Re: Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001)
Executive Summary and Introduction
The City of Mountain View (City) published the Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments, The Village at San Antonio – Phase III Project (2022 Addendum) as part of the public hearing materials for the Village at San Antonio – Phase III Project (project) at the April 20, 2022 Environmental Planning Commission (EPC) meeting. Subsequent to the preparation and public posting of the 2022 Addendum, there have been minor modifications to the project, including minor modifications to the description of the proposed Project, minor modifications to existing conditions surrounding the project, updates to the California Environmental Quality Act (CEQA) thresholds of significance for climate impacts, and updates to City standard conditions of approval (COAs) and applicable City codes and regulations. This memorandum characterizes these minor changes, as applicable to the CEQA analysis, and assesses the potential for any changes in environmental impacts resulting from the aforementioned modifications, to determine whether the modifications would change the conclusions presented in the 2022 Addendum prepared for the project.
In summary, the preparers of the 2022 Addendum have found there is no substantive change in the 2022 Addendum’s analysis or its conclusion that no supplemental or subsequent EIR is required for the City’s consideration of the project, based on the review provided herein.
Attachment 2
Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
2022 Addendum Overview
The proposed project is located at 365 and 405 San Antonio Road and 2585 and 2595 California Street within the San Antonio Precise Plan (SAPP).1 The project proposes the demolition of two single-story commercial buildings and associated surface parking and the construction of a commercial building with publicly-accessible ground-level pathways and open space along with below-grade parking for building users at the intersection of California Street and San Antonio Road.
On project completion, the total building area would measure approximately 182,352 gross square feet (gsf), including approximately 12,970 gsf of ground floor retail space and approximately 169,382 gsf of office and office support services space.
Included in the SAPP is an office development cap to prioritize residential development and balance office development with future housing growth. The SAPP currently stipulates an areawide maximum of 600,000 square feet of net new office development, with up to 400,000 square feet permitted in the Northwest San Antonio Center Master Plan Area. Office development beyond this cap will require an amendment to the SAPP, which is proposed as part of this project.
As described in Chapter 2, Project Description, of the 2022 Addendum, the proposed amendments to the SAPP allow exceedance of the 400,000-gsf limit on net new office development within the Northwest San Antonio Master Plan, while maintaining the existing 600,000-gsf office development limit in the SAPP as a whole. Furthermore, the project proposes to purchase and utilize 150,000-gsf of transferred development rights from the City’s Los Altos School District (LASD) Transfer of Development Rights (TDR) Program, allowing the project to exceed the applicable 400,000 office development cap. The TDR Program sending site is within the San Antonio Precise Plan and does not change the maximum allowable gsf studied in the San Antonio Precise Plan EIR.
As demonstrated throughout the 2022 Addendum, the proposed project would not result in new significant impacts or increases in the severity of previously identified significant impacts, and would not trigger the need for new or considerably different mitigation measures that were not identified in the certified Final SAPP EIR, thereby rendering a supplemental or subsequent EIR necessary. Since the Final SAPP EIR was certified in December 2014, there have been changes to the background conditions in the Plan Area, and portions of the area have been constructed. However, because the changes are not substantial, the changed circumstances would not require major revisions to the Final EIR. For the foregoing reasons, the 2022 Addendum determined that no supplemental EIR is necessary. Accordingly, as described further in 2022 Addendum, an addendum was the appropriate mechanism for CEQA review of the proposed project.
The SAPP Draft Environmental Impact Report (SAPP EIR) was published in September 2014, and the Final EIR, including responses to comments on the Draft EIR, was published in November 2014. The Final EIR was certified in December 2014. The 2022 Addendum was prepared under California Environmental Quality Act (CEQA) Guidelines Sections 15168(c) and 15164. The 2022 Addendum was recommended for adoption by the EPC on April 20, 2022. The City of Mountain View City
1 The SAPP provides guiding principles, policies, development criteria, and implementation strategies for transforming the existing commercial area into a mixed-use core within a broader residential neighborhood, while maximizing the area’s proximity to transit services and regional roadways.
Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
Council will be the final decisionmaking authority for the proposed project and for adoption of the 2022 Addendum at an upcoming public hearing.
Minor Modifications to the Description of the Proposed
Project
As described below, subsequent to the EPC recommendation that the City Council approve the proposed project and adopt the 2022 Addendum, the project was put on hold and minor modifications were made to the proposed project related to:
• Location of transformers
• ADA/electric vehicle parking spaces for retail-commercial floor area • Construction start date
• Need for a shared parking reduction
The proposed project was modified to shift the underground transformers to an aboveground utility room, adjacent to the originally-proposed underground transformers that had previously been assumed in the 2022 Addendum. The relocation of the transformers to an aboveground utility room would not result in any increase in building area or a reduction in commercial space. The proposed project would still have a total building area of approximately 182,352 gsf, including the approximately 12,970 gsf of retail/commercial space. In addition, the building height would be the same and would not exceed the maximum allowable building height of 95 feet for the site. No other changes are proposed that would affect the building’s façade or appearance. The project has also been revised to provide additional accessible (ADA) and electric vehicle-charging stalls to satisfy updated City Building Code requirements for the project’s ground level retail-commercial area, which was previously exempted through the shared parking reduction that is no longer part of the project pursuant to Senate Bill 2097 implementation. The additional spaces include: three (3) ADA stalls, one (1) electric vehicle (EV) ADA stall and 13 standard EV stalls through improvements to existing spaces within the adjacent shared parking garage.
In addition, the proposed project office parking garage would be required to comply with the current version of the City of Mountain View’s Building Code electric vehicle parking requirements.
The 2022 Addendum assumed 14 percent of the vehicle parking spaces would be designated for electric, clean-air, or vanpool vehicles. Outlets would be provided for recharging electric vehicles.
The proposed project would be modified to comply with the current version of the City of Mountain View’s Building Code electric vehicle parking requirements, which require 45 percent of the vehicle parking spaces would be designated electric vehicle-capable spaces (for electric, clean-air, or vanpool vehicles) of which 35 percent of the EV-capable spaces will be provided with EV supply equipment. Similar to the modifications to the transformers, the modifications related to project parking would not result in any increase in building area or a reduction in commercial space.
Furthermore, the 2022 Addendum assumed construction of the proposed project would begin in February 2022. The proposed project was modified to assume construction would begin in February Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
2027. However, the construction duration, phasing, equipment and other activities would not change compared to what was assumed in the 2022 Addendum.
The proposed project would still require the same approvals and entitlements listed in Section 2.7, Required Permits and Approvals, in Chapter 2, Project Description, of the 2022 Addendum. However, the planned community permit would no longer include a shared parking reduction because Assembly Bill (AB) 2097 has since rescinded the City’s authority to mandate minimum parking requirements, while preserving the City’s ability to require EV and accessible parking spaces.
Evaluation of 2022 Addendum Conclusions
The analysis below consists of a summary of the potential impacts of the proposed project and an evaluation of whether the minor modifications to the description of the proposed project would result in different impacts or changes to any of the conclusions in the 2022 Addendum. This memorandum presents only information that is directly pertinent to the reviewer’s understanding of the modifications to the proposed project and the comparative impact determinations.
Aesthetics, Agricultural Resources, Mineral Resources, and Wildfire. The 2022 Addendum concluded that the proposed project would have no impact related to aesthetics, agricultural resources, mineral resources, or wildfire. The modifications to the proposed project would not change the conclusions in the 2022 Addendum.
Air Quality. The 2022 Addendum determined that the proposed project would not conflict with or obstruct implementation of an air quality plan or result in a cumulatively considerable contribution to criteria pollutants. The impacts would be less than significant. In addition, the 2022 Addendum also determined that any new stationary sources of toxic air contaminants (e.g., boilers, backup diesel generators) operated as part of the proposed project would be subject to Bay Area Air Quality Management District (BAAQMD) permitting requirements. Table 3.1-2 and Table 3.1-3 from the 2022 Addendum show that the proposed project would not expose sensitive receptors to health risks that would exceed BAAQMD-established exposure criteria.
A Multimodal Transportation Analysis (MTA) was performed for the proposed project to assess the project’s consistency with transportation and parking policy and design elements of the SAPP. The MTA is a supplemental transportation analysis that builds upon the SAPP EIR, and was used to help evaluate the potential health effects due to traffic congestion (i.e., mobile source emissions of Carbon Monoxide [CO] from increased traffic volumes at intersections) that may occur with implementation of the proposed project. The MTA determined that the proposed project would not result in a change in level of service or substantially increase average critical delay at any intersection. As such, the proposed project would not exceed the BAAQMD screening criteria for peak-hour intersection vehicle volumes. Therefore, it was determined that traffic generated by the proposed project would not result in, or contribute to, localized carbon dioxide concentrations that would exceed applicable NAAQs or CAAQs. Overall, the 2022 Addendum determined that, with implementation of Mitigation Measure AIR-1 from the SAPP EIR, diesel particulate matter emitted during project construction would not expose sensitive receptors to health risks that would exceed BAAQMD-established criteria. The impacts would be less than significant. Furthermore, the 2022 Addendum determined that the office/commercial and retail land uses developed on the project site would not involve long-term operation of sources with odorous emissions, which would be atypical in an urban environment, or Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
development of any major sources of odors (e.g., a landfill, wastewater treatment plant, dairy). The impacts were determined to be less than significant.
The modifications to the proposed project would shift the underground transformers to an aboveground utility room adjacent to where the underground transformers had previously been proposed, as a result of current requirements by PG&E. In addition, the proposed project has been modified to comply with the current version of the City of Mountain View’s Building Code electric vehicle parking requirements, which have been updated since EPC review and recommendation of the 2022 Addendum. However, these modifications would be minor and would not require a change in the type of construction-related activity or an increase in duration, nor would they result in an increase in building area or reduction in commercial space. The same air quality SAPP EIR mitigation measures and COAs would apply. Additionally, because construction of the proposed project would occur in later years than was assumed in the 2022 Addendum, actual construction emissions and health risk impacts are now likely to be lower. In general, construction equipment and trucks become cleaner (i.e. lower-emitting) as time passes, because fleet turnover results in the transition away from older, higher-emitting vehicles to newer, lower-emitting vehicles. Thus, the later-than-anticipated construction schedule could result in the use of cleaner equipment and trucks involved in the construction of the proposed project relative to the 2022 Addendum and, most likely, lower emissions and health impacts. Therefore, the modifications to the proposed project would likely result in the same or less construction-related air quality and health risk impacts, which would be less than significant with mitigation. Similarly, operational-related emissions would also likely be lower as a result of the delayed construction of the proposed project. The primary source of emissions during operations would be employees commuting to and from the project site, and this source of emissions would also likely be lower in the first years of operation as a result of the ongoing transition to lower-emitting personal vehicles. Operation of the proposed project would thus result in the same or less air quality impacts as previously reported.
Biological Resources. The 2022 Addendum determined that the proposed project would result in the removal of 13 trees on the project site, including five heritage trees. Therefore, the COAs related to biological resources would apply to the proposed project. The less-than-significant impacts related to substantial adverse effects on species identified as candidate, sensitive, or special status; interference with the movement of any native resident or migratory fish or wildlife species; or conflicts with local policies or ordinances protecting biological resources would be the same as those identified in the SAPP EIR. In addition, the proposed project would have no impact on riparian habitat or other sensitive natural communities, state or federally protected wetlands, or an adopted habitat conservation plan (HCP), natural community conservation plan (NCCP), or other approved local, regional, or state HCP. The modifications to the proposed project would not change the characteristics of the project site in terms of the analyzed biological resources; therefore, the modifications to the proposed project would result in less-than-significant impacts on biological resources, consistent with the conclusions identified for the proposed project in the 2022 Addendum.
Cultural Resources. The 2022 Addendum determined that, with application of COAs related to historical, archaeological, and paleontological resources, as well as human remains, the proposed project would result in less-than-significant impacts related to cultural resources. The modifications to the proposed project would not change the characteristics of the project site; therefore, the modifications to the proposed project would result in less-than-significant impacts on cultural Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
resources, consistent with the conclusions identified for the proposed project in the 2022 Addendum.
Geology and Soils. As detailed in the 2022 Addendum, the proposed project would be required to adhere to the City’s permitting requirements, including adherence to the California Building Code and COAs related to seismic risk. Therefore, the proposed project would result in less-than- significant impacts from strong seismic ground shaking, liquefaction and lateral spreading, landslides, soil erosion or loss of topsoil, unstable geologic units or soils, expansive soil, and paleontological resources. In addition, the proposed project would result in no impact from the use of septic tanks or alternative wastewater disposal systems. The modifications to the proposed project would not change the characteristics of the project site; therefore, the modifications to the proposed project would result in less-than-significant impacts related to geology and soils, consistent with the conclusions identified for the proposed project in the 2022 Addendum.
Greenhouse Gas Emissions. The 2022 Addendum determined that, in addition to being consistent with the City’s Greenhouse Gas Reduction Plan, the proposed project’s emissions would be in compliance with applicable regulatory programs as well as applicable greenhouse gas (GHG) emissions reduction strategies. Similar to the discussion for Air Quality, GHG emissions are likely to be lower than assumed in the 2022 Addendum due to the delayed implementation of the proposed project resulting in the use of cleaner construction equipment, trucks, and personal vehicles, for construction and operations, relative to the 2022 Addendum. As such, the proposed project would thus result in the same or less GHG impacts as previously reported in the 2022 Addendum, which were determined to be less than significant.
As discussed previously, the modifications to the proposed project would shift the underground transformers to an aboveground utility room and revise project plans to comply with City Green Building Code requirements. These modifications would be minor and would not require a change in the type of construction-related activity or an increase in duration, nor would they result in an increase in building area or reduction in commercial space. Therefore, the modifications to the proposed project would result in the same less-than-significant impacts related to GHG emissions as the proposed project.
Hazards and Hazardous Materials. As detailed in the 2022 Addendum, the proposed project would be required to adhere to the City’s permitting requirements, the California Building Code, and COAs related to hazardous materials and emergency access routes. Therefore, the proposed project would result in the less-than-significant impacts related to the routine transport, use, or disposal of hazardous materials; reasonably foreseeable upset and accident conditions involving the release of hazardous materials; hazardous materials sites, pursuant to Government Code Section 65962.5; and impairing or interfering with an adopted emergency response plan or emergency evacuation plan. In addition, the proposed project would have no impact related to airports or hazardous emissions near a school.
The modifications to the proposed project would be constructed on the same project site. It would result in no change in construction-related or operational activities, including demolition, excavation, foundation work, and building construction and operation. The modifications to the proposed project would not change the characteristics of the project site; therefore, the modifications to the proposed project would result in less-than-significant impacts related to Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
hazards and hazardous materials, consistent with the conclusions identified for the proposed project in the 2022 Addendum.
Hydrology and Water Quality. As demonstrated in the 2022 Addendum, the proposed project would be required to adhere to the City’s permitting requirements and the COAs related to water quality.
Therefore, the proposed project would result in less-than-significant impacts related to groundwater supplies and recharge, erosion or siltation, stormwater runoff, the capacity of existing or planned stormwater drainage systems, flooding, a release of pollutants due to project inundation, or conflicts with applicable water quality management plans. In addition, the proposed project would result in no impacts related to water quality standards or waste discharge requirements or otherwise substantially degrade surface water or groundwater. The modifications to the proposed project would be constructed on the same project site and under the same hydrological conditions.
No change in construction is proposed, including demolition, excavation, foundation work, and building construction; there would also be no change with respect to retention of the pervious area.
The modifications to the proposed project would not change the characteristics of the project site; therefore, the modifications to the proposed project would result in less-than-significant impacts related to hydrology and water quality, consistent with the conclusions identified for the proposed project in the 2022 Addendum.
Land Use. The modifications to the proposed project would not introduce a new land use that has not already been evaluated in the 2022 Addendum for the proposed project. The modifications to the proposed project would be consistent with applicable plans and policies and therefore result in the same less-than-significant impacts related to land use, plans, and policies as those previously identified for the proposed project.
Noise. As summarized in the 2022 Addendum, the proposed project would not substantially increase traffic noise on off-site sensitive land uses, demolition and construction activity would not result in structural damage to nearby buildings or sleep disturbance at nearby residential land uses, and development of office and retail land uses at the project site would not result in the exposure of people to excessive noise levels from aircraft. The modifications to the proposed project would not require a change in the type of construction-related activity or an increase in duration. The project modifications, including relocation of the building’s transformers and revisions to project plans to comply City Green Building Code requirements, would not affect the building’s backup emergency generator; heating, ventilation, and air-conditioning system; truck activity in loading areas; or traffic on area roadways, nor would the modifications introduce a new noise-sensitive land use to the project site. The same construction-related and operational noise conditions would apply to the modifications to the proposed project. Therefore, the same less-than-significant impacts related to construction noise and operational noise would apply to the modifications to the proposed project.
The modifications to the proposed project would remain consistent with the land use compatibility guidelines for community ambient noise levels.
Population and Housing. As detailed in the 2022 Addendum, the proposed project would not result in any additional unplanned population growth or the displacement of housing or people. The modifications to the proposed project would be developed on the same project site. It would not require a change in the type of construction-related activity or an increase in duration, nor would it result in an increase in building area or reduction in commercial space. Therefore, the modifications Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
to the proposed project would result in the same less-than-significant impacts related to population and housing as previously disclosed for the proposed project.
Public Services and Recreation. As detailed in the 2022 Addendum, the proposed project would comply with standard City practices, including required development impact fees, the provision of open spaces, and general plan policies and COAs related to public services and recreational facilities, ensuring that the proposed project would result in less-than-significant impacts. The modifications to the proposed project would be developed on the same project site. It would not require a change in the type of construction-related activity or an increase in duration, nor would it result in an increase in building area or reduction in commercial space. Therefore, the modifications to the proposed project would result in the same less-than-significant impacts related to public services and recreation as previously disclosed for the proposed project.
Transportation and Traffic. As summarized in the 2022 Addendum, the proposed project would not alter or modify the roadway network surrounding the project site. Therefore, the proposed project would be consistent with adopted plans, ordinances, and policies addressing the safety and performance of the circulation system. It would satisfy the City’s vehicle-miles-traveled screening criteria and would not substantially induce additional automobile traffic. Mitigation Measure TRANS-1 from the SAPP EIR and the City’s Standard COAs related to transportation and circulation, including required preparation of a Traffic Control Plan, would apply to the proposed project.
Therefore, the proposed project would result in less-than-significant impacts related to transportation and traffic.
The modifications to the proposed project would not change the total number of parking spaces to be provided. In addition, the planned community permit would no longer require a shared parking analysis and reduction because AB 2097 rescinded the City's authority to mandate minimum parking requirements, with the exception of requirements for EV and accessible parking spaces. The modifications to the proposed project would not change proposed development on the project site, as the modifications would not result in an increase in building area or reduction in commercial space. Therefore, with implementation of applicable COAs and Mitigation Measure TRANS-1, the modifications to the proposed project would result in the same less-than-significant impacts related to transportation and traffic as previously disclosed for the proposed project.
Utilities and Service Systems. As detailed in the 2022 Addendum, the proposed project would not exceed available water supplies or require new water, wastewater, or stormwater infrastructure beyond the Project’s planned connections to existing water, sewer, and storm drain service mains and laterals. In addition, the proposed project would comply with Mitigation Measures UTL-1, UTL-2, and UTL-3 from the SAPP EIR and COAs pertaining to waste reduction and recycling, green building requirements, sewer and storm drain systems, water and energy efficiency, and stormwater requirements, ensuring that impacts related to utilities and service systems would be less than significant. The modifications to the proposed project would not require a change in the type of construction-related activity or an increase in duration, nor would planned utilities for the project site change. The modifications to the proposed project would be required to comply with the same mitigation measures and COAs as the proposed project. Therefore, the modifications to the proposed project would result in the same less-than-significant impacts related to utilities and service systems previously disclosed for the proposed project.
Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
Minor Modifications to Existing Site Conditions and
Surrounding Sites/Uses
Subsequent to the publication and EPC review/recommendation of the 2022 Addendum, there have been minor modifications to existing conditions at the project site and within the surrounding uses.
Within the project site, the temporary pop-up drive-through produce market that occupied the former Milk Pail site is no longer operating. The other existing conditions within the project site remain substantially similar to what was assumed in the 2022 Addendum. Within the surrounding area, the mixed-use development project along California Street, across the street from the project site (referred to as “future residential uses” in the 2022 Addendum), has been completed. The other existing conditions at surrounding sites remain substantially similar to what was assumed in the 2022 Addendum.
Evaluation of 2022 Addendum Conclusions
Per CEQA Guidelines Section 15125(a)(1), existing conditions are established at the time the Notice of Preparation (NOP) is prepared for an EIR; thus, the 2022 Addendum is not required to account for changes in existing conditions that occurred after the NOP was released and the 2022 Addendum was prepared. In addition, no updates to the cumulative analysis from the 2022 Addendum are required because the cumulative analysis in the 2022 Addendum is based on the cumulative analysis in the SAPP EIR. The SAPP EIR states that the cumulative analysis includes updated general plan land use projections from the North Bayshore, East Whisman, and San Antonio Supplemental EIRs; the SAPP, and “background conditions, including approved/un-built and under review development projects, CIPs, and regional growth (included within the SEIRs).” Thus, the potential impacts of the mixed-use development project across from the project site were accounted for in the SAPP EIR and subsequently considered and evaluated in the 2022 Addendum. Therefore, the minor modifications to existing site conditions and surrounding uses would not change the conclusions presented in the 2022 Addendum.
Updates to CEQA Thresholds of Significance for Climate
Impacts
Subsequent to the publication and EPC review/recommendation of the 2022 Addendum, the Bay Area Air Quality Management District (BAAQMD) Board of Directors adopted CEQA Thresholds for Evaluating the Significance of Climate Impacts from Land Use Projects and Plans on April 20, 2022.
The revised Guidelines provide BAAQMD-recommended procedures for evaluating potential air quality and climate impacts during the environmental review process that are consistent with CEQA requirements. The revised Guidelines supersede BAAQMD’s previous CEQA guidance titled BAAQMD CEQA Air Quality Guidelines and revised in 2017.
Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
Evaluation of 2022 Addendum Conclusions
New GHG thresholds do not constitute new information triggering the need for additional review. In short, such regulatory changes do not constitute new information; the City is not required to revisit and determine whether regulatory changes have occurred for every category whenever it tiers off of a program EIR. Therefore, the updates to the CEQA thresholds of significance for climate impacts would not change the conclusions presented in the 2022 Addendum.
Updates to City Standard Conditions of Approval
The 2022 Addendum refers to the September 20, 2021, version of the City-standard COAs.
Subsequent to the publication and EPC review/recommendation of the 2022 Addendum, there have been updates to the City standard COAs, which may have resulted in minor changes to COA numbering and text, predominantly to account for new City and/or State codes and regulations. The dates that the City standard COAs became effective are listed below. The City standard COAs will be applicable to the proposed project, and project COAs will be updated accordingly. These changes have not resulted in any removal or substantive modification to the COAs identified in the 2022 Addendum.
• Building Division & Public Works Division COAs: March 1, 2023 • Fire Department (Fire Protection) COAs: March 10, 2023 • Fire Department (Environmental Safety) COAs: September 20, 2023 • Planning Division COAs: October 25, 2021
2 Evaluation of 2022 Addendum Conclusions
The City standard COAs effective the dates listed in the section above, do not constitute new information triggering the need for additional review. As described in the previous section, the updates to the City standard COAs are primarily minor in nature. Compliance with the City standard COAs effective on the above-listed dates would not substantively modify the project and/or would reduce the impacts of the project to a similar degree as compliance to the September 20, 2021, version of the City standard COAs. Therefore, the updates to the City standard COAs would not change the conclusions presented in the 2022 Addendum.
2 It is important to note that certain City Standard COAs are now standard COAs for other departments or divisions (e.g., [Construction] work hours is now a Building Division COA). In addition, certain standard COAs may be adjusted on a case-by-case basis as a result of new State laws. For example, standard parking/operational criteria COAs may be adjusted on a project-by-project basis to reflect the limitations of AB 2097 when applicable to a project. The City is also in the process of drafting new standard COA language related to State law-directed tribal consultation requirements.
Supplemental Environmental Analysis for The Village at San Antonio – Phase III Project (SCH #2014032001) April 25, 2025
Conclusion
Based on the evaluations throughout this memorandum, minor modifications to the description of the proposed project, minor modifications to existing project/surrounding site conditions, updates to the CEQA thresholds of significance for climate impacts, and updates to the City standard COAs would not result in different impacts or changes to previously identified conclusions compared to what was disclosed in the 2022 Addendum. As such, the conclusions in the 2022 Addendum, which was prepared under CEQA Guidelines Section 15168(c) and 15164, remain valid. This memorandum also demonstrates that the modifications do not require the preparation of a supplemental or subsequent EIR because none of the conditions under CEQA Guidelines Section 15162(a) and 15163 apply. No additional environmental documentation or supplemental environmental analysis is required.

Introduction
1.1 Background
The San Antonio Precise Plan (SAPP), which the City of Mountain View (City) adopted in 2014, applies to approximately 123 acres of land near the western edge of the City. Included in the SAPP area are major roadways, such as El Camino Real, San Antonio Road, California Street, and Showers Drive. The SAPP implements goals and policies set forth in the City of Mountain View 2030 General Plan (General Plan) for the area. The SAPP provides guiding principles, policies, development criteria, and implementation strategies for transforming the existing commercial area into a mixed- use core within a broader residential neighborhood, while maximizing the area’s proximity to transit services and regional roadways. Specifically, it provides the development framework for two main subareas, the Mixed-Use Center (approximately 60 acres) and the Mixed-Use Corridor (approximately 53 acres). The SAPP area encourages a combination of uses, including office, commercial, retail, and residential.
Included in the SAPP is an office development cap to prioritize residential development and balance office development with future housing growth. The SAPP currently stipulates an areawide maximum of 600,000 square feet of net new office development, with up to 400,000 square feet permitted in the Northwest San Antonio Center Master Plan Area. Office development beyond this cap will require an amendment to the SAPP.
The Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments to the Village at San Antonio – Phase III Project (project) is located at 365 and 405 San Antonio Road and 2585 and 2595 California Street within the SAPP Mixed-Use Center Subarea and the Northwest San Antonio Master Plan Area of the SAPP. The project proposes the demolition of two single-story commercial buildings and associated surface parking, and the construction of a commercial building with public open spaces and below-grade parking garage at the southeast corner of California Street and San Antonio Road on an approximately 0.99-acre site. The project would construct a seven-story building with ground-floor retail and six levels of office uses above, along with three levels of subterranean parking that would connect to the adjacent underground parking for Phase II of the Village at San Antonio Center Project. Upon project completion, the total building area would measure approximately 182,352 gross square feet (gsf), including approximately 12,970 gsf of ground floor retail space and approximately 169,382 gsf of office space. The project site currently comprises four lots that would be merged into one lot as part of an entitlement process.
Under the SAPP, the Mixed-Use Center Subarea allows development with a FAR of up to 2.35, of which 0.75 can be office or commercial uses. In addition, the SAPP currently limits net new office development to 600,000 gsf, of which 400,000 gsf is permitted in the Northwest San Antonio Master Plan Area.
The project proposes minor amendments to the SAPP to modify the office development cap in the Northwest San Antonio Master Plan area to allow additional office area through the Transfer of Development Rights for Public Schools and update the regulations governing Transfer Development Rights for Public Schools. The existing 600,000 gsf office development limit in the SAPP as a whole would remain.

City of Mountain View
Chapter 1. Introduction
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 1-2 February 2022 ICF 104340.0.001.01
The City Council authorized the project site as a receiving site under the City’s Transfer of Development Rights (TDR) program with Los Altos School District (LASD). Per the authorization, the project applicant would seek an agreement to identify the project site as a receiving site under the City’s TDR program, allowing the 150,000 gsf transfer from the Los Altos School District to be exempt from FAR calculations.
1.2 Previously Certified EIR
The SAPP Draft Environmental Impact Report (EIR) was published in September 2014, and the Final EIR, including responses to comments on the Draft EIR, was published in November 2014. The Final EIR was certified in December 2014. As described in more detail below, this document is an addendum to the certified Final EIR, prepared under CEQA Guidelines Sections 15168(c) and 15164.
The conclusions of the Final EIR are briefly summarized at the beginning of the analysis for each of the environmental topics in this document (see Section 1.4.1, Resource Topics, below). Applicable mitigation measures presented in the SAPP EIR are incorporated into the analysis of each environmental topic, as appropriate.
Implementation of the project would require certain approvals from the City and other agencies. To allow construction of the seven-story, mixed-use building and related improvements, a lot line adjustment, precise plan amendment, master plan permit, planned community permit, development review permit, development agreement, provisional use permit, and heritage tree removal permit would be pursued.
1.3 CEQA Review of the Project
When revisions are proposed to a project after an EIR has been certified, an agency must determine whether an addendum or a supplemental or subsequent EIR is the appropriate document for analyzing the potential impacts of the revised project. Per California Environmental Quality Act (CEQA) Guidelines Section s 15162(a) and 15163, a supplemental or subsequent EIR is required if:
1. Substantial changes are proposed in the project that will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects;
2. Substantial changes occur with respect to the circumstances under which the project is undertaken that will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or
3. New information of substantial importance that was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows any of the following:
A. The project will have one or more significant effects not discussed in the previous EIR; B. Significant effects previously examined will be substantially more severe than shown in the previous EIR;

City of Mountain View
Chapter 1. Introduction
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 1-3 February 2022 ICF 104340.0.001.01
C. Mitigation measures or alternatives previously found not to be feasible would, in fact, be feasible and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or D. Mitigation measures or alternatives that are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.
If none of the above conditions apply, then an addendum is the appropriate environmental document for analyzing a revised project. Pursuant to CEQA Guidelines Section 15164(e), the addendum must provide a brief explanation regarding the decision to not prepare a supplemental EIR. The necessary explanation is set forth below.
As described in Chapter 2, Project Description, the proposed amendments to the SAPP increase the 400,000-gsf limit on net new office development within the Northwest San Antonio Master Plan, while maintaining the existing 600,000-gsf office development limit in the SAPP as a whole.
Furthermore, the project would seek an agreement to identify the project site as a receiving site under the City’s TDR program, allowing the 150,000-gsf transfer from the Los Altos School District exemption from FAR calculations. The sending site is within the San Antonio Precise Plan and does not change the maximum allowable gsf studied in the San Antonio Precise Plan EIR.
As demonstrated throughout this addendum, the proposed project would not result in new significant impacts or increases in the severity of previously identified significant impacts, and would not trigger the need for new or considerably different mitigation measures that were not identified in the certified Final EIR, thereby rendering a supplemental or subsequent EIR necessary.
Since the Final EIR was certified in December 2014, there have been changes to the background conditions in the Plan Area, and portions of the area have been constructed. However, because the changes are not substantial, the changed circumstances would not require major revisions to the Final EIR. For the foregoing reasons, no supplemental EIR is necessary. Accordingly, as described further in this document, an addendum is the appropriate mechanism for CEQA review of the proposed project.
1.4 Scope and Content of the Addendum
As permitted by CEQA Guidelines, this addendum has referenced numerous technical studies, analyses, previously certified environmental documentation, and planning documents, which have been incorporated by reference. Information from the documents has been briefly summarized in the appropriate section(s). The relationship between the incorporated part of the referenced document and the draft EIR has also been described, as appropriate. The documents and other sources used in the preparation of this addendum are provided in the appendices or listed in Chapter 5, References, of this addendum.
Consistent with CEQA Guidelines Sections 15168 (c) and 15162, this addendum compares the project-level environmental impacts of the proposed project to those identified in the SAPP EIR. The environmental impacts of the project are analyzed in this addendum to the degree of specificity appropriate, in accordance with CEQA Guidelines Section 15146.

This addendum evaluates the potential impacts of the project on the following areas:
l Air Quality
l Biological Resources
l Cultural Resources
l Geology and Soils
l Greenhouse Gas Emissions
l Hazards and Hazardous Materials
l Hydrology and Water Quality
l Land Use and Planning
l Noise
l Population and Housing
l Public Services and Recreation
l Transportation and Traffic
l Utilities and Service Systems
This addendum does not include certain CEQA resource topics because the proposed project would cause no impact to them, as described below.
l Aesthetics. The SAPP EIR concluded that with adherence to and implementation of the identified General Plan policies and actions, and the SAPP Development Standards and Guidelines, development with the Plan Area, including the project site, would result in less-than- significant aesthetic impacts. Due to the proposed project’s location within the SAPP area and other characteristics, the proposed project is deemed to have no impact, rather than a less than significant impact, on aesthetics. The project is on an infill site, within a Transit Priority Area (TPA), and is considered an employment-center project; consequently, in accordance with Public Resources Section (PRC) 21099, aesthetics and vehicular parking are not considered CEQA impacts.
l Agricultural Resources. The project site is already developed with urban uses in an urbanized environment. There are no farmlands within or near the project site that would be affected by the proposed project. There is no prime farmland or farmland of statewide importance within the Plan Area. Therefore, there would be no impact on agricultural resources. l Mineral Resources. The SAPP EIR does not identify any mineral resources within the Plan Area, and there are no known mineral resources at the project site. The proposed project would not result in the loss of availability of known mineral resources of regional or statewide importance.
Therefore, there would be no impact on mineral resources. l Wildfire. An analysis of wildfire is required only if the project site is in or near State Responsibility Areas or lands that have been classified as Very High Fire Hazard Severity Zones.
The Plan Area, inclusive of the project site, is not in one of these designated areas. Therefore, there would be no impact related to wildfire.

Project Description
2.1 Project Overview
The San Antonio Precise Plan (SAPP), which the City of Mountain View (City) adopted in 2014, applies to approximately 123 acres of land near the western edge of the city. Included in the SAPP area are major roadways, such as El Camino Real, San Antonio Road, California Street, and Showers Drive. The SAPP implements goals and policies set forth in the City of Mountain View 2030 General Plan (General Plan) for the area. Specifically, it provides the development framework for two main subareas, the Mixed-Use Center (approximately 60 acres) and the Mixed-Use Corridor (approximately 53 acres). The SAPP area encourages a combination of uses, including office, commercial, retail, and residential uses.
The Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments to the Village at San Antonio – Phase III Project (project) is located at 365 and 405 San Antonio Road and 2585 and 2595 California Street within the SAPP. The SAPP provides guiding principles, policies, development criteria, and implementation strategies for transforming the existing commercial area into a mixed-use core within a broader residential neighborhood, while maximizing the area’s proximity to transit services and regional roadways. The project proposes the demolition of two single-story commercial buildings and associated surface parking and the construction of a commercial building with public open space and below-grade parking at the intersection of California Street and San Antonio Road. On project completion, the total building area would measure approximately 182,352 gross square feet (gsf), including approximately 12,970 gsf of ground floor retail space and approximately 169,382 gsf of office space.
Included in the SAPP is an office development cap to prioritize residential development and balance office development with future housing growth. The SAPP currently stipulates an areawide maximum of 600,000 square feet of net new office development, with up to 400,000 square feet permitted in the Northwest San Antonio Center Master Plan Area. Office development beyond this cap will require an amendment to the SAPP.
2.2 Project Objectives
The project includes the following objectives to implement key SAPP project objectives on the Phase III Project site, with site-specific objectives italicized:
l Contribute to the revitalization of the SAPP plan area as a diverse and dynamic mixed-use environment, including responding to existing demand for office and commercial uses. l Create pedestrian-oriented site and building design, active frontages, and increased tree canopy. l Promote placemaking principles and create well-programmed and designed open space amenities. l Promote well-integrated development, including coordinated public access, shared parking, wayfinding signage and other amenities supporting the image and function of a cohesive area, including by integrating the Phase III Project into the existing Phase 1 and Phase II development at San Antonio Center.

l Promote transit services through higher-intensity, transit-oriented development and improved bicycle and pedestrian connections, including locating job-generating uses within close proximity to public transit.
l Encourage shared parking and access across multiple sites.
2.3 Project Location
The approximately 0.99-acre project site comprises four lots at 2585–2595 California Street and 365 and 405 San Antonio Road, in a largely mixed-use area in the western portion of the city (Figure 2-1).
Specifically, the project site is at the southeastern corner of the California Street and San Antonio Road intersection and bounded by California Street to the north, Silicon Way and commercial office buildings to the south, Promenade Lane and commercial buildings to the east, and San Antonio Road to the west. Properties surrounding the immediate area include multi-family residential uses and commercial uses, including a movie theater to the east and a gas station to the west, as shown in Figure 2-2. The project site is approximately 0.3 mile north of State Route (SR) 82 (El Camino Real), 1.4 miles south of U.S. 101, and 2.6 miles west of SR 85. The site currently consists of four legal lots, assessor’s parcel numbers 148-322-005, 148-22-006, 148-22-007, and 148-22-023.
2.4 Existing Site Conditions and Surrounding Uses
2.4.1 Project Site Land Uses
The project site consists of four lots. Existing site conditions are shown in Figure 2-3. The site currently comprises two single-story commercial buildings and surface parking lots. The building at 365 San Antonio Road is an approximately 5,008-gsf commercial office building, currently occupied by a pharmacy (PerceptiMed). The building at 2585 California Street is an approximately 4,386 gsf retail building, previously occupied by a grocery market (Milk Pail). A temporary pop-up drive-through produce market has occupied the former Milk Pail site for the past several months. In addition, there are approximately 45 surface parking spaces on the project site.
The existing project site has a floor area ratio (FAR) of 0.21, or approximately 9,394 square feet.
Approximately 12 people are currently employed at the project site. There are approximately 22 trees on the project site, including five Heritage Trees. The existing access points to the project site are from California Street and San Antonio Road. The topography of the project site is generally flat. In addition to the features described above, the site contains intermittent paving for parking and pedestrian uses.
Landscaping is found throughout the site.
2.4.2 Land Use Designation and Zoning
The City of Mountain View is organized into several geographic areas, called planning areas. The project site is within the San Antonio Planning Area, which includes a variety of commercial, office, retail, and residential uses. The General Plan also defines several change areas, which are areas within the city that could significantly change over the life of the General Plan. The General Plan identifies new land uses and intensities for change areas, primarily in industrial areas along transportation corridors and in commercial locations. The project site is within the San Antonio change area.

Chapter 2. Project Description
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 2-3 February 2022 ICF 104340.0.001.01
The General Plan designates the project site as a Mixed-Use Center, which allows for a mix of pedestrian-oriented uses, as well as integrated and complementary uses, such as residential, office, or retail uses, to draw visitors from surrounding neighborhoods and the region. The General Plan describes the permitted uses for the project site, which include offices, retail and personal services, multi-family residences, lodging facilities, entertainment venues, parks, and plazas. The project site is also within the Mixed-Use Center Subarea and the Northwest San Antonio Master Plan Area of the SAPP.
The project site is currently zoned P-40 (San Antonio Precise Plan). This zoning district is designed to provide uses or combinations of uses that may be developed appropriately as part of the San Antonio Precise Plan Area development. Specifically, it provides a development framework for two main subareas, the Mixed-Use Center (approximately 60 acres) and the Mixed-Use Corridor (approximately 53 acres). Furthermore, the zoning designation allows for a combination of uses, including office, commercial, retail, and residential. The existing commercial uses onsite are consistent with the existing General Plan land use designation and zoning for the project site.
2.4.3 Surrounding Land Uses
Surrounding land uses include other mixed uses, as well as medium-density residential uses.
Immediately east of the project site is a movie theater (ShowPlace ICON Mountain View); a gas station (Valero) is immediately west of the project site. North of California Street are existing multi- family residence uses, along with the site for future residential uses; professional offices are south of the project site.
2.5 Proposed Project
The project proposes demolition of two single-story commercial buildings, as well as associated surface parking, and construction of a commercial building with open spaces and a below-grade parking garage at the intersection of California Street and San Antonio Road on an approximately 0.99-acre site. The project would construct a seven-story building with ground-floor retail and six levels of office uses above, along with three levels of subterranean parking that would connect to the adjacent underground parking for Phase II of the Village at San Antonio Center Project (Figure 2-4). On project completion, the total building area would measure approximately 182,352 gsf, including approximately 12,970 gsf of retail space and approximately 169,382 gsf of commercial/office space. The project site currently comprises four lots that would be merged into one lot as part of an entitlement process.
The proposed building would be approximately 95 feet high.1 The project would exceed the allowable FAR (2.35) set forth in the SAPP consistent with the additional FAR permitted through the City’s Transfer of Development Rights (TDR) program. The project would not exceed the maximum allowable building height (95 feet) for the site2.
To allow construction of the seven-story, mixed-use building and related improvements, a lot line adjustment, precise plan amendment, master plan permit, planned community permit, development review permit, development agreement, provisional use permit, and heritage tree removal permit would be pursued.
1 The building would be 105 feet high at the top of the mechanical screen. 2 Per the SAPP, up to an additional 10 feet of overall height is allowed with a Provisional Use Permit for rooftop amenities.

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 2-4 February 2022 ICF 104340.0.001.01
The first floor, or ground floor, of the proposed building would measure approximately 25,270 gsf and include approximately 12,970 gsf of commercial retail space, an approximately 1,500 gsf office lobby, and space for generators/transformers, an electrical room, bathrooms, and office support (Figure 2-5). In addition, an approximately 325 gsf, single-story retail structure would be located along Promenade Lane, adjacent to proposed public open space (described in more detail below).
There would also be one loading and service area on the ground floor along Silicon Way. Floors two through six would provide office space, ranging from approximately 15,247 gsf to 31,000 gsf. The subterranean parking garage would provide parking for approximately 283 cars, with each of the three levels measuring approximately 36,450 square feet Project implementation would provide private and public open spaces throughout the site. The streetscape would consist of at-grade and raised planters with built-in seating. A series of at-grade planting buffers would be situated between the street and the sidewalk to mitigate noise and block views. In addition, benches, bicycle racks, and lighting would be provided, per City and California Green Building Standards Code (CALGreen) requirements. Approximately 20,633 square feet of public open space would be provided on the ground floor of the building, including landscape, seating areas and outdoor dining. A public plaza would be located at the corner of California Street and San Antonio Road, as well as an outdoor seating area along Promenade Lane. In addition, approximately 17,715 square feet of private open space would be provided onsite, including balconies and landscaping on the upper floors.
A total of approximately 1,500 office employees would work at the project site upon completion and occupancy of the new building.
2.5.1 San Antonio Precise Plan Amendment and Transfer of Development Rights
The project site is within the Mixed-Use Center Subarea and the Northwest San Antonio Master Plan Area of the SAPP.
Under the SAPP, the Mixed-Use Center Subarea allows development with a FAR of up to 2.35, of which 0.75 can be office or commercial uses. In addition, the SAPP currently limits net new office development to 600,000 gsf, of which 400,000 gsf is permitted in the Northwest San Antonio Master Plan Area.
To implement the project, the project applicant proposes an amendment to the SAPP and minor amendments to the SAPP to modify the office development cap in the Northwest San Antonio Master Plan area to allow additional office development through the Transfer of Development Rights for Public Schools and update the regulations governing Transfer Development Rights for Public Schools. The existing 600,000 gsf office development limit in the SAPP as a whole would remain.
The City Council authorized the project site as a receiving site under the TDR program with Los Altos School District (LASD). Per the authorization, the project applicant would seek an agreement to identify the project site as a receiving site under the City’s TDR program, allowing the 150,000 gsf transfer from the Los Altos School District to be exempt from FAR calculations. Additional required approvals from the City and other agencies are identified in Section 2.7, Required Permits and Approvals.

2.5.2 Site Access, Circulation, and Parking
As shown in Figure 2-5, vehicular access to the project site would be provided from San Antonio Road, similar to existing conditions. The project would include one entrance and one exit for the subterranean parking garage through the adjacent underground parking garage that was completed as part of the Phase II Village at San Antonio Center Project. The access to the joint underground garage is off San Antonio Road and under Silicon Way. The project would also include approximately 283 vehicle parking spaces in the three levels of below-grade parking, including spaces that would be reserved for Americans with Disabilities Act (ADA)-compliant vehicles, in accordance with applicable requirements. In addition, the project would meet the City of Mountain View’s Building Code electric vehicle parking requirements by providing electric-vehicle charging stations onsite.
The project would enhance the site’s pedestrian and bicyclist connectivity. Pedestrian pathways would be provided around the exterior of the proposed building to promote circulation between the various commercial uses. Existing bicycle lanes along California Street and San Antonio Road would be maintained. The project would also provide Type I and Type II bicycle parking and bicycle storage onsite. In total, approximately 48 bicycle parking spaces would be provided onsite, including 28 permanent bicycle lockers and 20 bicycle racks.
Emergency vehicles would be able to access the project site from one location on California Street and one location on San Antonio Road. In addition, the internal project streets of Silicon Way and Promenade Lane would provide full emergency access around the project site. Silicon Way is approximately 22 feet wide; Promenade Lane is approximately 26 feet wide. Furthermore, additional fire hydrants would be installed at the project site.
The project would include one new loading berth along Silicon Way.
2.5.3 Building Design and Sustainability Features
The project would be designed to integrate the surrounding aesthetic and enhance the pedestrian experience at the major intersection of California Street and San Antonio Road . Balconies, decks, punched openings, colonnades, and other details, such as mullion frames, would be incorporated into the building design to create visual interest. The building exterior would comprise various materials, including limestone, glass, wood, architectural concrete, and metals (Figure 2-6).
Façade articulation between glass and solid materials and landscaping at each wraparound deck would be incorporated to reduce solar exposure and the heat island effect. The project’s design would help reduce the visual size and scale of the building.
Accent lighting would be provided to highlight the proposed building’s architectural features, such as corners and lobbies.
The project applicant intends to pursue Leadership in Energy and Environmental Design (LEED) Gold certification for the project. The multitude of sustainable strategies that could be incorporated include low-flow plumbing fixtures, Ener gy Star appliances, light -emitting diode (LED) technology, drought-tolerant landscaping, low -flow irrigation systems, bio -filtration planters for stormwater management, a highly efficient building envelope to mitigate solar heat gain, light-colored surfaces, and below-grade parking to reduce the heat island effect. In addition, 14 percent of the vehicle parking spaces would be designated for electric, clean air, or vanpool vehicles. Outlets would be provided for recharging electric vehicles .

2.5.4 Landscaping and Heritage Trees
The project would include a landscape plan to compensate for the removal of trees and vegetation and enhance the development. Figure 2-7 shows the proposed landscaping elements for the project.
There are 22 trees on the project site. Of these, five meet the City’s criteria for Heritage Trees. It is anticipated that 13 trees, including the five Heritage Trees, would need to be removed for project construction. Upon project buildout, 28 trees would be provided on the site, including nine existing trees and 19 new trees. All trees and other landscape would be planted be in compliance with the provisions of City and California Water Conservation in Landscaping Regulations. All planted areas would be watered with an approved irrigation system to make efficient use of water through conservation techniques, in compliance with applicable City and State regulations.
With implementation of the project, the streetscap e would consist of at -grade and raised planters with built-in seating. In addition, streetscape improvements would include a combination of new trees and transplanted trees. Landscape would surround the building frontages up to the street.
2.5.5 Utilities
Given the already developed nature of the site, the project would be able to connect to existing City utilities, as described below. The project would provide new utility service connections for domestic water, recycled water, storm drain s, sanitary sewer lines, gas lines, communications infrastructure, and electrical service. Off-site utility improvements are not anticipated. All new utilities would maintain the standard City horizontal clearance from trees ( i.e., 5 feet for water utilities and 10 feet for sewer s).
Water
The project proposes to construct new wet utility service connections. Two 2-inch domestic water connections are proposed to connect to an existing 10-inch main in California Street. One of these connections would be connected in the future to recycled water mains once extended into the project area. In addition, an 8-inch fire service would be connected to the 10-inch main in California Street. Further, an existing 1.5-inch domestic water meter from San Antonio Road may be converted to an irrigation service or new 1.5-inch irrigation service as part of the proposed project. The irrigation service line would be converted to recycled water when it becomes available to the project site and surrounding area.
Wastewater
The proposed project would include a 6-inch sanitary sewer connection to an existing 8-inch main in California Street. All other existing wastewater utility infrastructure would remain.
Stormwater
The proposed project would install two 8-inch storm drains that would also connect to an existing 30-inch storm main in California Street. High capacity bio-filtration best management practices would be used on the project site to treat stormwater. In addition, planter boxes and a LID-based treatment system would be used to treat stormwater runoff from the roof of the proposed building.
Further, proprietary biofiltration units and non-LID treatment systems would be used to treat ground-level stormwater runoff.

Dry Utilities
The project proposes to construct new dry utility service connections. A 3-inch gas connection would be provided from San Antonio Road. All electrical and telecommunication utilities would be connected to existing electrical and telecommunication utilities in California Street.
Solid Waste
The City has contracted with Recology to provide residential and commercial waste and recycling services to all residents and businesses within the city. The project site would be served by Recology under this contract. In addition, there is a trash management plan already in place for all of Phase II, which would be amended to incorporate the project.
2.5.6 Transportation Demand Management
The project proposes the following Transportation Demand Management (TDM) measures and strategies, which are anticipated to reduce peak-hour traffic by approximately 30 percent. These measures include, but are not limited to:
l Providing secure, transit-oriented building entrances l Enhancing transit stops, pedestrian crossings, and bicycle network through incorporation of shuttle stops and passenger loading zones, and supporting new bike signage, sharrows, and lanes
l Constructing secure bicycle parking
l Providing an onsite bicycle maintenance and repair station l Implementing a Bicycle Share program;
l Installing onsite showers and locker rooms
l Creating onsite car share spaces
l Providing TDM information space
l Identifying or hiring a TDM coordinator

required during construction of the proposed building. All off-road diesel-powered equipment used during construction would be equipped with EPA-approved Tier 4 Final engines. Evidence regarding the use of Tier 4 Final engines or cleaner during project construction would be provided to the City by the project applicant or construction contractor.
Demolition would generate approximately 1,547 cubic yards of material, including trees, concrete, and asphalt. Construction of the below-grade parking garage and the foundation would require excavation work. The project would excavate to a maximum depth of approximately 55 feet below the ground surface, which would result in the export of approximately 55,350 cubic yards of soil. In total, demolition and excavation for the project would result in approximately 56,897 cubic yards of off-haul material.
Demolition debris, removed trees, concrete and asphalt, and materials from garage excavation and miscellaneous grading would be transported to either the Newby Island Landfill or Dumbarton Quarry. The haul route to the Newby Island Landfill or Dumbarton Quarry would involve heading north San Antonio Road, east on Old Middlefield Way, and then traveling southbound on U.S. 101.
The haul route for trucks returning to the project site would be in the opposite direction.
2.6.1 Construction Hours
Project construction would comply with Section 8.70.1 of the City of Mountain View Municipal Code, which includes regulations related to noise generated by construction. It stipulates that no construction activity will commence prior to 7:00 a.m. or continue later than 6:00 p.m. Monday through Friday. In addition, no work will be permitted on Saturdays, Sundays, or holidays, unless the Chief Building Official grants prior written approval.
2.7 Required Permits and Approvals
Implementation of the project would require approvals from the City and other agencies. The approvals and entitlements anticipated for implementation of the project include:
l Precise Plan Amendment
l Master Plan Permit
l Development Agreement
l Development Review Permit
l Planned Community Permit
l Provisional Use Permit
l Lot Line Adjustment
l Heritage Tree Removal Permit

Environmental Impacts Checklist
Organization of This Section
For each environmental topic, this analysis section provides a brief summary of impacts associated with implementation of the San Antonio Precise Plan (SAPP) as discussed in the Final SAPP Environmental Impact Report (EIR) certified on November 7, 2014. In addition, this section provides a discussion of the potential impacts under the proposed project. Because this addendum only addresses changes to a portion of the SAPP Plan Area, this document focuses on a comparison between the proposed project and the conclusions reached in the Final SAPP EIR. In instances where the Final SAPP EIR does not specifically describe the impacts from the proposed project, this document compares the impacts of the proposed project with the overall conclusions made regarding implementation of the SAPP. The project applicant is not seeking any other changes to the SAPP beyond the proposed project; therefore, no other components of the SAPP are explicitly discussed in this analysis.
Summary of Environmental Impacts
Table 3.0-1 summarizes the main conclusions of each environmental topic under both the SAPP EIR and the proposed project. As indicated in Table 3.0-1, all conclusions in the SAPP EIR would remain the same for the proposed project. Although some impacts would be slightly less than or slightly greater than those of the SAPP EIR, these changes would be minor and would not affect the significance conclusions in the Final EIR.
Topics Found to Have No Impact
Based on knowledge of the project site and surrounding areas, it was determined in the certified Final SAPP EIR that there would be no plan-related impacts on aesthetics, agriculture and forestry resources, mineral resources, or wildfire because these resources are not present in the Plan Area vicinity. The same conclusion of “no impact” applies to the proposed project.
Aesthetics
The SAPP EIR concluded that with adherence and implementation of the identified General Plan policies and actions and the SAPP Development Standards and Guidelines, the SAPP would result in less- than significant aesthetic impacts.
Due to the proposed project’s location within the SAPP area and other characteristics, the proposed project is deemed to have no impact, rather than a less than significant impact, on aesthetics. Public Resources Code (PRC) Section 21099, Modernization of Transportation Analysis for Transit-Oriented Projects, provides that impacts to aesthetics and parking will not be considered in determining if a project has the potential to result in significant environmental effects, provided the project meets the following criteria under PRC Section 21099:
Attachment 1
City of Mountain View
Chapter 3. Environmental Impacts Checklist
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3-2 February 2022 ICF 104340.0.001.01
l The project is on an infill site.
l The project is in a Transit Priority Area (TPA).
l The project is a residential, mixed-use residential, or employment-center project.
The proposed project meets the above criteria as a qualifying employment-center project for purposes of PRC Section 21099 and, therefore, aesthetics and vehicular parking are not further analyzed. The project site is a qualifying infill site that is currently developed with existing commercial and retail uses. The entire perimeter of the project site adjoins urban uses or public rights-of-way. The Metropolitan Transportation Commission (MTC) has identified locations of TPAs within the Bay Area (MTC 2017). MTC mapping indicates that the entire project site is within a TPA, due to its proximity to the Caltrain San Antonio Station. The project site is zoned San Antonio Precise Plan (P-40) under the City’s Zoning Code. The proposed project would demolish all existing uses on the project site and construct an approximately 182,352 gross square foot (gsf) building with approximately 12,970 gsf of ground floor retail space and approximately 169,382 gsf of office space. The project would exceed the allowable FAR (2.35). Therefore, the proposed project qualifies as an employment center project.
Because the project meets the three criteria above, this addendum does not consider aesthetics or vehicular parking in determining the significance of impacts under CEQA.
Agriculture and Forestry Resources
The SAPP EIR concluded that implementation of the Plan would have no impact on agricultural or forestry resources, as the Plan Area is an urban developed area and not zoned for or used for agriculture or forestry purposes. In addition, the Plan Area is not designated by the Department of Conservation as farmland of any type, and is not subject to a Williamson Act contract. Further, no properties adjacent to the Plan Area are used or zoned for agriculture or forestry purposes.
As the proposed project is located within the Plan Area, the conclusions as they relate to impacts to agricultural and forestry resources have not changed, and the proposed project would result in no impacts to agriculture and forestry resources.
Mineral Resources
The SAPP EIR concluded that implementation of the Plan would not result in any impacts to mineral resources as the Plan Area is located in a developed urban area and mineral exploration and extraction are not performed in the vicinity. In addition, there are no minerals or aggregate resources of statewide importance located in the Plan Area as defined by the State of California mapping system. Since the proposed project is located within the Plan Area, the conclusions as they relate to impacts to mineral resources have not changed, and the proposed project would result in no impacts to mineral resources.
Wildfire
The SAPP EIR concluded that implementation of the Plan would result in less than significant impacts related to wildfire, as there are no Fire Hazard Severity Zones for State Responsibility areas or Very High Fire Hazard Severity Zones for local responsibility areas within or adjacent to the Plan Area according to the California Department of Forestry and Fire Protection (CAL FIRE)’s Fire Attachment 1

Air Quality Mitigation Measure AIR-1 All new development projects, associated with implementation of the SA Precise Plan, which include buildings within 1,000 feet of a residential dwelling unit shall conduct a construction health risk assessment to assess emissions from all construction equipment during each phase of construction prior to issuance of building permits. Equipment usage shall be modified as necessary to ensure that equipment use would not result in a carcinogenic health risk of more than 10 in 1 million, an increased non-cancer risk of greater than 1.0 on the hazard index (chronic or acute), or an annual average ambient PM2.5 increase greater than 0.3 μg/m3.
Noise Mitigation Measure
NOISE-1
The following language shall be included as a Condition of Approval for new projects associated with implementation of the SA Precise Plan:
l In the event that pile driving would be required for any proposed project within the SA Precise Plan area, all residents within 300 feet of the project site shall be notified of the schedule for its use a minimum of one week prior to its commencement. The contractor shall implement “quiet” pile driving technology (such as pre-drilling of piles, the use of more than one pile driver to shorten the total pile driving duration, or the use of portable acoustical barriers) where feasible, in consideration of geotechnical and structural requirements and conditions. l To the extent feasible, the project contractor shall phase high-vibration generating construction activities, such as pile-driving/ground-impacting operations, so they do not occur in the same period with demolition and excavation activities in locations where the combined vibrations would potentially impact sensitive areas.
l The project contractor shall select demolition methods not involving impact, where possible (for example, milling generates lower vibration levels than excavation using clam shell or chisel drops).
l The project contractor shall avoid using vibratory rollers and packers near sensitive areas whenever possible.

3.1 Air Quality
The U.S. Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS) for six criteria air pollutants that are known to be harmful to human health and the environment, carbon monoxide (CO); lead; nitrogen dioxide (NO2); ozone; particulate matter, which is categorized as respirable particulate matter with an aerodynamic diameter less than or equal to 10 microns (PM10) and fine particulate matter with an aerodynamic diameter less than or equal to 2.5 microns (PM2.5); and sulfur dioxide (SO2). The California Air Resources Board (CARB) established the California Ambient Air Quality Standards (CAAQS) for these six pollutants as well as sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particles. The NAAQS and CAAQS represent scientifically substantiated numerical concentrations of criteria air pollutants. The standards have been established to protect the public from adverse health impacts caused by exposure to air pollution. A brief description of the criteria air pollutants, as well as their effects on health, is provided in Table 3.1-1.
The project site is in Santa Clara County. It is also within the San Francisco Bay Area Air Basin (SFBAAB). This large, shallow air basin is ringed by hills that taper into a number of sheltered valleys around the perimeter. The SFBAAB has two primary atmospheric outlets. One is the strait known as the Golden Gate, a direct outlet to the Pacific Ocean. The other primary outlet extends to the northeast, along the West Delta region of the Sacramento and San Joaquin Rivers.
The SFBAAB is currently designated as a non-attainment area with respect to the NAAQS and CAAQS for ozone, the CAAQS for PM10, and the CAAQS for PM2.5. The SFBAAB is designated as attainment unclassifiable with respect to the NAAQS and CAAQS for all other criteria air pollutants.1

Table 3.1-1. Criteria Air Pollutants
Pollutant Sources Effects
Ozone Ozone is a secondary air pollutant. It is produced in the atmosphere through a complex series of
photochemical reactions involving reactive
organic gases (ROGs), sometimes referred to as
volatile organic compounds by some regulating
agencies, and nitrogen oxides (NO
X). The main
sources of ROGs and NOX, which are referred to
as ozone precursors, are by-products of
combustion processes, including exhaust from
motor vehicle engines, and evaporation involving
solvents, paints, and fuels.
Ozone causes eye irritation, airway
constriction, and shortness of breath
and can aggravate existing respiratory
diseases, such as asthma, bronchitis,
and emphysema.
Carbon
monoxide
Carbon monoxide (CO) is usually formed as the
result of the incomplete combustion of fuel. The
single largest source of CO is motor vehicle
engines. The highest emissions occur during low
travel speeds, stop-and-go driving, cold starts,
and hard acceleration.
Exposure to high concentrations of CO
reduces the oxygen-carrying capacity of
the blood. It can cause headaches,
nausea, dizziness, and fatigue; impair
central nervous system functions; and
induce angina (chest pain) in persons
with serious heart disease. Very high
levels of CO can be fatal.
Particulate
matter
Some sources of particulate matter, such as wood
burning in fireplaces, demolition, and
construction activities, are more local in nature,
while others, such as vehicular traffic, have a
more regional effect.
Scientific studies have suggested links
between fine particulate matter and
numerous health problems, including
asthma, bronchitis, and acute and
chronic respiratory symptoms, such as
shortness of breath and painful
breathing. Recent studies have shown
an association between morbidity and
mortality and the daily concentrations
of particulate matter in the air.
Nitrogen
dioxide
NO2 is a reddish-brown gas. It is a by-product of
combustion processes. Automobiles and
industrial operations are the main sources of
NO2.
Aside from its contribution to ozone
formation, NO2 can increase the risk of
acute and chronic respiratory disease
and reduce visibility.
Sulfur
dioxide
Sulfur dioxide (SO2) is a by-product of
combustion involving sulfur or sulfur-containing
fuels, such as coal and diesel.
SO2 is also a precursor to the formation
of particulate matter, atmospheric
sulfate, and atmospheric sulfuric acid
formation that could precipitate
downwind as acid rain.
Lead Leaded gasoline, lead-based paint, smelters
(metal refineries), and manufacturers of lead
storage batteries have been the primary sources
of the lead that gets released into the
atmosphere. Lead levels in the air decreased
substantially after leaded gasoline was
eliminated in the United States.
Lead has a range of adverse neurotoxic
health effects.

The Bay Area Air Quality Management District (BAAQMD) is the local agency responsible for air quality planning and the development of air quality plans in the SFBAAB. BAAQMD develops and implements its Clean Air Plan for attaining the NAAQS and CAAQS while accounting for future growth in the SFBAAB. The Clean Air Plan was last updated and approved by BAAQMD’s Board of Directors and CARB in 2017.2 BAAQMD also develops regulations and emission reduction programs to control emissions of criteria air pollutants and precursors, toxic air contaminants (TACs), and odors within its jurisdiction.
EPA and CARB also regulate air toxics. EPA refers to this category of pollutants as hazardous air pollutants (HAPs); CARB refers to them as TACs. This report uses TACs. TACs are a defined set of airborne pollutants that may cause or contribute to an increase in mortality or serious illness or pose a hazard to human health. TACs are usually present in minute quantities in the ambient air; however, their high toxicity or health risk may pose a threat to public health, even at low concentrations. A wide range of sources, from industrial plants to motor vehicles, emit TACs. The health effects associated with TACs are quite diverse and generally assessed locally rather than regionally. TACs can cause long-term health effects, such as cancer, birth defects, neurological damage, asthma, bronchitis, or genetic damage, or short-term acute affects, such as watery eyes, respiratory irritation (a cough), a running nose, throat pain, or headaches.
BAAQMD published its California Environmental Quality Act Air Quality Guidelines in 2017 to assist lead agencies in the evaluation of the air quality impacts of projects as well as plans proposed within the SFBAAB.3 The guidelines recommend procedures for evaluating potential impacts on air quality during the environmental review process, consistent with California Environmental Quality Act (CEQA) requirements. The guidelines also include background information about air quality in the SFBAAB; recommended methods for analyzing a project’s criteria air pollutants and precursors, TACs, and odorous emissions; thresholds of significance for determining whether project-generated emissions would result in impacts on air quality and adverse effects on human health; and mitigation measures to reduce impacts on air quality. This guidance is employed below to assess the project’s potential impact on air quality.
a. Would the project conflict with or obstruct implementation of the applicable air quality plan? The SAPP EIR evaluated whether implementation of the SAPP would be consistent with BAAQMD’s 2010 Clean Air Plan. As explained in the SAPP EIR, the 2010 Clean Air Plan was BAAQMD’s comprehensive plan to improve air quality and protect public health in the San Francisco Bay Area.
The design and development standards in the SAPP are consistent with the 2010 Clean Air Plan because they promote mixed-use, compact development to reduce motor vehicle travel and associated emissions; encourage the use of transit (e.g., by locating diverse high-density development near the San Antonio Caltrain station); improve pedestrian and bicycle connections, crossings, and facilities; promote improved connectivity for all travel modes to adjacent neighborhoods and downtown; and enable visitors who arrive by car to park once and walk to multiple destinations. For these reasons, the SAPP EIRSAPP EIR concluded that implementation of

the SAPP would not conflict with the transportation control measures or the energy and climate control measures outlined in the 2010 Clean Air Plan. Therefore, the SAPP EIR concluded that this impact would be less than significant.
The types of land uses and associated emission sources developed by the proposed project would be the same as those analyzed in the SAPP EIR.
Subsequent to adoption of the SAPP EIR by the City of Mountain View (City) in 2014, BAAQMD adopted its 2017 Clean Air Plan, which replaced the 2010 Clean Air Plan. The 2017 Clean Air Plan generally contains the same control measures as the 2010 Clean Air Plan; it also contains some additional rules adopted since 2010. Most of the new rules apply to industrial sources, which would not be part of the land uses developed under the SAPP or by the proposed project. One new transportation control measure adopted by BAAQMD, Rule 14-1, implements the Bay Area Commuter Benefits Program. It requires employers with 50 or more Bay Area employees to provide commuter benefits to encourage ridesharing, using transit, cycling, and walking for work-related trips. As an adopted rule, this new measure would apply to all future employment-related land uses developed under the SAPP, including the new land uses developed as part of the proposed project.
Moreover, the proposed project would be in compliance with other applicable measures in the 2017 Clean Air Plan by increasing land use density in the Mixed-Use Center Subarea of the SAPP, locating job-generating uses close to the San Antonio Caltrain station, improving bicycle and pedestrian connections around the site, providing Type I and Type II bicycle parking and bicycle storage on-site as well as pedestrian amenities consistent with requirements in the California Green Building Standards Code, and including electric-vehicle charging infrastructure. Therefore, the proposed project would not conflict or obstruct with implementation of an air quality plan. This impact would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the project’s consistency with BAAQMD’s air quality planning efforts that were analyzed in the SAPP EIR. b. Would the project result in a cumulatively considerable net increase in any criteria pollutant for which the project region is in non-attainment status under an applicable federal or state ambient air quality standard?
As discussed above, EPA and CARB established the NAAQS and CAAQS, respectively, to protect the public from adverse health impacts associated with exposure to high concentrations of criteria air pollutants. Also discussed above, the SFBAAB is currently designated as a non-attainment area with respect to the NAAQS and CAAQS for ozone, the CAAQS for PM10, and the CAAQS for PM2.5.4 Separate discussions about emissions of criteria air pollutants and precursors emitted during project construction and operation are provided below.
Construction-Generated Emissions of Criteria Air Pollutants and Precursors The SAPP EIR states that emissions of criteria air pollutants and precursors generated by construction activities under the SAPP would not result in an exceedance of any NAAQS or CAAQS because all construction projects would be required to implement City Standard Condition of Approval (COA) PL-192, which requires implementation of BAAQMD’s Basic Construction Mitigation Measures to reduce fugitive dust emissions. The types of emissions-generating activities that would

occur during construction of the proposed project would be similar to those analyzed in the SAPP EIR. Such emissions-generating activities may include trips made by commuting workers as well as the use of heavy-duty construction equipment, the use of haul trucks to transport materials and equipment to and from the site, and the application of architectural coatings. City Standard COA PL- 192 would also require the proposed project to implement BAAQMD’s basic construction mitigation measures to reduce fugitive dust emissions.
In addition to fugitive dust, construction activities would result in emissions of criteria air pollutants from the use of off- and on-road vehicles and equipment. The air district provides screening-level sizes for land use projects in Table 3-1 of its CEQA Guidelines.5 It can be assumed that projects that meet the screening criteria in the air district’s CEQA Guidelines would not result in the generation of construction-related criteria air pollutants and/or precursors that would exceed thresholds of significance. Other screening criteria are discussed in Section 3.5.1 of the air district’s CEQA Guidelines. The criteria specify that projects that would not require demolition activity, projects that would not require the simultaneous occurrence of more than two construction phases, and projects that would not involve extensive site preparation or extensive material transport operations (e.g., involving more than 10,000 cubic yards of soil import/export) would result in a less-than- significant impact. If a project meets the criteria, then a detailed analysis of construction-related criteria air pollutants is not required.
The proposed project would involve some demolition activity and include material transport operations involving more than 10,000 cubic yards of soil; therefore, the air district screening criteria would not be met directly. However, based on the City’s experience from conducting quantitative criteria air pollutant analyses for larger projects that required more excavation and still resulted in emissions that were below the air district’s significance thresholds, it can be assumed that the proposed project would not exceed the thresholds. This conclusion is further substantiated by the fact that the proposed project would have only 66 percent of the air district’s construction criteria pollutant screening criterion value for the amount of office space (approximately 182,352 square feet compared to 277,000 square feet). Therefore, quantification of project-generated criteria air pollutant emissions would not be required. The proposed project would not exceed any of the significance thresholds for criteria air pollutants and would result in less-than-significant impacts.
The proposed project would not exceed the thresholds established for construction-related fugitive dust or criteria air pollutants. Therefore, construction of the proposed project would not result in a cumulatively considerable contribution to criteria pollutants for which the SFBAAB has been designated as a non-attainment area with respect to the NAAQS or CAAQS. This impact would be less than significant.
Operational Emissions of Criteria Air Pollutants and Precursors The SAPP EIR determined that emissions of criteria air pollutants and precursors associated with the operation of land uses under the SAPP would not result in an exceedance of any NAAQS or CAAQS, based on the two significance criteria recommended by BAAQMD for evaluating plan-level impacts. First, as described in the response to question “a,” above, the SAPP would be consistent with the applicable emissions control measures of BAAQMD’s 2010 Clean Air Plan. Second, the

increase in the number of vehicle trips associated with implementation of the SAPP would not exceed the increase in the service population (i.e., residential population plus the employee population) supported by this development.
As noted above, the air district provides screening-level sizes for land use projects in Table 3-1 of its CEQA Guidelines. As stated in the guidelines, “if a project meets the screening criteria in Table 3-1, a project would not result in the generation of operational-related criteria air pollutants and/or precursors that exceed the thresholds of significance.”6 If a project meets the criteria, then a detailed analysis of operational criteria air pollutants is not required.
The screening-level size for operational criteria air pollutants pertaining to a general office building is 346,000 square feet. Because the proposed project would approximately 182,352 square feet, it would meet the screening criteria, and a detailed analysis would not be required. Therefore, quantification of project-generated criteria air pollutant emissions would not be required.
Consequently, the proposed project would not exceed any of the significance thresholds for criteria air pollutants, resulting in a less-than-significant impact.
Summary
Because construction and operation of the proposed project would not result in a cumulatively considerable contribution to criteria pollutants for which the SFBAAB is designated as a non- attainment area with respect to the NAAQS or CAQQS, this impact would be less than significant.
Therefore, the findings of the SAPP EIR remain valid regarding construction-related or operational emissions of criteria air pollutants and precursors, and no further analysis is required on this topic in a supplemental or subsequent EIR. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts related to cumulatively considerable contribution to criteria pollutants that were analyzed in the SAPP EIR. c. Would the project expose sensitive receptors to substantial pollutant concentrations? Sensitive receptors include those land uses where exposure to pollutants could result in health- related risks for sensitive individuals, including children and the elderly. Residential dwellings, schools, hospitals, day-care facilities, and similar facilities are of primary concern because of the presence of individuals who are particularly sensitive to pollutants and/or the potential for increased and prolonged exposure to pollutants.
Separate discussions are provided below regarding the proposed project’s potential to expose sensitive receptors to substantial concentrations of TACs during project construction, TACs during long-term operation of stationary sources, or CO resulting from project-induced traffic congestion.
Construction-Generated Emissions of Toxic Air Contaminants The SAPP EIR discussed TACs emitted during construction activity. The construction of new development under the SAPP would result in temporary, intermittent emissions of diesel particulate matter (DPM) from the exhaust of the heavy-duty off-road diesel equipment used for grading and excavation, utility installations, paving, building construction, the application of architectural coatings, and building demolition. CARB identified DPM as a TAC in 1998. Furthermore, DPM is the primary TAC of concern associated with construction activity. Because of the lack of specific

construction information available at the time when the SAPP EIR was prepared, the program-level analysis in the SAPP EIR determined that the construction of new projects under the SAPP could result in the exposure of sensitive receptors to substantial concentrations of DPM and associated health risks, which would represent a significant impact. Mitigation Measure AIR-1 in the SAPP EIR requires all new development projects to conduct a construction health risk assessment and modify equipment usage as necessary to ensure that construction activity does not result in a carcinogenic health risk of more than 10 in 1 million, an increased non-cancer risk of more than 1.0 on the hazard index (chronic or acute), or an annual average ambient PM2.5 increase greater than 0.3 microgram per cubic meter (μg/m3). Therefore, the SAPP EIR determined that the impact would be less than significant with mitigation.
Construction of the proposed project would involve the same types of DPM-emitting activities that were analyzed in the SAPP EIR. Therefore, implementation of Mitigation Measure AIR-1 from the SAPP EIR would be required to reduce this impact to a level less than the health risk exposure criteria recommended by BAAQMD (i.e., an incremental increase in cancer risk greater than 10 in 1 million). The proposed project’s TAC impacts are evaluated in the discussion that follows.
The primary TAC of concern associated with the proposed project is DPM, which is a carcinogen emitted by diesel internal-combustion engines. Construction activities would generate DPM (PM2.5 exhaust)7 that could expose adjacent receptors to significant health risks. As noted in Chapter 2, Project Description, all off-road diesel equipment used during construction would be equipped with EPA-approved Tier 4 Final engines, which would result in reduced DPM emissions relative to the average engine tier for construction equipment in California. Table 3.1-2 presents the maximum construction-related health risks for the maximum exposed receptor within 1,000 feet of construction activities.

Notes:

As shown in Table 3.1-2, neither the cancer risk, non-cancer hazard index, or annual PM2.5 concentration at the maximum exposed receptor would exceed BAAQMD’s threshold of 10 per 1 million, 1, or 0.3 µg/m3, respectively. Therefore, this impact would be less than significant.
Cumulative Emissions of Toxic Air Contaminants
According to BAAQMD’s guidelines, combined risk and concentration levels should be determined at all nearby DPM and PM2.5 sources within 1,000 feet of a project site. In addition, the combined risk and concentration levels should be compared to BAAQMD’s cumulative thresholds.
7 Per BAAQMD guidance, PM2.5 exhaust is used as a surrogate for DPM.

The proposed project would involve construction activities that would generate DPM and PM2.5.
Existing DPM and PM2.5 sources within 1,000 feet of the project site could, along with the proposed project, contribute to a cumulative health risk for existing and future sensitive receptors adjacent to or within the project site. BAAQMD data files and distance multipliers provided by BAAQMD were used to estimate background impacts and concentrations for existing stationary, roadway, and rail sources. The combined risks from the proposed project and ambient sources are summarized in Table 3.1-3. The methods used to estimate project emissions are described in Appendix A.

Notes:

As shown in Table 3.1-3, the cumulative cancer risk and hazard index would not exceed BAAQMD’s cumulative thresholds. However, the cumulative annual PM2.5 concentration would exceed BAAQMD’s threshold. This represents a potentially significant cumulative impact. However, the proposed project’s contribution to that cumulative impact would not be considerable because the project-only contribution would be relatively minor and much smaller than that of the ambient sources. As shown in the table above, the vast majority of the PM2.5 concentration (i.e., approximately 97 percent) is from existing ambient roadway sources; less than 3 percent would be from the proposed project. In light of this, the proposed project’s contribution would not be considered considerable. Although the total cumulative PM2.5 concentration would exceed BAAQMD’s threshold, the threshold would be exceeded even in the absence of the proposed project.
Therefore, the proposed project’s contribution would not substantially change the PM2.5 concentration at the maximum exposed receptor. This impact would be less than significant.
Stationary-Source Emissions of Toxic Air Contaminants
The SAPP EIR explained that any new stationary sources of TACs (e.g., boilers, backup diesel generators) developed under the SAPP would be subject to BAAQMD permitting requirements, thereby ensuring that they would not emit levels of TACs that would expose sensitive receptors, such as schools and residences, to excessive health risks. This would also be true for the proposed project.

Mobile-Source Emissions of Carbon Monoxide
The SAPP EIR did not evaluate the potential for traffic associated with operation of new land uses under the SAPP to result in, or contribute to, localized conc entrations of CO that would exceed the applicable NAAQS or CAAQS. However, because heavy traffic congestion can contribute to high levels of CO, and individuals exposed to such hot spots may have a greater likelihood of developing adverse health effects , traffic analysis is provided herein for the proposed project.
BAAQMD has adopted the following screening criteria , which provide a conservative indication of whether project -generated traffic would cause a potential CO hot spot :
1. The project would be consi stent with an applicable congestion management program (CMP) established by the county congestion management agency for designated roads or highways, a regional transportation plan, and local congestion management agency plans;
2. Project traffic would not i ncrease traffic volumes at affected intersections beyond 44,000 vehicles per hour; and
3. Project traffic would not increase traffic volumes at affected intersections beyond 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially li mited (e.g., a tunnel, parking garage, bridge underpass, natural or urban street canyon, below -grade roadway).
As shown in Table 16 of the Multimodal Transportation Analysis (MTA) for the proposed project, there would be no conflicts at intersections that are considered CMP intersections . 8 The
proposed project would not result in a change in level of service or substantially increase average critical delay at any of the CMP intersections.
Figure 12 of the MTA presents the AM and PM peak -hour intersection v ehicle volume s for existing plus -project conditions. In that figure, it is apparent that the combined vehicle volumes at each intersection would be well below 24,000 vehicles per hour. As such, the proposed project would not exceed the BAAQMD screening cri teria for peak -hour intersection vehicle volumes.
Because the proposed project would not violate the screening criteria , traffic generated by the proposed project would not result in, or contribute to, localized CO concentrations that would exceed the applicable NAAQS or CAAQs.
Summary
Any new stationary sources of TACs (e.g., boilers, backup diesel generators) that would operate as part of the proposed project would be subject to BAAQMD permitting requirements , thereby ensuring that they would not expose sensitive receptors to health risk s that would exceed BAAQMD-established exposure criteria. Also, traffic generated by the proposed project would not result in, or contribute to, localized CO concentrations that would exceed the applicable NAAQS or CAAQS. Because implementation of Mitigation Measure AIR -1 from the Final SAPP would ensure that DPM emitted during project construction would not expose sensitive receptors to health risk s that would exceed BAAQMD -established criteria, this impact would be less than significant with mitigation . Because there would be no new significant impacts or substantially more severe impacts related to the exposure of sensitive receptors to substantial pollutant concentrations, the findings of the SAPP EIR remain valid, and no further analysis is required in a

supplemental or subsequent EIR. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts related to the exposure of sensitive receptors to substantial pollut ant concentrations that were analyzed in the SAPP EIR. d. Would the project result in other emissions (such as those leading to odors) that would adversely affect a substantial number of people?
The SAPP EIR recognized that the diesel-powered equipment and vehicles used during the demolition of existing land uses and the construction of new land uses would emit odorous diesel exhaust. However, such emissions would be short term and limited to the construction areas. The SAPP EIR determined that new land uses developed under the SAPP, including retail establishments, residential units, and office/commercial space, would not involve long-term operation of sources that would emit odorous emissions, which would be atypical in an urban environment. Therefore, the SAPP EIR determined that implementation of the SAPP would not result in objectionable odors that would adversely affect a substantial number of people. This impact would be less than significant.
The types of odor-emitting sources associated with the project’s short-term construction and demolition activities would be the same as those analyzed in the SAPP EIR. Odor-generating activities that would be part of project construction would not occur near off-site sensitive receptors for an extended period. Given the temporary and intermittent nature of construction activities, project construction is not anticipated to result in an adverse odor-related impact.
The office/commercial and retail land uses developed on the project site would not involve long- term operation of sources that would emit odorous emissions, which would be atypical in an urban environment, or the development of any major sources of odors (e.g., a landfill, wastewater treatment plant, dairy). Because there would be no new significant impacts or substantially more severe impacts related to odors, the findings of the SAPP EIR remain valid, and no further analysis is required in a supplemental or subsequent EIR. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts related to odors that were analyzed in the SAPP EIR.

The SAPP EIR found that impacts related to substantial adverse effects on candidate, sensitive, or special status species would be less than significant.
Because the project site and surrounding area are composed entirely of commercial, office, and residential developments and no sensitive natural community is present on the project site or within the Plan Area, the project site does not provide suitable foraging or breeding habitat for any special-status species. The wildlife species that would occur at the project site would be generalists Attachment 1

that have adapted to human-modified habitats. Therefore, the proposed project’s impacts associated with special-status species would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding special-status species that were analyzed in the SAPP EIR.
b. Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? The SAPP EIR found that impacts related to substantial adverse effects on aquatic, wetland, or riparian habitat or other sensitive natural community would be less than significant.
The project site and surrounding Plan Area are composed entirely of commercial, office, and residential developments. No riparian habitat or other sensitive natural community are present on the project site or in the immediate vicinity. In addition, the project would be required to implement the City’s standard stormwater Conditions of Approval (COA), such as FEP-05, Construction Sediment and Erosion Control Plan, and FEP-22, Stormwater Treatment (C.3), which would help to protect water quality and improve stormwater runoff. Therefore, the proposed project would have no impact associated with riparian habitat or other sensitive natural communities. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding riparian habitat or other sensitive natural communities that were analyzed in the SAPP EIR.
c. Would the project have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? The SAPP EIR found that impacts related to substantial adverse effects on state or federally protected wetlands would be less than significant.
No federally protected wetlands or other jurisdictional waters are present on the project site or in the immediate vicinity of the Plan Area. Any design features incorporated into the project site that would use water (e.g., bio-filtration planters) would be solely for landscaping purposes. No direct removal, filling, or hydrological interruption to state or federally protected wetlands would occur as a result of the project. As mentioned above, the project would be required to implement the City’s standard stormwater COAs, which would help protect water quality and any wetlands or bodies of water outside of the project site and Plan Area. Therefore, the proposed project would have no impact associated with state or federally protected wetlands. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding state or federally protected wetlands that were analyzed in the SAPP EIR. d. Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? The SAPP EIR found that impacts related to substantial adverse effects on candidate, sensitive, or special-status species would be less than significant.
As detailed above, no wetlands or running waters are present in the vicinity of the project site; therefore, the project would not affect fish movement. All project activities would occur within an already developed footprint surrounded by development. Therefore, the project would not result in Attachment 1

fragmentation within natural habitats that would interfere with the movement of wildlife. Any common urban-adapted species that currently move through the project site would continue to be able to do so following construction.
There are 2 2 existing trees on the project site. Of these trees, 1 3 would be removed, i ncluding five Heritage Trees, and nine trees would remain. Up to 1 9 additional trees would be planted throughout the project site, for a total of 2 8 trees onsite upon project completion . In addition, shrubs and ground cover would b e planted throughout the project site. If the project is implemented during the nesting season (February 1 –August 31), tree and structure removal could result in take (i.e., direct mortality of adult or young birds, the destruction of active nests, or disturbance of nesting adults , with associated nest abandonment or loss of reproductive effort). However, the project would be required to adhere to the City’s standard COAs, which include PL -198, Preconstruction Nesting Bird Survey . This COA requires that the project applicant conduct a survey of the project site using a qualified biologist, and if an active nest is identified, no-disturbance buffer zones will be established and maintained until the biologist determines the nest is n o longer active or the nesting season ends. With adherence to the City’s standard COAs, specifically those related to nesting birds, the project would not interfere with the movement of any species. Therefore, the proposed project’s impacts associated with the movement of any native resident or migratory fish or wildlife species would be less than significant . The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the movement of any native resident or migratory fish or wildlife species that were analyzed in the SAPP EIR. e. Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? The SAPP EIR found that impacts related to conflicts with local plans or ordinances protecting biological resources would be less than significant.
There are currently 22 trees on the project site, including five Heritage Trees. According to the San Antonio Precise Plan (Precise Plan), certain trees are subject to conditions before removal.
Construction activities associated with the project would remove 13 trees, including the five Heritage Trees, and preserve nine of the existing trees. In addition to the nine trees that would remain onsite, the project would plant an additional 19 trees at the project site. As described in Chapter 2, Project Description, the project includes a request for a Heritage Tree Removal Permit, which is subject to City review and approval with conditions. In addition, the project would be required to adhere to the City’s standard COAs related to trees, including the following:
l COA PL-134, Arborist Inspections, and COA PL-135, Monthly Arborist Inspections l COA PL-139, Replacement
l COA PL-141, Street Tree Protections
l COA PL-142, Tree Protection Measures
l COA PL-143, Security Bond
Adherence to the above-listed standard COAs would ensure that the project would comply with the City’s regulations regarding the removal of trees. To comply with COA PL-139, the loss of five Heritage Trees at the project site would be offset with the planting of 19 trees at the project site.
Each replacement tree would have a box no smaller than 24 inches, and the landscape plan would Attachment 1

include a note that states “Heritage Replacement Tree.” To comply with Standard COA PL-142, tree protection measures would be included as notes on the title sheet of all grading and landscape plans.
A Tree Removal Permit is part of the project application and would need to be approved pursuant to the policies and objectives set forth in the City’s ordinance regulating trees. With adherence to the above-referenced COAs and conformance with the necessary Tree Removal Permit, the project would not conflict with any local policies or ordinances that protect biological resources, such as a tree preservation policy or ordinance. Therefore, the proposed project’s impacts associated with conflicts with local policies or ordinances protecting biological resources would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding conflicts with local policies or ordinances that were analyzed in the SAPP EIR.
f. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? The SAPP EIR found that there would be no impacts related to conflicts with the provisions of an adopted Habitat Conservation Plan (HCP), Natural Community Conservation Plan (NCCP), or other approved local, regional, or state habitat conservation plans.
No adopted or proposed HCPs or NCCPs are applicable to the project site or Plan Area. The nearest area covered by an HCP, the Santa Clara Valley HCP, is approximately 9.5 miles south of the project site (Santa Clara Valley Habitat Agency 2021). Therefore, the proposed project would have no impact associated with conflicts with an adopted HCP, NCCP, or other approved local, regional, or state HCP. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding conflicts with adopted HCPs or NCCPs that were analyzed in the SAPP EIR.

3.3 Cultural Resources
Northwest Information Center Records Search
On April 20, 2021, ICF requested an updated records search for the proposed project from the Northwest Information Center (NWIC) in Rohnert Park, California, a part of the California Historic Resource Information System. NWIC returned results on May 5, 2021. They did not identify any resources within the project site, but four cultural resources were found within 0.5 mile of the project site, as listed in Table 3.3-1. No tribal cultural resources were found during Phases 1 and 2 of construction at the Village at San Antonio Center.
Table 3.3-1. Previously Recorded Archaeological Resources within 0.5 mile of the Project Site P-Number Trinomial Description
43-000021 CA-SCL-1 Castro Mound. This site was a prehistoric occupation site, originally 6–7 feet tall. Nelson (1910) described it as 500 feet (152.4 meters) long and 325 feet (99 meters) wide, but today only southernmost portions remain. Three to four hundred burials were found in this mound. Cultural material found includes shell, faunal bones, hearths, ground stone tools, and lithic flakes. A 2010 revisit failed to find the site (Chang 2015).
43-000042 CA-SCL-022 CA-SCL-022, also called the Little Castro, was described by L. L. Loud in 1912 as a small to moderately sized habitation site. The site’s dimensions at the time were 150 feet (45.7 meters) in diameter, at least 3 feet (0.9 meters) deep and 2.5 to 3 feet (0.8 to 0.9 meters) high. The site has been heavily disturbed, and no evidence of a mound currently exists, but Martinez and Moore observed shell and debitage in the soil during their 2010 field survey (Martinez and Moore 2010).

43-000595 CA-SCL-600 Originally described as a surface shell-laden midden scatter and a subsurface archaeological deposit containing burned rock, ground stone artifacts, flaked stone artifacts, and various types of shell measuring 984 feet by 492 feet (300 by 150 meters) by 3.3 feet (1 meter) thick. A 2010 field survey found that the site is no longer visible due to development, although evidence of subsurface midden deposits was found (Much 2015).
43-003172 Prehistoric midden measuring 3.3 feet (1 meter) north–south by 1.6 feet (0.49 meter) east–west and containing shell and groundstone.
This heavily disturbed site was recorded in 2010, incorrectly identified as P-43-000021 (Chang 2015).
a. Would the project cause a substantial adverse change in the significance of a historical resource pursuant to § 15064.5?
The SAPP EIR provided a programmatic-level analysis of the SAPP and explained that select built- environment resources (i.e., buildings, structures, objects, and districts) located within the plan area had been evaluated previously for historical significance and were determined not to qualify as significant historical resources under CEQA. Generally, pursuant to the CEQA Guidelines Section 15064.5(a), a historical resource requiring special consideration under CEQA would be one of the following: a resource meeting the eligibility requirements of the California Register of Historical Resources (CRHR); a resource included in a local register of historical resources; a significant resource identified in a qualifying local survey; or a resource otherwise treated as significant by the CEQA lead agency.
However, the SAPP area was not subject to a comprehensive historical resource survey and inventory at the time the SAPP EIR was prepared, and it contains additional built-environment resources that had reached historic age (generally, 50 years old), but had not been evaluated for listing in the local historical register, CRHR, or National Register of Historic Places (NRHP). As such, it remained unknown whether any built-environment resources in the SAPP area qualified as significant historical resources requiring consideration during CEQA review. The SAPP EIR noted, however, that the City of Mountain View 2030 General Plan (General Plan) and General Plan EIR contained the following actions applicable to built-environment resources:
l ACTION Land Use Designation (LUD) 11.1.1: Register of Historic Resources. Maintain and update the Mountain View Register of Historic Resources. l ACTION LUD 11.1.3: Historic resource changes. Utilize the development review process to ensure that changes to historic resources are consistent with the U.S. Secretary of Interior Standards for the Treatment of Historic Properties.
l ACTION LUD 11.3.1: Early historic evaluation. Identify and evaluate historic and cultural resources early in the development review process.
The SAPP EIR also invoked three of the City of Mountain View’s (City) conditions of approval:
l COA PL-161, Secretary of the Interior Standards
l COA PL-162, Documentation of Historic Resource
l COA PL-163, Salvage Program

Tribal Cultural Resources
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.3-3 February 2022 ICF 104340.0.001.01
The SAPP EIR stated that the impacts of projects resulting from the SAPP would be analyzed during future project-level review. Action LUD 11.3.1, Early historic evaluation, specifically identifies the need to evaluate the CEQA historical resource status of historic-aged built-environment resources that may be altered or demolished by future proposed projects. The SAPP EIR concluded that the need for future project-level review, as supported by the application of the three General Plan actions and three COAs, ensured that the SAPP would not cause substantial adverse change in the significance of any historical resource pursuant to PRC Section 15064.5, and its impact to historical resources would be less than significant.
The project site, which lies within the boundaries of the SAPP area, contains two buildings; both are now more than 50 years old, meaning they have the potential to qualify as CEQA historical resources:
365 San Antonio Road (assessor’s parcel number [APN] 148-22-005), constructed in 1952, and 2585 California Street (APN 148-22-007), constructed in 1961.1 Neither building has been previously evaluated for CRHR or NRHP listing or otherwise considered for CEQA historical resource status.
Furthermore, no buildings immediately adjacent to the project site appear to be of historic age.2 Pursuant to General Plan Action LUD 11.3.1, the buildings at 365 San Antonio Road and 2585 California Street were evaluated for CRHR and NRHP listing. ICF completed an intensive-level historical resources survey of both buildings. The buildings’ physical characteristics, historic context, site history, and NRHP/CRHR evaluations were documented on Department of Parks and Recreation (DPR) 523A (Primary Record) and 523B (Building, Structure, Object) forms, which are included in Appendix B.
Based on these evaluations, neither historic-aged building located within the project site is eligible for NRHP or CRHR listing because of the lack of significance under NRHP/CRHR evaluative criteria. As a result, neither building meets the requirements of a historical resource presented in the CEQA Guidelines Section 15064.5(a); construction of the project would thus not impair the significance of a significant built-environment historical resource materially. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with built-environment historical resources would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding built-environment historical resources that were analyzed in the SAPP EIR.
b. Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to § 15064.5?
The SAPP EIR found that impacts related to substantial adverse changes in the significance of an archaeological resource pursuant to PRC Section 15064.5 would be less than significant.
As discussed previously, there is a potential for significant historic-period archaeological deposits to occur, given the history of development along the El Camino Real corridor portion of the SAPP area.
Construction of the proposed project would include activities such as demolition, excavation, and foundation and building construction, which have the potential to destroy prehistoric and historical archaeological deposits, including previously unidentified subsurface deposits.
1 T he street addresses used in this section, as well as the appended Department of Parks and Recreation (DPR) forms, refer to the addresses historically assigned to the two buildings within the project site. The parcel containing 2585 California Street currently bears the address 2585–2595 California Street, which is utilized in other sections of this Addendum.
2 The records search results also included several built-environment resources. However, none of those resources is located within or adjacent to the project site. Because the previously identified built-environment resources have low impact potential due to their physical distance from the project site, they are not discussed in this impact analysis.

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.3-4 February 2022 ICF 104340.0.001.01
The General Plan and General Plan EIR identified the following policies and actions to address potential impacts to archaeological deposits:
l ACTION LUD 11.3.1: Early historic evaluation. Identify and evaluate historic and cultural resources early in the development review process.
l POLICY LUD 11.5: Archaeological and paleontological site protection. Require all new development to meet state codes regarding the identification and protection of archaeological and paleontological deposits.
l ACTION LUD 11.5.1: Review Historic Property Directory List. Prior to approval of development permits for projects that include ground-disturbing activities, City staff will review the most recent and updated NWIC list, Historic Property Directory for the County of Santa Clara, to determine if known archaeological and paleontological sites underlie the proposed project. If it is determined that known cultural resources are within one-quarter mile of the project site, the City will require the project applicant to conduct an NWIC records search at Sonoma State University to confirm whether there are any recorded cultural resources within or adjacent to the project site. Based on that research, the City will determine whether field study by a qualified cultural resources consultant is recommended. l ACTION LUD 11.5.2: Pre-construction cultural resource surveys. Should City staff determine that field study for cultural resources is required, the project applicant will have a cultural resource professional meeting the Secretary of the Interior’s Standards in history or archaeology conduct a preconstruction survey to identify significant cultural resources—including archaeological sites, paleontological resources, and human remains—in the project site and provide project- specific recommendations, as needed. Coordination with local Native American communities should be performed when significant cultural resources and remains are identified as part of pre-approval site analysis.
City staff has determined no field survey for the proposed project is necessary per Action LUD
11.5.2. In addition, the project would comply with Standard COA PL-194, which pertains to the discovery of archaeological resources during ground-disturbing activities.
The SAPP EIR found that impacts related to tribal cultural resources would be less than significant.
The General Plan and General Plan EIR policies and actions listed above that pertain to archeological resources and below that pertain to human remains also apply to tribal cultural resources.
Additionally, the project would comply with Standard COA PL-195, which pertains to the discovery of human remains during ground-disturbing activities, which would also protect tribal cultural resources.
Therefore, the proposed project’s impacts associated with archaeological and tribal cultural resources would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding archaeological resources and tribal cultural resources that were analyzed in the SAPP EIR. c. Would the project disturb any human remains, including those interred outside of dedicated cemeteries?
The SAPP EIR found that impacts related to disturbance of any human remains, including those interred outside of dedicated cemeteries, would be less than significant by adhering to the following mitigation measures. Typically, such human remains are associated with prehistoric archaeological habitation sites, (e.g., shell middens). As discussed previously, the city includes several recorded Attachment 1

prehistoric archaeological deposits, including those that contain Native American human remains.
Construction of the proposed project would include activities such as demolition, excavation, and foundation and building construction, which have the potential to destroy prehistoric archaeological deposits that may include associated human remains.
The General Plan and General Plan EIR identified the following policies and actions to address potential impacts to human remains:
l POLICY LUD 11.6: Protect Human Remains. Utilize the development review process to identify and protect human remains and follow the appropriate procedures outlined under Health and Safety Code Section 7050.5 and PRC Section 5097.98.
l ACTION LUD 11.6.1: Human Remains. Should human remains be found on a project site, no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains will be disturbed until the Santa Clara County Coroner is contacted and determines that no investigation of the cause of death is required. If an investigation is required, and the coroner determines the remains to be Native American, then: (1) the coroner would contact the Native American Heritage Commission within 24 hours; (2) the Native American Heritage Commission would identify the person or persons it believes to be the most likely descended from the deceased Native American; and (3) the most likely descendent may make recommendations to the landowner or the person responsible for the excavation work, for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in PRC Section 5097.98.
In addition, the project would comply with Standard COA PL-195, which pertains to the discovery of human remains during ground-disturbing activities. Therefore, the proposed project’s impacts associated with human remains would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding human remains that were analyzed in the SAPP EIR.

The proposed project would demolish two single-story commercial buildings and associated surface parking and construct a commercial building with open spaces and a below-grade parking garage. The proposed project would comply with existing regulations, standards, requirements, as well as COAs and policies listed above. In addition, the proposed project would not exacerbate risk of surface fault rupture. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with surface fault rupture would be less than significant.
The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding surface fault rupture that were analyzed in the SAPP EIR. ii. Strong seismic ground shaking?
The SAPP EIR concluded that impacts related to strong seismic ground-shaking as a result of earthquake would be less than significant. Although major regional faults located near city are capable of producing very strong to violent ground-shaking within the SAPP area, existing federal, state, and local regulations, programs, and standards provide current information detailing seismic hazards and impose regulatory requirements regarding geotechnical and soils investigations. New development associated with the SAPP is required to comply with these regulations and requirements.

iii. Seismic-related ground failure, including liquefaction? The SAPP EIR concluded that impacts related to seismic-related ground failure, including liquefaction, would be less than significant. Although the SAPP area is underlain by materials with a moderate liquefaction potential, federal, state, and local regulations, programs, and standards provide current information detailing seismic hazards and impose regulatory requirements regarding geotechnical and soils investigations. New development associated with the SAPP is required to comply with these regulations and requirements.

Compliance with these regulations, standards, requirements, COAs, and policies would reduce impacts relative to seismic-related landslide to less than significant.
The proposed project would demolish two single-story commercial buildings and associated surface parking and construct a commercial building with open spaces and a below-grade parking garage. The proposed project would comply with existing regulations, standards, requirements, as well as COAs and policies listed above. In addition, the proposed project would not exacerbate risk of seismic-related landslide. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with seismically induced landslide would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding seismically induced landslide that were analyzed in the SAPP EIR.
b. Would the project result in substantial soil erosion or the loss of topsoil? The SAPP EIR concluded that impacts related to substantial soil erosion or loss of topsoil would be less than significant. Construction associated with development or redevelopment under the SAPP could include activities that would cause erosion, decrease in water quality, and loss of topsoil.
Development in the city is subject to existing regulations, including Section 35.32.10 of the City of Mountain View Municipal Code, that require all development projects to be conducted in a manner that prevents stormwater pollution. In addition, all development resulting from implementation of the SAPP would be required to comply with identified stormwater policies and COAs, listed below. l General Plan policies and actions
¡ Policy INC 8.2: National Pollutant Discharge Elimination System Permit. Comply with requirements in the Municipal Regional Stormwater National Pollutant Discharge Elimination System Permit (MRP).
¡ Policy INC 8.4: Runoff pollution prevention. Reduce the amount of stormwater runoff and stormwater pollution entering creeks, water channels and the San Francisco Bay through participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program.

¡ Policy INC 8.5: Site-specific stormwater treatment. Require post-construction stormwater treatment controls consistent with MRP requirements for both new development and redevelopment projects.
l Applicable COAs
¡ FEP-03. State of California Construction General Stormwater Permit: A "Notice of Intent" (NOI) and "Stormwater Pollution Prevention Plan" (SWPPP) shall be prepared for construction projects disturbing one (1) acre or more of land. Proof of coverage under the State General Construction Activity Stormwater Permit shall be attached to the building plans. ¡ FEP-04. Construction Best Management Practices: All construction projects shall be conducted in a manner which prevents the release of hazardous materials, hazardous waste, polluted water, and sediments to the storm drain system. Refer to the City of Mountain View document, "It's In the Contract But Not In the Bay," for the specific construction practices required at the job site.
¡ FEP-05. Construction Sediment and Erosion Control Plan: The applicant shall submit a written plan acceptable to the City which shows controls that will be used at the site to minimize sediment runoff and erosion during storm events. The plan should include installation of the following items where appropriate: (a) silt fences around the site perimeter; (b) gravel bags surrounding catch basins; (c) filter fabric over catch basins; (d) covering of exposed stockpiles; (e) concrete washout areas; (f) stabilized rock/ gravel driveways at points of egress from the site; and (g) vegetation, hydroseeding, or other soil stabilization methods for high-erosion areas. The plan should also include routine street sweeping and storm drain catch basin cleaning.
Compliance with these regulations, standards, requirements, COAs, and policies would reduce the potential for substantial erosion and loss of topsoil to less than significant.
The proposed project would involve ground-disturbing activities, including grading and excavation.
These activities potentially could result in substantial erosion. However, the proposed project would be subject to the same regulations and COAs identified in the SAPP EIR. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with substantial soil erosion or loss of topsoil would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding substantial soil erosion or loss of topsoil that were analyzed in the SAPP EIR. c. Would the project be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? The SAPP EIR concluded that impacts related to project location on a geologic unit or soil that is unstable or would become unstable as a result of the project would be less than significant. Because of the low relief of local topography, potential impacts related to landslide also would be less than significant. New development associated with the SAPP would involve use of water managed by Santa Clara Valley Water District, which receives a portion of its water supplies from groundwater.
In addition, new development associated with the SAPP would have a risk of collapse of trench walls and construction on materials with moderate liquefaction potential. However, the SAPP EIR also identified COAs, including a requirement to complete a geotechnical investigation and a soils report to identify and mitigate geologic and soils hazards in project site design, and General Plan policies and actions relevant to subsidence, collapse, liquefaction, and lateral spreading.

l Applicable COAs
¡ PL-48 Geotechnical Report.
Adherence to these COAs and General Plan policies would reduce impacts related to subsidence, collapse, liquefaction, and lateral spreading to less than significant.
The proposed project would involve increased water demand, excavation that could create steep earthen walls, and construction on materials subject to liquefaction and lateral spreading. The proposed project would comply with the same existing regulations, standards, requirements, as well as COAs and policies listed above as the SAPP. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with unstable geologic units or soils would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding unstable geologic units or soils that were analyzed in the SAPP EIR.
d. Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? The SAPP EIR concluded that impacts related to location of a project on expansive soil would be less than significant. Soils in the SAPP area have been identified as having a moderate to high shrink/swell potential. Implementation the following COAs would reduce this potential impact to less than significant.

The proposed project would also locate construction on expansive soil. The proposed project would comply with the same COAs listed above identified in the SAPP EIR. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with expansive soil would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding expansive soil that were analyzed in the SAPP EIR.
e. Would the project have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?
The SAPP EIR concluded that there would be no impact related to soils incapable of adequately supporting the use of septic tanks or alternative wastewater systems. The approved project is serviced by a sanitary sewer system operated by the City.
The proposed project would demolish two single-story commercial buildings and associated surface parking and construct a commercial building with open spaces and a below-grade parking garage.
As with the approved project, these facilities would be serviced by the City’s sanitary sewer system.
Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with use of septic tanks or alternative wastewater disposal systems would be no impact.
The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding use of septic tanks or alternative wastewater disposal systems that were analyzed in the SAPP EIR.
f. Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
The SAPP EIR concluded that impacts related to a paleontological resource or site would be less than significant with adherence to COAs and General Plan policies and actions. Although no paleontological resources have been recovered in the city, geologic units underlie the SAPP area that are known to contain fossils, indicating paleontological sensitivity. The SAPP EIR identified several policies and actions in the General Plan that would apply to new development resulting from implementation of the SAPP, listed below.
l General Plan policies and actions
¡ Action LUD 11.3.1: Early historic evaluation.
¡ Policy LUD 11.5: Archaeological and paleontological site protection. Require all new development to meet state codes regarding the identification and protection of archaeological and paleontological deposits.
¡ Action LUD 11.5.1: Review Historic Property Directory List. ¡ Action LUD 11.5.2: Pre-construction cultural resource surveys. ¡ Action LUD 11.5.3: Archaeological and paleontological standard conditions.
Compliance with these General Plan policies and actions would reduce impacts on paleontological resources and unique geologic features.
To accommodate construction of building foundations and a below-ground parking garage, the project would excavate to a maximum depth of approximately 55 feet (16.8 meters) below the ground surface, resulting in the export of approximately 55,350 cubic yards of soil. As identified in Attachment 1

the SAPP EIR, the geologic unit underlying the project site is sensitive for paleontological resources.
The geologic unit underlying the project site is Quaternary Alluvium (Wagner et al. 1991), which is sensitive for paleontological resources, having yielded fossils of Mammuthus (mammoth), Bison (bison), Equus (horse), and others (Maguire and Holroyd 2016). The proposed project would comply with the same COAs and policies and actions identified in the General Plan and listed above as the approved project. Therefore, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with paleontological resources would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding paleontological resources that were analyzed in the SAPP EIR.

3.5 Greenhouse Gas Emissions
a. Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
The SAPP EIR found that impacts related to greenhouse gases (GHG) would be less than significant, because the SAPP would be consistent with the City’s Greenhouse Gas Reduction Plan (GGRP).
The project would result in the development of a new seven-story building and proposes a change in the limit of office development in the Northwest San Antonio Master Plan. The total office development limit would not change and would remain 600,000 gsf in the SAPP. Consequently, the project would not result in any substantial changes in GHG emissions from the buildout of the SAPP, because the distribution of office space within the SAPP sub -areas would not appreciably affect the level of GHG emissions. Construction of the seven-story building and the increase in the office development limit in the Northwest San Antonio Master Plan would generate a comparable amount of GHG emissions as the buildout as evaluated in the SAPP EIR because the type of construction activities and equipment would be similar . In addition, the types and magnitude of activities that generate operational GHG emissions for the project would also be similar to those analyzed in the SAPP EIR. In general, office development would result in emissions from building energy consumption, water consumption, waste generation, and on -road vehicle travel. Some emissions occur onsite (e.g. , natural gas- and motor vehicle -related emissions ), but those emissions enter into the atmosphere and disperse globally. Thus, if those emissions are emitted in the Northwest San Antonio Master Plan instead of elsewhere in the SAPP, it does not measurably change the contribution to climate change that was evaluated in the SAPP EIR. Furthermore, as noted in Section 3.13, Transportation and Traffic , the project site is within a 0.5 -mile walk of rail and transit stops, which, according to California Public Resources Code Section 21155, indicates that the project is within 0.5 miles of a major transit stop. The City’s vehicle miles traveled ( VMT) policy establishes screening criteria for developments, based on CEQA Guidelines Section 15064.3(b)(1), and concludes that certain projects within 0.5 mile of an existing major transit stop or an existing stop along a high -quality transit corridor will ha ve a less-than-significant impact on VMT. The project would meet the City’s VMT reduction target, which was designed to meet statewide VMT and, thus, statewide GHG reduction goals, mobile source emissions from on- road vehicles. Reducing VMT is a key element of the state’s strategy for reducing GHG emissions.

Section 3.5, Greenhouse Gas Emissions
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.5-2 February 2022 ICF 104340.0.001.01
Emissions from other sectors would be minimized through project features and compliance with statewide regulatory programs. For example, the project would be compliant with Leadership in Energy and Environmental Design (LEED) Gold and reduce water and energy consumption through low-flow fixtures and energy-efficient appliances. Waste at the project site would be diverted as much as possible through recycling and organics (i.e., compost) collection, which would reduce methane emissions from waste decomposing anaerobically in landfills. The project’s electricity demand would come from progressively lower carbon sources, as the state’s energy suppliers comply with the requirements of the Renewable Portfolio Standards. As such, in addition to being consistent with the City’s GGRP, the project’s emissions would be minimized by and compliant with applicable regulatory programs, such that emissions would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the generation of GHG emissions that may have a significant impact that were analyzed in the SAPP EIR. b. Would the project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
In 2012, the City adopted the 2030 Mountain View General Plan (General Plan), which included the GGRP (City of Mountain View 2012) to mitigate the emissions associated with future development allowed under the General Plan. The GGRP identifies a series of GHG emissions reduction measures to be implemented by development projects that would allow the City to achieve its GHG reduction goals. The measures center around five strategy areas: energy, waste, water, transportation, and carbon sequestration.
The GGRP was considered to be a qualified GHG reduction plan pursuant to CEQA Guidelines Section 15183.5 because, among other attributes, it was adopted in a public process following environmental review provided in the City’s 2030 General Plan and Greenhouse Gas Reduction Program EIR (City of Mountain View 2014). As noted above, the construction of a seven-story building and a change to the office space limit in the Northwest San Antonio Master Plan would not appreciably change the level of emissions relative to those evaluated in the SAPP EIR because the type of land use (e.g., office space) and amount of land use (e.g., 600,000 gsf) would be unchanged.
As such, implementation of the project would not cause a new conflict with any plan, policy, or regulation that was not identified in the SAPP EIR and this impact would be less than significant.
The proposed project would not result in new conflicts with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of GHGs or a substantial increase in the severity of impacts regarding such plans, policies, or regulations that were analyzed in the SAPP EIR.

and actions and applicable COAs. The SAPP EIR concluded that compliance with federal, state, and local requirements, General Plan policies and associated actions, and implementation of applicable COAs, would reduce the potential for impacts related to the use and handling of hazardous materials to a less-than-significant level.
The project proposes demolition of two single-story commercial buildings and associated surface parking and construction of a commercial building with open spaces and a below-grade parking garage. Thus, implementation of the proposed project would result in construction activities that would require the routine transport, use, or disposal of hazardous materials and hazardous wastes.
If accidentally released, these materials could result in exposure risks for construction personnel and nearby residents. Similar to the analysis in the SAPP EIR, transport, use, and disposal of hazardous materials would comply with applicable federal and state regulations, such as the Resource Conservation and Recovery Act and Department of Transportation Hazardous Materials Regulations. In addition to compliance with the aforementioned regulations, the implementation of applicable General Plan policies (such as Policy PSA 3.2: Protection from hazardous materials, POLICY PSA 3.3: Development review) and COAs would also be required. Applicable COAs to the transport, use, or disposal of hazardous materials are as follows:
l COA BID-15 Hazardous Materials
l COA HAZ-02 Hazardous Materials
l COA HAZ-03 Installation or Upgrade of Hazardous Materials Storage Because the proposed project involves office and retail uses, hazardous materials used during operations are expected to consist of common cleaners and other materials used for day-to-day maintenance. These materials are generally used in small quantities, and any spills generally are cleaned up as they occur. Therefore, impacts associated with the routine transport, use, or disposal of hazardous materials would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with the routine transport, use, or disposal of hazardous materials that were analyzed in the SAPP EIR. b. Would the project create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?
According to the SAPP EIR, hazardous material contamination from existing hazardous material release sites or hazardous building materials in buildings to be demolished could affect human health and the environment. The severity of health effects would depend on the contaminant(s), concentration, use of personal protective equipment, institutional controls, engineering controls, and duration of exposure. The disturbance and release of these materials during construction could pose an exposure risk to construction workers, nearby receptors, and the environment. The SAPP EIR concluded that compliance with General Plan policies and associated actions and implementation of applicable COAs would reduce the potential for impacts related to upset and accident conditions involving the release of hazardous materials to a less-than-significant level.
Applicable COAs are as follows:
l COA PL-49 Toxic Assessment
l COA PL-193 Discovery of Contaminated Soils

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.6-3 February 2022 ICF 104340.0.001.01
A Phase I ESA was prepared for the proposed project by Roux Associates, Inc. in July of 2020. The purpose of the Phase I ESA was to identify Recognized Environmental Conditions (RECs)1 in connection with the project site. Only one REC was identified in connection to the project site:
l Former Shell Station 2595 California Street. A former Shell station located within the project site at 2595 California Street was listed as a closed Leaking Underground Storage Tank (LUST) case with a gasoline release to groundwater. According to the Phase I ESA, all structures associated with the Shell site were removed, and the remaining hydrocarbon plume was limited to beneath the former station. Remediation, which involved soil excavation, vapor extraction, and groundwater extraction, was conducted and the case received closure in 2003. At the time, residual concentrations of contaminants were concluded to potentially pose an unacceptable risk for some site development activities. However, a Construction Management Plan (CMP) was prepared in 2020 and contained mechanisms to address the residual contaminants onsite.
Specifically, the CMP identifies Risk Management Measures (those addressing potential impacts related to worker health and safety, stormwater pollution prevention, construction dewatering and vapor intrusion) along with guidance for soil management and management of unknown subsurface structures uncovered during construction. The CMP was dated April 6, 2020, and was included as an appendix to the July 2020 Phase I ESA prepared by Roux Associates, Inc. This REC associated with the former Shell station at 2595 California Street was considered resolved in the Phase I ESA.
In addition to the REC, four Business Environmental Risks (BERs) were identified with the project site.
BERs are conditions that generally do not present a threat to human health or the environment and generally would not be the subject of an enforcement action; however, these conditions may have a material environmental or environmentally driven impact. As presented in the Phase I ESA, they include:
l Nearby closed LUST cases: At the time of the Phase I ESA’s preparation, there were multiple closed LUST cases and a closed Cleanup Program case in the vicinity of the project site, related to gasoline in groundwater and waste oil/motor oil/hydraulic oil/lubricating oil in soil. l Adjacent gas station with multiple violations: A Valero gas station located at 334 San Antonio Road has received multiple violations from the Mountain View Fire Department related to the lack of care in handling and storage of hazardous materials. However, there were no records of any significant releases to onsite soil or groundwater.
l Agricultural pesticide use. The project site was used for agricultural purposes between at least 1939 and at least 1950. According to the Phase I ESA, historic pesticide use on the project site may have caused impacts.
l Potential asbestos use. Based on the construction date of onsite structures, the Phase I ESA identified the possibility of asbestos containing building materials.
Because potential impacts associated with the proposed project involve residual contamination (in the form of a hydrocarbon release to groundwater and residual pesticides) and the potential existence of hazardous building materials (hazardous materials risks previously analyzed in the SAPP EIR),
1 American Society for Testing Materials (ASTM) Standard Practice E1527-13 defines RECs as the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions.

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.6-4 February 2022 ICF 104340.0.001.01
compliance with General Plan policies and associated actions (such as Policy INC 18.1: Contamination prevention, Policy INC 18.2: Contamination clean-up and Policy PSA 3.4: Oversight agencies), along with implementation of applicable COAs, including COA PL-193 Discovery of Contaminated Soils and COA PL- 49 Toxic Assessment, would reduce potential exposure risks of these materials during project construction. Furthermore, implementation of the Construction Management Plan for The Village at San Antonio Center – Block 3 prepared in 2020 would include mechanisms to address the potential for residual contamination associated with the former Shell station. Therefore, impacts associated with reasonably foreseeable upset and accident conditions involving the release of hazardous materials would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with reasonably foreseeable upset and accident conditions involving the release of hazardous materials that were analyzed in the SAPP EIR. c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? The SAPP EIR identified that children are more susceptible to health effects from exposure to hazardous materials, substances, and waste than adults. As such, prospective school sites should be reviewed to determine that such sites are not contaminated by hazardous materials or located within a quarter-mile of land uses that manage substantial quantities of hazardous materials. California Education Code Sections 21151.2, 21151.4, and 21151.8 specifically require investigation of prospective school sites in accordance with Department of Toxic Substances Control guidance.
Adherence to existing regulatory requirements and applicable General Plan policies and associated actions would reduce the potential for school children to be exposed to hazardous or acutely hazardous materials to a less-than-significant level.
There are no schools within one-quarter mile of the proposed project site, and, thus, impacts associated with hazardous emissions or the handling of hazardous or acutely hazardous materials near a school would not occur. There would be no impact. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding hazardous emissions and materials near an existing or proposed school that were analyzed in the SAPP EIR. d. Would the project be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
According to the SAPP EIR, the SAPP area contained several contaminated sites in varying states of remediation, including sites within the Cortese List. Direct contact, inhalation, or ingestion of hazardous materials associated with Cortese List sites could potentially cause adverse health effects to construction workers and future site users. The severity of health effects would depend on the contaminant(s), concentration, use of personal protective equipment, institutional controls, engineering controls, and duration of exposure. The disturbance and release of hazardous materials during construction activities, if present, could pose a hazard to construction workers, nearby receptors, and the environment. The SAPP EIR concluded that compliance with General Plan policies and associated actions and implementation of applicable COAs would reduce the potential for impacts related to Cortese List sites to a less-than-significant level. Applicable COAs are as follows:
l COA PL-49 Toxic Assessment
l COA PL-193 Discovery of Contaminated Soils

The former Shell station at 2595 California Street (discussed in detail under threshold b.) was listed in the LUST database and is also part of the Cortese List. Similar to what was described in threshold b., compliance with General Plan policies and associated actions (such as Policy INC 18.1:
Contamination prevention, Policy INC 18.2: Contamination clean-up and Policy PSA 3.4: Oversight agencies) along with implementation of applicable COAs would reduce potential exposure risks associated with onsite contaminants during project construction. Furthermore, implementation of the Construction Management Plan would be used to address the potential residual contamination associated with the aforementioned Shell station. Therefore, impacts associated with the project site being located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5 would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding hazardous materials sites compiled pursuant to Government Code § 65962.5 that were analyzed in the SAPP EIR.
e. Would the project for a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area?
The SAPP EIR determined that the SAPP area is not located within any protected airspace zones defined by the Airport Land Use Commission and has no heliports listed by the Federal Aviation Administration. No impact would occur.
Because the project site is within the SAPP area, potential airport impacts associated with the proposed project also would not occur. Therefore, the proposed project would have no impact related to airports. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding airports that were analyzed in the SAPP EIR. f. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
General Plan policies require ongoing maintenance of existing emergency response plans, development of a new emergency response plan for damaged utilities, development of a Local Hazard Mitigation Plan, emergency response training, and collaboration with local communities, large employers, and Moffett Federal Airfield to coordinate emergency response and preparedness within the city. The SAPP EIR determined that increased traffic as a result of new development in the SAPP area could impair emergency response and evacuation procedures. However, the implementation of applicable General Plan policies and associated actions would reduce potential impacts related to impairment or interference with emergency response plans or emergency evacuation plans to a less-than-significant level.
All development associated with the proposed project would also be subject to applicable General Plan policies and associated actions, including policies that require the maintenance of efficient automobile infrastructure and effective Transportation Demand Management (TDM) programs such as: Policy MOB 10.1: Efficient automobile infrastructure, Policy MOB 10.2: Reducing travel demand and Policy MOB 10.4: Emergency response to reduce potential impacts to local emergency response and evacuation procedures. Therefore, potential impacts associated with the proposed project impairing or interfering with an adopted emergency response plan or emergency evacuation plan would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding an adopted emergency response plan or emergency evacuation plan that were analyzed in the SAPP EIR.

g. Would the project expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? According to the analysis found in the SAPP EIR, there are no California Department of Forestry and Fire Protection’s (CAL FIRE) Fire Hazard Severity Zones for state responsibility areas or Very High Fire Hazard Severity Zones for local responsibility areas within or adjacent to the SAPP area. As such, the SAPP EIR concluded that impacts related to wildland fire hazards on new development or redevelopment in the SAPP area would not occur. There would be no impact.
Because the project site is within the SAPP area, impacts related to wildland fires would also not occur. Therefore, the proposed project would have no impact related to wildland files. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding wildland fires that were analyzed in the SAPP EIR.

3.7 Hydrology and Water Quality
a. Would the project violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? The SAPP EIR concluded that impacts that would violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality would be less than significant. Development associated with the approved project is subject to existing water quality regulations and programs that establish water quality standards and provide enforcement. New development associated with the approved project are required to comply with these regulations and programs. The SAPP EIR identified several policies and actions in the General Plan including INC 8.2 (National Pollutant Discharge Elimination System Permit), INC 8.4 (Runoff pollution prevention), INC 8.5 (Site-specific stormwater treatment), and INC 8.7 (Stormwater quality), as well as applicable COAs including COA FEP-05 (Construction Sediment and Erosion Attachment 1

Control Plan) and COA FEP-22 (Stormwater Treatment [C.3]), which require compliance with surface water and groundwater quality standards and waste discharge requirements. Therefore, the SAPP EIR concluded impacts to be less than significant.
The project proposes demolition of two single-story commercial buildings and associated surface parking and construction of a commercial building with open spaces and a below-grade parking garage. The proposed project would be required to comply with the water quality regulations and programs identified in the General Plan EIR, including the existing National Pollutant Discharge Elimination System (NPDES) permits for construction and post-construction, applicable General Plan policies, and COAs. The proposed project would also be required to comply with Municipal Regional Permit (MRP) Provision C.3, which requires that new development mitigate impacts on water quality by incorporating low impact development (LID) measures, including pollutant source control, stormwater treatment, and flow control measures. LID treatment measures include “capture and re-use” or rainwater harvesting, infiltration, bio-retention basins or flow-through planters, and green roofs. Project features, including planter boxes and a LID-based treatment system, would be used to treat stormwater runoff from the roof of the proposed building.
Furthermore, proprietary biofiltration units and non-LID treatment systems would be used to treat ground-level stormwater runoff. Thus, implementation of the proposed project would not violate any water quality standards or waste discharge requirements. Therefore, no impacts associated with water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality would occur. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding water quality standards or waste discharge requirements or impacts related to otherwise substantially degrading surface or ground water quality that were analyzed in the SAPP EIR. b. Would the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?
The SAPP EIR concluded that impacts associated with groundwater supplies and recharge would be less than significant.
The City’s groundwater resources are located within the Santa Clara subbasin (Subbasin No. 2-9.02) (RWQCB 2017). The proposed project is within the service area of Santa Clara Valley Water District (SCVWD) and would not rely on groundwater supplies as a source for water. Development associated with the proposed project would result in an increase in impervious surface, covering recharge areas which would reduce groundwater aquifer recharge. However, the project site is in a developed area with minimal land facilitation of groundwater recharge. Therefore, impacts associated with groundwater supplies and recharge would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding groundwater supplies and recharge that were analyzed in the SAPP EIR. c. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i. Result in a substantial erosion or siltation on- or offsite? The SAPP EIR concluded that impacts associated with altering the existing drainage pattern and erosion or siltation on- or offsite would be less than significant.

Section 3.7, Hydrology and Water Quality
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.7-3 February 2022 ICF 104340.0.001.01
Construction of the proposed project would comply with existing stormwater regulations and post-construction stormwater requirements under the NPDES Order No. 2009-0009 DWG and NPDES Order No. R2-2009-0074 and requirements outlined in the stormwater pollution prevention plan (SWPPP) prepared for the approved project. Furthermore, existing stormwater regulations regarding construction and post-construction stormwater requirements include extensive requirements for new development, reflected in applicable COAs (COA FEP-05 Construction Sediment and Erosion Control Plan), with which the proposed project would comply. Therefore, impacts associated with altering the existing drainage pattern that could result in erosion or siltation would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with altering the existing drainage pattern that could result in erosion or siltation that were analyzed in the SAPP EIR.
ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or offsite?
The SAPP EIR concluded that impacts associated with an increase in the rate or amount of surface runoff in a manner which would result in flooding on- or offsite would be less than significant.
Impervious surfaces associated with the proposed project would increase over existing conditions, which could result in an increased amount of runoff. Structural or Treatment Control best management practices (BMPs) would be required for the proposed project. Construction of the proposed project would involve activities that may temporarily alter drainage patterns.
However, these activities are temporary, and the proposed project would adhere to the SWPPP prepared for the approved project, which would reduce potential impacts on drainage patterns or result in flooding. After project construction is complete, drainage patterns would be similar to existing conditions. The proposed project would not significantly alter established drainage patterns or significantly increase the amount of runoff. Furthermore, the proposed project would be designed to include features that would capture runoff. Roof runoff would be discharged from roofs via downspouts into volume-based planter boxes, and planter boxes would be sized adequately to detain and treat the required volume. In addition, proprietary biofiltration units (modular wetlands) would manage stormwater runoff from ground level areas. Further, compliance with General Plan policies INC 8.4 (Runoff pollution prevention) and INC 8.7 (Stormwater quality) would reduce the volume of stormwater runoff. Therefore, impacts would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with runoff that were analyzed in the SAPP EIR.
iii. 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?
The SAPP EIR concluded that impacts associated with runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff would be less than significant.
Construction activities and operation of the proposed project have the potential to introduce contaminants to stormwater. However, the proposed project would be required to comply with existing NPDES permits for construction and post-construction, as well as compliance with Attachment 1

applicable General Plan policies. High capacity bio-filtration BMPs would be utilized for stormwater treatment. The proposed project would increase the amount of impervious surface by approximately 4,315 square feet. The increase in impervious surface could increase stormwater runoff rates and volumes, potentially resulting in degradation of water quality in receiving waters; however, the project is exempt from hydromodification management requirements. Planter boxes, a LID-based treatment system, would be used to treat roof runoff from the building and proprietary biofiltration units (modular wetlands), non-LID treatment systems, will be used to treat ground- level areas. Ground-level surface runoff would enter the modular wetland biofiltration units and discharge to the City’s storm drain system. The project would rely on the Adopted California BMP Handbook method for volume-based calculations and the Uniform Intensity Approach for flow- based calculations. Further, Mitigation Measure UTL-3 requires a project-specific analysis of the stormwater infrastructure adjacent and downstream of the project site to identify any impacts to the stormwater system and determine if any upgrades or improvements to the City’s stormwater infrastructure are required. Therefore, impacts associated with the capacity of existing or planned stormwater drainage systems or additional sources of polluted runoff would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with additional sources of polluted runoff that could result in erosion or siltation that were analyzed in the SAPP EIR. iv. Impede or redirect flood flows?
The SAPP EIR concluded that new development under the approved project would not impede or redirect flood flows and impacts would be less than significant.
According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map, the project site is not located within a floodway or floodplain. The project site is located within Zone X, defined as an area of minimal flood hazard, and outside of the FEMA 100-year floodplain (FEMA 2020). Development associated with the proposed project would not occur in an area subject to flooding. Therefore, the proposed project would not impede or redirect flood flows, and impacts would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with impeding or redirecting flood flows that were analyzed in the SAPP EIR. d. In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
The SAPP EIR identified that new development under the approved project could be placed in flood zones; however, compliance with existing programs and regulations would reduce impacts to a less- than-significant level. Therefore, the SAPP EIR concluded that impacts associated with risk release of pollutants due to project inundation would be less than significant.
As noted above, according to the FEMA Flood Insurance Rate Map, the project site is not located within a floodway or floodplain. The project site is located within Zone X, an area of minimal flood hazard (FEMA 2020). The proposed project is located approximately 2 miles southwest of Shoreline Lake and approximately 17 miles from the coast; therefore, the SAPP area would not be inundated by a seiche or a tsunami. Therefore, impacts associated with the release of pollutants due to project inundation would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts associated with the release of pollutants due to project inundation that were analyzed in the SAPP EIR.

e. Conflict with or obstruct implementation of a water quality control plan or s ustainable groundwater management plan?
The Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) water quality management plan would apply to the proposed project. The Groundwater Management Plan for the Santa Clara and Llagas Subbasins, which describes Valley Water’s groundwater sustainability goals and the strategies, programs, and activities that support those goals, would also be applicable. As discussed above, the proposed project would be covered under the existing San Francisco Bay Region Municipal Regional Stormwater NPDES permits, which would require the proposed project to implement site design measures and BMPs to reduce or prevent runoff pollution, and would be consistent with the SCVURPPP. The proposed project would comply with the SWPPP and associated construction BMPs to protect water quality. Implementation of water quality control measures and BMPs identified in the SAPP would ensure that water quality standards would be achieved, including the water quality objectives that protect designated beneficial uses of surface and groundwater, as defined in the Basin Plan. Biofiltration BMPs and planter boxes would treat runoff and allow for groundwater infiltration and recharge. Furthermore, compliance with General Plan policies including INC 8.2 (National Pollutant Discharge Elimination System Permit), INC 8.4 (Runoff pollution prevention), INC 8.5 (Site-specific stormwater treatment), and INC 8.7 (Stormwater quality) and actions and applicable COAs including COA FEP-05 (Construction Sediment and Erosion Control Plan) and COA FEP-22 (Stormwater Treatment [C.3]) would reduce this impact to a less- than-significant level. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts related to conflicts with or obstructing implementation of the applicable water quality management plans for the region that were analyzed in the SAPP EIR.

3.8 Land Use and Planning
a. Would the project physically divide an established community? The San Antonio Precise Plan (SAPP) EIR found that impacts related to the division of an established community would be less than significant. The physical division of an established community typically refers to the construction of a physical feature, such as a highway or railroad tracks, or removal of a means of access, such as a bridge, that would impair mobility within an existing community or between communities.
The project proposes demolition of two single-story commercial buildings as well as associated surface parking, and construction of a commercial building with open spaces and a below-grade parking garage. Although a building would be constructed in place of the existing two buildings and surface parking, pedestrians and commuters would still be able to navigate around the project site using existing roads and new sidewalks proposed as part of the project. Implementation of the proposed project would not impede movement within the project site and surrounding area.
Therefore, the proposed project’s impacts associated with the physical division of an established community would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the division of an established community that were analyzed in the SAPP EIR. b. Would the project cause a significant 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?
The SAPP EIR found that impacts related to conflicts with applicable land use plans, policies, or regulations would be less than significant. Potential incompatibility or conflicts with land use plans or regulations may arise from placing a particular development or land use at an inappropriate location or as a direct result from a project’s design or scope.
The City of Mountain View 2030 General Plan designates the project site as a Mixed-Use Center, which allows for a mix of pedestrian-oriented uses as well as integrated and complementary uses, such as residential, office, or retail uses, to draw visitors from surrounding neighborhoods and the Attachment 1

region. Permitted uses for the project site include offices, retail and personal services, multi-family residences, lodging facilities, entertainment venues, parks, and plazas. The project site is also within the Mixed-Use Center Subarea and the Northwest San Antonio Master Plan Area of the SAPP.
The project site is currently zoned P-40 (San Antonio Precise Plan), which is designed to provide uses or combinations of uses that may be appropriately developed as part of the SAPP area development. Furthermore, the zoning designation allows for a mix of uses, including office, commercial, retail, and residential uses. The existing commercial uses on site are consistent with the existing City of Mountain View 2030 General Plan land use designation and zoning for the project site.
As described in Chapter 2, Project Description, included in the SAPP is an office development cap to prioritize residential development and balance office development with future housing growth. The SAPP currently stipulates an area-wide maximum of 600,000 square feet of net new office development with up to 400,000 square feet permitted in the Northwest San Antonio Center Master Plan Area. Office development beyond this 400,000 square foot cap will require an amendment to the SAPP. In addition, under the SAPP, the Mixed-Use Center Subarea allows development with a floor area ratio of up to 2.35, of which 0.75 can be office or commercial uses.
The project proposes the construction of a seven-story commercial building with retail and commercial/office space, which, upon completion, would include approximately 12,970 gross square feet of retail space and approximately 169,382 gross square feet of commercial/office space, thereby exceeding the office development cap when accounting for the existing office development in the Northwest San Antonio Center Master Plan Area.
To implement the project, the project applicant proposes an amendment to the SAPP and minor amendments to the SAPP Master Plan for Area 2 to modify the office development cap in the Northwest San Antonio Master Plan area to allow additional office development through the Transfer of Development Rights (TDR) for Public Schools and update the regulations governing TDR for Public Schools Specifically, the proposed amendment would increase the 400,000-gross-square- foot limit on net new office development within the Northwest San Antonio Master Plan, while maintaining the existing 600,000 gross square feet office development limit in the SAPP The Mountain View City Council authorized the project site as a receiving site under the City of Mountain View’s TDR program with the Los Altos School District. Per the authorization, the project applicant would seek a TDR agreement to identify the project site as a receiving site under the City’s TDR program allowing the 150,000-gross-square-foot transfer from the Los Altos School District to be exempt from floor area ratio calculations.
Although the proposed project would exceed the allowable floor area ratio (2.35) and the office development cap with approval of the proposed Precise Plan amendments and TDR agreement, the project would be consistent with the existing land use and zoning designations, and would be required to adhere to the design guidelines and development standards in the SAPP, which include regulations on features such as design, signage, lighting, and landscaping requirements. Therefore, the proposed project’s impacts associated with conflicts with any land use plan, policy, or regulation would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding conflicts with any adopted land use plan, policy, or regulation, that were analyzed in the SAPP EIR.

3.9 Noise
Overview of Noise and Sound
Noise is commonly defined as unwanted sound that annoys or disturbs people and potentially causes an adverse psychological or physiological effect on human health. Because noise is an environmental pollutant that can interfere with human activities, an evaluation of noise is necessary when considering the environmental impacts of a proposed project.
Sound is characterized by various parameters, including the rate of oscillation of sound waves (frequency), the speed of propagation, and the pressure level or energy content (amplitude). In particular, the sound pressure level is the most common descriptor used to characterize the loudness of an ambient (existing) sound level. Although the decibel (dB) scale, a logarithmic scale, is used to quantify sound intensity, it does not accurately describe how sound intensity is perceived by human hearing. The human ear is not equally sensitive to all frequencies over the entire spectrum; therefore, noise measurements are weighted more heavily toward frequencies to which humans are sensitive through a process referred to as A-weighting. Table 3.9-1 summarizes typical A-weighted sound levels for different noise sources.
The effects of noise on people generally fit within three categories:
l Subjective effects of annoyance, nuisance
l Interference with activities such as speech, sleep, and learning l Physiological effects such as hearing loss

dBA = A-weighted decibel
Environmental noise typically produces effects in the first two categories. Workers in industrial plants generally experience noise in the last category. There is no completely satisfactory way to measure the subjective effects of noise or the corresponding reactions of annoyance and dissatisfaction. A wide variation exists in the individual thresholds of annoyance, and different tolerances to noise tend to develop based on an individual’s past experiences with noise. Therefore, an important way of predicting a human reaction to a new noise environment is the way it compares to the existing environment to which one has adapted, the so-called “ambient noise” level. In general, the more a new noise exceeds the previously existing ambient noise level, the less acceptable the new noise will be judged by those hearing it. Human sound perception, in general, is such that a change in sound level of 1 dB cannot typically be perceived by the human ear, a change in sound level of 3 dB is just noticeable, a change of 5 dB is clearly noticeable, and a change of 10 dB is Attachment 1
City of Mountain View
Section 3.9, Noise
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.9-3 February 2022 ICF 104340.0.001.01
perceived as doubling or halving the sound level. A doubling of actual sound energy is required to result in a 3 dB (i.e., barely noticeable) increase in noise; in practice, for example, this means that the volume of traffic on a roadway would typically need to double to result in a noticeable increase in noise (Caltrans 2013). To summarize:
l Except in carefully controlled laboratory experiments, a change of 1 dB cannot generally be perceived.
l Outside the laboratory, a 3-dB change is considered just perceivable or barely noticeable. l A change in level of at least 5 dB is required before any noticeable change in human response would be expected.
l A 10-dB change is subjectively heard as approximately a doubling in loudness and can cause an adverse response.
These relationships occur in part because of the logarithmic nature of sound and the decibel system.
The human ear perceives sound in a nonlinear fashion, which is the reason the decibel scale was developed. Because the decibel scale is based on logarithms, two noise sources do not combine in a simple additive fashion but, instead, combine logarithmically. For example, if two identical noise sources produce noise levels of 50 A-weighted decibels (dBA), the combined sound level would be 53 dBA, not 100 dBA.
If the difference between two noise sources is 10 dBA or more, the higher noise source will dominate, and the resultant noise level will be equal to the noise level of the higher noise source. In general, if the difference between two noise sources is 0 to 1 dBA, the resultant noise level will be 3 dBA higher than the higher noise source, or both sources if the sources are equal. If the difference between two noise sources is 2 to 3 dBA, the resultant noise level will be 2 dBA above the higher noise source. If the difference between two noise sources is 4 to 10 dBA, the resultant noise level will be 1 dBA higher than the higher noise source. Specifically, when adding sound levels, the relationships presented in Table 3.9-2 may be used to approximate combined overall sound levels.
Table 3.9-2. Rules for Combining Sound Levels by Decibel Addition When two decibel values differ by…
…add the following amount
to the higher decibel value Example
0 to 1 dB 3 dB 60 dB + 61 dB = 64 dB
2 to 3 dB 2 dB 60 dB + 63 dB = 65 dB
4 to 9 dB 1 dB 60 dB + 69 dB = 70 dB
10 dB or more 0 dB 60 dB + 75 dB = 75 dB
Source: Caltrans 2013.
The decibel level of a sound decreases (or attenuates) exponentially as the distance from the source of that sound increases. Sound that travels over an acoustically absorptive surface, such as grass, attenuates at a greater rate than sound that travels over a hard surface, such as pavement. The increased attenuation is typically in the range of 1 to 2 dB per doubling of distance. For a point source, such as a stationary compressor or construction equipment, sound typically attenuates at a rate of 6 dB to 7.5 dB per doubling of distance, depending on the intervening surface (e.g. vegetative surface or concrete).

Section 3.9, Noise
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.9-4 February 2022 ICF 104340.0.001.01
For a line source, such as free-flowing traffic on a freeway, sound typically attenuates at a rate of 3 dB to 4.5 dB per doubling of distance, depending on the intervening surface. Atmospheric conditions, including wind, temperature gradients, and humidity, can change how sound propagates over distance and affect the level of sound received at a given location. The degree to which the ground surface absorbs acoustical energy also affects sound propagation. Barriers, such as buildings and topography, which block the line of sight between a source and receiver, also increase the attenuation of sound over distance.
Solid walls, buildings, and berms can result in noise attenuation in the form of shielding if the line of sight between the source and receiver is blocked. Trees and foliage do to not generally result in perceptible reductions in noise levels unless the foliage is sufficiently dense to completely block the view along the propagation path (FHWA 2019). In general, if foliage is less than 10 meters in width, no attenuation occurs. If the foliage is close to 20 meters in thickness and the complete line of sight is blocked between the source and the receiver, attenuation of approximately 1 dB or less would be expected to occur (FHWA 2019).
Community noise environments are generally perceived as quiet when the 24-hour average noise level is below 45 dBA, moderate in the 45 to 60 dBA range, and loud above 60 dBA. Very noisy urban residential areas are around 70 dBA day-night level (L
dn) or the Community Noise Equivalent Level
(CNEL). Along major thoroughfares, roadside noise levels are typically between 65 and 75 dBA Ldn or CNEL. Incremental increases of 3 to 5 dB to the existing 1-hour equivalent sound level (Leq) or the Ldn/CNEL are common thresholds for an adverse community reaction to a noise increase. However, there is evidence that incremental thresholds in this range may not be sufficiently protective in areas where noise-sensitive uses are located and the L
dn or CNEL is already high (i.e., above 60 dBA).
In these areas, limiting noise increases to 3 dB or less is recommended (FTA 2006). Noise intrusions that cause short-term interior noise levels to rise above 45 dBA at night can disrupt sleep. Exposure to noise levels greater than 85 dBA for 8 continuous hours or longer can cause permanent hearing damage.
Overview of Groundborne Vibration
The operation of heavy construction equipment, particularly pile-driving equipment and other impact devices (e.g., pavement breakers), creates seismic waves that radiate along the surface of the ground and downward. These surface waves can be felt as ground vibration. Vibration from the operation of this type of equipment can result in effects that range from annoyance for people to damage for structures.
Perceptible groundborne vibration is generally limited to areas within a few hundred feet of construction activities. As seismic waves travel outward from a vibration source, they cause rock and soil particles to oscillate. The actual distance that these particles move is usually only a few ten-thousandths to a few thousandths of an inch. The rate or velocity (in inches per second) at which these particles move is referred to as peak particle velocity (PPV), the commonly accepted descriptor of vibration amplitude.
Vibration amplitude attenuates (or decreases) over distance. This attenuation is a complex function of how energy is imparted into the ground as well as the soil or rock conditions through which the vibration is traveling (variations in geology can result in different vibration levels).

The following equation is used to estimate the vibration level at a given distance for typical soil conditions (FTA 2006). PPVref is the reference PPV at 25 feet:
PPV = PPVref x (25/distance)1.5
Table 3.9-3 summarizes typical vibration levels generated by construction equipment at a reference distance of 25 feet as well as other distances, as determined with use of the attenuation equation above.

Terminology
A brief summary of the noise and vibration concepts and terminology used in this assessment is provided below.
l Sound. A vibratory disturbance transmitted by pressure waves through a medium such as air or water that is capable of being detected by a receiving mechanism such as the human ear or a microphone.
l Noise. Sound that is loud, unpleasant, unexpected, or otherwise undesirable. l Decibel (dB). A unitless measure of sound on a logarithmic scale that indicates the squared ratio of the sound pressure amplitude to a reference sound pressure amplitude. The reference pressure is 20 micropascals. Because the decibel scale is based on logarithms, two noise sources do not combine in a simple additive fashion; rather, they combine logarithmically. For instance, if two identical noise sources each produce noise levels of 50 dBA (see definition immediately following), the combined sound level would be 53 dBA, not 100 dBA. l A-Weighted Decibel (dBA). An overall frequency-weighted sound level in decibels that approximates the frequency response of the human ear. The dBA scale is the most widely used for environmental noise assessments.
l Maximum Sound Levels (Lmax). The maximum sound level measured during a given measurement period.
l Minimum Sound Levels (Lmin). The minimum sound level measured during a given measurement period.
l Equivalent Sound Level (Leq). The equivalent steady-state sound level that, in a stated period of time, would contain the same acoustical energy. The 1-hour A-weighted equivalent sound level (Leq 1h) is the energy average of A-weighted sound levels occurring during a 1-hour period. l Day-Night Level (Ldn). The energy average of the A-weighted sound levels occurring during a 24-hour period, with a 10-dB penalty added to sound levels between 10:00 p.m. and 7:00 a.m. l Community Noise Equivalent Level (CNEL). The energy average of the A-weighted sound levels occurring during a 24-hour period, with 5 dB added to the sound levels occurring during the period from 7:00 p.m. to 10:00 p.m. and 10 dB added to the sound levels occurring during the period from 10:00 p.m. to 7:00 a.m. L
dn and CNEL are typically within 1 dBA of each other
and, for all intents and purposes, interchangeable.
l Vibration Velocity Level (or Vibration Decibel Level, VdB). The root-mean-square velocity amplitude for measured ground motion, expressed in dB.
l Peak Particle Velocity (PPV). A measurement of ground vibration, defined as the maximum speed at which a particle in the ground is moving, expressed in inches per second (in/sec). l Noise-Sensitive Land Uses. Noise-sensitive land uses are generally defined as locations where people reside or the presence of unwanted sound could adversely affect use of the land. Noise- sensitive land uses typically include single- and multi-family residential areas, health care facilities, lodging facilities, and schools. Recreational areas where quiet is an important part of the environment can also be considered sensitive to noise. Some commercial areas may be considered noise sensitive as well, such as outdoor restaurant seating areas.

Existing Noise-Sensitive Uses in the Vicinity
The nearest noise-sensitive land uses to the project site are the residences at 2580 and 2590 California Street, which are currently under construction. It is anticipated that construction will be complete for these buildings and that these residences will be occupied during construction and operation of the proposed project. 2580 California Street is approximately 100 feet north of the project site, and 2590 California Street is approximately 200 feet northeast of the project site.
Additional residential land uses are farther to the east (to the east of 2590 California Street). These single-family residences, the nearest of which is 163 Pachetti Way, are more than 530 feet east of the project site. Additional multi-family residential land uses are to the southwest of the project site (at 400 San Antonio Road) at distances of approximately 220 feet and more from the project property line. In addition, there are two hotels in the general vicinity of the project site: the Hyatt Centric Mountain View is approximately 350 feet southeast of the project site, and the Residences at San Antonio is approximately 710 feet southeast of the project site. There are also two schools near the project site. The closest of the two is the Community School of Music and Arts at 230 San Antonio Circle, at a distance of 580 feet northwest of the project site.
Applicable Noise Regulations and Policies
As explained in the noise setting in the San Antonio Precise Plan (SAPP) EIR, the noise standards and policies most applicable to the types of noise sources associated with construction and operation of the project are found in the City of Mountain View 2030 General Plan (General Plan), the City of Mountain View (City) Municipal Code, and the City’s Standard Conditions of Approval (COAs), which are presented in greater detail below.
City of Mountain View 2030 General Plan Noise Element
The General Plan noise acceptability guidelines indicate that outdoor noise levels below 67.5 dBA L
dn for office buildings and business commercial and 60 dBA Ldn for hotels are normally acceptable.
The Noise Element policies that relate to the project are listed below.
Policy NOI 1.1: Land Use Compatibility. Use the Outdoor Noise Acceptability Guidelines as a guide for planning and development decisions.
Policy NOI 1.3: Exceeding Acceptable Noise Thresholds. If noise levels in the area of a proposed project would exceed normally acceptable thresholds, the City shall require a detailed analysis of proposed noise reduction requirements to determine whether the proposed use is compatible. As needed, noise insulation features shall be included in the design of such projects to reduce exterior noise levels to meet acceptable thresholds, or for uses with no active outdoor use areas, to ensure acceptable interior noise levels.
Policy NOI 1.4: Site Planning. Use site planning and project design strategies to achieve the noise level standards in NOI 1.1 (Land Use Compatibility) and in NOI 1.2 (Noise Sensitive Land Uses). The use of noise barriers shall be considered after all practical design-related noise measures have been integrated into the project design.
Policy NOI 1.5: Major Roadways. Reduce the noise impacts from major arterials and freeways.
Policy NOI 1.6: Sensitive Uses. Minimize noise impacts on noise-sensitive land uses, such as residential uses, schools, hospitals, and child-care facilities.
Policy NOI 1.7: Stationary Sources. Restrict noise levels from stationary sources through enforcement of the Noise Ordinance

City of Mountain View Municipal Code
The following sections of the City’s Municipal Code are applicable to noise-generating sources associated with the proposed project.
Section 8.70—Construction Noise
a. Hours of construction. No construction activity shall commence prior to 7:00 a.m. nor continue later than 6:00 p.m., Monday through Friday, nor shall any work be permitted on Saturday or Sunday or holidays unless prior written approval is granted by the chief building official. The term "construction activity" shall include any physical activity on the construction site or in the staging area, including the delivery of materials. In approving modified hours, the chief building official may specifically designate and/or limit the activities permitted during the modified hours. b. Modification. At any time before commencement of or during construction activity, the chief building official may modify the permitted hours of construction upon twenty-four (24) hours written notice to the contractor, applicant, developer or owner. The chief building official can reduce the hours of construction activity below the 7:00 a.m. to 6:00 p.m. time frame or increase the allowable hours.
c. Sign required. The general contractor, applicant, developer or owner shall erect a sign at a prominent location on the construction site to advise subcontractors and material suppliers of the working hours. The sign shall include: address number (minimum twenty-four (24) inches by thirty- six (36) inches in contrasting colors), contact name and number, construction hours, contractor info (as stated on your job card). Any modification of standard hours will require additional signage. The contractor, owner or applicant shall immediately produce upon request any written order or permit from the chief building official pursuant to this section upon the request of any member of the public, the police or city staff.
d. Violation. Violation of the allowed hours of construction activity can result in a stop work notice and/or a reduction of regular construction hours for the duration of the project. Required signage shall be posted or the site shall be considered in violation of this section of the Code under the direction of the chief building official's order.
Section 21.26—Stationary Equipment Noise
a. No person shall own or operate on any property any stationary equipment, such as, but not limited to, air compressors, equipment for swimming pools, spas, or air conditioners, which produces a sound level exceeding 55 decibels (dB) (50 dB during the night, 10:00 p.m. to 7:00 a.m.) when measured at any location on any receiving residentially used property, said measurement to utilize a sound level meter equal to or better than an ANSI Standard S 1.4-1971 Type 2 noise level meter. b. Any plans submitted for building, plumbing, electrical or mechanical/heating permit for any stationary equipment shall be accompanied by documentation of the equipment noise level when available and by noise mitigating devices or buffers appropriate to achieve the above noise limit.
Initial granting of a permit for such equipment shall not affect the obligation of each person owning or operating such equipment for continued compliance with these noise level requirements. c. Operation of any equipment, as specified in this section, above the 55 dB limit (50 dB nighttime), may occur only if the owner or operator has obtained a conditional use permit.

Impact Discussion
a. Would the project generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Construction of the project would involve multiple noise-generating activities, including demolition of the existing buildings and surface parking lot and use of heavy construction equipment. Noise- generating sources associated with operation of the project would include the occasional testing of a backup emergency generator; a heating, ventilating, and air conditioning (HVAC) system; truck activity in the loading areas; and increased traffic on area roadways. These noise sources are discussed separately below along with any of the City’s Standard COAs applicable to each noise source.
Temporary Construction Activity
Federal Highway Administration (FHWA) Roadway Construction Noise Model calculation methods were used to estimate reasonable worst-case combined noise. Noise from the loudest three pieces of equipment proposed for use during a single construction phase was calculated. This project would involve six construction phases: demolition, excavation/shoring/grading, foundation, structure building/exterior systems, site improvements, and final closeout. The nearest noise-sensitive receivers to project construction areas are the apartments currently under construction at 2580 California Street (approximately 100 feet north of the project site). These residences are expected to be occupied during project construction.
During project demolition, the three loudest pieces of equipment proposed for use are two Cat 330 Excavators and a street sweeper. Estimated worst-case noise levels would be 75 dBA Leq at the nearest sensitive receiver. During the excavation, shoring, and grading phase, drilling would occur.
Specifically, it is expected that the three loudest pieces of equipment would be three types of auger drill rigs: a Cammachio MC20, a Lo-Ho Drill DH40, and a Delmag RH26. Based on modeling of combined noise levels during this phase, construction noise level from this phase may be as high as 76 dBA L
eq at the nearest sensitive receiver. During the foundation phase, the three loudest pieces of equipment expected to operate simultaneously are a concrete pump, a gradall, and a forklift. Noise levels during this phase could be high as 77 dBA Leq at the nearest sensitive receiver.
During the structure building and exterior systems phase, the three loudest pieces of equipment proposed for use are two gradalls and a forklift. At the nearest sensitive receptor, noise levels may be as high as 78 dBA Leq. During the site improvements construction phase, a backhoe and soil compactor may be used, resulting in estimated combined noise levels of up to 72 dBA Leq. In addition, the loudest pieces of equipment proposed for the final closeout phase are two gradalls and a boom lift, which would result in estimated combined noise levels at the nearest sensitive receiver of up to 76 dBA L
eq.
In summary, noise generated by project construction could be up to 78 dBA Leq at the nearest sensitive receiver (e.g., during the structure building and exterior systems phase). Refer to Table
3.9-6 for estimated combined noise from equipment proposed from this phase at various distances.
Refer to Appendix C for the construction noise modeling results for all construction phases.

Bold denotes distance and sound levels from the project site to the nearest sensitive receiver.
Note that construction may also involve the use of haul trucks, with up to 80 trucks per day estimated to access the site. Although hauling activity would occur mostly along relatively busy roadways in the project area, hauling activity may result in temporary perceptible increases in noise at sensitive land uses. Therefore, project construction and hauling activities may both result in temporary increases in noise in the general project vicinity during daytime hours.
Although construction activity would result in elevated noise levels at nearby land uses, construction noise would be temporary, intermittent, and periodic and would primarily occur during daytime hours when people are less sensitive to noise. Also, COA PL-152 requires construction contractors to implement measures to minimize the exposure of offsite receptors to noise generated by construction equipment. In addition, COA PL-188 requires the project applicant to give advance notice of construction activity to neighbors within 750 feet of the project site and COA PL-189 requires the applicant to establish a disturbance coordinator to address any concerns about construction noise and implement reasonable measures to limit noise exposure. Moreover, because construction activity would only occur between 7:00 a.m. and 6:00 p.m. on weekdays, as required by both COA PL-186 and Section 8.70 of the City’s Municipal Code, construction noise would be generated only during daytime hours when people are less sensitive to noise. Because Attachment 1

daytime construction would be temporary, would involve implementation of all applicable COAs, and would comply with the time-of-day restrictions specified in the City’s Municipal Code, construction noise would comply with the applicable local regulations. Therefore, the proposed project’s impacts associated with construction noise levels in excess of local standards would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding construction noise levels in excess of local standards that were analyzed in the SAPP EIR.
HVAC Equipment Operation
The SAPP EIR explains that all stationary sources of noise on land uses developed under the SAPP would be required to comply with the daytime and nighttime noise standards established in Section
21.26 of the City’s Municipal Code. This is stated in General Plan Policy NOI 1.7 and is also required by COA PL-149. Therefore, noise impacts from stationary noise sources were not evaluated extensively in the SAPP EIR and were assumed to be less than significant.
Noise-generating mechanical equipment at the project site would include HVAC equipment on the rooftop of the building and limited equipment on the exterior of the building at ground level.
Although the exact make and model of the HVAC equipment have not been determined at the time of writing this document, a typical HVAC unit, which includes condensing units and fans, produces sound levels in the range of 70 to 75 dB at 50 feet (Hoover & Keith, Inc. 2000). These units will be placed on the roof, which sits 95 feet above the ground. Assuming no intervening buildings, barriers, or topography, The higher end of this estimated noise range, 75 dB at 50 feet, would attenuate to the City’s daytime noise standard of 55 dB at a distance of 475 feet, and to the City’s nighttime standard of 50 dB at a distance of 850 feet,. Therefore, without implementation of noise reduction measures, there would be the potential for noise generated by HVAC equipment at the project site to expose nearby residences to noise levels in excess of thresholds. Specifically, the new mixed-use development 100 feet north of the project site at 2580 and 2590 California Street, as well as the residential land use 220 feet southwest of the project site at 400 San Antonio Street, could be exposed to noise levels that exceed the daytime and nighttime noise standards established in Section 21.26 of the City’s Municipal Code before accounting for noise attenuation. There would also be the potential for unattenuated noise generated by HVAC equipment to expose residents at sensitive uses farther from these distances to noise levels in excess of the applicable criteria.
However, the mechanical roof top equipment will be located behind a mechanical screen, which would help reduce noise somewhat, and the limited equipment at the ground level will be placed on Silicon Way, interior to the project site and away from sensitive receptors.
Although unattenuated HVAC noise based on the modeling assumptions above may result in noise levels in excess of limits, the project’s HVAC system would be required to comply with COA PL-149 (Mechanical Equipment), which requires that noise emitted by any mechanical equipment not exceed a level of 55 dB during the day (7:00 a.m. to 10:00 p.m.) or 50 dB during the night (10:00 p.m. to 7:00 a.m.) when measured at any location on a residential property. Therefore, the building’s HVAC equipment would be required to include design features such as enclosures or shielding around noise-generating equipment. Furthermore, relatively quiet HVAC models or mufflers or silencers on exhaust fans would be required to ensure compliance with COA PL-149.
Implementation of these measures would be expected to reduce HVAC equipment noise to below the applicable standards. Adherence to COA PL-149 would ensure that noise from project HVAC equipment would not exceed the applicable thresholds at residential land uses. Therefore, the proposed project’s impacts associated with HVAC equipment operation noise levels in excess of local Attachment 1
City of Mountain View
Section 3.9, Noise
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.9-13 February 2022 ICF 104340.0.001.01
standards would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding HVAC equipment operation noise levels in excess of local standards that were analyzed in the SAPP EIR.
Testing of the Emergency Backup Generator
The project would also include an emergency backup generator. Noise from the use of backup generators is generally considered exempt when used during an emergency. However, the project emergency backup generator would be operated occasionally for testing and maintenance. While the size, make, and model of the generator are not known at the time of writing this document, it is expected that the project generator would have a 500-kilowatt capacity. As an example, a Cummins Model QSX15 500-kilowatt generator can generate an estimated noise level of 89 dB at a reference distance of 7 meters (Cummins, Inc. 2015), which is equivalent to 82 dB at 50 feet.
As is the case for the project’s HVAC equipment, the backup generator would be required to comply with COA PL-149 (Mechanical Equipment), which requires that noise emitted by any mechanical equipment not exceed a level of 55 dB during the day (7:00 a.m. to 10:00 p.m.) or 50 dB during the night (10:00 p.m. to 7:00 a.m.) when measured at any location on a residential property. The proposed backup generator would be located within a ground floor room interior to the building, which would somewhat reduce noise, especially from the engine of the generator. Note that generator noise is made of both engine noise and exhaust noise, and the diesel exhaust is typically piped or exhausted to the external of the building. Therefore, because exhaust noise may not be substantially reduced, enclosing the generator in an interior room may not reduce noise from the generator to below significance criteria. Compliance with COA PL-149 (Mechanical Equipment), however, would ensure that overall noise levels from generator testing would be reduced to below the applicable significance criteria of 55 dB during the day (7:00 a.m. to 10:00 p.m.) and 50 dB during the night (10:00 p.m. to 7:00 a.m. Therefore, the proposed project’s impacts associated with noise levels in excess of local standards would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding noise levels in excess of local standards that were analyzed in the SAPP EIR. .
Truck Loading/Unloading Activity
Once operational, it is expected that up to five daily deliveries to the project site, in the form of medium and or heavy trucks, could occur. Although loading activity generates noise, the loading and unloading of goods is a common occurrence in urban environments. In addition, project loading activities would occur predominantly during daytime hours when people are less sensitive to noise.
Furthermore, the project loading dock is proposed to be on the southern perimeter of the project site, approximately 100 feet east of San Antonio Road. Therefore, loading activities would be shielded from the residences north of the project site. In addition, the line of sight between the residences at 400 San Antonio Road would be largely blocked by intervening buildings. Thus, intermittent noise from loading and unloading activities (e.g., an estimated five per day, spread out over a given day) at the project site would not be expected to result in a substantial increase in the ambient noise levels in the project area. Therefore, the proposed project’s impacts associated loading activity noise on nearby noise sensitive land uses would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding loading activity noise on nearby noise sensitive land uses that were analyzed in the SAPP EIR.

Traffic Noise
Because the project includes development of a specific commercial building, a project-level analysis of traffic noise is provided here to determine whether vehicle trips associated with the project would result in traffic noise impacts.
Once operational, the project would lead to an increase in traffic in the vicinity of the project site, as detailed in Section 3.13. Project-specific traffic data, including average daily traffic volumes, were provided by Fehr & Peers (see Appendix D). Modeling was conducted for existing and existing plus- project conditions to estimate traffic noise increases resulting from project implementation along roadway segments in the project vicinity.
When assessing traffic noise impacts, the following thresholds are applied to determine the significance of project-related traffic noise increases:
1. An increase of more than 5 dBA is considered a significant traffic noise increase, regardless of the existing ambient noise level.
2. In places where the existing or resulting noise environment is “conditionally acceptable,” “normally unacceptable,” or “clearly unacceptable,” based on the City Land Use Compatibility Guidelines, any noise increase greater than 3 dBA is considered a significant traffic noise increase.
According to the General Plan Noise Element, a noise level of up to 60 dBA L dn is considered
normally acceptable for multi-family residential land uses, and 55 dBA Ldn is considered normally acceptable for single-family residential land uses.
As previously discussed, a 10-percent increase in traffic equates to less than a 1-dB (approximately
0.4 dB) increase in noise. A change in sound level of 1 dB is not typically perceived by the human ear and is below the substantial increase criteria for traffic noise impacts. Therefore, roadway segments with less than a 10-percent change would not experience a substantial increase in noise (either a 3- or 5-dB increase, depending on existing noise levels) or significant traffic noise impacts. Because no roadway segments analyzed in the traffic analysis would experience a 10-percent or more increase in traffic with project implementation, only roadway segments relatively close to the project site were quantitatively modeled.
Traffic noise modeling was conducted using a spreadsheet based on the FHWA Traffic Noise Model, version 2.5. This spreadsheet calculates the traffic noise level at a fixed distance from the centerline of a roadway, based on the traffic volume, roadway speed, and vehicle mix predicted to occur under each condition. Traffic noise was evaluated in terms of how project-related traffic noise increases could affect existing noise-sensitive land uses as well as proposed onsite sensitive land uses in the project area. Refer to Table 3.9-7 for the traffic noise modeling results.
As shown in Table 3.9-5, modeling demonstrated that noise levels along the adjacent segments would increase by a maximum of 0.2 dB as a result of project implementation. As described previously, a 3-dB increase is considered barely noticeable and would not constitute a significant increase in noise. An increase of 0.2 dB would not be considered substantial. Therefore, the proposed project’s impacts associated with traffic noise on off-site noise sensitive land uses would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding traffic noise on off-site noise sensitive land uses that were analyzed in the SAPP EIR. .

b. Would the project generate excessive groundborne vibration or groundborne noise levels? Project-related demolition and construction would involve the use of heavy equipment that generates ground vibration. The most vibration-intensive equipment proposed for use during project construction are a pile driver and an auger drill. These and other types of heavy equipment create seismic waves that radiate along the surface of the ground and downward. These surface waves can be felt as ground vibration. Vibration from the operation of this type of equipment can result in effects that include damage to structures and annoyance to people.
Vibration amplitudes are commonly expressed two different ways: PPV and root-mean-square vibration velocity. PPV and root-mean-square vibration velocity are normally described in in/sec or in millimeters per second. PPV is defined as the maximum instantaneous positive or negative peak of a vibration signal. PPV is typically used in the monitoring of transient and impact vibration and has been found to correlate well to the stresses experienced by buildings (FTA 2018; Caltrans 2020).
Vibration amplitude attenuates (or decreases) over distance. This attenuation is a complex function of how energy is imparted into the ground as well as the soil or rock conditions through which the vibration is traveling (variations in geology can result in different vibration levels).
With regard to vibration-related annoyance, a significant vibration impact related to sleep disturbance could occur when nighttime construction activities generate vibration levels that are strongly perceptible (i.e., PPV of 0.1 in/sec) (as shown in Table 3.9-4) at locations where people typically sleep. Sleep disturbances from vibration typically occur only if residences are very close to nighttime ground-disturbing construction activities. The nearest residential land uses would be approximately 100 feet north of the project site. However, COA PL-186 (which limits construction activity to the hours of 7:00 a.m. to 6:00 p.m., and enforces Section 8.70 of the City’s Municipal Code) would be implemented. Therefore, because no nighttime construction activities are proposed, project-related demolition and construction activity would not result in sleep disturbance at nearby residential land uses.

Section 3.9, Noise
Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.9-16 February 2022 ICF 104340.0.001.01
The most vibration-intensive equipment proposed for use during project construction are a large bulldozer and an auger drill, both of which have a reference vibration level of 0.089 PPV in/sec at a distance of 25 feet. This equipment could be operating as close as 100 feet from the nearest occupied residential land use during daytime hours. At a distance of 100 feet, the vibration level from an auger drill and a large bulldozer would be reduced to approximately 0.011 PPV in/sec. This is well below the strongly perceptible criterion of 0.1 PPV in/sec and the distinctly perceptible criterion of 0.04 PPV in/sec. Therefore, even during daytime hours, construction-related vibration would be unlikely to result in substantial levels of perceptible vibration. Vibration-related annoyance impacts would be less than significant.
Regarding potential vibration-related damage effects, equipment could operate as close as 25 feet from the nearest existing structure. The nearest offsite structure is the relatively new commercial office building adjacent south of the project site at 391 San Antonio Road. As shown in Table 3.9-1, the vibration level from a large bulldozer or auger drill at a distance of 25 feet would be approximately
0.089 PPV in/sec. This is below the vibration-related damage criterion for modern industrial/commercial buildings of 0.5 PPV in/sec, as shown in Table 3.9-5 (Caltrans 2020). Because project-related activities would not exceed the applicable damage criterion at nearby structures, vibration-related damage impacts would be less than significant.
The analysis under Impact NOISE-1 of the SAPP EIR determined that construction activities associated with development and redevelopment under the SAPP could result in exposure of sensitive land uses to excessive levels of ground vibration, and required implementation of Mitigation Measure NOISE-1, which pertained to notification of residents if pile driving is anticipated, phasing high-vibration generating construction activities, and avoiding other high-impact construction activities where feasible. The SAPP EIR determined that implementation of Mitigation Measure NOISE-1 would ensure that the exposure of sensitive receptors to excessive groundborne vibration levels from demolition and construction activities would be sufficiently mitigated to be less than significant.
In summary, the project-related demolition and construction activity would not result in structural damage to nearby buildings or sleep disturbance at nearby residential land uses. Moreover, development of the project would not include the long-term operation of any source of ground vibration atypical of developed urban areas. Therefore, with SAPP EIR mitigation measure applied, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with vibration would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding vibration that were analyzed in the SAPP EIR.
c. F or a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
The noise setting in the SAPP EIR explains that the SAPP area, and therefore the Plan Area of the Village at San Antonio Phase III, lies outside of the 55 dB CNEL noise contour of the Palo Alto Airport and outside the 60 dB CNEL noise contour of the Moffett Federal Airfield. The most recent comprehensive land use plans for these airports show that this remains the case (Santa Clara County 2016a, 2016b). The SAPP EIR also explains that the SAPP area is approximately 12 miles from San Jose International Airport and approximately 18 miles from San Francisco International Airport and, therefore, concludes that aircraft noise from these four nearest airports is not a substantial contributor to the existing noise environment in the plan area.

3.10 Population and Housing
a. Would the project induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
The San Antonio Precise Plan (SAPP) EIR found that impacts related to direct and indirect substantial unplanned population growth would be less than significant.
Construction
Construction of the project would result in a temporary increase in the number of construction- related job opportunities in the Plan Area and surrounding local area. However, the opportunities provided by project construction would most likely not result in construction workers relocating their households to the project vicinity because these jobs would be temporary. It is expected that construction workers would be drawn from the construction labor force already residing in Mountain View and the surrounding communities. However, the construction jobs produced by this project would be new jobs, and would slightly alter the balance of jobs to employed residents in Mountain View. This effect would not be permanent, and would not be expected to change the current ratio of 2.07 jobs per employed resident.1 Accordingly, employment opportunities provided by construction of the project would not generate substantial population growth. Therefore, the proposed project’s impacts associated with unplanned population growth during construction activities would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding unplanned population growth during construction activities that were analyzed in the SAPP EIR.
1 In 2019, the City of Mountain View had 101,965 jobs and 49,084 employed residents, a ratio of 2.08 jobs for every employed resident (U.S. Census Bureau 2020a, 2020b).

Operation
The project does not include the development of housing and therefore would not directly induce population growth. A such, the proposed project would not generate substantial direct population as a result of project operation, and the project would not result in new significant impacts or a substantial increase in the severity of impacts regarding substantial direct population that were analyzed in the SAPP EIR.
The SAPP EIR determined that there would be an increase of approximately 3,695 jobs as a result of development of commercial and service uses under the SAPP. Approximately 12 individuals are currently employed on the project site. With implementation of the project, a total of approximately 1,500 office employees would work at the project site upon completion and occupancy of the new building. This would result in a net increase in employment amounting to 1,488 employees, or approximately 40 percent of the projected employment growth under the SAPP. The number of employees associated with the project would be within the Plan Area projected growth. The net increase in 1,488 employees could potentially cause people to move to the area or surrounding communities; however, many of the new jobs would likely be occupied by those already living in the area or surrounding cities and, as a result, the increase in jobs is not likely to result in a substantial number of people moving into the Plan Area. Furthermore, as detailed in the SAPP EIR, population growth, both direct and indirect, associated with buildout of the Plan Area would not be considered substantial or adverse, based on the developed nature of Mountain View and the proximity of the Plan Area to employment centers and transit infrastructure. Population growth that would occur as a result of buildout under the SAPP would be consistent with the City of Mountain View 2030 General Plan goal of supporting transit-oriented development along transit corridors, and would primarily occur as intensification of uses and infill.
The project would require the extension of certain utilities, which could indirectly induce growth in adjacent areas. However, the proposed project is an infill project, and the project site and surrounding areas are already developed with residential, commercial, and office uses as well as associated infrastructure to serve these uses. Furthermore, the proposed project would not require the construction of any new roads. Therefore, the proposed project’s impacts associated with substantial unplanned population growth during operation activities would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding substantial unplanned population growth during operation activities that were analyzed in the SAPP EIR. b. Would the project displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? The SAPP EIR found that impacts related to displacement of substantial numbers of existing housing or people would be less than significant.
The project site is currently composed of a commercial office building, a retail building, and approximately 45 surface parking spaces. No residential uses are currently located on the project site. No housing or residents would be displaced as a result of the project. Therefore, the proposed project would have no impact associated with the displacement of a substantial number of existing people or housing. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the displacement of existing people or housing that were analyzed in the SAPP EIR.

a. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services:
i. Fire protection?
The San Antonio Precise Plan (SAPP) EIR found that impacts related to fire protection services would be less than significant.
Fire protection and emergency services to the project site and Plan Area are provided by the Mountain View Fire Department (MVFD). MVFD also participates in an automatic aid program with the cities of Sunnyvale, Palo Alto, Los Altos, and the National Aeronautics and Space Administration Ames Fire Department at Moffett Field, in addition to statewide programs and mutual aid programs.
MVFD has an established response time goal of 4 minutes (from dispatch) for “Medical Code Three” Attachment 1

calls (i.e., those requiring expedited transport). During the 2018 to 2019 fiscal year (July 1, 2018, to June 30, 2019), the most recent fiscal year for which information is available, MVFD regularly met or exceeded this goal. During 2018, MVFD had 87 personnel, including 30 paramedics. MVFD operates five fire stations, the closest of which is Station 3 at 301 North Rengstorff Avenue, approximately 1.3 miles northeast of the Plan Area.
Although the addition of 1,488 net new employees to the project site and larger Plan Area would slightly increase the need for fire protection services from MVFD, the proposed project would be constructed in an area already served by MVFD. In addition, the proposed project would be required to adhere to the City’s Standard Conditions of Approval, which require fire protection systems within all proposed buildings and throughout the entire project site, such as fire hydrants, fire extinguishers, and smoke alarms. During construction, the project would be required to adhere to Standard Condition of Approval PW-135, Miscellaneous—Construction Management Plans, which requires a construction traffic and parking management plan with the building plans, as well as FD- 05, Fire Protection During Construction, which requires the building to be connected to a temporary standpipe system during construction to which fire hoses can connect, as the proposed building would be larger than four stories. Furthermore, the project site would be designed to facilitate access for emergency vehicles, which would be able to access the project site from one location on California Street and one location on San Antonio Road. The internal project streets of Silicon Way and Promenade Lane would provide full emergency access around the project site. Response times to the project site and Plan Area would not substantially change with project implementation.
Therefore, the proposed project’s impacts associated with fire protection would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding fire protection that were analyzed in the SAPP EIR. ii. Police protection?
The SAPP EIR found that impacts related to police protection services would be less than significant.
The Mountain View Police Department (MVPD) provides police services in Mountain View. MVPD operates out of one police station at 1000 Villa Street. MVPD has a staff of 96 sworn and 48.5 non- sworn personnel. In addition, MVPD conducts an active volunteer program, which involves approximately 14 non-sworn volunteers. Each beat is staffed by one officer, with one or two “roving” units who patrol the entire city. Multiple shifts overlap throughout a 24-hour cycle, so there could be up to three officers in one beat at any given time. MVPD separates Mountain View into four beats; the project site and Plan Area are in Beat 2. According to MVPD’s 2020 Annual Report (MVPD 2020), officers were dispatched to 5,043 calls within Beat 2.
MVPD’s goal is to respond to emergency and Priority 1 calls, which warrant emergency dispatch and are the highest priority, in less than 4 minutes at least 55.5 percent of the time. In 2020, response time to emergency and Priority 1 calls was 4 minutes or less 62.8 percent of the time. However, MVPD’s 2020annual report found that the average citywide response time for events at all priority levels combined for Beats 1 through 4 was 14.3 minutes.
Although the addition of 1,488 net new employees to the project site and larger Plan Area would slightly increase the need for police protection services from MVPD, the proposed project would be constructed in an area already served by MVPD. In addition, the SAPP EIR notes that although development would incrementally increase demands for police protection services, planned development within the Plan Area itself would not directly result in adverse physical impacts associated with the construction of new public facilities because new officers could be housed in Attachment 1

existing police facilities, and no new construction would be required. On this basis, the SAPP EIR found that implementation of the SAPP would have a less-than-significant impact on police protection services and facilities. The project would be consistent with the land uses assumed for the site in the SAPP. Furthermore, the project would be required to adhere to Standard Conditions of Approval FD-43, Emergency Responder Radio Coverage to improve onsite security Response times to the project site and Plan Area would not substantially change with project implementation.
Therefore, the proposed project’s impacts associated with police protection would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding police protection that were analyzed in the SAPP EIR. iii. Schools?
The SAPP EIR found that impacts related to schools would be less than significant.
Mountain View is served by three public school districts: Mountain View Whisman School District, Mountain View-Los Altos Union High School District (MVLA UHSD), and Los Altos School District (LASD). The project site and Plan Area are served by elementary and middle schools in LASD and by high schools in MVLA UHSD. The LASD schools that would serve the Plan Area, including the project site, include Santa Rita, Almond, and Covington elementary schools and Egan Junior High School. Los Altos High School, part of MVLA UHSD, would also serve the Plan Area and project site. LASD has a maximum student enrollment capacity of 5,676 students across the elementary and middle schools (LASD 2020), while Los Altos High School has a maximum student enrollment capacity of 1,579. For the 2019–2020 school year, LASD was within its maximum capacity and had a total enrollment of 3,999 students. MVLA UHSD had a total enrollment of 4,548 students, with Los Altos High School currently supporting 2,253 students, resulting in approximately 674 students over the school’s capacity (Ed-Data 2021a, 2021b).
According to the SAPP EIR, LASD has a student generation rate of 0.63 elementary and middle school student per single-family detached unit and 0.3 student per multi-family residential unit, and MVLA UHSD has a student generation rate of 0.115 student per single-family detached residential unit and 0.046 student per apartment/attached residential unit. The SAPP EIR projected that 427 additional students would be generated under full implementation of the SAPP, with 57 students being added to MVLA UHSD and 370 students being added to LASD.
The project does not include the development of housing and therefore would not directly induce new student enrollment at the school districts or directly increase enrollment at the school districts beyond their current capacity. However, as described in Section 3.11, Population and Housing, the net increase in 1,488 employees could potentially cause people to move to the area or surrounding communities, thereby potentially generating a small number of new students who would attend schools within LASD or MVLA UHSD. It is likely that many of the new employees generated by the proposed project would likely be those already living in the area or surrounding cities and, as a result, the increase in employees to the project site and Plan Area is not likely to result in a substantial number of new students enrolling into the school districts. Nonetheless, as stated above, the SAPP EIR projected that 427 additional students would be generated under full implementation of the SAPP, with 57 students being added to MVLA UHSD and 370 students being added to LASD, thus exceeding MVLA UHSD’s capacity.
School districts are authorized under California Government Code Section 65996 and Education Code Section 17620 to levy a development fee on new residential and commercial projects to offset costs associated with new students in districts as a result of new development. The project would be Attachment 1

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.11-4 February 2022 ICF 104340.0.001.01
required to comply with these codes under Standard Condition of Approval BID-44 (School Impact Fee). Section 65996 states that the payment of school impact fees, as required by a state or local agency, is deemed full and complete mitigation for school impacts from development. The project would pay the applicable development impact fee, which could be used to help offset the cost of expanding or constructing new school facilities and hiring new personnel, including teachers. It is not expected that the proposed project would generate students such that new facilities would be required. Therefore, the proposed project’s impacts associated with schools would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding schools that were analyzed in the SAPP EIR. iv. Parks?
The SAPP EIR found that impacts related to parks would be less than significant. Refer to impact b and impact c below for a discussion of the proposed project’s impacts on parks and recreational resources.
v. Other public facilities?
The SAPP EIR found that impacts related to community or public facilities would be less than significant.
There is one library in Mountain View, the Mountain View Public Library at 585 Franklin Street. The library was remodeled and expanded in 2018 to meet the needs of Mountain View’s growing population. The library provides reference and reader assistance, library programming, internet access, and print and media materials.
The project does not include the development of housing and, therefore, would not directly result in impacts on public facilities, such as the library. However, as described in Section 3.11, Population and Housing, the net increase in approximately 1,500 employees could potentially cause people to move to the area or surrounding communities, thereby potentially generating a small number of people who may utilize community or public facilities, including the library. It is likely that many of the new employees generated by the proposed project would be those already living in the area or surrounding cities and, as a result, the increase in employees to the project site and Plan Area is not likely to result in a substantial number of new people utilizing the library, and the library would continue to provide adequate service to the project site, Plan Area, and city at large. In addition, the SAPP EIR determined that population and employment growth associated with buildout and implementation of the SAPP, which accounts for the proposed project, would not result in significant impacts on community facilities. It is not expected that the proposed project would generate a substantial number of new users such that new library or other community facilities would be required. Therefore, the proposed project’s impacts associated with other public facilities would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding other public facilities that were analyzed in the SAPP EIR. b. Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?
The SAPP EIR found that impacts related to increased use of existing neighborhood and regional parks or other recreational facilities resulting in substantial physical deterioration of the facility would be less than significant.

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.11-5 February 2022 ICF 104340.0.001.01
The city has nearly 1,000 acres of parks and open space as well as an interconnected system of trails that links neighborhoods to parks and other community facilities, including recreational facilities.
The city had 13.5 acres of parkland per 1,000 residents in 2011, substantially better than the City standard of 3 acres per 1,000 residents. Two large regional open spaces, Shoreline at Mountain View Regional Park within the North Bayshore Planning Area, and Stevens Creek Trail, account for 80 percent of Mountain View’s park and open space area.
There are three parks within 0.5 mile of the project site:
l Del Medio Park: Del Medio Park is the closest park to the project site, approximately 0.19 mile west of the site. The approximately 0.38-acre mini park includes a children’s playground, swings, outdoor exercise equipment, passive areas, benches, and a picnic area. l Monroe Park: The 0.55-acre Monroe Park is approximately 0.35 mile west of the site at the Palo Alto–Mountain View border. The park includes a playground, benches, and passive areas. l Klein Park: The 1.90-acre Klein Park is approximately 0.45 mile east of the project site. The park includes a basketball court, children’s playground, passive areas, and a picnic area.
It is possible that some of the proposed project’s employees may use parks, open space, and recreational facilities during lunch or after work, thereby generating a small, indirect increase in park use. However, because the proposed project would not involve the construction of any housing units, it is not anticipated that the proposed project would generate a substantial increase in demand for recreational and park facilities. In addition, with implementation of the project, private and public open space would be provided throughout the site. The streetscape would consist of at- grade and raised planters with built-in seating. Benches, bicycle racks, and lighting would be provided, per City and California Green Building Standards Code requirements. Furthermore, approximately 20,663 square feet of public open space would be provided on the ground floor of the building, including landscaping, seating areas and outdoor dining. A public plaza would be located at the corner of California Street and San Antonio Road as well as an outdoor seating area along Promenade Lane. In addition, approximately 17,715 square feet of private open space would be provided on site, including balconies and landscaping on the upper floors. It is expected that many of the employees would use the onsite open space areas for recreational purposes, which would minimize potential project-related effects on park facility ratios. With incorporation of the proposed open space, the project would ensure that the existing parkland-to-resident ratio would be maintained, which would minimize the potential for substantial park facility deterioration resulting from the increased employee population at the project site. Therefore, the proposed project’s impacts associated with existing recreational resources and the physical deterioration of them would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding existing recreational resources and physical deterioration that were analyzed in the SAPP EIR.
c. Would the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? The SAPP EIR found that impacts related to recreational facilities would be less than significant.
As described above and in Chapter 2, Project Description, the project would include both public and private onsite open space facilities, which would serve as recreational areas for many current and future employees at the project site. As described in the various sections of this document, these onsite recreational areas would not result in significant impacts. Therefore, the proposed project’s Attachment 1

impacts associated with the construction or expansion of recreational facilities that might have an adverse physical effect on the environment would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the construction or expansion of recreational facilities that were analyzed in the SAPP EIR.

3.12 Transportation and Traffic
a. Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? The SAPP EIR found that impacts related to conflicts with adopted policies, plans, or programs addressing the circulation system and alternative transportation would be less than significant with implementation of Mitigation Measure TRANS-1, (add a right turn lane at San Antonio Road/California Avenue for the westbound right turn movement or comparable improvement to maintain an acceptable intersection LOS), which has not yet been constructed.
Transit
The project site is within a 0.5-mile walk of rail and transit stops. The San Antonio Caltrain Station is approximately 0.25 mile north of the project site on Showers Drive and operates a total of 92 trains per day between San Jose and San Francisco. The Santa Clara Valley Transportation Agency (VTA) operates bus service within and surrounding the project area. Route 21 operates on Middlefield Road and California Street with two bus stops in the project area at the intersection of California Street and San Antonio Road, and California Street and Pachetti Way. In addition, Route 40 operates on Foothill Expressway and Rengstorff Avenue with one stop to the east of the project site at California Street and Showers Drive. Route 522 also operates near the project area along Manila Drive and Ellis Street.
Furthermore, the San Antonio Transit Center on Showers Drive at Latham Street is the transfer station for four regional bus routes (Routes 21, 22, 40, and 522) that serve Santa Clara County.
According to California Public Resources Code Section 21155, a major transit stop is defined as an existing rail or bus rapid transit station or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during peak commute periods. Therefore, the Project is in a transit proximity area because it is within 0.5 mile of a major transit stop. The proposed project’s Transportation Demand Management Plan would encourage and subsidize transit use; and therefore generate transit trips, consistent with state and local policies.

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.12-2 February 2022 ICF 104340.0.001.01
The new ridership generated by the project could be accommodated by existing services. Finally, the small number of new vehicle trips generated by the project would result in a minimal increase in vehicle delay at study intersections and would not cause a noticeable change in transit travel time or vehicle delay for the bus routes in the study area.
Roadway
In accordance with State CEQA Guidelines Section 15064.3(b) and CEQA Statute Section 21099(b)(2), level of service (LOS) is not used as a CEQA impact criterion in this addendum but is still used for planning purposes and is relevant outside of the CEQA process to evaluate other non- CEQA transportation impacts of development projects, such as congestion, circulation, and safety issues and concerns. An intersection LOS and delay assessment was completed as a part of the San Antonio Center Phase III Multimodal Transportation Analysis (MTA; see Appendix D of this Addendum) prepared by Fehr and Peers; however, for the reason cited above, the results are not evaluated in this addendum for CEQA purposes, and policies related to LOS are not considered as part of the policy consistency evaluation. However, because the City of Mountain View (City) considers this information relevant for planning purposes, summary results are included in Appendix D for informational purposes.
The project would not interfere with existing or planned roadway facilities. Furthermore, as detailed in the MTA (Appendix D), it would not conflict with currently adopted goals or policies. Therefore, the project’s impact on roadway facilities would be less than significant.
Bicycles
The project would not disrupt existing bicycle facilities. The existing bicycle lanes along California Street and San Antonio Road would be maintained. The project does not propose any new onsite or offsite bicycle pathways. Signs would be posted at the project driveways directing bicyclists to dismount and walk their bikes around the project site. The project would provide new Type I and Type II bicycle parking bicycle storage on site. In total, approximately 48 bicycle parking spaces would be provided on site, including 28 permanent bicycle lockers and 20 bicycle racks. Bicyclists would be able to access the permanent bicycle lockers and storage room via building access at the southeast corner at the intersection of San Antonio Road and California Street.
In the project vicinity, Silicon Way is a secondary bicycle facility, which is defined in the SAPP as including potential improvements to existing facilities and new bike facilities. These secondary facilities provide additional linkages to surrounding areas, including northern Mountain View and Palo Alto to the north, Rengstorff Park and Downtown Mountain View to the east, Downtown Los Altos to the south, and Palo Alto to the west. In addition, as detailed in the project’s MTA, a Level of Traffic Stress (LTS) analysis was conducted as part of the City’s comprehensive modal plan to measure the quality of a person’s experience while bicycling through the city. Low-stress bikeways (LTS 1 and 2) are generally tolerated by most cyclists, while high-stress bikeways are only tolerated by strong and fearless cyclists. Under existing conditions, Shoreline Boulevard and California Street are LTS 3 but with future conditions, including the project, both roadways would improve to LTS 2.
With the proposed bicycle facilities as part of the project in combination with future improvements planned under the SAPP, the LTS would be less stressful for most bicyclists in the Plan Area.
Therefore, based on the discussion above, the project site can be considered a location accessible to both experienced and recreational cyclists and the project would not conflict with a program, plan, ordinance, or policy addressing bicycle facilities.

Pedestrians
The project would not disrupt existing pedestrian facilities. Pedestrian access to the project site is currently provided by sidewalks on all streets immediately adjacent to the project site. Most sidewalks are 5 to 12 feet wide, and many of them have a landscaping strip separating the sidewalk from the street. In addition, all major intersections near the project site have crosswalks. Primary pedestrian routes, as defined by the SAPP, include San Antonio Road and California Street. Primary pedestrian routes provide active building frontages with pedestrian-scaled features and align with open space and other important destinations. Silicon Way, to the east of the project site, is a secondary pedestrian route. Secondary pedestrian routes provide new interior connections with limited pedestrian improvements.
Under the proposed project, pedestrian pathways would be provided around the exterior of the proposed building to promote circulation between the various commercial uses. The proposed pedestrian paths through the project site would provide access to the frontages of California Street and San Antonio Road and to the adjacent San Antonio Village Phase II buildings to the south and east. Additionally, the pedestrian paths would provide connectivity to the sidewalks on San Antonio Road and California Street. In addition, within a 15-minute walk of the project site under existing conditions, pedestrians are only able to access up to El Camino Real, but with future walking conditions including the proposed project, pedestrians would have access to a greater area of the city including the Mountain View Community Center with 10 to 15 minutes of walking from the project site. Therefore, with the project, the aforementioned destinations and existing pedestrian facilities would remain accessible and the project would not conflict with a program, plan, ordinance, or policy addressing pedestrian facilities.
Conclusion
Overall, the proposed project’s impacts associated with conflicts with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities, would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding conflicts with transportation programs, plans, ordinances, or policies, that were analyzed in the SAPP EIR. b. Conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b)? The transportation analysis that was prepared for the SAPP EIR followed the guidel ines of the City and VTA, which acts as the Congestion Management Agency for Santa Clara County. Potential transportation impacts were evaluated using the standards, methods, and significance criteria of these agencies. In addition, mitigation measures for identified significant impacts were identified where such measures were available and feasible. Because the SAPP EIR was certified in 2014, before Senate Bill 743 was adopted, the transportation impact evaluation at that time included LOS and not vehicle miles traveled (VMT ), as was required starting in 2020. The 2014 SAPP EIR included the San Antonio Village project. However, i n June 2020, the Mountain View City Council endorsed an approach for conducting V MT analysis for development projects that require transportation analysis citywide, in combination with requirements for a local -level analysis of multimodal transportation impacts. The City’s VMT Policy establishes screening criteria for developments that qualify as transit -supportive projects and are expected to result in a less -than- significant transportation impact under CEQA. Such projects are not required to prepare further VMT analyses. The City’s screening criteria are consistent with the guidance p rovided in the California Governor’s Office of Planning and Research’s 2018 Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR 2018).

Addendum to the San Antonio Precise Plan EIR for Precise Plan Amendments The Village at San Antonio – Phase III Project 3.12-4 February 2022 ICF 104340.0.001.01
The “proximity to transit” screening criterion applies to the proposed pr oject. The City defines this consistently with State CEQA Guidelines Section 15064.3, subdivision (b)(1), which states that lead agencies should presume that certain projects within 0.5 mile of an existing major transit stop or an existing stop along a hig h-quality transit corridor will have a less- than-significant impact on VMT.
The project site is within a 0.5-mile walk of rail and transit stops. The San Antonio Caltrain and Transit Station are approximately 0.25 mile north of the project site. The Transit Center, which includes a Caltrain Station and VTA bus service, is considered a major transit stop. More detailed analysis of VMT is recommended for projects that are within 0.5 mile of an existing major transit stop but meet certain exceptions. These exceptions include projects with a floor area ratio (FAR) of less than 0.75, projects that provide more than the maximum parking required by the City, projects that are inconsistent with the sustainable communities strategy (Plan Bay Area), or projects that replace affordable residential units with a smaller number of moderate- or high-income residential units. The project would have a FAR of 4.22 with the transfer of development rights program with Los Altos School District, and a FAR of 0.75 without the transfer of development rights. The project would provide fewer parking spaces than required by the City Zoning Code. The project is consistent with Plan Bay Area (MTC and ABAG 2017) because it would provide transit-oriented jobs by constructing a mixed-use commercial/office building in a transit-rich area as opposed to an auto- centric area, in addition to providing bicycle, carshare, and shuttle service facilities on site. The project would also implement transportation demand management programs to promote alternative modes of transportation and reduce vehicle trips and greenhouse gas emissions.
Therefore, the project qualifies as a transit supportive project and is consistent with Section 15064.3(b). Furthermore, the intersection operational analysis determined that the project would not cause the study intersections (listed on page 5 of the MTA; see Appendix D) to operate below their respective operational thresholds. In addition, based on the location of the project and the trip generation, distribution, and assignment, the project would not contribute more than 1 percent of the freeway mixed-flow or high-occupancy vehicle lanes’ capacity and a freeway analysis is not required. The proposed project is consistent with the findings in the SAPP EIR. Therefore, the proposed project’s impacts associated with inconsistency with State CEQA Guidelines 15064.3(b) would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding inconsistency with State CEQA Guidelines 15064.3(b) that were analyzed in the SAPP EIR.
c. Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The SAPP EIR found that impacts related to increased hazards due to a geometric design feature or incompatible uses would be less than significant.
Construction of the project would temporarily introduce construction equipment and vehicles to the project site and nearby street network. However, the project would be required to follow Standard Condition of Approval PW-135, Miscellaneous—Construction Management Plans, which requires the submission of a construction traffic and parking management plan that establishes truck routes.
PW-111 also ensures that sidewalks would remain accessible during construction. In addition, the project would be required to follow Standard Condition of Approval PW-36, Traffic Control Plans, which requires preparation of traffic control plans for any improvements that require lane, shoulder, bicycle land, and/or sidewalk closures. Adherence to these Standard Conditions of Approval would minimize potential traffic hazards during construction.

The project would not alter existing intersection lane configurations. Vehicular access to the project site would be provided from San Antonio Road and California Street, similar to under existing conditions. The project would include one entrance and one exit for the subterranean parking garage through the adjacent underground parking garage completed as part of the Phase II Village at San Antonio Center Project. Access to the joint underground garage is off San Antonio Road and under Silicon Way. Driveways that provide access to and from the project site would be required to adhere to Standard Conditions of Approval PW-44, Corner Street Sight Triangle, and PW-45, Driveway [or Side Street] Sight Triangle, which require vertical clearance at driveway locations to reduce hazards. Therefore, the proposed project’s impacts associated with hazards due to a project design feature would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding hazards due to a project design feature that were analyzed in the SAPP EIR. d. Result in inadequate emergency access?
The SAPP EIR found that impacts related to inadequate emergency access would be less than significant.
Emergency access to the project site would be provided from one location on California Street and one location on San Antonio Road (see Figure 2-5 in Chapter 2, Project Description, which shows the proposed access points). In addition, the internal streets of Silicon Way and Promenade Lane would provide full emergency access around the project site, as Silicon Way is approximately 22 feet wide and Promenade Lane is approximately 26 feet wide. Furthermore, the project design would be required to adhere to all applicable emergency access requirements and standards. These emergency access points would provide adequate access for emergency vehicles. Therefore, the proposed project’s impacts associated with emergency access would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding emergency access that were analyzed in the SAPP EIR.

The SAPP EIR found that impacts related to the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities would be less than significant with implementation of Mitigation Measures UTL-1, UTL-2, and UTL-3.
Existing water, stormwater, sanitary sewer system, natural gas, electricity, and telecommunications facilities (i.e., lines) would continue to serve the project site. New onsite facilities would be connected to new services through the installation of new, localized connections. Expansions or an Attachment 1

increase in capacity of offsite infrastructure would occur as required by the utility providers. Based on the proposed project onsite utility infrastructure described below, implementation of the project would result in construction of the following utility facilities. l Potable Water: Two 2-inch domestic water connections are proposed to connect to an existing 10-inch main in California Street. One of these connections would be connected in the future to recycled water mains once extended into the project area. In additio n, an 8-inch fire service would be connected to the 10-inch main in California Street. Further more, an existing
1.5-inch domestic water meter from San Antonio Road may be converted to an irrigation service or new 1.5 -inch irrigation service as part of the proposed project. The irrigation service line would be converted to recycled water when it becomes available to the project site and surrounding area.
l Stormwater: The proposed project would install two 8 -inch storm drains that would also connect to an existing 30-inch storm main in California Street. High -capacity bio-filtration best management practices would be used on the project site to treat stormwater. In add ition, planter boxes and a low-impact development (LID)-based treatment system would be used to treat stormwater runoff from the roof of the proposed building. Further more, proprietary biofiltration units and non-LID treatment systems would be used to treat ground -level stormwater runoff.
l Sanitary Sewer System : The proposed project would include a 6 -inch sanitary sewer connection to an existing 8-inch main in California Street. All other existing wastewater ut ility infrastructure would remain.
l Dry utilities (Electricity, Natural Gas, and Telecommunications) : The project proposes to construct new dry utility service connections. A 3- inch gas connection would be provided from San Antonio Road. All electrical and telecommunication utilities would be connected to existing electrical and telecommunication utilities in California Street.
As described in more detail in the impact discussions below, the proposed project would add flow to the existing sewer system ’s infrastructure deficiencies but would not increase the number of deficient pipes. In order to adequately accommodate wastewater flow from the proposed project, it is recommended that several pipes in the West Yost Capital Improvement Program (CIP ) are upsized from 10-inch- and 12-inch-diameter sewer pipes to 15 -inch-diameter sewer pipes.
Furthermore, there are several deficient pipes within the existing stormwater system downstream of the project site. However, the project would not result in additional deficiencies because the post-project peak flow would be only 3 percent higher than pre -project peak flow. To address the existing system deficiencies, the 2019 Storm Drain Master Plan recommends one CIP between San Antonio Road and Adobe Creek.
1 The CIP upsizes a 6.5 -foot-diameter storm drain pipe to an 8 - foot-diameter storm drain pipe to alleviate fl ooding during the 10 -year flooding event when Adobe Creek levels are high.
The installation or expansion of the aforementioned utility improvements would require excavation, trenching, soil movement, and other activities that are typical of development pr ojects in the Plan Area and Mountain View , as discussed in detail in this document as part of the assessment of overall project impacts. Project-specific impacts related to the construction or expansion of utilities as a component of the proposed project a re discussed in Section 3.1, Air

Quality (i.e., fugitive dust and criteria air pollutants), Section 3.10, Noise (i.e., ambient noise levels), and Section 3.9, Transportation and Traffic (i.e., transportation and circulation network).
In summary, impacts re lated to the construction of new utility facilities for the proposed project are addressed as part of the analysis of construction impacts for the proposed project as a whole.
The installation or expansion of any utility facilities for the project would no t result in additional significant impacts that are not otherwise disclosed elsewhere in this document or the San Antonio Precise Plan ( SAPP) EIR.
Based on the analysis above, the project would not require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects. Therefore, with SAPP EIR mitigation applied, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with the relocation or construction of new utility facilities would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding the relocation or construction of new utility facilities that were analyzed in the SAPP EIR. b. Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? The SAPP EIR found that impacts related to water supply would be less than significant with implementation of Mitigation Measure UTL-1.
The City municipal water system serves 98 percent of Mountain View, including the project site.
The Mountain View water system is divided into three pressure zones. Pressure Zone 1 is north of the Central Expressway, continuing to San Francisco Bay; Pressu re Zone 2 is between Cuesta Drive and the Central Expressway; and Pressure Zone 3 is south of Cuesta Drive. The project site is in Pressure Zone 2, which is supplied by two San Francisco Public Utilities Commission turnouts.
This supply can be supplemented with water from City -operated groundwater wells. Water demand in Pressure Zone 2 can be sufficiently supplied by the turnouts ; however, as discussed in the 2030 General Plan Update Utility Impact Study (GPUUIS ), surplus supply in Pressure Zone 2 would need to be routed to Pressure Zone 1 to make up the supply deficiency in the lower zone.
The remainder of Mountain View is served by the California Water Service Company. The City purchases water from both the Santa Clara Valley Water District and San Francisco Public Utilities Commission. In addition, water from four potable groundwater wells, which are owned and operated by the City, supplements these sources.
As stated in the SAPP EIR, ac cording to the Water Supply Assessment prepared for the SAPP, it is expected that even without development in the Plan Area, the City would have to rely on implementation of its Water Shortage Contingency Plan during some dry years to reduce demands. However, given the small amount of future growth associated with implementation o f the SAPP relative to that of the city by 2030, the City would not have to change its operation s or the implementation of the Water Shortage Contingency Plan in response to a drou ght, even after development associated with the SAPP is completed. In addition, development within the Plan Area is required to include a number of sustainability features, such as low -flow appliances and drought-resistant landscaping, to further reduce water consumption and conserve water.
Furthermore, consistent with the SAPP EIR Mitigation Measure UTL-1, the City requires project- specific capacity and condition s analyses of applicable water infrastructure adjacent and downstream of project sites .

As stated previously, w ater supply to the proposed project would be provided by two 2 -inch domestic water connections to an existing 10 -inch main in California Street. One of these connections would be connected in the future to recycled water mains once exte nded into the project area. In addition, an 8 -inch fire service would be connected to the 10 -inch main in California Street. Further more, an existing 1.5 -inch domestic water meter from San Antonio Road may be converted to an irrigation service or new 1.5 -inch irrigation service as part of the proposed project.
Water demand represents an established daily average water use pattern, which var ies by season and by customer type. Existing (baseline) water demand at the project site totals approximately 1,300 gallons per day (gpd ) and 1,934 gpd under future cumulative conditions . The pre-project (baseline) condition includes parcel -level demand, as adopted from the City’s InfoWater model and calibrated against water billing records from 2005 and 2006. The proposed project is expected to have a projected water demand of 17,012 gpd. The proposed project would increase water demand on site by approximately 15,712 gpd under existing conditions and 21,772 gpd under future cumulati ve conditions. The projected water demand does not exceed the SAPP EIR demand allocations under existing and future cumulative conditions ; therefore, it would not affect the City’s ability to meet total system water demand.
In addition, fire services for the proposed project are projected to have a water demand of 1,750 gallons per minute (gpm ) fire flow with an applied 50 -percent reduction for the assumed approval of an automatic sp rinkler system. It is likely that this is a conservative reduction estimate, as up to a 75-percent reduction is allowed upon approval of an automatic sprinkler system. The pre- project fire flow is set to 5,000 gpm based on parcel -specific fire flows identi fied in the 2010 Urban Water Management Plan.
2 This fire flow is not met at the existing hydrant location on California Street and San Antonio Road ; however, the anticipated project -specific fire flow requirement of 1,750 gpm would be met, as these deficie ncies are independent of the proposed project and show minimal (less than 1 percent) impact with project development. Several CIPs from the GPUUIS are in the vicinity of the project site and provide additional conveyance to the system, including CIP #31 on Miller Avenue and CIP #32 on California Street, which include upsizing 405 linear feet of a 10-inch-diameter pipe to a 12 -inch-diameter pipe, and upsizing 365 linear feet of an 8-inch-diameter pipe to a 12 -inch-diameter pipe, respectively.
The project-specific Utility Impact Study (Appendix E of this Addendum) concludes that the total projected water supplies available to the project site during baseline and future cumulative conditions are sufficient to meet the projected water demands for the project, in addition to existing uses. This demonstrates compliance with SAPP EIR Mitigation Measure UTL-1 requiring preparation of project -specific capacity and conditions analyses demonstrating available water supplies exist to support the proposed project. Therefore, with SAPP EIR Mitigation Measure UTL-1 applied, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with water supply would be less than s ignificant . The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding water supply that were analyzed in the SAPP EIR.

c. Result in a determination by the waste water treatment provider, which serves or may serve the project, that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
The SAPP EIR found that impacts related to wastewater services would be less than significant with implementation of Mitigation Measure UTL-2.
As explained in the SAPP EIR, the City entered into a joint agreement, referred to as the Basic Agreement, with the cities of Palo Alto and Los Altos in 1968 for the construction and maintenance of a joint sewer system, thereby addressing a need for the conveyance, treatment, and disposal of wastewater, in accord with Regional Water Quality Control Board requirements. Under the Basic Agreement, Palo Alto owns the Regional Water Quality Control Plant (RWQCP) and administers the Basic Agreement with the partnering agencies. It purchases individual capacity rights in terms of an average annual flow that can be discharged to the RWQCP. The City’s total capacity rights include flow leaving the city through the Shoreline Pump Station and the amount of flow that the City discharges into the Los Altos San Antonio Interceptor, per the 1970 Los Altos San Antonio Trunk Sewer Capacity agreement between the two cities.
Sewage generated within the city and Plan Area is treated at the RWQCP in Palo Alto. The sewer collection system is a gravity system, with the majority of flow discharging into three main trunk lines that convey flow from the south to the north and terminate at the Shoreline Pump Station within the City’s Shoreline Park. Flow is then pumped to the gravity Joint Interceptor Sewer that conveys flow to the RWQCP. The remaining flow not received at the Shoreline Pump Station is discharged to the Los Altos San Antonio Interceptor that also conveys flow into the Joint Interceptor.
The sewer system that serves the project site continues along California Street, north along Pachetti Way, west at the intersection of Pachetti Way and Sondgroth Way toward San Antonio Road, north along San Antonio Road, and ultimately flows to the Alma Recorder. The project would discharge into the 8-inch public sewer main from a 6-inch sanitary sewer connection at the project site.
Because the project would involve infill development, the proposed project’s impacts are evaluated by estimating the total sewer flow at the project site post-project and comparing it to the pre-project baseline sewer flow. Project-generated sewer flow was estimated using the square footage of the proposed building and is provided in Table 3.13-1 below.

Wastewater Treatment Capacity
According to the SAPP EIR, the remaining capacity at the Palo Alto RWQCP is sufficient to serve potential new development and redevelopment in the city as anticipated under the SAPP, which includes the proposed project. Consistent with SAPP EIR Mitigation Measure UTL-2, the City requires project-specific capacity and conditions analysis of applicable wastewater infrastructure to identify any impacts on the wastewater system and, as a condition of approval, the Public Works Department will determine and assign responsibility to project applicants for any necessary upgrades or improvements to the infrastructure. Therefore, with SAPP EIR mitigation applied, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with wastewater treatment capacity would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding wastewater treatment capacity that were analyzed in the SAPP EIR.
System Infrastructure
The proposed project would include a 6-inch sanitary sewer connection to an existing 8-inch main in California Street. All other existing wastewater utility infrastructure would remain. As detailed in the project-specific Utility Impact Study prepared by Schaaf & Wheeler (Appendix E of this Addendum), the sewer system does not have sufficient capacity downstream of the project for pre- project or post-project flows in existing conditions or future cumulative conditions. There are deficient pipes downstream of the project site along Pachetti Way, Sondgroth Way, and San Antonio Circle, with several of the deficient pipes surcharging. The project would add flow to these deficient pipes, but would not increase the number of deficient pipes.
The project site is within the portion of the city referred to as the Alma Recorder Area that contributes flow to the Los Altos Inceptor Sewer and has a contractual limitation of 2 million gpd of peak wet-weather flow. In existing conditions, pre-project flow to the Alma Recorder during peak wet weather is 14 percent below the contractual limit and would be 13 percent below the contractual limit post-project. In the future cumulative condition, pre-project flow to the Alma Recorder during peak wet weather would be 8 percent below the contractual limit pre- and post- project.
The total system-wide contractual capacity for Mountain View at the RWQCP in Palo Alto is evaluated in the existing and future cumulative conditions with increased project flows. When their respective service area reaches 80 percent of their contractual capacity rights, partnering agencies will agree to conduct an engineering study. The future cumulative condition estimates that the projected demand pre-project and post-project would exceed the 80-percent capacity threshold. The required engineering study when the City reaches 80 percent of its capacity shall redefine the anticipated future needs of the treatment plant.
In the Wastewater Capacity and Alignment Study El Camino Real & San Antonio Change Areas Project 14-48 (West Yost report) (West Yost 2017),3 the capacity of the sewer system within the Alma Recorder tributary area was evaluated and new infrastructure was recommended to divert flow from surcharged pipes along Sondgroth Way. The report identified several sewer mains along the project’s flow path that should be upsized, including pipes along San Antonio Circle and crossing Central Expressway.

In future cumulative conditions, the sewer system would not have adequate capacity either pre- or post-project with the CIPs recommended in the West Yost report. It is assumed that CIP #32 under the GPUUIS would be constructed under future cumulative conditions. An additional pipe from CIP #32 of the GPUUIS has been recommended to be upsized to meet the City’s flow requirements for pre-project conditions. In addition, it is recommended that the pipes in the West Yost CIPs are upsized from 10-inch- and 12-inch-diameter to 15-inch-diameter, as well as that an additional 8- inch-diameter pipe (Pipe ID 3737) be upsized to a 10-inch-diameter pipe to accommodate additional sewer flows.
Consistent with the SAPP EIR Mitigation Measure UTL-2, the City requires project-specific capacity and conditions analysis of applicable wastewater infrastructure to identify any impacts on the wastewater system and, as a condition of approval, the Public Works Department will determine and assign responsibility to project applicants for any necessary upgrades or improvements to the infrastructure. With incorporation of the recommended sewer upgrades identified above, the project would not result in new significant impacts. Therefore, with SAPP EIR mitigation applied, similar to those impacts identified in the SAPP EIR, the proposed project’s impacts associated with wastewater treatment infrastructure would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding wastewater treatment infrastructure that were analyzed in the SAPP EIR. d. Generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? The SAPP EIR found that impacts related to solid waste capacity would be less than significant.
Recology Mountain View (formerly known as Foothill Disposal) provides solid waste collection and recycling services for residents and businesses in Mountain View. Once collected, solid waste and recyclables are transported to the Sunnyvale Materials Recovery and Transfer station for sorting.
Small quantities of waste may be transported to other landfills in the area by private contractors.
Nonrecyclable waste from the Sunnyvale Materials Recovery and Transfer station is transported to the Kirby Canyon Landfill in San Jose. The Kirby Canyon Landfill has a permitted capacity of 36.4 million cubic yards, a remaining capacity of approximately 16.2 million cubic yards, and an anticipated closing date of December 31, 2059. The landfill receives a maximum of 2,600 tons of garbage per day (CalRecycle 2019). The estimated capacity accounts for all planned development through 2030.
As concluded in the SAPP EIR, new development and associated population and employment growth under buildout of the SAPP would increase demand for solid waste collection and disposal capacity.
A total of approximately 1,500 office employees would work at the project site upon completion and occupancy of the new building. Per the SAPP EIR, employees dispose of approximately 4.9 pounds of solid waste per person per day. Using this generation rate, the project would result in an increase of approximately 7,350 pounds per day of solid waste, or 1,341 tons per year. 4 The project would
result in a negligible increase in solid waste per day at the existing Kirby Canyon Landfill, which has a remaining estimated capacity of approximately 16.2 million cubic yards. These solid waste generation factors are estimates prior to recycling, composting, or other waste-diversion programs.
4 Assuming 1,500 net new employees and 4.9 pounds of waste per person per day (1,500 x 4.9 pounds/day= 7,350 pounds/day). Assuming 1 pound = 0.0005 ton (7,291 pounds/day x 365 days/year x 0.0005 ton= 1,341 tons/year).

Actual disposal rates could be lower because the project would ensure that sufficient solid waste facilities are available for use in compliance with Standard Condition of Approval PL-03 (Findings of Approval) and with the Village at San Antonio Center’s Trash Management Plan.5 Given the relatively high recycling rate of Mountain View and the Zero-Waste Plan goals, the project would not lead to a substantial burden on the existing Kirby Canyon Landfill.6 As described above, remaining capacity estimates at the Kirby Canyon Landfill account for all planned development, including the project.
Accordingly, the proposed project would not generate solid waste in excess of state or local standards or in excess of the capacity of local infrastructure, or otherwise impair attainment of solid waste reduction goals. Therefore, the proposed project’s impacts associated with solid waste generation would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding solid waste generation that were analyzed in the SAPP EIR.
e. Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
The SAPP EIR found that impacts related to compliance with solid waste regulations would be less than significant.
All collection, transport, and disposal of solid waste generated by the proposed project would comply with all applicable federal, state, and local statutes. The project would be required to comply with the City’s Construction and Demolition Ordinance, as required by Standard Condition of Approval PW-128 (Construction and Demolition Ordinance), and project construction would be required to comply with all applicable regulatory requirements related to solid waste.
Assembly Bill (AB) 341 requires commercial establishments to recycle. This law was extended by AB 1826 to require organics diversion for generators of organic waste (i.e., restaurants). State law also requires equal access to waste and recycling disposal locations. AB 1826 requires businesses and mixed-use residential developments that generate more than 4 cubic yards of solid waste per week to incorporate organic recycling programs, such as composting. To comply with City ordinances, AB 1826, and the Village at San Antonio Center’s Trash Management Plan, the project’s trash would be collected in four different streams: Waste, Dry Recyclables, Cardboard, and Compost.
Although up to approximately 7,350 pounds of solid waste per day would be generated, it is anticipated that some of that solid waste would be redirected in compliance with AB 1826. Actual disposal rates could be lower because the project would be required to ensure that sufficient solid waste facilities are available for use, in compliance with Standard Condition of Approval PL-03 (Findings of Approval). Operation of the project would be required to comply with federal, state, and local management and reduction statutes and regulations related to solid waste. Therefore, the proposed project’s impacts associated with compliance with solid waste regulations would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding compliance with solid waste regulations that were analyzed in the SAPP EIR.

f. Would the project result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Impacts to energy were discussed and analyzed in both the greenhouse gas (GHG) emissions and utilities and service systems sections of the SAPP EIR. The SAPP EIR found that impacts related to energy would be less than significant.
Construction
Construction of the project would include activities such as demolition, excavation, and foundation and building construction, which would require the use of trucks and other types of heavy equipment that would consume energy resources. Energy resources consumed during construction of the project primarily would result from the use of construction equipment (e.g., excavators) .
Construction activities for the project would result in a temporary increase in demand for energy.
However, the energy consumed during project construction would be considered a small, temporary increase in energy demand because construction activities would occur over an approximately 28- month period; therefore, energy consumption is considered short-term. Therefore, the proposed project’s impacts associated with the wasteful, inefficient, or unnecessary consumption of energy resources during project construction would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding energy consumption during project construction that was analyzed in the SAPP EIR.
Operation
The project design would incorporate numerous energy-efficiency features, including electric vehicle parking spaces and drought-tolerant landscaping. The project applicant intends to pursue Leadership in Energy and Environmental Design (LEED) Gold certification for the project and could incorporate features such as low-flow plumbing fixtures, Energy Star appliances, light-emitting diode (LED) technology, low-flow irrigation systems, bio-filtration planters, a highly efficient building envelope to mitigate solar heat gain, or below-grade parking to reduce the heat island effect.7 In addition, the project would incorporate Transportation Demand Management (TDM) measures, such as secure bicycle parking and subsidizing transit, carshare, walking and biking costs, which would reduce energy consumption in the form of diesel and gasoline from mobile vehicles. Therefore, the proposed project’s impacts associated with the wasteful, inefficient, or unnecessary consumption of energy resources during project operation would be less than significant. The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding energy consumption during project operation that was analyzed in the SAPP EIR. g. Would the project conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
Although the SAPP EIR did not have a separate analysis for energy and energy resources specifically, impacts to energy resources were discussed and analyzed in both the GHG emissions and utilities and service systems sections of the SAPP initial study and EIR, respectively. The SAPP EIR found that impacts related to conflicts with renewable energy or energy efficiency plans or measures would be less than significant.
7 According to the U.S. EPA, heat islands are urbanized areas that experience higher temperatures than outlying areas. Urban areas where structures, such as roads or buildings, are concentrated and landscaping or open space is limited, become islands of higher temperatures (between 1-7*F higher in the daytime, and 2-5*F higher during the nighttime), relative to surrounding areas (see: https://www.epa.gov/heatislands).

With incorporation of the previously mentioned energy-efficient and sustainable-design features, as well as the TDM measures, the project would be consistent with the City’s Green Building Code and the California Green Building Standards Code, as well as with measures outlined in the City’s Greenhouse Gas Reduction Progr am. The project would not conflict with or obstruct any state or local plans pertaining to energy efficiency. Therefore, the proposed project would have no impact associated with conflicts with applicable state or local renewable energy, or energy efficiency plans.
The proposed project would not result in new significant impacts or a substantial increase in the severity of impacts regarding conflicts with renewable energy or energy efficiency plans that were analyzed in the SAPP EIR.

Appendix 3.1. Methods for Analysis – Health Risk Assessment Diesel Particulate Matter Analysis
Diesel-powered construction equipment would emit DPM that could expose nearby sensitive receptors to increased cancer and non-cancer risks. Given that the proposed project would introduce DPM emissions to an area near existing sensitive receptors, a human HRA was performed using EPA’s most recent dispersion model, AERMOD (version 21112); chronic risk assessment values presented by OEHHA; and other assumptions for model inputs from BAAQMD’s Air Toxics NSR Program Health Risk Assessment Guidelines.1 The HRA takes into account OEHHA’s most recent guidance and calculation methods from the Air Toxics Hot Spots Program Guidance Manual for the Preparation of Risk Assessments.2 The HRA analyzes health risks to nearby sensitive receptors from construction activities. The human HRA consists of three parts: a DPM inventory, air dispersion modeling, and risk calculations. A description of each of these parts follows.
DPM Inventory
The DPM inventory includes mitigated emissions associated with short-term construction activity. The construction DPM inventory was assumed to be equal to the CalEEMod output results for diesel PM2.5 exhaust. The construction PM2.5 inventory was assumed to be equal to the CalEEMod output results for the sum of PM2.5 exhaust and fugitive dust. To quantify the project’s emissions in CalEEMod, the following methods were used.
Land uses that could be developed under the proposed project would generate construction-related emissions from mobile and stationary construction equipment exhaust, employee and haul truck vehicle exhaust, land clearing and material movement, paving, and application of architectural coatings. Criteria pollutant emissions were estimated using the California Emissions Estimator Model (CalEEMod) (version 2020.4.0). Construction schedule, material quantities, equipment operating details, and truck trip quantities were provided by the project applicant. These data were used to estimate construction emissions. Emissions from gasoline light duty vehicles (e.g., construction workers) were adjusted to account for the impact of the implementation of the SAFE Vehicles Rule. The CalEEMod outputs are provided in Attachment A.
Air Dispersion Modeling
The HRA uses EPA’s AERMOD to model annual average DPM and PM2.5 concentrations at nearby receptors. Modeling inputs, including emissions rates (in grams of pollutant emitted per second) and source characteristics (e.g., release height, stack diameter, plume width), were based on guidance provided by OEHHA and BAAQMD. Meteorological data were obtained from CARB for the Moffett Federal Airfield location, which is the nearest monitoring station, located approximately 3 miles east of the project site.
Construction equipment emissions were characterized as an area source (AREAPOLY) with a release height of 0.9 meters for fugitive dust emissions and 4.1 meters for all other emissions. One construction area

source was modeled, and haul and vendor truck emissions were characterized as line/area sources (LINEAREA) with a release height of 3.4 meters. Worker commute vehicles were also modeled as a line/area source with a release height of 1.3 meters. Emissions from off-road equipment were assumed to be generated throughout the construction footprint area. Emissions from off-site trucks were modeled segments adjacent to the construction footprint California Street and San Antonio Road.
The modeling of emissions from construction activities was based on the construction hours and days (7:30 a.m. to 4:00 p.m., five days per week) during 2022 through 2024. To account for plume rise associated with mechanically generated construction emissions sources for the AERMOD run, the initial vertical dimension of the area source was modeled at 3.81 meters; for the line/area sources, it was modeled at 3.16 meters.
The urban dispersion option was used based on the project site’s characteristics.
Offsite sensitive receptors were placed at individual homes in all directions within 1,000 feet of the construction work areas and haul roads. A 25-by-25-meter receptor grid was used to place receptors.
Risk Calculations
The risk calculations incorporate OEHHA’s age-specific factors that account for increased sensitivity to carcinogens during early-in-life exposure. The approach for estimating cancer risk from long-term inhalation, with exposure to carcinogens, requires calculating a range of potential doses and multiplying by cancer potency factors in units corresponding to the inverse dose to obtain a range of cancer risks. For cancer risk, the risk for each age group is calculated using the appropriate daily breathing rates, age sensitivity factors, and exposure durations. The cancer risks calculated for individual age groups are summed to estimate the cancer risk for each receptor. Chronic cancer and hazard risks were calculated using OEHHA’s 2015 HRA guidance.3 The risk calculations and additional assumptions are provided in Attachment B.
