of the project site along Gale Drive. This area is undeveloped but maintained and used for storage, as a standard-sized shipping container sits on the southwest side, likely for storage.
3. ANALYSIS METHODS
Prior to conducting the site survey and preparing this report, M&A researched the most recent version of CDFW’s Natural Diversity Database (CNDDB) (RareFind 5 application) for records of special-status plants and wildlife within three miles of the project site (CNDDB 2024). The CNDDB is a database maintained by the CDFW that provides historic and recent records of special-status plant and animal species known from the state of California. M&A also searched the current electronic version of the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Plants of California (CNPS 2001) for records of special-status plants known in the vicinity of the project site.
4. PLANT COMMUNITIES AND ASSOCIATED WILDLIFE HABITATS ONSITE As stated above, the project site is almost entirely developed except for an open area in the southern portion of the project site with a stand of trees that is maintained and used for storage purposes. The only plant community observed on the project site is landscaping, as further described below. Table 1 and Table 2 attached, provide the plant and wildlife species observed on the project site during M&A’s site visit.
4.1 Landscaping
A majority of the project site is developed. The trees in the undeveloped, maintained area in the southern portion of the project site were planted a long time ago. As such, there are no natural plant communities on the project site and almost all the plants observed are landscaping plants, with some non-native, weedy plants growing among the landscaping. The landscape trees on the project site within and around the parking lot include the Deodar cedar, coast live oak, coast redwood (Sequoia sempervirens), Chinese pistache (Pistacia chinensis), silk tree (Albiza julibrissin), fig (Ficus carica), weeping bottlebrush (Melaleuca viminalis), Japanese privet (Ligustrum japonicum), olive (Olea europa), Callery pear (Pyrus calleryana), tree of heaven (Ailanthus altissima) and Chinese elm (Ulmus parviflora).
The dominant shrubs on the project site include planted rosemary (Rosmarinus officinalis), ceanothus (Ceanothus sp.), pyracantha (Pyracantha sp.), cotoneaster (Cotoneaster sp.), juniper (Juniperus sp.) and heavenly bamboo (Nandina domestica). Weedy species growing among the landscaping plants include fennel (Foeniculum vulgare), Algerian ivy (Hedera canariensis), hairy fleabane (Erigeron bonariensis), willow lettuce (Lactuca saligna), common dandelion (Taraxacum officinale), burclover (Medicago minima) and oxalis (Oxalis sp.). Non-native grasses growing on the project site include red brome (Bromus rubens), barnyard grass (Echinochloa crus-gali), annual bluegrass (Poa annua) and smilo grass (Stipa miliacea var. miliacea).
The undeveloped area in the southern portion of the project site measuring approximately 70 feet wide contains predominantly Deodar cedar and coast live oak. Landscape plants such as olive, privet (Ligustrum sp.), Japanese pittosporum (Pittosporum tobira), have migrated to this area.

Campbell, California
Several young, coast redwood trees have been planted in this area and a few coyote brush (Baccharis pilularis subsp. pilularis) are scattered throughout. The understory vegetation is suppressed by a thick mat of fallen cedar needles, with annual bluegrass and red brome being a few species sparsely growing through the needle duff.
The developed project site provides habitat for animal species adapted to humans and humaninduced disturbances. The variety of flowering plants provides suitable foraging habitat for Anna’s Hummingbird (Calypte anna), and the landscape trees provide shelter and foraging for other species such as American Crow (Corvus brachyrhynchos), House Finch (Haemorhous mexicanus), Bushtit (Psaltriparus minimus), western gray squirrel (Sciurus griseus) and western fence lizard (Sceloporus occidentalis), all of which were observed on the project site. The open area to the south contains friable soil suitable for California ground squirrels (Otospermophilus beecheyi), which have created a small network of burrows. However, this undeveloped area is so small, surrounded by development, and supports such little vegetation that there is little suitable habitat for most wildlife species.
5. WATERS OF THE U.S. AND STATE
In the Federal Register "waters of the United States" are defined as, “...all interstate waters including interstate wetlands...intrastate lakes, rivers, streams (including intermittent streams), wetlands, [and] natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce...” (33 CFR Section 328.3).
Wetlands are defined as: “...those areas that are inundated or saturated by surface or ground water at a frequency and duration to support a prevalence of vegetation adapted for life in saturated soil conditions” (33 CFR Section 328.8 [b]). Wetlands usually must possess hydrophytic vegetation (i.e., plants adapted to inundated or saturated conditions), wetland hydrology (e.g., topographic low areas, exposed water tables, stream channels), and hydric soils (i.e., soils that are periodically or permanently saturated, inundated or flooded) to be regulated by the Corps pursuant to Section 404 of the Clean Water Act.
5.1 Applicability to the Proposed Project
There are no aquatic resources on the project site that would be regulated by the Corps pursuant to Section 404 of the Clean Water Act or the California Regional Water Quality Control Board pursuant to Section 401 of the Clean Water Act or the Porter-Cologne Water Quality Control Act. No seasonal wetlands or other waters were observed onsite. Attachment A provides the site plan created by Hunt, Hale and Jones dated August 14, 2024 and shows there are no proposed impacts to the adjacent channelized San Tomas Aquino Creek. Due to the lack of regulatory waters (or any aquatic resources) onsite, development of the property would not require any permits from state or federal agencies relating to waters of the State/U.S.

6. SPECIAL-STATUS SPECIES
Special-status species are those plants and animals that are legally protected under the California and Federal Endangered Species Acts (CESA and FESA, respectively) or other regulations, and species that are considered rare by the scientific community (for example, the CNPS). Specialstatus species also include plants and animals that meet the definition of endangered, rare, or threatened under the California Environmental Quality Act (CEQA) (14 CCR §15380) that may include species not found on either CESA or FESA lists.
The site is mostly developed, and the remaining undeveloped area is small and regularly maintained; there is no suitable habitat for special status plants or wildlife. Table 3 and Table 4 attached, list special status plant and wildlife species, respectively, known to occur within three miles of the project site and Figure 4 shows where these special-status species have been recorded in the area. The special-status plant species known to occur within three miles of the project site are typically found in natural habitats that are not present on the project site such as valley and foothill grassland, chaparral, cismontane woodland and alkaline meadows.
Similarly, the special-status wildlife species known to occur within three miles of the project site require grassland, woodlands, rivers, streams, wetlands and marshes, or large areas of open space, which do not occur on the project site. As such, most special-status species are not expected onsite. No impacts to special status plant species are expected due to the absence of habitat. The only special-status wildlife species expected onsite would be special-status bats and nesting birds. Both are discussed below.
6.1 Protections for Nesting Birds
6.1.1 FEDERAL MIGRATORY BIRD TREATY ACT
The Migratory Bird Treaty Act of 1918 (16 U.S.C. §§ 703-712, July 3, 1918, as amended 1936, 1960, 1968, 1969, 1974, 1978, 1986 and 1989) makes it unlawful to “take” (kill, harm, harass, shoot, etc.) any migratory bird listed in Title 50 of the Code of Federal Regulations, Section
10.13, including their active nests, eggs, or young. Migratory birds include geese, ducks, shorebirds, raptors, songbirds, wading birds, seabirds, and passerine birds (such as warblers, flycatchers, swallows, etc.).
6.1.2 CALIFORNIA FISH AND GAME CODE § 3503, 3503.5, 3511, AND 3513 California Fish and Game Code §§3503, 3503.5, 3511, and 3513 prohibit the “take, possession, or destruction of birds, their nests or eggs.” Disturbance that causes nest abandonment and/or loss of reproductive effort (killing or abandonment of eggs or young) is considered “take.” Such a take would also violate federal law protecting migratory birds (as discussed under the federal Migratory Bird Treaty Act above). The California Department of Fish and Wildlife (CDFW) has the responsibility of enforcing Fish and Game Code regulations.
Passerine birds (songbirds), waterfowl (ducks), and raptors (i.e., birds of prey), their active nests, eggs, and young are protected under California Fish and Game Code (§3503 and §3503.5) and the federal Migratory Bird Treaty Act (16 U.S.C. §§ 703-712).

6.2 Protections for Bats
Of the 25 species of bats in California, 13 are classified by the California Department of Fish and Wildlife (CDFW) as “species of special concern.” Species of special concern are protected pursuant to the CEQA, that is, they may meet the CEQA definition of “rare,” “threatened,” or “endangered,” (14 CCR §15380) and must be addressed in CEQA documents.
6.2.1 BAT ECOLOGY AND HABITAT REQUIREMENTS
Roost sites provide protection for bats as they sleep, rest in between foraging bouts, hibernate, mate (maternity roosts), socialize, and consume prey. Most of these activities occur at particular times – either day or night – and roosts are generally classified as either day or night roosts1.
Since bats are nocturnal, day roosts typically involve periods of rest and maternity sites, while night roosts are associated with temporary rest, prey processing and intraspecific communication interspersed with periods of foraging. Depending upon species, day roosts generally consist of crevices and cavities, with males often roosting separately from females. Breeding and maternity care may take place in day roosts in addition to resting.
In California, bats use a wide variety of roost sites, which can be divided into “natural roosts,” and man-made or “anthropogenic” roosts. Natural roost sites include caves, tree hollows, rock crevices, and exfoliating tree bark. Analogs to natural sites include buildings, mines, and bridges (Barbour and Davis, 19692, Constantine 19613, Davis and Cockrum 19634, Fenton 19835, Kunz 19826). Some species roost only in tree cavities or under bark, while others use a wider range of roost types – both natural and anthropogenic.
7. PROTECTED TREES
Chapter 21.32.070 of the City of Campbell Tree Protection Ordinance details the scope of protected trees and exceptions. The project site supports trees protected by the City ordinance as described as trees measuring twelve (12) inches or greater in diameter (thirty-eight inches or greater in circumference), measured four feet above the adjacent grade. As such, a tree removal permit would need to be applied for and acquired prior to any proposed impacts to trees on the project site.
An arborist report should be prepared to determine the species, size and number of protected trees that are located on the project site and proposed for removal, and a tree removal permit should be obtained prior to impacts to protected trees. Implementation of this mitigation measure would reduce impacts to protected trees to a level regarded as less than significant pursuant to CEQA.

8. RECOMMENDATIONS
M&A recommends the following measures to keep project impacts related to biological resources at a level considered less than significant pursuant to CEQA.
1. Nesting Bird Considerations. There are trees onsite that could provide suitable nesting habitat for songbirds and raptors. Thus, seven (7) days prior to any vegetation removal or ground disturbance/earthwork that would be conducted during the nesting season (February 1 through September 1) that could disturb nesting birds (for example, ground vibrations from grading equipment will cause some birds to abandon their nests), M&A recommends that preconstruction nesting bird surveys be conducted by a qualified biologist. If active bird nests are identified onsite during preconstruction surveys, then a non-disturbance buffer would need to be established around the nesting site(s) until the young have fledged. The size of the nondisturbance buffer would have to determined by a qualified biologist depending upon the nesting birds’ sensitivity to disturbance, but buffers are typically 75 feet for nesting passerine birds and up to 300 feet for nesting raptors. Implementation of this mitigation measure would reduce impacts to nesting birds to a level regarded as less than significant pursuant to CEQA.
2. Special-Status Bat Considerations. While there are no CNDDB records of special-status bats within three miles of the project site, the pallid bat (Antrozous pallidus) is known from within 5 miles of the project site and is designated as California “species of special concern.” This bat could roost in the trees or building onsite and common bat species including hoary bat (Lasiurus cinereus) could also be present on the project site.
As such, M&A recommends a qualified biologist conduct a survey for special-status and common bat species within the project site and a zone of influence around the project site prior to any building demolition, modification or any tree limbing or removal. This should include surveying all stands of trees and all tree hollows on the project site, examining any suitable openings for bats in trees or under loose bark for indirect evidence of bat use such as the presence of accumulations of invertebrate remains and/or the presence of excrement (guano) on the ground beneath such openings that would indicate roosting activity. If the building on site is proposed to be removed or renovated, all eaves and openings in the buildings should also be examined for evidence of bats.
If bats or signs of bats are found onsite, tree trimming and/or removal or building demolition should only be conducted during seasonal periods of bat activity: between August 31 and October 15, when bats would be able to fly and feed independently, and between March 1 and April 15 to avoid hibernating bats, and prior to the formation of maternity colonies.
Any trees that will be removed, and that the biologist has identified as having potentially suitable bat roost habitat, should be removed using a two-day phased removal method:
• On day one, in the afternoon, limbs and branches should be removed using chainsaws only. Limbs with cavities, crevices, and deep bark fissures should be avoided. • On day two, the rest of the tree should be removed under the direct supervision of the biologist.
Item 8.2

Due Diligence Biological Resources Site Assessment Report 700 West Hamilton Avenue Project
Campbell, California
If tree removal or building demolition must occur outside of the seasonal activity periods mentioned above (i.e., between October 16 and February 28/29, or between April 16 and April 30), then a qualified biologist, one with at least two years of experience surveying for bats, should do preconstruction surveys within 14 days of starting work. If the qualified biologist finds evidence of bat presence during the surveys, then they should develop a plan for removal and exclusion, in conjunction with CDFW. Implementation of this mitigation measure would reduce impacts to bats to a level regarded as less than significant pursuant to CEQA.
3. Protected trees. There are multiple large trees on the project site that may be considered protected by the City of Campbell and as such, a tree removal permit would need to be applied for and acquired prior to any proposed impacts to trees on the project site. An arborist report should be prepared to determine the species, size and number of protected trees that are located on the project site and proposed for removal, and a tree removal permit should be obtained prior to impacts to protected trees. Implementation of this mitigation measure would reduce impacts to protected trees to a level regarded as less than significant pursuant to CEQA.
9. CONCLUSIONS
The project site is located in an urban area and does not support sensitive or significant natural communities. Attachment A provides the site plan created by Hunt, Hale and Jones dated August 14, 2024 and shows there are no proposed impacts to the adjacent, offsite San Tomas Aquino Creek. Due to the lack of regulatory waters (or any aquatic resources) onsite, development of the property would not require any permits from state or federal agencies relating to waters of the State/U.S. Further, M&A did not find any natural habitats onsite that could support sensitive, or special-status plant species. Nesting birds and special-status bats are the two considerations on the project site pertaining to biological resources. Any proposed project on this project site would need to undergo a CEQA review with the City of Campbell, with any potential impacts to special-status bats and nesting birds mitigated to a less than significant level. The mitigation measures recommended above would be sufficient for reducing project impacts to special-status bats and nesting birds to a level considered less than significant.
There are no other constraints pertaining to biological resources that would impact the proposed development. Should you have any questions or wish to discuss any other aspect of this report, please do not hesitate to contact me at (925) 947-4867 extension 208 or email at [email protected].

Introduction
The purpose of this report is to determine whether the proposed residential project located at 700 W. Hamilton Avenue in Campbell, California would have any potential air quality, health risk, and greenhouse gas (GHG) impacts. The project is consistent with the development density established by the general plan, for which an EIR was certified. CEQA Guideline section 15183 states that such a project “shall not require additional environmental review, except as might be necessary to examine whether these are project-specific significant effects which are specific to the project or its site.” (14 Cal. Code Regs. § 15183(a)).
Air quality impacts and GHG emissions would be associated with the demolition of the existing buildings at the site and the construction and operation of the new residential buildings and infrastructure. Air pollutant emissions associated with construction of the project were estimated using appropriate computer models. In addition, the potential project health risks, and impacts of existing toxic air contaminant (TAC) sources affecting the existing and new sensitive receptors in the area were evaluated. The analysis was conducted following guidance provided by the Bay Area Air Quality Management District (BAAQMD).1
Project Description
The 3.83-acre project site is currently developed with an office building and associated surface parking lot. The project proposes to demolish these and construct 173 townhome units totaling 212,848 square feet (sf) of residential use. Each townhouse would include a one- or two-car tandem parking garage. The project would also include 30 guest parking spaces. Construction is proposed from October 2026 through May 2028.
The Project would include the following Conditions of Approval (COA) as a design feature of the Project in order for the Project to have less-than-significant air quality impacts.
Condition of Approval AQ-1: Use construction equipment that has low diesel particulate matter exhaust emissions.
Implement a feasible plan to reduce diesel particulate matter emissions by at least 60 percent such that increased cancer risk from construction would be reduced below TAC significance levels as follows:
1. All construction equipment larger than 25 horsepower used at the site for more than two continuous days or 20 hours total shall meet U.S. EPA Tier 4 final emission standards, if feasible, otherwise,
Alternatively, the applicant may develop another construction operations plan demonstrating that the construction equipment used on-site would achieve a reduction in construction diesel particulate matter emissions by at least 60 percent or greater. Elements of the plan could include a combination of some of the following measures:
1 Bay Area Air Quality Management District, 2022 CEQA Guidelines, April 2023.
Item 8.2
Tuesday, January 20, 2026 455 of 681
• Installation of electric power lines during early construction phases to avoid use of diesel portable equipment,
• Use of electrically powered equipment,
• Forklifts and aerial lifts used for exterior and interior building construction shall be electric or propane/natural gas powered,
• Change in construction build-out plans to lengthen phases, and • Implementation of different building techniques that result in less diesel equipment usage.
Such a construction operations plan would be subject to review by an air quality expert and approved by the City prior to construction.
Setting
The project is located in Santa Clara County, which is in the San Francisco Bay Area Air Basin.
Ambient air quality standards have been established at both the State and federal level. The Bay Area meets all ambient air quality standards with the exception of ground-level ozone, respirable particulate matter (PM10), and fine particulate matter (PM2.5).
Air Pollutants of Concern
High ozone concentrations in the air basin are caused by the cumulative emissions of reactive organic gases (ROG) and nitrogen oxides (NOX). These precursor pollutants react under certain meteorological conditions to form ozone concentrations. Controlling the emissions of these precursor pollutants is the focus of the Bay Area’s attempts to reduce ambient ozone concentrations. The highest ozone concentrations in the Bay Area occur in the eastern and southern inland valleys that are downwind of air pollutant sources. High ozone concentrations aggravate respiratory and cardiovascular diseases, reduce lung function, and increase coughing and chest discomfort.
Particulate matter is another problematic air pollutant in the air basin. Particulate matter is assessed and measured in terms of respirable particulate matter or particles that have a diameter of 10 micrometers or less (PM10) and fine particulate matter where particles have a diameter of 2.5 micrometers or less (PM2.5). Elevated concentrations of PM10 and PM2.5 are the result of both region-wide (or cumulative) emissions and localized emissions. High particulate matter concentrations aggravate respiratory and cardiovascular diseases, reduce lung function, increase mortality (e.g., lung cancer), and result in reduced lung development in children. Due to the adverse health effects caused by PM2.5 exposure even at low concentrations, BAAQMD has developed health risk thresholds to address exposure to increased PM2.5 concentrations.2 Toxic Air Contaminants
TACs are a broad class of compounds known to cause morbidity or mortality, often because they cause cancer. TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically 2 BAAQMD, 2022 CEQA Air Quality Guidelines, Appendix A, p40.
Item 8.2
Tuesday, January 20, 2026 456 of 681
found in low concentrations, even near their source (e.g., diesel particulate matter [DPM] near a freeway). Because chronic exposure of TACs can result in adverse health effects, they are regulated at the regional, State, and federal level.
Diesel exhaust is the predominant TAC in urban air and is estimated to represent about seventy percent of the cancer risk from TACs (based on the Bay Area average).3 According to the California Air Resources Board (CARB), diesel exhaust is a complex mixture of gases, vapors, and fine particles. This complexity makes the evaluation of health effects from diesel exhaust exposure a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified as TACs by the CARB, and are listed as carcinogens either under the State's Proposition 65 or under the Federal Hazardous Air Pollutants programs. Health risks from TACs are estimated using the Office of Environmental Health Hazard Assessment (OEHHA) risk assessment guidelines, which were published in February of 2015 and incorporated in BAAQMD’s current California Environmental Quality Act (CEQA) guidance.4 Sensitive Receptors
There are groups of people more affected by air pollution than others. CARB has identified the following persons who are most likely to be affected by air pollution: children under 16, the elderly over 65, athletes, and people with cardiovascular and chronic respiratory diseases. These groups are classified as sensitive receptors. Locations that may contain a high concentration of these sensitive population groups include residential areas, hospitals, daycare facilities, elder care facilities, and elementary schools. While not considered sensitive receptors, health risk impacts to nearby workers are also included in CEQA analysis to ensure their impacts do not exceed those of nearby sensitive receptors.
For cancer risk assessments, infants and small children are the most sensitive receptors, since they are more susceptible to cancer causing TACs. Residential locations are assumed to include infants and small children. The closest sensitive receptors would be the families located in the nearby single-family and multi-family residences and the children attending the Little Tree Montessori Internation School adjacent to the west of the site. There are also single-family homes on the opposite side of Gale Drive to the south and single- and multi-family residences located to the north and east of the site. Additionally, children attend the Hearts and Hands Christian Childcare & Preschool located to the east of the project site. This project would introduce new sensitive receptors (i.e., residents) to the area.
Bay Area Air Quality Management District (BAAQMD)
BAAQMD has jurisdiction over an approximately 5,600-square mile area, commonly referred to as the San Francisco Bay Area (Bay Area). The District’s boundary encompasses the nine San Francisco Bay Area counties, including Alameda County, Contra Costa County, Marin County, 3 CARB, Summary: Diesel Particulate Matter Health Impacts, Web: https://ww2.arb.ca.gov/resources/summarydiesel-particulate-matter-health-impacts#footnote1_7yob8j5. 4 OEHHA, 2015.

San Francisco County, San Mateo County, Santa Clara County, Napa County, southwestern Solano County, and southern Sonoma County.
BAAQMD is the lead agency in developing plans to address attainment and maintenance of the National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS). The District also has permit authority over most types of stationary equipment. The BAAQMD is responsible for permitting and inspection of stationary sources; enforcement of regulations, including setting fees, levying fines, and enforcement actions; and ensuring that public nuisances, such as fugitive dust from construction sites, are minimized.
BAAQMD’s Community Air Risk Evaluation (CARE) program was initiated in 2004 to evaluate and reduce health risks associated with exposures to outdoor TACs in the Bay Area.5 The program
examines TAC emissions from point sources, area sources, and on-road and off-road mobile sources with an emphasis on diesel exhaust, which is a major contributor to airborne health risk in California. The CARE program is an on-going program that encourages community involvement and input. The technical analysis portion of the CARE program has been implemented in three phases that includes an assessment of the sources of TAC emissions, modeling and measurement programs to estimate concentrations of TAC, and an assessment of exposures and health risks.
Throughout the program, information derived from the technical analyses has been used to develop emission reduction activities in areas with high TAC exposures and high density of sensitive populations. Risk reduction activities associated with the CARE program are focused on the most at-risk communities in the Bay Area. Seven areas have been identified by BAAQMD as impacted communities. They include Eastern San Francisco, Richmond/San Pablo, Western Alameda, San José, Vallejo, Concord, and Pittsburgh/Antioch. The project site is located within the San José CARE area.
Overburdened communities are areas located (i) within a census tract identified by the California Communities Environmental Health Screening Tool (CalEnviroScreen), Version 4.0 implemented by OEHHA, as having an overall score at or above the 70th percentile, or (ii) within 1,000 feet of any such census tract.6 The BAAQMD has identified several overburdened areas within its boundaries. However, the project site is not within an overburdened area as the Project site is scored at the 12th percentile on CalEnviroScreen.7
BAAQMD CEQA Air Quality Guidelines
In June 2010, BAAQMD adopted thresholds of significance to assist in the review of projects under CEQA. In 2023, the BAAQMD revised their California Environmental Quality Act (CEQA) Air Quality Guidelines that include significance thresholds to assist in the evaluation of air quality impacts of projects and plans proposed within the Bay Area. The current BAAQMD guidelines provide recommended procedures for evaluating potential air impacts during the environmental review process consistent with CEQA requirements. Included in the guidelines are assessment 5 See BAAQMD: https://www.baaqmd.gov/community-health/community-health-protection-program/communityair-risk-evaluation-care-program. 6 See BAAQMD: https://www.baaqmd.gov/~/media/dotgov/files/rules/reg-2-permits/2021- amendments/documents/20210722_01_appendixd_mapsofoverburdenedcommunities-pdf.pdf?la=en. 7 OEHAA, CalEnviroScreen 4.0 Maps https://oehha.ca.gov/calenviroscreen/report/calenviroscreen-40 Item 8.2

methodologies for criteria air pollutants, air toxics, odors, and GHG emissions. Table 1 provides the current CEQA significance thresholds developed by BAAQMD.8 Air quality impacts and
health risks are considered potentially significant if they exceed these thresholds.
The BAAQMD recommends all projects include a “basic” set of best management practices (BMPs) to manage fugitive dust and consider impacts from dust (i.e., fugitive PM10 and PM2.5) to be less than significant if BMPs are implemented (listed below). BAAQMD strongly encourages enhanced BMPs for construction sites near schools, residential areas, other sensitive land uses, or if the basic BMPs do not adequately reduce fugitive emissions below BAAQMD significance thresholds.

Construction Period Emissions
The California Emissions Estimator Model (CalEEMod) Version 2022 was used to estimate emissions from the project’s construction activities and construction-related vehicle trips. The project’s land use types and sizes were input to CalEEMod. The CalEEMod model output along with the construction information used are included in Attachment 1.
CalEEMod Inputs
Land Uses
The proposed project land uses were entered into CalEEMod as described in Table 2.

Enclosed Parking Structure 268 Parking Space 59,662 3.83 Parking Lot 30 Parking Space -
*Includes residential and deck square footage
Construction Inputs
CalEEMod computes annual emissions for construction based on land use type, size, and site acreage. The model estimates emissions for both on-site and off-site construction activities. Onsite activities are primarily made up of construction equipment emissions, while off-site activity includes worker, hauling, and vendor traffic. The construction scenario, including equipment quantities, average hours of equipment use per day, and total number of workdays were based on CalEEMod default information for a project of this type and size (included in Attachment 1). The project applicant estimates the earliest possible start date to be October 2026, and the project would Item 8.2
Tuesday, January 20, 2026 463 of 681
be built out over a period of approximately 20 months, or 430 construction workdays. The operational year (i.e., construction complete) was assumed to be 2029.
Construction Traffic Emissions
Construction would produce traffic in the form of worker trips and truck traffic. Traffic-related emissions are based on worker and vendor trip estimates produced by CalEEMod and haul trips based on the estimated amount of demolition material to be exported, the estimated amount of soil imported and/or exported to the site, and the estimated amount of concrete and asphalt deliveries to and from the site. CalEEMod provides daily estimates of worker and vendor trips for each phase of construction, while daily haul trips for demolition and soil import/export activities are estimated by CalEEMod based on information input into the model. The amount of concrete/asphalt needed for the project was estimated and converted to daily one-way trips, assuming two trips per delivery.
Estimated Construction Period Emissions and Required Control Measures Average daily emissions were annualized for each year of construction by dividing the annual construction emissions by the number of active workdays during that year. Table 3 shows the annualized average daily construction emissions of ROG, NOX, PM10 exhaust, and PM2.5 exhaust during construction of the project. As indicated in Table 3, predicted annualized project construction emissions would not exceed the BAAQMD significance thresholds during any year of construction.

Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust (i.e., fugitive sources of PM10 and PM2.5). Sources of fugitive PM10 and PM2.5 include disturbed soils at the construction site and trucks carrying uncovered loads of soils.
Unless properly controlled, vehicles leaving the site deposit mud on local streets, which is an additional source of PM10 and PM2.5 after it dries. The BAAQMD recommends all projects include a “basic” set of BMPs to manage fugitive dust and considers impacts from fugitive PM10 and PM2.5 to be less-than-significant when they are implemented. The City’s General Plan Policy COS-10.4 requires implementation of BAAQMD’s basic BMPs to control fugitive sources of PM10 and PM2.5 during construction. Therefore, the construction contractor(s) are required to implement the following BMPs to control fugitive sources of PM10 and PM2.5 :
Item 8.2
Tuesday, January 20, 2026 464 of 681
1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day.
2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
3. All visible mud or dirt track-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.
4. All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).
5. 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.
6. All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph.
7. All trucks and equipment, including their tires, shall be washed off prior to leaving the site.
8. Unpaved roads providing access to sites located 100 feet or further from a paved road shall be treated with a 6- to 12-inch layer of compacted layer of wood chips, mulch, or gravel.
9. Publicly visible signs shall be posted with the telephone number and name of the person to contact at the lead agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s General Air Pollution Complaints number shall also be visible to ensure compliance with applicable regulations.
Construction Health Risk Impacts
Health risk impacts were addressed by predicting increased lifetime cancer risk, the increase in annual PM2.5 concentrations, and computing the Hazard Index (HI) for non-cancer health risks.
Construction activity is the only source of TAC emissions from the Project. Construction equipment and associated heavy-duty truck traffic generates diesel exhaust and PM2.5. Diesel exhaust is a known carcinogen and poses health risks for sensitive receptors. A health risk assessment of the Project’s construction activities was conducted that evaluated potential health effects to nearby sensitive receptors from construction emissions of diesel exhaust (as DPM) and PM2.5.
10 This assessment used dispersion modeling to predict the off-site concentrations of DPM and PM2.5 (including fugitive sources) resulting from project construction, so that health risks could be evaluated.
10 DPM is identified by California as a toxic air contaminant due to the potential to cause cancer.

Modeled Sensitive Receptors
Receptors for this assessment included locations where sensitive populations would be present for extended periods of time (i.e., chronic exposures). This includes the existing residences near the site as shown in Figure 1. Residential receptors are assumed to include all receptor groups (i.e., third trimester, infants, children, and adults) with almost continuous exposure to project emissions.
Health risks were also computed for child receptors at the nearby preschools. PM2.5 concentrations were also calculated at worker receptors near the project site. While there are additional sensitive receptors within 1,000 feet of the project site, the receptors chosen are adequate to identify maximum impacts from the project.
Construction TAC Emissions
The CalEEMod model estimated the total annual PM10 exhaust emissions (assumed to be 100 percent DPM) for the off-road construction equipment and for exhaust emissions from on-road vehicles to be 0.08 tons (157 pounds). The on-road emissions are a result of haul truck travel during grading activities, worker travel, and vendor deliveries during construction. A trip length of halfa-mile was used to represent vehicle travel while at or near the construction site. It was assumed that the emissions from on-road vehicles traveling at or near the site would occur at the construction site. Total PM2.5 from fugitive dust emissions was estimated to be 0.03 tons (51 pounds) and are solely from material-moving activities.
Dispersion Modeling
The U.S. EPA AERMOD dispersion model was used to predict DPM and PM2.5 concentrations at receptors (both sensitive and non-sensitive) in the vicinity of the project construction area. The AERMOD dispersion model is a BAAQMD-recommended model for use in modeling analysis of these types of emission activities for CEQA projects.11 Emission sources for the construction site were grouped into two categories: exhaust emissions of DPM and fugitive PM2.5 dust emissions.
Construction Sources
To represent the construction equipment exhaust emissions, an area source was used with an emission release height of 20 feet (6 meters).12 The release height incorporates both the physical release height from the construction equipment (i.e., the height of the exhaust pipe) and plume rise after it leaves the exhaust pipe. Plume rise is due to both the high temperature of the exhaust and the high velocity of the exhaust gas. It should be noted that when modeling an area source, plume rise is not calculated by the AERMOD dispersion model as it would do for a point source (exhaust stack). Therefore, the release height from an area source used to represent emissions from sources with plume rise, such as construction equipment, was based on the height the exhaust plume is expected to achieve, not just the height of the top of the exhaust pipe. DPM emissions from the construction equipment and on-road vehicle travel were distributed throughout the modeled area sources.

Tuesday, January 20, 2026 466 of 681
For modeling fugitive PM2.5 emissions, an area source with a near-ground level release height of 7 feet (2 meters) was used. Fugitive dust emissions at construction sites come from a variety of sources, including truck and equipment travel, grading activities, truck loading (with loaders) and unloading (rear or bottom dumping), loaders and excavators moving and transferring soil and other materials, etc. All of these activities result in emissions at various heights at the point(s) of generation. Once generated, the dust plume will tend to rise as it moves downwind across the site and exits the site at a higher elevation than when it was generated. For all these reasons, a 7-foot release height was used as the average release height across the construction site.
AERMOD Inputs and Meteorological Data
The modeling used a five-year data set (2013 - 2017) of hourly meteorological data from the San José Airport prepared for use with the AERMOD model by BAAQMD. Construction emissions were modeled as occurring Monday through Friday between 9:00 a.m. to 5:00 p.m., the times when construction activities would occur according to the applicant. Annual DPM and fugitive PM2.5 concentrations from construction activities during the 2026-2028 period were calculated at nearby receptors using the model. Receptor heights of 5 feet (1.5 meters) and 15 feet (4.5 meters) were used to represent the breathing height on the first and second floors of nearby single- and multifamily residences and workers at the nearby businesses.13 A receptor height of 3 feet (1 meter) was used to represent the breathing heights of children at the daycares and preschools.
Summary of Construction Health Risk Impacts
The maximum increased cancer risks were calculated using the modeled DPM concentrations and the age sensitivity factors, and exposure parameters recommended by BAAQMD CEQA guidance.
Age-sensitivity factors reflect the greater sensitivity of infants and small children to cancer causing TACs. Third trimester, infant, child, and adult exposures were assumed to occur at all residences during the entire construction period, while child exposures were assumed at the preschool. Offsite worker exposures were based on adult breathing parameters assuming an 8-hour shift.
Non-cancer health hazards and maximum PM2.5 concentrations were also calculated. The maximum modeled annual PM2.5 concentration was calculated based on combined DPM and fugitive PM2.5 concentrations. The maximum computed HI value was based on the ratio of the maximum DPM concentration modeled and the chronic inhalation DPM reference exposure level of 5 µg/m3 .
Maximum annual DPM and PM2.5 concentrations were used to identify the MEI, which was located at a single-family residence south of the project site opposite Gale Drive. The location of the MEI and nearby receptors are shown in Figure 1. Table 4 summarizes the maximum cancer risks, PM2.5 concentrations, and HI for project construction activities. Attachment 2 to includes the emission calculations used for the dispersion modeling and the cancer risk calculations.

Cumulative Health Risks of all TAC Sources at the Off-Site MEI Cumulative health risk assessments look at all substantial sources of TACs located within 1,000 feet of a project site (i.e., influence area) that can affect sensitive receptors. These sources include rail lines, highways, busy surface streets, and stationary sources identified by BAAQMD.
A review of the project area using BAAQMD’s geographic information systems (GIS) screening maps identified the existing health risks from nearby TAC sources at the MEI. Two nearby roadways (W. Hamilton Avenue and San Tomas Expressway) and four stationary sources within the 1,000-foot influence area were identified with the potential have cumulative health risk impacts at the MEI. Figure 2 shows the locations of the sources affecting the MEI within the influence area. Health risk impacts from these sources upon the MEI are reported in Table 5. Details of the cumulative screening, modeling, and health risk calculations are included in Attachment 3.
Figure 2. Project Site and Nearby TAC and PM2.5 Sources Nearby High-Volume Roadways – W. Hamilton Avenue and San Tomas Expressway A refined analysis of potential health impacts from vehicle traffic on W. Hamilton Avenue and San Tomas Expressway was conducted. The refined analysis involved predicting emissions for the Item 8.2

traffic volume and mix of vehicle types on the roadways near the project site and using an atmospheric dispersion model to predict exposure to traffic-related TACs. The associated cancer risks are then computed based on pollutant concentrations.
Traffic Emissions Modeling
This analysis involved the development of DPM, organic TACs, and PM2.5 emissions for traffic on W. Hamilton Avenue and San Tomas Expressway using the Caltrans version of the CARB EMFAC2021 emissions model, known as CT-EMFAC2021. CT-EMFAC2021 provides emission factors for mobile source criteria pollutants and TACs, including DPM. Emissions were estimated for running exhaust for DPM, PM2.5 and total organic compounds (TOG), running evaporative losses for TOG, and fugitive emissions of PM2.5 that include tire wear, brake wear, and road dust.
Inputs to the model include region (Santa Clara County), type of road (major/collector), traffic mix assigned by CT-EMFAC2021 for the county, year of analysis (2026 construction start year), and season (annual).
Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the emissions model, the higher the emission rates. Year 2026 emissions conservatively represent future conditions over the time period that cancer risks are evaluated (i.e., 30-years) since vehicle exhaust and evaporative emissions will decrease in the future.
The average daily traffic (ADT) for W. Hamilton Avenue and San Tomas Expressway was based on information in the Transportation Section of the Draft Environmental Impact Report (DEIR) for the City’s General Plan.14 Traffic counts take in 2016 indicate volumes on W. Hamilton Avenue were in excess of 30,500 vehicles per day and in excess of 45,400 vehicles per day on San Tomas Expressway. These counts were grown to 2026 levels assuming a one percent increase in traffic volume per year based on the built-out nature of the area. Thus, 2026 traffic volume estimates used for the analysis were 33,550 vehicles per day for W. Hamilton Avenue and 49,940 vehicles per day on San Tomas Expressway.
Hourly traffic distributions for the roadways were estimated by averaging hourly traffic volumes from nearby State Route (SR) 17 using Caltrans Performance Measurement System (PeMS) data.
PeMS data is collected in real-time from nearly 40,000 individual detectors spanning the freeway system across all major metropolitan areas of California.15 The average fraction of traffic volume each hour was calculated using PeMS data and applied to the traffic estimates for the roadways to obtain hourly traffic emission rates.
An average speed of 35 mph on W. Hamilton Avenue and 45 mph on San Tomas Expressway was assumed during off-peak periods. Speeds during the peak periods were assumed to be 5 miles per hour slower (i.e., 30 mph and 40 mph) to account for peak period congestion and congestion near the intersection of W. Hamilton Avenue at San Tomas Expressway. 14 Section 3.14, Page 3.14-6.

Hourly emissions rates were developed for DPM, organic TACs, and PM2.5 along the applicable segments of W. Hamilton Avenue and San Tomas Expressway within 1,000 feet of the project site. AERMOD was used to estimate the pollutant concentrations at the MEI location. Maximum increased lifetime cancer risks at the MEI receptor were then computed using modeled DPM and TOG concentrations and BAAQMD methods and exposure parameters.
Dispersion Modeling
Dispersion modeling was conducted using the EPA AERMOD air quality dispersion model, which is recommended by the BAAQMD for this type of analysis.16 Pollutant emissions from traffic on W. Hamilton Avenue and San Tomas Expressway within 1,000 feet of the project site were evaluated as a series of area sources along a line (line area sources); with line segments used to represent both directions of travel. The same meteorological data and off-site receptors used in the previous construction site dispersion modeling scenario were used in the roadway modeling. Other inputs to the model included road geometry and hourly traffic emissions. Annual pollutant concentrations were calculated at the MEI with receptor heights of 5 feet (1.5 meters), which were used to represent the breathing heights on the first floor of the single-family home.
Computed Cancer and Non-Cancer Health Impacts
The cancer risk, maximum annual PM2.5 concentration, and DPM-based HI impacts from each roadway on the off-site MEI are shown in Table 5. Figure 2 shows the roadway links modeled and receptor locations where concentrations were calculated. Details of the emission calculations, dispersion modeling, and cancer risk calculations for the MEI are provided in Attachment 3.
BAAQMD Permitted Stationary Sources
Permitted stationary sources of air pollution near the project site were identified using BAAQMD’s Permitted Stationary Sources 2022 GIS website,17 which identifies the location of nearby stationary sources and their estimated risk and hazard impacts, including emissions and adjustments based on OEHHA guidance. Four sources were identified using this tool, two emergency diesel generators and two gasoline dispensing facilities (GDF). A stationary source information request was submitted to BAAQMD in order to estimate health risk impacts from the GDF.18
The screening risk and hazard levels provided by BAAQMD for the stationary sources were adjusted for distance using BAAQMD’s Distance Adjustment Multiplier Tool for Diesel Internal Combustion Engines and CARBS’s Gasoline Station Risk Screening Tool. BAAQMD provided the gasoline throughput for the gas dispensing facilities near the project site.

Non-CEQA: On-site Health Risk Assessment of TAC Sources – New Sensitive Receptors
A health risk assessment was completed to assess the impact that nearby existing TAC sources would have on the proposed new sensitive receptors (residents) that the project would introduce.
The same TAC sources identified in Table 5 were used in this assessment.19 BAAQMD’s CEQA significance thresholds for health risks and hazards, shown in Table 1, are used to evaluate on-site exposure. Maximum on-site single source and cumulative health risks are listed in Table 6.
Attachment 3 includes the emissions modeling and risk calculations for TAC source impacts upon the on-site MEI.
Nearby High-Volume Roadways – W. Hamilton Avenue and San Tomas Expressway The high-volume roadway impacts on project residents were estimated in the same manner as described above for the off-site MEI. However, emission factors for the year 2029 (operational year) were conservatively assumed as being representative of on-site conditions. Traffic volumes on W. Hamilton Avenue and San Tomas Expressway were grown to 2029 conditions by assuming a one percent increase in traffic volume per year. Thus, daily traffic volumes on W. Hamilton Avenue were estimated to be 34,465 and 51,302 on San Tomas Expressway.
Receptors were placed at the location of proposed dwelling units based on the site plan provided by the applicant. Roadway impacts were modeled at receptor heights of 18.4 feet (5.6 meters) and 26 feet (7.9 meters) representing sensitive receptors on the second and third floors of the proposed dwellings. The first floor of each unit would be a garage, and not considered a dwelling space. The portions of each roadway included in the modeling are shown in Figure 3 along with the project site and receptor locations where concentrations were calculated.
Maximum increased cancer risks were calculated for the MEI at the project site using the maximum modeled pollutant concentrations. A 30-year exposure period was used in calculating cancer risks assuming a resident would grow from infant to adulthood at the location with an exposure of 24 hours per day for 350 days per year. The maximum impacts from both roadways occurred at a receptor near the northwest corner of the project site, adjacent to W. Hamilton Avenue. Pollutant concentrations are greatest closest to the roadways and decrease with distance from the roads. Roadway health risk impacts at the on-site MEI are shown in Table 6. Details of the emission calculations, dispersion modeling, and cancer risk calculations are contained in Attachment 3.

Stationary Sources
The stationary source screening analysis of the source for the new project sensitive receptors was conducted in the same manner as described above for the cumulative analysis. Table 6 includes the health risk screening results for the stationary source at the project site.
Summary of Cumulative Health Risks at the Project Site
Health risk impacts from the existing TAC sources upon the project site are reported in Table 6.
Risks from each source are compared against the BAAQMD single-source thresholds, while the combined risks from all the sources are compared against the BAAQMD cumulative-source thresholds. PM2.5 concentrations at the MEI from W. Hamilton Avenue exceed the BAAQMD single-source threshold of 0.3 µg/m3. However, no other single source exceeds the BAAQMD CEQA single source thresholds. Likewise, the cumulative health risks from all the sources would not exceed any of the BAAQMD cumulative source CEQA thresholds. Because the maximum annual PM2.5 concentration at the MEI exceeds the BAAQMD single source threshold, design features to reduce PM2.5 exposure to residents of the Project are recommended.

Recommended Design Features to Reduce Project PM2.5 Exposure Ventilation system filtration for each residential unit is recommended to reduce the level of PM2.5 concentrations attributable to W. Hamilton Avenue to below the BAAQMD single-source threshold of 0.3 µg/m3
. PM2.5 concentrations are high due primarily to fugitive sources of PM2.5, including the brake wear, tires wear, and re-entrainment of roadway dust from vehicles traveling over pavement. Reducing particulate matter exposure would reduce both annual PM2.5 exposures and cancer risk, although cancer risks at the MEI are below the BAAQMD thresholds.
In order to meet BAAQMD CEQA significance thresholds, the project needs to include the following measures to minimize annual PM2.5 exposure for on-site occupants:
1. Install air filtration for each residential unit. Air filtration devices shall be rated MERV13 or higher. To ensure adequate health protection to sensitive receptors (i.e., residents), this ventilation system, whether mechanical or passive, shall filter all fresh air that would be circulated into the dwelling units.
Item 8.2
Tuesday, January 20, 2026 475 of 681
2. The ventilation system shall be designed to keep the building at positive pressure when doors and windows are closed to reduce unfiltered outside air from entering the building
3. As part of implementing this measure, an ongoing maintenance plan for the buildings’ heating, ventilation, and air conditioning (HVAC) air filtration system shall be required that includes regular filter replacement.
4. Ensure that the use agreement and other property documents: (1) require cleaning, maintenance, and monitoring of the affected buildings for air flow leaks, (2) include assurance that new owners or tenants are provided information on the ventilation system, and (3) include provisions that fees associated with owning or leasing a unit(s) in the building include funds for cleaning, maintenance, monitoring, and replacements of the filters, as needed.
Effectiveness of Recommended Design Features
A professionally installed and operated ventilation system with MERV13 would achieve a 90- percent reduction for small particulates.20 The overall effectiveness calculations consider the amount of time spent outdoors at the project site but not time spent away from home. Assuming that the filtration system is 80-percent effective, and the individual is being exposed to 21 hours of indoor filtered air and three hours of outdoor unfiltered air at the site, the overall effectiveness of a MERV13 filtration system would be about 70-percent for PM2.5 exposure. This would reduce the maximum annual PM2.5 concentrations to 0.10 µg/m3

Greenhouse Gas Emissions
Setting
Gases that trap heat in the atmosphere, GHGs, regulate the earth’s temperature. This phenomenon, known as the greenhouse effect, is responsible for maintaining a habitable climate. The most common GHGs are carbon dioxide (CO2) and water vapor but there are also several others, most importantly methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These are released into the earth’s atmosphere through a variety of natural processes and human activities. Sources of GHGs are generally as follows:
CO2, CH4, and N2O are byproducts of fossil fuel combustion. N2O is associated with agricultural operations such as fertilization of crops. CH4 is commonly created by off-gassing from agricultural practices (e.g., keeping livestock) and landfill operations.
Chlorofluorocarbons (CFCs) were widely used as refrigerants, propellants, and cleaning solvents but their production has been stopped by international treaty. HFCs are now used as a substitute for CFCs in refrigeration and cooling. PFCs and sulfur hexafluoride emissions are commonly created by industries such as aluminum production and semi-conductor manufacturing.
Each GHG has its own potency and effect upon the earth’s energy balance. This is expressed in terms of a global warming potential (GWP), with CO2 being assigned a value of 1 and sulfur hexafluoride being several orders of magnitude stronger. In GHG emission inventories, the weight of each gas is multiplied by its GWP and is measured in units of CO2 equivalents (CO2e).
An expanding body of scientific research supports the theory that global climate change is currently affecting changes in weather patterns, average sea level, ocean acidification, chemical reaction rates, and precipitation rates, and that it will increasingly do so in the future. The climate and several naturally occurring resources within California are adversely affected by the global warming trend. Increased precipitation and sea level rise will increase coastal flooding, saltwater intrusion, and degradation of wetlands. Mass migration and/or loss of plant and animal species could also occur. Potential effects of global climate change that could adversely affect human health include more extreme heat waves and heat-related stress; an increase in climate-sensitive diseases; more frequent and intense natural disasters such as flooding, hurricanes, and drought; and increased levels of air pollution.
Federal and Statewide GHG Emissions
The U.S. EPA reported that in 2022, total gross nationwide GHG emissions were 6,343 million metric tons (MMT) carbon dioxide equivalent (CO2e).21 These emissions were 17 percent lower than 2005 levels, but 1 percent higher than 2021.

CARB updates the statewide GHG emission inventory on an annual basis where the latest inventory includes 2000 through 2022 emissions.22 In 2022, GHG emissions from statewide emitting activities were 371.1 MMT CO2e, 2.4 percent lower than 2021. Since peak levels in 2004, California’s GHG emissions have generally followed a decreasing trend. In 2014, statewide GHG emissions dropped below the 2020 GHG Limit and have remained below the Limit since that time.
State Regulatory Actions for GHG Emissions
Executive Order S-3-05 – California GHG Reduction Targets Executive Order (EO) S-3-05 was signed by Governor Arnold Schwarzenegger in 2005 to set GHG emission reduction targets for California. The three targets established by this EO are as follows:
(1) reduce California’s GHG emissions to 2000 levels by 2010, (2) reduce California’s GHG emissions to 1990 levels by 2020, and (3) reduce California’s GHG emissions by 80 percent below 1990 levels by 2050.
Assembly Bill 32 – California Global Warming Solutions Act (2006) Assembly Bill (AB) 32, the Global Warming Solutions Act of 2006, codified the State’s GHG emissions target by directing CARB to reduce the State’s global warming emissions to 1990 levels by 2020. AB 32 was signed and passed into law by Governor Schwarzenegger on September 27, 2006. Since that time, the CARB, CEC, California Public Utilities Commission (CPUC), and Building Standards Commission have all been developing regulations that will help meet the goals of AB 32 and Executive Order S-3-05, which has a target of reducing GHG emissions 85 percent below 1990 levels.
The first Scoping Plan for AB 32 was adopted by CARB in December 2008. Its most recent update was completed in December of 202223. It contains the State’s main strategies to achieve carbon neutrality by 2045. This plan extends and expands upon the earlier versions with a target of reducing anthropogenic emissions to 85 percent below 1990 levels by 2045. It also takes the step of adding carbon neutrality as a science-based guide and touchstone for California’s climate work.
Measures to achieve carbon neutrality include rapidly moving to zero emission vehicles (ZEV), removing natural gas as an option for space conditioning, increasing the number of solar arrays and wind turbines, and scaling up renewable hydrogen for hard-to-electrify end uses.
Senate Bill 375 – California's Regional Transportation and Land Use Planning Efforts (2008) California enacted legislation (SB 375) to expand the efforts of AB 32 by controlling indirect GHG emissions caused by urban sprawl. SB 375 provides incentives for local governments and applicants to implement new conscientiously planned growth patterns. This includes incentives for creating attractive, walkable, and sustainable communities and revitalizing existing communities.

build projects consistent with the new sustainable community strategies. Development of more alternative transportation options that would reduce vehicle trips and miles traveled, along with traffic congestion, would be encouraged. SB 375 enhances CARB’s ability to reach the AB 32 goals by directing the agency in developing regional GHG emission reduction targets to be achieved from the transportation sector for 2020 and 2035. CARB works with the metropolitan planning organization (i.e., MTC) to align their regional transportation, housing, and land use plans to reduce VMT and demonstrate the region's ability to attain its GHG reduction targets.
Senate Bills 350 and 100 - Renewable Portfolio Standards In September 2015, the California Legislature passed SB 350, which increased the states Renewables Portfolio Standard (RPS) for content of electrical generation from the 33 percent target for 2020 to a 50 percent renewables target by 2030.
In September 2018, SB 100 was signed by Governor Brown to revise California’s RPS program goals, furthering California’s focus on using renewable energy and carbon-free power sources for its energy needs. The bill requires all California utilities to supply a specific percentage of their retail sales from renewable resources by certain target years. By December 31, 2024, 44 percent of the retails sales would need to be from renewable energy sources, by December 31, 2026 the target would be 40 percent, by December 31, 2027 the target would be 52 percent, and by December 31, 2030 the target would be 60 percent. By December 31, 2045, all California utilities would be required to supply retail electricity that is 100 percent carbon-free and sourced from eligible renewable energy resources to all California end-use customers.
SB 743 Transportation Impacts
Senate Bill 743 required lead agencies to abandon the old “level of service” metric for evaluating a project’s transportation impacts, which was based solely on the amount of delay experienced by motor vehicles. In response, the Governor’s Office of Planning and Research (OPR) developed a VMT metric that considered other factors such as reducing GHG emissions and developing multimodal transportation.24 A VMT-per-capita metric was adopted into the CEQA Guidelines Section 15064.3 in November 2017. Given current baseline per-capita VMT levels computed by CARB in the 2017 Scoping Plan of 22.24 miles per day for light-duty vehicles and 24.61 miles per day for all vehicle types, the reductions needed to achieve the 2050 climate goal are 16.8 percent for light-duty vehicles and 14.3 percent for all vehicle types combined. Based on this analysis (as well as other factors), OPR recommended using a 15-percent reduction in per capita VMT as an appropriate threshold of significance for evaluating transportation impacts.
Executive Order B-55-18 – Carbon Neutrality
In 2018, a new statewide goal was established to achieve carbon neutrality as soon as possible, but no later than 2045, and to maintain net negative emissions thereafter. CARB and other relevant state agencies are tasked with establishing sequestration targets and creating policies/programs that would meet this goal.

Executive Order B-30-15 & Senate Bill 32 GHG Reduction Targets – 2030 GHG Reduction Target In April 2015, Governor Brown signed EO B-30-15, which extended the goals of AB 32, setting a GHG emissions target at 40 percent of 1990 levels by 2030. On September 8, 2016, Governor Brown signed Senate Bill (SB) 32, which legislatively established the GHG reduction target of 40 percent of 1990 levels by 2030. In November 2017, CARB issued California’s 2017 Climate Change Scoping Plan.
25 While the State is on track to exceed the AB 32 scoping plan 2020 targets, this plan is an update to reflect the enacted SB 32 reduction target.
SB 32 was passed in 2016, which codified a 2030 GHG emissions reduction target of 40 percent below 1990 levels. CARB has drafted a 2022 Scoping Plan Update to reflect the 2030 target set by Executive Order B-30-15 and codified by SB 32. The 2022 draft plan:
Identifies a path to keep California on track to meet its SB 32 GHG reduction target of at least 40 percent below 1990 emissions by 2030.
Identifies a technologically feasible, cost-effective path to achieve carbon neutrality by 2045 or earlier.
Focuses on strategies for reducing California’s dependency on petroleum to provide consumers with clean energy options that address climate change, improve air quality, and support economic growth and clean sector jobs.
Integrates equity and protecting California’s most impacted communities as a driving principle.
Incorporates the contribution of natural and working lands to the state’s GHG emissions, as well as its role in achieving carbon neutrality.
Relies on the most up to date science, including the need to deploy all viable tools, including carbon capture and sequestration as well as direct air capture. Evaluates multiple options for achieving our GHG and carbon neutrality targets, as well as the public health benefits and economic impacts associated with each.
The Scoping Plan was updated in 2022 and lays out how the state can get to carbon neutrality by 2045 or earlier. It is the first Scoping Plan that adds carbon neutrality as a science-based guide and touchstone beyond statutorily established emission reduction targets.26 The mid-term 2030 target is considered critical by CARB on the path to obtaining an even deeper GHG emissions target of 80 percent below 1990 levels by 2050, as directed in Executive Order S3-05. The 2022 Scoping Plan outlines the suite of policy measures, regulations, planning efforts, and investments in clean technologies and infrastructure, providing a blueprint to continue driving down GHG emissions and to not only obtain the statewide goals, but cost-effectively achieve carbon-neutrality by 2045 or earlier. In the 2022 Scoping Plan, CARB recommends:
VMT per capita reduced 12% below 2019 levels by 2030 and 22% below 2019 levels by 2045.

100% of Light-duty vehicle sales are zero emissions vehicles (ZEV) by 2035. 100% of medium duty/heavy duty vehicle sales are ZEV by 2040. 100% of passenger and other locomotive sales are ZEV by 2030. 100% of line haul locomotive sales are ZEV by 2035.
All electric appliances in new residential and commercial building begin in 2026 (residential) and 2029 (commercial).
80% of residential appliance sales are electric by 2030 and 100% of residential appliance sales are electric by 2035.
80% of commercial appliance sales are electric by 2030 and 100% of commercial appliance sales are electric by 2045.
California Building Standards Code – Title 24 Part 11 & Part 6 The California Green Building Standards Code (CALGreen Code) is part of the California Building Standards Code under Title 24, Part 11.27 The CALGreen Code encourages sustainable construction standards that involve planning/design, energy efficiency, water efficiency resource efficiency, and environmental quality. These green building standard codes are mandatory statewide and are applicable to residential and non-residential developments. The most recent CALGreen Code (2022 California Building Standard Code) was effective as of January 1, 2023.
The California Building Energy Efficiency Standards (California Energy Code) is under Title 24, Part 6 and is overseen by the CEC. This code includes design requirements to conserve energy in new residential and non-residential developments, while being cost effective for homeowners.
However, the CEC does not mandate specific fuel types. This Energy Code is enforced and verified by cities during the planning and building permit process. The current energy efficiency standards (2022 Energy Code) replaced the 2019 Energy Code as of January 1, 2023. The 2022 Energy Code builds on California’s technology innovations, encouraging inclusion of market-ready electric products in new construction, such as heat pumps for climate control and water heating. Under the 2022 standards, all new homes are required to be electric-ready. That means buildings with gas stoves have electrical panels and wiring to support a switch to electric stoves. This Energy code also strengthens ventilation standards to improve indoor air quality. This update provides crucial steps in the state’s progress toward 100 percent clean carbon neutrality by midcentury.28 CEC studies have identified the most aggressive electrification scenario as putting the building sector on track to reach the carbon neutrality goal by 2045.29 Installing new natural gas infrastructure in new buildings will interfere with this goal. To meet the State’s goal, communities have been adopting “Reach” codes that prohibit natural gas connections in new and remodeled buildings.
Requirements for electric vehicle (EV) charging infrastructure are set forth in Title 24 of the California Code of Regulations and are regularly updated on a 3-year cycle. The CALGreen 27 See: https://www.dgs.ca.gov/BSC/Resources/Page-Content/Building-Standards-Commission-Resources-ListFolder/CALGreen#:~:text=CALGreen%20is%20the%20first%2Din,to%201990%20levels%20by%202020. 28 See: https://www.energy.ca.gov/sites/default/files/2021-08/CEC_2022_EnergyCodeUpdateSummary_ADA.pdf 29 California Energy Commission. 2021.

standards consist of a set of mandatory standards required for new development, as well as two more voluntary standards known as Tier 1 and Tier 2. The CALGreen 2022 standards require deployment of additional EV chargers in various building types, including multifamily residential and nonresidential land uses. They include requirements for both EV capable parking spaces and the installation of Level 2 EV supply equipment for multifamily residential and nonresidential buildings. The 2022 CALGreen standards include both mandatory requirements and more aggressive voluntary Tier 1 and Tier 2 provisions for both EV readiness and the actual installation of EV chargers. Providing EV charging infrastructure that meets current CALGreen requirements will not be sufficient to power the anticipated more extensive level of EV penetration in the future that is needed to meet SB 32 climate goals.
An update to the current CALGreen Energy Code will be effective on January 1, 2026, with the adoption of the 2025 Energy Code.30 The 2025 standards were adopted at the September 11, 2024 CEC business meeting and will go to the California Building Standards Commission for approval as part of California’s Building Standards Code before the end of 2024. It will apply to newly constructed buildings, additions, and alterations and focus on:
Expanding the use of heat pumps for space conditioning and water heating in newly constructed single-family, multifamily, and select nonresidential buildings. Encouraging electric-ready buildings to set up owners to use cleaner electric water heating and cooking when they are ready to invest in those technologies. Updating photovoltaic and battery energy storage system standards for high-rise multifamily and nonresidential buildings to achieve cost effective installations in consideration of revised net billing and virtual net billing rules. Updating space conditioning system control standards for nonresidential buildings. Updating ventilation requirements in multifamily buildings to improve indoor air quality.
Advanced Clean Cars
The Advanced Clean Cars Program, originally adopted by CARB in 2012, was designed to bring together CARB’s traditional passenger vehicle requirements to meet federal air quality standards and also support California’s AB 32 goals to develop and implement programs to reduce GHG emissions back down to 1990 levels by 2020, a goal achieved in 2016 as a result of numerous emissions reduction programs.
Advanced Clean Cars II (ACC II) is phase two of the original rule. ACC II establishes a year-byyear process, starting in 2026, so all new cars and light trucks sold in California will be zeroemission vehicles by 2035. The regulation codifies the light-duty vehicle goals set out in Governor Newsom’s Executive Order N-79-20. Currently, 16 percent of new light-duty vehicles sold in California are zero emissions or plug-in hybrids. By 2030, 68 percent of new vehicles sold in California would be zero emissions and 100 percent by 2035. 30 CEC 2025 California Energy Code Fact Sheet, September 2024. https://www.energy.ca.gov/sites/default/files/2024-09/2025_California_Energy_Code_Fact_Sheet_ada.pdf Item 8.2

Envision Campbell General Plan and Housing Element Update Environmental Impact Report (EIR and Draft EIR)
The EIR for the Envision Campbell General Plan and Housing Element Update analyzed GHG impacts with respect to growth in the City per Appendix G of the State CEQA Guidelines.31 It found that GHG emissions from implementation of the General Plan and Housing Element Update could have a significant and unavoidable impact (Impact 3.7-1). However, implementation of the General Plan and Housing Element Update would not result in any significant adverse impacts related to energy requirements, energy use inefficiencies, and/or the energy intensiveness (Impact
3.7-2).
There are numerous General Plan goals, policies and implementing measures that would minimize potential impacts associated with GHG emissions in the City of Campbell. Development projects are required to comply with State and local regulations for the reduction of GHG emissions.
However, there is no guarantee that implementation of the General Plan and its updated Housing Element would ensure that the City of Campbell would be consistent with California’s long-term climate goal of achieving carbon neutrality by 2045. The goals, policies and implementing measures used to minimize the potential impacts associated with GHG emissions in the City include:
Promoting a compact urban development form, emphasizing infill development. Reducing VMT per service population throughout the City through the use of complete streets and multi-modal transportation systems.
Implementing a connected multi-modal transportation network that balances transportation modes, encourages non-automobile travel, and reduces GHG emissions. Implementing VMT reduction measures, such as Transportation Demand Management (TDM) measures, and other strategies to reduce VMT.
The full list of General Plan and Housing Element Update goals, policies, and implementing measures that minimize potential GHG impacts are provided in Section 3.7 of the DEIR.
City of Campbell Climate Action Plan
The City of Campbell does not currently have a Climate Action Plan or other local GHG reductions strategies that meet the criteria under State CEQA Guidelines Section 15183.5(b) As part of the General Plan and Housing Element Update, the City has committed to develop a Climate Action Plan (CAP) that establishes GHG reduction targets that are consistent with Statewide GHG reduction goals and includes an implementation program to achieve the reduction targets. The City is currently in the process of developing its CAP, with an estimated completion of October 2025.32 When completed, it is likely the plan would meet the requirements of a qualified CAP (i.e., one that meets the criteria under State CEQA Guidelines Section 15183.5(b)). 31 Findings of Fact and Statement of Overriding Considerations for the Envision Campbell General Plan and Housing Element Update.

BAAQMD GHG Significance Thresholds
On April 20, 2022, BAAQMD adopted new thresholds of significance for operational GHG emissions from land use projects for projects beginning the CEQA process. The following framework is how BAAQMD will determine GHG significance moving forward.33 Note BAAQMD intends that the thresholds apply to projects that begin the CEQA process after adoption of the thresholds, unless otherwise directed by the lead agency. The new thresholds of significance are:
A. Projects must include, at a minimum, the following project design elements:
a. Buildings
i. The project will not include natural gas appliances or natural gas plumbing (in both residential and non-residential development).
ii. 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.
b. Transportation
i. 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 recommendations provided in the Governor’s Office of Planning and Research’s Technical Advisory on Evaluating Transportation Impacts in CEQA:
1. Residential Projects: 15 percent below the existing VMT per capita
2. Office Projects: 15 percent below the existing VMT per employee
3. Retail Projects: no net increase in existing VMT
ii. Achieve compliance with off-street electric vehicle requirements in the most recently adopted version of CALGreen Tier 2.
B. Be consistent with a local GHG reduction strategy that meets the criteria under State CEQA Guidelines Section 15183.5(b).
Any new land use project would have to include either section A or B from the above list, not both, to be considered in compliance with BAAQMD’s GHG thresholds of significance.
Impact GHG-1: Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
GHG emissions associated with development of the proposed project would occur over the shortterm from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal. 33 Justification Report: BAAQMD CEQA Thresholds for Evaluating the Significance of Climate Impacts from Land Use Project and Plans.

GHG emissions associated with construction were computed at 802 MT of CO2e for the total construction period. These are the emissions from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. Neither the City nor BAAQMD have an adopted threshold of significance for construction-related GHG emissions, though the California Office of Planning and Research (OPR) recommends quantifying emissions and disclosing that GHG emissions would occur during construction, even in cases where BAAQMD does not. BAAQMD also encourages the incorporation of best management practices to reduce GHG emissions during construction where feasible and applicable.
The project is a Housing Element site, and therefore the impacts associated with the Project were included in the GHG analysis of the City’s General Plan and Housing Element Update. As a whole, the General Plan and Housing Element Update was found to have a significant and unavoidable GHG emissions impact. In order to minimize the GHG impacts, the Project would need to adhere to the goals, policies, and implementing measures listed in the General Plan.
Projects consistent with the City of Campbell’s General Plan do not require a VMT analysis. The City’s Environmental Impact Review (March 2023)found that VMT impacts would be significant and unavoidable.34 Because the Project’s VMT impacts were considered in the analysis of the Updated Housing Element, it would not generate unanticipated new VMT, and therefore would not require mitigation. Policy T-3.2 of the 2040 General Plan requires the implementation of VMT reduction measures, such as Transportation Demand Management (TDM) measures, and other strategies to reduce VMT in Campbell. Thus, the project would need to develop Project-specific VMT reduction measures, such as a TDM plan based on the adopted General Plan policies.
The City anticipates adoption of its CAP in late 2025. The CAP may have project-specific requirements or a checklist that must be adhered to prior to acquiring building permits. Adherence to the CAP’s project-level requirements would meet requirement B of BAAQMD’s CEQA significance threshold for GHG emissions, making its impact less than significant.
The project also complies with the BAAQMD’s GHG Threshold A, since the project demonstrates the following:
1. Avoid construction of new natural gas connections for the residential building, Conforms – According to the project applicant, the project will be all-electric and not include new natural gas connections.
2. Avoid wasteful or inefficient use of electricity,
Conforms – would meet CALGreen Building Standards Code requirements that are considered to be energy efficient.
3. Include electric vehicle charging infrastructure that meets current Building Code CALGreen Tier 2 compliance, and
Conforms – The project’s parking would meet the Tier 2 compliance standard and each garage unit will be equipped for EV charging infrastructure.
4. Reduce VMT per capita by 15 percent over baseline conditions. 34 URL: https://www.campbellca.gov/DocumentCenter/View/19998/Findings-of-Fact-and-Statements-ofOverriding-Consideration---03-14-2023 Item 8.2
Tuesday, January 20, 2026 485 of 681
Conforms with implementation of a TDM plan – the Project is consistent with the City of Campbell’s General Plan. The City’s General Plan does not require a project-level VMT analysis but does require the project to develop and implement VMT reduction measures, such as a transportation demand management (TDM) plan.
With the VMT reduction measures/TDM plan, the project is anticipated to comply with the requirements of Threshold A. As a result, the Project would have a less-than-significant impact for the project’s GHG impacts.
Impact GHG-2: Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
The proposed project would be constructed in conformance with 2025 CALGreen, 2022 CALGreen, and Title 24 Building Codes, which requires high-efficiency water fixtures, waterefficient irrigation systems, and compliance with current energy efficiency standards. Compliance with these standards ensures compliance with State and federal plans, policies, and regulations applicable to GHG emissions. Additionally, the City of Campbell is also a member agency of the Silicon Valley Clean Energy (SVCE). Households and businesses receive carbon-free electricity through the SVCE program, reducing indirect GHG emissions.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 12.6 annual days of extreme heat Extreme Precipitation 5.85 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 12.6 annual days of extreme heat Extreme Precipitation 5.85 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

g. This spray booth is considered to be insignificant.
4. Permitted sources include diesel back-up generators, gas stations, dry cleaners, boilers, printers, auto spray booths, etc.11. Further information about common sources:
a. Sources that only include diesel internal combustion engines can be adjusted using the BAAQMD's Diesel Multiplier worksheet.b. The risk from natural gas boilers used for space heating when <25 MM BTU/hr would have an estimated cancer risk of one in a million or less, and a chronic hazard index of 0.003 or less.
Therefore, there is no cancer risk, hazard or PM2.5 concentrations from co-residential dry cleaning businesses in the BAAQMD. d. Non co-residential dry cleaners must phase out use of perc by Jan. 1, 2023. Therefore, the risk from these dry cleaners does not need to be factored in over a 70-year period, but instead should reflect the e. Gas stations can be adjusted using BAAQMD's Gas Station Distance Mulitplier worksheet.
6. If a Health Risk Screening Assessment (HRSA) was completed for the source, the application number will be listed here.7. The date that the HRSA was completed.8. Engineer who completed the HRSA. For District purposes only.9. All HRSA completed before 1/5/2010 need to be multiplied by an age sensitivity factor of 1.7.10. The HRSA "Chronic Health" number represents the Hazard Index.5. Fuel codes: 98 = diesel, 189 = Natural Gas.

Comments:2. These Cancer Risk, Hazard Index, and PM2.5 columns represent the values in the Google Earth Plant Information Table.3. Each plant may have multiple permits and sources. f. Unless otherwise noted, exempt sources are considered insignificant. See BAAQMD Reg 2 Rule 1 for a list of exempt sources.

Exterior Noise and Exterior Façade Acoustical Analysis
Veneklasen Project No. 4616-036
Dear Pamela:
Veneklasen Associates, Inc. (Veneklasen) has completed the review of the 700 West Hamiton Road project located in Campbell, California. This report predicts the exterior noise level at the site using measurements. Using this information, interior noise levels were calculated based on the exterior noise exposure and the construction types proposed. From this, the exterior façade design was determined. This report discusses the results of the analysis.
1.0 INTRODUCTION
This study was conducted to determine the impact of the exterior noise sources on the 700 West Hamiton Road project in Campbell, California. Veneklasen’s scope of work included calculating the exterior noise levels impacting the site and determining the method, if any, required to reduce the interior and exterior sound levels to meet the applicable code requirements of the State of California and the City of Campbell.
The project consists of seven townhome buildings and one podium-style apartment building with a podium over garage and a residential lobby. The project is bounded by West Hamilton Avenue to the north, the San Tomas Expressway to the east, Gale Drive to the south, and existing residential and commercial uses to the west.
2.0 NOISE CRITERIA
CNEL (Day-Night Level) is the 24-hour equivalent (average) sound pressure level in which the nighttime (10 pm – 7 am) noise is weighted by adding 10 dB to the hourly level. Since this is a 24-hour metric, shortduration noise events (truck pass-bys, buses, trains, etc.) are not as prominent in the analysis.
Leq (equivalent continuous sound level) is defined as the steady sound pressure level which, over a given period of time, has the same total energy as the actual fluctuating noise.
All reported noise levels are A-weighted.
2.1 Interior Noise Levels – Residential
The State of California Building Code (Title 24, Part 2, Section 1206 “Sound Transmission”), The City of Campbell Municipal Code § 21.16.70.E, and the City of Campbell Noise Element policy N-1.4 state that interior CNEL for residential land uses are not to exceed 45 dB in any habitable room.
If the windows must be closed to meet an interior CNEL of 45 dB, then a mechanical ventilating system or other means of natural ventilation may be required.
2.2 CALGreen – Non-Residential
The California Green Building Standards Code (CALGreen Section 5.507.4.2) stipulates that for buildings exposed to a noise level of 65 dB or more when measured as a 1-hour Equivalent Sound Level (Leq), the Item 8.2

building façade, including walls, windows, and roofs, shall provide enough sound insulation so that the interior sound level from exterior sources does not exceed 50 dB during any hour of operation. This applies to non-residential spaces such as retail space, leasing, and amenities.
3.0 EXTERIOR NOISE ENVIRONMENT
3.1 Noise Measurements
Traffic on San Tomas Expressway is the primary source of noise affecting the site. Veneklasen visited the site on Monday, September 30, 2024 and placed meters on the roof of the existing building to capture the hourly sound levels on the site for a 24-hour period. Veneklasen also completed short-term noise measurements.
Table 1 and Figure 1 show the location and summary of the noise measurements.

3.2 Overall Exterior Exposure
Based on the computer model and measurements, Veneklasen calculated the noise level at different locations across the project site. To simplify the presentation of the exterior noise levels, Veneklasen has separated the site into locations based on the sound exposure and required mitigation. The predicted sound levels at each zone, shown in Figure 2, are listed in Table 2 below.

4.0 INTERIOR NOISE CALCULATION
4.1 Exterior Façade Construction
Calculations were based on the plans dated September 11, 2024. The plans do not show the exterior wall construction, but indicate shingle siding, board and batten, lap siding, or stucco. Veneklasen has assumed that the exterior walls will consist of one of the listed finishes over sheathing on wood studs with a single layer of gypsum board on the interior and batt insulation in the cavity. 1 LoVerde, John; Dong, Wayland; Rawlings, Samantha.

Veneklasen’s analysis included the roof path, but this was insignificant in the interior noise level calculated.
Veneklasen received the planned windows used on the project on February 27, 2025. Milgard V300 TrinsicTM windows will be selected for the project. Appendix I specifies the selected window series and corresponding STC ratings.
4.2 Interior Average Noise Level (CNEL) – Residential
Veneklasen calculated the interior level within the residential units given the measured noise environment and the exterior façade construction described above. Table 3 shows the predicted interior CNEL based on the windows and doors with STC ratings as shown and glazing construction as described in Appendix I. The selected windows meet the City and State requirements with no further mitigation.

Zone C 61-67 STC 30 STC 33 < 40
Remaining Units ≤ 60 No STC
requirement STC 33 < 40
4.3 Mechanical Ventilation – Residential
Because the windows and doors must be kept closed to meet the noise requirements, mechanical or other means of ventilation will be used for units in Zones A, B, and C. The ventilation system will not compromise the sound insulation capability of the exterior façade assembly.
4.4 CALGreen – Non-Residential
In a similar manner, Veneklasen calculated the noise level within non-residential spaces. CALGreen is based on the loudest hourly Leq. Veneklasen utilized a statistical methodology to determine this level from the measurements3. The results are shown in Table 4 below. The selected windows meet the State requirements with no further mitigation.
