1. Introduction
This section describes the standards for determining a significant effect on the environment from construction and operation of the proposed Idlewild Townhomes Project (proposed project) pursuant to the requirements of the California Environmental Quality Act (CEQA) .1 Additionally, this section describes the standards in the City of Cupertino Municipal Code (CMC) Chapter 17.04, Cupertino Standard Environmental Protection Requirements, that apply to all projects in Cupertino.

1.1 CATEGORICAL EXEMPTION
Article 19 (Categorical Exemptions) of the CEQA Guidelines 2 includes, as required by CEQA Section 21084 (List of Exempt Classes of Projects; Projects Damaging Scenic Resources), a list of classes of projects that have been determined not to have a significant effect on the environment and, as a result, are exempt from review under CEQA. This document has been prepared to demonstrate CEQA compliance as it pertains to the redevelopment of the existing commercial development on the project site into the proposed 59-unit townhome development, herein referred to as the proposed project . This document also provides information to decision makers regarding a finding that the proposed project is exempt under CEQA.

This document describes how the proposed project qualifies for a Class 32 CEQA Exemption pursuant to CEQA Guidelines Section 15332 (Infill Development Projects), which requires that:
(a) The proposed project is consistent with the applicable General Plan designation and all applicable General Plan policies, as well as the applicable Zoning designations and regulations; (b) The proposed project would occur within the c ity limits on a site of less than 5 acres in size that is substantially surrounded by urban uses;
(c) The project site has no value for endangered, rare or threatened species; (d) The proposed project would not result in any significant effects related to traffic, noise, air quality or water quality; and
(e) The project site can be adequately served by all required utilities and public services.

1 The CEQA Statute is found at Public Resources Code, Division 13, Environmental Quality, Sections 21000 to 21189. 2 The CEQA Guidelines are found at California Code of Regulations, Title 14, Natural Resources, Division 6, Resources Agency, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act, Sections 15000 to 15387.

In addition, this document demonstrates that none of the exceptions to categorical exemptions apply pursuant to CEQA Guidelines Section 15300.2 (Exceptions), which are based on the following:
(a) The project is not located within a sensitive environment; (b) There would be no cumulative impacts;
(c) There would be no significant effects on the environment due to an unusual circumstance; (d) There would be no impacts to a scenic highway;
(e) The project site is not located on a hazardous waste site; and (f) There would be no impacts to historical resources.

1.2 STANDARD ENVIRONMENTAL PROTECTION REQUIREMENTS
In addition to the standards identified in Section 1.1, Categorical Exemption, all projects in Cupertino are required to comply with the CMC Chapter 17.04, Standard Environmental Protection Requirements.

Pursuant to CMC Section 17.04.030(A), the se requirements apply to every project in the city. Pursuant to CMC Section 17.04.030(B)(1), because the proposed residential townhome project has more than four units, compliance must be demonstrated through submittal and implementation of a construction management plan and/or permit plans, as applicable, prior to issuance of a discretionary approval, to the satisfaction of the City. Pursuant to CMC Chapter 17.04, development projects must submit technical reports for air quality, hazardous materials, vehicle miles traveled (VMT), and construction vibration. These reports are subject to peer review by the City’s third-party reviewers. This chapter of the CMC also includes nine permit submittal requirements:

1. Air Quality

2. Hazardous Materials

3. Greenhouse Gas Emissions and Energy

4. Biologic Resources

5. Cultural Resources

6. Hydrology and Water Quality

7. Noise and Vibration

8. Paleontological Resources

9. Utilities and Service Systems

2. Project Description

2.1 REGIONAL LOCATION
The project site is in the city of Cupertino, approximately 38 miles southeast of San Francisco. Cupertino is on the western edge of Santa Clara County and west of the city of San Jose, south of the city of Sunnyvale, and north of the city of Saratoga. Regional access to the project site is provided by Interstate 280 (I-280) via North Wolfe Road to the north, and by Highway 85 via Stevens Creek Boulevard to the west. See Figure 2 - 1, Regional and Vicinity Map.

2.2 PROJECT SITE

2.2.1 Location
The 2.72-acre project site at 10065 East Estates Drive3 in the central region of the city near the intersection of Stevens Creek Boulevard and Wolfe Road . The project site is within a Santa Clara Valley Transportation Authority (VTA) City Cores, Corridors, and Station Areas Priority Development Area (PDA) 4 and within a Transit Priority Area (TPA)5 as defined by the Association of Bay Area Governments (ABAG) and Metropolitan Transportation Commission (MTC). As shown on Figure 2-2, Aerial View of Project Site and Surroundings, the project site is in a built -up and urbanized area in the vicinity of the Marketplace shopping mall and a private educational institution to the west and southwest, undeveloped land to the north, commercial uses to the east, and single -family residences to the south. The project site is bounded by Stevens Creek Boulevard to the north, East Estates Drive to the east, Richwood Drive to the south, a daycare to the southwest, and commercial buildings and surface parking lot to the west.

Sensitive receptors include places with people that have an increased sensitivity to air pollution, noise, or environmental contaminants. These sites can include schools, parks and playgrounds, day care centers, hotels, senior housing, nursing homes, hospi tals, and residential dwelling units. Sensitive receptors within

0.25 miles (1,320 feet)6 of the project site include the following:
 Residential single-family units across Richwood Drive approximately 0.01 miles (60 feet) to the south;  Daycare centers approximately 0.01 miles (40 feet) immediately southwest, 0.07 miles (380 feet) southeast, and 0.22 miles (1,140 feet) northwest;
 Medical buildings (dentist and orthodontist) approximately 0.03 miles (175 feet) east and medical clinics approximately 0.07 miles (350 feet) northeast and east;  Wilson Park approximately 0.19 miles (1,010 feet) southwest and Main Street Park approximately 0.22 miles (1,150 feet) northeast;
 Bethel Lutheran Church approximately 0.22 miles (1,180 feet) southeast.

2.2.2 Existing Site Conditions
As shown on Figure 2-2, the project site is currently developed with a commercial building. The project site also currently includes a parking lot associated with the commercial building.

The project site is relatively flat with an elevation of approximately 200 feet above mean sea level. 7 The
surficial geology consists of late Pleistocene older surficial sediments, which is described as older alluvial terrace gravel, sand, and clay, undeformed. 8 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. 9 Unique geological
features are not common in Cupertino. The geology and soils on the project site are common throughout the city and region and are not considered to be unique.

The Phase I Environmental Site Assessment (ESA) conducted for the proposed project determined that the project site was used for agricultural purposes as orchards from 1939 through the late 1960s. 10 Between 1956 and 1960, the orchards were felled, and the project site was redeveloped with the existing commercial

6 This distance is consistent with CEQA Guidelines topic Hazards and Hazardous Materials, which asks “Would the project emit hazardous emissions or handle hazardous materials, substances or waste within 0.25 miles of an existing or proposed school?”

building and parking areas. One Hour Dry Cleaners operated a dry-cleaning business at 10045 East Estates Drive using tetrachloroethylene (PCE) as a dry-cleaning solvent between the 1960s and 2010, when the dry- cleaning operation converted to using a hydrocarbon-based solvent.

Due to the presence of PCE, believed to be associated with the former dry-cleaning operations, in soil and soil gas, the project site is listed as an open cleanup program site (case ID 2023-17s) under the oversight of Santa Clara County Department of Environmental Health (SCCDEH) and is listed on the State Water Quality Control Board’s GeoTracker website.11 Several soil, groundwater, soil gas, indoor air, and sub-slab soil gas investigations have been conducted to delineate the lateral and vertical extents of the plume and determine the human health risks to building occupants. The majority of the PCE is present within the back alley behind the former One Hour Cleaners tenant space and impacts only soil and soil gas. The plume extends westerly to the off-site property to the west.

The property owner entered into a voluntary remedial action agreement with SCCDEH in July 2023. A Remedial Action Plan was prepared for the proposed project in September 2023, which involved installing a soil vapor extraction (SVE) system to reduce the concentrations of PCE and its breakdown products in the subsurface to a level that is acceptable for residential occupancy. The SVE system was operated from June 2024 until January 2025, when the system was shut off to undergo rebound testing and determine if there was remaining PCE mass remaining in the subsurface. Based on the rebound testing results, the SVE system will be reactivated and an additional SVE extraction well will be added to the network.

The Phase I ESA identified the following Recognized Environmental Condition (REC) and (future) controlled REC at the project site:
12  REC: Former One Hour Cleaners PCE releases . Discharges of PCE from former dry cleaning operations have impacted the project site and off site property to the west. PCE is present in soil gas and to a lesser degree, soil, at concentrations exceeding residential and/or commercial Environmental Screening Levels (ESLs).
 Future Controlled REC: Institutional Controls/Deed Restrictions. Institutional Controls (IC) will be required following successful completion of SVE. ICs will likely include an access agreement to allow SCCDEH personnel on the project site at any time; funding for SCCDEH oversight; and operation maintenance and monitoring (OM&M) and reporting for the vapor mitigation system that is expected to be installed under the proposed project. A corresponding deed restriction would be recorded for the project site to ensure the systems remain operational. When approved, the ICs/deed restriction will represent a controlled REC.

An inspection for asbestos containing materials (ACMs) and lead based paint (LBP) was performed and identified the presence of ACMs within the existing building.13 Based on current occupancy, a full inspection for asbestos in the shopping center was not feasible. The flooring, insulation, ceiling riles, wallboard, roofing, among other suspect ACMs may require additional inspection/testing and an abatement plan will be required to address ACMs.

The existing building on the project site is not currently listed on the National Register of Historic Places 14 or the list of California Historical resources,15 nor is it associated with significant cultural events, persons in California’s past, and does not have any distinctive historical characteristics, and as such does not have any qualifying historical value.

According to the Vegetation Map shown in the Environmental Resources and Sustainability Element of the Cupertino General Plan, the project site is within the urban forest (i.e., trees in the city). 16 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. 17 There is currently no landscaping on-site.

The project site is in a Local Responsibility Area (LRA) but is not located within a fire hazard severity zone as designated by California Department of Forestry and Fire Protection (CAL FIRE). It is located approximately

3.2 miles northeast of a very high fire hazard severity zone in an LRA, and 2.6 miles east of lands that CAL FIRE designates as a high fire hazard severity zone in a State Responsibility Area (SRA). 18 The project site is located roughly 2.6 miles northeast of a wildland urban interface (WUI), which is an area of transition between wildland (unoccupied land) and land with human development (occupied land).19

IDLEWILD TOWNHOMES PROJECT CEQA EXEMPTION

CITY OF CUPERTINO

2. Project Description

2.3 LAND USE AND ZONING DESIGNATIONS
The project site is assigned Assessor’s Parcel Numbers (APN) 369-06-002, 369-06-003, and 369-06-004.

While the City was in the process of obtaining certification of its (2023 -2031) Housing Element by the California Department of Housing and Community Development , the developer submitted a preliminary application pursuant to the Housing Crisis Act of 2019, commonly referred to by its legislative number, Senate Bill (SB) 330. SB 330 vests the standards that are in place at the time a “preliminary application” for a housing project is submitted and prevents jurisdictions from imposing or enforcing new design standards on housing projects that are not objective. As such, the project is subject to the regulations in place at the time of the preliminary application was submitted on February 7, 2024. 20 See density standards below.

The project site is within the Heart of the City Special Area with a Commercial/Residential Very High Density General Plan land use designation, and the Planned Development with General Commercial with Multi- Family Residential (P(CG, R-4)) zoning district at the time of application. The Commercial/Residential Very High Density land use designation allows mixed-use development with commercial uses and an established maximum residential density of up to 50 dwelling units per acre. 21 The Heart of the City Specific Plan
(Specific Plan) contemplates mixed -use development with a primary focus on providing commercial uses that serve the public with frontages of buildings along Stevens Creek Boulevard. On sites with a mixed-use residential designation, residential is a permitted use only on Housing Element sites. The applicable standards in the General Plan allow for a maximum building height of 45 feet on the project site.

The general type of use allowed on the project site is General Commercial with Multi- Family Residential (P(CG, R-4)), which allows for residential uses. All planned development districts are identified on the zoning map with the letter code "P" followed by a specific reference to the general type of use allowed in the particular planning development zoning district. As described in CMC Section 19.80.010, Purpose, the planned development zoning district is intended to provide a means of guiding land developm ent 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, topographi cal considerations, and community design objectives. The planned development zoning district is intended to:
 Encourage variety in the development pattern of the community.  Promote a more desirable living environment.
 Encourage creative approaches in land development.

20 At the time of the preliminary Senate Bill 330 application, the project site was zoned as Planned Development with General Commercial and Residential (P(CG, Res)) with a density 25 dwelling units per acre and a height limit of 45 feet. 21 City of Cupertino, May 2024, Cupertino General Plan Community Vision 2015-2040, Appendix A: Land Use Definitions, https://www.cupertino.gov/Your-City/Departments/Community-Development/Planning/General-Plan/General-Plan-Community- Vision, accessed March 18, 2025.

 Provide a means of reducing the amount of improvements required in development through better design and land planning.
 Conserve natural features.
 Facilitate a more aesthetic and efficient use of open spaces.  Encourage the creation of public or private common open space.

Pursuant to the State Density Bonus Law (Government Code Section 65915) and the City’s Density Bonus ordinance (CMC Chapter 19.56, Density Bonus) , the project applicant has requested the following, to the extent needed to comply with applicable objective standards:
 A waiver or reduction of development standards to reduce the front, side, and rear setbacks for portions of the project.
 A waiver or reduction of development standards to increase the maximum lot coverage from 40 percent to 42.4 percent.
 A waiver to the Heart of the City Specific Plan Design Guidelines for Common Open Space.  A waiver for the Heart of the City retail requirement to allow for residential-only use.  A reduction of vehicle parking standards pursuant to Government Code Section 65915(p).

2.4 PROPOSED PROJECT
The project applicant, Toll Brothers, is proposing the Idlewild Townhomes Development Project that would involve the demolition of the existing commercial building (approximately 35,170 square feet) and the construction of 55 townhome units and 10 accessory dwelling units (ADUs). The following provides a detailed description of the proposed project as shown on the conceptual site plan dated July 2024.22

2.4.1 Proposed Townhomes
The proposed townhomes would include 43 market-rate units and 12 below-market-rate units for a total of 55 townhome units, as well as 10 ADUs. There are several different townhome types proposed, including two-, three-, and four-bedroom units, ranging from 1,442 square feet to 2,295 square feet. Each townhome would have three stories with a roof deck and would be approximately 43 feet tall at the highest point. Each townhome would include private open space through a porch, roof deck, and balcony, averaging approximately 396 square feet per unit. The proposed project includes 110 off -street garage residential parking spaces and 9 guest uncovered parking spaces. Each unit will have an attached private two -car garage. Bicycle storage for residents is provided in the private garages. The proposed project would provide

IDLEWILD TOWNHOMES PROJECT CEQA EXEMPTION

CITY OF CUPERTINO

2. Project Description

1,140 square feet of common usable open space. The proposed project site plan is shown on Figure 2-3, Proposed Site Plan.

2.4.2 Landscaping
Groundcover, shrubs, and trees would be planted throughout the site. T he total landscape area would be 3,745 square feet. Groundcovers and shrubs proposed on site would be of the Agave, Aloe, Anigozanthus, Arctostaphylos, Bulbine, Calandrinia, Carpenteria, Cistus, Dianella, Dietes, Dodonea, Echeveria, Eremophila, Epilobium, Erigonum, Euphorbia, Galvezia, Grevillea, Festuca, Hemerocallis, Hesperaloe, Heurchera, Lirope, Lomandra, Myrsine, Myrtus, Muhlenbergia, Nandina, Pennisetum, Pittosporum, Polystichum, Prunus, Rhaphiolepis, Rosmarinus, Salvia, Senecio, Sesleria, Teucrium, and Yucca genera. The proposed project
would plant 93 trees on-site and off-site, including 18 street trees to replace the 9 existing trees off-site along East Estates Drive and Richwood Drive to be removed. Trees proposed as part of the plant palette include Acer, Agonis, Cercis, Chionanthus, Chitalpa, Geijera Lagerstroemia, Laurus, Magnolia, Olea, Podocarpus, Prunus, Quercus, Rhaphiolepis, Styrax, and Zelkova genera. The street trees proposed along East Estates Drive and Richwood Drive would be Wireless Zelkova (Zelkova serrata 'Schmidtlow') trees.

2.4.3 Project Access and Circulation

2.4.3.1 VEHICULAR ACCESS
The proposed project would have a two-lane entrance/exit circulation pattern with the access point on East Estates Drive. The proposed emergency and garbage pick -up access route would be the same as the proposed vehicle access routes.

As stated in Section 2.2.1, Location, the project site is within a TPA and meets the standard for a major transit stop.23 The closest bus stop to the project site is approximately 0.02 miles (115 feet) away, on the north side of Stevens Creek Boulevard. The nearest transit stop is located 0.05 miles (280 feet) away, on the west side of Miller Avenue, which provides stops with a bus frequency of service interval of 15 to 20 minutes during the peak weekday commute periods along VTA bus route 23 and Rapid Transit 523. In addition, VTA bus routes 25, 51, and 55 have a bus frequency of every 30 minutes or less. The project was reviewed by VTA and no improvements to the stops were requested.

23 Public Resources Code Section 21099 states that a transit priority area means an area within one-half mile of a ‘major transit stop’ that is existing or planned, if the planned stop is scheduled to be completed within the planning horizon included in a Transportation Improvement Program or applicable regional transportation plan, and Section 21064.3 states that a ‘major transit stop’ is a site containing an existing rail transit station, a ferry terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 20 minutes or less during the morning and afternoon peak commute periods. Note that Section 21064.3 was amended in 2024 and the change from 15 minutes to 20 minutes went into effect on January 1, 2025; however, the Cupertino Municipal Code Section 17.08.010, Definitions, includes the now outdated standard of 15 minutes.

IDLEWILD TOWNHOMES PROJECT CEQA EXEMPTION

CITY OF CUPERTINO

2. Project Description

2.4.3.2 PEDESTRIAN AND BICYCLE ACCESS
Pedestrian access to the townhomes would be available from the access point along East Estates Drive. The proposed development provides interior pedestrian circulation throughout the site. While the proposed project does not propose any new bicycle lanes or routes, the project site is accessible via the existing Enhanced Bike Lane on Stevens Creek Boulevard.24

2.4.4 Utilities and Public Services Providers
The proposed utility infrastructure would connect to the existing water, sewer, storm drain system, and electricity network in the area, and would be served by an existing solid waste landfill.

2.4.4.1 WATER SUPPLY AND CONSERVATION
The project site is located within the Cupertino Water Service (CWS) area, leased to San José Water (SJW).

Water service to the project site would be provided by the existing water line via an 8-inch pipe on Stevens Creek Boulevard and a 6-inch pipe on East Estates Drive. No new connections would be needed and are not proposed as part of the project.

The proposed project incorporates a number of features meant to conserve water . The proposed landscaping would include native and/or adaptive, and drought resistant plant materials of similar water use grouped by hydrozones. The majority of plantings would be drought tolerant grasses, shrubs, and trees that once established, would be adapted to a dry summer and intermittent rain in the winter season. All planting and irrigation would conform with the Cupertino Landscape Ordinance, and water uses would be tailored to meet CALGreen Building Standards, which requires water conservation and requires new buildings to reduce water consumption by 20 percent. CMC Sections 16.58.100 through 16.58.140 set forth the standards for green building requirements by type of building. As shown on Table 101.10 in CMC Section

16.58.230, 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) (City’s preferred method), or Alternate Reference Standard pursuant to Section 101.10.2. 25 The proposed project will be conditioned
to meet one of these mandatory standards at the Building Permit phase. The LEED rating system encourages water use reduction. Specifically, in LEED v4.1 for Building Design and Construction (BD+C), Outdoor Water

24 City of Cupertino, June 2016, 2016 Bicycle Transportation Plan, https://www.cupertino.gov/files/assets/city/v/1/our- community/documents/cupertino-bicycle-transpor.pdf, accessed December 30, 2024. 25 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 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.

Use Reduction, Indoor Water Use Reduction and Building -level Water Metering are prerequisites for achieving Water Efficiency (WE) credits.

2.4.4.2 SANITARY SEWER SERVICE
The project site is located within the Cupertino Sanitary District (CSD) service area and wastewater would be treated at the San Jose/Santa Clara Water Pollution Control Plant (SJ/SCWPCD). Wastewater generated at the project site would be collected by the existing 8-inch sanitary sewer main on East Estates Drive.

2.4.4.3 STORMWATER MANAGEMENT
The proposed project would result in approximately 92,600 square feet of impervious surfaces coverage.

Compared to approximately 118,800 square feet of impervious surfaces coverage in existing conditions, this would be a decrease of approximately 26 ,200 square feet of impervious surfaces. Stormwater will be treated on site as required to meet municipal stormwater permit requirements. The proposed project includes 3,720 square feet of on -site bioretention areas that would hold and treat stormwater before it is discharged to an existing 15-inch public storm drain on East Estates Drive. The proposed 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 proposed project also must comply with CMC Chapter

9.18, Stormwater Pollution Prevention and Watershed Protection, which is intended to provide regulations and give legal effect to certain requirements of the National Pollutant Discharge Elimination System (NPDES) permit issued to the City.

2.4.4.4 SOLID WASTE SERVICES
Recology South Bay would provide curbside recycling, garbage, and compost and landscaping waste service to the project site.
26 Each garage will include designated space where waste and recycling bins must be stored. Residents will place their bins on their driveway for pickup. 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.

CITY OF CUPERTINO

2. Project Description

2.4.4.5 OTHER UTILITIES
Electric, cable, and telephone service is anticipated to connect to existing service lines along the north property line. A temporary overhead electric line would be installed to maintain power to the neighboring properties during construction. There are n o existing overhead lines along the project site frontage. New on-site utilities would be placed underground, with the exception of the temporary overhead electric line and four pad-mounted transformers. The existing overhead electric lines running along Richwood Drive will remain.

The proposed project would be all electric and Pacific Gas & Electric (PG&E) would supply electricity to the project site via existing infrastructure.27 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, 28 and PG&E. SVCE also offers a 100 percent renewable option that electricity customers can opt into. As previously stated in Section 2.4.4.1, Water Supply and Conservation, the proposed project would comply with the City’s adopted green building requirements, which includes the California Green Building Standards Code (Title 24) and is required to be Green Points Rated certified.

2.4.5 Demolition, Grading, and Construction
The proposed project demolition, grading, and construction is assumed to take place starting in summer 2026 and ending in 2028. The project applicant proposes to demolish the existing building on the project site.

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. Demolition and construction is not permitted on weekends or holidays for sites within 750 feet of other residential properties. 29 Demolition debris would be off-hauled for disposal in accordance with the City of Cupertino’s Recycling and Diversion of Construction and Demolition Waste Ordinance. 30 Preliminary grading plans show that there would be approximately 1,200 cubic yards of cut and 4,130 cubic yards of fill for a net 2,930 cubic yards of fill to be imported to the project site. Approximately 3,700 cubic yards of rock material would also be exported during the site preparation phase. Typical equipment to be used for demolition and site

preparation would include concrete/industrial saws, rubber tired dozers, tractors, loaders, backhoes, graders, and scrapers.

No pile driving, rock blasting, or crushing would occur during the construction phase. Typical equipment to be used during construction of the proposed project would include cranes, forklifts, generator sets, tractors, loaders, backhoes, welders, cement and mortar mixers, pavers, paving equipment, and rollers. In compliance with CMC Section 17.04.050(A)(3) which requires the use of Tier 4 or higher equipment, the project applicant has voluntarily committed to the use of Tier 4 Final equipment, which will also be a condition of approval.

During demolition and construction, vehicles, equipment, and materials would be staged and stored on a centrally located portion of the project site when practical. The construction staging would be reduced in size and equipment needs as the site is built out. The project applicant would be conditioned to restrict any long-term staging of equipment from being around the perimeter of the site 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 on - and off -site parking facilities for construction workers would be identified during demolition, grading, and construction.

2.4.6 Required Permits and Approvals
Following adoption of the CEQA Categorical Exemption, Streamlined Review, and the approval of the proposed project by the City Council, the following discretionary approvals from the City would be required for the proposed project:
 Tentative Map
 Architectural and Site Approval

residential development through the approval of a Conditional Use Permit . The proposed project would include the demolition of the existing commercial buildings and replacement with 55 residential townhome units and 10 ADUs . Therefore, implementation of the proposed project w ill not introduce a new incompatible land use to the project site. The proposed project is within the density allowed for the project site.31 Therefore, the proposed project is consistent with the General Plan land use designation for the project site. In addition, the proposed maximum building height of 45 feet is consistent with the 45-foot height limit allowed for the project site.

3.1.2 Zoning
As described in Section 2.3, Land Use and Zoning Designations, the project site’s zoning district at the time of project application is Planned Development with General Commercial with Multi -Family Residential (P(CG, R-4)), which allows for residential uses on the property. Therefore, the proposed project will not introduce a new incompatible use and will continue to be consistent with the zoning designation on the project site applicable at the time of project application.

3.2 CEQA GUIDELINES SECTION 15332(B): PROJECT LOCATION, SIZE,

AND CONTEXT
For the reasons stated here, the proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses and therefore meets the criteria of CEQA Guidelines Section 15332(b).

The proposed project is within city limits on an approximately 2.72-acre site. The project site is surrounded by urban uses and paved public streets, including commercial and residential uses, as shown on Figure 2-2, Aerial View of the Project Site and Surroundings. The project site is centrally located in the city and within a PDA and TPA. Accordingly, the proposed project meets the criteria of CEQA Guidelines Section 15332(b).

3. Exemption

The project site and surrounding area are developed with urban uses. Using data from the Classification and Assessment with Landsat of Visible Ecological Groupings (CALVEG)32 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 . The California Natural Diversity Database (CNDDB) has no record of special-status plant and animal species on the project site or urbanized areas within a one-mile area surrounding the project site.
33 There are no natural lands within a one-mile area of the project site. For these reasons, the project site has no value as habitat for endangered, rare, or threatened species.

While there is currently no landscaping on the project site, six existing off-site trees along Stevens Creek Boulevard will be removed as a part of the proposed project. Migratory birds, which are protected under the Migratory Bird Treaty Act, may use vegetation, including existing trees, on or near the project site for nesting. The project applicant will be required to comply with CMC Chapter 17.04, Standard Environmental Protection Requirements. Specifically, the project applicant will be required to comply with CMC Section

17.05.050(D)(1) listed here, which will minimize potential impacts to nesting birds during tree removal and construction:

CMC Section 17.04.050(D)(1) , Avoid Nesting Birds During Construction . For all projects that involve removal of a tree (either protected or unprotected) or other vegetation suitable for nesting birds, or construction or ground -disturbing activities defined in CMC Section 17.04.020, the project applicant shall comply with, and the construction contractor shall indicate the following on all construction plans, when required to ensure the following measures are performed to avoid inadvertent take of bird nests protected under the federal Migratory Bird Treaty Act and California Fish and Game Code when in active use:
a. Demolition, construction, ground -disturbing, and tree removal/pruning activities shall be scheduled to avoid the nesting season to the extent feasible. If feasible, construction, ground- disturbing, or tree removal/pruning activities shall be completed before the start of the nesting season to help preclude nesting. The nesting season for most birds and raptors in the San Francisco Bay area extends from February 1 through August 31. Preconstruction surveys (described below) are not required for construction, ground-disturbing, or tree removal/pruning activities outside the nesting period.
b. If demolition, construction, ground-disturbing, or tree removal/pruning activities occur during the nesting season (February 1 through August 31), preconstruction surveys shall be conducted as follows:

32 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. CALVEG maps use a hierarchical classification on the following categories: forest, woodland, chaparral, shrubs, and herbaceous. 33 California Natural Diversity Database, 2025, CNDDB Maps and Data, https://wildlife.ca.gov/Data/CNDDB/Maps-and-Data, accessed May 7, 2025.

i. No more than seven days prior to the start of demolition, construction, ground-disturbing, or tree removal/pruning activities to identify any active nests with eggs or young birds on the site and surrounding area within 100 feet of construction or tree removal activities. ii. Preconstruction surveys shall be repeated at 14-day intervals until demolition, construction, ground-disturbing, or tree removal/pruning activities have been initiated in the area, after which surveys can be stopped. As part of the preconstruction survey(s ), the surveyor shall inspect all trees and other possible nesting habitats in, and immediately adjacent to, the construction areas for active nests, while ensuring that they do not disturb the nests as follows:

1. For projects that require the demolition or construction of one single-family residence, ground--disturbing activities affecting areas of up to 500 square feet, or the removal of up to three trees, the property owner , or a tree removal contractor, if necessary, is permitted to conduct preconstruction surveys to identify if there are any active nests. If any active nests with eggs or young birds are identified, the project applicant shall retain a qualified ornithologist or biologist to identify protective measures.

2. For any other demolition, construction, and ground-disturbing activity or the removal of four or more trees, a qualified ornithologist or biologist shall be retained by the project applicant to conduct the preconstruction surveys.
c. If the preconstruction survey does not identify any active nests with eggs or young birds that would be affected by demolition, construction, ground-disturbing or tree removal/pruning activities, no further mitigating action is required. If an active nest containing eggs or young birds is found sufficiently close to work areas to be disturbed by these activities, their locations shall be documented, and the qualified ornithologist or biologist shall identify protective measures to be implemented under their direction until the nests no longer contain eggs or young birds. d. Protective measures may include, but are not limited to, 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 ornithologist or 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. The active nest within an exclusion zone shall be monitored on a weekly basis throughout the nesting season to identify signs of disturbance and confirm nesting status. The radius of an exclusion zone may be increased by the qualified ornithologist or biologist, if project activities are determined to be adversely affecting the nesting birds. Exclusion zones may be reduced by the qualified ornithologist or biologist only in consultation with California Department of Fish and Wildlife. The protection measures and buffers shall remain in effect until the young have left the nest and are foraging independently or the nest is no longer active.

3. Exemption

A final report on nesting birds and raptors, including survey methodology, survey date(s), map of identified active nests (if any), and protection measures (if required), shall be prepared by the qualified ornithologist or biologist and submitted to the Director of Community Development or his or her designee, through the appropriate permit review process (e.g., demolition, construction, tree removal, etc.), and be completed to the satisfaction of the Community Development Director prior to the start of demolition, construction, ground-disturbing, or tree removal/pruning activities.

In addition to protecting migratory birds, there are numerous bat species that are known to be in the Cupertino area, most of which are relatively common and are not considered special-status species. The CNDDB does not show any occurrences of special -status bats within the site vicinity or anywhere in Cupertino but does show records within several miles of Cupertino.34 The project applicant will be required to comply with CMC Chapter 17.04, Standard Environmental Protection Requirements. Specifically, the project applicant will be required to comply with CMC Section 17.05.050(D)(2) listed below, which will minimize potential impacts to roosting bats during tree removal and construction:

CMC Section 17.04.050(D)(2 ), Avoid Special -Status Roosting Bats During Construction Permit Requirements.
a. For all projects that involve demolition, renovation, or re- tenanting of an abandoned or vacant building or structure, where the property owner cannot show evidence to the satisfaction of the City of Cupertino Building Inspector that the building or struct ure was appropriately sealed at the time the building or structure was vacated to prevent bats from roosting, the project applicant shall retain a qualified biologist to conduct preconstruction surveys of the on-site buildings or structures prior to commencing any demolition, renovation, or re-tenanting activities. A building or structure is not appropriately sealed unless seal holes that are more than 0.5 inches in diameter or cracks that are 0.25 by 1.5 inches or larger are filled or closed with suitable material, such as caulking, putty, duct tape, self -expanding polyurethane foam, 0.25 -inch mesh hardware cloth, 0.5- inch or smaller welded wire mesh, installing tighter-fitting screen doors, or steel wool. b. The project applicant shall comply with, and the construction contractor shall include in the applicable construction documents, the following to ensure appropriate preconstruction surveys are performed and adequate avoidance provided for any special -status roosting bats, if encountered on the site. Preconstruction surveys shall:
i. Be conducted by a qualified biologist prior to tree removal or building demolition, renovation, or re-tenanting. Note that the preconstruction survey for roosting bats is required at any time of year since there is no defined bat roosting season as there is with nesting birds.

ii. Be conducted no more than 14 days prior to the start of tree removal or demolition, renovation, or re-tenanting.
iii. Be repeated at 14-day intervals until construction has been initiated, after which surveys can be stopped, unless construction activities are suspended for more than 7 consecutive days , at which point the surveys shall be reinitiated.
iv. If no special- status bats are found during the survey(s), then no additional measures are warranted.
c. Protective measures shall be included in the applicable construction documents and implemented prior to issuance of permits, if any special -status bat species are encountered or for any roosts detected within the existing structures, where individual bats could be inadvertently trapped and injured or killed during demolition unless passively evicted in advance of construction activities.

Protective measures shall include:
i. If no maternity roosts are detected, adult bats can be flushed out of the structure or tree cavity using a one-way eviction door placed over the exit location for a minimum 48 -hour period prior to the time tree removal or building demolition is to commence. ii. Confirmation by the qualified biologist that the one-way eviction door was effective, and that all bats have dispersed from the roost location, modifying any exclusion efforts to ensure individual bats have been successfully evicted in advance of initiating tree removal or building demolition.
iii. If a maternity roost is detected, and young are found roosting in a building identified for demolition, renovation, or re-tenanting, work shall be postponed until the young are flying free and are feeding on their own, as determined by the qualified biologist. iv. Once the qualified biologist has determined that any young bats can successfully function without the maternity roost, then the adults and young bats can be excluded from the structure to be demolished using the one-way eviction methods described above. v. Monitoring shall be provided by the qualified biologist as necessary to determine status of any roosting activity, success of any required bat exclusion, and status of any maternity roosting activity by bats, in the remote instance a maternity roost is encountered on the site.

Furthermore, the proposed applicant will be required to comply with CMC Chapter 19.102, Glass and Ligh
ting Standards, which establishes regulations to reduce bird mortality from windows, other specific glass features, and certain lighting elements that are known to increase the risk of bird collisions. No more than 10 percent of the surface area of the f açade will be untreated glass. The proposed project will avoid the funneling of flight paths along buildings or trees towards a building façade, avoid use of highly reflective glass or highly transparent glass, and not include skyways or walkways, balconies, freestanding walls, or building corners made of untreated glass or other transparent materials, or any other design elements that

are untreated and through which trees, landscape areas, water features , or the sky are visible from the exterior or from one side of the transparent element to the other. All outdoor lighting will be fully shielded fixtures, directed downward to meet the particular need and away from adjacent properties and rights-of- way to avoid light trespass.

Accordingly, the proposed project meets the criteria of CEQA Guidelines Section 15332(c).

3.4 CEQA GUIDELINES SECTION 15332(D): TRAFFIC, NOISE, AIR

QUALITY , OR WATER QUALITY
For the reasons stated here, the proposed project will not result in any significant effects related to traffic, noise, air quality, or water quality and therefore meets the criteria of CEQA Guidelines Section 15332(d).

3.4.1 Traffic
The analysis presented in this section is based in part on the Transportation Analysis for the Proposed Residential Development at 10065-10075 East Estates Drive in Cupertino, CA prepared for the proposed project and appended as Appendix B, Transportation Analysis, to this document.

The project site is in the eastern region of the city along Stevens Creek Boulevard. Regional access to the project site is provided by I -280 via North Wolfe Road to the north, and by Highway 85 via Stevens Creek Boulevard to the west. Vehicular access to and from the project site on Stevens Creek Boulevard will be provided through the access point on East Estates Drive.

The project site will continue to be accessible to pedestrians, bicyclists, and transit users. The site is served by the existing Enhanced Bike Lane on Stevens Creek Boulevard. Public transit to the project site is provided by local municipal bus lines 23, 25, 51, 55, and Rapid Transit 523 operated by the VTA with bus stops approximately 0.02 miles away on the north side of Stevens Creek Boulevard.

3.4.1.1 CONSISTENCY WITH CIRCULATION SYSTEM PROGRAMS AND PLANS Plan Bay Area 2050 is the Bay Area’s Regional Transportation Plan (RTP) and Sustainable Community Strategy (SCS) that identifies the sustainable vision for the Bay Area. An overarching goal of the regional plan is to concentrate development 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 VMT reductions. The proposed project is an infill development project within a Santa Clara VTA City

Cores, Corridors, and Station Areas PDA35 and within a TPA36 that will result in a change in land use from commercial to residential in a portion of the city that has access to existing infrastructure and services.

Therefore, the proposed project will not conflict with Plan Bay Area 2050.

Pedestrian, bicycle, and public transit access to and from the project site will not change from existing conditions. The proposed project will not increase the population at the project site such that it would result in a large number of vehicular trips (i.e., the existing commercial uses generate 350 net daily trips and the proposed project will generate approximately 100 net new daily trips to the project site) 37 and will not otherwise decrease the performance or safety of such pedestrian, bicycle, or public transit facilities or cause a substantial increase in transit demand that cannot be accommodated by existing or proposed transit capacity or alternative travel modes. Therefore, the proposed project will not result in changes to the City’s transportation and circulation system that could conflict with adopted policies, plans, or programs regarding transit, bicycle, or pedestrian facilities.

3.4.1.2 VEHICLE-MILES TRAVELED
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 land use development projects, transportation projects, and other projects pursuant to CEQA. 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.
 Land-use projects consisting of 100% affordable housing.

CEQA Guidelines Section 21155(b) defines a high-quality transit corridor means a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours. The closest bus stop to the project site is approximately 0.02 miles away on the north side of Stevens Creek Boulevard. The nearest transit stop is located 0.05 miles away, on the west side of Miller Avenue, which provides stops with a bus frequency service interval of 15 to 20 minutes during the peak weekday commute periods along VTA

As previously described in Section 3.4.1.1, Consistency with Circulation System Programs and Plans, the project site is within a TPA.38 Under the Plan Bay Area 2050 strategies, just under half of all Bay Area households would live within one-half mile of frequent transit by 2050, with this share increasing to over 70 percent for households with low incomes. Transportation and environmental strategies that support active and shared modes, combined with a transit-supportive land use pattern, are forecasted to lower the share of Bay Area residents that drive to work alone from over 50 percent in 2015 to 36 percent in 2050. Accordingly, development in a TPA demonstrates a cumulative decline of VMT in the city and region. Pursuant to the City’s Project Activity Map, the City is processing multiple applications for housing in the TPA.
39 Therefore, these projects, along with the proposed project, demonstrate a cumulative decline in VMT. As such, the proposed project meets the City’s VMT screening criteria of being within 0.25 miles of a major transit stop40 and declining cumulative VMT.

In addition, the City’s 2021 Transportation Study Guidelines provides detailed screening criteria to complete the screening process .41 T he 2021 Transportation Study Guidelines state that residential development projects located within a quarter-mile walkshed around an existing major transit corridor or a major transit stop (i.e. , along Stevens Creek Boulevard in Cupertino) may be screened out of further VMT analysis pursuant to the TPA screening criteria. However, TPA screening would not apply if the project meets any of the following criteria:
 The project has a Floor Area Ratio (FAR) of 0.75 or less;  The proposed parking exceeds the minimum required by the Zoning Code or applicable plan;  The Project is inconsistent with the City’s General Plan, applicable Specific Plan, or applicable Sustainable Communities Strategy (as determined by the lead agency, with input from ABAG and MTC);  The Project removes or reduces the number of existing on-site affordable residential units; or,  Significant levels of VMT generation are anticipated due to project -specific or location -specific information.

As described, the project site is within a quarter-mile walkshed around an existing major transit corridor due to its northern frontage located along Stevens Creek Boulevard. The proposed project would have a FAR greater than 0.75. The proposed project would replace commercial uses with 55 residential townhomes

and 10 ADUs and is consistent with the City’s General Plan. The City’s parking requirement for the proposed townhomes is 2.8 parking space per dwelling unit (CMC Table 19.124.040(A)) resulting in 154 spaces and the project parking includes 119 parking spaces. No affordable housing is being removed as a result of the proposed project, and as explained, development in a PDA and TPA is assumed to reduce cumulative VM T.

Accordingly, the proposed project qualifies for the TPA screening criteria, and no VMT-related impacts would occur .

3.4.1.3 DESIGN FEATURE OR INCOMPATIBLE USE HAZARDS
The proposed internal roadways will be constructed to be 24 to 39 feet wide and the proposed driveway along East Estates Drive to be approximately 26 feet wide, which is consistent with the CMC roadway standards. Since the increase of the number of vehicle trips resulting from the proposed project will be minor, the proposed driveway is expected to operate acceptably during both peak hours. The speed limit along East Estates Drive is 25 miles per hour (mph), for which the California Department of Transportation recommends a stopping sight distance of 200 feet. Some minor roadway curvature is present along East Estates Drive; however, a clear line of sight is available in both directions for at least 200 feet so that exiting vehicles can see along both directions of East Estates Drive. The proposed project will not include landscaping or signage along the project site frontage and entrances that will interfere with the corner triangles at the proposed driveways. The canopies of trees along East Estates Drive would be maintained so that they are at least 10 feet in height and do not impede the view of exiting drivers . While street parking is permitted along East Estates Drive, the red curb would be striped equal to one car length south of the proposed driveway and all the way to Stevens Creek Boulevard north of the proposed driveway. 42 Therefore,
no significant hazards in the area will occur during operation.

During the construction period, the proposed project will result in temporary changes to existing transportation conditions. Temporary traffic will be generated by construction employees and construction activities, including haul trucks. As discussed in Section 2.4.5, Demolition, Grading, and Construction, during demolition and construction, vehicle, equipment, and materials will be staged and stored on a portion of the project site. The construction site and staging areas will be clearly marked, and construction fencing will be installed to prevent disturbance and safety hazards. Therefore, no significant hazards in the area will occur during the construction phase.

3.4.1.4 EMERGENCY ACCESS
The proposed project will not alter the existing circulation pattern on Stevens Creek Boulevard. The proposed internal roadways will be constructed to 24 to 39 feet wide, consistent with the CMC and Cupertino Fire Department’s requirement s, and will provide emergency vehicles with sufficient space to access each of the residential units on -site. Therefore, the proposed project will not result in inadequate emergency access.

3.4.2 Noise
The analysis presented in this section is based in part on the Noise Technical Memorandum prepared for the proposed project and appended as Appendix C, Noise Analysis, to this document.

Pursuant to the CEQA Statute (Public Resources Code) Section 21085, for residential projects, the effects of noise generated by project occupants and their guests on human beings is not a significant effect on the environment. Accordingly, this section evaluates the noise from construction equipment, buildings, and vehicles.

The noise environment in the project vicinity is primarily characterized by vehicular traffic along Stevens Creek Boulevard to the north of the project site. Operations and activities from adjacent commercial, institutional, and residential uses also contribute to the existing noise environment in the project vicinity.

The closest existing noise-sensitive receptors to the project site are the adjacent single-family residences to the south of the project site along Richwood Drive.

3.4.2.1 AMBIENT NOISE LEVELS
Construction Impacts
According to CMC Section 10.48.053, Grading, Construction and Demolition, construction is allowed during “daytime hours” (7:00 a.m. to 8:00 p.m. Monday through Friday, and 9:00 a.m. to 6:00 p.m. on weekends) and exempt from the City’s daytime and nighttime maximum noise level limits, provided that such construction activities do not exceed 80 dBA at the nearest affected property or individual equipment items do not exceed 87 dBA at 25 feet. Only one of these two criteria must be met. In addition, constructi on is prohibited on holidays and within 750 feet of residential areas on weekends, holidays, and during the nighttime, unless a special exception has been granted, and during nighttime hours unless it meets the nighttime noise level standards. Even with these restrictions, project construction would temporarily increase ambient noise. However, noise levels would subside again after construction is completed.

Noise generated by on-site construction equipment is based on the type of equipment used, its location relative to sensitive receptors, and the timing and duration of noise- generating activities. Each stage of construction involves different kinds of equipment and has distinct noise characteristics. Noise levels from construction activities are typically dominated by the loudest pieces of equipment. The dominant noise source of construction equipment is typically the engine, although work -piece noise (such as dropping of materials) can also be noticeable.

The noise produced at each construction stage is determined by combining the contributions from each piece of equipment used at a given time, while accounting for the on -going time -variations of noise emissions (commonly referred to as the usage factor) to determine the L eq noise levels. Heavy equipment,
such as a bulldozer, can have maximum, short -duration noise levels of up to 85 dBA at 50 feet. However, overall noise emissions vary considerably, depending on what specific activity is being performed at a ny given moment. Noise attenuation due to distance, the number and type of equipment, and the load and power requirements to accomplish tasks at each construction phase would result in different noise levels from construction activities at a given receptor . Since noise from construction equipment is intermittent and diminishes at a rate of at least 6 dBA per doubling of distance (conservatively ignoring other attenuation effects from air absorption, ground effects, and/or shielding/scattering effects), the average noise levels at noise-sensitive receptors could vary considerably, because mobile construction equipment would move around the site with different loads and power requirements. Noise levels from project-related construction activities were calculated from the simultaneous use of all applicable construction equipment at spatially averaged distances (i.e., from the acoustical center of the general construction site or phase) to the property line of the nearest receptors. Although construction may occur across the entire phase area, the center of construction activities best represents the potential construction-related noise levels from multiple pieces of equipment at the various sensitive receptors. This is represented by the center of the entire construction site for activities such as paving, demolition, site preparation, and grading, which are expected to take place across the entire site. Other activities, such as building construction and architectural coating are expected to occur in a focused area of the construction site. Distances for these activities were measured from the nearest sensitive receptor to the nearest phase of potential focused construction activity. The expected construction equipment mix was estimated and categorized by construction activity and the three loudest equipment per activity phase using the Federal Highway Administration Roadway Construction Noise Model (RCNM). The associated, aggregate noise levels, grouped by construction activity, are summarized in Table 3-1, Project-Related Construction Noise, dBA L
eq Noise Leve ls. As shown in Table 3 -1, construction noise levels would not exceed 80 dBA L eq at nearby sensitive receptor locations, therefore complying with the City’s construction noise limit.

CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Sections 17.04.050(G)(1) and 17.04.050(G)(2) listed here, which will minimize impacts related to construction noise:

CMC Section 17.04.050(G)(1), Notice and Signage. At least 10 days prior to the start of any demolition, ground disturbing, or construction activities, because the project site is between 0.25 to 0.5 acres, the project applicant shall send notices shall be sent to off-site businesses and residents within 250 feet of the project site. The notification shall include a brief description of the project, the activities that would occur, the hours when activity would occur, and the construction period’s overall duration. The notification should include the telephone numbers of the contractor’s authorized representatives that are assigned to respond in the event of a noise or vibration complaint. The project applicant shall provide the City with evidence of mailing of the notice, upon request. Additionally, the at least 10 days prior to the start of construction activities, a sign shall be posted at the entrance(s) to the job site, clearly visible to the public, which includes permitted construction days and hours, a s 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 shall investigate, take appropriate corrective action, and report the action to the City within three business days of receiving the complaint.

CMC Section 17.04.050(G)(2), Manage Noise During Construction. a. The project applicant and contractors shall prepare and submit a Construction Noise Control Plan to the City’s Planning Department for review and approval prior to issuance of the first permit. The

Construction Noise Plan shall demonstrate compliance with daytime and nighttime decibel limits pursuant to Chapter 10.48 (Community Noise Control) of Cupertino Municipal Code. The details of the Construction Noise Control Plan shall be included in the applicable construction documents and implemented by the on -site Construction Manager . Noise reduction measures selected and implemented shall be based on the type of construction equipment used on the site, distance of construction activities from sensitive receptor(s), site terrain, and other features on and surrounding the site (e.g., trees, built environment) and may include, but not be limited to, temporary construction noise attenuation walls, high quality mufflers. During the entire active construction period, the Construction Noise Control Plan shall demonstrate that compliance with the specified noise control requirements for construction equipment and tools will reduce construction noise in compliance with the City’s daytime and nighttime decibel limits. b. 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. c. 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. d. 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, whic h 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 law.

Pursuant to CMC Section 17.04.050(G)(2), the proposed project would be required to prepare and implement a noise control plan to ensure compliance with daytime and nighttime decibel limits in the CMC.

Therefore, the proposed project will not increase ambient noise levels in the vicinity of the project in excess of standards established in the CMC during the construction phase.

Operational Impact
Stationary-Source Noise
Noise from sources such as people talking and using outdoor common areas or property maintenance may contribute to the total noise environment within the direct vicinity of the proposed project site. However, these types of noise are commonly associated with uses that already exist on the project site and surrounding uses. CMC Section 10.48.040, Daytime and Nighttime Maximum Noise Levels, sets the maximum noise level at the site of a receiving residential property to be 60 dBA during the daytime and 50 dBA during the nighttime and 65 dBA during the daytime and 55 dBA during the nighttime at the site of a receiving nonresidential property. Noise associated with landscape maintenance activities is exempt from

the provisions of the CMC, provided said activities take place between the hours of 7:00 a.m. to 8:00 p.m. on weekdays, and 9:00 a.m. to 6:00 p.m. on weekends and holidays.

The project’s common space area is in the center of the proposed project, approximately 170 feet north of the nearest residence on Richwood Drive. A typical conversation between two people 3 feet apart is 60 dBA.
43 At a distance of 170 feet, noise levels would attenuate to approximately 25 dBA. Therefore, noise from typical use of the open space area would result in noise levels less than the CMC Section 10.48.040 nighttime 50 dBA limit for residential uses.

The proposed townhomes are anticipated to have mechanical heating, ventilation, and air conditioning (HVAC) equipment on the ground next to units or on the on the rooftop. The exterior mechanical and HVAC equipment associated with the proposed townhomes are expected to be similar to the existing commercial uses on the site or quieter . Because mechanical specifications for these proposed units are not yet available, it is conservatively assumed that noise from these units would be up to 72 dBA L eq at a distance of 3 feet
and that they could be located within approximately 45 feet from the nearest residential property lines to the west. At this distance, the sound pressure level associated with a common HVAC unit would be approximately 48 dBA at the nearest noise sensitive receptor . Therefore, the noise level associated with HVAC in the backyards of the future residential units would not exceed the CMC Section 10.48.040 standards, which limit nighttime noise to 50 dBA at nearby residential uses.

Traffic Noise
The proposed project would generate an increase of 100 net new trips per day with 15 new AM peak hour trips compared to existing daily trips attributed to the existing shopping center at the project site. A project will normally have a significant effect on the environment related to traffic noise if it substantially increases the ambient noise levels for adjoining areas. Most people can detect changes in sound levels of approximately 3 dBA under normal, quiet conditions, and changes of 1 to 3 dBA under qui et, controlled conditions. Changes of less than 1 dBA are usually indiscernible. A change of 5 dBA is readily discernible to most people in an outdoor environment. Noise levels above 65 dBA CNEL are normally unacceptable at sensitive receptor locations such as residences, schools, and noise environments in these areas would be considered degraded. Based on this, a significant impact would occur if traffic noise increases by 3 dBA.

Traffic noise increases were calculated using a version of the F ederal Highway Administration RD-77-108 Traffic Noise Prediction Model. The traffic noise prediction model takes into account the following inputs:
average daily traffic volumes; vehicle mix; speeds; number of lanes; and day, evening, and night traffic splits.

Existing traffic noise estimates are based on the City of Cupertino’s baseline roadway volumes modeled for

3.4.2.2 GROUNDBORNE VIBRATION
Potential vibration impacts associated with construction projects are usually related to the use of heavy construction equipment during the demolition phase of construction. Construction can generate varying degrees of ground vibration depending on the con struction procedures and equipment. Construction equipment generates vibration that spreads through the ground and diminishes with distance from the source. The effect on buildings in the vicinity of the construction site varies depending on soil type, ground strata, and receptor-building construction. The effects from vibration can range from no perceptible effects at the lowest vibration levels, to low rumbling sounds and perceptible vibrations at moderate levels, to slight structural damage at the highest levels. Vibration from construction activities rarely reaches the levels that can damage structures. Table 3 -3, Vibration Levels at Nearby Structures, summarizes vibration levels for typical construction equipment at the nearest structures to the project site. As noted in Table 3-3 , the vibratory roller, which would be used during paving activities on project streets, would produce the highest levels of vibration. Therefore, the distances shown in Table 3-3 reflect the distance from the nearest off-site buildings to the nearest paved street area shown on the proposed site plan.

The nearest structure to the site’s construction activities, the residential/daycare building to the southwest, is approximately 80 feet from the nearest proposed project construction activities. At this distance, construction vibration would attenuate to 0.037 inches per second peak particle velocity (in/sec PPV) or less. Vibration levels at the other nearby residence 130 feet south of the project site and the commercial uses to the west would also attenuate to 0.018 in/sec PPV or less. Therefore, proposed construction activities would not exceed the City’s vibration standard of 0.2 in/sec PPV or 0.12 in/sec PPV (for historic structures) at nearby off-site structures.

CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Section 17.04.050(G)(3), which will minimize impacts related to construction vibration:

CMC Section 17.04.050(G)(3) , Manage Vibrations During Construction. In the event pile driving is required, the project applicant shall:
a. Notify all vibration-sensitive receptors within 300 feet of the project site of the schedule 10 days prior to its commencement and include the contact information for the person responsible for responding to complaints on site.
b. The project applicant shall retain a qualified acoustical consultant or structural engineer, to prepare and implement a Construction Vibration Monitoring Plan, which is subject to third -party peer review under the direction of the City at the applicant’s c ost, for areas within 100 feet for pile driving, 25 feet for vibratory roller, or 15 feet for other heavy equipment (e.g., bulldozer); and for historical structures: within 135 feet for pile driving, 40 feet for vibratory roller, or 20 feet for other

heavy equipment. The plan shall include surveying the condition of existing structures; and determining the number, type, and location of vibration sensors and establish a vibration velocity limit (as determined based on a detailed review of the proposed b uilding), method (including locations and instrumentation) for monitoring vibrations during construction, location of notices displaying the contact information for on-site coordination and complaints on site, and method for alerting responsible persons who have the authority to halt construction should limits be exceeded or damaged observed.
c. Submit final monitoring reports to the City upon completion of vibration related construction activities.
d. Conduct a post-survey on any structure where either monitoring has indicated high vibration levels or complaints that damage has occurred are received.
e. The project applicant shall be responsible for appropriate repairs as determined by the qualified acoustical consultant or structural engineer where damage has occurred as a result of construction activities.

Should the proposed project require the use of the construction equipment listed in CMC Section

17.04.050(G)(3)(b) within the specified distances to receptors, it will be required to prepare a Construction and Vibration Monitoring Plan by a qualified acoustical consultant to ensure that no damage due to vibration from construction equipment would occur. Therefore, the proposed project will not result in an increase in excessive ground-borne vibration.

3.4.2.3 AIRPORT NOISE
Because the project site is not within two miles of a private or public use airport, which is the standard for assessing noise impacts under CEQA, the proposed project will not result in the exposure of people residing or working in the project area to excessive noise levels associated with the proximity of an airport.

3.4.3 Air Quality
The analysis presented in this section is based in part on the Air Quality Technical Memorandum and Health Risk Assessment prepared for the proposed project and appended as Appendix D, Air Quality Analysis, to this document.

The analysis of the proposed project’s air quality impacts follows the guidance and methodologies recommended in the Bay Area Air District (Air District)46 2022 CEQA Air Quality Guidelines. CEQA allows the significance criteria established by the applicable air quality management or air pollution control district to be used to assess impacts of a project on air quality. The guidelines provide recommended procedures for

evaluating potential air impacts during the environmental review process, consistent with CEQA requirements, and include recommended thresholds of significance, mitigation measures, and background air quality information.

Attainment Status of the Air Basin
The proposed project is in the San Francisco Bay Area Air Basin (Air Basin) under the jurisdiction of the Air District, which regulates air quality in the San Francisco Bay Area. Within the Air Basin, ambient air quality standards for ozone, carbon monoxide (CO), nitrogen dioxide (NO 2), sulfur dioxide (SO2), particulate matter
(PM10, PM2.5), and lead (Pb) have been set by both the State of California and the federal government. The State has also set standards for sulfate and visibility. The Air Basin is un der State nonattainment status for ozone and particulate matter (both PM10 and PM2.5) standards. The Air Basin is classified as nonattainment for the federal ozone 8-hour standard and nonattainment for the federal 24-hour standard for PM2.5.47 Air Quality Plans
The Air District is directly responsible for reducing emissions from area, stationary, and mobile sources in the Air Basin to achieve national and California Ambient Air Quality Standards (AAQS). The Air District’s 2017 Clean Air Plan is a regional and multiagency effort to reduce air pollution in the Air Basin . 48 A consistency
determination with the air quality management plan plays an important role in local agency project review by linking local planning and individual projects to the 2017 Clean Air Plan. It fulfills the CEQA goal of informing decision makers of the environmental efforts of the project under consideration early enough to ensure that air quality concerns are fully addressed. It also provides the local agency with ongoing information as to whether they are contributing to the clean air goals in the 2017 Clean Air Plan.

Regional Significance Thresholds
As described previously, the Air Basin is currently designated a nonattainment area for California and National O
3, California and National PM 2.5, and California PM 10 air quality standards. 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 Air Basin), a project is cumulatively significant when project-related emissions exceed the Air District’s emissions thresholds.

PlaceWorks Page 40
The Air District has identified thresholds of significance for criteria pollutant emissions and criteria air pollutant precursors, including reactive organic gas (ROG), NO X, PM 10, and PM 2.5. 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.

CO Hotspots
Congested intersections have the potential to create elevated concentrations of CO, referred to as CO hotspots. The significance criteria for CO hotspots are based on the California AAQS for CO, which are 9.0 ppm (8-hour average) and 20.0 ppm (1-hour average). With the turnover of older vehicles, introduction of cleaner fuels, and implementation of control technology, the SFBAAB is in attainment of the California and national AAQS, and CO concentrations in the SFBAAB have steadily declined. Because CO concentrations have improved, the Air District does not require a CO hotspot analysis if the following criteria are met:
 The project is consistent with an applicable congestion management program established by the County Congestion Management Agency for designated roads or highways, the regional transportation plan, and local congestion management agency plans.
 The project would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour .
 The project traffic would not increase traffic volumes at affected intersection to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, bridge underpass, natural or urban street canyon, below-grade roadway).

Health Risk
The Air District’s significance thresholds for local community risk and hazard impacts apply to both the siting of a new source and to the siting of a new receptor . Local community risk and hazard impacts are associated with TACs and PM

2.5 because emissions of these pollutants can have significant health impacts at the local level. The proposed project would generate TACs and PM2.5 during construction activities that could elevate concentrations of air pollutants at the nearby receptors. The thresholds for construction-related local community risk and hazard impacts are the same as for project operations. The Air District has adopted screening tables for air toxics evaluation during construction. Construction -related TAC and PM2.5 impacts are addressed on a case -by-case basis, taking into consideration the specific construction -related characteristics of each project and proximity to off-site and on-site receptors, as applicable.

Project-level emissions of TACs or PM 2.5 from individual sources that exceed any of the thresholds listed below are considered a potentially significant community health risk in the absence of a qualified community risk reduction plan:

 An excess (i.e., increased) cancer risk level of more than 10 in one million  Noncancer (i.e., chronic or acute) hazard index greater than 1.0  An incremental increase of greater than 0.3 micrograms per cubic meter (µg/m3) annual average PM2.5 Cumulative sources represent the combined total risk values of each of the individual sources within the 1,000-foot evaluation zone. A project would have a cumulatively considerable impact if the aggregate total of all past, present, and foreseeable future sources within a 1,000-foot radius from the fence line of a source or location of a receptor, plus the contribution from the project, exceeds any of the following in the absence of a qualified community risk reduction plan:
 An excess cancer risk level of more than 100 in one million (from all sources)  Chronic noncancer hazard index (from all local sources) greater than 10.0  0.8 µg/m3 annual average PM2.5 (from all local sources)

3.4.3.2 CONSISTENCY WITH APPLICABLE AIR QUALITY PLANS
The regional emissions inventory for the Air Basin is compiled by the Air District. Regional population, housing, and employment projections developed by the Association of Bay Area Governments (ABAG) are based, in part, on cities’ general plan land use designations. These projections form the foundation for the emissions inventory of the 2017 Clean Air Plan. These demographic trends are incorporated into Plan Bay Area 2050, compiled by ABAG and the Metropolitan Transportation Commission (MTC) to determine priority transportation projects and vehicle miles traveled in the Bay Area. The 2017 Clean Air Plan strategy is based on projections from local general plans. Projects that are consistent with the local general plan are considered consistent with the air quality -related regional plan. Large projects that exceed regional employment, population, and housing planning projections have the potential to be inconsistent with the regional inventory compiled as part of the 2017 Clean Air Plan.

The proposed residential uses would be consistent with the Commercial/Residential land use designation of the General Plan. Additionally, under CEQA Guidelines Section 15206, 49 the proposed project is not
considered a regionally significant project that would affect regional vehicle miles traveled and warrant intergovernmental review by ABAG and MTC. Additionally, the proposed project would serve the existing community and not induce substantial unplanned population growth. Lastly, as shown in Table 3-5 , the proposed project would not generate operational emissions that would exceed the Air District’s emissions thresholds. These thresholds are established to identify projects that have the potential to generate a substantial amount of criteria air pollutants. Because the proposed project would not exceed these thresholds, the proposed project would not be considered by the Air District to be a substantial emitter of

49 Pursuant to CEQA Guidelines Section 15206(b)(2)(A), a proposed residential development of more than 500 dwelling units would be considered a project of statewide, regional, or areawide significance.

criteria air pollutants. Therefore, the proposed project would not conflict with or obstruct implementation of the 2017 Clean Air Plan.

3.4.3.3 CUMULATIVELY CONSIDERABLE NET INCREASE CRITERIA POLLUTANT 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 course fugitive dust (PM 10) and fine fugitive dust
(PM2.5) from demolition and soil- disturbing activities, such as grading and excavation. Air pollutant emissions from construction activities on -site will vary daily as construction activity levels change.

Construction activities associated with the proposed project will result in emissions of ROG, NOX, PM10, and PM2.5.

CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Sections 17.04.050(A)(1), 17.04.050(A)(3), and 17.04.050(A)(4) as listed here, which will minimize impacts from construction:

CMC Section 17.04.050(A)(1), Control Fugitive Dust During Construction. Projects shall implement the Bay Area Air Quality Management District Basic Control Measures included in the latest version of BAAQMD’s CEQA Air Quality Guidelines, as subsequently revised, supplemented, or replaced, to control fugitive dust (i.e., particu late matter, PM

2.5 and PM10) during demolition, ground-disturbing activities, and/or construction. The project applicant shall include these measures in the applicable construction documents, prior to issuance of the first permit.

CMC Section 17.04.050(A)(3), Control Construction Exhaust. Projects that disturb more than one -acre and are more than two months in duration, shall implement the following measures and the project applicant shall include them in the applicable construction document, prior to issuance of the first permit:
a. Utilize off-road diesel- powered construction equipment that is rated by the U.S. Environmental Protection Agency (EPA) as Tier 4 or higher for equipment more than 25 horsepower . Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Tier 4 interim emissions standard for a similarly sized engine, as defined by the California Air Resources Board’s (CARB) regulations. Applicable construction documents shall clearly show the selected emission reduction strategy for construction equipment over 25 horsepower .

b. Ensure that the construction contractor shall maintain a list of all operating equipment in use on the project site for verification by the City. The construction equipment list shall state the makes, models, and number of construction equipment on-site.
c. Ensure that all equipment shall be properly serviced and maintained in accordance with the manufacturer’s recommendations.

CMC Section 17.04.050(A)( 4), Control Volatile Organic Compound Emissions from Pain t. Project shall use low VOC-paint (i.e., 50 grams per [g/l] or less) for interior and exterior wall architectural coatings.

The project applicant shall include the use of low-VOC paint in the applicable construction documents prior to issuance of the first permit.

In reference to CMC Section 17.04.050(A)(1), the Air District considers all impacts related to fugitive dust emissions from construction to be less than significant with implementation of the Air District’s best management practices. The current best management practices that are required to be implemented by the project applicant are listed herein:
 All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day.
 All haul trucks transporting soil, sand, or other loose material off-site shall be covered.  All visible mud or dirt tracked-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.  All vehicle speeds on unpaved roads shall be limited to 15 miles per hour .  All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.  Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used.  Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations). Clear signage shall be provided for construction workers at all access points.
 All construction equipment shall be maintained and properly tuned in accordance with the manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation.
 A publicly visible sign shall be posted with the telephone number and person to contact at the City of Cupertino regarding dust complaints. This person shall respond and take corrective action within 48 hours. The phone number shall also be visible to ensure compliance with applicable regulations.

Construction is anticipated to occur from Summer 2026 to 2028. For the purposes of this analysis, a 21- month construction schedule was utilized, with construction starting in August 2026 and lasting until May 2028. Based on information provided by the appl icant, construction activities are expected to occur 11 hours a day Monday through Friday and 9 hours a day on Saturdays.

Construction emissions were estimated using CalEEMod version 2022.1. Table 3-4, Construction Criteria Air Pollutant Emissions, shows the average daily construction emissions of ROG, NOX, PM10 exhaust, and PM2.5 exhaust during construction of the proposed project. As indicated in Table 3-4, average project construction emissions will not exceed the Air District’s significance thresholds. Therefore, the proposed project will not result in a cumulatively considerable net increase of criteria air pollutants during the construction phase.

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). Types of land uses that typically generate substantial quantities of criteria air pollutants and toxic air contaminants include industrial (stationary sources), manufacturing, and warehousing (truck idling) land uses. These types of major air pollutant emissions sources are not included as part of the proposed project.

As described in Section 2.4.4, Utilities and Public Service Providers , the proposed project will be designed as 100 percent electric, which will also be a condition of approval, and will not include stationary sources that emit toxic air contaminants or generate a significant amount of heavy -duty truck trips (a source of diesel particulate matter).

Carbon Monoxide Hotspots
Areas of vehicle congestion have the potential to create pockets of CO, called hotspots. These pockets have the potential to exceed the State’s 1-hour standard of 20 parts per million (ppm) or the 8-hour standard of 9 ppm.

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 —to generate a significant CO impact. The proposed project will result in 100 net new daily vehicle trips (15 AM peak hour trips). 50 Thus, the proposed project will 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. 51 The proposed project will not
have the potential to substantially increase CO hotspots at intersections in the project vicinity. Therefore, the proposed project will not increase CO concentration at intersections.

3.4.3.4 SENSITIVE RECEPTORS
Project impacts related to increased health risk can occur by generating emissions of TACs and air pollutants.

Construction activity under the proposed project will generate dust and equipment exhaust that can affect nearby sensitive receptors. The proposed project will include a stationary source of air pollutants and TACs in the form of an emergency generator and will also generate some traffic consisting of mostly light -duty gasoline-powered vehicles, which will produce TAC and air pollutant emissions.

The closest existing sensitive receptors to the project site are at the adjacent single- family residences and daycare to the south and southwest, respectively. The nearest school receptor is a private academy (Fusion Academy Cupertino) located in the shopping mall adjacent to the project site, approximately 450 feet to the west.

Health risk impacts were addressed by predicting increased cancer risk, the increase in annual PM

2.5 concentrations, and by computing the Hazard Index for noncancer health risks. The project’s maximally exposed receptor (MER) is identified as the sensitive receptor that is most impacted by the project’s construction and operation. The cancer risk MER is at the residence/daycare southwest of the project site and the annual PM2.5 MER is at the shopping center approximately 80 feet west of the project site.

Table 3-6, Construction Risk Summary , summarizes the maximum cancer risks, PM 2.5 concentrations, and health Hazard Index for construction-related activities. As shown in Table 3-6, for non-carcinogenic effects, the chronic hazard index identified for each toxicological endpoint equaled less than one for each identified receptor, which is within acceptable limits. Cancer risk for the worker, daycare, and K-12 student receptors were each calculated to be less than 1 in one million, which would not exceed the 10 in one million significance threshold. However, with the use of Tier 4 Interim equipment, cancer risk for the residential MER from project -related construction emissions was calculated to be approximately 18 in one million, which would exceed the 10 in one million significance threshold. Similarly, with the use of Tier 4 Interim equipment, the annual average PM

2.5 concentration at the worker MER would reach 0.303 µg/m 3, which would exceed the Air District’s significance threshold of 0.3 µg/m3. However, as discussed in Section 2.4.5, Demolition, Grading, and Construction, in compliance with CMC Section 17.04.050(A)(3), the project applicant has voluntarily committed to the use of Tier 4 Final equipment , which will also be a condition of approval. With the use of Tier 4 Final equipment, cancer risk for the residential MER from project -related construction emissions would be 6.45 in one million, under the Air District’s significance threshold. Similarly, the annual average PM 2.5 concentration at the worker MER would reach 0.27 µg/m 3, which is also under the Air District’s significance threshold.

1. While risks were calculated for each type of student receptor separately (including preschool, elementary school, middle s chool, and high school), these results report the highest risk among all student receptor types, the middle school student receptors at Fusion Academy Cupertino.

In addition to a project -level health risk assessment , the Air District recommends assessing the potential cumulative impacts from sources of TACs within 1,000 feet of a project. The existing TACs that the Air District recommends a cumulative analysis include permitted stationary sources, marine sources, roadway sources, rail sources, and highway sources. Risks from permitted stationary sources within 1,000 feet of the project site can be identified using the Air District’s Stationary Source Screening Map. 52 The residential MER was
utilized in the cumulative community risk assessment as it represents the greatest impact to nearby receptors during project construction. No marine or rail risks are shown in the cumulative health risk assessment as no marine or rail activities occur within 1,000 feet of the project site.

Table 3-7, Cumulative Community Risk Summary, summarizes the existing TAC source risks at the residential MER from mitigated project construction emissions in combination with existing TAC sources within 1,000 feet of the project site. As shown therein, the proposed project’s construction emissions with Tier 4 Final equipment combined with existing TAC emissions within 1,000 feet do not exceed the Air District’s cumulative community health risk significance thresholds at the residential MER location.

3.4.3.5 ODORS
Construction activities could also generate odors from construction equipment, such as diesel exhaust, and VOCs from architectural coatings and paving activities. However, these odors will be temporary and limited to the construction period. By the time such emissions reach any sensitive receptor sites, they would be diluted well below any level of air quality concern.

The type of facilities that are typically 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. 53 The proposed project consists of residential development, which is not considered a type of land use typically associated in generating objectionable odors that would affect a substantial number of people. Therefore, the proposed project will not create objectionable odors affecting a substantial number of people.

3.4.3.6 GREENHOUSE GAS EMISSIONS
A project does not generate enough greenhouse gas (GHG) emissions on its own to influence global climate change; therefore, this section measures the proposed project contribution to the cumulative environmental impact associated with GHG emissions. Development of the proposed project will contribute to climate change through direct and indirect GHG emissions from the construction activities needed to implement the proposed project, which will generate a short-term increase in GHG emissions.

Construction Impacts
The Air District does not have thresholds of significance for construction-related GHG emissions, which are one-time, short-term emissions and therefore will not significantly contribute to the long-term cumulative GHG emissions impacts of the proposed project. Implementation of the Air District’s basic construction best management practices required pursuant to CMC Section 17.04.050(A)(1) will reduce GHG emissions by reducing the amount of construction vehicle idling and by requiring the use of properly maintained equipment. Therefore, project construction impacts associated with GHG emissions will be reduced to the extent feasible, as required by the Air District.

Operational Impacts
The proposed project will generate a net increase of 209 daily weekday trips compared to existing on -site land uses. Because transportation emissions will generate the majority of GHG emissions associated with the proposed project, this net increase in daily trips will not substantially increase GHG emissions in the city.

Additionally, the new buildings will be more energy efficient than the existing structures and will be built to achieve the latest Title 24 Building and Energy-Efficiency Standards.

The Air District has the following thresholds for land use projects in analyzing GHG emissions impacts; projects must include conditions listed under either Criterion A or B:

A. Projects must include, at a minimum, the follow project design elements:

1. Buildings
a. The project will not include natural gas appliances or natural gas plumbing (in both residential and nonresidential development).
b. The project will not result in any wasteful, inefficient, or unnecessary energy usage as determined by the analysis required under CEQA Section 21100(b)(3) and Section 15126.2(b) of the State CEQA Guidelines.

2. Transportation
a. Achieve a reduction in project -generated vehicle miles traveled (VMT) below the regional average consistent with the current version of the California Climate Change Scoping Plan (currently 15 percent) or meet a locally adopted Senate Bill 743 VMT target, reflecting the

PlaceWorks Page 50
recommendations provided in the Governor’s Office of Land Use and Climate Innovation 's Technical Advisory on Evaluating Transportation Impacts in CEQA:
i. Residential projects: 15 percent below the existing VMT per capita ii. Office projects: 15 percent below the existing VMT per employee iii. Retail projects: no net increase in existing VMT
b. Achieve compliance with off -street electric vehicle requirements in the most recently adopted version of CALGreen Tier 2.

B. Projects must be consistent with a local GHG reduction strategy that meets the criteria under State CEQA Guidelines Section 15183.5(b).

As described herein, the proposed project will meet the conditions listed under Criterion B, for being consistent with a locally adopted GHG reduction strategy. In addition, it will not include natural gas appliances or plumbing, or result in any wasteful, inefficient, or unnecessary energy usage, as previously explained. Other applicable plans adopted for the purpose of reducing GHG emissions include the California Air Resources Board’s (CARB) Climate Change Scoping Plan (Scoping Plan) and Plan Bay Area 2050. A consistency analysis with these plans is also presented herein.

Cupertino Climate Action Plan
The Cupertino Climate Action Plan 2.0 (CAP 2.0) is a strategic planning document that identifies sources of GHG emissions in 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, land use, water, solid waste, and green infrastructure sectors.

A specific project proposal is considered consistent with the Cupertino CAP 2.0 if it does not conflict with the required GHG reduction measures contained in the adopted CAP . Project consistency with the adopted GHG reduction measures is shown in Table 3-8, Cupertino Climate Action Plan Consistency Matrix.

Consistent. The City is the responsible party for this measure. As described in Chapter 2, Project Description , while the proposed project does not propose any new bicycle lanes or routes, the site is accessible from the existing Enhanced Bike Lane on Stevens Creek Boulevard. As such, the proposed project will not conflict with the City’s 2016 Bicycle Transportation Plan. Pedestrians will also have access to the site via the existing sidewalks that will connect to the pedestrian network surrounding the proj ect site. Therefore, the proposed project will promote and will not obstruct these alternative modes of transportation.

The proposed project will include 3,720 square feet of on-site bioretention facilities that will hold and treat stormwater before dispersal to the City’s off -site storm drain infrastructure. Furthermore, the project will compl y with the Santa Clara Valley Urban Runoff Pollution Prevention Program C.3 and CMC Chapter 9.18, Stormwater Pollution Prevention and Watershed Protection
, to ensure ongoing
compliance with the City’s municipal stormwater and urban runoff requirements. The proposed project will not conflict with implementation of this measure.

Notes: Measures BE-2 and BE-3 apply to existing development and are not applicable. Measure TR-4 is a city measure to re-focus transportation infrastructure in the city that is not applicable on a project-level. Measure CS-2 is for open space projects that can sequester carbon dioxide (CO2), and therefore, is not directly applicable to the project.

Furthermore, CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Section 17.04.050(C), which will minimize stormwater runoff:

CMC Section 17.04.050(C), Reduce Greenhouse Gas Emissions (GHG) and Energy Use . The project applicant shall complete the City of Cupertino Climate Action Plan – Development Project Consistency Checklist, for review and approval by the City Environment and Sustainability Department prior to issuance of the first permit, to demonstrate how the project is consistent with the Cupertino Climate Action Plan, as subsequently revised, supplemented, or replaced, in order to reduce greenhouse gas emissions and conserve energy.

Therefore, the proposed project will be consistent with Cupertino CAP 2.0.

CARB’s Scoping Plan
CARB’s Scoping Plan outlines the State’s strategies to reduce GHG emissions in accordance with the targets established under SB 32, Assembly Bill (AB) 32, and Executive Order (EO) B -55-18. The Scoping Plan is applicable to State agencies and is not directly applicable to cities/counties and individual projects.

Nonetheless, 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. CARB recently released the 2022 Scoping Plan to address measures to achieve the State’s carbon neutrality goals under EO B-55-18.

Statewide strategies to reduce GHG emissions in the 2017 Climate Change Scoping Plan include implementing SB 350, which expands the Renewable Portfolio Standards to 50 percent by 2030 and doubles energy-efficiency savings; expanding the Low Carbon Fuel Sta ndards (LCFS) to 18 percent by 2030; implementing the Mobile Source Strategy to deploy zero- electric vehicle buses and trucks; implementing the Sustainable Freight Action Plan; implementing the Short -Lived Climate Pollutant Reduction Strategy, which reduces methane and hydrofluorocarbons to 40 percent below 2013 levels by 2030, and black carbon emissions to 50 percent below 2013 levels by 2030; continuing to implement SB 375; creating a post-2020 Cap-and-Trade Program; and developing an Integrated Natural a nd Working Lands Action Plan to secure California’s land base as a net carbon sink.

Statewide strategies to reduce GHG emissions include the low carbon fuel standards, California Appliance Energy Efficiency regulations, California Renewable Energy Portfolio standard, changes in the CAFE standards, and other early-action measures as necessary to ensure the State is on target to achieve the GHG emissions-reduction goals of SB 32, AB 32, and EO B -55-18. In addition, new buildings are required to comply with the current Building Energy -Efficiency Standards and CALGreen. The Cupertino CAP 2.0 i s consistent with the statewide GHG reduction strategy and therefore complying with the CAP 2.0 will ensure the proposed project complies with the CARB Scoping Plan. The project’s GHG emissions will be reduced

from compliance with statewide measures that have been adopted since SB 32, AB 32, and EO B-55-18 were adopted.

Plan Bay Area
Plan Bay Area 2050 is the Bay Area’s RTP/SCS that identifies a sustainable vision for the Bay Area. To achieve the MTC/ABAG’s sustainable vision for the Bay Area, the Plan Bay Area 2050 land use concept plan for the region concentrates the majority of new population and employment growth in the region in PDAs. An overarching goal of the regional plan is to concentrate development 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, VMT, and associated GHG emissions reductions. The project site is in a Santa Clara VTA City Cores, Corridors, and Station Areas PDA and the proposed project is an infill development project that will 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. Therefore, the proposed project will be consistent with Plan Bay Area 2050.

3.4.4 Water Quality

3.4.4.1 WATER QUALITY STANDARDS
The City, as a participant in the Santa Clara Valley Urban Runoff Pollution Prevention Program, which is regulated by the NPDES Program, is committed to reducing pollutants entering waterways. Below is a discussion of the proposed project’s compliance with water quality standards.

Construction Impacts
Because the proposed project is greater than one acre, it will be required to comply with the General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activity (Construction General Permit). The proposed project will also be required to comply with the Regional Water Board Municipal Regional Permit (MRP), because it will create more than 10,000 square feet of impervious surfaces. The proposed 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. Compliance with applicable regulations will ensure that the proposed pr oject will not result in adverse impacts to water quality during the construction period.

IDLEWILD TOWNHOMES PROJECT CEQA EXEMPTION

CITY OF CUPERTINO

Operational Impacts
As stated previously , the proposed project will be required to comply with the MRP . Furthermore , stormwater from implementation of the proposed project will be directed to the existing stormwater system, in addition to being filtered through the 3,720 square feet of on-site bioretention areas as described in Section 2.4.4.3, Stormwater Management . Therefore, the proposed project will continue to minimize pollutant runoff from the project site and will not result in adverse water quality impacts during operation.

3.4.4.2 GROUNDWATER
The proposed project will connect to the existing water lines on -site and will not use groundwater at the site. Additionally, as described in Section 2.4.4.3, Stormwater Management , the proposed project will include 3,720 square feet of on -site bioretention areas , which will allow water to percolate into the groundwater basin below the project site. Therefore, the proposed project will not deplete groundwater supplies or interfere substantially with groundwater recharge.

3.4.4.3 DRAINAGE PATTERNS
Stormwater runoff from the project site is channeled into a storm drain under Stevens Creek Boulevard.

Stormwater from Cupertino is eventually discharged into San Francisco Bay. As described in Section 2.4.4.3, Stormwater Management, the proposed project includes 3,720 square feet of on -site bioretention areas and will result in a decrease of approximately 26,200 square feet of impervious surfaces . The proposed project will be 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.

Additionally, CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Section 17.04.050(F), which will minimize stormwater runoff:

CMC Section 17.04.050( F), Control Stormwater Runoff Contamination . The project applicant shall demonstrate compliance with Chapter 9.18 (Stormwater Pollution Prevention and Watershed Protection) of the Cupertino Municipal Code, to the satisfaction of the City of Cupertino. All identified stormwater runoff control measures shall be included in the applicable construction documents.

CMC Chapter 9.18 is intended to provide regulations and give legal effect to certain requirements of the NPDES permit, which requires erosion and siltation -control measures, issued to the City. Therefore, compliance with the CMC and Santa Clara Valley Urban Runoff Pollution Prevention Program C.3 requirements will ensure that the proposed project will not substantially alter the existing drainage pattern of the site or area.

3.4.4.4 INUNDATION
The project site is not in a 100-year flood zone or special flood hazard area as mapped by the Federal Emergency Management Agency (FEMA). Additionally, the project site is also not in an area subject to tsunami, seiche, or dam failure inundation. Therefore, the proposed project will not risk release of pollutants due to project inundation.

3.5 CEQA GUIDELINES SECTION 15332(E): UTILITIES AND PUBLIC

SERVICES
For the following reasons, the project site can be adequately served by all required utilities and public services and therefore meets the criteria of CEQA Guidelines Section 15332(e).

The project site is in an urban area already served by all necessary municipal utilities (i.e., stormwater, water, wastewater, solid waste) and public services (i.e., police and fire).

3.5.1 Stormwater
The project site is served by existing stormwater sewer systems, and the proposed project will not require additional or modified stormwater sewer systems. As described in Section 2.4.4.3, Stormwater Management, the proposed project will also implement 3,720 square feet of on-site bioretention areas to reduce or slow stormwater runoff and will result in a decrease of approximately 26,200 square feet of impervious surfaces. Therefore, the proposed project will reduce demand to stormwater infrastructure when compared to existing conditions and will not result in significant impacts to stormwater utilities.

3.5.2 Water
The project site is in the CWS service area. Water service to the project site will be provided by the existing water lines on Stevens Creek Boulevard and East Estates Drive. No new connections will be needed and are not proposed as part of the proposed project. As shown in the water supply evaluation included in Appendix G, Environmental A ssessment, of the Cupertino General Plan, which evaluated the project site being developed at a great er density (80 dwelling units per acre) than what is proposed (2 5 dwelling units per acre), CWS predicts that there will be sufficient water supplies to meet citywide demand through year 2040 during normal, single-dry, and multiple-dry years.54 Furthermore, the project applicant will be required to comply with CMC Chapter 17.04, Standard Environmental Protection Requirements. Specifically, the project

applicant will be required to comply with CMC Section 17.04.050(I)(2), which will ensure adequate water supply and infrastructure:

CMC Section 17.04.050(I)(2), Ensure Adequate Water Supply and Infrastructure. The project applicant shall obtain written approval from the appropriate water service provider for water connections, service capability, and location and layout of water lines and backflow preventers, prior to issuance of the first permit.

This will ensure that the existing system can support the proposed project. Therefore, the proposed project will not result in significant impacts to water utilities.

3.5.3 Wastewater
The project site is in the CSD service area, and wastewater will be treated at SJ/SCWPCP . Wastewater generated by the proposed project will be collected by the existing sanitary sewer main along Stevens Creek Boulevard. As shown in the wastewater evaluation included in Appendix G, Environmental Assessment, of the Cupertino General Plan, which evaluated the project site being developed at a great er density ( 80 dwelling units per acre) than what is proposed (25 dwelling units per acre), CSD ha s sufficient capacity for buildout of the General Plan. As shown, t he increase in wastewater demand due to future potential development from the General Plan is estimated to be approximately 0.41 million gallons per day (mgd). As of 2020, the SJ/SCWPCP i s treating 110 mgd with a permitted capacity of 167 mgd. Therefore, the wastewater treatment facility has a residual capacity of 57 mgd and the addition of 0.41 mgd from implementation of the General Plan buildout is only 0.7 percent of the residual capacity. 55 The project applicant will be required to comply with CMC Chapter 17.04, Standard Environmental Protection Requirements. Specifically, the project applicant will be required to comply with CMC Section

17.04.050(I)(1), which will minimize potential impacts to the sewer system:

CMC Section 17.04.050(I)(1), Manage Wastewater Inflow and Infiltration to Sewer System . Project applicants shall implement the following measures to reduce wastewater flow:
a. The project applicant shall demonstrate, to the satisfaction of the City of Cupertino and Cupertino Sanitary District (CSD) that the 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:
i. Reduce inflow and infiltration in the CSD system to reduce peak wet weather flows, or

ii. 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.
b. The project’s estimated wastewater generation shall be calculated using the current generation rates used by the CSD unless alternative (i.e., lower) generation rates achieved by the project are substantiated by the project applicant based on evidence to the satisfaction of the CSD. c. The project applicant shall obtain a letter of clearance from the Cupertino Sanitary District and provide a copy of the letter of clearance to the City prior to issuance of the first permit.

This will ensure that the existing system can support the proposed project. Therefore, the proposed project will not result in significant impacts to wastewater utilities.

3.5.4 Solid Waste
The City contracts with Recology to provide solid waste collection services to residents in the city . Solid waste is collected by Recology and deposited at the Newby Island Sanitary Landfill in Milpitas. The proposed project site is already served by solid waste services and will continue to be served by Recology under the proposed project. As shown in the solid waste evaluation included in Appendix G, Environmental Assessment, of the Cupertino General Plan, which evaluated the project site being developed at a greater density (80 dwelling units per acre) than what is proposed (25 dwelling units per acre), the Newby Island Sanitary Landfill has sufficient capacity for buildout of the General Plan. As shown , an increase of 8.8 tons per day from implementation of the General Plan buildout would be 0.4 percent of the current residual capacity of Newby Island Sanitary Landfill. 56 The proposed project will not result in an excess of solid waste that will not be able to be accommodated under existing services.

3.5.5 Public Services Providers
The primary purpose of the public services impact analysis is to examine the impacts associated with physical improvements to public service facilities required to maintain acceptable service ratios, response times, or other performance objectives. Public service facilities need improvements (i.e., construction, renovation, or expansion) as demand for services increase. Increased demand is typically driven by increases in population. The proposed project will have a significant environmental impact if it exceeds the

ability of public service providers to adequately serve residents, thereby requiring construction of new facilities or modification of existing facilities.

The proposed project is in an area already served by public service provider s. Through developer impact fees, development of the proposed project will support the City’s public services funds that are used , in part, to maintain City services. Likewise, and pursuant to SB 50, 57 the project applicant will be required to pay the school impact fees required for residential development to offset impacts to the school district. As shown in the public services evaluation included in Appendix G, Environmental Assessment, of the Cupertino General Plan, which evaluated the project site being developed at a greater density (80 dwelling units per acre) than what is proposed (25 dwelling units per acre), impacts to public service providers (fire protection, police, schools, libraries, and parks) were found to be less than significant at General Plan buildout. Therefore, the proposed project will not result in an increase in demand that will prevent public service providers from adequately serving residents.

57 Senate Bill 50 amended California Government Code Section 65995, which contains limitations on Education Code Section 17620, the statute that authorizes school districts to assess development fees within school district boundaries.

4. Exceptions
In addition to analyzing the applicability of CEQA Guidelines Section 15332 (Class 32), this document assesses whether any of the exceptions to categorical exemptions identified in CEQA Guidelines Section 15300.2 (Exceptions) apply to the proposed project. The following analysis compares the criteria in CEQA Guidelines Section 15300.2 (Exceptions) to the project, and concludes, based on substantial evidence, that none of the exceptions are applicable to the project, and that the project is categorically exempt from CEQA pursuant to CEQA Guidelines Sections 15300 and 15332.

4.1 CEQA GUIDELINES SECTION 15300.2(A): LOCATION
Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located – a project that is ordinarily insignificant in its impact on the environment may , in a particularly sensitive environment, be significant. Therefore, these classes are considered to apply to all instances, except where the project may impact an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, State, or local agencies.

The proposed project does not qualify for an exemption under Classes 3, 4, 5, 6, or 11. The project site is in an urban developed area and is not in a sensitive environment. In addition, the proposed project will not result in any impacts on an environmental resource of hazardous or critical concern. Therefore, the exception under CEQA Guidelines Section 15300.2(a) does not apply to the proposed project.

4.2 CEQA GUIDELINES SECTION 15300.2(B): CUMULATIVE IMPACT All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time, is significant.

The project site is in a developed urban neighborhood that is already served by utilities and public services, as well as transportation. As discussed in Section 3.4, CEQA Guidelines Section 15332(d): Traffic, Noise, Air Quality, or Water Quality , the proposed project will not result in significant impacts pertaining to traffic, noise, air quality, or water quality. Any construction effects will be temporary, confined to the project vicinity, and reduced to the extent feasible through compliance with the CM C and applicable regulations.

Therefore, the exception under CEQA Guidelines Section 15300.2(b) does not apply to the proposed project.

4.3 CEQA GUIDELINES SECTION 15300.2(C): SIGNIFICANT EFFECT A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances.

Neither the CEQA Statute nor the State CEQA Guidelines provide a definition of "unusual circumstances." However, the courts have provided guidance in determining what constitutes unusual circumstances. In Berkeley Hillside Preservation et al v. City of Berkeley et al. (2015), the California Supreme Court stated, " A party invoking the [Section 15300.2(c)] exception may establish an unusual circumstance without evidence of an environmental effect, by showing that the project has some feature that distinguishe s it from others in the exempt class, such as its size or location [emphasis added]." This Supreme Court decision established a two-pronged test for determining whether the Section 15300.2(c) exception applies. Under this test, the lead agency must first determine whether an unusual circumstance exists and then, if an unusual circumstance does exist, must apply the fair argument standard to determine whether there is a reasonable possibility that the proposed project would produce a significant effect due to that circumstance.

There are no known unusual circumstances applicable to the project that could result in a significant effect on the environment. The proposed project consists of the demolition of the existing commercial building on the project site and the construction of 55 new residential townhome units and 10 ADUs on a 2.72-acre project site at 10065 East Estates Drive in the central region of the city near the intersection of Stevens Creek Boulevard and Wolfe Road. The proposed project will not result in a change in the existing land use or zoning designations or introduce a new activity to the area that could result in a significant effect on the environment. Therefore, neither the size nor the location of the project site is unusual.

With respect to the existing conditions, a s discussed in Section 2.2, Existing Conditions , One Hour Dry Cleaners operated a dry-cleaning business at 10045 East Estates Drive using PCE as a dry -cleaning solvent between the 1960s and 2010. Due to the presence of PCE, believed to be associated with the former dry - cleaning operations, in soil and soil gas, the project site is listed as an open cleanup program site under the oversight of SCCDEH and is listed on the State Water Quality Control Board’s GeoTracker website. However, the City recognizes that sites subject to redevelopment may contain hazardous materials or contaminated soils are not unusual and, as described in Section 1.2, Standard Environmental Protection Requirements, updated the CMC to include Chapter 17.04, that set forth a uniform set of standards that apply to every project in Cupertino to address hazardous materials, further supporting that the One Hour Dry Cleaners is not an unusual circumstance. The project applicant will be required to comply with CMC Chapter 17.04 Specifically, the project applicant will be required to comply with CMC Section 17.05.050( B) listed below, which will require soil remediation:

IDLEWILD TOWNHOMES PROJECT CEQA EXEMPTION

CITY OF CUPERTINO

CMC Section 17.04.050(B), Hazardous Materials Permit Requirements.

Soil Remediation Required. If a Focused or other Phase II ESA, as required pursuant to Section

17.04.040(B)(1), identifies an unacceptable or a potentially unacceptable health risk, the project applicant shall, depending on the contaminant, contact either the Environmental Protection Agency (EPA), Department of Toxic Substances Control (DTSC), Regional Water Quality Control Board (RWQCB) or local Certified Unified Program Agency (CUPA). The project applicant shall enter into a regulatory agency oversight program with an appropriate regulatory agency, or an established voluntary oversight program alternative with an appropriate regulatory agency, as determined by the City, and follow the regulatory agency’s recommended response actions until the agency reaches a no further action determination, prior to issuance of any permit for a project that allows ground disturbing activity.

With mandatory compliance with CMC Section 17.04.050(B), the proposed project would obtain written clearance from the SCCDEH prior to the issuance of any building permits confirming that the project site has been adequately investigated and remediated for contamination associated with the former dry - cleaning operations and would not have a significant effect on the environment due to site contamination.

Therefore, the exception under CEQA Guidelines Section 15003.2(b) does not apply to the proposed project.

4.4 CEQA GUIDELINES SECTION 15300.2(D): SCENIC HIGHWAYS A categorical exemption shall not be used for a project that may result in damage to scenic resources, including, but not limited to , trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements that are required as mitigation by an adopted negative declaration or certified environmental impact report (EIR).

The proposed project will not affect a resource within a State Scenic Highway. The nearest scenic highway, State Route 9, is over five miles south of the project site. The nearest eligible State Scenic Highway, I-280, is approximately 0.5 miles northeast of the project site, with urban development between.58 The project site is not visible from I -280. Additionally, the project site and surrounding area are already developed.

Therefore, no scenic resources within view of a State Scenic Highway will be altered as part of the project.

4.5 CEQA GUIDELINES SECTION 15300.2(E): HAZARDOUS WASTE SITES A categorical exemption shall not be used for a project on a site that is included on any list compiled pursuant to Section 65962.5 of the Government Code.

California Government Code Section 65962.5 requires the California E nvironmental Protection Agency (CalEPA) to compile, maintain, and update specified lists of hazardous material release sites. CEQA requires the lead agency to consult the lists compiled pursuant to Government Code Section 65962.5 to determine whether a project and any alternatives are identified.59 The required lists of hazardous material release sites are commonly referred to as the “Cortese List” named after the legislator who authored the legislation.

Because the statute was enacted more than 20 years ago, some of the provisions refer to agency activities that were conducted many years ago and are no longer being implemented and, in some cases, the information required in the Cortese List does not exist. Those requesting a copy of the Cortese Lists are now referred directly to the appropriate information resources contained on internet websites hosted by the boards or departments referenced in t he statute, including California Department of Toxic Substance Control’s (DTSC) online EnviroStor database and the State Water Resources Control Board’s (SWRCB) online GeoTracker database. These two databases include hazardous material release sites, along with other categories of sites or facilities specific to each agency’s jurisdiction.

The project site is listed as an open cleanup program site on the State Water Quality Control Board’s GeoTracker website.
60 However, the project site is not included on the Hazardous Waste and Substances Site List (Cortese) pursuant to Government Code Section 65962.5 as of November 2025.61 Additionally, the project site is not listed on any of the following CalEPA’s Cortese List Data Resources:62  List of Hazardous Waste and Substances sites from DTSC EnviroStor database63  List of Leaking Underground Storage Tank Sites from SWRCB’s GeoTracker64

4.6 CEQA GUIDELINES SECTION 15300.2(F): HISTORICAL RESOURCES A categorical exemption shall not be used for a project that may cause a substantial adverse change in the significance of a historical resource.

No historic resources exist in the vicinity of the project site. There is also no known sensitivity for archaeological or paleontological resources on the site. However, the site may contain previously unknown subsurface archaeological and paleontological deposits. The proposed project will comply with Land Use and Community Design Element Policy 2-72 in the General Plan, which requires compliance with City, State, and federal historic preservation laws, regulations, and codes, including laws related to arc haeological resources. In particular, the proposed project will be required to comply with CEQA Guidelines Section 15064.5(e), which specifies procedures to be used in the event of a discovery of Native American human remains on non-federal land. Additionally, CMC Chapter 17.04, Standard Environmental Protection Requirements, identifies standard environmental protection requirements that all construction projects must meet. Specifically, the project applicant will be required to comply with CMC Sections 17.04.050(E)(1),

a. Areas with No Known Cultural Resources. For all projects within areas where there are no known cultural resources, prior to soil disturbance, the project applicant shall provide written verification, including the materials provided to contractors and construction crews, to the City confirming that contractors and construction crews have been notified of basic archaeological site indicators, the potential for discovery of archaeological resources, laws pertaining to these resources, and procedures for protecting these resources as follows:
i. Basic archaeological site indicators that may include, but are not limited to, darker than surrounding soils of a friable nature; evidence of fires (ash, charcoal, fire affected rock or earth); concentrations of stone, bone, or shellfish; artifacts of stone, bone, or shellfish; evidence of living surfaces (e.g., floors); and burials, either human or animal. ii. The potential for undiscovered archaeological resources or tribal cultural resources on site. iii. The laws protecting these resources and associated penalties, including, but not limited to, the Native American Graves Protection and Repatriation Act of 1990, Public Resources Code Section 5097, and California Health and Safety Code Section 7050 and Section 7052. iv. The protection procedures to follow should construction crews discover cultural resources during project-related earthwork, include the following:

1. All soil disturbing work within 25 feet of the find shall cease.

2. The project applicant shall retain a qualified archaeologist to provide and implement a plan for survey, subsurface investigation, as needed, to define the deposit, and assessment of the remainder of the site within the project area to determine whether the resource is significant and would be affected by the project.

3. Any potential archaeological or tribal cultural resources found during construction activities shall be recorded on appropriate California Department of Parks and Recreation forms by a qualified archaeologist. If the resource is a tribal cultural resource, the consulting archaeologist shall consult with the appropriate tribe, as determined by the Native American Heritage Commission, to evaluate the significance of the resource and to recommend appropriate and feasible avoidance, testing, preservation or mit igation measures, in light of factors such as the significance of the find, proposed project design, costs, and other considerations. The archeologist shall perform this evaluation in consultation with the tribe.
b. Areas with Known Cultural Resources. For all projects within areas of known cultural resources as documented in the 2015 General Plan EIR Table 4.4-2, Cultural Resources in the Project Study Area and Vicinity, as subsequently revised, supplemented, or replaced by the City, and the archaeological or tribal cultural resources cannot be avoided, in addition to the requirements in Section E.1.a for all construction projects with ground-disturbing activities, the following additional actions shall be implemented prior to ground disturbance:

4. Exceptions

i. The project applicant shall retain a qualified archaeologist to conduct a subsurface investigation of the project site, and to ascertain the extent of the deposit of any buried archaeological materials relative to the project’s area of potential effects, in consultation with a tribal representative as applicable. The archaeologist shall prepare a site record and file it with the California Historical Resource Information System and the City of Cupertino. ii. If the resource extends into the project’s area of potential effects as determined by the archaeologist, the resource shall be evaluated by a qualified archaeologist to determine if the resource is eligible for listing on the California Register of Historical Resources. If the qualified archaeologist determines that the resource is not eligible, no further action is required unless there is a discovery of additional resources during construction (as required above for all construction projects with ground -disturbing activities). If the qualified archaeologist determines that the resource is eligible, the qualified archaeologist shall identify ways to minimize the effect which the project applicant shall implement. A written report of the results of investigations and mitigations shall be prepared by the qualified archaeologist and filed with the California Historic Resources Information System Northwest Information Center and the City of Cupertino.

CMC Section 17.04.050(E)( 2), Protect Human Remains and Native American Burials . The project applicant shall comply with California Health and Safety Code Section 7050.5 and California Public Resources Code Section 5097.98.
a. In the event of discovering human remains during construction activities, there shall be no further excavation or disturbance of the site within a 100 -foot radius of the remains, or any nearby area reasonably suspected to overlie adjacent remains.
b. The Santa Clara County Coroner shall be notified immediately and shall make a determination as to whether the remains are Native American.
c. If the Santa Clara County Coroner determines that the remains are not subject to his authority, he shall notify the Native American Heritage Commission (NAHC) within 24 hours. d. The NAHC shall attempt to identify descendants (Most Likely Descendant) of the deceased Native American.
e. The Most Likely Descendant has 48 hours following access to the project site to make recommendations or preferences regarding the disposition of the remains. If the Most Likely Descendant does not make recommendations within 48 hours after being allowed access to the project site, the owner shall, with appropriate dignity, reinter the remains in an area of the property secure from further disturbance and provide documentation about this determination and the location of the remains to the NAHC and the City of Cupertino. Alternatively, if the owner does not accept the Most Likely Descendant’s recommendations, the owner or the descendent may request mediation by the NAHC. Construction shall halt until the mediation has concluded.

CMC Section 17.04.050(H), Protect Paleontological Resources During Construction. If paleontological resources are encountered during ground disturbing and/or other construction activities, all construction shall be temporarily halted or redirected to allow a qualified paleontologist, which shall be retained by the project applicant, to assess the find for significance. If paleontological resources are found to be significant, the paleontological monitor shall determine appropriate actions, in coordination with a qualified paleontologist, City staff, and property owner . Appropriate actions may include, but are not limited to, a mitigation plan formulated pursuant to guidelines developed by the Society of Vertebrate Paleontology and implemented to appropriately protect the significance of the resource by preservation, documentation, and/or removal, prior to recommencing activities. Measures may include, but are not limited to, salvage of unearthed fossil remains and/or traces (e.g., tracks, trails, burrows); screen washing to recover small specimens; preparation of salvaged fossils to a point of being ready for curation (e.g., removal of enclosing matrix, stabilization and repair of specimens, and construction of reinforced support cradles); and identification, cataloging, curation, and provision for repository storage of prepared fossil specimens.

With mandatory compliance with CMC Section s 17.04.050(E)(1), 17 .04.050(E)(2), and 17.04.050(H), the proposed project will not result in significant impacts to unknown archaeological, tribal cultural, or paleontological resources. Therefore, the exception under CEQA Guidelines Section 15003.2(f) does not apply to the proposed project.

5. Conclusion
As discussed in Chapter 3, Exemption , of this document, the proposed project meets the criteria for categorically exempt in-fill development projects in CEQA Guidelines Section 15332 and because, as discussed previously, none of the exceptions to the categorical exemptions in CEQA Guidelines Section 15300.2 apply, and it will not have a significant effect on the environment pursuant to CEQA, this analysis finds that a Notice of Exemption is appropriate for the proposed project.

EXECUTIVE SUMMARY

We conducted a phase I environmental site assessment (phase I ESA) for the subject property located at 19610 to 19590 Stevens Creek Boulevard and 10025, 10045, 10051, 10065, and 10075 East Estates Drive in Cupertino, California (the Property). The Property is approximately 2.7 acres in area and is identified by Assessor’s Parcel Numbers (APNs) 369 -06-002, 369-06-003, and 369-06-004.

The Property consists of an approximately 41,000 -square-foot commercial building and associated parking and landscaped areas. Most of the former tenant spaces are vacant, while a furniture store, restaurant, and salon remain on site. Review of historical records indicates that one to three structures were located along the eastern edge of the Property as early as 1897.

Orchards are visible across the Property and surrounding sites in the earliest aerial photograph of the Property from 1939. Between 1956 and 1960, the orchards were felled, and the Property was redeveloped with the present-day commercial building and parking areas. The Property has remained in similar condition since. One-Hour Dry Cleaners operated a dry-cleaning business at 10045 East Estates Drive using tetrachloroethylene (PCE) as a dry-cleaning solvent between the 1960s and 2010, when the dry -cleaning operation converted to using a hydrocarbon -based solvent. We understand that the proposed development for the Property includes 55 high-density residential units (row townhouses).

This assessment included a review of local, state, tribal, and federal environmental record sources, standard historical sources, aerial photographs, fire insurance maps, and physical setting sources. A Property reconnaissance was conducted to observe site use and current conditions, and to check for the storage, use, production, or disposal of hazardous or potentially hazardous materials. Written/oral interviews were conducted with persons knowledgeable about current and past site use.

A review of regulatory databases maintained by county, state, tribal, and federal agencies found no documentation of hazardous materials violations or discharge on the Property and in general, did not identify contaminated facilities within the appropriate ASTM search distances that would reasonably be expected to impact the Property. H owever, the site reconnaissance and records review found documentation and physical evidence of soil and soil gas impairments associated with the past use of the Property.

Several previous environmental investigations have been conducted to evaluate whether the subsurface has been impacted by the historical use of the Property for agriculture and dry cleaning operations. Soil samples were collected at the Property in 2021 and analyzed for agrichemicals (organochlorine pesticides [OCPs], arsenic, and lead), in addition to other constituents. Soil gas samples were collected and analyzed for volatile organic compounds (VOCs). Soil sampling results suggested that shallow soil ha d not been impacted by historical agricultural activities.

However, soil and soil gas have been impacted with chlorinated solvents associated with historical dry cleaning operations.

One-Hour Dry Cleaners is listed as an open cleanup program site (Case ID 2023-17s) under the oversight of Santa Clara County Department of Environmental Health (SCCDEH) and is listed on GeoTracker under global ID T10000021095. Several soil, groundwater, soil gas, indoor air, and sub-slab soil gas investigations have been conducted to evaluate the lateral and vertical extents of the PCE plume and human health risks to building occupants. The majority of PCE impacts are within the back alley behind (west of) the former One -Hour Cleaners tenant space, which is Toll Brothers, Inc. Idlewild Shopping Center

presently vacant. PCE was likely released from dumping mop water out the back door, or leaked from the sanitary sewer. The PCE released at the Property impacts soil and soil gas; there is no indication of free product in the subsurface, and groundwater has not been encountered to the total depth explored (80 feet) during previous investigations. The soil gas plume extends west to the off-site property located at 19620 Stevens Creek Boulevard. The Property owner, Idlewild Tenants in Common (TIC), entered int o a voluntary remedial action agreement (RAA) with SCCDEH on July 31, 2023.

Terraphase Engineering Inc. (Terraphase) prepared a Remedial Action Plan (RAP) for the Property dated September 18, 2023. The RAP proposed implementing soil vapor extraction (SVE) to remedy PCE impacts in the vadose zone beneath the Property and neighboring property to the west. The objective of SVE is to reduce the concentrations of PCE and its breakdown products in the subsurface to a level where a vapor barrier equipped with a passive venting system can mitigate indoor air intrusion of PCE at concentrati ons above residential indoor air environmental screening levels (ESLs)1. The SVE system began operating in June 2024. By December 2024, Terraphase and SCCDEH concluded that SVE had been successful, and that at the current soil gas concentrations, it was appropriate to discontinue active remediation.

The SVE system was shut down in January 2025 to monitor for rebound ; however, SCCDEH opined that the soil gas concentrations had not reached equilibrium. An additional extraction well was installed near the northwest ern corner of the on -site commercial building and has been operating since April 2025. SVE system operation and rebound testing will continue in accordance with SCCDEH requirements.

In addition to the documented on-site PCE release, several nearby historical gasoline service stations, dry cleaners, and the former Vallco Shopping Mall have been evaluated as potential sources of soil gas impacts at the Property. We have not identified nearby releases likely to pose a current or future vapor intrusion risk to the Property. Furthermore, any soil gas impacts that remain at the Property following SVE operation will be mitigated by the installation of vapor intrusion mitigation systems (VIMS) beneath the planned buildings.

Based on the findings of this assessment, no Historical Recognized Environmental Conditions (Historical RECs) were identified for the Property. The following REC and (future) Controlled REC were identified.

• REC: Former One-Hour Cleaners PCE Releases
 Discharges of PCE from former dry cleaning operations have impacted the Property and off-site property to the west. PCE is present in soil gas and, to a lesser degree, soil, at concentrations exceeding residential and/or commercial ESLs 2,3. We understand that Idlewild TIC is responsible for site cleanup prior to transfer of the Property. We recommend continued remediation-related activities of the PCE plume at the Property as appropriate with regulatory oversight.

• Future Controlled REC: Institutional Controls/Deed Restriction  Institutional Controls (ICs) will be required following successful completion of SVE. ICs will likely include an access agreement to allow SCCDEH personnel on Site at any time; funding for SCCDEH oversight; restriction of uses of the Property, restriction of modifications to the Property development without SCCDEH approval, and operation maintenance and monitoring (OM&M) and reporting for the VIMS that is expected to be installed under the planned residential units. A corresponding deed restriction would be recorded for the Property to ensure the systems remain operational. When approved, the ICs/deed restriction will represent a controlled REC for the Property.

Based on our review of regulatory databases and observations during the site reconnaissance, we identified the following business environmental risks (BERs), potential environmental concerns (PECs), and/or de minimis conditions. While not considered to be RECs, these features may pose an environmental concern to the Property. We briefly discuss each feature below.

• A hazardous building materials survey performed in 2023 identified asbestos -containing materials in the on-site commercial building. The cost of asbestos abatement and disposal is considered a BER.

The following data gap and/or data failure were identified during this assessment.

• At the time of report publication, we had not received a response from the Santa Clara County Fire Department (SCCFD).

The data gap and/or data failure identified during this assessment does not affect our conclusions as to the presence of RECs at the Property. We believe that sufficient information has been obtained during our contracted scope of services to evaluate the presence of RECs at the Property. This assessment has revealed evidence of one REC, no Historical RECs, one (future) Controlled REC, and no evidence of significant data gaps, in connection with the Property. We recommend the following.

• The remedial program should be continued under the oversight of SCCDEH. • SVE wells should be destroyed under SCCDEH oversight prior to Property redevelopment. • We recommend engaging a licensed asbestos abatement contractor to develop an asbestos abatement plan and remove asbestos-containing materials prior to building demolition.

We have performed a phase I environmental site assessment of the Property in general conformance with the scope and limitations of ASTM E1527-21 and the standards and practices of the AAI Final Rule (40 CFR Part 312). Any exceptions to, or deletions from t his practice are described in Sections 7.0 and 9.0 of the report.

Please note, the findings from this report are valid until May 9, 2026, one year from the earliest dates of the following components: interviews, review of government records, visual inspections, and declaration of environmental professional. Updates of portions of the assessment may be necessary after a period of 180 days from the earliest dat e of the above components (November 5, 2025).

1.0 INTRODUCTION

1.1 PURPOSE OF PHASE I ENVIRONMENTAL SITE ASSESSMENT

This phase I ESA was performed at the request of Toll Brothers, Inc., the User, for the purpose of environmental due diligence during property acquisition. The objective of this phase I ESA is to identify RECs associated with the Property. As defined in the ASTM Standard Practice E1527-21, a REC is:

(1) the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; (2) the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment.

ASTM Standard Practice E1527-21 provides that identified RECs can be evaluated and classified into Controlled RECs or Historical RECs based on the following definitions.

A Controlled REC is defined as:

…a REC affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place, subject to implementation of required contro ls (for example, activity and use limitations, institutional controls, or engineering controls).

A Historical REC is defined as:

…a previous release of hazardous substances or petroleum products affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the appl icable regulatory authority or authorities, without subjecting the property to any controls (for example, activity and use limitations or other property use limitations).

In addition, while not necessarily related to those environmental issues required to be investigated in this practice, a BER is defined as:

A risk which can have a material environmental or environmentally -driven impact on the business associated with the current or planned use of commercial real estate.

A de minimis condition is defined as:

A condition related to a release that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

2.0 PHYSICAL SETTING

2.1 TOPOGRAPHY, GEOLOGY, AND HYDROGEOLOGY

According to published topographic maps, the Property is relatively level and is situated at approximately Elevation 200 feet (NAVD88). Review of the Geologic Map of the Cupertino and San Jose West Quadrangles, Santa Clara and Santa Cruz Counties (Dibblee and Minch, 2007) found that the Property is underlain by Holocene -aged surficial sediments (Qa.1) consisting of alluvial fan deposits (fine-grained sand, silt, and gravel).

Groundwater has not been encountered on site during previous environmental explorations.

Groundwater is likely present at the Property at depths greater than 100 feet below the ground surface (bgs) (Path Forward Environmental Engineering and Geology, 2021b). Therefore, we reviewed the following sources for groundwater depth and flow direction records for the Property and nearby facilities.

• The Geocheck – Physical Setting Source Summary of the Environmental Data Resources, Inc. (EDR) Radius Map Report (Appendix A)

The site -specific groundwater depth and flow direction were not determined as part of this assessment. Fluctuations in groundwater levels may occur seasonally and over a period of years due to variations in precipitation, temperature, irrigation, and other factors.

2.2 OIL AND GAS

We reviewed the Department of Conservation (DOC), Geologic Energy Management (CalGEM) website and map database to determine if any historical oil and/or gas wells were located within or near the Property (CalGEM, n.d.). No oil or gas wells were mapped on or within 1 mile of the Property.

We reviewed the United States Department of Transportation, Pipeline and Hazardous Materials Safety Administration (USDOT -PHMSA) National Pipeline Mapping System (NPMS) public viewer website for information about petroleum, natural gas, or hazardous liquid storage, processing, or transmission facilities in the vicinity of the Property (USDOT -PHMSA, n.d.). No facilities were mapped on or within ¼ mile of the Property. An active natural gas pipeline maintained by PG&E is located along Stevens Creek Boulevard, along the northern Property boundary. This pipeline would not be expected to pose an environmental concern to the Property.

2.3 INDOOR AIR QUALITY

An evaluation of indoor air quality, mold, or radon was not included as part of the contracted scope of services. The California Department of Public Health (DPH) has conducted studies of radon risks throughout the state, sorted by zip code (California DPH , 2016). Results of the studies indicate that 93 tests have been conducted within the Property zip code, with four tests exceeding the current USEPA action level of 4 picocuries per liter (pCi/L).

As part of this assessment, we conducted a Tier 1 Vapor Encroachment Screen (VES) for the Property in general accordance with ASTM E2600 -22 Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions (ASTM International, 2022). The purpose of the VES is to evaluate whether a vapor encroachment condition (VEC) exists at the Property. A VEC represents the presence of likely presence of vapor-forming compounds (VFCs) in the vadose zone of the Property caused by the release of vapors from contaminated soil and/or groundwater either on or near the Property. We did not identify any on-site releases of petroleum hydrocarbons, but we note that the fuel constituent benzene has been detected in soil gas at the Property (refer to Section 3.0). Additionally, the former on-site dry cleaner is a source of chlorinated VOC impacts in soil and soil gas which creates a VEC for the Property . We also identified several potential petroleum hydrocarbon sources of vapor intru sion within 1/10 mile of the Property and VOC sources within 1/3 mile of the Property : Former Vallco Shopping Center (petroleum hydrocarbon and VOC source; 10123 North Wolfe Road); two gasoline service stations (petroleum hydrocarbon sources; 19550 and 19480 Stevens Creek Boulevard); and two dry cleaners (VOC sources; 19720 and 19705 Stevens Creek Boulevard). These sites are further Toll Brothers, Inc. Idlewild Shopping Center

discussed in Section 4.3.2 and after further review, are not believed to pose a current vapor intrusion risk to the Property.

3.0 PREVIOUS ENVIRONMENTAL REPORTS

The Property was used for agriculture between 1939 and 1956. The existing commercial building was constructed at the Property in 1960. One-Hour Dry Cleaners operated at the Property using PCE as a dry -cleaning solvent between the 1960s and 2010, when the d ry-cleaning operation converted to using a hydrocarbon -based solvent. The dry cleaner was identified as an environmental concern during a phase I ESA conducted by Path Forward Environmental Engineering and Geology (Path Forward , not available for ENGEO’s r eview). The phase I ESA also identified potential environmental contamination from OCPs and metals associated with the former agricultural use of the Property.

This facility is listed as an open cleanup program site (case ID 2023 -17s) under the oversight of SCCDEH, and is listed on GeoTracker under global ID T10000021095. Previous environmental investigations are summarized below.

Path Forward Environmental Engineering and Geology. 2021a. DRAFT Subsurface Investigation Report, Cupertino Retail Center, 10025 -10075 East Estates Drive and 19590 -19610 Stevens Creek Boulevard, Cupertino, California. August 6, 2021.

Path Forward conducted a phase II environmental site assessment (phase II ESA) for the Property in June 2021, to evaluate shallow soil and soil gas conditions for environmental due diligence purposes in support of the planned redevelopment of the Property. The objective was to evaluate shallow soil impacts associated with the former agricultural operations at the Property and evaluate soil gas impacts from the former dry cleaner.

The scope of the investigation included the advancement of seven soil borings (B1 through B7) to a maximum depth of 15.5 feet below the ground surface (bgs). Soil samples were collected at

1.0 and 2.5 feet. Temporary soil gas probes were installed at depth s of 5 and 15 feet bgs in the back alley and around the property boundary, and soil gas samples were collected. A total of 14 soil samples were analyzed for total petroleum hydrocarbons (TPH) as gasoline, diesel, and motor oil (TPH -g, TPH -d, and TPH -mo), V OCs, semi -volatile organic compounds (SVOCs), California Assessment Manual (CAM) 17 Metals, OCPs, polychlorinated biphenyls (PCBs), and asbestos. A total of 14 soil gas samples were analyzed for VOCs and fixed gases.

Soil results were compared to the San Francisco Bay Regional Water Quality Control Board’s (SFBRWQCB’s) residential ESLs 4. Arsenic results were compared to the naturally occurring background concentration of 11 milligrams per kilogram (mg/kg) 5. The soil results indicated that PCE and 4,4’-DDT were detected in several samples above laboratory reporting limits but below residential ESLs. None of the arsenic concentrations in the samples exceeded 11 mg/kg. The OCP and arsenic results suggested that the Property had not been adversely impacted by historical agricultural activities. TPH, SVOCs, metals, PCBs, and asbestos were either not detected above laboratory reporting limits or were detected below the ESLs.

Soil gas results were compared to the SFBRWQCB’s residential subslab/soil gas vapor intrusion human health risk levels6 with an attenuation factor of 0.03. The results indicated that PCE was detected above the ESL of 15 micrograms per cubic meter (µg/m 3) in six samples, at concentrations ranging between 17 µg/m 3 and 20,000 µg/m 3. The maximum concentration was detected in B3 at 15 feet bgs. Chloroform was also detected above the residential ESL of

4.0 µg/m3 in Sample B7 at 5 feet (5.7 µg/m 3). Several samples also exceeded the commercial ESL7 of 67 µg/m3 for PCE. Path Forward calculated the cumulative vapor intrusion cancer risks and noncancer hazard indices for each soil gas sample. The highest estimated cancer risk was estimated to be 1.3x10-3 in Sample B3 at 15 feet, above the 1 to 100 per million (1×10-6 to 1×10-4) risk management range. The highest estimated non-cancer index was estimated to be 14, above the threshold value of 1.

Path Forward concluded that the extent of PCE in soil gas is mostly limited to the northwestern portion of the Property, and noted that based on the cancer risk, a response action (vapor mitigation and/or source remediation) was warranted. Path Forward rec ommended that groundwater samples should be collected near the locations of elevated soil gas concentrations to assess if PCE has impacted groundwater; and that the risk to current occupants from PCE vapor intrusion should be evaluated. Path Forward recommended that the Property owner submit the report to the local regulatory agency for review.

Path Forward Environmental Engineering and Geology . 2021b. DRAFT Additional Investigation Report, Cupertino Retail Center, 10025 -10075 E Estates Drive and 19610 Stevens Creek Boulevard, Cupertino, California. October 1, 2021.

Path Forward conducted an additional investigation in September 2021 to characterize subsurface conditions and determine if PCE had impacted groundwater. The scope of the investigation included the advancement of three borings (B8, B9, B9A) along the northern portion of the Property (B9A was a step -out boring advanced due to refusal at B9). Path Forward additionally reviewed off-site (downgradient) soil gas data. During drilling, borings were screened for VOCs using a photoionization detector (PID).

During the investigation, the highest PID readings were detected in Boring B8 at 15 feet bgs and decreased with depth. Path Forward opined that a secondary PCE source in groundwater was unlikely to be present based on this trend. All borings encountered re fusal between 72 and 97 feet bgs, and did not encounter groundwater.

During their evaluation of off-site properties, Path Forward reviewed available data for the Vallco Shopping Mall. Details regarding this site are discussed in Section 4.3.2.

Path Forward concluded the following.

• Shallow groundwater is not present within the upper 100 feet of the Property. • Based on PID results and off -site deep soil gas samples, a secondary source of PCE is unlikely to be present at depth.

• The presumed downgradient extent of PCE at the Property is generally defined by off -site data collected during investigations of the former Vallco Mall.

Path Forward Environmental Engineering and Geology . 2022. DRAFT Regulatory Path for Remediation, Cupertino Retail Center, 10025-10075 E Estates Drive and 19610 Stevens Creek Boulevard Cupertino, California. Memorandum from David A Grunat, P.G., C.H.G. (Path Forward) to Deke Hunter (Hunter Storm, LLC). February 25, 2022.

Path Forward provided a memorandum dated February 25, 2022, to summarize previous environmental investigations conducted at the Property and to provide a summary of the anticipated regulatory path for remediation present at the Property.

Path Forward recommended that results of previous investigations be presented to an appropriate regulatory agency for review and development of next steps. Path Forward recommended SCCDEH as the most appropriate regulatory agency, as SCCDEH was currently overseeing two adjacent PCE release sites (Vallco Town Center and 19720 Stevens Creek Boulevard). Path Forward noted that additional site characterization would likely be required.

Path Forward indicated that as the Property was anticipated to undergo redevelopment, it is likely that the most appropriate and financially efficient remedial action would be the excavation of approximately 1,200 cubic yards of contaminated soil following building demolition. Excavated soil would be loaded directly into haul trucks and transported to an appropriate disposal facility.

Soil samples would be collected to confirm that the remedial excavation successfully removed the PCE-impacted soil.

Path Forward also indicated that residual PCE in soil gas would likely remain present for some time until it could naturally attenuate below regulatory action levels. During that period, the SCCDEH could require ongoing monitoring of soil gas to demonstrat e that concentrations are decreasing following the excavation. Additionally, buildings constructed in this area would require VIMS incorporated into the building slabs, which would require ongoing OM&M. Finally, a deed restriction for the Property that inc ludes ongoing OM&M would likely be required to ensure the systems remained operational.

Terraphase Engineering. 2022a. Indoor Air and Soil -Gas Sampling Results, 10025, 10045, and 10051 East Estates Drive, Cupertino, California. May 11, 2022.

Terraphase Engineering (Terraphase) conducted an investigation of the Property in April 2022 to evaluate the vapor intrusion risk in the former dry cleaner, watch repair shop, and current Chinese grocery store. The scope of the investigation included the collection of indoor air and sub-slab soil gas samples from three units: the dry cleaner (10045 East Estates Drive), watch repair shop (10025 East Estates Drive), and Chinese grocery store (10051 East Estates Drive).

Results of the indoor air samples were compared to the SFBRWQCB commercial/industrial indoor air ESLs8. The results indicated that PCE was not detected above the ESL of 2 µg/m3. However, benzene was detected above the indoor air ESL of 0.42 µg/m 3 in the sample collected from the former watch repair shop (1.4 µg/m 3). Terraphase concluded that the detection of benzene was not likely due to vapor intrusion; rather, more likely due to in-house chemicals.

Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 11 June 11, 2025

The sub-slab soil gas results were compared to the sub-slab/soil gas commercial ESLs. The PCE concentrations reported in the samples collected from the former watch repair shop, dry cleaner, and just outside the Chinese grocery store were 120 µg/m3, 79 µg/m3, and 99 µg/m3, respectively.

All concentrations exceeded the commercial/industrial soil gas ESL of 67 µg/m3.

Terraphase provided the following conclusions.

• The PCE release only impacts soil and soil gas. The bulk of PCE is present within the back alley. PCE was likely released from dumping mop water out the back door or leaked from the sanitary sewer.
• The PCE detections in the soil samples collected at 1 foot and 2.5 feet bgs from Boring B4 (Path Forward, 2021a), located in the far northern end of the site adjacent to Stevens Creek Boulevard, likely represent a sewer leak or migration through utility trench bedding sand. • Terraphase agreed with Path Forward that it is unlikely for PCE to impact groundwater due to the depth to groundwater and clay layers encountered during Path Forward’s previous investigation between 25 to 80 feet in B8 and 45 to 65 feet in B9 (Path Forward, 2021a).

At the time of publication of Terraphase’s report, the former dry cleaner and watch repair shop had been vacated; hence, there was no risk at the time. Terraphase provided the following recommendations.

• Terraphase recommended that epoxy coating should be installed on the concrete slabs in the former dry cleaner and watch repair shop if the dry cleaner and watch repair shop units were to be occupied in the future. The PCE detection in the grocery store (0.13 µg/m3) represented a risk of 7×10-8 under a commercial/industrial scenario. • Terraphase disagreed with Path Forward’s conclusion that PCE could be remediated by excavation of 1,222 cubic yards of soil. Terraphase noted that the vertical extent of contamination was not sufficiently delineated; the 15 -foot samples collected during Pa th Forward’s 2021 investigation reported higher PCE concentrations than the shallow samples.

If remedial action was warranted, Terraphase recommended SVE, which was more cost effective.
• Terraphase noted that the need for remediation was questionable, as the threat to groundwater was minimal, and the pathway between future residential receptors and impacted soil could be eliminated (based on site development plans included on the figures in Path Forward’s (2021b) report, which showed the bulk of the impacted soil would be beneath parking lots). Terraphase noted that based on the extent of the plume, vapor barriers may need to be installed beneath Buildings 1 and 3 of the proposed developmen t; however, extensive remedial actions did not appear to be warranted. • The highest concentration of PCE detected in soil gas at the Vallco site was 5,890 µg/m 3 in sample SV -14N. Terraphase noted that it is highly unlikely that the PCE release at the Property crossed Stevens Creek Boulevard and impacted the Vallco site. As groundwater was not a potential pathway, the PCE would have to reach the Vallco site throug h either soil gas migration or a preferential pathway. Based on the demonstrated attenuation of PCE in soil gas between the release area (behind the dry cleaner) and samples collected at the north of the Property, it was unlikely that PCE could migrate in soil gas across Stevens Creek Boulevard at the concentrations observed. Additionally, Terraphase concluded that transport through the sanitary sewer was unlikely, as th e Property sanitary sewer drains to a 12 -inch sewer main in Stevens Creek Boulevard that drains to the east, away from the Vallco site.

Terraphase. 2022b. Soil-Gas Investigation Report, 10025-10075 East Estates Drive, Cupertino, California; August 16, 2022.

Terraphase conducted an additional investigation in July 2022 to evaluate the current concentrations at the former dry cleaner unit and the extent of PCE migration in soil gas. The scope of the investigation included installation and sampling of three perm anent and one temporary nested soil vapor probes in the former dry cleaner unit, near the western site boundary, and on the adjacent property to the west. Two triple-depth nested borings (B-11 and B-12) were installed with probe depths of 5, 15, and 25 fee t bgs in the alley behind the dry cleaner. One dual-depth nested boring (B-10) was installed within the dry cleaner with probe depths of 5 and 10 feet bgs. One temporary dual-depth nested boring (B-13) was installed on the neighboring site to the west of the Property with probe depths of 7 and 10 feet.

The sample results indicated that the highest concentration of PCE detected was 30,000 µg/m 3 in the 10-foot sample collected from inside the former dry cleaner (B-10). The PCE concentrations from samples collected in the back alley were consistent with Path Forward’s previous results.

PCE was non -detect in the 25 -foot sample collected from Boring B-12; however, the 25 -foot sample collected from Boring B-11 contained a PCE concentration of 5,700 µg/m3.

Terraphase concluded that PCE had migrated through the sand in most of the borings between 15 and 25 feet bgs to the adjacent property to the west. PCE was detected in the 15-foot sample collected from B-13 at a concentration of 7,100 µg/m3. However, the shallow PCE concentration within sample B-13 was below commercial screening levels.

Terraphase concluded that the PCE released at the Property impacts only soil and soil gas; there is no indication of free product in the subsurface. PCE had migrated westward beneath the adjacent commercial property at concentrations above the commercial E SLs; however, Terraphase noted that ESLs are intended to be conservative. Terraphase recommended that SVE be implemented to remediate soil vapor concentrations on site and off site. Terraphase recommended a 300-cubic-feet-per-minute SVE system. Terraphase also opined that removal of impacted soil is not economically feasible, as the impacts extend to 25 feet bgs.

Terraphase. 2022c. Soil -Vapor Investigation and Soil -Vapor Extraction Pilot Test Report, 10025-10075 East Estates Drive, Cupertino, California; September 6, 2022.

Terraphase prepared an additional investigation report dated September 6, 2022 , to summarize the previous investigations conducted by Path Forward and Terraphase, and to provide recommendations for additional sampling. The report also includes a work plan for additional soil gas investigations at the neighboring property and a pilot scale test of SVE at the Property.

Terraphase noted that although the levels of contamination may not, under a risk-based analysis, require remediation, the Property owner has decided to conduct remediation because the Property is for sale and because the soil gas plume extends beneath the neighboring property to the west. The following scopes of work were recommended as part of the work plan.

Additional Air Sampling

Terraphase recommended that three indoor air samples and one outdoor ambient air sample be collected from the neighboring building to the west of the Property (19620 Stevens Creek Boulevard). Prior to sampling, the building would be screened for indoor air sources and a building survey form would be completed.

Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 13 June 11, 2025

Additional Nested Soil Gas Monitoring Point Installation and Sampling

Terraphase recommended that three permanent, triple -nested soil vapor monitoring wells (B-14 through B -16) be installed at the neighboring property to the west of the Property, to facilitate the collection of soil gas samples and for monitoring of vacuum r esponses during SVE pilot testing to evaluate the effective vacuum radius of influence.

SVE Pilot Test Program

Terraphase proposed a SVE pilot test to evaluate the effectiveness of SVE as a remedy to reduce concentrations of PCE in soil gas at the Property and neighboring site to the west, to below the commercial/industrial ESLs, and to evaluate SVE design paramete rs useful for full-scale design and technical feasibility under site-specific conditions. The proposed scope of the SVE pilot test included installing one, 6 -inch-diameter PVC SVE extraction well near the back door of the dry cleaner. The well would be scr eened in a layer of gravel from 13 to 23 feet bgs, and soil vapor would be extracted to evaluate several SVE parameters.

Terraphase. 2023a. Soil -Vapor Extraction Pilot -Scale Test Work Plan, 10025, 10045, and 10051 East Estates Drive, Cupertino, California. June 20, 2023.

Terraphase prepared a work plan for an SVE pilot -scale study dated June 20, 2023. The work plan expanded upon the recommendations provided in the pilot test report (Terraphase, 2022c).

The scope of work completed is discussed below.

Terraphase. 2023b. Preliminary Results of the Soil Vapor Extraction Pilot Test Conducted at the Idlewild Shopping Center, 10025-10075 East Estates Drive, Cupertino, California. August 4, 2023.

Terraphase prepared a technical memorandum to summarize the preliminary results of the pilot-scale SVE test. Terraphase conducted a 120 -hour pilot-scale test of SVE in the alleyway behind the former dry cleaner between July 18 and July 23, 2023.

Terraphase installed the extraction well, SVE -01, in the alleyway. The well contained a 4-inch-diameter pipe screened between 7 and 23 feet bgs. A trailer -mounted SVE system was installed across the alley from SVE-01. The system is equipped with a variable frequency drive (VFD) controlling a blower capable of producing an air maximum flow rate of 190 standard cubic feet per minute at 190.5 inches of water column (in H 2O)/14 inches of mercury (in Hg) vacuum.

The off-gases from the SVE well are scrubbed in two 300 -pound canisters of granular activated carbon (GAC) arranged in series.

The soil gas concentrations generally indicated that PCE concentrations decreased in each well.

As part of the off-site investigation, Terraphase installed two Vapor Pins (SV -7 and SV-8) in the sidewalk adjacent to the building of the Property, approximately 70 feet from SVE -01. The PCE results were non-detect for SV-7 and 11 µg/m3 for SV-8.

Terraphase. 2023c. Remedial Action Plan, 10025 -10075 East Estates Drive and 19590 -19610 Stevens Creek Boulevard, Cupertino, California. September 18, 2023.

Terraphase prepared a RAP for the Property. The purpose of the RAP was to remedy PCE impacts in the vadose zone beneath the Property and neighboring property to the west. The objective was to reduce the concentrations of PCE and its breakdown products in the subsurface Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 14 June 11, 2025

to a level where a vapor barrier equipped with a passive venting system can mitigate indoor air intrusion of PCE at concentrations above residential indoor air ESLs, when combining the total risk from each detected compound in shallow soil gas. The initial remedial goal was to reduce PCE concentrations to below 460 µg/m 3 in shallow soil gas, based on an attenuation factor of 1,000 for a vapor barrier and passive venting system.

Terraphase noted that the radius of influence (ROI) determined in the SVE pilot study was 80 feet.

Given this effective radius, the pilot-scale SVE system would be able to reach the known extents of the VOC plume under the Property and neighboring property to the west.

The preliminary remedial design included the following: permitting requirements, an OM&M plan, summary of design details, performance monitoring metrics, system shutdown conditions, and contingency actions. Terraphase also noted that ICs would be required following completion of SVE. ICs will likely include the following.

• An access agreement to allow SCCDEH personnel on site at any time. • Funding for SCCDEH oversight.
• OM&M and reporting for the vapor barrier that is expected to be installed under the planned residential units.

ENGEO. 2023a. Phase I Environmental Site Assessment, Idlewild Shopping Center, 19610 to 19590 Stevens Creek Boulevard and 10025, 10045, 10051, 10065, and 10075 East Estates Drive, Cupertino, California. October 25, 2023. Project No. 22934.000.001.

We prepared a phase I ESA for the Property dated October 25, 2023. At the time of the assessment, the Property consisted of an approximately 41,000-square-foot commercial building and associated parking and landscaped areas.

Based on the findings of the assessment, no Historical RECs were identified for the Property. The following REC and (future) Controlled REC were identified:

• REC: Former One-Hour Cleaners PCE Releases
 Discharges of PCE from former dry cleaning operations have impacted the Property and off-site property to the west. PCE is present in soil gas and, to a lesser degree, soil, at concentrations exceeding residential and/or commercial ESL s. We understand that Idlewild TIC is responsible for site cleanup prior to transfer of the Property. We recommended continued remediation-related activities of the PCE plume at the Property as appropriate with regulatory oversight.

• Future Controlled REC: Institutional Controls/Deed Restriction  ICs will be required following successful completion of SVE. ICs will likely include an access agreement to allow SCCDEH personnel on Site at any time; funding for SCCDEH oversight; and OM&M and reporting for the vapor barrier that is expected to be instal led under the planned residential units. A corresponding deed restriction would be recorded for the Property to ensure the systems remain operational. When approved, the ICs/deed restriction will represent a Controlled REC for the Property.

Based on our observations during the site reconnaissance, we also identified the following PEC, not considered to be a REC.

Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 15 June 11, 2025

• During the site reconnaissance, several wells observed were missing bolts or gaskets. The Property owner should be alerted, and these features should be repaired to maintain the integrity of the wells and ensure that they do not act as a pathway for stormwater to enter the subsurface.

We recommended the following.

• The proposed remedial program should be continued under the oversight of SCCDEH. • Wells with missing bolts and gaskets should be repaired to maintain the integrity of the wells and ensure that they do not act as a pathway for stormwater to enter the subsurface.

ENGEO. 2023b. Environmental Peer Review, Idlewild Shopping Center, 19610 to 19590 Stevens Creek Boulevard and 10025, 10045, 10051, 10065, and 10075 East Estates Drive, Cupertino, California. November 30, 2023. Project No. 22934.000.001.

We prepared an environmental peer review of previous environmental reports for the Property dated November 30, 2023, and provided review comments. We generally agreed with the findings stated in Path Forward’s and Terraphase’s reports, including the characterization of PCE impacts and the conclusion that former dry cleaning activities likely had not affected the former Vallco site.

We disagreed with excavation as a sole remedy but supported Terraphase’s recommendation for SVE and targeted soil excavation(s).

We noted that benzene had been detected in soil gas above the residential ESLs and noted that SCCDEH may consider benzene a contaminant of concern. We also noted that indoor air sampling had not been completed at the neighboring property as recommended, and requested clarification.

The SVE pilot test lacked key data, and we recommended including boring logs, operational metrics, and updated plume maps. We also advised further soil sampling to define the depth of PCE impacts to soil and assess sewer line contributions.

We also questioned the proposed remediation timelines and suggested clarifying the SVE operational schedule and regulatory review periods. Lastly, we noted that SCCDEH may require site-specific attenuation factors and active VIMS, and we agreed that institutional controls and a deed restriction will likely be needed post-remediation.

Terraphase. 2024a. Technical Memorandum, Idlewild Soil Vapor Extraction (SVE) System Status Update. August 12, 2024.

Terraphase prepared a status update of the SVE system that began operating in June 2024.

Terraphase reported that concentrations of PCE in the SVE well influent had decreased by more than a factor of 10 since operation began. PCE concentrations in the monitoring wells had similarly decreased. Terraphase concluded that the system was operating effectively.

Terraphase. 2024b. Soil Vapor Extraction Operations, 10025 -10075 East Estates Drive and 19590-19610 Stevens Creek Boulevard, Cupertino, California. December 4, 2024.

Terraphase prepared a report on SVE system progress which included the following.

• A gridded soil sampling program in the former dry cleaner in September 2023. • The installation of one new soil gas monitoring point (B-14). • Six rounds of soil gas/SVE system monitoring.

Terraphase concluded the following:

• No significant “hot spot” of PCE was identified in soil beneath the former dry cleaning tenant space. The source of PCE in soil vapor at the Property was likely incidental releases of mop water containing PCE released to the environment through leaks in the sanitary sewer. • The extent of PCE in soil vapor has been adequately characterized in all directions from the likely release location. The depth of PCE impacts has been adequately characterized. • The SVE remediation has been successful. Concentrations of PCE in soil gas have fallen by almost two orders of magnitude at location B -10 inside the former dry cleaner unit. Other monitored locations throughout the radius of influence have also seen significant reductions.

Terraphase concluded that at the current soil gas concentrations, it was appropriate to discontinue active remediation. Residual PCE concentrations would be managed through the mitigation measures planned for the future Property development. • Terraphase recommended discontinuing the SVE system and initiating rebound testing to assess if the effect of SVE on the PCE concentrations in the subsurface was permanent.

SCCDEH. 2025a. Letter, One-Hour Dry Cleaners, 10045 East Estates Dr., Cupertino, CA 95014, APN: 369-06-22. Site Cleanup Program Case No. 2023-17s, GeoTracker ID No. T10000021095.

January 17, 2025.

SCCDEH issued a letter to the Property owner summarizing their review of Terraphase’s (2024b) report. SCCDEH agreed it was acceptable to discontinue the SVE system operation and initiate rebound testing but required changes to the scope of testing.

Terraphase. 2025. One -Month Soil -Vapor Extraction (SVE) Rebound Testing Report, 10025-10075 East Estates Drive and 19590 -19610 Stevens Creek Boulevard, Cupertino, California. March 12, 2025.

The SVE system was shut down on January 23, 2025, to monitor for rebound. Terraphase prepared a report to summarize the rebound testing results. Terraphase noted that in general, PCE concentrations had stabilized in the wells sampled. Terraphases noted that Idlewild TIC was not requesting site closure at the time. The future housing developer would be installing VIMS under the future structures and would continue to monitor the subsurface under SCCDEH oversight. Terraphase opined that PCE concentrations in the subsurface were well below levels where a properly installed VIMS would protect future site occupants. Terraphase also recommended abandonment of the sanitary sewer behind the former dry cleaner and opined that this would remove residual PCE source material.

Terraphase opined that the SVE system had removed as much PCE mass from the subsurface as was practical, and recommended decommissioning the SVE system, as continued operation was unlikely to result in significant further removal from the subsurface.

SCCDEH. 2025b. Letter, One-Hour Dry Cleaners, 10045 East Estates Dr., Cupertino, CA 95014, APN: 369-06-22. Site Cleanup Program Case No. 2023-17s, GeoTracker ID No. T10000021095.

April 3, 2025.

SCCDEH issued a letter summarizing their review of Terraphase’s (2025) report. SCCDEH did not agree with Terraphase’s recommendation that the SVE system could be shut down because they did not believe that the soil gas concentrations had reached equilibriu m. SCCDEH opined that in order to demonstrate that the soil gas concentrations had reached equilibrium, the rebound monitoring period should be at least 6 months.

On March 31, 2025, SCCDEH received an email from Terraphase stating that the SVE system would be restarted and an additional SVE well would be installed and connected to the existing system. SCCDEH noted that this decision was counter to Terraphase’s previous conclusions and recommendations. SCCDEH required quarterly remediation progress reports documenting the operational parameters of the system.

We note that the SVE system was restarted on April 4, 2025. During our reconnaissance of the Property on June 3, 2025, we observed the second SVE well and operation of the SVE system.

As of the publication of this report, n o additional reports documenting the SVE progress or sampling results have been uploaded to GeoTracker.

4.0 RECORDS REVIEW

4.1 PROPERTY RECORDS

4.1.1 Title Report/Ownership

ASTM Standard Practice E1527 -21 requires a review of title records dating back to 1980. A Preliminary Title Report (PTR) lists recorded land title details, ownership fees, leases, land contracts, easements, liens, deficiencies, and other encumbrances attac hed to or recorded against a property. Laws and regulations pertaining to land trusts vary from state to state and the detail of information presented in a PTR can vary greatly by jurisdiction. As a result, we utilize a PTR, when provided to us, as a suppl ement to other historical record sources. We assume that any environmental liens, activity and use limitations (AULs), deed restrictions, and/or institutional controls for the Property are noted in the PTR.

A PTR for the Property, prepared by Chicago Title Company and dated May 29, 2025 , was provided for our review. The Property title is vested in the following entities: Joseph Nacy Castello; Rosalie Castello Flores; Tamara M. Foglesong; Jennifer Castello; Rick Costello II; Victor M.

Castello; Gina C. Wagner; Geno I. Castello and Victoria M. Castello; Rosalyn J. Castello; Ryan Andersen; Cara Clover Borromei; Danica Cavigliano; and Nicolas Cavigliano.

No references to environmental liens, AULs, deed restrictions, and/or institutional controls were noted. However, the PTR states that there are three monitoring wells located on the Property with no recorded agreements. Several soil gas extraction and monitoring wells associated with SVE Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 18 June 11, 2025

are located on the Property. These wells should be destroyed prior to Property redevelopment.

This report is included in Appendix B.

4.1.2 Environmental Liens and Activity and Use Limitations

The PTR did not identify environmental liens or AULs associated with the Property. In addition, a questionnaire completed by the User (Appendix C) indicated that they are not aware of any environmental cleanup liens recorded against the Property.

We reviewed two engineering control (EC) and IC registries for environmental liens or AULs associated with the Property: EnviroStor, a website maintained by DTSC, and GeoTracker, a website maintained by SWRCB. No records of environmental liens or AULs were noted. However, we anticipate that a deed restriction will be recorded on the Property following completion of SVE and installation of VIMS.

4.2 HISTORICAL RECORD SOURCES

The purpose of the historical record review is to identify uses or occupancies of the Property and surrounding areas that are likely to have led to RECs on the Property.

4.2.1 Historical Topographic Maps, Aerial Photographs, and Sanborn Maps

We reviewed historical USGS topographic maps and aerial photographs for discernible changes to the Property. EDR provided the following maps and photographs, presented in Appendices D and E. No Sanborn fire insurance maps were available for the Property; t he search report is presented in Appendix F.

Sanborn Maps N/A

In the 1897 topographic map, the Property is depicted as undeveloped. Stevens Creek Boulevard is located in its present-day alignment north of the Property. A dirt road and structure extend south from Stevens Creek Boulevard, adjacent to the eastern side of the Property. Calabazas Creek is depicted approximately 1/8 mile southeast of the Property. In the 1939 aerial photograph, orchards are located across the Property and surrounding sites. The dirt road and three structures (homesteads) appear to be either adjacent to the current Property boundary or within the eastern side of the Property. The Property and surrounding areas appeared in similar condition until the late 1950s. Between 1956 and 1961, the orchards were felled and the Property was redeveloped with the present-day commercial building and parking areas. The Property has appeared in similar condition since.

The remaining agricultural areas around the Property were redeveloped into commercial uses between the early 1960s and early 1980s. The gasoline service station adjacent to the east of the Property across East Estates Drive was constructed between 1956 and 1961. Residential developments were constructed south of the Property. The former Vallco shopping center was Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 19 June 11, 2025

constructed between 1968 and 1974. Between 1974 and 1982, the commercial shopping center to the west of the Property was constructed. The Vallco shopping center was demolished between mid-2019 and early 2020. Recent aerial imagery shows that grading has begun on the Vallco redevelopment.

Adjoining and nearby properties of potential environmental concern are discussed below.

Former Vallco Shopping Center – 10123 North Wolfe Road

The former Vallco Shopping Mall, located between approximately 120 to 2400 feet north-northeast of the Property, is listed in the AST, CA FID UST, CERS, CHMIRS, CORTESE,

CPS-SLIC, CUPA LISTINGS, ECHO, E MANIFEST, FINDS, HAZNET, HIST CORTESE, HIST LUST, HIST UST, HWTS, LUST, RCRA NONGEN/NLR, RCRA -SQG, SWEEPS UST, and UST FINDER RELEASE databases sear ched by EDR. The Vallco Shopping Mall operated from 1979 to 2018, and is divided into the western portion (west of North Wolfe Road) and the eastern portion (northeast of North Wolfe Road and Vallco Parkway). We discuss the western and eastern sites below.

Western Vallco Site:

One closed leaking underground storage tank (LUST) case (Sears Automotive Center, GeoTracker ID T0608552828) and one open cleanup program site ( CPS) case (Vallco Town Center, GeoTracker ID T10000017167) are associated with the western Vallco Site. The LUST case pertains to the removal of six underground storage tanks (USTs) in 1985 and subsequent soil sampling and removal.

The CPS case pertains to investigations of PCE release(s). The source is not known due to the many tenants of the mall. WSP conducted a soil gas investigation at the Vallco facility in 2021 which included an evaluation of whether the Idlewild site may be contributing to PCE in soil gas at Vallco by sampling along the southern Vallco site boundary (WSP, 2021). WSP concluded that it was unlikely that the PCE release at the Property contributed to elevated concentrations at Vallco. Terraphase also evaluated WSP’s findings and opined that it was unlikely that PCE could migrate in soil gas across Stevens Creek Boulevard at the concentrations observed at Vallco.

In 2023, as part of redevelopment of the western Vallco Mall site, soil was excavated to a depth of 15 feet for the construction of underground parking, and additional recent targeted excavations were conducted to remove soils impacted with PCBs, TPH, pesticides, and metals. Additionally, a PCE hot spot was excavated to a depth of 20 feet (WSP, 2023) . The 2024 Updated Site Management Plan prepared by EKI provides recent soil and soil gas data showing that several VOC plumes remain in soil gas at the western Vallco Mall site after removal, though concentrations have decreased since pre-excavation. Generally, the plumes are confined to the western Vallco Mall site and contain concentrations of VOCs within the same order of magnitude or one order of magnitude higher than the residential soil gas ESLs , and below concentrations observed at the Property . No further remediation is required or planned at Vallco. We do not consider this site a potential source of petroleum hydrocarbon or VOC impacts to the Property, and vice-versa.

Eastern Vallco Site:

One closed LUST case (J.C. Penney, GeoTracker ID T0608500770) and one open CPS case (East Vallco Mall Site, GeoTracker ID T10000020648) are associated with the eastern site. The eastern Vallco site is in the early stages of redevelopment and investigation. Because this site is situated east of the western Vallco Mall site and northeast of the Property, any impacts from the eastern Vallco site would impact the western Vallco before the Property. Due to the distance and location of the eastern Vallco site, we do not consider this site a potential source of vapor impacts to the Property.

Th is site is associated with two closed LUST cases on GeoTracker: Tosco #11220 (global ID T0608575840) and Mobil (global ID T0608500926).

According to the case summary available on GeoTracker for the Mobil case , in 1985, a loss of 1,800 gallons of product was identified through inventory reconciliation. The USTs were removed in 1985 and soil investigations were completed in the UST area to 120 feet bgs. Very low levels of contamination were detected and groundwater was not encountered. Santa Clara Valley Water District (SCVWD) issued a case closure/no further action letter on March 15, 1996.

In April 2001, free product was encountered in a soil boring . Extensive additional investigation and remediation was subsequently conducted. In May 2012, verification groundwater monitoring commenced. The site was granted case closure by SCCDEH on September 23, 2014. Based on distance and the remedial actions implemented at this facility, this facility would not be expected to pose a concern to the Property.

Shell Automotive/Jiffy Lube #2355/Allan Domash – 19480 Stevens Creek Boulevard

This gasoline service station/Jiffy Lube site, located approximately 417 feet east of the Property, is listed in the LUST, HIST LUST, CORTESE, HIST CORTESE, CERS, AST, CERS HAZ WASTE, CA FID UST, CERS TANKS, CUPA LISTINGS databases searched by EDR. This facility is also listed as a closed LUST case on GeoTracker under case ID T0608501269.

According to the case closure summary/no further action letter, one 10,000-gallon gasoline UST, two 6,000-gallon gasoline USTs, three 12,000-gallon gasoline USTs, and one 550 -gallon waste oil UST were removed from the site between 1987 and 1990. Soil vapor extraction was performed at the site from February to August 1992, and four consecutive quarters of groundwater monitoring were conducted after shutdown of the SVE system. Based upon the results of source removal, remedial actions performed, and verification monitoring, the extent of soil contamination was defined, and groundwater did not appear to be impacted, and SCVWD issued case closure on September 30, 1994. Based on distance and the case closure status, this facility would not be expected to pose a concern to the Property.

One-Hour Photo Service/Holiday Cleaners of America – 19720 Stevens Creek Boulevard

This former photo developing facility and former dry-cleaning facility, located approximately 466 feet west of the Property, is listed in the CERS, CPS -SLIC, CUPA LISTINGS, DRYCLEANERS, EMI, FINDS databases searched by EDR. This facility is also listed as a cleanup program site on GeoTracker under case ID T100000169 70, with the status open – assessment and interim remedial action as of April 1, 2021.

The site owner entered into a voluntary remedial action agreement with SCCDEH on April 1, 2021. According to the Corrective Action Work Plan (CAP) (WSP, 2022), the southwestern area of the site is impacted by PCE in soil gas associated with historical dry cleaning operations.

In September 2019 and January 2020, samples of soil gas, sub -slab vapor, and indoor air were collected to evaluate the potential for vapor intrusion from VOCs. Analytical results revealed that PCE was detected in sub-slab vapor samples (from 37 to 1,500 µg/m 3) and in soil gas samples (from 1.68 to 1,050 µg/m 3). Furthermore, PCE was detected in indoor air samples (from 1.15 to

2.64 µg/m 3). In Sept ember 2020, WSP performed additional sub -slab vapor and indoor air sampling and analyses. The results indicate that the PCE impacts to soil gas are concentrated in the southwestern area of the site and do not appear to extend easterly beyond the site boundary (towards the Property). Therefore, this facility is not expected to pose a concern to the Property.

Wardrobe Custom Cleaners/Minuteman Press/Mel’s Cleaners – 19705 Stevens Creek Boulevard

This former dry cleaning facility, located approximately 577 feet northwest of the Property, is listed in the CUPA LISTINGS, ECHO, EDR HIST CLEANER, FINDS, and RCRA -SQG databases searched by EDR. No information is available regarding chemicals handled at t his property or previous investigations; however, based on distance, this facility would not be expected to pose a concern to the Property.

Orphan Properties

One property is listed on the EDR “Orphan Summary” list but appear s to be located beyond the ASTM recommended radius search criteria.

Based on the distances to the identified database sites, regional topographic gradient, and the EDR findings, it is unlikely that releases from the above-stated database sites pose a current risk to the Property. Furthermore, soil gas conditions at the Property are well characterized and vapor intrusion will be mitigated through the installation of VIMS beneath future building foundations.

4.5 PER- AND POLYFLUOROALKYL SUBSTANCES

Per- and polyfluoroalkyl substances (PFAS) are a class of compounds used in a wide range of industrial processes and consumer products, including carpets, clothing, fabrics for furniture, packaging for food and cookware, and firefighting foam. PFAS are known as "forever chemicals" as the substances are highly recalcitrant in the environment. Common land uses associated with PFAS include sites where firefighting foam was used or stored; wastewater treatment plants utilizing biosolids spreading; chemical and electronics manufacturing facilities; landfills; and other industrial manufacturing facilities. In 2024, the USEPA announced i ts final rule designating two PFAS, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 40 CFR 302 (USEPA, 2024a) and publi shed the Final PFAS National Primary Drinking Water Regulation for six PFAS (USEPA, 2024b).

We reviewed the EDR Radius Map Report for PFAS database listings as well as the GeoTracker PFAS map (SWRCB, n.d.) for records of investigative orders, locations with PFAS data, or water system wells on the Property and within 1 mile of the Property. Neither the Property nor nearby Toll Brothers, Inc. Idlewild Shopping Center

sites were identified on PFAS database listings. Two water wells were mapped on the GeoTracker PFAS map within 1 mile (approximately 0.6 mile north-northwest of) the Property; neither of the wells reported detectable concentrations of PFAS compounds. Based on the historical use of the Property and nearby sites, we did not identify any on-site or off-site sources of PFAS that would be likely to impact soil or groundwater beneath the Property.

5.0 SITE RECONNAISSANCE

5.1 METHODOLOGY

We conducted a reconnaissance of the Property on June 3, 2025 . The reconnaissance was performed by Jenna Keith, a Project Engineer of ENGEO. We looked for hazardous materials storage, superficial staining or discoloration, debris, stressed vegetation, or other conditions that may be indicative of potential sources of soil or groundwater contamination. We also checked for evidence of fill/ventilation pipes, ground subsidence, or other evidence of existing or pre-existing USTs. Finally, we viewed adjoining pr operties from the Property and public thoroughfares to determine features, activities, uses, and conditions at adjoining properties that may indicate RECs at the Property. Photographs taken during the site reconnaissance are presented in Figures 4A through 4C.

We did not view the interior of any of the active or vacant commercial tenant spaces.

5.2 SITE AND ADJOINING PROPERTIES SETTING

5.5 ASBESTOS, LEAD, AND PCB-CONTAINING BUILDING MATERIALS

Common asbestos -containing building materials (ACBMs) include flooring and associated adhesive; baseboard and baseboard adhesive; carpet adhesive; leveling compound; drywall, joint and/or texturing compounds; ceiling tiles; roofing felts; roof patching com pounds; and mechanical/boiler system insulation. Federal regulations (40 CFR Part 61, Subpart M) require that potential ACBMs be sampled and analyzed for the presence of asbestos prior to any renovation or demolition activities that disturb such materials (USEPA, 2021b). Common lead - containing building materials include lead -based paint; roofing and pipework; and glazing and leaded glass. Common PCB-containing building materials include caulk, grout, and joint material; hydraulic fluid in elevators; fluores cent light ballasts; mastic used in tile and carpet; oil -based paints, sealants, coatings, varnishes, and lacquers; and asphaltic roofing. Hazardous building materials are generally found in buildings constructed prior to 1980.

An asbestos, lead, and PCB -containing building material survey is considered an ASTM non-scope item and was not conducted by ENGEO as part of this assessment. However, we were provided an Asbestos Inspection report prepared by Stockton Environmental Inc., dated October 25, 2023. The report identified both non -friable and friable ACBMs. The report recommended preparation of an asbestos abatement plan and engagement of a registered asbestos abatement contractor to remove ACBMs prior to demolition.

6.0 INTERVIEWS

We requested written and/or oral interviews with the User ; the present owners of the Property; and the SCCDEH case worker for the Former One-Hour Dry Cleaners case to obtain information regarding RECs in connection with the Property. The SCCDEH case worker declined our request for interview and referred us to GeoTracker. The questionnaires are presented in Appendix C.

6.1 USER INTERVIEW

Mr. Robert Connolly of Toll Brothers, Inc. completed a User -based environmental site questionnaire pertaining to applicable environmental information regarding the Property on May 12, 2025. In the questionnaire, Mr. Connolly identified the current Property owner as the Castello family . Mr . Connolly identified potential environmental issues with the Property as discussed in ENGEO’s 2023 phase I ESA. Mr. Connolly is unaware of commonly known, reasonably ascertainable, or specialized knowledge indicative of releases or threatened releases that is material to the potential presence of RECs. Mr. Connolly has indicated that the purchase price of the Property is reflective of fair market value of the Property.

6.2 KEY SITE MANAGER INTERVIEW

A Key Site Manager is defined as the current Property owner or owner representative, leasing agent, or other person having good knowledge of the uses and physical characteristics of the Property. Mr. Jeffrey Raines of Terraphase completed a Key Site Manager-related environmental site questionnaire on behalf of the Property owner on June 2, 2025. The questionnaire pertains to applicable environmental information regarding the Property and adjoining properties. In the questionnaire, Mr. Raines indicated that the Property was formerly used for agriculture; has been occupied by the current shopping center since 1960; and that the current Property owner, Idlewild TIC, assumed title of the Property in 2021. Mr. Raines indicated that the Property was formerly used for dry cleaning which released PCE into the subsurface.

Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 30 June 11, 2025

The questionnaire references the gasoline service station located at 19550 Stevens Creek Boulevard (APN 369 -06-007) as part of the Property. We note that this site is not part of the Property.

7.0 FINDINGS AND OPINIONS

This assessment included a review of local, state, tribal, and federal environmental record sources, standard historical sources, aerial photographs, fire insurance maps, and physical setting sources. We conducted a reconnaissance of the Property to review site use and current conditions to check for the storage, use, production, or disposal of hazardous or potentially hazardous materials and conducted written/oral interviews with persons knowledgeable about current and past site use.

7.1 FINDINGS

A review of regulatory databases maintained by county, state, tribal, and federal agencies found no documentation of hazardous materials violations or discharge on the Property and in general, did not identify contaminated facilities within the appropriate ASTM search distances that would reasonably be expected to impact the Property. However, the sit e reconnaissance and records review found documentation and physical evidence of soil and soil gas impairments associated with the past use of the Property.

Based on the findings of this assessment, one REC , no Historical RECs, and one (future) Controlled REC were identified for the Property.

• REC: Former One-Hour Cleaners PCE Releases
 Discharges of PCE from former dry cleaning operations have impacted the Property and off-site property to the west. PCE is present in soil gas and, to a lesser degree, soil, at concentrations exceeding residential and/or commercial ESLs 9,10. We understand that Idlewild TIC is responsible for site cleanup prior to transfer of the Property. We recommend continued remediation-related activities of the PCE plume at the Property as appropriate with regulatory oversight.

• Future Controlled REC: Institutional Controls/Deed Restriction  ICs will be required following successful completion of SVE. ICs will likely include an access agreement to allow SCCDEH personnel on Site at any time; funding for SCCDEH oversight; restriction of uses of the Property, restriction of modifications to the Property development without SCCDEH approval, and OM&M and rep orting for the VIMS that is expected to be installed under the planned residential units. A corresponding deed restriction would be recorded for the Property to ensure the systems remain operatio nal.

When approved, the ICs/deed restriction will represent a controlled REC for the Property.

Based on our review of regulatory databases and observations during the site reconnaissance, we identified the following BERs, PECs, and/or de minimis conditions. While not considered to be RECs, these features may pose an environmental concern to the Prop erty. We briefly discuss each feature below.

10 SFBRWQCB; Subslab/Soil Gas Vapor Intrusion: Human Health Risk Levels (Table SG -1); Commercial/Industrial; January 2019 (Rev. 1)
Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 31 June 11, 2025

• A hazardous building materials survey performed in 2023 identified asbestos -containing materials in the onsite commercial building. The cost of asbestos abatement and disposal is considered a BER.

7.2 DATA GAPS AND DATA FAILURES

As defined in the ASTM Standard Practice E1527-21, a data gap is:

A lack or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information.

A significant data gap is:

A data gap that affects the ability of the environmental professional to identify a recognized environmental condition.

The following data gaps were identified during this assessment.

• At the time of report publication, we had not received a response from the SCCFD.

The data gaps identified during this assessment do not affect our conclusions as to the presence of RECs at the Property.

As defined in the ASTM Standard Practice E1527-21, a data failure is:

Failure to achieve the historical research objective even after reviewing the standard historical resources that are reasonably ascertainable and likely to be useful. A data failure is one type of data gap.

Data failures are common when attempting to identify the use of the Property at 5-year intervals back to the first developed use or back to 1940, whichever is earlier. While gaps in the historical record information of greater than 5 years were identified, these data failures are not considered significant given the aggregate information available.

7.3 SIGNIFICANT DEVIATIONS FROM ASTM STANDARD PRACTICE

There were no significant deviations from ASTM Standard Practice E1527 -21 in the preparation of this report.

8.0 CONCLUSIONS

We have performed a phase I environmental site assessment of the Property in general conformance with the scope and limitations of ASTM E1527-21 and the standards and practices of the AAI Final Rule (40 CFR Part 312). Any exceptions to, or deletions from t his practice are described in Sections 7.0 and 9.0 of the report.

We believe that sufficient information has been obtained during our contracted scope of services to evaluate the presence of RECs at the Property. This assessment has revealed evidence of one REC, no Historical RECs, and one (future) Controlled REC, and no evidence of significant data gaps, in connection with the Property. We recommend the following.

Toll Brothers, Inc. Idlewild Shopping Center
22934.000.001 Phase I Environmental Site Assessment

Page | 32 June 11, 2025

• The remedial program should be continued under the oversight of SCCDEH. • SVE wells should be destroyed under SCCDEH oversight prior to Property redevelopment. • We recommend engaging a licensed asbestos abatement contractor to develop an asbestos abatement plan and remove asbestos-containing materials prior to building demolition.

9.0 LIMITATIONS

9.1 ASSUMPTIONS, LIMITATIONS, AND EXCEPTIONS OF ASSESSMENT

We strive to perform our professional services in accordance with generally accepted principles and practices currently employed in the area; there is no warranty, express or implied. The recommendations and conclusions presented in this report were based on the findings of our study, which were developed solely from the contracted services. The findings of the report are based in part on contracted database research, out -of-house reports, and personal communications. Our opinions formed are based on the assumed accuracy of the relied upon data in conjunction with our relevant professional experience related to such data int erpretation.

We assume no liability for the validity of the materials relied upon in the preparation of this report.

This document must not be subject to unauthorized reuse; that is, reuse without our written authorization. Such authorization is essential because it requires us to evaluate the document's applicability given new circumstances, not the least of which is passage of time. The findings from a phase I environmental site assessment are valid for one year after from the earliest date of the following components: records review, site reconnaissance, interviews, declaration by environmental professional. Updates of portions of the assessment may be necessary after a period of 180 days of the earliest date of the four components.

This phase I environmental site assessment is not intended to represent a complete soil, soil gas, or groundwater characterization, nor define the depth or extent of soil, soil gas, or groundwater contamination. It is intended to provide an evaluation of p otential environmental concerns associated with the use of the Property. Laboratory testing of soil, soil gas, or groundwater samples was not within the scope of the contracted services. The assessment did not include an asbestos survey, an evaluation of lead-based paint, an inspection of light ballasts for PCBs, or a mold survey. A radon evaluation was not performed.

This report is based upon field and other conditions discovered at the time of preparation of our assessment. Visual observations referenced in this report are intended only to represent conditions at the time of the reconnaissance. We would not be aware of site contamination, such as dumping and/or accidental spillage, which occurred subsequent to our site reconnaissance.

A more extensive assessment that would include a subsurface exploration with laboratory testing of soil, soil gas, and groundwater samples could provide more definitive information concerning site-specific conditions.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Lists of Federal NPL (Superfund) sites
NPL: Also known as Superfund, the National Priority List database is a subset of CERCLIS and identifies over 1,200 sites for priority cleanup under the Superfund program. The source of this database is the U.S. EPA.

A review of the NPL list, as provided by EDR, and dated 03/27/2025 has revealed that there is 1 NPL site within approximately 1 mile of the target property.

Lists of Federal CERCLA sites with NFRAP
SEMS-ARCHIVE: SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

A review of the SEMS-ARCHIVE list, as provided by EDR, and dated 03/27/2025 has revealed that there is 1 SEMS-ARCHIVE site within approximately 0.5 miles of the target property.

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list, as provided by EDR, and dated 01/21/2025 has revealed that there are 7 ENVIROSTOR sites within approximately 1 mile of the target property.
