a full-time basis and shall be identified as such in the monitoring plan. It shall be the responsibility of the project paleontologist to show, to the satisfaction of the City, the recommended limits of full-time monitoring on the tentative tract or parcel map level grading plans, when available. Because of the potential for identifying microfossils or small fragments of macrofossils, periodic screening of sediments from cuts in these formations shall be carried out by the project paleontologist. Such material may be removed in bulk and screened off- site to minimize interference with grading operations.
b. The Holz Shale, Schulz Ranch Member of the Williams Formation, the Silverado Formation, Santiago Formation, and the Sespe Formation, exposed primary east of Gypsum Canyon, shall be monitored as determined necessary by the project paleontologist during grading operations. Recommended hours for monitoring activities shall be established by the project paleontologist and shall be outlined in the monitoring plan. It shall be the responsibility of the project paleontologist to demonstrate, to the satisfaction of the City, the appropriate level of monitoring necessary based on the tentative tract or parcel map level grading 3-173

plans, when available. Because of the potential for identifying microfossils or small fragments of macrofossils, periodic screening of sands from cuts in these units shall be done by the project paleontologist monitor. Such material may be removed in bulk and screened off-site to minimized interference with grading operations.
c. Any paleontological work at the site shall be conducted under the direction of a County of Orange Certified paleontologist (project paleontologist). d. If a fossil discovery occurs during grading operations when the project paleontologist is not present, grading shall be diverted around the area until the monitor can survey the area, and or Caltrans Cultural resources staff can inspect the site, if the resources are to be found within Caltrans right-of-way. e. Any fossils recovered during the development, along with their contextual stratigraphic data, shall be donated to the County of Orange, or other appropriate institution with an educational and research interest in the materials. A final report detailing findings and disposition of specimens shall be prepared by the project paleontologist and submitted to the City of Anaheim Planning & Building Department upon completion of grading.

MITIGATION MONITORING AND REPORTING PROGRAM NO. 137

MITIGATION MONITORING PROGRAM NO. 137

FOR THE MOUNTAIN PARK
SPECIFIC PLAN NO. 90-4, AMENDMENT NO. 1
CEQA Action: Environmental Impact Report No. 331
Project Description: The Mountain Park Specific Plan (SP 90-4) currently allows for the development of 7,966 residential units, commercial uses, interim sand and gravel mineral extraction, schools, parks and open space. The project applicant, The Irvine Community Development Company, proposes to amend the Mountain Park Specific Plan to reduce the number of residential units to a maximum of 2,500 and to provide for the following: a City fire station; a school site and adjacent public community park; public and private recreational facilities, including riding and hiking trails and a trail staging area; an interpretive center and store concession; and roadways and utilities necessary to serve the proposed development. Approximately 2, 163 acres of open space would be preserved as part of the project. Additionally, the proposed project includes the construction of the State Route 241 (SR-241 )/Weir Canyon Road interchange, and a bridge over SR-241 connecting development areas east and west of SR-241.

The primary actions associated with the project include a proposed amendment to the Mountain Park Specific Plan to implement the adopted City of Anaheim General Plan, and a proposed amendment to the City of Anaheim Zoning Code to incorporate revised Zoning and Development Standards for the Mountain Park Specific Plan area. Also proposed is an amendment to the General Plan Safety Element, Fire Protection Areas (Figure S-5) to remove proposed development areas from the Very High Fire Hazard Severity Zone designation.

Project Location: The proposed project site is located generally in Gypsum Canyon, south of the Riverside (SR-91) Freeway, in Orange County, California.

The majority of the project site is in the jurisdiction of the City of Anaheim; however, open space areas in the southern- and eastern-most portions of the project site are in unincorporated County of Orange jurisdiction in the City of Anaheim's sphere-of-influence. SR-91 is immediately north of the project site, and the SR-241 bisects the site into eastern and western segments.

Terms and Definitions:

1. Property Owner/Developer - Any owner or developer of real property within the boundaries of the Mountain Park Specific Plan area.

2. Environmental Equivalent/Timing - Any Mitigation Measure and timing thereof, subject to the approval of the City of Anaheim, which will have the same or superior result and will have the same or superior effect on the environment. The Planning Department, in conjunction with any appropriate agencies or City departments, shall determine the adequacy of any proposed "environmental equivalent/timing" and, if determined necessary, may refer said determination to the Planning Commission. Any cost associated with the information required in order to make a determination of environmental equivalency/timing shall be borne by the property owner/developer. Staff time for reviews will be charged on a time and materials basis at the rate in the City of Anaheim's adopted fee schedule.

3. Timing - This is the point where a mitigation measure must be monitored for compliance. In the case where multiple action items are indicated, it is the first point where compliance associated with the mitigation measure must be monitored. Once the initial action item has been complied with, no additional monitoring pursuant to the Mitigation Monitoring Program will occur, as routine City practices and procedures will ensure that the intent of the Mitigation Monitoring Program No. 137
- .... - - - - a; - - - ...... -- --- - -
measure has been complied with. For example, if the timing is "to be shown on approved building plans" subsequent to issuance of the building permit consistent with the approved plans will be final building and zoning inspections pursuant to the building permit to ensure compliance.

4. Responsibility of Monitoring - Shall mean that compliance with the subject mitigation measure(s) shall be reviewed and determined adequate by all departments listed for each mitigation measure.

5. Ongoing Mitigation Measures - The mitigation measures that are designated to occur on an ongoing basis as part of this mitigation monitoring program will be monitored in the form of an annual letter from the property owner/developer in January of each year stating how compliance with the subject measures(s) has been achieved. When compliance with a measure has been demonstrated for a period of one year, monitoring of the measure will be deemed to be satisfied and no further monitoring will occur. For measures that are to be monitored "Ongoing During Construction", the annual letter will review those measures only while construction is occurring; monitoring will be discontinued after construction is completed.

The Mountain Park Specific Plan includes a Proposed Drainage System Plan (refer to Exhibit 3-9 of the Draft EIR included in Attachment A). Prior to approval of the first mass grading plan, the property owner/developer shall submit a Drainage and Runoff Management Plan (RMP) to the Department of Public Works for review and approval. The RMP shall demonstrate substantial conformance with the Proposed Drainage System included in the Mountain Park Specific Plan. The Drainage and Runoff Management Plan shall include the approximate timing for construction of the following drainage facilities:
a. Gypsum Canyon Road/SR-91 Box Culvert Modification: A 1,500 linear foot culvert modification will be constructed at the downstream end of Gypsum Canyon to address existing deficiencies and accommodate proposed peak flows from the project site. The proposed storm drain improvement plan will extend the Gypsum Canyon Road/SR-91 box culvert inlet structure approximately 1,500 feet upstream following the existing alignment of the Gypsum Canyon Creek. At this location, the proposed Gypsum Canyon Road will be designed to serve as an impoundment to retain storm water runoff up to approximately 17 feet, which produces sufficient hydraulic head to convey 5,500 cfs through the culvert into Featherly Park. The elevation difference between the flow line of the culvert inlet and the top of the road is expected to be approximately 20 feet, allowing for a freeboard of three feet. The extension of the culvert upstream, with the described design modifications to the inlet control, will prevent flooding onto Gypsum Canyon Road during large storm events.

The proposed modification of the culvert will improve the flood control design capacity of the culvert from a 10-year storm event to a 100-year storm event. A confirmation of the structural integrity and design calculations of the existing culvert structure shall be completed prior to final design of the new box culvert extension.
b. West Drainage Area Storm Drain Improvement: Minor storm drain improvements to an existing undersized 36-inch reinforced concrete pipe (RCP) that collects off-site runoff from the undisturbed slopes draining into The Summit will be upsized to the capacity of a 54-inch RCP for proper conveyance of the project flows into the existing 66-inch RCP. c. SR-91/Gypsum Canyon Road Storm Drain Improvement: A minor storm drain improvement will be implemented for the 4-acre sub-area that used to drain into the existing culvert inlet but will not adequately drain after the culvert extension. The improvement will consist of a riser tower and a RCP (size to be determined) to collect the flows and connect directly into the triple box culvert at the approximate location of the existing culvert inlet.

Featherly Regional Park Channel Improvements: The improvements to the box culvert outlet for energy dissipation of flood flows will include a concrete apron followed by riprap to reduce velocities down to the 10 to 12 feet per second (fps) range. Riprap will also be added to the embankments beyond the concrete apron. To provide additional stabilization of the channel downstream, flow velocities will be decreased to the range of 10 to 12 fps where turf-reinforced mesh blankets will be used, and vegetation re-established along the channel bottom and embankments. Turf-reinforced blankets (or equivalent alternatives) will continue along the embankment up to a maximum of 340 feet beyond the riprap leading up to the existing road crossing. Prior to approval of a grading permit, the property owner/developer shall provide evidence to the Department of Public Works that the design and construction of these improvements have been approved by the County of Orange Harbors, Beaches and Parks Department.

Outlet Points to Natural Channels: Energy dissipation/velocity reduction devices will be employed to ensure flows are released at non- erosive velocities. Such devices may include: riprap, geotextiles, granule filters, fills, grade control structures and/or check dams, or equivalent measures.
f. Vegetated f/oodwa/1 for Community Center: As part of final design, a vegetated floodwall would be incorporated into the portion of the slope downstream of the community center as necessary to satisfy flood control requirements.

• A monitoring biologist, acceptable to USFWS/CDFG will be on-site during any clearing of CSS. The landowner or relevant public agency/ utility will advise USFWS/CDFG at least seven (7) calendar days [and preferably fourteen (14) calendar days] prior to the clearing of any habitat occupied by Identified Species to allow USFWS/CDFG to work with the monitoring biologist in connection with bird flushing/capture activities. The monitoring biologist will flush Identified Species (avian or other mobile Identified Species) from occupied habitat areas immediately prior to brush-clearing and earth-moving activities. If birds cannot be flushed, they will be captured in mi$t nets, if feasible, and relocated to areas of the site to be protected or to the NCCP/HCP Reserve System. It will be the responsibility of the monitoring biologist to assure that Identified bird species will not be directly impacted by brush-clearing and earth-moving equipment in a manner that also allows for construction activities on a timely basis.
• Following the completion of initial grading/earth movement activities, all areas of CSS habitat to be avoided by construction equipment and personnel will be marked with temporary fencing and other appropriate markers clearly visible to construction personnel. No construction access, parking, or storage of equipment or materials will be permitted within such marked areas.
• In areas bordering the NCCP Reserve System or Special Linkage/Special Management areas containing significant CSS identified in the NCCP/HCP for protection, vehicle transportation routes between cut-and-fill locations will be restricted to a minimum number during construction consistent with project construction requirements. Waste dirt or rubble will not be deposited on adjacent CSS identified in the NCCP/HCP for protection. Pre-construction meetings involving the monitoring biologist, construction supervisors, and equipment operators will be conducted and documented to ensure maximum practicable adherence to these measures.

Create (establish), restore, or enhance wetland/riparian habitats on-site to the maximum extent practicable to minimize the on-site loss of ACOE and CDFG jurisdictional acreage and function, and provide off-site mitigation for the remainder of the impacts;
To implement, to the extent practicable, off-site mitigation in the Santa Ana River watershed, as close to the study area as possible or otherwise at a key ecological site;
• To return jurisdictional habitats that are temporarily disturbed during construction to pre-construction conditions; and,
• To ensure that adjacent non-jurisdictional habitats are protected.

The preferred on-site mitigation approach shall be approved by the ACOE, CDFG and RWQCB during the permitting process. One possible component of the on-site mitigation, to address the impacts of the box extension on the already disturbed Gypsum Canyon Creek channel, could include a rebuilt creek as a low-flow riparian corridor through the canyon mouth area.

Conceptually, the box extension shall act as a high-flow by-pass that efficiently conveys the more intense and destructive flood flows. The riparian corridor shall extend upstream to the road crossing of Gypsum Canyon Creek. The riparian corridor shall consist of a riverine channel flanked by planted embankments. The riverine channel would be soft bottom and the riparian vegetated floor would be nurtured by low an.d seasonal run-off diverted into it from a channel split from the new box culvert opening. This "splitter" shall consist of a junction opening that becomes a tunnel that would accommodate storm flows as well as wildlife movement under the road crossing to the riparian corridor.

This would ensure that no active nests would be disturbed and that removal could proceed rapidly. If vegetation removal activities shall occur during the nesting season (February 15 to July 15), all suitable habitat shall be thoroughly surveyed for the presence of nesting birds by a qualified biologist prior to removal. If any active nests are detected, the area shall be flagged, along with a minimum 50-foot buffer (buffer may range between 50 and 300 feet as determined by the monitoring biologist), and shall be avoided until the nesting cycle is complete or it is determined by the monitoring biologist that the nest has failed." In addition, a biologist shall be present on the site to monitor the vegetation removal to ensure that nests not detected during the initial survey are not disturbed. The project biological monitor shall provide written notification to the Planning Department that these requirements have been accomplished following completion of grading activities associated with each grading permit. 20 - -

Construction: Particulate Emission (PM10) Control
MM 8-1 Prior to approval of the first grading plan, the following requirements shall be incorporated into the Storm Water Pollution Prevention Program (SWPPP) and Erosion and Sedimentation Control Plan submitted for review and approval by the Department of Public Works. During construction of the proposed project, the property owner/development and its contractors shall be required to comply with regional rules, which shall assist in reducing short-term air pollutant emissions. SCAQMD Rule 402 requires that air pollutant emissions not be a nuisance off-site. SCAQMD Rule 403 requires that fugitive dust be controlled with the best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. Two options are presented in Rule 403: monitoring of particulate concentrations or active control.

Monitoring involves a sampling network around the project with no additional control measures unless specified concentrations are exceeded. The active control option does not require any monitoring, but requires that a list of measures be implemented starting with the first day of construction. 25 , , Respontlible for .

Rule 403 requires that "No person conducting active operations without utilizing the applicable best available control measures included in Table 1 of this Rule to minimize Fugitive dust emissions from each fugitive dust source type within the active operation." The measures from Table 1 of Rule 403 are provided in Attachment B. The applicable measures presented in Table 1 are required to be implemented by Rule 403.

Rule 403 requires that "Large Projects" implement additional measures. A Large Project is defined as "any active operations on property which contains 50 or more acres of disturbed surface area; or any earth-moving operation with a daily earth-moving or throughput volume of 3,850 cubic meters (5,000 cubic yards) or more three times during the most recent 365 day period.

Grading of the project would be considered a Large Project under Rule 403.

Therefore, the project shall be required to implement the applicable actions specified in Table 2 of the Rule. Table 2 from Rule 403 is presented in Attachment B. As a Large Operation, the project shall also be required to:
• Submit a fully executed Large Operation Notification (SCAQMD Form 403N) to the SCAQMD Executive Officer within 7 days of qualifying as a large operation;
• Include, as part of the notification, the name(s), address(es), and phone number(s) of the person(s) responsible for the submittal, and a description of the operation(s), including a map depiyting the location of the site;
• Maintain daily records to document the specific dust control actions taken, maintain such records for a period of not less than three years; and make such records available to the Executive Officer upon request. • Install and maintain project signage with project contact signage that meets the minimum standards of the Rule 403 Implementation Handbook, prior to initiating any earthmoving activities. • Identify a dust control supervisor that is employed by or contracted with the property owner/developer, is on the site or available on-site within 30 minutes during working hours, has the authority to expeditiously employ sufficient dust mitigation measures to ensure compliance with all Rule requirements, and has completed the AQMD Fugitive Dust Control Class and has been issued a valid Certificate of Completion for the class. • Notify the SCAQMD Executive Officer in writing within 30 days after the site no longer qualifies as a large operation.

Rule 403 also requires that the construction activities "shall not cause or allow PM10 levels exceed 50 micrograms per cubic meter when determined by simultaneous sampling, as the difference between upwind and down wind sample." Large Projects that cannot meet this performance standard are required to implement the applicable actions specified in Table 3 of Rule 403.

Table 3 from Rule 403 is presented in Attachment B. Rather than perform monitoring to determine conformance with the performance standard, which will not reduce PM10 emissions, the project shall implement all applicable measures presented in Rule 403 Table 3 regardless of conformance with the Rule 403 performance standard. This potentially results in a higher reduction of particulate emissions than if these measures were implemented only after being determined to be required by monitoring.

Further, Rule 403 requires that that the project shall not "allow track-out to extend 25 feet or more in cumulative length from the point of origin from an active operation." All track-out from an active operation is required to be removed at the conclusion of each workday or evening shift. Any active operation with a disturbed surface area of five or more acres or with a daily import or export of 100 cubic yards or more of bulk materials must utilize at least one of the measures listed in Attachment B at each vehicle egress from the site to a paved public road.

Construction: Construction Equipment Emission Control
MM 8-2 Prior to approval of grading plans, the property owner/developer shall include the following notes on the contractor specifications submitted for review and approval by the Department of Public Works: 'To reduce construction equipment emissions, the following measures shall be implemented when feasible.
• Use low emission mobile construction equipment. The property owner/ developer shall comply with CARB requirements for heavy construction equipment.
• Maintain construction equipment engines by keeping them tuned. • Use low sulfur fuel for stationary construction equipment. This is required by SCAQMD Rules 431.1 and 431.2.
• Utilize existing power sources (i.e., power poles) wh·en feasible. This measure would minimize the use of higher polluting gas or diesel generators.
• Configure construction parking to minimize traffic interference. • Minimize obstruction of through-traffic lanes. When feasible, construction should be planned so that lane closures on existing streets are kept to a minimum.
• Schedule construction operations affecting traffic for off-peak hours. 27 Department of Public

• Develop a traffic plan to m1rnm1ze traffic flow interference from construction activities (the plan may include advance public notice of routing, use of public transportation and satellite parking areas with a shuttle service.
• Use aqueous diesel fuel where feasible and reasonably commercially available.
• Use cooled exhaust gas recirculation (EGR) where feasible and reasonably commercially available.

Several of the mitigation measures listed above are advanced emission control technologies, which are currently not commercially available. For example, aqueous diesel fuel reduces NOX formation by reducing combustion temperatures, resulting in lower NOX emissions. According to the SCAQMD, the current availability of this fuel technology is limited, and it may not be available for use for the project. In addition, with EGR diesel engines, a small amount of hot exhaust gas is routed through a cooler and mixed with fresh air entering the engine. The exhaust gas helps reduce the temperature during combustion, which lowers the formation of thermal NOX.

EGR technology is in the development phase, and has not been fully commercialized. To the extent that the advanced emissions control technologies become reasonably commercially available, or are required by the CARB from grading contractors, then such advanced emissions control technologies shall be used.

MM 8-3 The property owner/developer shall reduce operation-related em1ss1ons through implementation of practices identified in SCAQMD's CEQA Handbook and the URBEMIS2002 model. SCAQMD's CEQA Handbook includes several measures that can be used to minimize emissions associated with residential projects. In addition, the URBEMIS2002 model identifies several measures, some of which overlap those in the CEQA Handbook. The following measures, based on these sources, shall be implemented by the property owner/developer and contractors, where feasible to reduce criteria pollutant emissions from stationary sources directly related to the project. Said measures shall be included on plans submitted for residential building permits:
• install solar or low-emission water heaters;
• use central water-heating systems;
• use built-in, energy-efficient appliances; and

If the archaeological resources are found to be significant, the project archaeologist shall determine appropriate actions-in cooperation with the City of Anaheim or Caltrans, if within Caltrans right-of-way-for exploration and/or data recovery to adequately recover the scientifically significant information from or about the archeological resource. The project archaeologists shall prepare any excavated material to the· point of identification. Following the completion of grading, the archaeologists shall prepare a report detailing the results of the monitoring program to be presented to the City of Anaheim Planning Department. The report shall follow guidelines of the California Office of Historic Preservation (1990).

Excavated finds shall be accessioned into a qualified scientific institution that meets, or exceeds, the requirements of 36CFR79.

If human remains are encountered during the conduct of ground-disturbing Planning Department activities, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition of the materials pursuant to Public Resources Code Section 5097.98. The County Coroner must be notified of the find immediately. If the remains are determined to be prehistoric, the Coroner would notify the Native American Heritage Commission (NAHC). The NAHC would determine and notify a Most Likely Descendent (MLD). The MLD may inspect the site of the discovery with the permission of the property owner/ 40 -

developer or his/her authorized representative. The descendent must complete the inspection within 24 hours of notification by the NAHC. The MLD may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials. -
Prior to issuance of the first grading permit, the property owner/developer Department of Public shall submit a monitoring plan, prepared by an Orange County certified Works, Development paleontologist to the Department of Public Works, Development Services Services Division Division that ensures that the following actions are implemented:
a. The area west of Gypsum Canyon is comprised almost entirely of the Topanga Formation (high paleontological sensitivity) and contains all of the heretofore recognized surface occurrences of fossils on the project site. The north-central portion of the project site is comprised chiefly of the interbedded undifferentiated Vaqueros and Sespe Formations (moderate to high paleontological sensitivity) and smaller elements of the Sespe, Santiago, and Topanga Formations (all high paleontological sensitivity). Paleontological monitoring in the western and north-central areas of the project site shall be conducted on a full-time basis and shall be identified as such in the monitoring plan. It shall be the responsibility of the project paleontologist to show, to the satisfaction of the City, the recommended limits of full-time monitoring on the tentative tract or parcel map level grading plans, when available. Because of the potential for identifying microfossils or small fragments of macrofossils, periodic screening of sediments from cuts in these formations shall be carried out by the project paleontologist. Such material may be removed in bulk and screened off-site to minimize interference with grading operations.
b. The Holz Shale, Schulz Ranch Member of the Williams Formation, the Silverado Formation, Santiago Formation, and the Sespe Formation, exposed primary east of Gypsum Canyon, shall be monitored as determined necessary by the project paleontologist during grading operations. Recommended hours for monitoring activities shall be established by the project paleontologist and shall be outlined in the monitoring plan. It shall be the responsibility of the project paleontologist to demonstrate, to the satisfaction of the City, the appropriate level of monitoring necessary based on the tentative tract or' parcel map level grading plans, when available. Because of the potential for identifying microfossils or small fragments of macrofossils, periodic screening of sands from cuts in these units shall be done by the project paleontologist monitor. Such material may be removed in bulk and screened off-site to minimize interference with grading operations.

C. Any paleontological work at the site shall be conducted under the direction of a County of Orange Certified paleontologist (project paleontologist).

e.

If a fossil discovery occurs during grading operations when the project paleontologist is not present, grading shall be diverted around the area until the monitor can survey the area, and/or Caltrans Cultural Resources staff can inspect the site; if the resources are found within Caltrans right-of-way.

Any fossils recovered during the development, along with their contextual stratigraphic data, shall be donated to the County of Orange, or other appropriate institution with an educational and research interest in the materials. A final 'report detailing findings and disposition of specimens shall be prepared by the project paleontologist and submitted to the City of Anaheim Planning Department upon completion of grading.

soon as possible to all future roadway areas
• Barriers can be used to ensure vehicles are
only used on established parking areas/haul
routes
• Pre-watering of soils prior to trenching is
an effective preventiv~ measure.
• For deep trenching activities, pre-trench to
18 inches, soak soils via the pre-trench, and
resume trenching
• Washing mud and soils from equipment at
the conclusion of trenching activities to
prevent crusting and drying of soil on
equipment

2 MITIGATION MONITORING PROCEDURES
On August 23, 2005, a Final EIR (Mountain Park Specific Plan Amendment Final EIR No. 331 [State Clearinghouse (SCH) No. 2004071098]) was certified by the Anaheim City Council along with the adoption of a Mitigation Monitoring Program (Mitigation Monitoring Program No. 137). This Final EIR, herein referred to as “EIR No. 331” or the “Certified EIR”, identified potentially significant impacts that could be reduced to less than significant levels with incorporation of project design features, Standard Conditions, and mitigation measures.

As stated above, Mitigation Monitoring Program No. 137 (MMP No. 137) was prepared for the Mountain Park Specific Plan No. 90-4, Amendment No. 1 (Approved Project) in compliance with PRC Section 21081.6. It describes the requirements and procedures to be followed by the City of Anaheim (City) to ensure that measures adopted for the Approved Project as certified by the City Council would be implemented and monitored appropriately. This document presents modifications to MMP No. 137 to address the Gypsum Canyon Cemetery Project (Proposed Project).

Because environmental analysis for the Proposed Project has been prepared as an Addendum to EIR No. 331, mitigation included within MMP No. 137 can be utilized to address potential environmental impacts of the Proposed Project. However, the Proposed Project would only affect Development Area 5 (project site) of the Mountain Park Specific Plan Area, while Mitigation Monitoring Program No. 137 addressed the Mountain Park Specific Plan Area in its entirety. As such, mitigation measures, Standard Conditions, and Project Design Features included in MMP No. 137 that do not pertain to the project site, or the currently proposed development type, would not be applicable to the Proposed Project and have been omitted from the modified mitigation monitoring program or have been modified to ensure applicability.

Table 1.A, Applicability of Mitigation Measures Identified in MMP No. 137, lists each of the mitigation measures specified in EIR No. 331 that would be relevant to the Proposed Project and identifies any modifications that would ensure applicability to the Proposed Project.

COMPLIANCE MEASURE MONITORING PROCEDURES
Table 1.B, Applicability of Standard Conditions Identified in MMP No. 137, lists Standard Conditions of approval identified under the Approved Project that would be applicable to the Proposed Project. Table 1.B describes the requirements and procedures to be followed by the City to ensure that all applicable Standard Conditions adopted as part of the Proposed Project will be carried out as described in EIR No. 331 or as modified to ensure applicability to the Proposed Project.

PROJECT DESIGN FEATURE MONITORING PROCEDURES
Table 1.C, Applicability of Project Design Features Identified in MMP No. 137, lists Project Design Features identified under the Approved Project that would be applicable to the Proposed Project.

Table 1.C describes the requirements and procedures to be followed by the City to ensure that all applicable Project Design Features included in the design of the Approved Project will be carried out as described in EIR No. 331 or as modified to ensure applicability to the Proposed Project. 3 M ODIFICATIONS TO MITIGATION MONITORING P ROGRAM N O . 137 M AY 2024

 Use of rodenticides and herbicides in project sites shall be restricted.

This is necessary to prevent primary or secondary poisoning of predators and the depletion of prey populations on which they depend. All uses of such compounds shall observe label and other restrictions mandated by the United States Environmental Protection Agency, the California Department of Food and Agriculture, and other State and federal legislation.

MM 6-2 Prior to the approval of mass or rough grading plans issuance of grading permits impacting jurisdictional areas, the property owner/developer shall provide a wetland mitigation plan approved by the ACOE (for Section 404 areas) and CDFWG (for the Section 1602 areas) to the Department of Public Works. A total of 14.1 acres of riparian mitigation are necessary to offset the loss of ACOE and CDFWG jurisdictional areas as a result of the Proposed Project. A Conceptual Wetland and Riparian Habitat Mitigation Plan has been prepared by LSA (February, 2005). The purpose of the mitigation plan is to:
 Create (establish), restore, or enhance wetland/riparian habitats on site to the maximum extent practicable to minimize the on-site loss of ACOE and CDFWG jurisdictional acreage and function, and provide off-site mitigation for the remainder of the impacts;
 To implement, to the extent practicable, off-site mitigation in the Santa Ana River watershed, as close to the study area as possible or otherwise at a key ecological site;
 To return jurisdictional habitats that are temporarily disturbed during construction to pre-construction conditions; and,
 To ensure that adjacent non-jurisdictional habitats are protected.  The project disturbance limits shall be clearly marked with construction fencing (or other highly visible material), and construction/materials staging and vehicle/equipment maintenance and fueling areas shall be located at least 100 ft away from Gypsum Canyon Channel, where feasible.

 To minimize temporary disturbances, all project-related vehicle traffic shall be restricted to established roads, construction areas, and other designated areas.

The preferred on-site mitigation approach shall be approved by the ACOE, CDFWG and RWQCB during the permitting process. One possible component of the on-site mitigation, to address the impacts of the box extension on the already disturbed Gypsum Creek channel, could include a rebuilt creek as a low-flow riparian corridor through the canyon mouth area. Conceptually, the box extension shall act as a high-flow by-pass that efficiently conveys the more intense and destructive flood flows.

The riparian corridor shall extend upstream to the road crossing of Gypsum Creek. The riparian corridor shall consist of a riverine channel flanked by planted embankments. The riverine channel would be soft bottom and the riparian vegetated floor would be nurtured by low and seasonal run-off diverted into it from a channel split from the new box culvert opening. This "splitter" shall consist of a junction opening that becomes a tunnel that would accommodate storm flows as well as wildlife movement under the road crossing to the riparian corridor.

MM 6-3 Prior to approval of mass or rough grading plans a grading permit, the property owner/developer shall submit copies of contractor specifications to the Department of Public Works/Planning & Building Department that include the following note: “Initial clearing of vegetation that has been identified as being used by the southwestern willow flycatcher shall be conducted outside of the breeding season or with the presence of a biological monitor during the breeding season to ensure that no individuals of this species are directly impacted. The breeding season for the southwestern willow flycatcher is between May 15 and July 31.” Following completion of initial clearing of vegetation, the project biological monitor shall provide written evidence to the Planning & Building Department that this measure has been completed.

the 91 Freeway and within Gypsum Creek: (1) construction activities to lengthen the culverts shall be scheduled outside of the critical breeding time (May April 1 through August 1531) to avoid direct impacts; (2) if construction must occur between May April 1 and August 1531, all construction activities shall occur outside the current culverts and no deeper than 25 feet inside the culverts to avoid a negative effect on the colony, (3) no night work shall occur around the culvert openings and only construction lighting necessary for safety purposes shall be used near the culvert openings and 4) design lighting such that it minimizes light trespass into adjacent habitat. All lighting fixtures will have light shields or similar devices (e.g., Dark Sky-compliant lighting) installed to minimize illuminance above the site and avoid light trespass into Gypsum Creek and other adjacent open space areas. The color temperature of the light emitted by the luminaires should be less than 2700 Kelvin to minimize adverse effects to wildlife, including bats. The specifications shall be prepared by a CDFW approved bat biologist. Following completion of construction activities associated with the culverts, the project biological monitor shall provide written notification to the Planning Department that the contractor specifications have been complied with.

The specifications shall also include the conduction of a bat habitat assessment of suitable roosting trees prior to construction. If trimming or removal of suitable roosting trees are identified within the project work area, a CDFW approved bat biologist will work with the construction contractor during the trimming and removal process. Trees and snags that have been identified as confirmed or potential roost sites require a two-step removal process and the involvement of the bat biologist to ensure that no roosting bats are killed during this activity.

This two-step removal shall occur over 2 consecutive days as follows. On Day 1, branches and limbs not containing cavities, as identified by a qualified bat biologist, will be removed. On Day 2, the remainder of the tree may be removed without supervision by a bat biologist. The disturbance caused by limb or frond removal, followed by an interval of 1 evening, will allow bats to safely abandon the roost.

This would ensure that no active nests would be disturbed and that removal could proceed rapidly.

If vegetation removal activities shall occur during the nesting season (February 15 to July 15), all suitable habitat shall be thoroughly surveyed for the presence of nesting birds by a qualified biologist prior to removal.

If any active nests are detected, the area shall be flagged, along with a minimum 50-foot buffer (buffer may range between 50 and 300 feet as determined by the monitoring biologist) and shall be avoided until the nesting cycle is complete or it is determined by the monitoring biologist that the nest has failed.” In addition, a biologist shall be present on the site to monitor the vegetation removal to ensure that nests not detected during the initial survey are not disturbed. The project biological monitor shall provide written notification to the Planning & Building Department that these requirements have been accomplished following completion of grading activities associated with each grading permit.

During construction of the Proposed Project, the property owner/development and its contractors shall be required to comply with regional rules, which shall assist in reducing short-term air pollutant emissions. SCAQMD Rule 402 requires that air pollutant emissions not be a nuisance off-site. SCAQMD Rule 403 requires that fugitive dust be controlled with the best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. Two options are presented in Rule 403: monitoring of particulate concentrations or active control. Monitoring involves a sampling network around the project with no additional control measures unless specified concentrations are exceeded. The active control option does not require any monitoring but requires that a list of measures be implemented starting with the first day of construction.

Rule 403 requires that “No person conducting active operations without utilizing the applicable best available control measures included in Table 1 of this Rule to minimize Fugitive dust emissions from each fugitive dust source type within the active operation.” The measures from Table 1 of Rule 403 are presented in Table 15 in Appendix H of EIR No. 331. The applicable measures presented in Table 1 are required to be implemented by Rule 403.
 Rule 403 requires that “Large Projects” implement additional measures. A Large Project is defined as “any active operations on property which contains 50 or more acres of disturbed surface area; or any earth-moving operation with a daily earth-moving or throughput volume of 3,850 cubic meters (5,000 cubic yards) or more three times during the most recent 365 day period. Grading of the project would be considered a Large Project under Rule 403.

Therefore, the project shall be required to implement the applicable actions specified in Table 2 of the Rule. Table 2 from Rule 403 is presented in Table 16 of Appendix H. As a Large Operation, the project shall also be required to:
 Submit a fully executed Large Operation Notification (SCAQMD Form 403N) to the SCAQMD Executive Officer within 7 days of qualifying as a large operation;
 Include, as part of the notification, the name(s), address(es), and phone number(s) of the person(s) responsible for the submittal, and a description of the operation(s), including a map depicting the location of the site;
 Maintain daily records to document the specific dust control actions taken, maintain such records for a period of not less than three years; and make such records available to the Executive Officer upon request.
 Install and maintain project signage with project contact signage that meets the minimum standards of the Rule 403 Implementation Handbook, prior to initiating any earthmoving activities. 11 M ODIFICATIONS TO MITIGATION MONITORING P ROGRAM N O . 137 M AY 2024

 Identify a dust control supervisor that is employed by or contracted with the property owner/developer, is on the site or available on-site within 30 minutes during working hours, has the authority to expeditiously employ sufficient dust mitigation measures to ensure compliance with all Rule requirements, and has completed the AQMD Fugitive Dust Control Class and has been issued a valid Certificate of Completion for the class.
 Notify the SCAQMD Executive Officer in writing within 30 days after the site no longer qualifies as a large operation.

Rule 403 also requires that the construction activities “shall not cause or allow PM10 levels exceed 50 micrograms per cubic meter when determined by simultaneous sampling, as the difference between upwind and downwind sample.” Large Projects that cannot meet this performance standard are required to implement the applicable actions specified in Table 3 of Rule 403. Table 3 from Rule 403 is presented in Table 17 of Appendix H. Rather than perform monitoring to determine conformance with the performance standard, which will not reduce PM10 emissions, the project shall implement all applicable measures presented in Rule 403 Table 3 regardless of conformance with the Rule 403 performance standard. This potentially results in a higher reduction of particulate emissions than if these measures were implemented only after being determined to be required by monitoring.

Further, Rule 403 requires that that the project shall not “allow track-out to extend 25 feet or more in cumulative length from the point of origin from an active operation.” All track-out from an active operation is required to be removed at the conclusion of each workday or evening shift. Any active operation with a disturbed surface area of five or more acres or with a daily import or export of 100 cubic yards or more of bulk materials must utilize at least one of the measures listed in Table 18 of Appendix H at each vehicle egress from the site to a paved public road.

3.10 Hazards and Hazardous Materials
MM 10-1 The Robertson’s Ready Mix Quarry area will not be developed until after reclamation and remediation are complete. Based on the Environmental Site Assessments performed for the project site (included in Appendix J), it is not anticipated that any underground storage tanks, septic systems, leach fields, or significant soil contamination will be encountered during construction, as construction shall occur after remediation and reclamation are complete (all regulatory agency cases on-site are closed). As described in the Phase I ESA (December 2023), residual shallow soil and groundwater contamination associated with prior mining activities and historic ADL contamination associated with SR-91 could be encountered during construction and were identified as RECs.

Prior to the issuance of a grading permit, a Phase II ESA shall be conducted in order to confirm the presence/absence of these RECs and whether any further remedial actions would be required prior to or during grading activities.

During grading activities, in the event these subsurface features or contaminated soil are encountered, work shall immediately cease in the area and the property owner/developer shall notify the Fire Department and Public Utilities, Environmental Services Division, other agencies as appropriate based on the circumstances of the contamination, and retain a qualified hazardous materials engineer or geologist to assess the impacts and prepare a response plan using risk-based cleanup standards of the City of Anaheim and the Orange County Health Care Agency, and any appropriate guidelines issued by the California Environmental Protection Agency, applicable to residential land use the Proposed Project. Upon approval of the response plan by the Fire Department or other agency, as applicable, the engineer shall obtain any required permits, oversee the removal of such features and/or conduct the response work to the satisfaction of the Fire Department or other agency, as applicable, until closure status is attained.

head to convey 5,500 cfs through the culvert into Featherly Park.

The elevation difference between the flow line of the culvert inlet and the top of the road is expected to be approximately 20 feet, allowing for a freeboard of three feet. The extension of the culvert upstream, with the described design modifications to the inlet control, will prevent flooding onto Gypsum Canyon Road during large storm events. The proposed modification of the culvert will improve the flood control design capacity of the culvert from a 10- year storm event to a 100-year storm event. A confirmation of the structural integrity and design calculations of the existing culvert structure shall be completed prior to final design of the new box culvert extension.

B. West Drainage Area Storm Drain Improvement: Minor storm drain improvements to an existing undersized 36-inch reinforced concrete pipe (RCP) that collects off-site runoff from the undisturbed slopes draining into The Summit will be upsized to the capacity of a 54-inch RCP for proper conveyance of the project flows into the existing 66- inch RCP.

C. SR-91/Gypsum Canyon Road Storm Drain Improvement: A minor storm drain improvement will be implemented for the 4-acre sub- area that used to drain into the existing culvert inlet but will not adequately drain after the culvert extension. The improvement will consist of a riser tower and a RCP (size to be determined) to collect the flows and connect directly into the triple box culvert at the approximate location of the existing culvert inlet.

D. Featherly Regional Park Channel Improvements: The
improvements to the box culvert outlet for energy dissipation of flood flows will include a concrete apron followed by riprap to reduce velocities down to the 10 to 12 feet per second (fps) range.

Riprap will also be added to the embankments beyond the concrete apron. To provide additional stabilization of the channel downstream, flow velocities will be decreased to the range of 10 to 12 fps where turf-reinforced mesh blankets will be used, and vegetation re-established along the channel bottom and
