In 2016, the City of Cupertino adopted the Bicycle Transportation Plan (Bike Plan), which is a citywide plan to encourage bicycling as a safe, practical, and healthy alternative to the use of the family car. The Bike Plan illustrates Cupertino’s current bicycle network, identifies gaps in the network, and proposes improvement projects to address the identified gaps.146 The Bike Plan includes standards for engineering, encouragement, education, and enforcement intended to improve the bicycle infrastructure in the city to enable people to bike to work and school, to utilize a bicycle to run errands, and to enjoy the health and environmental benefits that bicycling provides cyclists of every age. The Bike Plan recommends that the existing Class II Bike Lane on South Foothill Boulevard and Stevens Canyon Road through the project area be improved to a Class II Buffered Bike Lane. This recommendation is a low priority compared to other proposed projects in the Bike Plan.

The VTA adopted the Santa Clara Countywide Bicycle Plan (CBP). The CBP guides the development of major bicycle facilities in the County by identifying Cross County Bicycle Corridors and other bicycle projects of countywide or intercity significance. The CBP maps one on-street Cross-County Bicycle Corridor (CCBC) along South Foothill Boulevard in the project area. This CCBC is not a high-priority corridor.
Transit Facilities
VTA operates bus services in the City of Cupertino and in the project vicinity. The closest bus stop is located within a 15-minute walk (about 0.6 miles feet) to and from the project site, providing access to local bus route 81. Bus route 81 provides transportation between Moffett Field/Ames Center and San Jose State University. Bus route 81 operates from 6:06 a.m. to 9:04 p.m. and has a peak headway of 25 to 35 minutes depending on the stop and direction.

Daily Trips
Based on trip generation rates recommended by the Institute of Transportation Engineers (ITE) Trip Generation Manual, 9th Edition, it is estimated that the existing uses on site generate approximately 454 daily vehicle trips.148

As previously discussed in Section 3.1.3, Existing Site Setting, the project site currently contains 10,500 square feet of existing commercial development that generates up to 23 employees when assuming one employee per 450 square feet. The project site also includes one residential unit. As shown in Table 4-11, these uses generate daily VMT of 662 and an annual VMT of 241,524. 149

DISCUSSION
a) Would the project conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? Roadway Facilities
Operational Traffic
As previously discussed, the development of the project would not exceed the 15 dwelling units per acre currently permitted or the 25 dwelling units per acre maximum that was evaluated in the General Plan EIR. Therefore, the proposed project would not directly result in any additional new population growth or employment growth beyond what was analyzed in the General Plan EIR. As stated in Section II, Air Quality, and Section, VII, Greenhouse Gas Emissions, the proposed project is not considered a regionally significant project under CEQA Guidelines Section 15206 that would affect regional vehicle miles traveled (VMT) and warrant intergovernmental review by ABAG and MTC.
As shown in Table 4-12, the proposed project would generate 631 daily VMT, and 3230,315 annual VMT.
As shown in Table 4-13, the proposed project would generate about 322 daily trips.

When compared to existing conditions, the proposed project would generate both fewer daily trips (322 proposed daily trips compared to 454 existing daily trips), less daily VMT (631 proposed daily VMT compared to 662 existing daily VMT), and less annual VMT (230,315 proposed annual VMT compared to 241,524 existing annual VMT). Therefore, the project would generate fewer daily trips and fewer VMT than existing conditions and would have a net benefit with respect to roadway facilities.
The Governor’s Office of Planning and Research’s Technical Advisory On Evaluating Transportation Impacts in CEQA150 and the City’s White Paper SB 743 Implementation Decisions for the City of Cupertino151 provide guidance on evaluating transportation impacts for small projects, redevelopment projects on infill sites, and projects that are consistent with the Regional Transportation Plan (RTP)/Sustainable Community Strategy (SCS). According to the OPR, the proposed project is consistent with the following scenario that concludes with less-than-significant transportation impacts:
Where a project replaces existing VMT-generating land uses, if the replacement leads to a net overall decrease in VMT, the project would lead to a less-than-significant transportation impact.152 In addition, according to these guiding documents, a project that generates less than 110 daily trips may be assumed to cause a less-than-significant transportation impact.153 This threshold is based on CEQA’s categorical exemption154 for existing facilities (Class 1), including additions to existing structures of up to 10,000 square feet, so long as the project is in an area where public infrastructure is available to allow for maximum planned development and the project is not in an environmentally sensitive area (CEQA Guidelines Section 15301(e)(2)). Typical project types for which trip generation increases relatively linearly with building footprint (i.e., general office building, single tenant office building, office park, and business park) generate or attract an additional 110 to 124 average daily trips or 836 VMT per 10,000 square feet. 150 Governor’s Office of Planning and Research, Technical Advisory On Evaluating Transportation Impacts in CEQA, December 2018. 151 City of Cupertino White Paper SB 743 Implementation Decisions for the City of Cupertino, Appendix E: Appendix E, Small Project Screening for SB 743, February 2021. 152 Governor’s Office of Planning and Research, Technical Advisory On Evaluating Transportation Impacts in CEQA, page 17, December 2018. 153 Governor’s Office of Planning and Research, Technical Advisory On Evaluating Transportation Impacts in CEQA, December 2018, page 12 and City of Cupertino White Paper SB 743 Implementation Decisions for the City of Cupertino, Appendix E: Small Project Screening for SB 743, February 2021, pages 138 and 139. 154 Section 15300 of the CEQA Guidelines, Categorical Exemptions, states that Section 21084 of the Public Resources Code requires these Guidelines to include a list of classes of projects which have been determined not to have a significant effect on the environment and which shall, therefore, be exempt from the provisions of CEQA. 237

A 20-unit housing project generates an equivalent number of VMT to a 10,000-square-foot nonresidential project. 155 Therefore, absent substantial evidence otherwise, OPR and the City determined that it is reasonable to conclude that the addition of 20 housing units or 10,000 square feet of non-residential space could be considered a less-than-significant impact.
Furthermore, the OPR’s Technical Advisory On Evaluating Transportation Impacts in CEQA also recognizes that for redevelopment projects on infill sites, such as the proposed project, where a project replaces existing VMT-generating land uses, if the replacement leads to a net overall decrease in VMT, the project would lead to a less-than-significant transportation impact.156 This is consistent with CEQA Guidelines Section 15064.3(b), which states that projects that decrease VMT in the project area compared to existing conditions should be presumed to have a less-than-significant transportation impact.
On February 16, 2021, the City adopted CMC Chapter 17.08, Evaluation of Transportation Impacts Under the California Environmental Quality Act, which provides screening criteria and VMT thresholds for landuse development projects, transportation projects, and other projects pursuant to the CEQA. CMC Chapter 17.08 went into effect on April 1, 2021. Under CMC Chapter 17.08, a project would be screened out from more detailed VMT analysis if the project is consistent with applicable General Plan policies and supported by substantial evidence demonstrating cumulative VMT is declining. Project screening may be used for projects that meet one or more of the following criteria:
A project located within one-quarter mile of a High-Quality Transit Corridor or transit stop as defined by CEQA;
Local-serving retail of 50,000 square feet or less; or Land-use projects consisting of 100 percent affordable housing.
Under CMC Chapter 17.08, a project would have a significant impact if:
The total project generated VMT per service population would exceed the City’s target VMT reduction of 14.4 percent below the citywide baseline VMT rate, and If the project increases total countywide VMT compared to baseline conditions.
As described in Section X, Land Use and Planning, the proposed project is consistent with the General Plan and applicable policies. The proposed project, an infill redevelopment project currently served by existing public infrastructure and not in an environmentally sensitive area, would generate 631 daily VMT, which as described above is equivalent to the standards applied to a project qualifying for a CEQA exemption.
The proposed project would generate fewer VMT than existing conditions (proposed 631 daily VMT and 230,315 annual VMT compared to existing 662 daily VMT and 241,524 annual VMT), which demonstrates a contribution to a decline in cumulative VMT. Accordingly, the proposed project would meet the 155 Using statewide average data from the 2012 California Household Travel Survey (CHTS), the amount of daily VMT associated with 10,000 square feet of non-residential space is 836 VMT. Also using statewide average CHTS data, this level of VMT is associated with 20 housing units. 156 Governor’s Office of Planning and Research, Technical Advisory On Evaluating Transportation Impacts in CEQA, page 17, December 2018.

standards to be screened out from detailed VMT evaluation under the City’s standards as well as CEQA Guidelines Section 15064.3(b), which as previously stated finds that projects that decrease vehicle miles traveled in the project area compared to existing conditions should be presumed to have a less-thansignificant transportation impact. Accordingly, transportation impacts during operation of the proposed project would be less than significant.
Construction Traffic
Demolition and construction would take place over a 10-month period, which is anticipated to begin in June 2021 and end in March 2022, subject to regulatory approval. During this period, the project would result in changes to existing transportation conditions. New traffic would be generated by construction employees and construction activities, including haul trucks. Construction traffic is temporary and would generate fewer trips than the projected trips during project operation. During demolition and construction, vehicle, equipment, and materials would be staged and stored on a portion of the project site. The construction site and staging areas would be clearly marked, and construction fencing would be installed to prevent disturbance and safety hazards. No staging would occur in the public right-of-way.
Therefore, no hazards for pedestrians and bicyclists in the area would occur during this phase.
Pedestrian Facilities
The proposed project is expected to increase the number of pedestrians using the existing sidewalks and crosswalks in the area. The project site and surrounding uses would continue to use the existing sidewalks along Stevens Canyon Road, McClellan Road, and St. Andrews Avenue. The project would construct new sidewalks along the west side of South Foothill Boulevard and Stevens Canyon Road. The proposed sidewalk would also connect to the existing sidewalk to the north of the project site on west side of South Foothill Boulevard and existing sidewalk to the south of the project. The proposed project would have 5- foot sidewalks along Stevens Canyon Road, on the project side. The proposed project is expected to improve overall pedestrian access and facilities by providing sidewalks and ADA compliant ramps at existing crosswalkswithin the project vicinity with adequate accessible design (per the ADA) that meets the City of Cupertino design standards. The proposed project provides adequate and appropriate facilities for safe non-motorized mobility. Pedestrians would have safe access to the site via the existing crosswalks marked with ladder stripping on Stevens Canyon Road connecting to McClellan Road and St. Andrews Avenue. The proposed project would contribute to the pedestrian facilities in the project vicinity and would not eliminate or impede any existing pedestrian facilities, nor would it conflict with any of the goals and policies in the City’s Pedestrian Plan.
Bicycle Facilities
Class II Bike Lanes are located along both sides of the roadway at South Foothill Boulevard and Stevens Canyon Road in the vicinity of the project site. The proposed project would not remove any existing bicycle facilities, nor would it conflict with any adopted plans or policies for new bicycle facilities. The proposed project would be required to provide Class 1 bicycle parking spaces (bicycle lockers or secure rooms) and Class 2 bicycle parking spaces (publicly accessible bicycle racks) for commercial users and 239

employees of the mixed-use building. Therefore, the proposed project would not obstruct or hinder the implementation of the City’s Bike Plan and would support the use of bicycling by providing adequate bike facilities for commercial users and employees of the mixed-use building.
Transit Facilities
VTA operates bus services in the City of Cupertino and in the project vicinity. The closest bus stop is located within a 15-minute walk (about 0.6 miles feet) to and from the project site, providing access to local bus route 81. The VTA has not established policies or significance criteria related to transit vehicle delay. The 52 residents and 10 permanent jobs that would result from construction and operation of the proposed project are anticipated to come from Cupertino and surrounding Bay Area communities and would not introduce new riders to the VTA operated bus services that serve the project area. Therefore, the new transit trips generated by the project are not expected to create demand in excess of the transit service that is currently provided.
Conclusion
In summary, the proposed mixed-use, infill project would be expected to generate 132 fewer daily vehicle trips, 31 fewer daily VMT, and 11,209 fewer annual VMT than the existing use. The proposed project would not displace modify or interfere with any sidewalk, bicycle lanes, or sidewalks. In addition, the project would not generate a demand for transit that would exceed the capacity of the system. Therefore, the project would not conflict with adopted policies, plans, or programs regarding pedestrian, bicycle or pedestrian facilities. Accordingly, impacts would be less than significant. b) Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)? CEQA Guidelines Section 15064.3, which took effect on July 1, 2020, contains new requirements for evaluating a project’s transportation impacts. As of July 1, 2020, impacts on auto delay or level of service are no longer be considered a significant impact under CEQA for land use projects.
VMT measures the overall effects of a project on the transportation system. VMT is the sum of all of the vehicle trips generated by a project multiplied by the lengths of their trips to and from the site on an average weekday. A vehicle driven 1 mile is 1 VMT. Therefore, a project with a higher VMT would have a greater environmental effect than a project with a lower VMT.
The trip lengths vary by the land use type and the trip purpose. For example, a trip from a residence to a job may be longer than the trip from a residence to a neighborhood school. The VMT values stated below represent the full length of a given trip, and are not truncated at city, county, or region boundaries.
Many factors affect travel behavior and trip lengths such as density of land use, diversity of land uses, design of the transportation network, distance to high-quality transit, and demographics. Low-density development separated from other land uses and located in areas with poor access to transit generates more automobile travel and higher VMT compared to development located in urban areas with more access to transit. As discussed in the General Plan EIR, the VMT per capita is projected to increase from 240

10.5 to 10.9 under General Plan buildout conditions. The proposed project would construct a mixed-use project, which is consistent with the land use evaluated in the General Plan EIR and would not directly result in any additional new population growth or employment growth beyond what was accounted for in the General Plan EIR. Accordingly, implementation of the project would be consistent with and would have no effect on the VMT estimates presented in the General Plan EIR.
As discussed in criterion (a), the proposed project would be consistent with the analysis conducted in the General Plan EIR, and implementation of the proposed project would reduce VMT from the existing conditions at the project site. Therefore, the proposed project would not conflict or be inconsistent with CEQA Guidelines Section 15064.3(b) and impacts would be less than significant. c) Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The project proposes a two-lane entrance/exit circulation pattern with the access points on South Foothill Boulevard and Stevens Canyon Road, which is the same as how the site is currently accessed. As discussed in criterion (a), the proposed project would generate fewer daily trips than the existing conditions and would not create a significant impact on the expected left-turn or right-turn queues or sight distance at the study intersections.
The proposed project would not modify any design features to a public road or introduce a potentially unsafe feature that would increase hazards. No impacts would occur, and no mitigation measures would be required.
d) Would the project result in inadequate emergency access? The proposed project is located in a predominately residential neighborhood with residential driveways and neighborhood streets adjacent and in close proximity to the project site. There are three streets in the proposed project: McClellan Road extension, St. Andrews Avenue extension, and a new roadway on the project site to connect the streets. Service and emergency vehicles would be accommodated with two access points as well as sufficiently wide aisle ways for entering and turning. The internal circulation was reviewed for issues related to queueing, turning radii, safety and circulation aisles. All circulation aisles are 20 feet wide, and the turning radii are adequate for emergency and service vehicles. The SCCFD and City of Cupertino Building Division coordinate the review of building permits. All access driveways would be designed in accordance with City of Cupertino standards and would have to be reviewed and approved by SCCFD.
Project plans include approved fire and emergency access through all phases of construction and operation. Compliance with the provisions of the CFC and the CBC (described above), would ensure that adequate access would be provided. Therefore, the proposed project would not result in inadequate emergency access, no impacts would occur, and no mitigation measures would be required. 241

GENERAL PLAN EIR
As described above in Section IV, Cultural Resources, the General Plan EIR addressed impacts to cultural resources associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. The impacts were found to be less than significant, and no mitigation measures were required. The cultural resources study prepared for the General Plan EIR consists of archival research at the Northwest Information Center at Sonoma State University, examination of the library and files, field inspection, and contact with the Native American community. The cultural resources study addressed impacts associated with archeological resources, including those of Native Americans. As shown in Table 4.4-2, Cultural Resourcesin the Project Study Area and Vicinity, and on Figure 4.4-1, Cultural Resources, of the General Plan EIR, there are no identified cultural resources, including those affiliated with Native Americans, present on the project site.
EXISTING CONDITIONS
CEQA Sections 21074 and 21084.2 contain CEQA standards of significance that relate to Native American consultation and added “tribal cultural resources” to the specific cultural resources protected under CEQA. CEQA sections 21080.3.1 requires the CEQA lead agency to begin consultation with any California Native American Tribe that is traditionally and culturally affiliated with the geographic area of a proposed project if the Tribe requests in writing, to be informed by the lead agency through formal notification of 242

the proposed projects in the area. The consultation is required before the determination of whether a negative declaration, mitigated negative declaration, or EIR is required. In addition, CEQA Section 21080.3.1 includes time limits for certain responses regarding consultation. Pursuant to CEQA Section 21084.3, public agencies shall, when feasible, avoid damaging effects to any tribal cultural resources.
Information shared by tribes as a result of consultation shall be documented in a confidential file, as necessary, and made part of a lead agency’s administrative record. The City of Cupertino has not received a request from any Tribes in the geographic area with which it is traditionally and culturally affiliated with or otherwise to be notified about projects in the city.
CEQA Section 21074.3(a) defines a tribal cultural resource as a site, feature, place, cultural landscape that is geographically defined in terms of size and scope, sacred place, and object with cultural value to a California Native American tribe that is either included or eligible for inclusion in the California Register of Historic Resources or included a local register of historical resources, or if the City, acting as the lead agency, supported by substantial evidence, chooses at its discretion to treat the resource as a tribal cultural resource.
DISCUSSION
a) Would the proposed project cause a substantial adverse change in the significance of a Tribal Cultural Resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American Tribe, and that is:
i) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k), or ii) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resource Code Section 5024.1. In applying the criteria set forth in subdivision (c) of the Public Resource Code Section 5024.1 for the purposes of this paragraph, the lead agency shall consider the significance to a California Native American tribe? The discussion in Section IV, Cultural Resources, is applicable to impacts to tribal cultural resources. As discussed under criteria (b) and (c) in Section IV, Cultural Resources, no known archeological resources, ethnographic sites, or Native American remains are located on the project site. As discussed under criterion (b), implementation of Mitigation Measure CULT-1 would reduce impacts to unknown archaeological deposits, including tribal cultural resources, to a less-than-significant level. As discussed under criterion (c), compliance with State and federal regulations would reduce the likelihood of disturbing or discovering human remains, including those of Native Americans. Therefore, implementation of Mitigation Measure CULT-1, which is not a General Plan EIR mitigation measure, and compliance with State and federal regulations related to the protection of human remains would reduce impacts to tribal cultural resources to a less-than-significant level.
Impact TRC-1: The proposed project could cause a substantial adverse impact to an unknown Tribal Cultural Resource.

Chapter 4.14, Utilities and Services Systems, of the General Plan EIR, addressed the impacts to water supply, wastewater, and solid waste associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Impacts were found to be less than significant with mitigation. The City is required to implement General Plan Mitigation Measures UTIL-6a through UTIL-6c, and UTIL-8, which were previously adopted and incorporated into the General Plan, to ensure impacts related to wastewater and solid waste are less than significant. General Plan Mitigation Measures UTIL-6a through UTIL-6c require the City to work with the Cupertino Sanitary District (CSD) to increase the available citywide treatment and transmission capacity, identify appropriate and current wastewater generation rates that are approved by CSD and establish a monitoring and tracking system for wastewater generation to better understand the City’s need for potential capacity upgrades from CSD. General Plan Mitigation Measure UTIL-8 requires the City to continue current recycling and zero-waste practices, monitor solid waste generation, and seek new landfill sites to replace the Altamont and Newby Island landfills at such time that these landfills are closed. These mitigation measures, which were previously adopted by the City and incorporated into the General Plan, will be implemented by the City.

Cupertino Sanitary District (CSD) provides sanitary sewer services for the project site. Wastewater would be treated at the San José/Santa Clara Water Pollution Control Plant (SJ/SCWPCP). Recology South Bay (Recology) would provide curbside recycling, garbage, and compost and yard waste service to the residents of the project. The City has a contract with Newby Island Sanitary Landfill (NISL)157 until 2023. According to CalRecycle, the landfill had a remaining capacity of 21,200,000 cubic yards as of October 31, 2014 and a permitted maximum disposal capacity of 4,000 tons per day.158 The landfill is scheduled to operate until 2041. In 2019, the landfill accepted 582,174 tons of waste, which equates to approximately 1,940 tons/day.159 This results in a residual capacity of about 2,060 tons/day.
Electricity and natural gas would be supplied to the project site via infrastructure maintained by Pacific Gas & Electric (PG&E). Electricity would be supplied by Silicon Valley Clean Energy. Telephone service would be provided by AT&T and other providers. Cable television service would be available from numerous providers, including Comcast.
DISCUSSION
a) Would the project 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 of which could cause significant environmental effects? Water Treatment Facilities
The Santa Clara Valley Water District (SCVWD) operates three treatment plants. The Rinconada Water Treatment Plant, which serves the project site, draws water from the South Bay Aqueduct and the San Luis Reservoir, which is treated and supplied to residential and commercial water dealers, such as SJW, which serves the site. The plant can provide up to 80 million gallons of water per day. The water treatment plant 157 City of Cupertino, Garbage and Recycling Services Fact Sheet, http://www.recyclestuff.org/Guides/CityGuideCupertino.pdf, accessed May 7, 2019. 158 Calrecycle website, http://www.calrecycle.ca.gov/SWFacilities/Directory/43-AN-0003/Detail/, accessed May 29, 2019. 159 Assuming 300 operational days/year; the landfill is open six days a week. 245

is currently under renovation to modernize the system and will result in an increased capacity of 100 million gallons per day as well as improved water quality and greater seismic stability.160 As discussed in the General Plan EIR and criterion b) below, buildout of the General Plan including the proposed project would not result in insufficient water supplies from SJW under normal year conditions or during single-dry year and multiple-dry years, with the proposed and existing water conservation regulations and measures in place. Therefore, implementation of the project would not require any new water treatment facilities or improvements other than those currently under construction.
Wastewater Treatment Facilities
Wastewater from the project site would be discharged to the CSD sewer collection system, which the conveys the wastewater to the SJ/SCWPCP, which is jointly owned by the cities of San José and Santa Clara. The NPDES permit for this facility (NPDES No. CA0037842) is currently in the process of being renewed by the San Francisco Bay RWQCB (Tentative Order No. R2-2020-XXXX). The NPDES permit allows for dry weather discharges of up to 167 million gallons per day (mgd) with full tertiary treatment. The plant is designed to route fully treated secondary effluent in excess of the filtration design capacity around the filters (250 mgd) during extreme wet weather flow events and recombine it with filter effluent prior to disinfection. As discussed below in criterion (c), future demands from the proposed project would not exceed the design or permitted capacity of the SJ/SCWPCP that serves the project site. Future wastewater treatment demand was assessed in consultation with the City of Cupertino and includes consideration of development in the city through the 2040 buildout horizon of the General Plan. Therefore, development of the proposed project would not require any improvements not already considered, and the impact of the proposed project on SJ/SCWPCP would be less than significant.
Stormwater Drainage
Municipal storm water discharges in the City of Cupertino are subject to the Waste Discharge Requirements of the Municipal Regional Permit (MRP; Order Number R2-2015-0049, as amended by Order No. R2-2019-0004) and NPDES Permit Number CAS612008. As previously discussed in Section IX, Hydrology and Water Quality, the proposed project would be subject to Provision C.3 guidelines for stormwater control. Through C.3 compliance, the proposed project would minimize runoff from the project site as described in Section IX, Hydrology and Water Quality. The proposed project also would comply with CMC Chapter 9.18, described in Section 3.1.4.2, Zoning, which implements the requirements of the NPDES permit issued to the City. Additionally, the project would submit an SMP to the City for review and approval prior to the start of construction that describes the stormwater treatment measures that would be implemented to reduce stormwater runoff to the City’s storm drain system.
The project site is within an area where some of the storm drains are deficient in conveying the water from a 10-year storm, based on the 2018 Storm Drain Master Plan. Stormwater from the southern portion of the site would discharge to the City’s existing 18-inch storm drain that is aligned beneath St. Andrews 160 Santa Clara Valley Water District, 2020.

Avenue; this storm drain does not currently have capacity issues. However, stormwater from the northern portion of the site would discharge to the City’s existing 18-inch storm drain near the intersection of South Foothill Boulevard and McClellan Road. The storm drain beneath Stevens Canyon Road/South Foothill Boulevard that continues to Stevens Creek Boulevard is currently under capacity and is designated as high priority for replacement.161 The proposed project would not exacerbate this existing condition, however, because it will increase the amount of pervious surfaces through landscaping and reduce the amount of impervious surfaces, resulting in a net reduction in stormwater runoff. Additionally, the project would provide two bioretention facilities that would collect runoff from roof areas, parking lots, sidewalks and streets for treatment and flow control prior to discharge into the internal storm drain system, which connects to the City’s storm drain system at Stevens Canyon Road/South Foothill Boulevard and St.
Andrews Avenue. The City has determined that the on-site stormwater treatment areas would meet the C.3 requirements of the MRP. In addition, a hydrology and hydraulics report will be prepared for submittal and review by the Director of Public Works prior to the start of construction to ensure that the stormwater runoff from the site does not exceed the capacity of the City’s storm drain system.
The proposed project would not require the expansion of existing stormwater facilities or the construction of new facilities, the construction of which could otherwise have significant impacts. Therefore, impacts would be less than significant, and no mitigation measures would be required.
Other Utility Facilities
Other utility facilities that serve the project site include electric power, natural gas, and telecommunications facilities. PG&E would supply natural gas and electricity infrastructure and Silicon Valley Clean Energy would provide electricity to the project site. AT&T and other providers would provide telephone service. Cable television service would be available from numerous providers, including Comcast.
The proposed project is an infill development project that would result in an increase in land use intensity in a portion of the city that has access to existing infrastructure and services, which was accounted for in the General Plan EIR. The proposed project would include appropriate on-site infrastructure to connect to the existing PG&E and telecommunication systems and would not require new off-site facilities and distribution infrastructure or capacity enhancing alterations to any existing facilities. Accordingly, impacts would be less than significant.
b) Would the project have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? As described in the General Plan EIR in Chapter 4.14, the water supply for the City of Cupertino at project buildout year 2022 would be 13,078 acre-feet162 per year (afy) and at General Plan buildout year 2040 would be 16,984 afy. Buildout associated with the General Plan would result in sufficient water supplies 161 Schaaf & Wheeler Consulting Civil Engineers. 2018.

from SJW under normal year conditions or during single-dry year and multiple-dry years, with the implementation of proposed and existing water conservation regulations and measures. The Water Supply Evaluation prepared for the General Plan EIR included new development on the project site at a greater number of units than proposed for the project (27 net new units as compared to 18 new units for the proposed project); therefore, water supply impacts were adequately addressed in the General Plan EIR.
The proposed project’s water demand was calculated using the applicable water demand generation factors included in the Cupertino Sanitary District’s Flow Modeling Analysis. 163 For the residential
component of the project, a total indoor residential water demand of 155 gallons/day/unit was calculated.
For the commercial portion of the property, the water demand factor of 0.11 gpd/square foot from the Water Supply Evaluation prepared for the General Plan Amendment was used. The irrigation demand was based on the Maximum Applied Water Allowance (MAWA) pursuant to the Water Efficient Landscape Ordinance. This conservatively assumes that all the pervious area at the site will be irrigated; actual irrigation water usage will most likely be less than the calculated amount. The results are provided in Table 4-14.

Development Type Water Demand Factor Size Water Demand

The projected water demand for the project would be approximately 3,928 gpd or 4.4 AFY. This is less than 0.03 percent of Cupertino’s water supply at buildout and the proposed project was accounted for in the General Plan EIR at a higher density land use and water demand rate. There is no shortage in water supply to the City of Cupertino by SJW under normal year, single-dry year, and multiple dry years.
Accordingly, the proposed project’s water demand would not exceed the available water supply in 2022 at project buildout or General Plan buildout by year 2040 and impacts to water supply under the proposed project would be less than significant.
c) Would the project result in a determination by the wastewater 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 calculated wastewater demand for the proposed project is provided in Table 4-15. The proposed project with 4,536 square feet of commercial space and 18 residential units would generate approximately 2,982 gallons/day of wastewater, or 0.0030 mgd of wastewater.

calculations are based on the residential water demand factor of 155 gpd/unit and the assumption that 95 percent of the water demand would result in wastewater generation. For the retail/commercial component of the project, the wastewater demand factor of 0.073 gpd/sq ft for retail/commercial land use from the CSD ‘s Flow Modeling Analysis was used.

The wastewater demand under existing conditions was also calculated to determine the net increase in wastewater demand with implementation of the proposed project. Based on the CSD’s Flow Modeling Analysis, the wastewater demand factor for retail and commercial uses of 0.073 gpd per square foot, and assuming that the existing commercial buildings total 13,225 square feet, the current wastewater demand would be 965 gpd or approximately 0.0008 mgd of wastewater. The proposed project would generate up to 2,982 gpd or approximately 0.0024 mgd of wastewater.164 Therefore, the proposed project would increase wastewater generation at the site by 2,017 gpd or 0.0016 mgd of wastewater. However, the estimated project wastewater demand would be much less than that generated for the proposed buildout of the site in the General Plan, which assumed 27 new units for a wastewater demand of 3,969 gpd. In addition, the wastewater demand calculations are conservative, because no credit is taken for water conservation measures that would be applicable with new construction, thus reducing the amount of wastewater generated.
The SJ/SCWPCP’s projected peak wet weather capacity stated in The San Jose Santa Clara Water Pollution Control Plant Master Plan, November 2013, is 450 mgd. The proposed project’s wastewater generation (0.0030 mgd) and the existing wastewater generated in the SJ/SCWPCP’s service area (110 mgd) would not exceed the SJ/SCWPCP’s current total peak wet weather capacity of 450 mgd. The ADWF capacity is 167 mgd pursuant to the most recent National Pollutant Discharge Elimination System (NPDES) permit for the SJ/SCWPCP (Order No. R2-2014-0034, NPDES No. CA0037842). Combined, the proposed project’s wastewater generation (0.0030 mgd) and the existing wastewater generated (110 mgd) would not exceed the SJ/SCWCP’s current ADWF capacity limits (167 mgd).
The CSD has a contractual maximum treatment allocation of 7.85 mgd with the SJ/SCWPCP. At the time of the General Plan EIR, the CSD estimated the existing wastewater generation rate for the City of Cupertino 164 Mark Thomas & Co.

to be 5.3 mgd and the proposed General Plan build-out would generate 7.2 mgd of wastewater.165 Combined, the existing wastewater flow (5.3 mgd) plus the proposed project (0.0030 mgd) would not exceed the City’s contractual allocation limits (7.85 mgd). Furthermore, the proposed mixed-use development was included within the 4,421 residential units and the 1,343,679 square feet of commercial land use evaluated in the General Plan EIR. Furthermore, as demonstrated in Table 1.1 in Section 1.2, Tiering Process, the and the site was originally assumed to have a higher density land use. Therefore, the project would not result in an exceedance of the City’s contractual agreement with SJ/SCWPCP and there would be no significant impact with respect to wastewater treatment capacity.
However, the CSD’s wastewater flows through a portion of the City of Santa Clara’s sewer system. The contractual agreement between CSD and the City of Santa Clara, for this portion of the Santa Clara sewer system, allows the City 13.8 mgd of capacity in the sewer system during peak wet weather flows. The existing CSD peak wet weather flow into the Santa Clara system is 13.14 mgd.166 However, the estimated wastewater generation from the proposed project and from other potential projects in Cupertino, as established by the General Plan and other approved projects, is approximately 14.61 mgd, which is the total capacity needed to serve the General Plan buildout.167 Therefore, the proposed project, and other approved and potential projects as established by the General Plan buildout, will require a reduction in sewer generation from the CSD system prior to flowing into the City of Santa Clara system, or additional capacity rights will need to be acquired from the City of Santa Clara.
Until such corrections to the system can occur, future projects in Cupertino, including the proposed project would exceed the 13.8 mgd contractual limit through the City of Santa Clara sewer system resulting in a potentially significant impact.
Impact UTIL-1: Implementation of the proposed project may result in a determination by the wastewater treatment provider, which serves or may serve the proposed project, that it does not have adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments.
Mitigation Measure UTIL-1: No building permits shall be issued by the City for the proposed Canyon Crossing Mixed-Use Project that would result in exceeding the permitted peak wet weather flow capacity of 13.8 mgd through the Santa Clara sanitary sewer system. The project applicant shall demonstrate, to the satisfaction of the City of Cupertino and Cupertino Sanitary District (CSD), that the proposed project would not exceed the peak wet weather flow capacity of the Santa Clara sanitary sewer system by implementing one or more of the following methods:
2. Reduce inflow and infiltration in the CSD system to reduce peak wet weather flows; or 165 City of Cupertino, General Plan (Community Vision 2015–2040, Appendix B: Housing Element Technical Report, 4.3 Environmental, Infrastructure & Public Service Constraints, page B-93. 166 Mark Thomas & Co.

3. Increase on-site water reuse, such as increased grey water use, or reduce water consumption of the fixtures used within the proposed project, or other methods that are measurable and reduce sewer generation rates to acceptable levels, to the satisfaction of the CSD.
The proposed project’s estimated wastewater generation shall be calculated using the generation rates used by the CSD in the Flow Modeling Analysis for the Homestead Flume Outfall to the City of Santa Clara, prepared by Mark Thomas & Co. Inc., dated December 6, 2019, unless alternative (i.e., lower) generation rates achieved by the proposed project are substantiated by the project applicant based on evidence to the satisfaction of the CSD. To calculate the peak wet weather flow for a 10-year storm event, the average daily flow rate shall be multiplied by a factor of 2.95 as required by CSD pursuant to their December 2019 flow modeling analysis.
Alternatively, if the prior agreement between CSD and the City of Santa Clara that currently limits the permitted peak wet weather flow capacity of 13.8 mgd through the Santa Clara sanitary sewer system were to be updated to increase the permitted peak wet weather flow, this impact would then be less than significant. If this were to occur prior to the City’s approval of building permits, then Mitigation Measure UTIL-1 would no longer be required to be implemented.
Significance with Mitigation: Less than significant. Implementation of Mitigation Measure UTIL-1 would guarantee that no development on the project site could occur that would exceed the 13.8 mgd peak wet weather flow contractual limit through the City of Santa Clara and CSD by ensuring that no building permit would be issued for any structures or units that result in the contractual limit being exceeded until: (1) additional capacity is available through the City of Santa Clara’s sewer system; (2) improvements are made to the CSD sewer system that reduce the peak wet weather flows that enter the City of Santa Clara system; (3) improvements are made on the project site that ensure the contractual limit is not exceed; or (4) the completion of any combination of these approaches that adequately addresses potential capacity issues. Accordingly, impacts would be less than significant with mitigation. d) Would the project 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 City contracts with Recology to provide solid waste collection services to residents and businesses in the city. The City has a contract with Newby Island Sanitary Landfill (NISL) until 2023, but has not secured a new landfill contract for landfill disposal after that date. However, according to the Integrated Waste Management Plan, the landfills in the County (including NISL where the City’s collected solid waste is currently being landfilled) have adequate disposal capacity beyond 2026 and NISL’s’ operational life has recently been extended to 2041.
168 The City, therefore, has options for landfill service once the City’s existing contract with NISL ends in 2023. In addition to the Newby Island Landfill, solid waste generated in Cupertino can also be disposed of at the Altamont Landfill and Resource Recovery facility, the Corinda Los Trancos Landfill, Forward Landfill Inc., Guadalupe Sanitary Landfill, Kirby Canyon Recycling and Disposal Facility, the Monterey Peninsula Landfill, Recology Hay Road, the Vasco Road Sanitary Landfill, the Zanker Material Processing Facility, and the Zanker Road Class III Landfill. 168 Santa Clara County Integrated Waste Management Plan, County of Santa Clara Environmental Resources Agency, 1996. 251

Waste management for the proposed project includes recycling and composting. Solid waste generated by construction of the proposed project would largely consist of demolition waste from the existing buildings as well as construction debris. The project would be required to comply with CMC Chapter 16.72, Recycling and Diversion of Construction and Demolition Waste, and the City’s Zero Waste Policy, which requires the recycling or diversion of at least 65 percent of all construction and demolition (C&D) waste by salvage or by transfer to an approved facility.169,170 Prior to the issuance of any demolition, grading, and/or building permits, the applicant is required to submit a properly completed Waste Management Plan to the Cupertino Public Works Department, Environmental Programs Division. The Waste Management Plan shall do the following:
Identify the materials to be diverted from disposal by recycling, reused on the project, or salvaged for future use or sale.
Specify if materials would be sorted on-site or mixed for transportation to a diversion facility. Identify the diversion facility where the material collected will be taken. Identify construction methods employed to reduce the amount of waste generated. Specify that the amount of materials diverted shall be calculated by weight or volume, but not by both.
Compliance with CMC Chapter 16.72 and the City’s Zero Waste Policy would reduce solid waste and construction-related impacts on landfill capacity.
Once the project is operational, there would be 52 residents and 10 employees at the site. In 2019, the City of Cupertino’s disposal rate for residents was 3.5 pounds per day (PPD) and for employees was 3.4 PPD. This is much than lower than the CalRecycle’s target rate of 4.3 PPD for residents and 8.1 PPD for employees.171 The City of Cupertino’s disposal rates for residents and employees have been below target rates and decreasing since 2007, with the exception of 2014, when the rate (9.8 PPD) exceeded the target (8.10 PPD).172 Applying these disposal rates, the project would generate approximately 211 PPD or 0.11 tons per day of new waste. The Newby Island Sanitary Landfill has a permitted daily disposal capacity of 4,000 tons per day and in 2019, the average daily disposal rate was approximately 1,940 tons/day.
Therefore, the residual daily landfill capacity of 2,060 tons/day is more than sufficient to meet the solid waste generation rate for the project of 0.11 tons/day. Additionally, the proposed project would comply with the City’s current recycling ordinances and zero-waste policies, which would further reduce solid waste disposed of in the landfill. Therefore, implementation of the project would not generate solid waste 169 Cupertino Municipal Code, Title 16, Buildings and Construction, Chapter 16.72, Recycling and Diversion of Construction and Demolition Waste, Section 16.72.040, Diversion Requirement. 170 City of Cupertino, Public Works, Garbage & Recycling, https://www.cupertino.org/our-city/departments/environmentsustainability/waste, accessed May 30, 2019. 171 CalRecycle. 2017.

in excess of State or local standards, or excess the capacity of the landfill, or otherwise impair the attainment of solid waste reduction goals and would be less than significant. e) Would the project comply with federal, state, and local statutes and regulations related to solid waste? The City’s per capita disposal rate for residents and employees in 2018 was 3.1 PPD and 3.2 PPD, respectively, which is below the 4.3 PPD and 8.1 PPD target rate established by CalRecycle.173 As part of the Countywide Integrated Waste Management Plan to address waste management conditions within Santa Clara County, Cupertino adopted a Source Reduction and Recycling Element (SRRE)174 and Household Hazardous Waste Element (HHWE)175 in compliance with the California Integrated Waste Management Act.176 The City has gone beyond the SRRE by implementing several programs, including the City’s and Recology’s organics or food waste collection program, and Environmental Recycling Day events offered to residents three times per year by Recology.
In December 2017, the City adopted a Zero Waste Policy.177 According to the Zero Waste Policy, the City will require, through the City’s waste hauling franchise agreement, steadfast and ongoing efforts by the City’s franchisee to maintain a minimum residential and commercial waste diversion rate of 75 percent with a goal of reaching and maintaining 80 percent by 2025. In 2019, the City’s solid waste diversion rate was 69 percent. These programs will be sufficient to ensure that future development in Cupertino, including the proposed project, would not compromise the ability to meet or exceed the State mandated target.
Construction and any demolition debris associated with the project would be subject to CMC Chapter
16.72, requiring that a minimum of 65 percent of C&D debris be diverted from landfill.178 In addition, the City’s Zero Waste Policy requires that all private construction projects that come through the City’s permitting process, and all City projects (through contract requirements), recover and divert at least 65 percent of the construction waste generated by the project. Compliance with applicable statutes and regulations would ensure that the impact would be less than significant, and no mitigation measures would be required.

Chapter 4.7, Hazards and Hazardous Materials, of the General Plan EIR, addressed the impacts to wildfire hazards associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Impacts were found to be less than significant, and no mitigation measures were required. This section of the Initial Study also addresses additional questions regarding wildfire related impacts pursuant to the updated CEQA Guidelines that were adopted by the California Natural Resource Agency in December 2018.
EXISTING CONDITIONS
Wildland fire protection in California is the responsibility of either the State, local government, or the federal government. State Responsibility Areas (SRA) are the areas where the State of California has the primary financial responsibility for the prevention and suppression of wildland fires. The SRA includes a 31-million-acre area, in which the State Department of Forestry and Fire Protection (CAL FIRE) provides a basic level of wildland fire prevention and protection services. Local Responsibility Areas (LRA) include lands within incorporated cities, cultivated agriculture lands, and portions of the desert. LRA fire protection is typically provided by city fire departments, fire protection districts, counties, or by CAL FIRE under contract to local government.179 CAL FIRE determines fire hazard zones within the LRA using an extension of the SRA Fire Hazard Severity Zone model as the basis. The LRA hazard rating reflects flame and ember intrusion from adjacent wildlands and from flammable vegetation in the urban area. 179 California Department of Forestry and Fire Prevention (CAL FIRE).

CAL FIRE designates fire hazard severity zones (FHSZs) as authorized under California Government Code Sections 51175 et seq. CAL FIRE considers many factors such as fire history, existing and potential fuel (natural vegetation), flame length, blowing embers, terrain, and typical weather for the area. There are three types of FHSZs: moderate, high, and very high.
According to the California Office of Emergency Services, a Wildland-Urban Interface (WUI) is defined as any area where structures and other human development meet or intermingle within wildland vegetation.180 Developments in the wildland-urban interface exacerbate fire occurrence and fire spread in several ways, including:
Increased numbers of human-caused wildfires.
Wildfires become harder to fight.
Firefighting resources are diverted from containing the wildfire to protecting lives and homes. Letting natural fires burn becomes impossible; leading to buildup of fuel, increasing wildfire hazard further.181
The project site is located within an LRA and the SCCFD currently provides fire protection and emergency medical services to the city and project site. The nearest SRA is approximately 0.5 miles to the west and is designated as a High FHSZ. The nearest Very High FHSZ within the Cupertino LRA is located approximately
1.5 miles to the southeast. The project site is not located within the Cupertino designated WUI.182 However, it is located within the CalOES defined WUI, which is an area of transition between wildland (unoccupied land) and land with human development (occupied land).; 183 therefore, impacts related to
wildfire are discussed below.
DISCUSSION
a) Substantially impair an adopted emergency response plan or emergency evacuation plan? The City of Cupertino Office of Emergency Services is responsible for coordinating agency response to disasters or other large-scale emergencies in the City of Cupertino with assistance from the Santa Clara County Office of Emergency Services and the SCCFD. The Cupertino EOP establishes emergency planning, mitigation, response, and recovery policies within the city.
As described in Section VIII, Hazards and Hazardous Materials, emergency vehicle access would be provided at two points on the project site and the proposed project would not block roads or impede emergency access to surrounding properties or neighborhoods during either construction or operation of the project. The Emergency Circulation Plan includes a fire truck circulation route in addition to designated fireman access routes to reach the rear of the structures.

vehicles, equipment, and materials would be staged and stored on a portion of the project site and no staging would occur in the public right-of-way.
As stated in Section VIII, Hazards and Hazardous Materials, the proposed project would not interfere or impair with an adopted emergency response plan, or emergency evacuation plan; therefore, impacts would be less than significant.
Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? As stated in Section 3, Project Description, of this Initial Study, the project site is classified as “urban area” under the CALVEG classification system and is surrounded by residential and other urban uses. The site is characterized as generally flat and surrounding by low topographic relief. Prevailing winds in Cupertino derive from the west from February to November, and from the north from November to February, with the windier part of the year occurring from March to July with wind speeds averaging 7.6 miles per hour.184 The project site is not located within an SRA or Very High FHSZ in an LRA. The project site is also not located within the Cupertino Wildland Urban Interface Fire Area as defined in CMC Chapter 16.74, Wildland Urban Interface Area Adopted.
The proposed landscaping includes a variety of low water use plants with shrubs and trees surrounding the exterior of the site, as shown in Figure 3-13. The proposed buildings and landscaping would be required to comply with CMC Chapter 9.22.020, Property Maintenance, which requires the upkeep of vegetation and landscaping on the properties to prevent fire and health hazards. CMC Chapter 16.40, Fire Code, would also require the proposed project to comply with the 2019 California Fire Code and 2015 International Fire Code, which provide specific regulations governing conditions hazardous to life and property from fire or explosion. Therefore, the proposed project would have fire prevention and management measures and would not expose occupants and the surrounding neighborhoods to pollutant concentrations or the uncontrolled spread of wildfire. Impacts would be less than significant, and no mitigation would be required.
Require the installation of maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines, or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?
As discussed in Section 3.1.1, Existing Site Character, of the Project Description, the project site is fully developed with commercial buildings and associated parking, and utility infrastructure already serves the project site. The proposed project would not include new roads, fuel breaks, or sources of emergency water. Overhead power lines are currently located above the eastern edge of the project site, and new power lines are not proposed as part of the project. Minor alterations such as water, natural gas, and sewer line piping would be installed to connect existing utilities to the proposed residential units.
Therefore, installation and maintenance of infrastructure would not exacerbate wildfire risks and new 184 Weather Spark. 2019. https://weatherspark.com/y/504/Average-Weather-in-Cupertino-California-United-States-YearRound, accessed June 3, 2019. 256

infrastructure would not cause temporary or ongoing impacts on the environment. Impacts would be less than significant, and no mitigation measures would be required.
Expose people or structure to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire instability, or drainage changes? As stated in criterion b), the project site is characterized as generally flat and is surrounded by low topographic relief. The project site is not located within a floodplain or an area that has a high potential for landslides. As discussed in Section IX, Hydrology and Water Quality, the proposed project would result in a 4,556 square foot decrease in the amount of impervious surface and provide 267 additional square feet of water treatment area through two bioretention areas that would hold and treat stormwater before it is released into the City’s off-site storm drain infrastructure, which will reduce runoff on the project site.
Therefore, the proposed project would not expose people or structures to flooding or landslides that result from post-fire instability and runoff, and impacts would be less than significant.

rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
The project site is in an urbanized and extensively developed area of Cupertino. The project site and surrounding area is entirely built out with existing commercial and residential development and associated surface parking. The project site is currently developed with commercial buildings that are partially vacant, and a vacant single-family home. Landscaping currently consists of a few green spaces with trees surrounding the buildings and the eastern edge of the project site. There are no identified sensitive natural communities, no areas of sensitive habitat, and no areas of critical habitat on the project site. In addition, there are no buildings currently listed or eligible for listing on the California Register of Historical Resources, no recorded archaeological sites, and no known paleontological resources located on the project site. The implementation of Mitigation Measures AQ-1, AQ-2, BIO-1, CULT-1, GEO-1, NOISE-1, NOISE-2, TCR-1, and UTIL-1 would serve to protect the quality of the air, nesting birds, and unknown cultural and tribal resources, as well as ensure adequate services are provided and that no additional physical impacts would occur elsewhere. Therefore, implementation of the proposed project would result in a less-than-significant impact to the quality of the environment, wildlife, and major periods of California history or prehistory.
b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?
CEQA Guidelines Section 15355 defines cumulative impacts as two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts.
Cumulative impacts may result from individually minor, but collectively significant projects taking place over a period of time. CEQA Guidelines Section 15130(b) advises that a discussion of cumulative impacts should reflect both the severity of the impacts and the likelihood of their occurrence. To accomplish these two objectives, CEQA Guidelines Section 15130 permits two different methods for completion of a cumulative impact analysis and allows for a reasonable combination of the two approaches:
The ‘list’ approach permits the use of a list of past, present, and probable future projects producing related or cumulative impacts, including projects both within and outside the city; and The ‘projections’ approach allows the use of a summary of projections contained in an adopted plan or related planning document, such as a regional transportation plan, or in an EIR prepared for such a plan. The projections may be supplemented with additional information such as regional modeling.

The General Plan EIR evaluated the cumulative effects of the General Plan Amendments, Housing Element Update, and Associated Rezoning using the summary of projections approach provided for in CEQA Guidelines Section 15130(b)(1)(B). The General Plan EIR took into account growth from the General Plan within the Cupertino city boundary and Sphere of Influence (SOI), in combination with projected growth in the rest of Santa Clara County and the surrounding region, as forecast by ABAG.
As provided for by CEQA Guidelines Section 15130, the cumulative context considered in the General Plan EIR varies, depending on the nature of the issue being studied, to best assess each issue‘s geographic extent. For example, the cumulative impacts on water and air quality can be best analyzed within the boundaries of the affected resources, such as water bodies and air basins. For other cumulative impacts, such as hazard risks, traffic, and the need for new public service facilities, the cumulative impact is best analyzed within the context of the population growth and associated development that are expected to occur in the region or the public service providers’ jurisdiction.
The General Plan EIR included an assessment of the redevelopment of the project site with mixed-use, with commercial and residential projects. The residential assumptions included a residential density of 25 dwelling units per acres with a 30-foot height maximum, which would result in up to 27 residential units.
Therefore, as shown in Table 4-16, when combined with the other reasonably foreseeable projects in Cupertino the project would not exceed the maximum buildout potential evaluated in the General Plan 259

EIR. The impact discussions in Section I through Section XVIII above describe the proposed project‘s relationship to and consistency with the scope of development, land use designations, population projections, and cumulative impacts analyses contained in the General Plan EIR. As shown, the project’s cumulative impacts were determined to be less than significant or less than significant with mitigation in the cumulative context.
Since the certification of the General Plan EIR, the City has considered new development at the Vallco project site. While, as shown in Table 4-16, this development at the Vallco site is consistent with the maximum buildout potential in the General Plan EIR for citywide cumulative discussions (e.g., population and housing, water supply, etc.), the General Plan EIR did not evaluate the specific amount of buildout at the Vallco site that is shown in Table 4-16, therefore, localized cumulative impacts such as traffic, traffic related noise, and utilities infrastructure were not captured in the General Plan EIR. Due to the distance between the proposed Canyon Crossings Mixed-Use Project and the Vallco project site, the proposed project’s impacts would result in no localized cumulative impacts related traffic, noise, or utilities in combination with development of the Vallco site.
As described in the environmental checklist, the impacts of the proposed project would be mitigated to less-than-significant levels. The proposed project would incrementally contribute to, but would not exceed, the cumulative impacts analyses included in the General Plan EIR. Therefore, the proposed project would not be expected to contribute to significant cumulative impacts when considered along with other impacts under the General Plan.
c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
As discussed previously, the proposed project would not result in a significant impact that could not be mitigated to a less-than-significant level, thus the proposed project’s environmental effects would be less than significant.

Mitigation Measure AQ-1: The project’s construction contractor shall comply with the following best management practices for reducing construction emissions of fugitive dust (PM10 and PM2.5) as required by the Bay Area Air Quality Management District Revised California Environmental Quality Act Air Quality Guidelines:
Water all active construction areas at least twice daily, or as often as needed to control dust emissions. Watering should be sufficient to prevent airborne dust from leaving the site. Increased watering frequency may be necessary whenever wind speeds exceed 15 miles per hour. Reclaimed water should be used whenever possible. Pave, apply water twice daily or as often as necessary to control dust, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites. Cover all trucks hauling soil, sand, and other loose materials. Sweep daily (with water sweepers using reclaimed water if possible) or as often as needed all paved access roads, parking areas and staging areas at the construction site to control dust. Sweep public streets daily (with water sweepers using reclaimed water if possible) in the vicinity of the project site, or as often as needed, to keep streets free of visible soil material.
Hydroseed or apply non-toxic soil stabilizers to inactive construction areas.
Enclose, cover, water twice daily, or apply non-toxic soil binders to exposed stockpiles (dirt/sand).
Limit vehicle traffic speeds on unpaved roads to 15 miles per hour. Replant vegetation in disturbed areas as quickly as possible and water appropriately until vegetation is established.
Install sandbags or other erosion control measures to prevent silt runoff from public roadways.
All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe.

authorized representatives that are assigned to respond in the event of a noise or vibration complaint. If the authorized contractor’s representative receives a complaint, they will investigate, take appropriate corrective action, and report the action to the City.
During the entire active construction period, equipment and trucks used for project construction will utilize the best available noise control techniques (e.g., improved mufflers, equipment re-design, use of intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds), wherever feasible.
Include noise control requirements for equipment and tools, including concrete saws, to the maximum extent feasible. Such requirements could include, but are not limited to, erecting temporary plywood noise barriers between construction areas and nearby sensitive receptors; performing work in a manner that minimizes noise; and undertaking the noisiest activities during times of least disturbance to nearby sensitive receptors. During the entire active construction period, stationary noise sources will be located as far from sensitive receptors as possible, and they will be muffled and enclosed within temporary sheds, or insulation barriers or other measures will be incorporated to the extent feasible.
During the entire active construction period, noisy operations will be conducted simultaneously to the degree feasible in order to reduce the time periods of these operations.
Select haul routes that avoid the greatest amount of sensitive use areas and submit to the City of Cupertino Public Works
Department for approval prior to the start of the construction phase.
Signs will be posted at the job site entrance(s), within the on-site construction zones, and along queueing lanes (if any) to reinforce the prohibition of unnecessary engine idling. All other equipment will be turned off if not in use for more than 5 minutes. During the entire active construction period and to the extent feasible, the use of noise producing signals, including horns, 269

whistles, alarms, and bells will be for safety warning purposes only.
The construction manager will use smart back-up alarms, which automatically adjust the alarm level based on the background noise level or switch off back-up alarms and replace with human spotters in compliance with all safety requirements and laws.
Mitigation Measure NOISE-2: Mechanical equipment shall be selected and designed to reduce impacts on surrounding uses to meet the Cupertino Municipal Code noise limits of 60 dBA and 50 dBA at residential uses during daytime and nighttime, respectively, and 65 dBA and 55 dBA at non-residential sensitive uses during daytime and nighttime, respectively. A qualified acoustical consultant shall be retained to review mechanical noise as these systems are selected to determine specific noise reduction measures necessary to reduce noise to comply with the City’s noise level requirements. Mechanical equipment shall be selected and designed to reduce impacts on surrounding uses to meet the City’s noise level requirements. Noise reduction measures could include, but are not limited to:
Selection of equipment that emits low noise levels;
Installation of noise dampening techniques, such as enclosures and parapet walls, to block the line-of-sight between the noise source and the nearest receptors; or
Locating equipment in less noise-sensitive areas, where feasible.

Mitigation Measure UTIL-1: No building permits shall be issued by the City for the proposed Canyon Crossing Mixed-Use Project that would result in exceeding the permitted peak wet weather flow capacity of
13.8 mgd through the Santa Clara sanitary sewer system. The project applicant shall demonstrate, to the satisfaction of the City of Cupertino and Cupertino Sanitary District (CSD), that the proposed project would not exceed the peak wet weather flow capacity of the Santa Clara sanitary sewer system by implementing one or more of the following methods:
Reduce inflow and infiltration in the CSD system to reduce peak wet weather flows; or
Increase on-site water reuse, such as increased grey water use, or reduce water consumption of the fixtures used within the proposed project, or other methods that are measurable and reduce sewer generation rates to acceptable levels, to the satisfaction of the CSD.
The proposed project’s estimated wastewater generation shall be calculated using the generation rates used by the CSD in the Flow Modeling Analysis for the Homestead Flume Outfall to the City of Santa Clara, prepared by Mark Thomas & Co. Inc., dated December 6, 2019, unless alternative (i.e., lower) generation rates achieved by the proposed project are substantiated by the project applicant based on evidence to the satisfaction of the CSD. To calculate the peak wet weather flow for a 10-year storm event, the average daily flow rate shall be multiplied by a factor of 2.95 as required by CSD pursuant to their December 2019 flow modeling analysis.

Background:
Application Requests
The applicant, Alan Enterprises, is requesting permits to allow the construction of singlefamily townhomes on a 0.63-acre site currently occupied by a commercial building. The project would demolish the existing commercial building and construct a nine (9) residential unit development including one (1) residential unit containing an accessory dwelling unit (ADU).
The following City permits would be required: Zone Map Amendment, Development Permit, Architectural and Site Approval, and Use Permit. A Vesting Tentative Map is proposed to divide the property from three (3) parcels to ten (10) parcels consisting of the nine (9) homes and one (1) common parcel. In addition, prior to approval of the permits, the City would need to adopt the Mitigated Negative Declaration as the appropriate environmental document for the project.
Site and Location Description
The project is located at the intersection of Stevens Creek Boulevard and Foothill Boulevard in the Inspiration Heights neighborhood area of the General Plan.
The property is bounded by
Stevens Creek Boulevard to
the north, South Foothill
Boulvard to the east,
Camino Vista Drive to the
west and resdiential singlefamily homes to the south.
Other surrounding land
uses include an office
development and a town
home development across
Stevens Creek Boulevard to
the north, a Veterinary
Clinic and single family
uses to the north east, a gas
station and single family
residential uses across S.
Foothill Boulevard to the east, and single family homes and the Monta Vista Fire Station across Camino Vista Drive to the west (see Figure 1).

The site has gross area of 0.78 acres, which after required dedications to accommodate required infrastructure and frontage improvements along Stevens Creek Boulevard and Footthill Boulevard, will have a net site area of 0.63 acres. The existing commerical building measures approximately 2,500 square feet.
Analysis:
General Plan and Zoning Compliance
The General Plan’s Community Form Diagram (Figure LU-2) establishes several development standards in the City, including height and density. The proposed site has a maximum height of 30 feet and the project has a proposed density of 11.5 dwelling units per acre (less than the maximum density of 15 dwelling units per acre.) The applicant has also applied for a Zone Map Amendment (Z-2020-001) to allow development of a residential uses on the site. It should be noted that the General Plan allows residential uses on the site. Additionally, because the project was not listed as a Priority Housing Site in the City’s General Plan: Community Vision 2015-2040 (General Plan), per the requirements of the General Plan and the Municipal Code, the project is required to obtain a Use Permit (U-2020-001) as part of the entitlement process.
Staff evaluated the project’s consistency with the General Plan and concluded that based on the site’s General Plan Land Use Designation (Commercial/Residential), the proposed Zoning Map Amendment, consultation with Economic Development staff, and the analysis of the Initial Study Mitigated Negative Declaration (further discussed in detail in the Environmental Review section of this Staff Report), the proposed project supports several of the City’s other General Plan goals including:
Policy LU-2.2: Pedestrian-oriented Public Spaces - Require developments to incorporate pedestrian-scaled elements along the street and within the development such as parks, plazas, active uses along the street, active uses, entries, outdoor dining and public art. Policy LU-3.1: Site Planning - Ensure that project sites are planned appropriately to create a network of connected internal streets that improve pedestrian and bicycle access, provide public open space and building layouts that support city goals related to streetscape character for various Planning Areas and corridors.
Policy LU-3.3: Building Design - Ensure that building layouts and design are compatible with the surrounding environment and enhance the streetscape and pedestrian activity. LU-3.3.1: Attractive Design - Emphasize attractive building and site design by paying careful attention to building scale, mass, placement, architecture, materials, landscaping, screening of equipment, loading areas, signage and other design considerations. 336

LU-3.3.5: Building Location - Encourage building location and entries closer to the street while meeting appropriate landscaping and setback requirements. Policy LU-3.4: Parking - In surface lots, parking arrangements should be based on the successful operation of buildings; however, parking to the side or rear of buildings is desirable. No visible garages shall be permitted along the street frontage. Above grade structures shall not be located along street frontages and shall be lined with active uses on the ground floor on internal street frontages. Subsurface/deck parking is allowed provided it is adequately screened from the street and/or adjacent residential development. Policy LU-27.2: Relationship to the Street: Ensure that new development in and adjacent to neighborhoods improve the walkability of neighborhoods by providing inviting entries, stoops and porches along the street frontage, compatible building design and reducing visual impacts of garages.
HE-1.3.4: Flexible Development Standards - The City recognizes the need to encourage a range of housing options in the community. The City will continue to:
Offer flexible residential development standards in planned residential zoning districts, such as smaller lot sizes, lot widths, floor area ratios and setbacks, particularly for higher density and attached housing developments.
Consider granting reductions in off-street parking on a case-by-case basis for senior housing.
Some members of the community have voiced their concern about the lack of commercial space in the proposed development. While there are some policies in the General Plan that encourage mixed-use development at the site, upon review of the project application, staff determined that this proposed project at this location in balance is consistent with the General Plan Land Use Designation of “Commercial/Residential” that allows for commercial, residential, or a mixed-use residential commercial project. the lack of retail as a substantial component being included in this mixed-use area with commercial zoning (Strategy LU-1.3.1: Commercial and Residential Uses) and as referenced in the “Neighborhood Commercial centers” concept discussed in the General Plan on page LU18 has been cited as cause for concern.
Strategy LU-1.3.1 requires the City to “review the placement of commercial and residential uses” based on certain criteria including “1. All mixed-use areas with commercial zoning will require retail as a substantial component. The North De Anza Special Areas is an exception.” In this case, the property allows residential uses in the General Plan designation; therefore, regardless of the zoning of the property, residential uses must be allowed on the site at a density allowed in the General Plan. 337

The Neighborhood Commercial centers1, identified in the Community Form Diagram in Figure LU-2 of the General Plan, include the Bateh Brothers site. The General Plan states that Residential uses in a “Neighborhood Commercial center” should be designed on the “mixed-use village concept discussed in this Element.” The “mixed-use village” concept highlights several aspects of development such as parcel assembly and discouraging parcelization, layout with an internal street grid using transect planning, uses allowed, open space requirements and architecture. However, these are permissive and not binding requirements.
The developer, upon staff’s request, considered the inclusion of a small commercial space and another with a live work unit in the development in an early preliminary proposal.
However, citing the added cost of providing underground parking, viability of the commercial space and loss of residential units of the kind that he wished to develop (attached single family units) as being deterrents to the development of his project, the developer proceeded with an application for an all residential project.
Therefore, upon review of the proposal, as required by the General Plan, based on the information from the developer, consultation with Economic Development staff and the non-mandatory, permissive language of the General Plan, it was determined that inclusion of commercial space at this site would not be required, and that in balance the proposal was in compliance with the General Plan.
Should the proposed project be approved, nine (9) units would be allocated from the neighborhood development allocation.
Development Regulations
The project site defers to the development standards of the General Plan, and Planned Development “P” zoning designation. The “P” zoning designation is detailed in Cupertino Municipal Code Chapter 19:80 Planned Development Zones. The “P” zoning designation is intended to provide a means of guiding land development or redevelopment of the City that is uniquely suited for planned coordination of land uses and land development. While in the Planned Development zoning district, development has to adhere to Multifamily (R3) zoning regulations, as an alternative, applicants can, in conjunction with a rezoning application, apply for a discretionary review of the project and propose alternative standards unique to the site. Once established, the development

* The site is located in a Planned Development (P) zoning district. Chapter 19.80 of the Municipal Code allows the establishment of specific development standards and regulations with the approval of definitive plans for a site.
The proposed project provides three (3) different unit models in four (4) separate buildings. The project has been designed to place the proposed structures closer to Stevens Creek Boulevard and South Foothill Boulevard due to the abutting single family residential uses to the south. This has allowed for setback to the closest residential properties to the rear to be between 26 feet 7 inches and 29 feet. There is a 13 to 14 foot setback proposed between the three buildings fronting Stevens Creek Boulevard and a 10-foot setback between the corner building and the building fronting S. Foothill Boulevard. There are no interior setbacks proposed for the units that are side by side.
Because the project will require significant right-of-way dedication to the City, the project incorporates smaller setbacks along the street perimeter. By providing the right-of way dedication, the project is able to incorporate a detached sidewalk, and landscape improvements along the perimeter of the property. (see Figure 2 and 3 below.) While the setback from the property line is 5’7” along Stevens Creek Boulevard and S.
Foothill Boulevard, setback from the face of curb will be 20’2” from Stevens Creek Boulevard and 26’8” from South Foothill Boulevard. Similarly, while the setback from the property line along Camino Vista Drive is 12’5”, the setback from the face of curb is 23’1”.
To accommodate different engineering standards, the project proposes a new natural grade as part of the grading plan that would establish a lower natural grade. Natural grade may be established (or reestablished, as in this case) as part of an approved grading plan that is part of a subdivision map approval. Building height will be measured from this new natural grade and will remain below the allowed maximum height of 30’. 339

The project has incorporated open space requirements for those in the Heart of the City Specific Plan. These requirements were adopted to ensure that attached multi-family units (such as those envisioned to be primarily developed in the Heart of the City Special Area) had adequate open space when considering quality of life of the new residents.
Since the proposal is for attached units, these are considered adequate for this project.
The applicant proposes open space within the project as indicated in the following table:
Heart of the City Requirements Proposed
Common Open Space 1,350 sq. ft. (150 sq. ft. per unit) 1,475 sq. ft.
Private Open Space 60 sq. ft./unit and no dimension

Site Planning and Architectural Design
The site provides vehicle access via Foothill Boulevard (to the east) and Camino Vista Drive (to the west) and, as described earlier, creates a larger physical separation from the abutting residences. All the units have access from a direct pedestrian connection to the public sidewalk and some also have an internal entrance through the garage of each unit.
The site also incorporates guest parking as required by the City’s parking ordinance.
As shown in the figure below, the project proposes common outdoor space for residents and guests at the rear of the property. Additionally, the project incorporates tree canopy throughout the perimeter of the site. At the street frontages, the applicant has worked with City staff to create a walkable frontage by providing a detached sidewalk with trees on either side. Along the rear of the property, adjacent to the single-family residences, the applicant has incorporated Saratoga Laurel trees to screen the development.

By integrating projecting and recessed wall planes, wall height variation, and roofline variation, the applicant has worked to reduce the massing of the individual buildings.
The applicant has introduced different projections along the building frontage that help to reduce the massing of the structure. The applicant has incorporated horizontal masking elements on the first floor of all units, stone materials around the first-floor walls near front doors, and additional horizontal elements added at the second floor of units along Foothill Boulevard.
Traffic, Circulation and Parking Analysis
As part of the environmental analysis, traffic impacts of the proposed projects were evaluated. These impacts were found to be less than significant because the projects would generate 1,744 fewer daily vehicle trips and 3,262 fewer daily Vehicle Miles Traveled (VMT). Additionally, the project would not generate a demand for transit that would exceed the capacity of the system. Coupled with the project being consistent with adopted policies, plans, or programs regarding pedestrian and bicycle facilities that project would have a less than significant impact.
The proposed project development has been parked to meet the City’s parking requirements found in Chapter 19.124: Parking Regulations. The nine (9) small lot singlefamily homes are parked at a parking ratio of 2.8 parking spaces per unit. Two (2) of the spaces are to be located within an enclosed garage, and 0.8 spaces may be open. This has been provided with each unit containing a two (2) car garage and eight (8) open spaces.
One of the units is providing two tandem garage spaces while the other units have two side by side parking spaces.
There is no required bicycle parking for the small lot single-family homes.
Vesting Tentative Map
The project proposes ten (10) separate parcels to be created from the three (3) existing parcels. Nine (9) lots for the proposed residential units, and one (1) common lot. A condition of approval has been added to the Tentative Map to require reciprocal access throughout the site and a formation of a property owner’s association to aid maintenance of the driveway aisle and common areas.
Below Market Rate Units
The project would provide 15% Below Market Rate (BMR) units consistent with the City’s BMR Manual when the project was submitted. To be consistent with the 15% BMR requirements, the applicant would provide one for sale. One (1) for sale unit would be provided to a median income household. The unit must be affordable for 99 years. 342

Project History
On May 7, 2020 the applicant submitted an application that was deemed complete on July 13, 2021 and evaluated in the Draft Initial Study and Mitigated Negative Declaration. The Final Draft of the Initial Study and Mitigated Negative Declaration is attached, see Attachment 7.
Housing Accountability Act
The Housing Accountability Act (HAA), California Government Code Section 65589.5(j), requires that when a proposed housing development complies with the applicable, objective general plan and zoning standards, but a local agency proposes to deny the project or approve it only if the density is reduced, the agency must base its decision on written findings supported by substantial evidence that:
1. The development would have a specific adverse impact on public health or safety unless disapproved, or approved at a lower density; and
2. There is no feasible method to satisfactorily mitigate or avoid the specific adverse impact, other than the disapproval, or approval at a lower density.
Subdivision (j) of the HAA also requires the local agency to identify and provide written documentation of the reasons why a proposed housing development is inconsistent, not in compliance, or not in conformity with an applicable plan, program, policy, ordinance, standard, requirement, or other provision within 30 days of the date that the application for the housing development project is determined to be complete if the housing development project contains 150 or fewer housing units.
The proposed project has been determined to comply with applicable, objective general plan and zoning standards, including maximum height, density, minimum setbacks, useable common and private open space, and number of parking spaces. Thus, 343

subdivision (j) of the Housing Accountability Act applies. Staff is not aware of any basis to make the findings listed above.
Environmental Review
A Draft Initial Study and Mitigated Negative Declaration (IS/MND) has been prepared for the project (See Attachment 7.) The Mitigated Negative Declaration (MND) identifies mitigation measures in the following areas, to reduce the potential environmental impacts of the project to less than significant levels:
Air Quality: Construction shall comply with BAAQMD’s recommendations for reducing construction emissions of fugitive dust and shall ensure construction emissions are reduced.
Biological Resources: The project shall protect nests of raptors and other birds when in active use.
Cultural and Tribal Resources: The project shall incorporate mitigations in the event any cultural resources or archaeological are found on site. This includes consulting with a tribal representative as well as paleontologist. Noise Levels: Construction shall comply with the Noise Ordinance and best management practices for noise mitigation, and ensure mechanical equipment selected meet the City’s noise ordinance.
Geology and Soils: The project shall incorporate mitigation in the event any fossilbearing deposits are discovered on-site. Utilities: Demonstrate to the City and Cupertino Sanitary District that the project would not exceed peak wet weather flow capacity of the Santa Clara sanitary sewer system.
As part of the environmental analysis, Staff consulted with the Tamien Nation per the regulations of Assembly Bill 52. As a result of the consultation, Staff updated to the Cultural and Tribal Resources mitigation to include tribal consultation. After the Planning Commission hearing, the Tamien Nation representative contacted the City to request that mitigation measure be modified to be specific to the Tamien Nation. This edit has been made to the Mitigated Negative Declaration and the resolutions.
The mitigation measures have been added as condition of approval for this project.
The Notice of Intent (NOI) to adopt a MND was placed in the newspaper. In addition, the NOI was mailed to notify neighbors and interested parties that a Draft MND had been prepared which the City intends to adopt. The 20-day Public Review Period for the Draft MND was between July 16, 2021 and August 5, 2021. 344

8 authorized representatives that are assigned to respond in the event of a noise or vibration complaint.
The project applicant and contractors shall prepare and submit a Construction Noise Control Plan to the City’s Building Department and Code Enforcement for review and approval prior to issuance of any grading, demolition, and/or building permits. The Construction Noise Plan shall demonstrate compliance with the 80-dBA limit in the CMC. The details of the Construction Noise Control Plan, including those details listed herein, shall be included as part of the permit application drawing set and as part of the construction drawing set, shall be implemented by the on-site Construction Manager, and shall include, but not be limited to, the following available controls to comply with the 80 dBA performance standard:
At least 10 days prior to the start of construction activities, a sign will be posted at the entrance(s) to the job site, clearly visible to the public, which includes permitted construction days and hours, as well as the telephone numbers of the City’s and contractor’s authorized representatives that are assigned to respond in the event of a noise or vibration complaint. If the authorized contractor’s representative receives a complaint, they will investigate, take appropriate corrective action, and report the action to the City.
During the entire active construction period, equipment and trucks used for project construction will utilize the best available noise control techniques (e.g., improved mufflers, equipment re-design, use of intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds), wherever feasible.
Include noise control requirements for equipment and tools, including concrete saws, to the maximum extent feasible. Such requirements could include, but are not limited to, erecting temporary plywood noise barriers between construction areas and nearby sensitive receptors; performing work in a manner that minimizes noise; and undertaking the noisiest activities during times of least disturbance to nearby sensitive receptors. During the entire active construction period, stationary noise sources will be located as far from sensitive receptors as possible, and they will be muffled and enclosed within temporary sheds, or insulation barriers or other measures will be incorporated to the extent feasible.
During the entire active construction period, noisy operations will be conducted simultaneously to the degree feasible in order to reduce the time periods of these operations.

9 Select haul routes that avoid the greatest amount of sensitive use areas and submit to the City of Cupertino Public Works Department for approval prior to the start of the construction phase.
Signs will be posted at the job site entrance(s), within the on-site construction zones, and along queueing lanes (if any) to reinforce the prohibition of unnecessary engine idling. All other equipment will be turned off if not in use for more than 5 minutes.
During the entire active construction period and to the extent feasible, the use of noise producing signals, including horns, whistles, alarms, and bells will be for safety warning purposes only. The construction manager will use smart back-up alarms, which automatically adjust the alarm level based on the background noise level or switch off back-up alarms and replace with human spotters in compliance with all safety requirements and laws.
Mitigation Measure NOISE-2: Mechanical equipment shall be selected and designed to reduce impacts on surrounding uses to meet the Cupertino Municipal Code noise limits of 60 dBA and 50 dBA at residential uses during daytime and nighttime, respectively, and 65 dBA and 55 dBA at non-residential sensitive uses during daytime and nighttime, respectively. A qualified acoustical consultant shall be retained to review mechanical noise as these systems are selected to determine specific noise reduction measures necessary to reduce noise to comply with the City’s noise level requirements. Mechanical equipment shall be selected and designed to reduce impacts on surrounding uses to meet the City’s noise level requirements. Noise reduction measures could include, but are not limited to:
Selection of equipment that emits low noise levels;
Installation of noise dampening techniques, such as enclosures and parapet walls, to block the line-of-sight between the noise source and the nearest receptors; or
Locating equipment in less noise-sensitive areas, where feasible.
Mitigation Measure NOISE-3: If paving activity during construction is required within 25 feet of nearby residential structures, the use of a static roller in lieu of a vibratory roller shall be employed. Grading and earthwork activities within 15 feet of adjacent residential structures shall be conducted with off-road equipment that is limited to 100 horsepower or less. This mitigation measure shall be identified on the permit application drawing set and as part of the construction drawing set, and shall be implemented by the on-site Construction Manager. 355

Further, the project incorporates recessing wall plans, wall height variation, and roofline variation to further reduce the height and bulk of the buildings. b) In order to preserve design harmony between new and existing building and in order to preserve and enhance property values, the materials, textures and colors of new building should harmonize with adjacent development by being consistent or compatible with design and color schemes with the future character of the neighborhoods and purposes of the zone in which they are situated. The location, height and materials of walls, fencing, hedges and screen planting should harmonize with adjacent development. Unsightly storage areas, utility installations and unsightly elements of parking lots should be concealed. The planting of ground cover or various types of pavements should be used to prevent dust and erosion, and the unnecessary destruction of existing healthy trees should be avoided.
Lighting for development should be adequate to meet safety requirements as specified by the engineering and building departments, and provide shielding to prevent spill-over light to adjoining property owners.
The design quality of the development is consistent with the high-quality standards encouraged by City Staff. The architectural style is consistent throughout the development.
Further, the planting plan provides extensive ground cover and canopy throughout the project, and provides planting screening for adjacent properties. Utility installation has been designed to be screened by landscaping and or incorporated into the building design.
The final lighting for the development will be reviewed as part of the review of the project construction documents to ensure that they meet safety requirements and ensure consistency with the City’s lighting regulations.
c) The number, location, color, size, height, lighting and landscaping of outdoor advertising signs and structures shall minimize traffic hazards and shall positively affect the general appearance of the neighborhood and harmonize with adjacent development; and
Signage approval is not included in this application.

d) With respect to new projects within existing residential neighborhoods, new development should be designed to protect residents from noise, traffic, light and visually intrusive effects by use of buffering, setbacks, landscaping, walls and other appropriate design measures.
The project abuts residential development along the west and southern property lines. The project has been designed to create a large setback from existing residences in order to reduce impacts. The rear property proposes extensive plantings areas to further buffer the project.
Additionally, the project will be required to meet the City’s noise and lighting regulation to avoid any intrusive effects.

Introduction
This document is an Initial Study for the Canyon Crossings Mixed-Use Project (proposed project) prepared by the City of Cupertino (City) to determine if the proposed project may have a significant effect on the environment. This Initial Study was prepared pursuant to the California Environmental Quality Act (CEQA) (Public Resources Code sections 21000 et seq.). Pursuant to Section 15051 of the State CEQA Guidelines,1 the City is the lead agency for the proposed project.
The project site is located on a 1.57-acre site that is proposed for redevelopment by SCR Enterprises (the project applicant). The site is located at 10625 South Foothill Boulevard, 2 where South Foothill Boulevard
meets Stevens Canyon Road. The project site is surrounded by single-family residential uses. The site is currently developed with three buildings, a surface parking lot, and associated landscaping. The proposed project would involve demolishing the existing structures and redeveloping the site with 4,536 square feet of commercial space and up to 18 residential units comprised of apartments, eight attached, and five detached single-family units. All proposed structures would have a maximum building height of 30 feet (two stories) and would include parking and associated landscaping. One level of below-grade parking garage would be located under the mixed-use building.
The project site is assigned Assessor’s Parcel Numbers 342-16-087 and 342-16-088. The General Plan land use designation for the project site is Commercial/Residential and the Zoning District is Planning Development with General Commercial (P(CG)). The Commercial/Residential land use designation allows primarily commercial uses and secondarily residential uses, or a compatible combination of the two. The proposed project includes rezoning the project site to Planning Development with General Commercial and Residential (P(CG,Res), to support the proposed residential uses intended to support commercial development. A detailed description of the proposed project is provided in Chapter 3, Project Description, of this Initial Study.
1.1 INITIAL STUDY
Pursuant to CEQA Guidelines Section 15063, an Initial Study is a preliminary environmental analysis that is used by the lead agency as a basis for determining what form of environmental review is required for a project. The CEQA Guidelines require that an Initial Study contain a project description, description of environmental setting, identification of environmental effects by checklist or other similar form, explanation of environmental effects, discussion of mitigation for significant environmental effects, 1 The CEQA Guidelines are found in California Code of Regulations, Title, 14, Section 15000 et seq. 2 There are several addresses assigned to the project site, but for the purposes of this Initial Study, a single address (10625 South Foothill Boulevard) is used to represent the entire project site. 424

evaluation of the project’s consistency with existing and applicable land use controls, and the name of persons who prepared the study.
1.2 TIERING PROCESS
The CEQA concept of "tiering" refers to the evaluation of general environmental matters in a broad program-level EIR, with subsequent focused or project-level environmental documents for individual projects that implement the program. Pursuant to CEQA Guidelines Section 15152 this Initial Study is tiered from the City’s General Plan Amendment, Housing Element Update, and associated Rezoning Project Environmental Impact Report (EIR) that was certified by the Cupertino City Council in December 2014,3 and the subsequent addenda to the EIR that were approved by the City Council in October 2015,4 August 2019,5 and December 2019,6 together hereinafter “General Plan EIR.” Pursuant to CEQA Guidelines Section 15150 this Initial Study incorporates by reference the discussions in the General Plan EIR.7 As previously stated, copies of documents referenced herein are available for review at the City of Cupertino Community Development Department at 10300 Torre Avenue, Cupertino, California 95014.
The analysis in this Initial Study concentrates on the project-specific issues pertaining to the proposed Canyon Crossings Mixed-Use project. CEQA and the CEQA Guidelines encourage the use of tiered environmental documents to reduce delays and excessive paperwork in the environmental review process. This is accomplished in tiered documents by eliminating repetitive analyses of issues that were adequately addressed in the program EIRs and by incorporating those analyses by reference.
In order to determine whether the proposed project was part of the development that was examined in the General Plan EIR, the following questions must be answered:
Is the proposed project included in the scope of the development projected and analyzed in the General Plan EIR?
Is the project site in an area designated for Commercial/Residential land uses in the General Plan and Planned Development with General Commercial and Residential Zoning District? Are the changes to population and employment associated with the proposed project included within the scope of the projections accounted for in the General Plan EIR? Is the proposed project within the scope of the cumulative analysis in the General Plan EIR? The General Plan EIR included an evaluation of the project site as potential Housing Element Site 9 (Foothill at McClellan Center – Foothill Market), although the adopted General Plan did not designate this 3 City of Cupertino, certified General Plan Amendment, Housing Element Update, and Associated Rezoning EIR, State Clearinghouse Number 2014032007.

site as a Priority Housing Element Site. The evaluation in the General Plan EIR assumed potential redevelopment of commercial and residential uses with 27 maximum dwelling units and a maximum building height of 30 feet. The General Plan EIR evaluated a Zoning District change from Planned Development with General Commercial (P(CG)) to Planned Development with General Commercial and Residential (P(CG,Res)) to accommodate the construction of residential uses on-site. The project is consistent with the General Plan land use designation, but because the City Council did not identify this as a Housing Element site, the Zoning Map was not amended following the certification of the General Plan EIR. The approval of the proposed project would require an amendment to the Zoning Map to allow residential uses on the project site as proposed. The cumulative impacts of past, present, and probable future development, in conjunction with overall General Plan buildout, including residential development of the project site, were evaluated in the General Plan EIR. Accordingly, this Initial Study tiers from the General Plan EIR pursuant to CEQA Guidelines Section 15152 (Public Resources Code Section 21094).
Table 1-1 identifies the development potential that was analyzed for the project site in the General Plan EIR, what type of development the General Plan currently anticipates for the project site, and what is proposed for the site as part of the project.

REVISED FINAL DRAFT
City received a request to be notified about projects in the city of Cupertino from the Tamien Nation on May 28, 2021, as the city is within the geographic area with which they are traditionally and culturally affiliated. The request was received following the release of the Public Review Draft IS/MND in March 2021. The City conducted the consultation process with the Tamien Nation and changes to Mitigation Measure CULT-1 were reflected in the Final IS/MND in October 2021. This Revised Final IS/MND reflects additional text changes to Mitigation Measure CULT-1 requested by the Tamien Nation after the preparation of the Final IS/MND. These changes do not constitute a substantial revision as defined in CEQA Guidelines Section 15073.5; therefore, the IS/MND does not need to be recirculated.
2.2 ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED
The environmental factors checked below would be potentially affected by the proposed project, involving at least one impact that is a potentially significant impact, as shown in Chapter 4, Environmental Analysis, of this Initial Study.

Geology & Soils Greenhouse Gas Emissions Hazards & Hazardous Materials Hydrology & Water Quality Land Use & Planning Mineral Resources Noise Population & Housing Public Services
Recreation Transportation Tribal Cultural Resources
Utilities & Service Systems Wildfire Mandatory Findings of Significance
2.3 DETERMINATION
On the basis of this initial evaluation:
I find that the proposed project COULD NOT have a significant effect on the environment and a NEGATIVE DECLARATION will be prepared.
I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.
I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.
I find that the proposed project MAY have a “potentially significant impact” or “potentially significant unless mitigated” impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. 429

2.4 SUMMARY OF IMPACTS AND MITIGATION MEASURES
Due to the location of the project site, the proposed project would have no impact on Agriculture, Forestry, or Mineral Resources; therefore, these topics are not discussed in detail in the Initial Study. The following lists the potentially significant impacts by topic that could occur from construction and operation of the proposed project and identifies mitigation measures to reduce the impacts to a lessthan-significant level. All other topic areas were identified to have less-than-significant impacts. A detailed discussion of the project’s impacts is provided in Chapter 4, Environmental Analysis, of this Initial Study.
AIR QUALITY
Impact AQ-1: Fugitive dust (PM10 and PM2.5) generated by the proposed project during construction could potentially result in significant regional short-term air quality impacts without implementation of the Bay Area Air Quality Management District’s best management practices related to reducing fugitive dust emissions.
Mitigation Measure AQ-1: The project’s construction contractor shall comply with the following best management practices for reducing construction emissions of fugitive dust (PM10 and PM2.5) as required by the Bay Area Air Quality Management District Revised California Environmental Quality Act Air Quality Guidelines:
Water all active construction areas at least twice daily, or as often as needed to control dust emissions. Watering should be sufficient to prevent airborne dust from leaving the site. Increased watering frequency may be necessary whenever wind speeds exceed 15 miles per hour. Reclaimed water should be used whenever possible.
Pave, apply water twice daily or as often as necessary to control dust, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites. Cover all trucks hauling soil, sand, and other loose materials. Sweep daily (with water sweepers using reclaimed water if possible) or as often as needed all paved access roads, parking areas and staging areas at the construction site to control dust. Sweep public streets daily (with water sweepers using reclaimed water if possible) in the vicinity of the project site, or as often as needed, to keep streets free of visible soil material. 430

EXECUTIVE SUMMARY
2-4 DECEMBER 2021
REVISED FINAL DRAFT
Hydroseed or apply non-toxic soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply non-toxic soil binders to exposed stockpiles (dirt/sand). Limit vehicle traffic speeds on unpaved roads to 15 miles per hour. Replant vegetation in disturbed areas as quickly as possible and water appropriately until vegetation is established.
Install sandbags or other erosion control measures to prevent silt runoff from public roadways. All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe.
Impact AQ-2: The proposed project could expose sensitive receptors to substantial pollutant concentrations during construction.
Mitigation Measure AQ-2: During construction, the construction contractor(s) shall:
Use construction equipment that have engines that meet either the United States Environmental Protection Agency (USEPA) or California Air Resources Board (CARB) Tier 4 Interim emissions standards for off-road diesel-powered construction equipment with more than 50 horsepower, unless it can be demonstrated to the City of Cupertino Building Division that such equipment is not available.
Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by Tier 4 Interim emissions standards for a similarly sized engine, as defined by the CARB’s regulations.

Project Description
The project applicant, SCR Enterprises, is proposing the Canyon Crossings Mixed-Use Project (proposed project) that would involve the construction of a commercial and residential development on a 1.57-acre site. The site is currently developed with three buildings, a surface parking lot, and associated landscaping. The largest building on the project site is a multi-tenant commercial building on the southwestern portion of the site. A smaller commercial building, with an attached, unoccupied residential unit that is used for storage, is on the northeast portion of the site. In addition, a detached and unoccupied single-family residential unit is on the northwest portion of the project site. The proposed project would involve demolishing all the existing structures and redeveloping the site with a mixed-use building including 4,536 square feet of neighborhood-serving commercial space and five apartments, as well as a mix of 13 attached and detached single-family units, for a combined total of 18 residential units.
All proposed structures would have a maximum building height of 30 feet (two stories). All parking would be at the ground level except for a single-level subterranean parking garage located under the mixed-use building.
This chapter provides a detailed description of the proposed project, including the location, setting, and characteristics of the project site, the principal project features, construction phasing and schedule, as well as a list of the required permits and approvals.
3.1 PROJECT LOCATION AND SITE CHARACTERISTICS

REVISED FINAL DRAFT
The site was used for orchards and associated buildings in 1939. The orchards were removed in 1948.
According to the Department of Toxic Substance Control, when orchards have been removed or became inactive prior to 1950 organic pesticides are not an issue warranting further testing.9 Following the removal of the orchards, the project site was developed with the existing smaller mixed-use building located on the site. The larger building on the site was constructed by 1963.10 Due to the age of the existing buildings, they may contain asbestos-containing materials or lead-based paint, which were not regulated in construction until the early 1970’s.
Because the smaller building on the project site was developed in 1948, it has the potential to be considered a historic building; however, it is not currently listed on the National Register of Historic Places or the list of California Historical resources.11
Surrounding uses in the vicinity of the project site include one-story and two-story single-family residential units.
VEGETATION AND LANDCOVER
Using data from the Classification and Assessment with Landsat of Visible Ecological Groupings (CALVEG)12 habitat mapping program, the site is classified as an “urban area.” Property with this classification tends to have low to poor wildlife habitat value due to replacement of natural communities, fragmentation of remaining open space areas and parks, and intensive human disturbance. According to the Vegetation Map shown in the Environmental Resources and Sustainability Element of the General Plan, the project site is within the urban forest (i.e., trees in the city). 13 The City recognizes that every tree on both public
and private property is an important part of Cupertino's urban forest and contributes significant economic, environmental, and aesthetic benefits of the community.14 Landscaping on-site includes two mature and non-native trees over 70 feet tall, a Redwood tree on the northeast corner that is proposed for removal, and a Palm tree on the southeast corner that would remain. The trees on-site are considered protected development trees pursuant to Cupertino Municipal Code (CMC) Section 14.18.050(c).

The California Natural Diversity Database (CNDDB) has no record of special-status plant or animal species on the project site but does show there are special-status plant and animal species within a 5-mile area surrounding the project site. Special-status species have been recorded in the open space areas in the project vicinity.
The California Department of Forestry and Fire Projection (CAL FIRE) has designated the project site as a Local Responsibility Area (LRA) and a non-very high fire hazard severity zone. The project site is near lands that CAL FIRE designates as a State Responsibility Area (SRA), which are approximately 0.5 miles to the west of the site.16 The project site is located within the wildland-urban interface, which is an area of transition between wildland (unoccupied land) and land with human development (occupied land). 17 The site is generally flat with elevation of 429 feet above mean sea level with a regional topographic slope downward to the east.18 The surficial geology is young, unconsolidated Quaternary alluvium,19 which is described as Holocene-age younger alluvium and coarse-grained alluvium that are composed of unconsolidated, poorly sorted gravel, silt, sand, clay, and organic matter. No paleontological resources have been identified on the project site; however, the presence of Pleistocene deposits that are known to contain fossils indicates that the overall city, including the project site, could contain paleontological resources.20
The existing impervious surface totals 46,584 square feet. Stormwater from the site drains to a network of City-maintained storm drains in Stevens Canyon Road and South Foothill Boulevard that collect runoff from city streets and carry it to the creeks that run through Cupertino to the San Francisco Bay. The project site is within an area where some of the storm drains are deficient in conveying the water from a 10-year storm, based on the 2018 Storm Drain Master Plan. 16 CAL FIRE. 2008.

3.1.4 LAND USE DESIGNATION AND ZONING
GENERAL PLAN
The site is located in the Other Non-Residential/Mixed-Use Special Area21 and a Neighborhood Center. 22 The site is located in the Inspiration Heights Neighborhood abutting the Monta Vista North Neighborhood.
23 The site has a General Plan land use designation of Commercial/ Residential.24 A description of these designations is provided below.
Other Non-Residential/Mixed-Use Special Areas
The City has designated Special Areas along one of the four major mixed-use corridors in the city, which represent key areas within Cupertino where future development and reinvestment is generally focused.
The Other Non-Residential/Mixed-Use Special Area include four key areas and all other nonresidential properties not referenced in an identified commercial area. The project site is at one of the four key areas identified as the west side of Stevens Canyon Road. 25 The Other Non-Residential/Mixed-Use Special Area describes the vision for Neighborhood Centers and states that such locations should be redeveloped using the “Neighborhood Commercial Center” concept described in the Land Use and Community Design Element of the General Plan (Chapter 2).26 However, developing using this concept is not required. The vision statement describes that buildings in the Neighborhood Centers should be typically one to two stories tall but may be up to three stories in some instances where it is allowed.27 The maximum residential density within Neighborhood Commercial Centers identified in the Community Form Diagram is 15 dwelling units per acre.28
Inspiration Heights Neighborhood
Cupertino has 12 distinct neighborhoods that are each unique in their location, development pattern, identity, and access to community services. While the Inspiration Heights neighborhood is situated in the western foothills of Cupertino, the project site is located in the lower elevation portions of the neighborhood that is urbanized. The project site is on the western border of this neighborhood on Stevens Creek and Foothill Boulevards, which provides a transition with the adjoining neighborhoods on the valley floor. The vision for this neighborhood, as described in the General Plan, is to continue to be a 21 City of Cupertino General Plan (Community Vision 2015-2040), Chapter 2, Planning Areas, page PA-15. 22 City of Cupertino General Plan (Community Vision 2015-2040), Chapter 3, Land Use and Community Design Element, Figure LU-2, Community Form Diagram, page LU-17. 23 City of Cupertino General Plan (Community Vision 2015-2040), Chapter 2, Planning Areas, Figure PA-2, Neighborhoods, page PA-18. 24 City of Cupertino Land Use Map adopted November 15, 2005 and amended August 20, 2019. 25 City of Cupertino General Plan (Community Vision 2015-2040), Chapter 3, Land Use and Community Design Element, page LU-65.

low-intensity and hillside residential area.
29 Future development should consider preservation of hillsides, riparian corridors, and plant and animal wildlife habitat through sensitive site and building design.30 Commercial/Residential Land Use Designation
The Commercial/Residential land use designation allows primarily commercial uses and secondarily residential uses or a compatible combination of the two uses. 31 Commercial use means retail sales,
businesses, limited professional offices, and service establishments with direct contact with customers.
This land use designation applies to commercial activities ranging from neighborhood convenience stores to regionally oriented specialty stores. Retail stores that would be a nuisance for adjoining neighborhoods or harmful to the community identity would be regulated by CMC Chapter 19.60, General Commercial Zones, and the associated commercial zoning ordinance use permit procedures. Smaller commercial parcels in existing residential areas, such as the project site, may be needed to provide local neighborhood serving retail; otherwise, they may be redeveloped at residential densities compatible with the surroundings. As previously stated, the maximum residential density on the project site is 15 dwelling units per acre.32
ZONING DISTRICT
The project site is within the Planned Development with General Commercial (P(CG)) zoning district. As described in CMC Section 19.80.010, the Planned Development zoning district is intended to provide a means of guiding land development or redevelopment of the city that is uniquely suited for planned coordination of land uses. Development in this zoning district provides for a greater flexibility of land use intensity and design because of accessibility, ownership patterns, topographical considerations, and community design objectives.33 CMC Chapter 19.80 also allows a project proponent to propose development standards for their specific project.
All Planned Development districts are identified on the zoning map with the letter coding "P" followed by a specific reference to the general type of use allowed in the particular planning development zoning district. The type of use allowed on the project site is General Commercial (CG), which allows commercial uses such as retail food, drug, apparel, or hardware stores, full-service restaurants, professional and commercial office services, laundry facilities, non-auto related repair services, and personal services, along with several other specialty uses.

PROJECT DESCRIPTION
3-10 DECEMBER 2021
REVISED FINAL DRAFT
The proposed designation of General Commercial with Residential uses (CG, Res), which is consistent with the General Plan land use designation for the site, is a district in which uses are intended to be a mix of general commercial and residential.35 The proposed project requires a zoning amendment to allow residential uses on the project site. This is discussed further, below, in Section 3.2, Project Components.
OTHER REQUIREMENTS
Setback Standards
Because the property is zoned Planned Development, any proposed commercial project would have to meet the specific front, side, or rear yard setbacks required when a lot abuts residential or agricultural zones based on CMC Chapter 19.64, General Commercial (CG) zoning district. However, in the event, the commercial property does not abut these zones, there are no stated setbacks, in which case, setback requirements for commercial property would be determined by City staff during project review.
The proposed project is a mixed-use single-family development on a small lot (1.57 acres). The City’s Zoning Code does not have any adopted standards for the development of projects similar to the proposed project. However, pursuant to CMC Chapter 19.80, the Planned Development Zoning District allows a project proponent to propose zoning setbacks different from those required in the underlying Zoning District to allow flexibility in the project, as long as these are approved by the City Council. In any case, the setbacks in the Zoning Code or the setbacks proposed by the project, the project site must adhere to the General Plan requirement of maintaining sufficient space for adequate light, requirement for air and visibility at intersections, and the requirement for general conformity to yard requirements of adjacent or nearby zones, lot or parcels. The General Plan does not have any applicable setback requirements for this property.
Landscaping
CMC Chapter 14.15, Landscape Ordinance, implements the California Water Conservation in Landscaping Act of 2006 by establishing new water-efficient landscaping and irrigation requirements. Any building or landscape project that involves more than 2,500 square feet of landscape area is required to submit a Landscape Project Submittal to the Director of Community Development for approval. Existing and established landscaped areas greater than 1 acre in size, including cemeteries, are required to submit water budget calculations and audits of established landscapes.36 Tree Requirements
CMC Chapter 14.12, Trees, establishes regulations for the planting, care, and maintenance of public trees, and provides for the continuous maintenance of the public trees, with the goal of encouraging 35 City of Cupertino Municipal Code, Title 19, Zoning, Chapter 19.80, Planned Development, Section 19.80.030, Establishment of Districts- Permitted and Conditional Uses. 36 City of Cupertino Municipal Code, Title 14, Streets, Sidewalks and Landscaping, Chapter 14.15, Landscape Ordinance. 447

preservation of trees. The City funds the planting and maintenance of public trees through payment of reimbursement costs as a conditions of building permit issuance.37 CMC Chapter 14.18, Protected Tree Ordinance, provides regulations for the protection, preservation, and maintenance of trees of certain species and sizes.38 Removal of a protected tree requires a permit from the City. “Protected” trees include trees of a certain species and size on private property in all zoning districts; heritage trees whether on private or public property in all zoning districts; any tree required to be planted or retained as part of an approved development application, building permit, tree removal permit, or code enforcement action in all zoning districts; and approved privacy protection planting in single-family residential (R-1) zoning districts. Since the existing development is on property that requires a development application, all existing trees on the site are considered protected.39 Bird Safe Design Ordinance
The City of Cupertino draft Bird Safe Design Ordinance, CMC Chapter 19.102, Glazing and Lighting Standards, which contains specific building and site design measures to reduce bird mortality from windows or other specific glass features known to increase the risk of bird collisions and to reduce light pollution known to contribute to bird mortality and reduced visibility of the night sky. These guidelines, once adopted, would be applicable to any project that is required to obtain a building permit or a Permit pursuant to Title 19, Zoning, including the proposed project.
CMC Section 19.102.030, Bird-safe Development Requirements, includes:
Glass requirements for new or replacement windows of twelve square feet or more and facades requiring no more than 10 percent of the surface area of the façade be untreated glass between the ground and 60 feet above ground. Treatments can include opaque glass, window muntins, exterior insect screens, exterior netting, or special glass treatments such as fritting to provide visual cues and reduce the likelihood of bird collisions.
Indoor lighting requirements to program automatic sensors and timer to turn off at 11:00 p.m., within two hours after business closes, or the addition of filtering with the use of interior or exterior blinds. Design requirements to avoid funneling of flight paths along buildings or trees to building facades; avoid use of highly reflective glass or highly transparent glass; and avoid glass skyways or walkways, freestanding glass walls, transparent building corners, or other design elements where trees, landscaping, water features, or the sky is visible form the exterior.
CMC Section 19.102.140, Outdoor Lighting Requirements, includes requirements to reduce light pollution throughout the city. These requirements prohibit outdoor lighting that blinks, flashes, or rotates; outdoor lighting that projects above the horizontal plan; lighting that unnecessarily illuminates other lots or interferes with the enjoyment of that lot; high-intensity discharge lighting for recreation courts or private property; and spotlights. Outdoor lighting that is not prohibited, must abide by the following:
37 City of Cupertino Municipal Code, Title 14, Streets, Sidewalks and Landscaping, Chapter 14.12, Trees. 38 City of Cupertino Municipal Code, Title 14, Streets, Sidewalks and Landscaping, Chapter 14.18, Protected Trees. 39 City of Cupertino Municipal Code, Title 14, Streets, Sidewalks and Landscaping, Chapter 14.18, Protected Trees. 448

UTILITIES AND ENERGY
Energy Conservation
The California Green Building Standards Code (Part 11, Title 24, known as “CALGreen”) was adopted as part of the California Building Standards Code (Title 24, California Code of Regulations) to apply to the planning, design, operation, construction, use, and occupancy of every newly constructed building or structure, unless otherwise indicated in the California Building Standards Code, throughout the State of California.40 CALGreen established planning and design standards for sustainable site development, energy efficiency (in excess of the California Energy Code requirements), water conservation requiring new buildings to reduce water consumption by 20 percent, material conservation, and internal air contaminants. The local building permit process enforces the building efficiency standards. CMC Chapter
16.58, Green Building Standards Code, adopts the CALGreen requirements and makes it part of the CMC along with local amendments for projects in the city. The City’s Green Building Ordinance contains mandatory, minimum required green building techniques, including measures affecting water use efficiency and water conservation.
CMC Sections 16.58.100 through 16.58.220 sets forth the standards for green building requirements by type of building. As shown on Table 101.10 in CMC Section 16.58.220, mixed-use project with residential and non-residential components shall comply by either: (1) meeting the applicable requirements for each use; or (2) meeting the applicable requirements for the use that comprises the majority of the project’s square footage where uses are attached and/or combined in a building. For the residential component, new construction greater than nine homes is required to be Green Points Rated certified at minimum 50 points, Silver in Leadership in Energy & Environmental Design (LEED), or Alternate Reference Standard per Section 101.10.2.
41 For the non-residential component, development less than 25,000 square-feet is 40 California Code of Regulations, Title 24, Part 11, January 1, 2020, California Green Buildings Standards Code, https://codes.iccsafe.org/content/CAGBSC2019/copyright. 41 Leadership in Energy & Environmental Design (LEED) is a green building certification program that recognizes best-in-class building strategies and practices that reduce consumption energy, and water, and reduce solid waste directly diverted to landfills. LEED certified buildings are ranked in order of efficiency from Certified, Silver, Gold and Platinum being the highest 449

required to comply with the CALGreen Building Code per Chapter 5 of the California Green Building Standards Code. CMC Section 16.58.230 permits applicants to apply an alternate green building standard for a project in lieu of the minimum standards outlined in CMC Section 16.58.220 that meet the same intent of conserving resources and reducing solid waste.
The California Energy Code (Part 6, Title 24) was adopted as part of the California Building Standards Code (Title 24) to reduce wasteful and unnecessary energy consumption in newly constructed and existing buildings. The City of Cupertino has adopted the California Energy Code, with local amendments into, as CMC Chapter 16.54, Energy Code. CMC Section 16.54.100(2), Scope for Newly Construction Building, requires all newly constructed buildings to be All-Electric Buildings. All-Electric Buildings are defined as a building that has no natural gas or propane plumbing installed within the building, and that uses electricity as the sole source of energy for its space heating, water heating.42 The City is currently in the process of approving reach codes, which will go above California Energy Code requirements to reduce energy and water, and associated greenhouse gas emissions.
Solid Waste Reduction
Consistent with CALGreen, CMC Chapter 16.72, Recycling and Division of Construction and Demolition Waste, requires that a minimum of 65 percent of all non-hazardous construction and demolition debris must be recycled or salvaged and that all applicants have a waste management plan for on-site sorting of construction debris. Additionally, in December 2017, the City adopted a Zero Waste Policy.43 According to the Zero Waste Policy, the City will require, through the City’s waste hauling franchise agreement, steadfast and ongoing efforts by the City’s franchisee to maintain a minimum residential and commercial waste diversion rate of 75 percent with a goal of reaching and maintaining 80 percent by 2025.
Water Quality
CMC Chapter 9.18, Storm Water Pollution Prevention and Watershed Protection provides regulations and gives legal effect to the Municipal Regional Storm Water National Pollutant Discharge Elimination System (NPDES) Permit (MRP) issued to the City. This chapter also ensures ongoing compliance with the most recent version of the City’s MRP regarding municipal storm water and urban runoff requirements. This chapter applies to all water entering the storm drain system generated on any private, public, developed, and undeveloped lands within the city. The CMC contains permit requirements for construction projects and new development or redevelopment projects to minimize the discharge of storm water runoff. ranking with the greatest efficiency standard. LEED Silver certified buildings typically reduce is the third highest ranking out of the four, with just being certified being the lowest and Gold and Platinum being the second highest. 42 CMC Section 16.54.110, Definitions and Rules of Construction. 43 City of Cupertino, Public Works, Garbage & Recycling, https://www.cupertino.org/our-city/departments/environmentsustainability/waste, accessed November 30, 2018. 450

The project applicant proposes to redevelop the project site with a mixed-use commercial and residential development consisting of one mixed-use building with commercial and residential uses and a mix of residential buildings with associated amenities, infrastructure, and landscaping. Combined the project would have 18 residential units and 4,536 square feet of neighborhood-serving commercial space. The conceptual site plan for the proposed project is shown on Figure 3-4. The following provides a detailed description of the key project components. A complete set of preliminary site plans are available on the City’s website at www.cupertino.org/canyoncrossing and at the City of Cupertino Community Development Department at 10300 Torre Avenue, Cupertino, California 95014.
3.2.1 PROPOSED BUILDINGS
MIXED-USE BUILDING
The proposed project’s mixed-use building would have 4,536 square feet of neighborhood-serving commercial space on the ground floor and five apartment units on the second floor. Apartments would be comprised of two one-bedroom units between 918 square feet and 1,003 square feet, and three twobedroom units ranging between 1,240 square feet and 1,500 square feet. The mixed-use building would front South Foothill Boulevard/ Stevens Canyon Road. See Figures 3-5 through 3-6.
A trash and recycling enclosure would be located on the ground floor on the southern side of the mixeduse building and would be accessed by the waste management company on trash day from the internal roadway network. See Figure 3-4.
One-level of subterranean parking would be provided below the mixed-use building and surface parking spaces would be provided on the northeast corner of the site. Vehicular parking would meet the standards of the Americans with Disabilities Act (ADA). Class 2 bicycle racks44 would be included at the ground level and Class 1 bicycle lockers45 would be provided for residents in the subterranean parking area. See Figure 3-7. The surface parking spaces are illustrated on Figure 3-4.
As shown in Figure 3-8, the proposed mixed-use building would be a maximum of 30 feet tall (two stories).

REVISED FINAL DRAFT
SINGLE-FAMILY RESIDENTIAL BUILDINGS
The proposed project would include a mix of attached and detached single-family residential buildings with a total of 13 single-family dwelling units. Each single-family dwelling unit would have a private driveway with an attached two-car garage that would front the internal roadway network and would be separated from the adjacent residential properties with back- and side-yard areas. The five detached single-family homes would have three bedrooms. The single-family homes are identified as numbers six through ten on Figure 3-4. The units range between 2,624 square feet and 2,642 square feet with floor area ratios between 1.11 and 1.15. The eight attached single-family homes would have three bedrooms each. The attached single-family homes are identified as numbers one through five and 11 through 13 on Figure 3-4. Two of these units are smaller at about 2,065 square feet, while the rest range between 2,481 square feet and 2,692 square feet in size. The proposed residential buildings would be a maximum of 30 feet tall (two stories). Figures 3-9 through 3-11 illustrate the elevations of each unit type.
RESIDENT AND PUBLIC AMENITIES
Each residential building would have its own private open space at the back of each unit. The backyards range in size from 264 square feet to 591 square feet in area. Each apartment unit includes a private deck that ranges from 61 square feet to 126 square feet. The proposed project also includes three common open space areas totaling 5,691 square feet. The common open space areas are labeled as Areas 1, 2, and Public Plaza on Figure 3-4. Area 1 is located on the southeastern corner of the site and is 1,044 square feet. Area 2 is located west of the mixed-use building near the center of the site and is 1,990 square feet.
Area 3 is a public plaza to the north of the mixed-use building and is 2,657 square feet. The common open space areas and the public plaza would include landscaping and areas for gathering (i.e., tables, umbrellas, benches, etc.).
3.2.2 POPULATION AND EMPLOYEE ESTIMATES
Based on an average household size of 2.87 persons,47 the proposed project would generate 52 residents.48 Applying the generation rate of one job for every 450 square feet of commercial uses, the proposed project would generate 10 employees.49 The single residential unit on site is not occupied at this time and the approximately 10,500 square feet of commercial buildings are partially occupied. Applying the same generation rates as the proposed project, the current uses at full occupancy could generate about 3 residents and 23 employees. Therefore, the net new occupants of the site would be 49 residents and minus 13 employees. It is anticipated that future residents and employees would be drawn largely from Cupertino and other communities in the San Francisco Bay Area.
47 This analysis is based on the Association of Bay Area Governments (ABAG) 2019 projections of the average household size of 2.87 persons for Cupertino in 2020. This is the standard approach for population and housing analysis in Cupertino. 48 18 new units multiplied by 2.87 persons per unit equals 51.66 new residents. 49 4,356 square feet of commercial land use/450 square feet per employee = 9.68 employees. 457

REVISED FINAL DRAFT
3.2.3 CIRCULATION AND ACCESS
VEHICULAR ACCESS
As shown on Figure 3-12, the project would have two-lane entrance/exit circulation pattern with the access points at the South Foothill Boulevard/McClellan Road intersection and the Stevens Canyon Road/ St. Andrews Avenue intersection. The project access points would modify the existing three-way (or “t”) intersections at South Foothill Boulevard/McClellan Road and Stevens Canyon Road/St. Andrews Avenue.
The proposed project would extend McClellan Road and St. Andrews Avenue onto the project site; however, the on-site roadway extensions would be for use by future residents and customers only and would be privately maintained (i.e., not the responsibility of the City). The proposed attached single-family homes would be accessed via these roadway extensions, which would allow for two-way travel in and out of the single-family homes. The proposed single-family homes would be accessed via either driveway that would run along a north-south axis on the property. Entry to the subterranean parking under the mixeduse building would be accessed from the proposed on-site roadway.
Proposed emergency access routes are similar to the proposed vehicle access routes. Emergency personnel would also have access to the backyard areas of the residential buildings via gates or partitioned fences on the side yards or backyard of the residential buildings, that would remain unlocked.
Waste management vehicles would follow the same vehicle route, with access to the two residential roads on the west side of the project site.
PEDESTRIAN AND BICYCLE ACCESS
Class II bike lanes currently exist on both sides of South Foothill Boulevard and Stevens Canyon Road along the length of the project site. Bicyclists would access the project site from the existing Class II bike lanes via the internal roadway network. Class III Bikeway or Bike Route designated signs and pavement markings for automobile and bicycle shared use are provided along McClellan Road on both sides of the roadway. 50 Pedestrian access to the site would be via the proposed monolithic sidewalk along the eastern border of the project site along the west side of South Foothill Boulevard and Stevens Canyon Road, which would connect with the internal sidewalks on the project site. The proposed sidewalk would also connect to the existing sidewalk to the north of the project site on west side of South Foothill Boulevard. Pedestrians would also have access to the site via the existing crosswalks marked with ladder stripping on Stevens Canyon Road connecting to McClellan Road and St. Andrews Avenue.
50 Class II Bikeways are bike lanes for bicyclists that are generally adjacent to the outer vehicle travel lanes and have special lane markings, pavement legends, and signage. Class III Bike Routes are designated roadways for bicycle use by signs or other markings may or may not include additional pavement width for cyclists 461

PROJECT DESCRIPTION
3-26 DECEMBER 2021
REVISED FINAL DRAFT
3.2.4 LANDSCAPING
The proposed project would include 16,602 square feet of pervious landscaped surfaces. Figure 3-13 illustrates the proposed landscaping plan. The project site includes landscaping throughout the project site’s interior and the surrounding perimeter, and additional landscaping in the common open space areas. For neighborhood privacy and to help reduce bird collisions, 5-foot screening shrubs would be planted along the north, south, and western borders of the project site, where the adjacent land use is residential. Trees and other landscaping would be planted along South Foothill Boulevard and Stevens Canyon Road as well as along the internal project roadway network. As stated above in Section 3.1.4, Land Use and Zoning, the project is required to submit a Landscape Project Submittal for approval by the City.
The proposed landscaping would be consistent with the surrounding Northern California landscape and would include native and/or adaptive, and drought resistant plant materials of similar water use grouped by hydrozones, which are areas where plants are organized based on similar water use.51 The majority of plantings would be drought tolerant grasses, shrubs, and trees that, once established, are adapted to a dry summer and intermittent rain in the winter season. There would also be appropriate landscaping in the bioretention areas required by the City’s Municipal Regional Permit.
3.2.5 LIGHT AND GLARE
As shown in by Figure 3-14, the source, intensity, and type of exterior lighting for the project site would generally be provided for the purpose of orienting site users and for safety needs. All permanent on-site lighting would be low-level illumination, downward directed, and shielded to reduce light spill or glare into surrounding residential homes. There would be no up-lighting on the mixed-use building exterior. In landscaped and paved areas, light sources would be concealed and not visible from a public viewpoint.
Unless used for safety, all outside lighting would be turned off by 11:00 p.m. All exterior surface and above-ground mounted fixtures would be complementary to the architectural theme and to the surrounding residential units.
The proposed project would not include reflective glass. Where glass features such as windows and doors are proposed, glazing treatments would vary; however, none of the exterior glass would have a light reflectance value of more than 15 percent.52
51 The California Model Water Efficient Landscape Ordinance defines a hydrozone as a portion of the landscaped area having plants with similar water needs. 52A light reflectance value or LRV is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. LRV is expressed as a percentage from 0 to 100; the higher the number the more visible light that is reflected. 463

PROJECT DESCRIPTION
PLACEWORKS 3-29
REVISED FINAL DRAFT
The HVAC system would be shielded from view by a parapet facing Stevens Canyon Road (see Figure 3-8) at least 3 feet in height, which would also serve as a noise attenuation feature. The proposed project would not include reflective glass. Where glass features are proposed, glazing treatments would vary, and none of the exterior glass would have a light reflectance value of more than 15 percent.53 The first floor of the mixed-use building and the second-floor apartments, including balcony railing elements, could have a combination of UV coatings, frosting, and fritting, which reduces glare and makes the glass visible to birds to reduce collisions.
3.2.6 UTILITIES AND ENERGY
The proposed utility infrastructure would connect to the existing water, sewer, storm drain system, natural gas and electricity network in the area, and would be served by an existing solid waste landfill.
WATER SUPPLY AND CONSERVATION
To support the proposed project, a new water line would be installed along the new main internal road to connect to the existing water lines along Stevens Canyon Road. Any new connections or replaced water lines would not encroach on undisturbed areas. All landscape zones would be irrigated as required by the Cupertino Landscape Ordinance, and water uses would be tailored to meet CALGreen Building Standards, which as described above in Section 3.1.4.2, Zoning, requires water conservation and requires new buildings to reduce water consumption by 20 percent.
SANITARY SEWER SERVICE
As shown on Figure 3-15, connections to the existing sanitary sewer system would be made on South Foothill Boulevard and Stevens Canyon Road.
STORMWATER MANAGEMENT
The proposed project would result in 43,419 square feet of impervious surfaces coverage. Compared to 47,975 square feet of impervious coverage in existing conditions, this would be a decrease of 4,556 square feet or 9 percent. The proposed project would include 16,602 square feet of pervious surfaces in the form of landscaping and two on-site bioretention facilities (1,540 square feet) that would hold and treat stormwater before it is released into the City’s off-site storm drain infrastructure). As a result, the proposed project would result in a decrease in the amount of runoff from the project site. The project is required to comply with the Santa Clara Valley Urban Runoff Pollution Prevention Program C.3 requirements, which include minimization of impervious surfaces, measures to detain or infiltrate runoff from peak flows to match pre-development conditions, and agreements to ensure that the stormwater treatment and flow control facilities are maintained in perpetuity. The project also must comply with CMC Chapter 9.18 described above in Section 3.1.4.2, Zoning, which is intended to provide regulations and give legal effect to certain requirements of the NPDES permit issued to the City. 53A light reflectance value or LRV is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. LRV is expressed as a percentage from 0 to 100; the higher the number the more visible light that is reflected. 466

SOLID WASTE SERVICES
Recology South Bay (Recology) would provide curbside recycling, garbage, and compost and landscaping waste service to the project.
54 All non-hazardous solid waste collected under the Recology franchise agreement is taken to Newby Island Sanitary Landfill for processing. Under the agreement between the City and Recology, Recology also handles recyclable materials (at no cost to customers). The proposed waste management for the proposed project would focus on waste, recycling, and composting.
OTHER UTILITIES (GAS, ELECTRIC, AND CABLE)
Pacific Gas & Electric (PG&E) would supply natural gas and electricity infrastructure to the project site. 55 The source of electricity would be provided through a partnership of Silicon Valley Clean Energy (SVCE), which provides a standard electricity offering from a 50 percent renewable portfolio,56 and PG&E. SVCE also offers a 100 percent renewable option that electricity customers can opt into. The proposed development would achieve LEED Silver, or equivalent Alternative Reference Standard, consistent with the City’s requirements.57 Telephone service would be provided by AT&T and other providers. Cable television service would be available from a number of providers, including Comcast.
3.2.7 DEMOLITION, SITE PREPARATION, AND CONSTRUCTION
Demolition and construction would take place over a 10-month period, which is anticipated to begin in June 2021 and end in March 2022, subject to regulatory approval.58 The project applicant proposes to demolish the existing buildings and remove almost all the existing on-site vegetation. Table 3-1 shows the approximate demolition and construction phasing.
Demolition would take place over a period of
approximately two weeks, while grading and site
preparation, including excavation for the subterranean
garage, would be completed over a two-month period.
Demolition and construction work would be conducted
between 7:00 a.m. to 8:00 p.m. on weekdays, as provided for in CMC Section 10.48.053, Grading, Construction and Demolition.

on weekends or holidays for sites within 750 feet of other residential properties.59 Demolition debris, including soil, would be off-hauled for disposal in accordance with the City of Cupertino’s Recycling and Diversion of Construction and Demolition Waste Ordinance.60 Debris to be hauled would include shrubs and trees that were planted as part of the existing urbanized landscape, 1,616 square feet of building demolition debris, 294 tons of asphalt/concrete material, and 14,100 cubic yards of grading and soil export. Typical equipment to be used for demolition and site preparation would include excavators, a skid steer loader, a grader, a rubber-tired dozer, scrapers, and an off-highway truck.
The project construction would consist of approximately 23,990 square feet of building space, 16,602 square feet of landscaped areas, and 20,395 square feet of hardscape (e.g., curb, gutters, planters, retaining walls, etc.). No pile driving, rock blasting, or crushing would occur during the construction phase.
Typical equipment to be used during construction of the project would include a backhoe, a crane, aerial lifts, a generator, a diesel pump, dumpers, rollers, and a paver.
During demolition and construction, vehicles, equipment, and materials would be staged and stored on a centrally located portion of the project site when practical. No long-term staging of equipment would occur around the perimeter of the site where adjacent to existing residential uses. No staging would occur in the public right-of-way. The construction site and staging areas would be clearly marked, and construction fencing would be installed to prevent disturbance and safety hazards. A combination of onand off-site parking facilities for construction workers would be identified during demolition, grading, and construction.
3.3 REQUIRED PERMITS AND APPROVALS
Following approval of this Initial Study and adoption of the Mitigated Negative Declaration, the following discretionary permits and approvals from the City would be required for the proposed project:
Zoning Map Amendment
Development Permit
Architectural and Site Approval Permit

Environmental Analysis
4.1 DISCUSSION OF ENVIRONMENTAL EVALUATION
The General Plan EIR included an analysis of the project site as potential Housing Element Site 9 (Foothill at McClellan Center – Foothill Market), although the adopted General Plan did not designate this site as a Priority Housing Element Site. The evaluation in the General Plan EIR assumed potential redevelopment of the existing commercial development to commercial and residential uses with 25 dwelling units per acre (or 27 net residential units) with a maximum of 30 feet in height. 61 The cumulative impacts of past, present, and probable future development, in conjunction with overall General Plan buildout, including residential development of the project site, were evaluated in the General Plan EIR. The proposed project is anticipated to be completed in 2022 (subject to regulatory approval); thus, this Initial Study presents an analysis of the near-term impacts of the proposed project under existing conditions and 2025 cumulative conditions. Although the project site was evaluated as Housing Element Site 9 in the General Plan EIR, the adopted General Plan does not designate this site as a Priority Housing Element Site in the Housing Element.62
Consistent with the analysis presented in the General Plan EIR, and due to the proposed project’s location in an urbanized city setting, the project would not have a significant effect on agriculture, forestry or mineral resources. Maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency categorize land within Cupertino as Urban and Built-Up Land.63 In addition, according to the 2006 mapping data from the California Department of Forestry and Fire Protection, the city does not contain any woodland or forestland cover.64 Finally, the city does not contain land zoned for farmland or timberland production.65 Consequently, there would be no impacts with regard to agriculture and forestry resources. The project site is not within an area designated as Mineral Resource Zone, which is an area containing mineral deposits.
66 Consequently, because the site has been developed and is not considered suitable for protection or conservation, there would be no impacts to mineral resources. For these reasons, these topics are not discussed further in this Initial Study. After the General Plan EIR was certified, the CEQA Guidelines were amended by the Governor’s Office of Planning and Research, which is the entity charged with developing guidelines to help agencies implement CEQA, and adequacy of parking 61 PlaceWorks. 2015.

c) If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area?
GENERAL PLAN EIR
Chapter 4.1, Aesthetics, of the General Plan EIR, addressed the impacts to visual resources associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. The impacts were found to be less than significant, and no mitigation measures were required.
EXISTING CONDITIONS
The project site contains partially vacant commercial buildings, a converted residential unit, and a vacant residential unit, bordered by surface parking and associated landscaping. The largest commercial building is a one-story building located on the west side of the project site and the second commercial building is a one-story building on the northeast corner of the project site. There is also a vacant, detached one-story residential unit on the northwest corner of the project site, with a detached shed and surrounding grassy areas. Surrounding uses include one to two-story single-family homes to the north, south, and west, with additional one to two-story homes across Stevens Canyon Road to the east. Landscaping on-site consists of one mature redwood tree and one mature palm tree in the southeast corner of the site, shrubs along Stevens Canyon Road, and mature trees and plantings surrounding the Cupertino Bike Shop and vacant residential unit.

REVISED FINAL DRAFT
DISCUSSION
a) Would the proposed project have a substantial adverse effect on a scenic vista? As discussed in Chapter 4.1, Aesthetics, of the General Plan EIR, the proposed project would have the potential to affect scenic vistas and/or scenic corridors if the redevelopment on the project site blocked views of areas that provide or contribute to such vistas. Potential effects could include blocking views of a scenic vista/corridor from specific publicly accessible vantage points or the alteration of the scenic vista/corridor. Such alterations could be positive or negative.
Public views of scenic corridors are views seen along a linear transportation route and public views of scenic vistas are views of specific scenic features. Scenic vistas are considered to be long-range views, while scenic corridors are comprised of short-, middle-, and long-range views. The General Plan does not have designated scenic corridors or vistas. However, for the purposes of this analysis, the westward views of the foothills and ridgelines of the Santa Cruz Mountains are considered scenic vistas, and the segment of I-280 from Santa Clara County line on the west to I-880 on the east also is considered a scenic corridor.
The analysis in the General Plan EIR found that building heights remaining at 30 feet would result in a lessthan-significant impact to the long-range views of the Santa Cruz Mountain Range and foothills because the maximum heights of the existing on-site and surrounding buildings and mature trees currently limit the opportunity for views of scenic vistas from street-level public viewing. The project location is not considered a destination public viewing point nor is it visible from scenic vistas.
As described in Chapter 3, Project Description, of this Initial Study, the existing buildings would be removed and replaced by the proposed mixed-use development with surface and underground parking, with all structures being 30 feet tall at the highest point. Of the two mature trees on the site, the Redwood tree on the northeast corner is proposed for removal, and the Palm tree on the southeast corner would remain.
Because the proposed project would not involve height increases above the surrounding development and are the same as what was evaluated in then General Plan EIR and currently permitted in the General Plan, and because existing conditions currently limit views of scenic resources combined with the fact that the site and surrounding areas are not public viewing locations, impacts would remain consistent with the conclusions in the General Plan EIR and would be less than significant. b) Would the proposed project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway? As discussed in Chapter 4.1, Aesthetics, of the General Plan EIR, the segment of I-280 in Cupertino is not an officially designated State Scenic Highway but is considered eligible for listing as a designated State Scenic Highway. The project site is approximately 1.4 miles to the south of the I-280/North Foothill Boulevard interchange, which is the arterial that connects the project site to I-280. The project site is not visible from I-280. Therefore, there would be no changes to the I-280 viewshed. 472

Impacts to views of scenic resources from the I-280 view corridor were determined to be less than significant in the General Plan EIR. Because the project proposes building heights that are consistent with what was evaluated in the General Plan EIR and the surrounding development, and are permitted in the General Plan, and because the site is not visible from the I-280 viewshed, project impacts would remain consistent with the conclusions in the General Plan EIR and would be less than significant. c) If the proposed project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
The project site is in an urbanized area that is not designated or otherwise identified as a public viewing location for surrounding scenic views. Public views of scenic resources including the westward views of the foothills and ridgelines of the Santa Cruz Mountains and the segment of I-280 from the Santa Clara County line on the west to I-880 on the east are partially obstructed under existing conditions due to the natural topography and the existing buildings in the project area.
The proposed project would result in a change from the existing one-story commercial and residential buildings to multiple two-story residential buildings and a mixed-use building, none of which would exceed the permitted height limit of 30 feet.
The project site is within the Commercial/Residential General Plan land use designation, which is intended to provide local neighborhood serving retail with residential densities compatible with the surroundings.67 The proposed project includes a zoning amendment to change the existing Planned Development with General Commercial (P(CG)), to Planned Development with General Commercial and Residential (P(CG,Res)). The proposed amendment to the Zoning Map would allow residential development on the site which would not conflict with any land use or zoning regulations governing scenic quality.
The proposed development would be required to provide suitable setbacks from public rights-of-way and appropriate buffers and/or height transitions for buildings adjacent to the surrounding low-density residential developments. Furthermore, the proposed project would increase the landscaping to include at least 19 new trees in addition to the one mature Palm tree that is located on the southeast corner of the project site which will remain as part of the project. The proposed landscaping would include planting 15-gallon screening Kohuhu shrubs (Pittosporum Tenuifolium) along the entire western and eastern project boundary, and approximately half of the rear project boundary. Additional landscaping along the northern boundary of the site along South Foothill Boulevard will partially screen the proposed development and would enhance the visual quality of the sidewalk abutting the property where no landscaping currently exists. Combined, the existing and proposed trees would help to preserve the existing visual setting.
Furthermore, the project is subject to the City’s discretionary review processes for the proposed Development Permit and Architectural and Site Approval Permit, in accordance with Chapters 19.12 and
19.168 of the Zoning Ordinance, which would ensure the proposed project would harmonize with adjacent development and not degrade the existing visual quality of the site and surrounding land uses. 67 City of Cupertino. 2015. City of Cupertino General Plan, Appendix A, Land Use Definitions. 473

Accordingly, consistent with the conclusions of the General Plan EIR, the proposed project would not substantially degrade the existing visual character of the site and its surroundings, or conflict with an applicable zoning and other regulations governing scenic quality and impacts would remain consistent with the conclusions in the General Plan EIR and would be less than significant. d) Would the proposed project create a new source of substantial light or glare that would adversely affect day or nighttime views in the area?
Nighttime illumination and glare impacts are the effects on adjoining uses and areas from a project’s exterior lighting. Light and glare impacts are determined through a comparison of the existing light sources with the proposed lighting plan or policies. As discussed in Chapter 4.1, Aesthetics, of the General Plan EIR, the project site and surrounding areas contain existing sources of nighttime illumination. These include street and parking area lights, and exterior lighting on existing commercial buildings. Additional light and glare in the overall all area would be caused by surrounding land uses and traffic on surrounding roadways. As described in Chapter 3, Project Description, of this Initial Study, the proposed project would redevelop the project site and replace the existing sources of light and glare with new sources that are similar to the existing uses and consistent with the surrounding land uses. The source, intensity, and type of exterior lighting for the project site would be typical for single-family homes and for orienting site residents and customers of the mixed-used building, and for overall safety needs (i.e., lighting on signs, sidewalks, and parking). All permanent on-site lighting would be low-level illumination, downward directed, and shielded to reduce light spill or glare onto surrounding residential homes as shown on Figure 3-14. There would be no up-lighting on the mixed-use building exterior. In landscaped and paved areas, light sources would be concealed and not visible from a public viewpoint. All exterior surface and aboveground mounted fixtures would be complementary to the architectural theme and to the surrounding residential uses.
The proposed project would not include reflective glass. Where glass features are considered, glazing treatments would vary and none of the exterior glass would have a light reflectance value of more than 15 percent.68 The second-floor balconies for the apartments would include railing elements, which could have a combination of UV coatings, frosting, and fritting, which reduces glare. The existing roadway and proposed landscaping surrounding the project would act as a buffer to prevent light spilling on to adjacent land uses. For these reasons, impacts would remain consistent with the conclusions in the General Plan EIR and would be less than significant.
68A light reflectance value or LRV is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. LRV is expressed as a percentage from 0 to 100; the higher the number the more visible light that is reflected. 474

GENERAL PLAN EIR
Chapter 4.2, Air Quality, of the General Plan EIR, addressed the air quality impacts associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Air quality impacts were found to be significant and unavoidable in the General Plan EIR because the project-specific details of future development were not available. The City adopted and incorporated mitigation measures into the General Plan to reduce air quality impacts. Mitigation Measures AQ-2a and AQ-2b are specific measures that are to be implemented by future projects, such as the proposed project, to reduce construction-related air quality impacts.
Mitigation Measure AQ-2a require applicants for future development projects to comply with the current Bay Area Air Quality Management District (BAAQMD) basic control measures for reducing fugitive dust emissions (PM10 and PM2.5) during construction and Mitigation Measure AQ-2b provides additional measures if there are significant construction exhaust emissions.
EXISTING CONDITIONS
The environmental setting normally constitutes the baseline physical conditions by which a lead agency determines whether an impact is significant (CEQA Guidelines Section 15125(a)). However, lead agencies have discretion to consider conditions over a range of time periods to account for a temporary lull or spike in operations. As with any commercial use, the buildings on the project site experience periodic transitions in tenants and occupancy. Therefore, this analysis considers full occupancy associated with historic operations of the existing commercial use as the baseline.
The existing commercial uses generate criteria air pollutants from transportation sources, energy use (natural gas and purchased energy), and area sources such as landscaping equipment and architectural 475

Air Pollutants of Concern
Criteria Air Pollutants
Pollutants emitted into the ambient air by stationary and mobile sources are regulated by federal and State law under the federal Clean Air Act (National) and California Clean Air Act, respectively. Air pollutants are categorized as primary and/or secondary pollutants. Primary air pollutants are those that are emitted directly from sources. Carbon monoxide (CO), reactive organic gases (ROG), nitrogen oxides (NOx), sulfur dioxide (SO2), coarse inhalable particulate matter (PM10), fine inhalable particulate matter (PM2.5), and lead (Pb) are primary air pollutants. Of these, all of them except for ROGs are “criteria air pollutants,” which means that ambient air quality standards (AAQS) have been established for them. The National and California AAQS are the levels of air quality considered to provide a margin of safety in the protection of the public health and welfare. They are designed to protect those “sensitive receptors” most susceptible to further respiratory distress, such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise.

adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed.
Toxic Air Contaminants
In addition to criteria air pollutants, both the State and federal government regulate the release of TACs.
The California Health and Safety Code Section 39655 defines a TAC as “an air pollutant which may cause or contribute to an increase in mortality or in serious illness, or which may pose a present or potential hazard to human health.” A substance that is listed as a hazardous air pollutant pursuant to Section 112(b) of the federal Clean Air Act (42 United States Code Section 7412[b]) is a toxic air contaminant. Under State law, the California Environmental Protection Agency, acting through the California Air Resources Board (CARB), is authorized to identify a substance as a TAC if it determines that the substance is an air pollutant that may cause or contribute to an increase in mortality or serious illness, or may pose a present or potential hazard to human health.
Where available, the significance criteria established by the BAAQMD are relied upon to make the determinations discussed below.
DISCUSSION
This section analyzes the types and quantities of air pollutant emissions that would be generated by the construction and operation of the proposed project at a project level. An update to the background discussion in the General Plan EIR of the air quality regulatory setting, meteorological conditions, existing ambient air quality in the vicinity of the project site, and air quality modeling is in Appendix A, Air Quality and Greenhouse Gas Emissions, of this Initial Study. The construction health risk assessment (HRA) for this project is in Appendix B, Health Risk Assessment, of this Initial Study. a) Would the project conflict with or obstruct implementation of the applicable air quality plan? BAAQMD is directly responsible for reducing emissions from area, stationary, and mobile sources in the San Francisco Bay Area Air Basin (SFBAAB) to achieve National and California AAQS. In April 2017, BAAQMD adopted its 2017 Clean Air Plan, which is a regional and multiagency effort to reduce air pollution in the SFBAAB. Regional growth projections are used by BAAQMD to forecast future emission levels in the SFBAAB. For the Bay Area, these regional growth projections are provided by the Association of Bay Area Governments (ABAG) and transportation projections are provided by the Metropolitan Transportation Commission (MTC) and are partially based on land use designations in city/county general plans. Typically, only large, regionally significant projects have the potential to affect the regional growth projections.
The proposed project would construct 18 residential units resulting in a density of 11.5 dwelling units per acre and, therefore, would not exceed the 15 dwelling units per acre limit designated in the General Plan or the 25 dwelling units per acre maximum that was evaluated in the General Plan EIR. Therefore, the proposed project would not directly result in any additional new population growth or employment growth beyond what was analyzed in the General Plan EIR. The proposed project is not considered a 477

regionally significant project under CEQA Guidelines Section 15206 that would affect regional vehicle miles traveled (VMT) and warrant intergovernmental review by ABAG and MTC.
As discussed in Section XII, Population and Housing, below, the proposed project would not exceed the level of population or housing projected in City or regional planning efforts (Plan Bay Area) through 2040, and it would not have the potential to substantially affect housing, employment, and population projections within the region, which is the basis of the 2017 Clean Air Plan projections. Furthermore, the proposed project would create a net decrease in emissions on-site and would not exceed the BAAQMD’s emissions thresholds (see Operational Impacts discussion in criterion (b) below). The BAAQMD emissions thresholds were established to identify projects that have the potential to generate a substantial amount of criteria air pollutants. Because the proposed project would result in an air quality benefit, the proposed project would not be considered by the BAAQMD to be a substantial emitter of criteria air pollutants.
Therefore, the proposed project would not conflict with or obstruct implementation of the 2017 Clean Air Plan and impacts would be considered less than significant. b) Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project area is in non-attainment under applicable federal or State ambient air quality standards? This section analyzes potential impacts related to air quality that could occur from a combination of the proposed project with other past, present, and reasonably foreseeable projects within the SFBAAB. The SFBAAB is currently designated a nonattainment area for California and National O3, California and National PM2.5, and California PM10 AAQS. Any project that produces a significant project-level regional air quality impact in an area that is in nonattainment adds to the cumulative impact. Due to the extent of the area potentially impacted by cumulative plus project emissions (the SFBAAB), a project’s contribution to a cumulative impact is cumulatively considerable when project-related emissions exceed the BAAQMD emissions thresholds.
BAAQMD has identified thresholds of significance for criteria pollutant emissions and criteria air pollutant precursors, including ROG, NOx, PM10, and PM2.5. Development projects below the significance thresholds would not generate sufficient criteria pollutant emissions to violate any air quality standard or contribute substantially to an existing or projected air quality violation. The following describes changes in regional impacts from short-term construction activities and long-term operation of the proposed project.
Regional Short-Term Construction Impacts
Construction activities produce combustion emissions from various sources, such as on-site heavy-duty construction vehicles, vehicles hauling materials to and from the site, and motor vehicles transporting the construction crew. Site preparation activities produce fugitive dust emissions (PM10 and PM2.5) from demolition and soil-disturbing activities, such as grading and excavation. Air pollutant emissions from construction activities on site would vary daily as construction activity levels change. Construction activities associated with the project would result in emissions of ROG, NOx, CO, PM10, and fine PM2.5. 478

Construction Fugitive Dust
Ground disturbing activities during construction would generate fugitive dust (PM10 and PM2.5). The amount of dust generated during construction would be variable and is dependent on the amount of material being disturbed, the type of material, moisture content, and meteorological conditions. If uncontrolled, PM10 and PM2.5 levels downwind of actively disturbed areas could possibly exceed State standards. BAAQMD considers all impacts related to fugitive dust emissions from construction to be less than significant with implementation of BAAQMD’s best management practices shown in Mitigation Measure AQ-1, which is required pursuant to General Plan EIR Mitigation Measure AQ-2a.
Impact AQ-1: Fugitive dust (PM10 and PM2.5) generated by the proposed project during construction could potentially result in significant regional short-term air quality impacts without implementation of the Bay Area Air Quality Management District’s best management practices related to reducing fugitive dust emissions.
Mitigation Measure AQ-1: The project’s construction contractor shall comply with the following best management practices for reducing construction emissions of fugitive dust (PM10 and PM2.5) as required by the Bay Area Air Quality Management District Revised California Environmental Quality Act Air Quality Guidelines:
Water all active construction areas at least twice daily, or as often as needed to control dust emissions. Watering should be sufficient to prevent airborne dust from leaving the site. Increased watering frequency may be necessary whenever wind speeds exceed 15 miles per hour. Reclaimed water should be used whenever possible.
Pave, apply water twice daily or as often as necessary to control dust, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites. Cover all trucks hauling soil, sand, and other loose materials. Sweep daily (with water sweepers using reclaimed water if possible) or as often as needed all paved access roads, parking areas and staging areas at the construction site to control dust. Sweep public streets daily (with water sweepers using reclaimed water if possible) in the vicinity of the project site, or as often as needed, to keep streets free of visible soil material. Hydroseed or apply non-toxic soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply non-toxic soil binders to exposed stockpiles (dirt/sand). Limit vehicle traffic speeds on unpaved roads to 15 miles per hour. Replant vegetation in disturbed areas as quickly as possible and water appropriately until vegetation is established.
Install sandbags or other erosion control measures to prevent silt runoff from public roadways. All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe.
Construction Exhaust Emissions
Analysis of construction emissions is based on the preliminary construction duration and normalized California Emissions Estimator Model (CalEEMod) default schedule developed for the proposed project.

parking that would occur near existing sensitive land uses. Construction emissions were quantified using the CalEEMod Version 2016.3.2.25 based on information provided by the project applicant, which was reviewed and approved by PlaceWorks and the City. The approximately 10-month construction period is assumed to begin in June 2021 and end in March 2022, subject to regulatory approval.
Potential construction-related air quality impacts are determined by comparing the average daily criteria air pollutants emissions generated by the proposed project-related construction activities to the BAAQMD significance thresholds in Table 4-2. Average daily emissions are based on the annual construction emissions divided by the total number of active construction days.

Operational Impacts
Typical long-term air pollutant emissions are generated by area sources (e.g., landscape fuel use, aerosols, architectural coatings, and asphalt pavement), energy use (natural gas), and mobile sources (i.e., on-road vehicles). The proposed project would result in new housing units, a parking garage, commercial space, and paved and landscaped surfaces, and associated vehicular trips. 480

Table 4-3 identifies a net decrease in criteria air pollutant emissions associated with the proposed project compared to the baseline operation. As shown in Table 4-3, the operational emissions generated by the project would not exceed the BAAQMD daily pounds per day or annual tons per year project level threshold.70 Therefore, the proposed project would not cumulatively contribute to the nonattainment designations of the SFBAAB and would result in an air quality benefit, by providing less criteria air pollutant emissions than existing conditions. Project-related operation activities to the regional air quality would be less than significant.

Summary
As described, the proposed project would not have a significant long-term operational phase impact, however, without incorporation of fugitive dust control measures, construction activities could potentially result in significant regional short-term air quality impacts. Mitigation Measure AQ-1, required by the General Plan Mitigation Measure AQ-2a, would ensure that required fugitive dust control measures are implemented to control project-related fugitive dust generated during construction activities. Therefore, the project’s contribution to cumulative air quality impacts would be less than significant. c) Would the project expose sensitive receptors to substantial pollutant concentrations? Development of the proposed project could expose sensitive receptors to elevated pollutant concentrations. Unlike the construction emissions shown in Table 4-2 in criterion (b), described in pounds per day, localized concentrations refer to an amount of pollutant in a volume of air (parts per millions [ppm] or micrograms per cubic meter [µg/m3
]) and can be correlated to potential health effects.
Construction Off-Site Community Risk and Hazards
The proposed project would elevate concentrations of TACs and PM2.5 in the vicinity of sensitive land uses during construction activities. The nearest sensitive receptors to the project site include the adjacent onestory and two-story single-family residences approximately 20 to 50 feet from the site property lines to the north, west, and south. BAAQMD has developed screening tables for air toxics evaluation during construction that evaluate construction-related health risks associated with residential, commercial, and industrial projects.71 According to the screening tables, the surrounding residences are closer than the distance of 100 meters (328 feet) that would screen out potential health risks, and therefore, could be potentially impacted from the proposed construction activities. Consequently, a site-specific construction health risk assessment (HRA) of TACs and PM2.5 has been prepared (see Appendix B of this Initial Study).
A quantified analysis of the project’s construction emissions was conducted using the CalEEMod, Version 2016.2.25. Construction emissions were based on a 10-month construction duration, construction schedule, and off-road equipment list provided by the project applicant. The United States Environmental Protection Agency AERMOD, Version 9.7, dispersion modeling program was used to determine flagpole level pollutant concentrations, which were used to estimate excess lifetime cancer risk, chronic noncancer hazard index for non-carcinogenic risk, and the PM2.5 maximum annual concentrations at the nearest sensitive receptors. Results of the analysis are shown in Table 4-4. 71 Bay Area Air Quality Management District (BAAQMD), Screening Tables for Air Toxics Evaluation During Construction, Version

The results of the HRA are based on the maximum receptor concentration over a 10-month construction exposure duration for off-site receptors.72 Risk is based on the updated Office of Environmental Health Hazard Assessment (OEHHA) Guidance Manual:73
Cancer risk for the maximum exposed off-site resident from only construction activities related to the proposed project were calculated to be 58.4 in a million and would exceed the BAAQMD’s 10 in one million significance threshold. Utilizing the latest 2015 OEHHA Guidance Manual, the calculated total cancer risk conservatively assumes that the risk for the maximum exposed receptor (MER) consists of a pregnant woman in the third trimester that subsequently gives birth to an infant during the approximately 10-month construction period; therefore, all calculated risk values were multiplied by a factor of 10. In addition, it was conservatively assumed that the residents were outdoors 8 hours a day, 260 construction days per year, and were exposed to all of the daily construction emissions. For non-carcinogenic effects, the hazard index identified for each toxicological endpoint totaled less than one for off-site sensitive receptors from the proposed project. Therefore, chronic noncarcinogenic hazards are within acceptable limits. The highest PM2.5 annual concentrations at the maximum exposed off-site sensitive resident would exceed the BAAQMD significance threshold of 0.3 µg/m3
. Therefore, PM2.5 emissions are not within
acceptable limits.
Because the incremental cancer risk and maximum annual PM2.5 concentrations for the maximum exposed receptor would exceed BAAQMD’s significance thresholds due to construction activities associated with the proposed project, impacts are potentially significant, and the following mitigation is required.
Impact AQ-2: The proposed project could expose sensitive receptors to substantial pollutant concentrations during construction.
72 Under the 2015 Office of Environmental Health Hazard Assessment Air Toxics Hot Spots Program Guidance Manual, the exposure duration has changed from 70 years to 30 years for operational risk to residents; however, the risk is still averaged over a 70-year lifetime. 73 Office of Environmental Health Hazard Assessment, 2015.

Mitigation Measure AQ-2: During construction, the construction contractor(s) shall:
Use construction equipment that have engines that meet either the United States Environmental Protection Agency (USEPA) or California Air Resources Board (CARB) Tier 4 Interim emissions standards for off-road diesel-powered construction equipment with more than 50 horsepower, unless it can be demonstrated to the City of Cupertino Building Division that such equipment is not available. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by Tier 4 Interim emissions standards for a similarly sized engine, as defined by the CARB’s regulations. Prior to issuance of any construction permit, ensure that all construction plans submitted to the City of Cupertino Planning Department and/or Building Division clearly show the requirement for Tier 4 Interim emissions standards for construction equipment more than 50 horsepower. Maintain a list of all operating equipment in use on the project site for verification by the City of Cupertino Building Division official or their designee. The construction equipment list shall state the makes, models, and number of construction equipment on site. Ensure that all equipment shall be properly serviced and maintained in accordance with the manufacturer’s recommendations.
Communicate with all sub-contractors in contracts and construction documents that all nonessential idling of construction equipment is restricted to 5 minutes or less in compliance with CARB Rule 2449 and is responsible for ensuring that this requirement is met.
Mitigation Measure AQ-2, which is not a General Plan EIR mitigation measure, would reduce the project’s localized construction emissions, as shown in the Table 4-5 below. The results indicate that, with mitigation, cancer risk and PM2.5 impacts would be less than the BAAQMD’s significance thresholds for residential-based receptors. Therefore, the project would not expose off-site sensitive receptors to substantial concentrations of air pollutant emissions during construction and impacts would be less than significant.

proposed project would not include stationary sources that emit TACs and would not generate a significant amount of heavy-duty truck trips (a source of diesel particulate matter [DPM]). Therefore, the proposed project would not expose sensitive receptors to substantial concentrations of air pollutant emissions during operation, and impacts would be less than significant.
Carbon Monoxide (CO) Hotspot Analysis
Areas of vehicle congestion have the potential to create pockets of carbon monoxide (CO), which are called hotspots. These pockets have the potential to exceed the State 1-hour standard of 20 ppm or the 8- hour standard of 9 ppm. The proposed project would not conflict with the Santa Clara Valley Transportation Authority (VTA) Congestion Management Program (CMP) because it would not hinder the capital improvements outlined in the CMP or alter regional travel patterns. VTA’s CMP must be consistent with MTC’s/ABAG’s Plan Bay Area. An overarching goal of the regional Plan Bay Area 2040 is to concentrate development in areas where there are existing services and infrastructure rather than locate new growth in outlying areas where substantial transportation investments would be necessary to achieve the per capita passenger vehicle, vehicle miles traveled, and associated GHG emissions reductions. The proposed project is an infill residential development that is in close proximity to existing employment centers, roadways, transit, and bicycle and pedestrian routes, and for these reasons would be consistent with the overall goals of Plan Bay Area 2040.
Furthermore, under existing and future vehicle emission rates, a project would have to increase traffic volumes at a single intersection by more than 44,000 vehicles per hour—or 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited—in order to generate a significant CO impact. Implementation of the proposed project would not increase traffic volumes at affected intersections by more than 44,000 vehicles per hour or 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (see Section XV, Transportation, below). 74 Therefore, impacts
associated with CO hotspots would be less than significant. d) Would the project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Construction and operation of mixed-use developments would not generate odors that would affect a substantial number of people. The type of facilities that are considered to have objectionable odors include wastewater treatments plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch plants, chemical manufacturing, and food manufacturing facilities. While residential uses are not associated with foul odors that constitute a public nuisance, the proposed mixeduse building would have 4,536 square feet of neighborhood-serving commercial space on the ground floor that could include a food service such as a small coffee shop or a bakery that could generate odors to nearby off-site residents. For these types of uses, the City may require charcoal activated filters to be 74 Bay Area Air Quality Management District (BAAQMD), 2011 Revised.

installed depending on what tenants lease the space over the life of the building operation. However, these are not the types of uses that lead to odors that affect a substantial number of people.
During construction activities, construction equipment exhaust and application of asphalt and architectural coatings would temporarily generate odors. Any construction-related odor emissions would be temporary and intermittent. Additionally, noxious odors would be confined to the immediate vicinity of the construction equipment. By the time such emissions reach any sensitive receptor sites, they would be diluted to well below any level of air quality concern.
Odors are also regulated under BAAQMD Regulation 1, Rule 1-301, Public Nuisance, which states that “no person shall discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance or annoyance to any considerable number of persons or the public; or which endangers the comfort, repose, health or safety of any such persons or the public, or which causes, or has a natural tendency to cause, injury or damage to business or property.” Therefore, because construction-related odor emissions would be temporary and intermittent, mixed-use developments such as the proposed project are not considered the type of use that would generate odors that would affect a substantial number of people, and the proposed project is required to comply with BAAQMD Regulation 7, odor-related impacts to off-site land uses would be less than significant.

GENERAL PLAN EIR
Chapter 4.3, Biological Resources, of the General Plan EIR, addressed the impacts to biological resources associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Impacts to biological resources were found to be less than significant with implementation of mitigation measures to ensure impacts to birds protected under the Migratory Bird Treaty Act (MBTA) would not be significant. The project is required to comply with General Plan EIR Mitigation Measure BIO-1, previously adopted and incorporated into the General Plan, to ensure the protection of nesting raptors and other birds when in active use, as required by the federal MBTA and the California Fish and Game Code (CFG Code).
EXISTING CONDITIONS
The project site and surrounding area is urbanized and contains roadways, structures, and other impervious surfaces. There are two mature trees on site, a Redwood tree proposed for removal, and a Palm tree that will remain. Existing conditions on and adjacent to the project site are developed and primarily dominated by landscaped and non-native vegetation. Based on a review of historical aerial photographs, the project site has been subject to historic disturbance, including mass grading. These conditions do not lend themselves to presence of rare plant and animal populations, and such species are not anticipated to be present prior to or during project construction.
As previously described in Chapter 3, Project Description, the CALVEG75 habitat mapping program classifies the site as an “urban area” that tends to have low to poor wildlife habitat value due to replacement of natural communities, fragmentation of remaining open space areas and parks, and intensive human disturbance. The diversity of urban wildlife depends on the extent and type of landscaping and remaining open space, as well as the proximity to natural habitat. Trees and shrubs used for landscaping provide nest sites and cover for wildlife adapted to developed areas. Typical native bird species in the city of Cupertino include the mourning dove, scrub jay, northern mockingbird, American robin, brown towhee, American crow, and Anna’s hummingbird, among others. Introduced species include the rock dove, European starling, house finch, and house sparrow. Urban areas can also provide habitat for several species of native mammals such as the California ground squirrel and striped skunk, as well as the introduced eastern fox squirrel and eastern red fox. Introduced pest species such as the Norway rat, house mouse, and opossum are also abundant in developed areas.
A recent search of the CNDDB shows that the project site does not contain any known special-status species on-site. However, special-status plant and animal species have been recorded within 5 miles of the project site. All of these special-status species were recorded outside of or near the city limits except for the Western leatherwood (Dirca occidentalis), Woodland woollythreads (Monolopia congdonii), Cooper’s hawk (Accipiter cooperi), White-tailed kite (Elanus leucurus), American peregrine falcon (Falco peregrinus), California tiger salamander (Ambystoma californiense, and the Santa Cruz black salamander (Aneides 75 The CALVEG system was initiated in January 1978 by the Region 5 Ecology Group of the US Forest Service to classify California’s existing vegetation communities for use in statewide resource planning.

flavipunctatus niger). These special-status species were not recorded near the site but at least 1 mile away.
The nests of most bird species are protected under the MBTA when in active use and there is a remote possibility that one or more species protected under the MBTA and CFG Code, could nest in the two existing trees and other landscaping on the project site. These include both the Cooper’s hawk (Accipiter cooperi) and white-tailed kite (Elanus leuocurus), which have reported CNDDB occurrences within the city boundary, together with more common raptors such as red-tailed hawk, great horned owl, and American kestrel, all of which are protected by the MBTA and CFG Code when their nests are in active use. However, no essential habitat for these or other special-status species is present on the site due to its developed condition.
Numerous bat species found in the Cupertino area, most of which are relatively common, and are not considered special-status species. As previously stated, the CNDDB does not show any occurrences of special-status bats on the site vicinity but does show records within several miles of Cupertino. The records include occurrences of Townsend’s big-eared bat (Corynorhinus townsendii), hoary bat (Lasiurus cinereus), and Yuma myotis (Myotis yumanensis). These three species have no legal protected status under the State or federal Endangered Species Acts, but Townsend’s big-eared bat is considered a Species of Special Concern by the California Department of Fish and Wildlife. These species have various priority rankings with the Western Bat Working Group, ranging from “High” for Townsend’s big-eared bat, “Medium” for hoary bat, to “Low-Medium” for Yuma myotis. Bat species found in the Cupertino vicinity may forage and occasionally roost in the site vicinity, but suitable habitat conditions for maternity roots does not exist on the site.
Wetlands and jurisdictional waters within the city boundary include creek corridors and associated riparian scrub and woodland, and areas of freshwater marsh around ponds, seeps, springs, and other waterbodies. Some remnant stands of riparian scrub and woodland occur along segments of the numerous creeks through the urbanized valley floor. The project site does not contain these creek corridors or contain other regulated waters; however, the Stevens Creek Corridor is approximately 0.25 miles to the east of the project site. Single-family residential neighborhoods act as a barrier between Stevens Creek and the project site.
There is no existing wildlife movement corridor designation on the site by any agency, including the United States Fish and Wildlife or the California Department of Fish and Wildlife. Furthermore, there are no open space areas or natural lands adjacent to the project site.
The existing palm tree located on the southeastern of the project site would remain as part of the proposed project. The redwood tree on the northern part of the project site would be removed. 488

DISCUSSION
a) Would the project have a substantial adverse effect, either directly or through habitat modifications, on a plant or animal population, or essential habitat, defined as a candidate, sensitive or special-status species?
As stated above in the existing conditions discussion, there are no known occurrences of special-status plant or animal species and no suitable habitat for such species on the project site, but there is a possibility that birds that are protected by the MBTA and CFG Code could nest in trees and other landscaping on the project site. However, no essential habitat for these or other special-status species is present on the site due to its developed condition. The analysis in the General Plan EIR found that impacts to special-status species, including nesting birds, would be reduced to less than significant with mitigation.
Accordingly, the implementation of Mitigation Measure BIO-1, which is required by General Plan EIR Mitigation Measure BIO-1, would also be required for the project to reduce impacts to a less-thansignificant level.
Nesting Birds
The analysis in the General Plan EIR found that impacts to special-status species, including nesting birds, would be reduced to less than significant with mitigation. Accordingly, the implementation of Mitigation Measure BIO-1, which is required by General Plan EIR Mitigation Measure BIO-1, would also be required for the project to reduce impacts to a less-than-significant level.
Impact BIO-1: Tree removal and demolition activities during site clearance could destroy active nests, and/or otherwise interfere with nesting of birds protected under federal and State law.
Mitigation Measure BIO-1: Nests of raptors and other birds shall be protected when in active use, as required by the federal Migratory Bird Treaty Act and the California Fish and Game Code. The construction contractor shall indicate the following on all construction plans, if construction activities and any required tree removal occur during the breeding season (February 1 and August 31). Preconstruction surveys shall:
Be conducted by a qualified biologist prior to tree removal or grading, demolition, or construction activities. Note that preconstruction surveys are not required for tree removal or construction, grading, or demolition activities outside the nesting period. Be conducted no more than 14 days prior to the start of tree removal or construction. Be repeated at 14-day intervals until construction has been initiated in the area after which surveys can be stopped.
Document locations of active nests containing viable eggs or young birds. Protective measures for active nests containing viable eggs or young birds shall be implemented under the direction of the qualified biologist until the nests no longer contain eggs or young birds, and the young have left the nest and are foraging independently, or the nest is no longer active.
Protective measures shall include:

Establishment of clearly delineated exclusion zones (i.e., demarcated by identifiable fencing, such as orange construction fencing or equivalent) around each nest location as determined by the qualified biologist, taking into account the species of birds nesting, their tolerance for disturbance and proximity to existing development. In general, exclusion zones shall be a minimum of 300 feet for raptors and 75 feet for passerines and other birds. Monitoring active nests within an exclusion zone on a weekly basis throughout the nesting season to identify signs of disturbance and confirm nesting status. An increase in the radius of an exclusion zone by the qualified biologist if project activities are determined to be adversely affecting the nesting birds. Exclusion zones may be reduced by the qualified biologist only in consultation with the California Department of Fish and Wildlife.
Bird Collision
Avian injury and mortality resulting from collisions with buildings, towers and other man-made structures is a common occurrence in city and suburban settings. Some birds are unable to detect and avoid glass and have difficulty distinguishing between actual objects and their reflected images, particularly when the glass is transparent and views through the structure are possible. Night-time lighting can interfere with movement patterns of some night-migrating birds, causing disorientation or attracting them to the light source. The frequency of bird collisions in a particular area is dependent on numerous factors, including:
characteristics of building height, fenestration (the arrangement of windows and doors on the elevations of a building) and exterior treatments of windows and their relationship to other buildings and vegetation in the area; local and migratory avian populations, their movement patterns, and proximity of water, food and other attractants, time of year; prevailing winds; weather conditions; and other variables.
The proposed mixed-use building and residential buildings would alter the physical characteristics of the site; however, this change is not expected to contribute to a substantial increase in the risk of collisions to local and migratory birds. This is due to several reasons, including the fact that the site is currently developed with residential buildings of a similar height (30 feet), bulk, and surface treatment, as is the current surrounding area; that the existing site has few trees; and the proposed structures would have limited transparency (i.e., no large uninterrupted windows in the new buildings). Because the site vicinity is already developed with urban use and the site is currently developed with occupied structures, most birds, as under existing conditions, would likely acclimate to the presence of the new building once completed. The potential risk of bird collision with the new buildings would be extremely low.
While the design of the exterior treatment of the proposed buildings is in the conceptual phase and has not yet been finalized, and must still go through Design Review, there are design options to minimize the risk of bird collisions by using well-documented bird-safe designs for window treatments, roof top equipment, and night-time lighting. While any bird collisions that do occur should not have a substantial adverse effect on special-status bird species or more common bird species that may be flying through the vicinity, the applicant, as described in Chapter 3, Project Description, has committed to implementing bird-safe design measures in the new buildings, which would further address the low risk of collision.
These include the following measures that would be part of the design of the new building:

REVISED FINAL DRAFT
Non-Reflective Glass: No reflective glass would be used in the building consistent with the San Francisco Bird Safe Recommendations76 that state that reflective glass should be avoided, because some birds in certain circumstances might see vegetation in the reflection and fly into a building.
None of the exterior glass in the new buildings will have a light reflectance value of more than 15 percent.
Fritted Glass: Fritted glass is a non-reflective glass that is used to reduce glare and lower the danger to birds. Using fritted glass on the ground floor and second story windows and balcony railing elements, of the new mixed-use building would help prevent possible bird strikes. Fritting helps diminish the transparency of glass and is a documented approach to helping reduce the probability of bird collisions. Transparent glass used in “design traps” such as glass bridges or parapets can also be problematic. The project proposes glass railing elements on the second-floor balconies, which would incorporate UV coatings, frosting, and fritting to make them visible to birds to reduce collisions. Building Lighting: Overly lit buildings can be problematic, especially if there is up-lighting. The project is required to meet City code minimum standards on exterior lighting, and the new building would have no up-lighting. The source, intensity, and type of exterior lighting for the project site would generally be provided for the purpose of orienting site users and for safety needs. All on-site lighting would be low-level illumination and shielded to reduce light spill or glare. Tree Screening: The proposed project includes new 5-foot screening shrubs to be planted along the north, south, western, and the northern and southern edges of the eastern borders of the project site and 15 new trees, including one Miami crape myrtles (Lagerstroemia I. ‘Miami’), seven Saratoga bay laurels (Laurus ‘Saratoga’), and seven Coast live oak (Quercus agrifolia). Shrubs, including Cape rush (Chondropetalum tectorum) and Dwarf yeddo hawthorn (Rhaphiolepis U. ‘Minor’) would be planted along the eastern portion of the site, shielding the glass façade. These trees would help shield the first floors, which shielding would increase as the new trees grow over time.
The location of the project site, the building design features and selected materials, were determined to adequately address the remote potential for special-status bird species dispersing through the site vicinity to collide with the new structure and be injured or killed. These measures would serve to minimize the potential for bird strikes through the use of bird-friendly design guidelines in the treatment of windows and other aspects of the proposed buildings, and would ensure any potential impact would be less than significant for special-status birds and more common bird species.
Additionally, should the draft City of Cupertino draft Bird Safe Design Ordinance described in Chapter 3, Project Description, in Section 3.1.4.3, Other Requirements, be adopted by the City Council prior to project construction, the project applicant would be required to comply with the standards in the Ordinance which would also ensure any potential impact would be less than significant for special-status birds and more common bird species.

Roosting Bats
As described in the existing conditions, the CNDDB records were recently searched for, among other species, occurrences of Townsend’s big-eared bat (Corynorhinus townsendii), hoary bat (Lasiurus cinereus), and Yuma myotis bat (Myotis yumanensis). These three species have no legal protected status under the State or federal Endangered Species Acts, but Townsend’s big-eared bat is considered a Species of Special Concern by the California Department of Fish and Wildlife. Bat species found in the Cupertino vicinity may forage and occasionally roost in the site vicinity, but suitable habitat conditions for maternity roosts is absent from the site. The potential for any special-status bat species to be present on the site is considered highly remote, given the urbanization of the site vicinity and intensity of human activity, which typically discourages possible occupation by special-status bats. Accordingly, the construction and operation of the proposed project would not result in the inadvertent loss of any bats and impacts would be less than significant.
b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community type?
As discussed in the existing conditions above, the proposed project is located in an urbanized area where no sensitive natural communities are found. The nearest creek is Stevens Creek, located approximately
0.25 miles to the east of the project site. The existing single-family residential neighborhoods act as a barrier between Stevens Creek and the project site. Based on the existing conditions and the fact that the proposed project would redevelop and underdeveloped site, impacts would be consistent with the conclusions in the General Plan EIR and would remain less than significant. c) Would the project have a substantial adverse effect on federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
As discussed in the existing conditions and determined in the General Plan EIR, development of the proposed project would occur in urbanized areas where no wetlands or jurisdictional waters occur on or near the project site; therefore, no impact would occur directly. Indirect impacts to wetlands and jurisdictional or other waters include: 1) an increase in the potential for sedimentation due to construction grading and ground disturbance, 2) an increase in the potential for erosion due to increased runoff volumes generated by impervious surfaces, and 3) an increase in the potential for water quality degradation due to increased levels in non-point pollutants. However, indirect impacts would be largely avoided through effective implementation of best management practices during construction and compliance with water quality controls. As discussed in Impact HYDRO-1, water quality impacts from construction and operation of the proposed project would be less than significant. Accordingly, indirect impacts to wetlands and jurisdictional waters would remain consistent with the conclusions in the General Plan EIR and would be less than significant.

d) Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species, their wildlife corridors or nursery sites? Development on the project site would occur in an urbanized area where sensitive wildlife resources and important wildlife movement corridors are no longer present because of the existing development.
Wildlife species common to urban and suburban habitat could be displaced where existing structures are demolished and landscaping is removed as part of future development, but these species are relatively abundant, and adapted to human disturbance. As discussed in Chapter 3, Project Description, of this Initial Study, the proposed project would remove one mature Redwood tree on-site and most landscaping, and would replace the landscaping with additional trees and plants that would provide replacement habitat for wildlife species that may have adapted to the project site. Proposed project landscaping includes native, drought tolerant landscaping that is beneficial to the environment. Therefore, project impacts on the movement of fish and wildlife, wildlife corridors, or wildlife nursery sites would be would remain consistent with the conclusions in the General Plan EIR and would be less than significant. e) Would the project conflict with any local ordinances or policies protecting biological resources? As discussed in criteria (a) through (d), above, the project site is located in an urbanized area where sensitive biological and wetland resources are considered to be absent, and no major conflicts with the relevant policies or ordinances related to biological resources in the General Plan and/or CMC would occur. One tree is proposed to be removed as part of the project. However, because the existing development is on property that requires a development application, all existing trees on the site are considered protected.77 Therefore, compliance with the City’s Tree Ordinances (CMC Chapter 14.12 and Chapter 14.18), which requires replacement trees, would ensure impacts related to the removal of trees would remain consistent with the conclusions in the General Plan EIR and would be less than significant. f) Would the project conflict with an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional, or State habitat conservation plan? No adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved conservation plan includes the city or the project site, and the proposed project would not conflict with any adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved conservation plan. Impacts would remain consistent with the conclusions in the General Plan EIR and no impact would occur.

GENERAL PLAN EIR
Chapter 4.4, Cultural Resources, of the General Plan EIR, addressed the impacts to cultural and Tribal Cultural Resources (TCRs) associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. The impacts were found to be less than significant, and no mitigation measures were required. The following is a summary of Section, 4.4.1.2, Existing Conditions, of Chapter 4.4, which is based on the cultural resource analysis conducted by Tom Origer & Associates on July 24, 2013, included as Appendix D, Cultural Resources Data, of the General Plan EIR. The cultural resources study consists of archival research at the Northwest Information Center at Sonoma State University, examination of the library and files, field inspection, and contact with the Native American community. As shown in Table 4.4-2, Cultural Resources in the Project Study Area and Vicinity, and on Figure 4.4-1, Cultural Resources, of the General Plan EIR, there are no identified cultural resources on the project site.

DISCUSSION
a) Would the project cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5?
Under CEQA, both prehistoric and historic-period archaeological sites may qualify as historical resources.80 Archaeological resources are addressed in criterion (b), and human remains are addressed below in criterion (c), below.
As discussed above in the existing conditions, the project site was developed in 1948 and again in 1968.
As further described above, the existing buildings do not meet the criteria for listing in the California Register of Historical Resources. The General Plan EIR did not identify the project site as having existing buildings that are considered historic resources, and the existing buildings are not currently listed as California Historical Resources.81 Accordingly, impacts would remain consistent with the conclusions in the General Plan EIR and less-than-significant impacts to historical architectural resources would occur as a result of project development.
b) Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5?
While the project site is currently developed and the cultural resources study prepared for the General Plan EIR82 did not identify any known archaeological deposits on the project site, the site could still contain subsurface archaeological deposits, including unrecorded Native American prehistoric archaeological materials. If subsurface historical and pre-contact archaeological deposits that meet the definition of historical resource under CEQA Section 21084.1 or CEQA Guidelines Section 15064.5 are present at the project site, they could be damaged or destroyed by ground-disturbing construction activities (e.g., site preparation, grading, excavation, and trenching for utilities) associated with development allowed under the proposed project. Should this occur, the ability of the deposits to convey their significance, either as containing information about prehistory or history, or as possessing traditional or cultural significance to Native American or other descendant communities, would be materially impaired. Therefore, any project-related ground-disturbing activities have the potential to affect subsurface prehistoric archaeological resources that may be present. Implementation of Mitigation Measure CULT-1, which is not a General Plan EIR mitigation measure, would reduce impacts to unknown archaeological deposits to a less-than-significant level.
Impact CULT-1: The proposed project could cause a substantial adverse change in the significance of an archaeological resource pursuant to CEQA Guidelines Section 15064.5. 80 California Code of Regulations, Title 14, Chapter 3, Section 15064.5(c), Determining the Significance of Impacts on Historical and Unique Archeological Resources. 81 Office of Historic Preservation, Listed California Historical Resources.

Mitigation Measure CULT-1: A tribal representative from the Tamien Nation shall be retained and permitted on-site at all times during ground disturbance (including grading, demolition and/or construction) to monitor for potential prehistoric or historic subsurface cultural resources. Notice shall be given to the Tribe Tamien Nation in a manner requested by the Tribe Tamien Nation at least 48 hours five (5) days before any ground disturbing activity. Prior to ground disturbance activities, construction workers conducting the ground disturbing activities shall undergo cultural resource sensitivity training conducted by the on-site tribal Tamien Nation representative.
If any prehistoric or historic subsurface cultural resources are discovered during ground-disturbing (including grading, demolition and/or construction) activities:
All work within 50 feet of the resources shall be halted, the City shall be notified, and a qualified archaeologist and tribal Tamien Nation representative shall be consulted. The contractor shall cooperate in the recovery of the materials. Work may proceed on other parts of the project site while mitigation for tribal cultural resources, historical resources or unique archaeological resources is being carried out.
The qualified archaeologist shall prepare a report for the evaluation of the resource to the California Register of Historical Places and the City Building Department. The report shall also include appropriate recommendations in collaboration with a tribal Tamien Nation representative regarding the significance of the find and appropriate mitigations as follows:
If the resource is a non-tribal resource, the archaeologist shall assess the significance of the find according to CEQA Guidelines Section 15064.5.
If the resource is a tribal resource – whether historic or prehistoric – the consulting archaeologist shall consult with the appropriate tribe(s) Tamien Nation to evaluate the significance of the resource and to recommend appropriate and feasible avoidance, testing, preservation, or mitigation measures, in light of factors such as the significance of the find, proposed project design, costs, and other considerations. If avoidance is infeasible, other appropriate measures (e.g., data recovery) may be implemented.
All significant non-tribal cultural materials recovered shall be, as necessary, and at the discretion of the consulting archaeologist, subject to scientific analysis, professional museum curation, and documentation according to current professional standards. c) Would the project disturb any human remains, including those interred outside of formal cemeteries? There are no known human remains on the project site; however, the potential to unearth unknown human remains during ground disturbing activities associated with the construction of the project could occur. Any human remains encountered during ground-disturbing activities associated with the proposed project would be subject to federal, State, and local regulations to ensure no adverse impacts to human remains would occur in the unlikely event human remains are found.
Health and Safety Code Section 7050.5, Public Resources Code Section 5097.98, and CEQA Guidelines Section 15064.5(e) contain the mandated procedures of conduct following the discovery of human remains. According to the provisions in CEQA, if human remains are encountered at the site, all work in the immediate vicinity of the discovery shall cease and necessary steps to ensure the integrity of the 496

immediate area shall be taken. The Santa Clara County Coroner shall be notified immediately. The Coroner shall then determine whether the remains are Native American. If the Coroner determines the remains are Native American, the Coroner shall notify the Native American Heritage Commission (NAHC) within 24 hours, who would, in turn, notify the person the NAHC identifies as the Most Likely Descendant (MLD) of any human remains. Further actions shall be determined, in part, by the desires of the MLD. The MLD has 48 hours to make recommendations regarding the disposition of the remains after having been allowed access to inspect the project site. If the MLD does not make recommendations within 48 hours, the owner shall, with appropriate dignity, reinter the remains in an area of the property secure from further disturbance. Alternatively, if the owner does not accept the MLD’s recommendations, the owner or the descendent may request mediation by the NAHC. This would be included as a condition of approval of the project to ensure implementation.
Therefore, with the required statutory and regulatory procedures described above, potential impacts related to the potential discovery or disturbance of any human remains accidently unearthed during construction activities associated with the proposed project would impacts would remain consistent with the conclusions in the General Plan EIR and would be less than significant.

Energy impacts were found to be less than significant, and no mitigation measures were required.
EXISTING CONDITIONS
PG&E supplies electricity and natural gas to much of northern and central California – from Humboldt and Shasta counties in the north to Kern and Santa Barbara counties in the south – including the infrastructure for the City of Cupertino.

project site is the Monta Vista Substation on California Oak Way approximately 0.75 miles northwest of the project site. The nearest electricity transmission lines to the project site are located above the project site along Stevens Canyon Road and South Foothill Boulevard. 84 The current project site is served by both electricity and natural gas connections. Electricity is supplied to the project site via infrastructure maintained by PG&E. Silicon Valley Clean Energy (SVCE), a locally controlled public agency that has a partnership with PG&E, supplies the electricity to the project site.
SVCE provides a standard 50 percent renewable energy portfolio, in addition to a 100 percent renewable option that electricity customers can opt into. Natural gas and associated infrastructure are provided and maintained by PG&E.
Current energy demands are derived from the operation of multiple commercial uses located in the existing one-story buildings that were constructed around 1968 and 1948.85 The larger of the two existing buildings is currently occupied by neighborhood-serving restaurant, and commercial uses. However, some of the commercial spaces are currently vacant. The existing commercial building on the northern portion of the project site is currently occupied by the Cupertino Bike Shop, which specializes in bicycle parts, apparel, and accessories. The two-story residential unit is currently vacant and is used as storage by the Cupertino Bike Shop. Current energy demand includes energy demand from vehicle trips which include 454 gross average daily trips and 662 daily VMT.86
DISCUSSION
a) Would the project result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Construction activities use energy from various sources, such as on-site heavy-duty construction vehicles, vehicles hauling materials to and from the site, and motor vehicles transporting the construction crew.
The operation of the proposed commercial buildings would use energy for cooling, heating, lighting, and landscape equipment, and for vehicle trips to and from the commercial building. According to the existing trip estimates described in Section XV, Transportation, at full occupancy the proposed project would generate fewer average daily weekday vehicle trips than the existing commercial use (322 project trips compared to 454 existing trips) and less VMT (631 project daily per capita VMT compared to 850 existing daily per capita VMT).87 This is further supported by the trip estimates generated by CalEEMod described in Section II, Air Quality, which shows fewer emissions from the transportation sector when comparing the project to existing conditions.

The proposed project is an infill development project that would result in the redevelopment of the project site in a currently developed portion of the city. The project site currently has access to existing infrastructure and services; however, the proposed project would require the construction or installation of new infrastructure and capacity enhancing alterations to existing on-site facilities to connect the new residential buildings to water, stormwater, sanitary sewer, electricity, and natural gas lines. The construction of new infrastructure and capacity enhancing alterations would be necessary as part of the construction of the residential buildings and would be consistent with the design and installation of typical utility infrastructure for new mixed-use or residential buildings. Therefore, the construction or installation of new infrastructure and capacity enhancing alterations would not be a wasteful, inefficient, or unnecessary use of energy.
The proposed project would improve connectivity to existing bicycle and pedestrian facilities and locates a commercial building with neighborhood serving retail and residential uses near existing residential neighborhoods. As described in Section X, Land Use and Planning, of this Initial Study, the proposed project is consistent with the General Plan land use designation and as described in Section XII, Population and Housing, the proposed project would not result in new growth potential from what was considered in the General Plan EIR.
The proposed mixed-use and residential buildings would meet the 2019 Building and Energy Efficiency Standards of the California Public Resources Code, Title 24, Part 6, which applies to any project that is proposed to begin construction on or after August 2020. The 2019 Building Energy Efficiency Standards improve upon the 2016 Standards. The 2019 Standards require 53 percent or more energy efficiency for residential buildings, and 30 percent or more energy efficiency for non-residential buildings, respectively.
89 As described above in Chapter 3, Project Description, in Section 3.1.4.4, Utilities and Energy, the City enforces the CALGreen Building Standards, which establish planning and design standards for sustainable site development, energy efficiency (in excess of the California Energy Code requirements), in CMC Chapter 16.58, Green Building Standards Code Adopted. CMC Chapter 16.58, Section 16.58.220, Table 101.10 requires that non-residential new construction under 25,000 square feet shall achieve a minimum green building requirement of CALGreen Building Code pursuant to Chapter 5 of the California Green Building Standards Code. CMC Chapter 16.58, Section 16.58.220, Table 101.10 also requires that residential new construction exceeding nine homes shall achieve a minimum green building requirement of Green Points Rated certified at minimum 50 points, Leadership in Energy and Environmental Design (LEED) Silver, or an alternate green building standard that is as stringent as LEED or other cited standards and is subject to third party verification. Energy conserving features of the proposed project would include new landscaping that is native and/or adaptive, and drought resistant to conserve water and subsequently save energy.

GENERAL PLAN EIR
Chapter 4.5, Geology, Soils, and Seismicity, of the General Plan EIR, addressed geological and seismicrelated impacts associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Impacts were found to be less than significant, and no mitigation measures were required. The following discussion is based on project site information available in Section 4.5.1.2, Existing Conditions, of Chapter 4.5.
EXISTING CONDITIONS
The following describes the existing conditions on the project site with respect to geology and soil:
Geology. The City of Cupertino lies in the west-central part of the Santa Clara Valley, a broad, mostly flat alluvial plain that extends southward from San Francisco Bay. The site is generally flat with an average elevation of 429 feet above mean sea level and the depth of groundwater is estimated to be 25 to 30 feet below ground surface. The soil is Urban Land Flaskan Complex, which is a well-drained sandy loam, sandy clay loam, gravelly sandy clay loam and very gravelly sandy clay loam soil. 90 Surficial
geology is young, unconsolidated Quaternary alluvium,91 which is described as Holocene-age younger alluvium and coarse-grained alluvium that are composed of unconsolidated, poorly sorted gravel, silt, sand, and clay and organic matter.
Unique geologic features are those that are unique to the field of geology. Each rock unit tells a story of the natural processes operating at the time it was formed. The rocks and geologic formations exposed at the earth’s surface or revealed by drilling and excavation are our only record of that geologic history. What makes a geologic unit or feature unique can vary considerably. For example, a geologic feature may be considered unique if it is the best example of its kind and has distinctive characteristics of a geologic principle that is exclusive locally or regionally, is a key piece of geologic information important to geologic history, contains a mineral that is not known to occur elsewhere in the County, or is used as a teaching tool.
Unique geological features are not common in Cupertino. The geologic processes are generally the same as those in other parts of the state, country, and even the world. The geology and soils on the project site are common throughout the city and region and are not considered to be unique. Soils. Web-accessible soil mapping data compiled by the USDA’s Soil Conservation Survey and the California Soil Resource Laboratory hosted by University of California at Davis was used to identify the major soil types on the project site. The predominant soil types for the project site are soils of the Urban Land-Flaskan and Urban Land-Botella complexes generally formed on slopes of 2 to 9 percent. 90 California Soil Resource Lab.

In almost all instances, these soils are reportedly deep and well drained, and are typified by low runoff.92
Fault Rupture. The San Francisco Bay Area is one of the most seismically active regions in the United States. The significant earthquakes that occur in the Bay Area are generally associated with crustal movement along well-defined active fault zones such as the San Andreas Fault system. Many of these zones exhibit a regional trend to the northwest. The site is not located within a State-designated Alquist-Priolo Earthquake Fault Zone (known formerly as a Special Studies Zone) or a Santa Clara County-designated Fault Rupture Hazard Zone.93 No active fault traces are known to cross the site; however, the San Andreas Fault passes a few miles west of the city of Cupertino. Liquefaction. The site is not located within a seismically inducted liquefaction hazard zone, as mapped by the State of California and Santa Clara County. During cyclic ground shaking, such as seismic shaking during an earthquake, cyclically-induced stresses may cause increased pore water pressures within the soil matrix, resulting in liquefaction. Liquefied soil may lose shear strength that may lead to large shear deformations and/or flow failure. Liquefied soil can also settle as pore pressures dissipate following an earthquake.
Soils most susceptible to liquefaction are loose to moderately dense, saturated, non-cohesive soils with poor drainage, such as sands and silts with interbedded or capping layers of relatively low permeability soil.
Lateral Spreading. Lateral spreading typically occurs as a form of horizontal displacement of relatively flat-lying alluvial material toward an open or “free” face such as an open body of water, channel, or excavation. In soils, this movement is generally due to failure along a weak plane and may often be associated with liquefaction. As cracks develop within the weakened material, blocks of soil are displaced laterally toward the open face. Cracking and lateral movement may gradually propagate away from the face as blocks continue to break free. Because of the low potential for liquefaction, the risk of lateral spreading at the site is also considered low. Paleontological Resources. A review of the University of California’s Museum of Paleontology’s fossil locality database was conducted for the City of Cupertino. No paleontological resources have been identified on the project site; however, the presence of Pleistocene deposits that are known to contain fossils indicates that the overall city could contain paleontological resources.
DISCUSSION

on other substantial evidence of a known fault; (ii) Strong seismic ground shaking; (iii) Seismic-related ground failure, including liquefaction; (iv) Landslides, mudslides or other similar hazards? Fault Rupture
As discussed in the General Plan EIR, only one Alquist-Priolo Earthquake Fault Zone has been mapped within the City of Cupertino, namely, the zone that flanks the San Andreas Fault in the southwestern most part of the city. Because the site is not located within a State-designated Alquist-Priolo Earthquake Fault Zone or Santa Clara County-designated Fault Rupture Hazard Zone, and no active faults are known to traverse the site, the risk of surface fault rupture is considered low. The impacts from project development as they relate to surface fault rupture are considered less than significant.
Strong Seismic Ground Shaking
The hazards posed by strong seismic ground shaking during a major earthquake, while variable, are nearly omnipresent in the San Francisco Bay Area. As discussed in the General Plan EIR, in the event of a large, magnitude 6.7 or greater seismic event, much of the city is projected to experience “strong” ground shaking, with the most intense shaking forecast for the northeast part of the city where the project is located. Adherence to applicable building code, including conformance to the California Building Code (CBC) and the City’s building permit requirements would ensure that the impacts associated with strong seismic ground shaking are minimized to the maximum extent practicable. The impacts of project development as they relate to strong seismic ground shaking would be less than significant.
Liquefaction
The project site is not located within an area mapped by the State of California or Santa Clara County as having a high potential for seismically induced liquefaction. As discussed in the General Plan EIR, the potential for seismically induced liquefaction in the vicinity appears low and is limited to a very narrow strip of alluvial deposits that flank Stevens Creek approximately 0.25 miles east of the project site.
Accordingly, impacts associated with project development as they may relate to seismically induced liquefaction would be less than significant.
Landslides
The site is generally flat with elevation an average of 429 feet above mean sea level.94 The project site is not located within an area mapped by the State of California or Santa Clara County as having a high potential for seismically induced landslides. Therefore, impacts associated with project development as they may relate to seismically induced landslides would be less than significant. 94 Applied Water Resources, 2018.

b) Would the project result in substantial soil erosion or the loss of topsoil? Substantial soil erosion or loss of topsoil during construction could, in theory, undermine structures and minor slopes during development of the project site. However, compliance with existing regulatory requirements, such as the implementation of grading erosion control measures specified in Appendix J, Grading of the CBC and CMC Section 16.08.110, Interim Erosion and Sediment Control Plan, would reduce impacts from erosion and the loss of topsoil.
Examples of these control measures are best management practices such as hydroseeding or short-term biodegradable erosion control blankets; vegetated swales, silt fences, or other forms of protection at storm drain inlets; post-construction inspection of drainage structures for accumulated sediment; and post-construction clearing of debris and sediment from these structures.
Section 16.08.110 of the CMC requires the preparation and submittal of Interim Erosion and Sediment Control Plans for all projects subject to City-issued grading permits, which would minimize the removal of topsoil, avoid overly steep cut and/or fill slopes, and protect existing vegetation during grading operations.
These requirements are broadly applicable to residential development projects. Adherence to these regulations would help ensure that the impacts of project development as they relate to substantial soil erosion or loss of topsoil would be less than significant. 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?
As discussed in criterion (a), the project site is not located within an area mapped as having significant potential for seismically induced liquefaction. Because of the low potential for liquefaction, the risk of lateral spreading at the site would also be low. Therefore, the impacts of project development as they relate to liquefaction and lateral spreading would be less than significant and no mitigation measures would be required.
The site is generally flat with an average elevation of 429 feet above mean sea level.95 The properties surrounding the project site are also at a similar elevation. The impacts of project development as they relate to landslides would be less than significant.
d) Would the project be located on expansive soil, as defined by Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? Expansive soils can undergo dramatic changes in volume in response to variations in soil moisture content.
When wet, these soils can expand; conversely, when dry, they can contract or shrink. Sources of moisture that can trigger this shrink-swell phenomenon can include seasonal rainfall, landscape irrigation, utility leakage, and/or perched groundwater. Expansive soil can develop wide cracks in the dry season, and 95 Applied Water Resources, 2018.

changes in soil volume have the potential to damage concrete slabs, foundations, and pavement. Special building/structure design or soil treatment are often needed in areas with expansive soils. Expansive soils are typically very fine-grained with a high to very high percentage of clay, typically montmorillonite, smectite, or bentonite clay.
The proposed project would be subject to the CBC regulations and provisions, as adopted in CMC Chapter
16.04, Building Code, and enforced by the City during plan review prior to building permit issuance. The CBC contains specific requirements for seismic safety, excavation, foundations, retaining walls, and site demolition, and also regulates grading activities, including drainage and erosion control. Thus, compliance with existing regulations and policies would ensure that the potential future development impacts permitted under the proposed project would be reduced. Therefore, the impacts of project development as they relate to expansive soils are considered less than significant. 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 development of the proposed project would not require the construction or use of septic tanks or alternative wastewater disposal systems. Therefore, no impact would occur. f) Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
As discussed above in existing conditions, the geology and soils on the project site are common throughout the city and region and are not considered to be unique. While no paleontological resources have been identified on the project site, because the proposed project requires substantial excavation for the subterranean parking garage that could reach significant depths below the ground surface where no such excavation has previously occurred, there could be fossils of potential scientific significance that have not been recorded. Such ground-disturbing construction associated with development under the proposed project could cause damage to, or destruction of, paleontological resources. Impacts to paleontological resources would be reduced to a less-than-significant level with implementation of Mitigation Measure GEO-1, which is not a General Plan EIR mitigation measure.
Impact GEO-1: Construction of the proposed project would have the potential to directly or indirectly affect an unknown unique paleontological resource.

GENERAL PLAN EIR
Chapter 4.6, Greenhouse Gas Emissions, of the General Plan EIR, addressed the impacts from greenhouse gas emissions (GHG) associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program. GHG impacts under the General Plan EIR were found to be less than significant and no mitigation measures were required.
This section analyzes the GHG emissions from the construction and operation of the proposed project. An update to the background discussion of the GHG regulatory setting and air quality modeling in the General Plan EIR is in Appendix A, Air Quality and Greenhouse Gas Emissions, of this Initial Study.
EXISTING CONDITIONS
The existing commercial uses generate greenhouse gas emissions from transportation sources, energy (natural gas and purchased energy), and area sources such as landscaping equipment and architectural coatings. The existing land uses generate approximately 454 average daily weekday trips96 and 662 daily VMT. 97 Existing emissions based on full occupancy associated with historic operations associated with the existing commercial uses on the project site are included in Table 4-6 below. 96 TJKM Transportation Consultants.

DISCUSSION
a) Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
A project does not generate enough GHG emissions on its own to influence global climate change; therefore, this section measures the project’s contribution to the cumulative environmental impact.
Development of the proposed project would contribute to global climate change through direct and indirect emissions of GHG from transportation sources, energy use (natural gas and purchased energy), water use and wastewater generation, and solid waste generation. In addition, construction activities would generate a short-term increase in GHG emissions. The change in emissions generated by the proposed project was evaluated using the CalEEMod, Version 2016.3.25, and are shown in Table 4-7.

Construction Impacts
BAAQMD does not have thresholds of significance for construction-related GHG emissions, however, the BAAQMD advises that the lead agency should quantify and disclose GHG emissions that would occur during construction and make a determination on the significance of these construction-generated GHG emissions in relation to meeting Assembly Bill (AB) 32 GHG reduction goals. Therefore, this impact discussion applies BAAQMD’s project-level operation threshold of 660 metric tons of carbon dioxide equivalent per year (MTCO2e/year) for construction, which is based on BAAQMD’s operational-related threshold of 660 MTCO2e/year. 98 GHG emissions from construction activities are one-time, short-term emissions and, therefore, would not significantly contribute to long-term cumulative GHG emissions impacts from the proposed project. One-time, short-term emissions are converted to average annual emissions by amortizing them over the service life of a building. The total construction GHG emissions for the proposed project are estimated to be 253 MTCO2e/year (See Appendix A). For buildings in general, it is reasonable to look at a 30-year time frame, because this is a typical interval before a new building requires the first major renovation.99 As shown in Table 4-7 above, when amortized over a 30-year project lifetime, average annual construction emissions from the proposed project would represent a nominal source of GHG emissions and would not exceed BAAQMD’s operational-related threshold. Construction emissions would be less than significant, and no mitigation measures would be required.
Operational Impacts
As shown in Table 4-7 above, development of the proposed project would result in a net decrease of GHG emissions at opening year (2022). As previously described, the proposed project would generate fewer daily weekday trips and less daily VMT than the existing land uses on the project site. Because transportation emissions would generate the majority of GHG emissions associated with the proposed project, this reduction in daily trips and VMT would provide a project benefit in reducing GHG emissions.
Additionally, the new buildings would be more energy efficient than the existing structures and would be built to achieve the latest Title 24 Building and Energy Efficiency Standards. Operation of the proposed project would result in a net decrease in GHG emissions and would not exceed the BAAQMD bright-line screening threshold of 660 MTCO2e.100 Because long-term GHG emissions associated with the proposed project are anticipated to decrease, resulting in a project benefit to GHGs, no impact would occur. 98 California Executive Order B-30-15 requires the state to reduce GHG emission 40% below 1990 levels by 2030. A 40% reduction from BAAQMD’s 1,100 MTCO2e/year threshold identified in the Bay Area Air Quality Management District, 2017, California Environmental Quality Act Air Quality Guidelines, p.2-4, is 660 MTCO2e/per year. 99 International Energy Agency, 2008, Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings, March. While the BAAQMD CEQA Guidelines do not provide specific criteria in evaluating construction-related GHG emissions impacts, this methodology is consistent with the methodology utilized by the South Coast Air Quality Management District. 100 California Executive Order B-30-15 requires the state to reduce GHG emission 40% below 1990 levels by 2030. A 40% reduction from BAAQMD’s 1,100 MTCO2e/year threshold identified in the Bay Area Air Quality Management District, 2017, California Environmental Quality Act Air Quality Guidelines, p.2-4, is 660 MTCO2e/per year. 508

b) Would the project conflict with an applicable plan, policy, or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases?
Applicable plans adopted for the purpose of reducing GHG emissions include the CARB Scoping Plan, the MTC’s/ ABAG’s Plan Bay Area 2040, and Cupertino’s Climate Action Plan. A consistency analysis with these plans is presented below.
CARB’s Scoping Plan
In accordance with AB 32 and SB 32 the CARB 2017 Climate Change Scoping Plan101 (Scoping Plan) contains the State’s strategy to achieve 1990 level emissions by year 2020 and a 40 percent reduction from 1990 emissions by year 2030. The Scoping Plan is applicable to State agencies and is not directly applicable to cities/counties and individual projects. Nevertheless, the Scoping Plan has been the primary tool that is used to develop performance-based and efficiency-based CEQA criteria and GHG reduction targets for climate action planning efforts.
Statewide strategies to reduce GHG emissions in the latest Scoping Plan (2017) include implementing SB 350, which expands the Renewables Portfolio Standard to 50 percent by 2030 and doubles energy efficiency savings; expanding the Low Carbon Fuel Standard to 18 percent by 2030; implementing the Mobile Source Strategy to deploy zero-electric vehicle buses and trucks; implementation of the Sustainable Freight Action Plan; implementation of the Short-Lived Climate Pollutant Reduction Strategy, which reduces methane and hydrofluorocarbons 40 percent below 2013 levels by 2030 and black carbon emissions 50 percent below 2013 levels by 2030; continuing to implement Senate Bill 375; creation of a post-2020 Cap-and-Trade Program; and development of an Integrated Natural and Working Lands Action Plan to secure California’s land base as a net carbon sink. Statewide GHG emissions reduction measures that are being implemented as a result of the Scoping Plan would reduce the proposed project’s GHG emissions.
The proposed project would be constructed to achieve the standards in effect at the time of development and would not conflict with statewide programs adopted for the purpose of reducing GHG emissions. As stated above, while the measures in the State’s Scoping Plan are not directly applicable to individual development projects, the project’s GHG emissions would be reduced through compliance with statewide measures that have been adopted since AB 32 and SB 32 were adopted. Therefore, the impact would be less than significant.
MTC’s/ABAG’s Plan Bay Area
Plan Bay Area 2040 is the Bay Area’s Regional Transportation Plan (RTP)/Sustainable Community Strategy (SCS). To achieve MTC’s/ABAG’s sustainable vision for the Bay Area, the Plan Bay Area 2040 land use concept plan for the region concentrates the majority of new population and employment growth in the region in Priority Development Areas (PDAs). PDAs are transit-oriented, infill development opportunity areas within existing communities. An overarching goal of the regional plan is to concentrate development 101 Note that the 2017 Climate Change Scoping Plan is an update to the 2008 and 2014 Scoping Plans. 509

in areas where there are existing services and infrastructure rather than allocate new growth to outlying areas where substantial transportation investments would be necessary to achieve the per capita passenger vehicle, vehicle miles traveled, and associated GHG emissions reductions. Although the proposed project is not within a PDA, as discussed in Section XII, Population and Housing, growth associated with the proposed project is consistent with ABAG projections and would not exceed regional population and employment projections (see Chapter 4, General Plan EIR Consistency Analysis, of this Initial Study). The proposed project is an infill development project that would result in an increase in land use intensity in a portion of the city that has access to existing infrastructure and services, including transit service (see Section XV, Transportation). Therefore, the proposed project would not conflict with the land use concept plan for the City of Cupertino identified in the Plan Bay Area 2040 and the impact would be less than significant.
City of Cupertino Climate Action Plan
The Cupertino Climate Action Plan (CAP) is a strategic planning document that identifies sources of GHG emissions within the city’s boundaries, presents current and future emissions estimates, identifies a GHG reduction target for future years, and presents strategic goals, measures, and actions to reduce emissions from the energy, transportation and land use, water, solid waste, and green infrastructure sectors.
The emissions reduction strategies developed by the City followed the BAAQMD’s CEQA Guidelines (2011) and the corresponding criteria for a Qualified Greenhouse Gas Emissions Reduction Program as defined by the BAAQMD, which in turn were developed to comply with the requirements of AB 32 and achieve the goals of CARB’s 2008 Scoping Plan. Since the adoption of the CAP in January of 2015, the Legislature adopted SB 32 (September 2016) and CARB adopted the 2017 Climate Change Scoping Plan (December 2017), aimed at meeting SB 32’s GHG reduction goal of 40 percent below 1990 levels by 2030.
Qualified GHG Reduction Strategy
A qualified GHG reduction strategy adopted by a local jurisdiction should include the following elements, described in the State CEQA Guidelines Section 15183.5. BAAQMD’s revised CEQA Guidelines provides the methodology to determine if a GHG reduction strategy meets these requirements. The following includes a description of the BAAQMD methodology and how the Cupertino CAP meets the requirement.
1. Quantify GHG emissions, both existing and projected over a specified time period, resulting from activities within a defined geographic area.
Cupertino’s CAP identifies a baseline GHG emissions inventory for year 2010 and business-asusual forecasts for 2020, 2035, and 2050 for land uses within the City.
Establish a level, based on substantial evidence, below which the contribution to greenhouse gas emissions from activities covered by the plan would not be cumulatively considerable. Cupertino’s CAP has established a goal (or level) of 15 percent below 2005 levels by 2020 and 35 percent below 2005 levels by 2035. The 2020 GHG reduction goal is in line with AB 32. However, the 2030 goal was adopted prior to SB 32.

Identify and analyze the GHG emissions resulting from specific actions or categories of actions anticipated within the geographic area.
The GHG emissions sources calculated in the baseline GHG emissions inventory include commercial, residential, and industrial electricity and natural gas use, on-road transportation, solid waste disposal, energy use related to water and wastewater, agricultural off-road equipment and emissions associated with fertilizer application, and off-road equipment use for construction and lawn and garden activities. GHG emissions from these activities were calculated from activity data such as kilowatt hours of electricity, therms of natural gas, tons of waste disposed, and vehicle miles traveled from trips with an origin or destination in Cupertino.
Specify measures or a group of measures, including performance standards, that substantial evidence demonstrates, if implemented on a project-by-project basis, would collectively achieve the specified emissions level.
The Cupertino CAP has identified groups of measures and performance standards aimed at achieving these targets: Reduce Energy Use/Improve Facilities; Encourage Alternative Transportation/Convert Vehicle Fleet; Conserve Potable Water; Reduce Solid Waste; and Expand Green Infrastructure. The Cupertino CAP strategies achieve the near-term (i.e., 2020) GHG reduction target. Strategies for the post-2020 targets were not quantified.
Establish a mechanism to monitor the plan’s progress toward achieving the target GHG emissions level and to require amendment if the plan is not achieving specified levels. The City has a sustainability division that implements and tracks the City’s GHG reduction strategies and progress toward GHG reduction targets. The City’s sustainability division prepares annual reports on CAP implementation and progress as part of the monitoring program, including projects and policies, data and metrics, as well as inventory updates to determine if the CAP is achieving its targeted goals.
Be adopted in a public process following environmental review. The City’s 2015 addendum to General Plan EIR102 demonstrated that that adoption of the Cupertino CAP would not create any new or substantially more severe significant effects on the environment that were not analyzed in the General Plan EIR certified in 2014.103 Based on the analysis above, the City’s CAP is a qualified GHG reduction plan for the AB 32 targets.
In addition, a specific project proposal is considered consistent with the Cupertino CAP if it does not conflict with the required GHG reduction measures contained in the adopted CAP. Project consistency with the adopted GHG reduction measures are shown in Table 4-8:

Development in Cupertino, including the proposed project, is required to adhere to City-adopted policy provisions, including those contained in the adopted CAP. The City ensures that the provisions of the Cupertino CAP are incorporated into projects and permits as part of development review and through conditions of approval. In general, the proposed project represents a benefit to GHG emissions compared to existing conditions because the mixed-use and infill development would locate housing and residential serving land uses in an existing neighborhood and would replace the older structures with newer, more energy efficient structures that achieve the 2019 Building and Energy Efficiency Standards and water efficiency standards and would decrease GHG emissions by 26.5 percent. Therefore, the impact would be less than significant.

Chapter 4.7, Hazards and Hazardous Materials, of the General Plan EIR, addressed the hazards- and hazardous materials-related impacts associated with buildout of the General Plan including the redevelopment of the project site with up to 27 dwelling units and a 30-foot height maximum at a program level. Impacts were found to be less than significant with mitigation measures to reduce impacts from development on sites with known hazardous contamination. General Plan EIR Mitigation Measures HAZ-4a and HAZ-4b, previously adopted and incorporated into the General Plan, are required to be implemented for sites with known contamination and potential residual contamination. As discussed in Chapter 4.7, the project site is not listed as a site with known contamination or potential residual contamination; therefore, the identified mitigation measures in the General Plan EIR do not apply to the proposed project.
The following is a summary of Section, 4.7.1.2, Existing Conditions, of Chapter 4.7, and project specific information from the Phase I Environmental Site Assessment (ESA) dated January 12, 2019, prepared for the project site by Applied Water Resources Corporation and reviewed by PlaceWorks and the City.
EXISTING CONDITIONS
Phase I ESA
The purpose of the Phase I ESA was to identify any recognized environmental conditions (RECs) associated with the presence of hazardous substances or petroleum products in the vicinity of the project site. The Phase I ESA included a review of federal, State, tribal, and local databases, site reconnaissance, and a review of historical sources. The assessment revealed no indications of RECs on the project site.104 The site was used for orchards and associated buildings in 1939. The orchards were removed in 1948.
According to the Department of Toxic Substance Control (DTSC), when orchards have been removed or became inactive prior to 1950, organic pesticides are not an issue warranting further testing.105 Following the removal of the orchards, the project site was developed with the existing smaller mixed-use building 104 Applied Water Resources, 2018.

located on the site, currently used as the Cupertino Bike Shop. The larger building on the site, currently used for a variety of commercial uses, was constructed by 1963.106 The Cupertino Bike Shop located on the site is known to use approximately 75 to 100 gallons of aqueous parts cleaner per year, which is considered hazardous waste. However, the Phase I ESA describes the materials as being used appropriately and no indications of spills, releases, or violations were noted in the Phase I ESA.107
The search of the DTSC’s EnviroStor Database and the GeoTracker database search did not reveal any hazardous materials or leaking underground storage tanks also referred to as “LUST” sites on the project site.108,109 According to GeoTracker, there is a completed/closed soil contamination site approximately 500 feet to the northeast of the project site at a residential property. There is also one completed/closed voluntary cleanup site 0.5 miles to the northeast of the project site at the Blackberry Farm Play Area.110 Lead-Based Paints and Asbestos-Containing Materials
Based on the age of the buildings, there is a potential for asbestos-containing materials (ACM) and leadbased paint (LBP), which were not regulated in construction until the early 1970’s. Neither ACM or LBP are known to have been used during construction of the existing structures.111 ACMs and LBPs do not qualify as RECs regulated by the DTSC.112

Bay Area Retirement Community approximately 0.75 miles to the north, and Cupertino Senior Center approximately 1.5 miles to the northeast.
Airports
The nearest public airports are San José International Airport, approximately 8.5 miles to the northeast, and Palo Alto Airport, approximately 10 miles to the north. The nearest heliports are McCandless Towers Heliport, approximately 7 miles to the northeast, and County Medical Center Heliport, approximately 7.5 miles to the east. The nearest private (military/corporate) airport is Moffett Federal Airfield, approximately 7 miles to the north. The project site is not within the boundaries of an airport land use plan.
Wildfire
The California Department of Forestry and Fire Protection (CAL FIRE) has designated the project site as a Local Responsibility Area (LRA) and a non-very high fire hazard severity zone. The project site is near lands that CAL FIRE designates as State Responsibility Area (SRA), which are areas of the state where the State of California is financially responsible for the prevention and suppression of wildfires. SRA’s do not include lands within city boundaries or in federal ownership. The SRA is approximately 0.5 miles to the west of the project site.113 The project site is located within the wildland-urban interface, which is an area of transition between wildland (unoccupied land) and land with human development (occupied land).114
DISCUSSION
a) Would the project create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials?
Construction Impacts
Construction activities at the project site would involve the use of larger amounts of hazardous materials than would operation of the proposed project, such as petroleum-based fuels for maintenance and construction equipment, and coatings used in construction, which would be transported to the site periodically by vehicle and would be present temporarily during construction. These potentially hazardous materials would not be of a type or occur in sufficient quantities to pose a significant hazard to public health and safety or the environment, and their use during construction would be short-term. As with proposed project operation, the use, transport, and disposal of construction-related hazardous materials would be required to conform to existing laws and regulations. Compliance with applicable laws and regulations governing the use, storage, and transportation of hazardous materials would ensure that all potentially hazardous materials are used and handled in an appropriate manner, and would minimize the potential for safety impacts to occur. Consequently, associated impacts from construction of the proposed project would be less than significant.

Operational Impacts
The proposed mixed-use development would not involve the routine transport or disposal of hazardous materials. Project operation would involve the use of small amounts of hazardous materials for cleaning and maintenance purposes, such as cleansers, degreasers, pesticides, and fertilizers. These potentially hazardous materials would not be of a type or be present in sufficient quantities to pose a significant hazard to public health and safety or the environment. Furthermore, such substances would be used, transported, stored, and disposed of in accordance with applicable federal, State, and local laws, policies, and regulations. Any businesses that transport, generate, use, and/or dispose of hazardous materials in Cupertino are subject to existing hazardous materials regulations, such as those implemented by Santa Clara County Department of Environmental Health Hazardous Materials Compliance Division, and hazardous materials permits from the Santa Clara Fire Department (SCCFD). The SCCFD also conducts inspections for fire safety and hazardous materials management of businesses and multi-family dwellings, in accordance with the City of Cupertino Hazardous Materials Storage Ordinance in Title 9, Health and Sanitation, Chapter 9.12, Hazardous Materials Storage. Thus, associated impacts from the operational phase of the project would be less than significant.
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?
As described under criterion (a), above, construction and operation of the proposed project would involve the storage and use of common cleaning substances, building maintenance products, paints, and solvents, as well as petroleum-based fuels for maintenance and construction equipment, and coatings used in construction. As described in the existing conditions, the existing buildings were developed in 1948 and 1963, and the Phase I ESA identified that, although all suspect ACMs and LBP are in good condition and do not currently pose a health or safety concern, the demolition of the buildings could release these hazardous materials. An impact could occur if construction and operation of the proposed project creates conditions where these hazardous materials could easily contaminate surrounding soil, water, or air. The most likely scenarios would be from rainwater runoff spreading contaminated waste. Stormwater runoff is discussed in Section IX, Hydrology and Water Quality, of this Initial Study and impacts were found to be less than significant.
Construction Impacts
Similar to the operation of the proposed project, the types of construction materials and equipment would be considered standard for this type of development. All spills or leakage of petroleum products during construction activities are required to be immediately contained, the hazardous material identified, and the material remediated in compliance with applicable State and local regulations. All contaminated waste would be required to be collected and disposed of at an appropriately licensed disposal or treatment facility. Furthermore, strict adherence to all emergency response plan requirements set forth by the Santa Clara County Department of Environmental Health Hazardous Materials Compliance Division 519

would be required through the duration of the construction of each individual development project.115 Therefore, substantial hazards to the public or the environment arising from the routine use of hazardous materials during project construction would not occur.
While the Phase I ESA identifies the potential for ACMs and LBPs on the project site, removal of these types of hazardous materials would require licensed contractors to remove and handle these materials in accordance with existing federal, State, and local regulations. These regulations include the USEPA’s National Emission Standards for Hazardous Air Pollutants (Code of Federal Regulation Part 61), Bay Area Air Quality Management District’s Regulation 11, Title 8 of the California Codes of Regulations, the Unified Program, and the City’s General Plan Health and Safety Element Policy HS-6.1, which would insure that risks associated with the transport, storage, use, and disposal of such materials would be reduced to the maximum extent practical. Consequently, associated impacts from demolition phase of the project would be less than significant and no mitigation measures are required.
Operational Impacts
The proposed mixed-use development is not considered the type of project that would create a hazardous materials threat to the users of the site or the surrounding land uses. The Santa Clara County Hazardous Materials Compliance Division (HMCD) is the Certified Unified Program Agency (CUPA) for Santa Clara County including the City of Cupertino and is responsible for enforcing Chapter 6.95 of the California Health and Safety Code. As the CUPA, Santa Clara County HMCD is required to regulate hazardous materials business plans (HMBP) and chemical inventory, hazardous waste and tiered permitting, underground storage tanks, and risk-management plans. The HMBP is required to contain basic information on the location, type, quantity, and health risks of hazardous materials stored, used, or disposed of on development sites. The HMBP also contains an emergency-response plan, which describes the procedures for mitigating a hazardous release, procedures and equipment for minimizing the potential damage of a hazardous materials release, and provisions for immediate notification of the California Emergency Management Agency and other emergency-response personnel, such as the SCCFD.
