Discussion
a. The proposed project’s potential to result in water quality impacts during construction and operations is discussed in further detail separately below.

Construction
Project construction activities such as grading, excavation, and trenching for site improvements would result in the disturbance of on-site soils. The exposed soils have the potential to affect water quality in two ways: 1) suspended soil particles and sediments transported through runoff; or 2) sediments transported as dust that eventually reach local water bodies. Spills or leaks from heavy equipment and machinery, staging areas, or building sites also have the potential to enter runoff. Typical pollutants include, but are not limited to, petroleum and heavy metals from equipment and products such as paints, solvents, and cleaning agents, which could contain hazardous constituents. Sediment from erosion of graded or excavated surface materials, leaks or spills from equipment, or inadvertent releases of building products could result in water quality degradation if runoff containing the sediment or contaminants should enter receiving waters in sufficient quantities. Impacts from construction-related activities would generally be short-term and of limited duration.

Water quality degradation is regulated by the federal NPDES Program, established by the Clean Water Act, which controls and reduces pollutants to water bodies from point and non-point discharges. In California, the NPDES permitting program is administered by the

State Water Resources Control Board (SWRCB) through nine Regional Water Quality Control Boards (RWQCBs). As discussed in Section VII, Geology and Soils, of this IS/MND, new development within the City that disturbs one or more acres of land is required to comply with the NPDES Construction General Permit and prepare a SWPPP incorporating BMPs to control sedimentation, erosion, and hazardous materials contamination of runoff during construction. The proposed project would disturb approximately two acres and, thus, would be subject to the State NPDES Construction General Permit conditions.

The proposed project would also be subject to all regional and local water quality regulations. In order to meet water quality objectives for the region, the City of Morgan Hill, City of Gilroy, and County of Santa Clara have prepared and are implementing a Revised Regional SWMP. The SWMP incorporates the efforts of the City of Morgan Hill, the City of Gilroy, and the unincorporated portion of Santa Clara County, within the watershed of the Pajaro River and Monterey Bay, to meet the Phase II Storm Water Permit requirements for small municipal separate storm sewer systems (MS4s). The Upper Pajaro River Watershed is located within the jurisdiction of the Central Coast RWQCB.

The City of Morgan Hill implements the SWMP through an extensive program that entails:
1) the establishment of SWMP goals for the City; 2) public education and outreach; 3) public involvement and participation; 4) illicit discharge control; 5) construction site stormwater runoff control; 6) post-construction stormwater management in development; and 7) pollution prevention. For construction activities, the SWMP presents BMPs that are required for the control of stormwater runoff quality during construction, including, but not limited to, covering disturbed areas with mulch, temporary seeding, soil stabilizers, binders, fiber rolls or blankets, temporary vegetation, and permanent seeding.

Operation
After project completion, impervious surfaces on the project site could contribute incrementally to the degradation of downstream water quality during storm events. During the dry season, vehicles and other urban activities may release contaminants onto the impervious surfaces, where they would accumulate until the first storm event. During the initial storm event, or first flush, the concentrated pollutants would be transported via stormwater runoff from the site to the stormwater drainage system and eventually a downstream waterway. Typical urban pollutants that would likely be associated with the proposed project include sediment, pesticides, oil and grease, nutrients, metals, bacteria, and trash. In addition, stormwater runoff could cause soil erosion if not properly addressed and provide a more lucrative means of transport for pollutants to enter the waterways.

A Preliminary Stormwater Control Plan was prepared by MH Engineering Co. to assess the proposed project’s compliance with the Central Coast RWQCB’s Post-Construction Stormwater Compliance Resolution and the Stormwater Management Guidance Manual for Low Impact Development & Post Construction Requirements (see Appendix E). 27 The
proposed project would be managed in accordance with Resolution R3-2013-0032 issued by the Central Coast RWQCB. This resolution formally adopts post-construction stormwater management requirements for development projects in the Central Coast Region. The requirements identify 10 Watershed Management Zones (WMZs) in the covered area, and specify stormwater management requirements for each zone, depending on the size of the development project. Because the proposed project site is 27 MH Engineering Co. Preliminary Stormwater Control Plan for The Gates. June 29, 2022.

located in an area classified as WMZ-1, stormwater management at the project site must include site design and runoff features to limit the amount of runoff from the project site as well as on-site water quality treatment to reduce pollutant loads in the stormwater runoff using a Low Impact Development (LID) treatment system such as biofiltration. In WMZ-1, the treatment system must retain 95 percent of the runoff from the project site and also maintain peak runoff flows such that they do not exceed pre-project flows.

Currently, the project site contains a manmade ditch that conveys stormwater run-on flows from neighboring properties through the central portion of the site to three 24-inch corrugated metal pipe (CMP) culverts, which proceed under Monterey Road and release runoff to a 48-inch culvert. From the 48-inch culvert, flows are then discharged to an offsite detention basin to the east of Monterey Road and the UPRR tracks. In addition, runon is also conveyed from the on-site ditch to an existing 18-inch culvert, which flows northwest along the project frontage before discharging into an existing storm drain along Monterey Road (see Figure 9). Finally, an existing storm drain line is located along the site’s western boundary.

As part of the proposed project, the existing on-site drainage infrastructure would be reconfigured by backfilling the manmade ditch and extending the three 24-inch culverts and 18-inch culvert towards the west from the project site’s eastern boundary to the site’s western property line, which would avoid disrupting the existing conveyance of flows from neighboring properties that currently drain flows through the project site to the off-site detention basin (see Figure 10). Additionally, on-site stormwater runoff from impervious surfaces overlain as part of the project would not enter the proposed culvert extension.

Instead, runoff from on-site impervious surfaces would be collected by a series of new drain inlets along the internal parking areas, drive aisles, and paved walkways. From the inlets, flows would be transported by way of new internal storm drain lines to the proposed bioretention/detention pond, which would be sited in a Private Storm Drainage Easement in the southern portion of the project site (see Figure 11).

As detailed in the Preliminary Stormwater Control Plan, the bioretention/detention pond would be used for the required retention volume storage and peak-flow management. The bioretention/detention pond would be located at the lowest point on-site to conform to the existing terrain and watersheds with a bottom elevation of 347.85 feet. The proposed bioretention/detention pond would retain stormwater until an elevation of 348.85 feet to meet the required retention volumes. Once water surface elevation rises above 348.85 feet, the bioretention pond would release below pre-development levels through a 10-inch standpipe into the City’s existing storm drain system along Old Monterey Road. Pursuant to the Preliminary Stormwater Control Plan, the bioretention/detention pond would provide 11,961 cubic feet of retention volume, which would exceed the required minimum volume of 11,907 cubic feet.

In addition, pursuant to Chapter 18.140 (Post Construction Stormwater Pollution Prevention) of the City’s Municipal Code, the proposed project would be subject to permanent storm water pollution prevention measures. As such, the proposed project would be required to comply with the design standards set forth in Section 18.140.040 (Design standards and selection of best management practices), and select and implement BMPs to the satisfaction of the City in accordance with the requirements contained in the most recent versions of the following documents:

4. City of Morgan Hill Hydro-modification Management Plan, as approved by the Central Coast Regional Water Quality Control Board.

The final design of the proposed drainage system would be reviewed and approved by the City of Morgan Hill Engineering Land Development Division, which would ensure that the proposed drainage system complies with the City’s Post Construction Stormwater Pollution Prevention Ordinance with respect to incorporating sufficient permanent stormwater treatment control BMPs. Therefore, water quality standards or waste discharge requirements would not be violated, and water quality would not be degraded as a result of the proposed project operations.

Conclusion
Based on the above discussions, the proposed project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality during construction and operations. Therefore, a less-thansignificant impact would occur. b,e. The City’s water supplies currently consist entirely of groundwater. Approximately 25 percent of the City’s supply is extracted from the Coyote Valley subarea of the Santa Clara Subbasin, and approximately 75 percent is extracted from the Llagas Subbasin. The project site is located within the Santa Clara Subbasin. Neither of the subbasins are in a condition of overdraft, and groundwater levels are not expected to drop.28 It should be noted that water supply is discussed in Section XIX, Utilities and Service Systems, of this IS/MND.

According to the General Plan EIR, the SCVWD manages all groundwater basins within Santa Clara County and uses a Groundwater Recharge Program to maintain groundwater levels. The SCVWD provides about 26 percent of recharge with imported raw water and about 34 percent by way of releases from local reservoir storage. Rainfall percolation accounts for the remaining 40 percent of replenishment. Because the basins are not adjudicated, the maximum supply available to the City is its maximum capacity. The General Plan EIR evaluated the potential for development facilitated by buildout of the General Plan to substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table and found that while such development could lead to an increased demand for water and groundwater pumping, water supply exceeds demand by at least 6,000 acre-feet per year (AFY). Additionally, the General Plan EIR accounted for the SCVWD’s Groundwater Recharge Program and concluded that through compliance with all applicable General Plan policies and actions, a less-than-significant impact would occur. Approval of the General Plan Amendment would ensure consistency with the General Plan and the site’s zoning district and the project would comply with all applicable 28 City of Morgan Hill.

polices, standards, and regulations set forth by the City’s General Plan and Municipal Code. Therefore, the proposed project would not result in impacts beyond what were concluded in the General Plan and would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin.

Additionally, as the exclusive groundwater management agency for Santa Clara County, the SCVWD serves as the local Groundwater Sustainability Agency (GSA), in accordance with the Sustainable Groundwater Management Act (SGMA). The SGMA requires local agencies to form GSAs, which develop and implement Groundwater Sustainability Plans to avoid undesirable results and mitigate overdraft within 20 years. The SCVWD-adopted 2016 Groundwater Management Plan (GWMP) for the Santa Clara and Llagas Subbasins describes SCVWD’s groundwater sustainability goals, and the strategies, programs, and activities that support such goals. In 2019, the Department of Water Resources (DWR) approved the GWMP for both the Santa Clara and Llagas Subbasins, determining it satisfies the objectives of SGMA. According to DWR, the Santa Clara Subbasin is a medium-priority subbasin.29 Recharge within the Santa Clara Subbasin generally occurs along the margins and southern portion of the subbasin where coarse‐grained sediments predominate.

While the proposed project would include development of new impervious surfaces on the project site, as discussed under question ‘a’ above, on-site stormwater runoff from impervious surfaces would be collected by new on-site storm drainage infrastructure and routed to a new bioretention/detention pond, which would provide water quality treatment and peak management at pre-project levels for on-site runoff. Runoff collected by the project’s stormwater facilities would ultimately be discharged to the City’s existing stormwater drain located along Old Monterey Road during large storm events.

Based on the above, the proposed project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin or conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. Thus, a less-than-significant impact would occur. ci-iii. The project site is undeveloped and consists of ruderal grassland, various shrubbery scattered throughout, and small trees located along the eastern and western borders. The project site also includes 28 parking spaces within the existing Starbucks parking lot located to the northwest and an existing manmade ditch. Development of the proposed project would include approximately 112,024 square feet of impervious surfaces, which would alter the existing drainage pattern of the site. However, as discussed above, on-site stormwater runoff would be collected by a series of drain inlets and transported by way of underground storm drain lines to a bioretention/detention pond. The bioretention/detention pond would allow stored runoff to infiltrate underlying soils in a manner similar to what currently occurs on-site. During large storm events, excess runoff would be discharged to the City’s public storm drain system located in Old Monterey Road. The bioretention/detention pond would treat and retain runoff from the project site and also maintain peak runoff flows such that they do not exceed pre-project flows, in accordance with the stormwater management requirements adopted by Resolution R3-2013-0032. 29 Santa Clara Valley Water District. 2016 Groundwater Management Plan, Santa Clara and Llagas Subbasins [pg. 1-1]. November 2016.

Furthermore, stormwater runoff associated with the site would be required to comply with the City’s SWMP standards. As such, the project would not significantly increase stormwater flows into the existing system. The final drainage system design for the project would be subject to review and approval by the City of Morgan Hill Engineering Land Development Division, who would confirm that the proposed drainage system for the project is consistent with the City’s Storm Drainage Master Plan and standard stormwaterrelated conditions of approval.

As noted above, the proposed project would convert the existing on-site manmade drainage ditch to a series of pipe extensions that would underly the proposed development. The three existing 24-inch culverts and 18-inch culvert would be extended from the site’s eastern boundary to the western property line. The existing 24-inch culverts are currently inlet controlled, which would dictate the flows across the site. According to a Floodplain Impact Memorandum prepared for the proposed project by Schaaf & Wheeler Consulting Civil Engineers (see Appendix F),30 extension of the pipes under the site would provide for equal conveyance of runoff to what currently occurs with the existing drainage ditch. Even under worst-case, maximum flow conditions, the hydraulic modeling conducted as part of the Floodplain Impact Memorandum determined that the upstream head would be the same under the proposed project as under existing conditions.

Additionally, on-site runoff from new impervious surfaces associated with development of the proposed project would not enter the proposed culvert extensions, but would be handled by a new on-site stormwater system, completely separate from the culvert, as described above.

Therefore, the proposed project would not substantially alter the existing drainage pattern of the site or area in a manner that would result in substantial erosion, siltation, or flooding on- or off-site, create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems, or provide substantial additional sources of polluted runoff. Thus, a less-than-significant impact would occur. civ. According to Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM), the project site is located primarily within a Special Flood Hazard Area (SFHA) (Zone AH), which is defined as an area with one percent annual chance of shallow flooding with an average depth ranging from one to three feet and a Base Flood Elevation (BFE) of 354 feet (see Figure 12).31 As such, in order to ascertain potential impacts associated with the project site’s location within the 100-year floodplain, a Floodplain Impact Memorandum was prepared by Schaaf & Wheeler Consulting Civil Engineers (see Appendix F).32
Based on a hydraulic impact analysis using modeled flows from Llagas Creek, Schaaf & Wheeler concluded that the spills from Llagas Creek do not reach the project site and that the site could be removed entirely from the floodplain through a Letter of Map Revision (LOMR) process (see Figure 13 and Figure 14). However, approval of a LOMR can take anywhere from six weeks to six months.

Pursuant to the City’s Floodplain Ordinance (Section 15.80.160 of the Morgan Hill Municipal Code), without a LOMR, development within a SFHA is required to be anchored, constructed with flood resistant materials and designed to minimize flood damage, and elevated to at least one foot above the base flood elevation (within the AH Zone).

As discussed above, the proposed project would convert the existing on-site manmade drainage ditch to three new 24-inch culverts and a new 18-inch culvert that would extend from the existing culverts located near the site’s eastern boundary to the western property line. The modification would provide equal conveyance of stormwater run-on from neighboring properties and the private (Butterfield) detention basin as compared to what currently occurs within the existing drainage ditch. Even under worst-case, maximum flow conditions, the hydraulic modeling conducted as part of the Floodplain Impact Memorandum determined that the upstream head would be the same under the proposed project as under existing conditions. Because pre-development and post-development flows associated with the run-on conveyance through the site would be the same, the conversion of the conveyance infrastructure from an open drainage ditch to culverts would not have the potential to impede or redirect flood flows. In addition, any overland spills from the detention basin would not be directed onto the project site, as the slope of Monterey Road is in the southern direction.

Given that the project site is located within a SFHA and a LOMR has not been approved for the project site, the potential exists that the project could alter the existing drainage pattern of the site or area in a manner which would impede or redirect flood flows, and a potentially significant impact could occur.

Mitigation Measure(s)
Implementation of the following mitigation measure would reduce the above potential impact to a less-than-significant level.

X-1. Finished building pad elevations shall be a minimum of one foot above the 100-year floodplain line, in accordance with Section 15.80.160 of the Morgan Hill Municipal Code, and shall be shown on project Improvement Plans prior to their approval. The final pad elevation shall be certified by a California registered civil engineer or licensed land surveyor and submitted to the City Engineer. This certification shall be done prior to construction of the foundation or at the completion of final grading, whichever comes first.

No building construction is allowed until the certification has been received by the City Engineer and approved by the floodplain manager. Benchmark elevation and location shall be shown on the Improvement Plans to the satisfaction of the Morgan Hill Development Services Department. d. A seiche is defined as a wave generated by rapid displacement of water within a reservoir or lake, due to an earthquake that triggers land movement within the water body or land sliding into or beneath the water body. The project site is not located near a water body that is susceptible to seiche hazard. In addition, the distance to the nearest coastline does not subject the site to tsunami hazards. The project site is within the dam failure inundation hazard zone for Anderson Reservoir as indicated within the dam failure inundation hazard maps.33

The dams in Santa Clara County are managed by the SCVWD. The dams are inspected twice each year and are continuously monitored for seepage and settling and inspected immediately following significant earthquakes. A seismic stability evaluation performed in 2007 for Anderson Dam indicated that the downstream and upstream embankments could become unstable during a very large magnitude earthquake and the rupture of faults underlying the dam may have adverse impact on the outlet pipes and intake structure. The SCVWD has initiated a capital project, the Anderson Dam Seismic Retrofit Project (ADSRP), to complete the planning, design, and construction of the seismic retrofit of the dam. Construction work for the ADSRP was planned to start in 2021.34 Until recently, in order to protect the public from potential effects until the ADSRP is complete, a storage restriction of approximately 45 feet below the dam crest has been put in place, with a reduced storage capacity of 61,810 acre-feet. The SCVWD and regulatory agencies (California Division of Safety of Dams and the Federal Energy Regulatory Commission) have approved the restriction and believe that the restriction would be sufficient to prevent the uncontrolled release of water in case of dam failure after a major earthquake. As of December 2020, Anderson Reservoir, the largest reservoir in Santa Clara County, has been completely drained under the direction of federal dam regulators.

Based on the above, the proposed project would not be exposed to substantial risks related to flooding as a result of the failure of a dam, tsunamis, or seiches. In addition, as discussed under question ‘civ’ above, the proposed project would not present significant impact within a 100-year floodplain. Therefore, the project would not result in the release of pollutants due to project inundation, and a less-than-significant impact would occur. 34 Santa Clara Valley Water District.

   
Discussion
a. A project risks dividing an established community if the project would introduce infrastructure or alter land use so as to change the land use conditions in the surrounding community or isolate an existing land use. The project site is currently undeveloped.

Through approval of the proposed General Plan Amendment and Rezone the proposed project would be consistent with the Morgan Hill General Plan. Furthermore, the project’s residential component would be compatible with the existing single-family residential neighborhood to the northwest, west, and southwest of the project site. The project’s commercial component would be consistent with the existing commercial uses to the north of the site. The City’s existing roadway system would not be modified by the project.

Additionally, the project would include sidewalk improvements along the new neighborhood roads to increase pedestrian connectivity in the project area. Therefore, the proposed project would be a continuation of the surrounding development and would not isolate an existing land use. As such, the project would not physically divide an established community, and a less-than-significant impact would occur. b. The project site is currently undeveloped ruderal grassland. The City’s General Plan land use designation for the site is C, and the City’s zoning designations for the site are PD and GC .Through approval of a General Plan Amendment and Rezone, the project site would have a Mixed Use Flex land use designation and MU-F zoning. In addition, if the General Plan Amendment and Rezone were to be approved, the project site would be located within the Monterey Road Corridor for which a Block Level Master Plan (BLMP) is generally required for all projects wanting to develop within the block, subject to certain requirements of State law established by California SB 330. Pursuant to Section

18.22.020 (Land Use Regulations), the project would be consistent with regulations accommodating accessory dwelling units, mixed use residential units, parks and recreational facilities, restaurants, professional offices, general retail, and medical offices and clinics which are considered permitted and administrative uses within the MU-F zone district, and do not require approval of a Conditional Use Permit with certain exceptions.

As such, the proposed project site would include five flexible commercial spaces and seven residential buildings containing a total of 49 townhome style condominium.

Furthermore, as discussed throughout this IS/MND, the proposed project would not result in any significant environmental effects that could not be mitigated to a less-thansignificant level. Through approval of a General Plan Amendment and Rezone, the proposed project would generally be consistent with General Plan policies, as well as other applicable policies and regulations adopted for the purpose of avoiding or mitigating environmental effects. For example, with implementation of Mitigation Measures IV-1 through IV-5 that include preconstruction surveys for burrowing owls and nesting/migratory birds, compliance with the Clean Water Act, as well as mitigated removal of Ordinance Sized Trees, the project would not conflict with any applicable policies, regulations, or ordinances related to the protection of biological resources. As discussed under Section XIII, Noise, of this IS/MND, the project would comply with the noise level thresholds established in the City’s General Plan and the Municipal Code

during construction or operation with implementation of Mitigation Measure XII-1 and XII2.

Based on the above, the proposed project would not cause a substantial adverse environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect, and a less-thansignificant impact would result.

a,b. The City’s General Plan does not identify any regionally or locally important mineral resources within the City of Morgan Hill. The Santa Clara County General Plan does identify mineral resources of importance; however, the project site is not in proximity to the quarries currently in operation. Consequently, the proposed project would not result in the loss of a known mineral resource that would be of value to the region nor would the project result in the loss of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan. Therefore, no impact to mineral resources would occur as a result of the proposed project.

   
Discussion
a. The following section is based primarily on an Exterior Noise and Façade Acoustical Analysis prepared for the proposed project by Veneklasen Associates,35 and includes a discussion of noise standards and criteria applicable to various land uses, as well as potential traffic noise and non-transportation noise sources associated with the proposed project. The following terms are referenced in the sections below:
• Decibel (dB): A unit of sound energy intensity. An A-weighted decibel (dBA) is a decibel corrected for the variation in frequency response to the typical human ear at commonly encountered noise levels. All references to dB in this section will be Aweighted unless noted otherwise. • Day-Night Average Level (Ldn): The average sound level over a 24-hour day, with a +10 decibel weighing applied to noise occurring during nighttime (10:00 PM to 7:00 AM) hours.
• Equivalent Sound Level (Leq): The average sound level over a given time-period. • Maximum Sound Level (Lmax): The maximum sound level over a given time-period. • Median Sound Level (L50): The sound level exceeded 50 percent of the time over a given time-period.

Sensitive Receptors
Noise-sensitive land uses are generally defined as locations where people reside or where the presence of unwanted sound could adversely affect the primary intended use of the land. Places where people live, sleep, recreate, worship, and study are considered to be sensitive to noise because intrusive noise can be disruptive to such activities. Within the project vicinity, the nearest sensitive receptors are the multi-family residences located north of the project site, across Monterey Road, approximately 140 feet away.

Existing Noise Environment
The ambient noise environment in the immediate project vicinity is defined by traffic on Monterey Road and rail activity associated with the adjacent UPRR tracks. On November 8, 2021, four short-term and two long-term noise measurements were conducted by 35 Veneklasen Associates.

Veneklasen Associates using two Bruel & Kjaer type 2270 sound level meters to determine the existing noise environment. For the long-term noise measurements, one meter was placed 40 feet from the UPRR, and the other meter was placed approximately 100 feet from Monterey Road. Table 7 shows a summary of the noise measurements.

City Noise Standards and Criteria
Chapter 9, Safety, Service, and Infrastructure, of the City’s General Plan contains the following policies that would be applicable to the proposed project:

SSI-8.1 Exterior Noise Level Standards. Require new development projects to be designed and constructed to meet acceptable exterior noise level standards (see Table SSI-1 [of the General Plan]), as follows:
• Apply a maximum exterior noise level of 60 dBA Ldn in residential areas where outdoor use is a major consideration (e.g., backyards in single-family housing developments and recreation areas in multi-family housing projects). Where the City determines that providing an Ldn of 60 dBA or lower cannot be achieved after the application of reasonable and feasible mitigation, an Ldn of 65 dBA may be permitted.
• Indoor noise levels should not exceed an Ldn of 45 dBA in new residential housing units.
• Noise levels in new residential development exposed to an exterior Ldn 60 dBA or greater should be limited to a maximum instantaneous noise level (e.g., trucks on busy streets, train warning whistles) in bedrooms of 50 dBA.

Maximum instantaneous noise levels in all other habitable rooms should not exceed 55 dBA. The maximum outdoor noise level for new residences near the railroad shall be 70 dBA Ldn, recognizing that train noise is characterized by relatively few loud events.

SSI-8.2 Impact Evaluation. The impact of a proposed development project on existing land uses should be evaluated in terms of the potential for adverse community response based on significant increase in existing noise levels, regardless of compatibility guidelines.

SSI-8.5 Traffic Noise Level Standards. Consider noise level increases resulting from traffic associated with new projects significant if: a) the noise level increase is 5 dBA Ldn or greater, with a future noise level of less than 60 dBA Ldn, or b) the noise level increase is 3 dBA Ldn or greater, with a future noise level of 60 dBA Ldn or greater.

SSI-8.6 Stationary Noise Level Standards. Consider noise levels produced by stationary noise sources associated with new projects significant if they substantially exceed existing ambient noise levels.

SSI-8.7 Other Noise Sources. Consider noise levels produced by other noise sources (such as ballfields) significant if an acoustical study demonstrates they would substantially exceed ambient noise levels.

SSI-8.9 Site Planning and Design. Require attention to site planning and design techniques other than sound walls to reduce noise impacts, including: a) installing earth berms, b) increasing the distance between the noise source and the receiver, c) using non-sensitive structures such as parking lots, utility areas, and garages to shield noise-sensitive areas, d) orienting buildings to shield outdoor spaces from the noise source, and e) minimizing the noise at its source.

In addition to the policies listed above, Section 18.76.090 (Noise) of the City’s Municipal Code contains maximum noise levels for non-transportation noise sources. The City’s quantitative exterior noise standards are reproduced below in Table 8. According to City staff, such standards are interpreted as being hourly average noise level standards (Leq).

Furthermore, Section 8.28.040.D of the Morgan Hill Municipal Code, limits construction activity noise as follows:
"Construction activities" are defined as including but not limited to excavation, grading, paving, demolition, construction, alteration or repair of any building, site, street or highway, delivery or removal of construction material to a site, or movement of construction materials on a site.

Construction activities are prohibited other than between the hours of seven a.m. and eight p.m., Monday through Friday and between the hours of nine a.m. to six p.m. on Saturday. Construction activities may not occur on Sundays or federal holidays. No third person, including but not limited to landowners, construction company owners, contractors, subcontractors, or employers, shall permit or allow any person working on construction activities which are under their ownership, control or direction to violate this provision.

The Gates Project

86 October 2022
Construction activities may occur in the following cases without violation of this provision:
a. In the event of urgent necessity in the interests of the public health and safety, and then only with a permit from the Chief Building Official, which permit may be granted for a period of not to exceed three days or less while the emergency continues, and which permit may be renewed for periods of three days or less while the emergency continues.
b. If the Chief Building Official determines that the public health and safety will not be impaired by the construction activities between the hours of eight p.m. and seven a.m., and that loss or inconvenience would result to any party in interest, the Chief Building Official may grant permission for such work to be done between the hours of eight p.m. and seven a.m. upon an application being made at the time the permit for the work is issued or during the progress of the work.
c. The City Council finds that construction by the resident of a single residence does not have the same magnitude or frequency of noise impacts as a larger construction project. Therefore, the resident of a single residence may perform construction activities on that home during the hours in this subsection, as well as on Sundays and federal holidays from nine a.m. to six p.m., provided that such activities are limited to the improvement or maintenance undertaken by the resident on a personal basis.
d. Public Work projects are exempt from this section and the Public Works Director shall determine the hours of construction for public works projects.

Project Construction Noise
During construction of the proposed project, heavy-duty equipment would be used for demolition, grading, excavation, paving, and building construction, which would result in temporary noise level increases while in operation. Noise levels would vary depending on the type of equipment used, how the equipment is operated, and how well the equipment is maintained. In addition, noise exposure at any single point outside the project site would vary depending on the proximity of construction activities to that point. Standard construction equipment, such as graders, backhoes, loaders, and haul trucks would be used on-site.

Table 9 shows maximum noise levels associated with typical construction equipment.

Based on the table, activities involved in typical construction would generate maximum noise levels up to 85 dB at a distance of 50 feet. As one increases the distance between equipment, or increases separation of areas with simultaneous construction activity, dispersion and distance attenuation reduce the effects of combining separate noise sources. The noise levels from a source decrease at a rate of approximately 6 dB per every doubling of distance from the noise source.

The nearest noise-sensitive receptor is located approximately 140 feet from the project site boundary. Thus, construction activities associated with the proposed project would be less than the levels shown in Table 9 at the receptor.

Regardless, the Morgan Hill Municipal Code does not specify any short-term noise level limits. In addition, Chapter 8.28 of the Morgan Hill Municipal Code prohibits construction activities between 8:00 PM and 7:00 AM, Monday through Friday, and between 6:00 PM and 9:00 AM on Saturdays. Construction activities may not occur on Sundays or federal holidays. Furthermore, construction activities related to the proposed project would include the use of sound-dampening equipment such as mufflers, air-inlet silencers, shrouds, shields, or other noise-reducing features where appropriate.

Enforcement of time restrictions specified in the Morgan Hill Noise Ordinance and the use of noise-dampened equipment would be required to ensure that the temporary or periodic increase in ambient noise levels in the project vicinity associated with construction of the proposed project would not be considered substantial.

Project Operational Noise
The primary noise source associated with operation of the proposed project would be traffic noise. Per General Plan Policy SSI-8.5, noise level increases resulting from traffic associated with new projects are considered significant if: a) the noise level increase is 5 dBA Ldn or greater, with a future noise level of less than 60 dB Ldn, or b) the noise level increase is 3 dB Ldn or greater, with a future noise level of 60 dB Ldn or greater. As shown in Table 7, noise levels 100 feet from Monterey Road were measured to be 68 dB Ldn.

Therefore, the applicable threshold is 3 dB Ldn.

According to the Trip Generation and Operations Analysis prepared for the proposed project by Hexagon, the project is anticipated to generate 55 new vehicle trips during the AM peak hour and 84 new vehicle trips during the PM peak hour. Based on the Exterior Noise and Façade Acoustical Analysis, the project’s increase in peak hour traffic represents a one to three percent increase for each intersection, which would result in an increase in overall traffic noise levels of 0.1 dB, which is indistinguishable to the human ear. As such, ADT produced by the proposed project would not be significant enough to generate an increase in sound levels beyond the City’s 3 dB Ldn threshold. Therefore, traffic noise level increases attributable to the proposed project would be less than significant.

Noise at Proposed Development
Impacts of the environment on a project (as opposed to impacts of a project on the environment) are beyond the scope of required CEQA review. “[T]he purpose of an EIR is to identify the significant effects of a project on the environment, not the significant effects of the environment on the project.” (Ballona Wetlands Land Trust v. City of Los Angeles, (2011) 201 Cal.App.4th 455, 473 (Ballona)). The California Supreme Court recently held that “CEQA does not generally require an agency to consider the effects of existing environmental conditions on a proposed project’s future users or residents. What CEQA does mandate… is an analysis of how a project might exacerbate existing environmental hazards.” (California Building Industry Assn. v. Bay Area Air Quality Management Dist. (2015) 62 Cal.4th 369, 392; see also Mission Bay Alliance v. Office of Community Investment & Infrastructure (2016) 6 Cal.App.5th 160, 197 [“identifying the effects on the project and its users of locating the project in a particular environmental setting is neither consistent with CEQA's legislative purpose nor required by the CEQA statutes”], quoting Ballona, supra, 201 Cal.App.4th at p. 474.)
Based on the above, for the purposes of the CEQA analysis, the relevant inquiry is not whether future residents, workers, and guests at the proposed project will be exposed to preexisting environmental noise-related hazards, but instead whether project-generated noise will exacerbate the pre-existing conditions. However, an evaluation of estimated noise levels at the exterior and interior of the proposed buildings is provided herein for informational purposes and project conditions of approval. The following discussion is based on an Exterior Noise and Façade Acoustical Analysis (Acoustical Analysis) prepared for the proposed project by Veneklasen Associates (see Appendix G).36 As noted previously, ambient noise levels at the project site are defined primarily by traffic noise along Monterey Road and train activity associated with the adjacent UPRR tracks.

Veneklasen calculated the noise exposure levels in different zones across the project site (see Figure 15). The predicted sound levels at each zone are listed in Table 10 below.

Pursuant to the City’s General Plan and Municipal Code (see Table 8), the maximum allowable exterior noise level for residential land uses is 60 dBA Ldn. However, the maximum outdoor noise level for new residences located near the railroad is 70 dBA Ldn.

As presented in Table 10, the predicted noise levels at the proposed project would exceed the allowable noise standard. In order to address the noise standard exceedance, the proposed project would be designed in accordance with the following recommendations provided by Veneklasen, compliance with which would be ensured as a condition of project approval.

• The proposed project shall include upgraded wall assemblies and high Sound Transmission Class (STC)-rated glazing consistent with the requirements presented in Table 11, below.

Additionally, because the windows and doors must be kept closed to meet the noise requirements, mechanical or other means of ventilation may be required for units in Zones A, B, and C. With implementation of the recommendations presented in the Acoustical Analysis, all proposed buildings would comply with the applicable exterior residential building standard of 70 dBA Ldn and interior sound level of 45 dBA Ldn.

Conclusion
Based on the above, operation of the proposed project would not result in the generation of a substantial permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the City’s General Plan and the Municipal Code.

However, considering the potential for construction activities to conflict with standards established by Section 8.28.040 (Enumeration of unlawful noises) of the City’s Municipal Code, the proposed project could result in a potentially significant impact related to temporary increases in ambient noise levels in the project area.

Mitigation Measure(s)
Implementation of the following mitigation measures would reduce the above impact to a less-than-significant level.

XIII-1. Noise-generating construction activities associated with the proposed project shall only occur within the hours identified in Municipal Code Section 8.28.040(D). The above language shall be included on final project improvement plans prior to issuance of a grading permit by the City of Morgan Hill Development Services Department.

XIII-2. To the maximum extent practical, the following measures shall be implemented during project construction:
• All noise-producing project equipment and vehicles using internalcombustion engines shall be equipped with manufacturersrecommended mufflers and be maintained in good working condition;
• All mobile or fixed noise-producing equipment used on the project site that are regulated for noise output by a federal, State, or local agency shall comply with such regulations while in the course of project construction;
• Electrically powered equipment shall be used instead of pneumatic or internal-combustion-powered equipment, where feasible; • Material stockpiles and mobile equipment staging, parking, and maintenance areas shall be located as far as practicable from noise-sensitive receptors;
• Project area and site access road speed limits shall be established and enforced during the construction period; and

• Nearby residences shall be notified of construction schedules so that arrangements can be made, if desired, to limit their exposure to short-term increases in ambient noise levels.

The above requirements shall be included via notation on project grading plans, subject to review and approval by the Development Services Department prior to issuance of a grading permit.
b. Similar to noise, vibration involves a source, a transmission path, and a receiver. However, noise is generally considered to be pressure waves transmitted through air, whereas vibration usually consists of the excitation of a structure or surface. As with noise, vibration consists of an amplitude and frequency. A person’s perception to the vibration depends on their individual sensitivity to vibration, as well as the amplitude and frequency of the source and the response of the system which is vibrating.

Vibration is measured in terms of acceleration, velocity, or displacement. A common practice is to monitor vibration in terms of peak particle velocities (PPV) in inches per second (in/sec). Standards pertaining to perception as well as damage to structures have been developed for vibration levels defined in terms of PPV.

Human and structural response to different vibration levels is influenced by a number of factors, including ground type, distance between source and receptor, duration, and the number of perceived vibration events. Table 12, which was developed by Caltrans, shows the vibration levels that would normally be required to result in damage to structures. As shown in the table, the threshold for architectural damage to structures is 0.20 in/sec PPV and continuous vibrations of 0.10 in/sec PPV, or greater, would likely cause annoyance to sensitive receptors.

The proposed project would only cause elevated vibration levels during construction, as the proposed project would not involve any uses or operations that would generate substantial groundborne vibration.

The primary vibration-generating activities associated with the proposed project would occur during grading, paving, placement of utilities, and construction of foundations. Table 13 shows the typical vibration levels produced by construction equipment at various distances. The most substantial source of groundborne vibrations associated with project construction would be the use of vibratory compactors. Use of vibratory compactors/rollers could potentially be required during construction of the proposed drive aisles.

However, as presented in the table, when construction occurs at 50 feet away from the receiving property, vibration levels would not exceed the 0.2 in/sec PPV threshold for damage to buildings or the 0.1 in/sec PPV threshold for annoyance to receptors. Given that the nearest sensitive receptor is located approximately 140 feet away, vibration impacts would not occur. Additionally, groundborne vibration associated with construction activities would occur intermittently over a short period of time.

It is noted that the Acoustical Analysis prepared for the proposed project also evaluated the vibration levels at the proposed residences due to the train passing. The railroadinduced vibration levels at the project site would be below the 80 VdB guidelines for acceptability as established by the Federal Transit Administration (FTA) and, as a result, further recommendations to reduce vibration levels are not required.

Based on the above, implementation of the proposed project would not expose people to or generate excessive groundborne vibration or groundborne noise levels, and impacts would be less than significant.

Discussion
a. The timing, type, and amount of residential growth in Morgan Hill has historically been controlled by the City’s Residential Development Control System (RDCS) which was adopted for the purpose of managing growth in Morgan Hill. Measure S was approved by the Morgan Hill voters in 2016, extending the City’s RDCS to 2035, and establishing a City population ceiling of 58,200. On January 1, 2020, the City’s RDCS was suspended by SB 330, the Housing Crisis Act of 2019 (Housing Accountability Act), for five years, and thereafter State law extended the Act for an additional five years under SB 8. The Housing Accountability Act prohibits a local agency from placing a cap on the number of housing units that can be approved or constructed either annually or for some other time period or limits the population of the jurisdiction.

The 2035 General Plan planned for commercial development to be constructed on the project site pursuant to the site’s General Plan land use designation of Commercial. The proposed project would develop five commercial flex units and 49 townhome-style condominium units, which provides residential development not anticipated for the site by the General Plan EIR. Using a persons per household rate of 3.09 as estimated by the ABAG 2035 Demographic Projections for the City of Morgan Hill, the proposed project could be expected to house approximately 152 residents.

Population growth itself does not constitute an environmental impact; rather, increased demands on the physical environment resulting from increases in population are considered environmental impacts. For example, increased demands on City services could require system upgrades, the construction of which could have environmental impacts. Physical environmental effects associated with development of the proposed project are evaluated throughout this IS/MND. As discussed in Section XV, Public Services, of this IS/MND, the project site is located in an urban area and is surrounded by existing development. Therefore, construction of new or expanded public services facilities would not be necessary to serve the proposed project. As discussed in Section XIX, Utilities and Service Systems, the proposed project would not include construction of new off-site utility infrastructure or expansion of existing utilities.

While the proposed project would result in population growth, such growth could be accommodated by existing public services and infrastructure and would not result in significant adverse environmental effects. Thus, a less-than-significant impact would occur related to inducing substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (e.g., through projects in an undeveloped area or extension of major infrastructure).

Discussion
a-c,e. The City of Morgan Hill contracts with CAL FIRE (California Department of Forestry and Fire Protection) for fire protection services. Three CAL FIRE stations are located within the City boundaries: El Toro Station, located at 18300 Old Monterey Road; Dunne-Hill Station, located at 2100 Dunne Avenue; and the CAL FIRE station at 15670 Monterey Road. The nearest fire station (El Toro Station) is located adjacent to the project site, separated by the UPRR railroad tracks to the south. Although the City has not adopted response time standards or goals related to fire suppression, CAL FIRE is held to a seven minute, 59 second response time standard pursuant to the 911 Emergency Medical Services Provider Agreement between the City of Morgan Hill and the County of Santa Clara Emergency Medical Services Agency.38
The project site has been previously anticipated by the General Plan for urban development. The increase in demand associated with the proposed project would not necessitate new or physically altered facilities and, due to its proximity to the nearest fire station, the emergency medical services (EMS) response time standard of seven minutes, 59 seconds could be maintained. In addition, the proposed structures would be equipped with fire sprinklers and fire alarm systems. Such features would help to address fire situations within the site, which would reduce the demand for fire protection services from the project site.

The project site is located within the Morgan Hill Police Department’s normal patrol routes, and, thus, police response times would be comparable to nearby existing developments.

Furthermore, the project would provide approximately 152 additional residents (49 units x

3.09 persons per household = 152 residents) in the City of Morgan Hill.39 As such, the incremental increase in demand for police and fire protection associated with the proposed project would not necessitate new or physically altered protection facilities and would not be substantial enough such that the current response times could not be maintained.

In addition, pursuant to Municipal Code 3.56.030, the project applicant would also be subject to developmental impact fees which would finance the cost of public facilities and improvements, including public safety facilities, required by new development. 38 Dwight Good, Assistant Chief Cooperative Fire Protection, Morgan Hill Fire Department.

The Morgan Hill Unified School District (MHUSD) operates public education facilities that serve the project site and surrounding area. The City of Morgan Hill is served by eight elementary schools, two middle schools, two high schools, one continuation school, one K-8 home school program, and one community adult school. Utilizing the MHUSD student yield rate of 0.465 students per household, the total anticipated development potential for the project site (49 residential units) could add approximately 23 new students to MHUSD schools.

The City collects development impact fees to help pay for public services including public schools. Proposition 1A/SB 50 prohibits local agencies from using the inadequacy of school facilities as a basis for denying or conditioning approvals of any “legislative or adjudicative act involving the planning, use, or development of real property.” (Government Code 65996(b).) Satisfaction of the Proposition 1A/SB 50 statutory requirements by a developer is deemed to be “full and complete mitigation.” Therefore, according to SB 50, the payment of the necessary school impact fees for the project would be full and satisfactory CEQA mitigation.

With regard to other public facilities, such as libraries, given the relatively small number of units included in the proposed project, the project would not be anticipated to result in a substantial increase in demand for library services, or other public facilities, such that expanded facilities would be required. Future residents of the proposed project would have access to the Morgan Hill Library, which is operated by the Santa Clara County Library District. In addition, the General Plan EIR concluded that buildout of the City, including the project site, would have a less-than-significant impact related to libraries.

Based on the above, the project would have a less-than-significant impact with respect to creating adverse physical environmental impacts associated with the provision of new or physically altered governmental facilities in order to maintain acceptable service ratios, response times or other performance objectives for fire protection, police protection, and schools.
d. The proposed project is anticipated to generate an estimated 152 additional residents (49 units X 3.09 persons per household = 152 residents) in the City of Morgan Hill.40 As required by Section 3.56.030 of the Morgan Hill Municipal Code, the City collects park impact fees to offset the demand for neighborhood parkland created by new housing developments. In addition, the proposed project would include multiple open space/common areas as an amenity for future residents. Amenities to be included within the common space areas would include, but not be limited to, a children’s play area, bocce ball courts, seating plaza, and barbecue areas. Given that the proposed project would be required to comply with Section 3.56.030 and 17.28.070 of the Municipal Code, and the project would provide a range of on-site recreational amenities, the project would have a less-than-significant impact with respect to creating adverse physical environmental impacts associated with the provision of new or physically altered governmental facilities in order to maintain acceptable service ratios, response times or other performance objectives for parks.

a,b. Considering the total of 49 residential units, the proposed project would generate approximately 152 additional residents (based on 3.09 persons per household) in the City of Morgan Hill.41 Given the City’s parkland goal of five acres per 1,000 residents, the proposed project would create the need for a minor amount of additional parkland (0.76 acres). The City of Morgan Hill has adopted a Land Dedications and Reservations Ordinance (Municipal Code Chapter 17.28) that requires residential developers to dedicate public parkland or pay in-lieu fees, or both, to offset the demand for neighborhood parkland created by their housing developments. If there is no park or recreational facility designated in the City’s Bikeways, Trails, Parks and Recreation Master Plan to be located in whole or in part within the proposed project site to serve the immediate and future needs of the residents, the project applicant shall pay a fee equal to the value of the land prescribed for dedication per Section 17.28.060 of the Municipal Code. The project is not located in whole or in part of a recreational facility identified in the Master Plan; therefore, the project is not proposing to dedicate any land to the City for recreational facilities. The project applicant would pay in-lieu fees required per the Municipal Code. The park impact fees imposed by the City will generate revenue to acquire necessary land to develop new parks or rehabilitate existing neighborhood parks and recreation facilities reasonably related to serve the subdivision. In addition, while the proposed project would not provide any public parkland on-site, the project would include on-site open space/common areas as an amenity for future residents. Based on the above, a less-than-significant impact would occur with regard to recreational resources.

Discussion
a. The law has changed with respect to how transportation-related impacts may be addressed under CEQA. Traditionally, lead agencies used level of service (LOS) to assess the significance of such impacts, with greater levels of congestion considered to be more significant than lesser levels. Enacted as part of SB 743 (2013), PRC Section 21099, subdivision (b)(1), directed the Governor’s Office of Planning and Research (OPR) to prepare, develop, and transmit to the Secretary of the Natural Resources Agency for certification and adoption proposed CEQA Guidelines addressing “criteria for determining the significance of transportation impacts of projects within transit priority areas. Those criteria shall promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses.” Pursuant to SB 743, the Natural Resources Agency promulgated CEQA Guidelines Section 15064.3 in late 2018. It became effective in early 2019. Subdivision (a) of that section provides that “[g]enerally, vehicle miles traveled is the most appropriate measure of transportation impacts. For the purposes of this section, ‘vehicle miles traveled’ refers to the amount and distance of automobile travel attributable to a project. Other relevant considerations may include the effects of the project on transit and non-motorized travel.

Except as provided in subdivision (b)(2) below (regarding roadway capacity), a project’s effect on automobile delay shall not constitute a significant environmental impact.” Please refer to Question ‘b’ for a discussion of VMT.

Pedestrian, Bicycle, and Transit Facilities
In the vicinity of the project site, are provided along the following roadway segments:
southbound Monterey Road, between Cochrane Road and 420 feet south of Cochrane Road; northbound Monterey Road, until 450 feet north of Cochrane Road; Westbound Cochrane Road, between Cochrane Circle and Monterey Road; and eastbound Cochrane Road, east of Monterey Road. The proposed project would provide a new sidewalk along the project frontage on Monterey Road, connecting to existing sidewalks to the north along the adjacent commercial plaza. In addition, the signalized intersection of Monterey Road and Old Monterey Road currently has a crosswalk across the south approach, providing a connection between sidewalks on both sides of Monterey Road, and the Monterey Road and Cochrane Road intersection provides crosswalks across all four legs. Such pedestrian facilities would provide a pedestrian connection between the project site and nearby land uses along Monterey Road. Thus, the proposed project would not conflict with any existing or planned pedestrian facilities and would provide for improved pedestrian connectivity in the project area.

October 2022
Bike lanes are currently provided along the length of Monterey Road, including along the project frontage, and Cochrane Road. With development of the proposed project, the existing bike lane along the Monterey Road frontage would be retained. The project is not expected to generate a significant amount of new bicycle trips. The demand generated by the proposed project could be accommodated by the existing bicycle facilities in the vicinity of the project site. Thus, the proposed project would not conflict with any existing or planned bicycle facilities and sufficient bicycle facilities would be available for future project residents, workers, and guests.

The project site is served by VTA bus routes that run along Monterey Road, Cochrane Road and Hale Avenue. Express Route 568 serves bus stops at the intersection of Cochrane Road and Cochrane Circle, approximately 1,000 feet walking distance from the project site. Frequent Route 68 serves bus stops at the intersection of Hale Avenue and Llagas Road, an approximately 0.8-mile walking distance from the project site; and Local Route 87 serve bus stops at the intersection of Cochrane Road and Cochrane Circle, approximately 1,000 feet walking distance from the project site. A typical mode split in Morgan Hill would be a three percent transit share. Assuming up to three percent transit mode share for the proposed project, the project would generate approximately three transit riders or less during the AM and PM peak hours. The transit ridership demands of the proposed project would not justify the enhancement of any existing transit facilities.

Overall, the proposed project would not have a substantial adverse effect on transit facilities in the project area.

Conclusion
Based on the above, a less-than-significant impact would occur related to conflicting with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities.
b. Section 15064.3 of the CEQA Guidelines provides specific considerations for evaluating a project’s transportation impacts. Pursuant to Section 15064.3, analysis of VMT attributable to a project is the most appropriate measure of transportation impacts, with other relevant considerations consisting of the effects of the project on transit and nonmotorized travel.

Pursuant to Section 15064.3(b)(3), a lead agency may analyze a project’s VMT qualitatively based on the availability of transit, proximity to destinations, etc. Hexagon Transportation Consultants, Inc. prepared a VMT assessment for the proposed project (see Appendix H).42 The City of Morgan Hill, at the time of the VMT report prepared for the proposed project, is undertaking a process of updating its General Plan policies to incorporate VMT methodologies and significance thresholds to be consistent with SB 743, but has not yet released draft thresholds. In the absence of an adopted or draft City policy with numeric thresholds, the VMT assessment relies on The Technical Advisory on Evaluating Transportation Impacts in CEQA published by the Governor’s OPR,43 as well as the VTA VMT Evaluation Tool, to analyze the project’s effects on VMT. The OPR recommendations include the screening thresholds criteria listed below:
42 Hexagon Transportation Consultants, Inc. VMT Assessment for the Proposed The Gates Mixed-Use Development in Morgan Hill, California. July 1, 2022. 43 Governor’s Office of Planning and Research. Technical Advisory on Evaluation Transportation Impacts in CEQA. December 2018.

• Office or residential projects not exceeding a level of 15 percent below existing VMT per capita may indicate a less-than-significant impact on VMT; • Projects (including office, residential, retail, and mixed-use developments) proposed within half a mile of an existing major transit stop or within a quarter of an existing stop along a high-quality transit corridor may be presumed to have a less-thansignificant impact; • 100 percent affordable residential development in infill locations be presumed to have a less-than-significant impact on VMT;
• Projects that generate or attract fewer than 110 trips per day generally may be assumed to cause a less-than-significant impact; and
• Local-serving retail developments (considered to be less than 50,000 square feet in size).

In accordance with the OPR Technical Advisory, VMT per capita is the recommended metric to evaluate CEQA-related transportation impacts for residential land uses. OPR recommends an impact threshold of 15 percent below the existing VMT levels for residential land uses.

In order to assess project VMT associated with the residential portion of the project, the VTA Evaluation Tool was used. The VTA evaluation tool calculates the project VMT based on the project location, type of development, project description, and proposed trip reduction measures. Projects located in areas where the existing VMT is above the established threshold are referred to as being in “high-VMT areas.” Projects in high-VMT areas are required to include a set of VMT reduction measures that would reduce the project VMT to the greatest extent possible.

The VTA’s Evaluation Tool indicates that the City-wide VMT per capita is currently 24.64.

Therefore, the OPR-recommended impact threshold of 15 percent below the citywide average VMT per capita equates to 20.94 VMT per capita. The VTA Evaluation Tool determined that the VMT value resulting from buildout of the proposed project would be

19.4 VMT per capita. Therefore, the VMT per capita of the proposed project would be below the OPR’s recommended impact threshold of 20.94 VMT per capita, and, thus, can be assumed to be less than significant.

In addition, the project’s retail component consists of 4,016 square feetof ground-floor retail space. Because the proposed retail use would be less than 50,000 sf in size, the retail use may be presumed to be a local-serving facility and would, therefore, have a lessthan-significant impact on VMT. The OPR guidelines suggest that by adding retail opportunities into the urban fabric and thereby improving retail destination proximity, local serving retail development tends to shorten trips and reduce VMT. As a result of the project having trip making characteristics of a local-serving retail facility, the presumption can be made that the retail component of the project would have a less-than-significant impact on VMT.

Based on the above, the proposed project would not conflict or be inconsistent with CEQA Guidelines Section 15064.3(b), and a less-than-significant would occur. c,d. Primary site access would be provided by way of a right-in and right-out access driveway on southbound Monterey Road. Inbound and outbound left-turns to and from the project driveway would be prohibited by the existing landscaped median along Monterey Road

between Cochrane Road and Jarvis Drive. Additional site access would be provided by internal roadways connecting to the commercial center to the north, and would be accessible by way of the west leg of the signalized Monterey Road/Cochrane Road intersection. Pursuant to the Trip Generation and Operations Analysis prepared for the proposed project, a total of 55 vehicle trips (20 inbound and 35 outbound) are expected during the AM peak hour and 92 vehicle trips (53 inbound and 39 outbound) are expected during the PM peak hour.44 Due to limited access operations at the Monterey Road driveway, significant vehicle delay and queuing are not expected to occur.

The City’s Design Standards specify a minimum driveway width of 16 feet for residential uses and a maximum driveway width of 36 for commercial uses. As the site plan indicates that the project driveway would be 26 feet wide, the width of the proposed Monterey Road driveway would meet City standards. Furthermore, the project would include the widening of Monterey Road and improvements along the Monterey Road frontage.

According to the Trip Generation and Operations Analysis, Monterey Road has a posted speed limit of 35 mph. For a design speed of 35 mph, the recommended Caltrans stopping sight distance is 250 feet. Vehicles exiting the project site driveway would have sight distance of more than 250 feet to the north along southbound Monterey Road and would be free and clear of any obstructions that would inhibit adequate sight distance.

The proposed circulation system would be designed consistent with applicable City of Morgan Hill design standards and would provide adequate width and turn radii at and along all drive/parking aisles to allow for two-way circulation, including circulation of larger vehicles such as emergency trucks, garbage trucks, and delivery trucks. While the project would include several dead-end drive aisles, emergency vehicles would have sufficient maneuvering space to turn around before exiting the site without encountering obstructions. Given compliance with required roadway design standards, adequate emergency vehicle access would be provided at the project site.

Based on the above, the proposed project would not substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment), and would not result in inadequate emergency access. Therefore, a less-than-significant impact would occur. 44 Hexagon Transportation Consultations, Inc.

   
Discussion
a,b. As discussed in Section V, Cultural Resources, of this IS/MND, the project site has been subject to past disturbance, including regular disking and mowing associated with fuel reduction. Additionally, the site is surrounded by existing residential, commercial, and planned-unit development. Furthermore, archival research by ARM revealed that previously recorded archaeological resources are not located within the proposed project area. However, three previously recorded resources are located within a one-quarter mile radius of the project site, and thus, the Northwest Information Center of the CHRIS noted that the property has potential to contain previously unrecorded archaeological resources.

Nonetheless, in the event that unknown tribal cultural resources are unearthed, consistent with Section 18.60.090 of the City’s Municipal Code, the City standard conditions of approval, as discussed in Section V, Cultural Resources, of this IS/MND, would be implemented.

It should be noted that in compliance with AB 52 (PRC Section 21080.3.1), and SB 18, project notification letters were distributed to a consultation list of tribes with traditional lands or cultural places located within the project area, as identified by the Native American Heritage Commission (NAHC), on May 11, 2022. One response was received from the Tamien Nation. The tribe shared concern over the potentially sensitive area, and requested specific measures be taken in the event that archeological resources are found on-site. In addition, the tribe requested a copy of all reports referenced in the Archival Review. The City confirmed that the City’s Conditions of Approval are still sufficient to the Tamien Nation, and forwarded the reports referenced in the Archival Review, as requested. As such, consultation was deemed complete.

Based on the above, the proposed project is not expected to adversely impact tribal cultural resources. In addition, the project applicant would be required to comply with the City’s standard conditions of approval consistent with Section 18.60.090 of the Morgan Hill Municipal Code. Therefore, a less-than-significant impact to tribal cultural resources would occur.

Water
The City of Morgan Hill provides potable water service to its residential, commercial, industrial, and institutional customers within the City limits. The City’s water system facilities include 14 groundwater wells, 10 potable water storage tanks, 10 booster stations, and over 160 miles of pressured pipes ranging from two to 14 inches in diameter.

The City’s water distribution system meets the needs of existing customers. The City has planned and constructed water projects in conjunction with new street construction in anticipation of future growth and water needs. The City of Morgan Hill has adopted the 2020 Urban Water Management Plan (UWMP), which analyzes the City’s water supply and demand.

Table 14 presents the potable water supply and demand for a single dry year and multiple dry years for the City of Morgan Hill. Even after a three-year drought period, it is estimated that a surplus of 6,957 acre-feet of water would be available. Thus, according to the City’s UWMP, the projected water supply exceeds the water demand for normal, single-dry, and multiple-dry years until at least 2045.45

While the proposed project would require a General Plan Amendment and Rezone, the site is currently designated for commercial use. Therefore, development of the site with urban uses has been generally anticipated by the City. Given the surplus of water that is anticipated within the UWMP, the type and intensity of growth that would be induced by a MU-F General Plan Amendment would not exceed the project site’s associated water use such that the City would not have sufficient water supplies to serve the proposed development.

Therefore, the proposed project would not require or result in the construction of new water treatment facilities or expansion of existing facilities, and sufficient water supplies would be available to serve the project from existing entitlements and resources.

Wastewater
The City of Morgan Hill sewer collection system consists of approximately 160 miles of gravity sewers, over 3,000 manholes, nearly 3 miles of force mains, and 14 lift stations.

The sewer lines range in size from four inches to 30 inches in diameter and the piping system includes 26 siphons. The City’s collection system moves the City’s wastewater south to the South County Regional Wastewater Authority (SCRWA) Wastewater Treatment Facility (WWTF) located in southern Gilroy. SCRWA is a joint powers authority formed by the cities of Morgan Hill and Gilroy to collectively treat the wastewater of both cities.46 The City of Morgan Hill has an allocation of 3.56 million gallons per day (MGD) from the WWTF. The average dry weather flow from the City of Morgan Hill was approximately 2.7 MGD in 2015.47
The proposed project would connect to an existing east to a sewer system located within the project site vicinity. Based on the current and projected sewage flows associated with the WWTF, the incremental increase in wastewater generation associated with the development of the proposed residences and retail space would not require the construction of new or expansion of existing wastewater treatment facilities, as adequate capacity is already sufficient to serve the proposed project. Furthermore, the type and intensity of growth that would be induced by the proposed project has been generally considered in the 2035 General Plan and associated wastewater generation has been 46 City of Morgan Hill.

analyzed in the General Plan EIR. The General Plan EIR determined that impacts related to wastewater treatment capacity would be less than significant.

Stormwater
Issues related to stormwater infrastructure are discussed in Section X, Hydrology and Water Quality, of this IS/MND. As noted therein, the proposed project would not significantly increase stormwater flows into the City’s existing system. The final drainage system design for the project will be subject to review and approval by the City of Morgan Hill City Engineer to confirm that the proposed drainage system for the project is consistent with the City’s Storm Drainage Master Plan and standard stormwater-related conditions of approval. Therefore, the proposed project would not require or result in the construction of new stormwater drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects.

Electricity, Natural Gas, and Telecommunications
Electricity would be provided by PG&E by way of existing electrical infrastructure in the project vicinity. Internet and telephone services would be provided by Frontier Communications, AT&T, Charter Communications, or a similar service provider operating within the City. The project would not require major upgrades to, or extension of, existing infrastructure. Thus, impacts to electricity and telecommunications infrastructure would be less than significant. The City prohibits the use of natural gas infrastructure in all newly constructed buildings, unless the project applicant establishes that it is not physically feasible to construct the building without natural gas infrastructure.

Conclusion
Based on the above, the type and intensity of growth that would be induced by the proposed project was generally considered in the 2035 General Plan and associated wastewater generation and water use has been analyzed in the General Plan EIR. Thus, the increase in water demand and wastewater generation associated with the proposed project would not be considered substantial. In addition, the project is located within a developed urban area and would not require major expansion or extension of existing water, wastewater, electrical, or telecommunications facilities in the project area.

Therefore, the proposed project would not require or result in the relocation or construction of new or expanded water, wastewater treatment, stormwater, electric power, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects. Sufficient water supplies would be available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years. Furthermore, adequate wastewater capacity would be available to serve the project’s projected demand in addition to the SCRWA’s existing commitments. Thus, a less-than-significant impact would occur.

Landfill has a maximum permitted tonnage limit of 3,500 tons per day and a design capacity of 49,700,000 cubic yards.49
While the proposed project would require a General Plan Amendment and Rezone, the site is currently designated for commercial use. Therefore, development of the site with urban uses has been generally anticipated by the City. Considering the relatively small scale of the proposed project, the project would not produce enough solid waste for the landfill to exceed capacity. Thus, sufficient permitted capacity exists at the Monterey Peninsula Landfill and Materials Recovery Facility to accommodate the proposed project’s incremental increase in solid waste disposal needs.

During project construction, as required by CBSC Section 4.408, the proposed project would be required to submit a Waste Management Plan to the City detailing on-site sorting of construction debris. Implementation of the Waste Management Plan would ensure that the proposed project meets established diversion requirements for reused or recycled construction waste.

Based on the above, the proposed project would comply with applicable federal, State, and local statutes and regulations related to solid waste, and a less-than-significant impact would occur related to solid waste.

Discussion
a-d. As discussed in Section IX, Hazards and Hazardous Materials, of this IS/MND, the City’s Wildland Urban Interface map indicates that the project site is not located in a High or Very High FHSZ.50 While the residential area further to the west of the site past Del Monte Avenue is located within a Very High FHSZ, the area was classified as such in 2008, prior to buildout of the area with residential uses. Furthermore, the project site is separated approximately 1.28 miles way from the FHSZ by existing residential development and roadways. The project would be required to comply with all applicable requirements of the California Fire Code, as adopted by Chapter 15.44 of the City’s Municipal Code, including installation of fire sprinkler systems.

As noted in Section IX, implementation of the proposed project would not result in any substantial modifications to the City’s existing roadway system and would not interfere with potential evacuation or response routes used by emergency response teams. The project would not conflict with the City’s Emergency Operations Plan.51 In addition, the project is not located on a substantial slope, and the project area does not include any existing features that would substantially increase fire risk for future residents, workers, or visitors. Given that the project site is located within a developed urban area and is situated adjacent to existing roads, water lines, and other utilities, the project would not result in substantial fire risks related to installation or maintenance of such infrastructure. Lastly, as discussed in Section VII, Geology and Soils, and Section X, Hydrology and Water Quality, of this IS/MND, development of the proposed project would not expose people or structures to significant risks related to flooding or landslides.

Based on the above, the proposed project would not expose people or structures to the risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands, and no impact would occur.

Discussion
b. As discussed in Section IV, Biological Resources, of this IS/MND, the proposed project would be required to implement mitigation measures to minimize potential impacts to burrowing owl and nesting migratory birds and raptors protected by the MBTA. In addition, the site does not contain known historical or cultural resources. Although unlikely, the possibility exists that subsurface excavation of the site during grading and other construction activities could unearth deposits of cultural significance. However, this IS/MND explains how the City’s Municipal Code requires standard measures for development projects that would ensure any impacts to such resources would be less than significant. Therefore, the proposed project’s impact related to degradation of the quality of the environment, substantial reduction of habitat or plant and wildlife species, and elimination of important examples of the major periods of California history or prehistory would be less than significant with mitigation incorporated. c. As discussed in Section XI, Land Use and Planning, of this IS/MND, the proposed project would be consistent with the site’s current MU-F General Plan land use and zoning designations following approval of the proposed General Plan Amendment and Rezone.

As such, the type and intensity of growth that would be induced by the proposed project were generally anticipated in the 2035 General Plan and associated cumulative environmental effects were analyzed in the General Plan EIR. Furthermore, as demonstrated in this IS/MND, all potential environmental impacts that could occur as a result of project implementation would be reduced to a less-than-significant level with implementation of project-specific mitigation measures and compliance with applicable General Plan policies. When viewed in conjunction with other closely related past, present, or reasonably foreseeable future projects, development of the proposed project would not contribute to cumulative impacts in the City of Morgan Hill, and the project’s contribution to the cumulative impact would be less than significant with mitigation incorporated.

d. The project site would be developed in a generally urbanized and built-up area of the City of Morgan Hill. As demonstrated in Section III, Air Quality, Section IX, Hazards and Hazardous Materials, and Section XIII, Noise, development of the proposed project would not be expected to result in substantial adverse impacts to human beings, either directly or indirectly. The potential for substantial environmental effects on human beings is addressed within this IS/MND and all impacts have been identified as less-than-significant or less-than-significant with the incorporation of mitigation measures. As such, the impact would be less than significant with mitigation incorporated.

4 SECTION 1.INTRODUCTION
Johnson Marigot Consulting, LLC (JMC) has been retained to provide a biological constraints analysis for an approximately 4.7-acre property located at 18545 Monterey Road (Accessor Parcel Number (APN) 764-10-013) and 18565 Monterey Road (APN 764-10-015) in the City of Morgan Hill, Santa Clara County, California (Figure 1). It is within the coverage area of the Santa Clara Valley Habitat Plan (SCVHP). The purpose of this report is to qualitatively identify potential occurrences and/or habitat for special-status plant and wildlife species on the site and to identify local, state, and/or federal biological constraints and ordinances applicable to the development of the site. The site is proposed for residential development within the entirety of the parcel boundaries (Attachment 1), and as such, is presumed to include site grading and compaction with removal of existing vegetation within the entirety of the parcel boundaries. The site is located entirely within the Planning Limit of Urban Growth for the City of Morgan Hill, as defined in the SCVHP (Figure 2).

SECTION 2.METHODOLOGY
A literature review was conducted for special-status species known to occur in the vicinity of 18545-18565 Monterey Road. In addition to a literature review, the California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB) and the California Native Plant Society (CNPS) Rare Plant Inventory were queried for occurrences of specialstatus species in the vicinity of the site. A list of these special-status species has been compiled in Table 2, which also discusses listing/ranking status, required habitat components, proximity of records to 18545-18565 Monterey Road, and probability of occurrence within the site.

Additional research was conducted to identify local, state, and federal natural resource ordinances and laws that would be applicable to the development of 18545-18565 Monterey Road; these ordinances and laws are discussed below. It should be noted however that although some local entitlement requirements are addressed below (e.g., The Santa Clara Valley Habitat Plan), this report only summarizes local requirements pertaining to biological resources.

On September 17, 2021, Naomi Schowalter of JMC conducted a site visit to evaluate biological resources present on site. The site assessment included a reconnaissance level survey of 18545-18565 Monterey Road to characterize vegetation, topography, and current and historic uses of the site (as well as the surrounding properties), and to investigate potential presence of waters of the U.S./State. Observations made during site visits were used to determine the potential for the site to provide suitable habitat for special-status species (presence of habitat components necessary to support the species) and sensitive habitats.

5 SECTION 3.EXISTING SITE CONDITIONS
The approximately 4.7-acre property is comprised of two parcels and is located within the city limits of Morgan Hill, Santa Clara County, California (the approximate center of the site is

37.1429042°N, -121.6635127°W) (Figure 1). The roughly triangular site is located south of the intersection of Monterey Road and Jarvis Drive (Figure 1). The western boundary abuts an elevated railroad track, the eastern boundary is Monterey Road, and the northern boundary is a commercial development (gas station and Starbucks Coffee). Topography within the Study Area is flat to gently sloping. Vegetation in the Study Area consists of nonnative annual grassland and seasonal wetland species with scattered native and non-native trees and shrubs, particularly along the edges of the property. Part of the Starbucks Coffee parking lot is within the project boundary. The undeveloped portion of the site is routinely disked and mowed for fuel reduction. Three depressional wetlands, three converging wetland drainage ditches, one stormwater detention basin, and a small patch of cattails associated with the stormwater detention basin are located in the project area (Figure 3). The property historically contained a single drainage ditch constructed in the late 1930s to improve drainage of the adjacent State Highway (now Monterey Road), spanning from three 24-inch culverts near Monterey Road on the eastern side of the property to the railroad tracks on the western side of the property. The other two short lengths of ditch and the stormwater detention basin were constructed in 2004-2005 as part of the commercial development bordering the northern edge of the project area.

3.1 LAND COVER TYPES
Per CDFW’s California Wildlife Habitat Relationships (CWHR) System, the predominant vegetation communities within the Study Area are annual grassland, fresh emergent wetland, and urban (CDFW 2022a). Under the SCVHP, the equivalent land cover types are California annual grassland, seasonal wetlands, and ornamental woodland, respectively (Figure 3).

Additionally, the Starbucks Coffee parking lot is considered urban-suburban land cover under the SCVHP. Herbaceous vegetation dominates the site, and trees and shrubs are primarily evenly spaced along the edges of the property and the detention basin. Vegetation communities on the site are altered due to routine mowing and disking, plantings, and constructed drainage features.

3.1.1 CALIFORNIA ANNUAL GRASSLAND
The California annual grassland vegetation community is most common across the project site. Plant species common throughout this community include oats (Avena sp.), ripgut brome (Bromus diandrus), soft brome (Bromus hordeaceus), and wild radish (Raphanus sp.). The annual grasslands in the project area are routinely mowed or plowed. Coyote brush (Baccharis pilularis) is scattered across the annual grassland.

The SCVHP indicates that this habitat type may constitute habitat components for covered

6 species, including San Joaquin kit fox (Vulpes macrotis mutica), western burrowing owl (Athene cunicularia hypugea), California red-legged frog (Rana draytonii), California tiger salamander (Ambystoma californiense), western pond turtle (Clemmys marmorata), tricolored blackbird (Agelaius tricolor), and Bay checkerspot butterfly (Euphydryas editha bayensis).

None of these species were observed, though California ground squirrel (Spermophilius beecheyi) burrows were found during the September 17 site visit; burrows represent potential nest sites for western burrowing owls.

3.1.2 SEASONAL WETLAND
Seasonal freshwater emergent wetlands cover approximately 0.52 acre of the Study Area. This community is relatively evenly distributed across the site. Plant species common within this vegetation community include seaside barley (Hordeum marinum), English plantain (Plantago lanceolata), rabbitsfoot grass (Polypogon monspeliensis), Italian rye grass (Festua perennis), curly dock (Rumex crispus), tall cypress (Cyperus eragrostis), rough cocklebur (Xanthium stumarium), and stinkwort (Dittrichia graveolens). The SCVHP indicates that this habitat type may constitute habitat components for covered species, including California tiger salamander, California red-legged frog, western pond turtle, western burrowing owl, tricolored blackbird, and San Joaquin kit fox.

3.1.3 ORNAMENTAL WOODLAND
Large established trees and shrubs are present along Monterey Road, the railroad tracks, and the edges of the detention basin, consisting of evenly spaced (i.e., planted) native and nonnative species. Along the railroad tracks, willows (Salix exigua), coast live oak (Quercus agrifolia), valley oak (Quercus lobata), coast redwood (Sequoia sempervirens), and Northern California black walnut (Jugluns hindsii) are present at even intervals. To the east of the detention basin, silver wattle (Acacia dealbata) is present. Along Monterey Road, oleander (Nerium oleander), California black oak (Quercus kelloggii), California sycamore (Platanus racemose), valley oak (Quercus lobata), and deodar cedar (Cedrus deodara). These areas were likely historically described as California annual grasslands but currently meet the definition of “ornamental woodland” within the context of the SCVHP. The SCVHP identifies this habitat type is suitable for many wildlife species including, American robin (Turdus migratorius), mockingbird (Mimus polyglottos), American crow (Corvus brachyrhynchos), and European house sparrow (Passer domesticus). The SCVHP also indicates the potential for lizards and woodrats.

3.2 POTENTIAL WATERS OF THE U.S./STATE
A total of 0.52 acre of potential waters of the U.S./State were mapped in the project area, including six separate wetlands (JMC 2021). These wetlands consist of three interconnected drainage ditches with in-channel wetlands, a stormwater detention basin, three depressional wetlands, and a small wetland located at the detention basin discharge pipe. The U.S. Army Corps of Engineers (USACE) issued an Approved Jurisdictional Determination for the project
