1 Introduction
The purpose of this report is to address air quality, health risk, and greenhouse gas (GHG) impacts associated with the proposed Cotati Village #2 project located at 7515 Alder Avenue in Cotati, California. Air quality and GHG would be associated with the construction of new buildings and infrastructure, and operation of the project. Air pollutants and GHG emissions associated with construction and operation of the project were predicted using appropriate computer models. In addition, the potential project health risk impacts (construction and operation) and the impact of existing toxic air contaminant (TAC) sources affecting the nearby and proposed sensitive receptors were evaluated. The analysis was conducted following guidance provided by the Bay Area Air Quality Management District (BAAQMD).1
Project Description
The approximately 4-acre project site is located on a vacant parcel. The project proposes to construct two, four-story buildings totaling 126 residential units and a separate 2,250 square-foot (sf) café. It would also include 168 parking spaces throughout the site.
Setting
The project is located in the portion of Sonoma County that is part of 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). In Sonoma County, measured levels of air pollutants are below air quality standards, including ozone, PM10 and 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, reduced 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 function growth in children. 1 Bay Area Air Quality Management District, 2022 CEQA Guidelines, April 2023. 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 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 threequarters of the cancer risk from TACs (based on the Bay Area average). 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 CEQA guidance.2
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, elementary schools, and parks. For cancer risk assessments, 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 to the site are the residents in the townhomes northeast of the project site, with additional single-family homes in the surrounding area. If the Cotati Village #1 project adjacent to the east of the site is completed before this project begins, it would also have sensitive receptors. The project will introduce new sensitive (i.e., residential) receptors.
Regulatory Setting
Federal Regulations
The United States Environmental Protection Agency (EPA) sets nationwide emission standards for mobile sources, which include on-road (highway) motor vehicles such trucks, buses, and automobiles, and non-road (off-road) vehicles and equipment used in construction, agricultural, industrial, and mining activities (such as bulldozers and loaders). The EPA also sets nationwide 2 OEHHA, 2015. Air Toxics Hot Spots Program Risk Assessment Guidelines, The Air Toxics Hot Spots Program Guidance Manual for Preparation of Health Risk Assessments. Office of Environmental Health Hazard Assessment.
February.
3 fuel standards. California also has the ability to set motor vehicle emission standards and standards for fuel used in California, as long as they are the same or more stringent than the federal standards.
In the past decade the EPA has established a number of emission standards for on- and non-road heavy-duty diesel engines used in trucks and other equipment. This was done in part because diesel engines are a significant source of NOX and particulate matter (PM10 and PM2.5) and because the EPA has identified DPM as a probable carcinogen. Implementation of the heavy-duty diesel onroad vehicle standards and the non-road diesel engine standards are estimated to reduce particulate matter and NOX emissions from diesel engines up to 95 percent in 2030 when the heavy-duty vehicle fleet is completely replaced with newer heavy-duty vehicles that comply with these emission standards.3
In concert with the diesel engine emission standards, the EPA has also substantially reduced the amount of sulfur allowed in diesel fuels. The sulfur contained in diesel fuel is a significant contributor to the formation of particulate matter in diesel-fueled engine exhaust. The new standards reduced the amount of sulfur allowed by 97 percent for highway diesel fuel (from 500 parts per million by weight [ppmw] to 15 ppmw), and by 99 percent for off-highway diesel fuel (from about 3,000 ppmw to 15 ppmw). The low sulfur highway fuel (15 ppmw sulfur), also called ultra-low sulfur diesel (ULSD), is currently required for use by all vehicles in the U.S.
All of the above federal diesel engine and diesel fuel requirements have been adopted by California, in some cases with modifications making the requirements more stringent or the implementation dates sooner.
State Regulations
To address the issue of diesel emissions in the state, CARB developed the Risk Reduction Plan to Reduce Particulate Matter Emissions from Diesel-Fueled Engines and Vehicles.4 In addition to requiring more stringent emission standards for new on-road and off-road mobile sources and stationary diesel-fueled engines to reduce particulate matter emissions by 90 percent, a significant component of the plan involves application of emission control strategies to existing diesel vehicles and equipment. Many of the measures of the Diesel Risk Reduction Plan have been approved and adopted, including the federal on-road and non-road diesel engine emission standards for new engines, as well as adoption of regulations for low sulfur fuel in California.
CARB has adopted and implemented a number of regulations for stationary and mobile sources to reduce emissions of DPM. Several of these regulatory programs affect medium and heavy-duty diesel trucks that represent the bulk of DPM emissions from California highways. CARB regulations require on-road diesel trucks to be retrofitted with particulate matter controls or replaced to meet 2010 or later engine standards that have much lower DPM and PM2.5 emissions.
This regulation will substantially reduce these emissions between 2013 and 2023. While new trucks and buses will meet strict federal standards, this measure is intended to accelerate the rate 3 USEPA, 2000. Regulatory Announcement, Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements. EPA420-F-00-057. December. 4 California Air Resources Board, 2000. Risk Reduction Plan to Reduce Particulate Matter Emissions from DieselFueled Engines and Vehicles. October. 4 at which the fleet either turns over so there are more cleaner vehicles on the road or is retrofitted to meet similar standards. With this regulation, older, more polluting trucks would be removed from the roads sooner.
CARB has also adopted and implemented regulations to reduce DPM and NOX emissions from inuse (existing) and new off-road heavy-duty diesel vehicles (e.g., loaders, tractors, bulldozers, backhoes, off-highway trucks, etc.). The regulations apply to diesel-powered off-road vehicles with engines 25 horsepower (hp) or greater. The regulations are intended to reduce particulate matter and NOX exhaust emissions by requiring owners to turn over their fleet (replace older equipment with newer equipment) or retrofit existing equipment in order to achieve specified fleetaveraged emission rates. Implementation of this regulation, in conjunction with stringent federal off-road equipment engine emission limits for new vehicles, will significantly reduce emissions of DPM and NOX.
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, 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 and California Ambient Air Quality Standards. The District also has permit authority over most types of stationary equipment utilized for projects. 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 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 not within any of the BAAQMD CARE areas.
5 See BAAQMD: https://www.baaqmd.gov/community-health/community-health-protection-program/communityair-risk-evaluation-care-program. 5 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 38th 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 the 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 including thresholds of significance, mitigation measures, and background air quality information. They include assessment methodologies for criteria air pollutants, air toxics, odors, and GHG emissions as shown in Table
1.8 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 air quality impacts were found to be significant.

7 City of Cotati 2013 General Plan
The 2013 Cotati General Plan Conservation Element includes an extensive list of policies and action measures that are aimed at improving air quality. Additionally, the General Plan Land Use Element and Land Use Map promotes a compact urban development pattern that emphasizes infill development and ensures that land use patterns do to not expose sensitive receptors to unhealthy pollutant concentrations. Furthermore, the Circulation Element includes a range of policies and action items that would effectively reduce vehicle travel, through the use of complete streets and multi-modal transportation systems. Applicable General Plan policies include:
Policy CON 2.1: Improve air quality through continuing to require a compact development pattern that focuses growth in and around existing urbanized areas, locating new housing near places of employment, encouraging alternative modes of transportation, and requiring projects to mitigate significant air quality impacts.
Policy CON 2.2: Minimize exposure of sensitive receptors to concentrations of air pollutant emissions and toxic air contaminants.
Policy CON 2.4: Require new development or significant remodels to install fireplaces, stoves, and/or heaters which meet current BAAQMD standards. Policy CON 2.5: Continue to require all construction projects and ground disturbing activities to implement BAAQMD dust control and abatement measures. Policy CON 2.7: Continue to aggressively implement the greenhouse gas (GHG) reduction measures contained in the 2008 Cotati Greenhouse Gas Emissions Reduction Action Plan. Policy CON 3.1: Continue to require all new public and privately constructed buildings to meet and comply with CALGreen Tier 1 standards.
Policy CON 3.2: Support innovative and green building best management practices, including LEED certification, for all new development, and encourage project applicants to exceed CALGreen Tier 1 standards, if feasible.
Policy CON 3.3: Promote the use of alternative energy sources in new development. Policy CON 3.7: Encourage tree planting, including widespread use of trees as windbreaks to maximize the effects of cooling westerly winds and planting of deciduous trees to help reduce summer temperatures, either in conjunction with new development or through private sector participation.
Policy CON 3.8: Promote water conservation among water users. Policy CON 3.9: Require the use of drought-tolerant and regionally native plants in landscaping.
Policy CON 3.10: Ensure that the layout and design of new development and significant remodels encourages the use of transportation modes other than automobiles and trucks. Policy CON 3.16: Improve and maintain landscaping around commercial areas in order to minimize the "heat island" effect, provide shade, soften the harshness of such commercial areas, and create a more leisurely ambience.
8 AIR QUALITY IMPACTS
Impact AIR-1: Conflict with or obstruct implementation of the applicable air quality plan?
BAAQMD, with assistance from the Association of Bay Area Governments (ABAG) and Metropolitan Transportation Commission (MTC), implements specific plans to meet the applicable federal and State laws, regulations, and programs. The most recent and comprehensive plan is the Bay Area 2017 Clean Air Plan.
9 The primary goals of the Clean Air Plan are to attain air quality standards, reduce population exposure and protect public health, and reduce GHG emissions and protect the climate. The BAAQMD has also recently updated its CEQA guidelines to assist lead agencies in evaluating the significance of air quality impacts. In formulating compliance strategies, BAAQMD relies on planned land uses established by local general plans. Land use planning affects vehicle travel, which in turn affects region-wide emissions of air pollutants and GHGs.
The 2017 Clean Air Plan, adopted by BAAQMD in April 2017, includes control measures that are intended to reduce air pollutant emissions in the Bay Area either directly or indirectly. Plans must show consistency with the control measures listed within the Clean Air Plan. At the project-level, there are no consistency measures or thresholds. The proposed project would not conflict with the latest Clean Air planning efforts since 1) project would have construction and operational emissions below the BAAQMD thresholds and 2) the project would be considered urban infill, and 3) the project would be located near employment centers.
Impact AIR-2: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? The Bay Area is considered a non-attainment area for ground-level O3 and PM2.5 under both the NAAQS and the CAAQS. The area is also considered non-attainment for PM10 under the CAAQS, but not the NAAQS. The area has attained both the NAAQS and CAAQS for carbon monoxide (CO). As part of an effort to attain and maintain the NAAQS and CAAQS for O3, PM2.5 and PM10, the BAAQMD has established thresholds of significance for these air pollutants and their precursors. These thresholds are for O3 precursor pollutants (ROG and NOX), PM10, and PM2.5 and apply to both construction period and operational period impacts.
Construction Period Emissions
The California Emissions Estimator Model (CalEEMod) Version 2022 was used to estimate emissions from on-site construction activity, construction vehicle trips, and evaporative emissions.
The project land use types and size, and anticipated construction schedule were input to CalEEMod. The CalEEMod model output along with construction inputs are included in Attachment 1.

Land Uses
The proposed project land uses were entered into CalEEMod as described in Table 2.

Construction Inputs
CalEEMod computes annual emissions for construction that are based on the project type, size, and acreage. The model provides emission estimates for both on-site and off-site construction activities. On-site activities are primarily made up of construction equipment emissions, while offsite activity includes worker, hauling, and vendor traffic. The construction build-out scenario, including equipment quantities, average hours per day, total number of workdays, and schedule, were based on a blend of CalEEMod defaults and information provided by the project applicant (included in Attachment 1). The construction schedules assumed that the earliest possible start date would be January 2025 and the project would be built out over a period of approximately 10 months or 216 construction workdays. The earliest full year of project operation was assumed to be 2026.
Construction Traffic Emissions
Construction would produce traffic in the form of worker trips and truck traffic. The traffic-related emissions are based on worker and vendor trip estimates produced by CalEEMod and haul trips that were computed based on the amount of estimated demolition material to be exported, soil imported and/or exported to the site, and amount of concrete truck trips to and from the site.
CalEEMod provides daily estimates of worker and vendor trips for each applicable phase. Haul trips for demolition and grading were estimated by CalEEMod using the provided demolition soil import/export volumes. The number of total concrete haul trips was provided for the project and converted to daily one-way trips, assuming two trips per delivery. These values are shown in the project construction equipment worksheets included in Attachment 1.
Summary of Computed Construction Period Emissions
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 uncontrolled 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 uncontrolled 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 in the form of PM10 and PM2.5. Sources of fugitive dust 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 airborne dust after it dries. The BAAQMD recommends all projects include a “basic” set of best management practices (BMPs) to manage fugitive dust and considers impacts from dust (i.e., fugitive PM10 and PM2.5) to be less-than-significant if BMPs are implemented.
General Plan Policy CON 2.5 requires projects to implement BAAQMD dust control measures.
Furthermore, the Project intends to implement a Construction Emissions Minimization Plan that includes measures that are consistent with the BAAQMD-recommended basic control measures for reducing fugitive particulate matter.
Operational Period Emissions
ROG, PM, and NOX emissions from the project would be generated primarily from autos driven by future residents. Evaporative emissions from architectural coatings and maintenance products (classified as consumer products) are also typical ROG emission sources from these types of land uses. CalEEMod was used to estimate emissions from operation of the proposed project assuming full build-out.
CalEEMod Inputs
Land Uses
The project operational land uses were entered into CalEEMod as described above for the construction period modeling.
Model Year
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 model, the higher the emission rates utilized by CalEEMod. The earliest full year of operation would be 2026 if construction begins in 2025. Emissions associated with build-out later than 2026 would be lower.
11 Traffic Information
CalEEMod allows the user to enter specific vehicle trip generation rates. Therefore, the projectspecific daily trip generation rate provided by the traffic consultant was entered into the model.10 The project would produce approximately 1,773 daily trips. When accounting for the Internal Capture and Diverted Link Reductions, the project would then produce 1,180 new daily trips. The daily trip generation was calculated using ITE trip generation rates, the size of the project land uses, and the adjusted total automobile trips after reductions. The Saturday and Sunday trip rates were derived by multiplying the ratio of the CalEEMod default rates for Saturday and Sunday trips to the default weekday rate with the project-specific daily weekday trip rate. The default trip lengths and trip types specified by CalEEMod were used.
Energy
CalEEMod defaults for energy use were used, which include the 2019 Title 24 Building Standards.
GHG emissions modeling includes those indirect emissions from electricity consumption. The CalEEMod default emission factor of 39.46 pounds of CO2 per megawatt of electricity produced by Sonoma Clean Power was used.
The project will be all electric according to the project applicant. Therefore, natural gas for the residential and cafe land use was set to zero and the energy use associated with natural gas reassigned to electricity use in CalEEMod.
Wood-Burning Devices
CalEEMod default inputs assume new residential construction would include woodburning fireplaces and stoves. The project would not include wood-burning devices, as these devices are prohibited by BAAQMD Regulation 6, Rule 3.11 Therefore, the number of woodstoves and woodburning fireplaces in CalEEMod were set to zero.
Other Inputs
Default model assumptions for emissions associated with solid waste generation use were used.
Wastewater treatment was changed to 100 percent aerobic conditions to represent the use of city sewer services (i.e., project would not send wastewater to septic tanks or facultative lagoons).
Summary of Computed Operational Emissions
Annual emissions were predicted using CalEEMod and daily emissions were estimating assuming 365 days of operation. Table 4 shows uncontrolled net average daily operational emissions of ROG, NOX, total PM10, and total PM2.5 during operation of the project. The uncontrolled operational period emissions would not exceed the BAAQMD significance thresholds. 10 Email correspondence from Heather Gurewitz, M-Group., May 23, 2024.

Impact AIR-3: Expose sensitive receptors to substantial pollutant concentrations? Project impacts related to increased health risk can occur by generating emissions of TACs and air pollutants. This project would introduce new sources of TACs during construction (e.g., on-site construction and truck hauling emissions) and operation (e.g., mobile sources). Project construction activity would generate dust and equipment exhaust that would affect nearby sensitive receptors. The project would not include stationary sources but would generate some traffic consisting of mostly light-duty gasoline-powered vehicles, which would produce TAC and air pollutant emissions.
Project impacts to existing sensitive receptors were addressed for temporary construction activities and long-term operational conditions. There are also several sources of existing TACs and localized air pollutants in the vicinity of the project. The impact of the existing sources of TACs was assessed in terms of the cumulative risk which includes the project contribution, as well as the risk on the new sensitive receptors introduced by the project.
Health Risk Methodology for Construction and Operation
Health risk impacts were addressed by predicting increased cancer risk, the increase in annual PM2.5 concentrations, and computing the Hazard Index (HI) for non-cancer health risks. The risk impacts from the project are the combination of risk from construction and operation sources.
These sources include on-site construction activity, construction truck hauling, and increased traffic from the project. To evaluate the increased cancer risks from the project, a 30-year exposure period was used, per BAAQMD guidance,12 with the sensitive receptors being exposed to both project construction and operation emissions during this timeframe.
The project increased cancer risk is computed by summing the project construction cancer risk and operation cancer risk contribution. Unlike the increased maximum cancer risk, the annual PM2.5 concentration, and HI values are not additive but based on an annual maximum value for the entirety of the project. The project maximally exposed individual (MEI) is identified as the sensitive receptor that is most impacted by the project’s construction and operation. 12 BAAQMD, 2022. BAAQMD CEQA Air Quality Guidelines Appendix E. April 2023. 13 The methodology for computing health risks impacts is contained in Appendix E of the BAAQMD CEQA Guidelines. TAC and PM2.5 emissions are calculated, a dispersion model used to estimate ambient pollutant concentrations, and cancer risks and HI calculated using DPM concentrations.
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 nearby existing residences surrounding the project site and the future Cotati Village #1 residences, as shown in Figure 1.13 Residential receptors are assumed to include all receptor groups (e.g., third trimester, infants, children, and adults) with almost continuous exposure to project emissions. 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.
Health Risks from Project Construction
The primary health risk impact associated with construction projects are cancer risks associated with diesel exhaust (i.e., DPM), which is a known TAC, and exposure to high ambient concentrations of dust (i.e., PM2.5). DPM poses both a potential health and nuisance impact to nearby receptors. A health risk assessment of the project construction activities was conducted that evaluated potential health effects to nearby sensitive receptors from construction emissions of DPM and PM2.5.
14 This assessment included dispersion modeling to predict the offsite and onsite concentrations resulting from project construction, so that increased cancer risks and non-cancer health effects could be estimated.
Construction Emissions
The CalEEMod model provided total uncontrolled annual PM10 exhaust emissions (assumed to be DPM) for the off-road construction equipment and for exhaust emissions from on-road vehicles.
Total DPM emissions were estimated to be 0.04 tons (72 pounds) and fugitive dust emissions (PM2.5) to be 0.09 tons (173 pounds) from all construction stages. 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 half a 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.
Dispersion Modeling
The U.S. EPA’s AERMOD model is the preferred model from predicting DPM and PM2.5 concentrations. Due to the relatively rural nature of the surrounding area, the closest representative BAAQMD AERMOD meteorological data set are for Sonoma County Airport in Santa Rosa which has a quite different winds than the Project site area. Meteorological data collected by BAAQMD is available for Valley Ford, which is considered much more representative of the Project site. Use of this meteorological data set requires use of a slightly different dispersion model. The U.S. EPA 13 Cotati Village #1 is anticipated to be almost completely constructed when construction begins. 14 DPM is identified by California as a toxic air contaminant due to the potential to cause cancer. 14 ISCST3 dispersion model was used to predict DPM and PM2.5 concentrations at sensitive receptors (residences) in the vicinity of the project construction area. The ISCST3 dispersion model is a BAAQMD-recommended model for use in modeling analysis of these types of emission activities for CEQA projects when meteorological data suitable for use with the AERMOD model are not available.15 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 emission release height of 20 feet (6 meters) was used for the area sources.16 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 ISCST3 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, should be based on the height the exhaust plume is expected to achieve, not just the height of the top of the exhaust pipe.
For modeling fugitive PM2.5 emissions, a near-ground level release height of 7 feet (2 meters) was used for the area source. 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 fugitive dust 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 exit 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.
Emissions from the construction equipment and on-road vehicle travel were distributed throughout the modeled area sources.
ISCST3 Inputs and Meteorological Data
Health risk impacts from construction were based on the construction emissions computed by CalEEMod and modeled with the ISCST3 model using 5 years of meteorological data (1990-1994) from the BAAQMD Valley Ford meteorological station. The Valley Ford station is about 10 miles west-southwest from the project site. DPM and PM2.5 emissions from construction activities during the 2025 period were modeled as area sources. Concentrations were calculated at nearby residential receptors at receptor heights of 1.5 and 4.5 meters, representative of the breathing heights of residents in first and second floor levels. Construction was assumed to occur for 12 hours per day (7:00am – 7:00pm).

Summary of Construction Health Risk Impacts
The maximum increased cancer risks were calculated using the modeled TAC concentrations combined with BAAQMD CEQA guidance for age-sensitivity factors and exposure parameters.
Non-cancer health hazards and maximum PM2.5 concentrations were also calculated and identified.
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.
16 The maximum modeled annual PM2.5 concentration was calculated based on combined exhaust and fugitive concentrations. The maximum computed HI values was based on the ratio of the maximum DPM concentration modeled and the chronic inhalation DPM refence exposure level of 5 µg/m3 .
The modeled maximum annual DPM and PM2.5 concentrations were identified at nearby sensitive receptors to find the MEI from construction activities. Results of this assessment indicated that the cancer risk MEI and annual PM2.5 concentration MEI occurred at the same location on two different floors. The construction cancer risk MEI was located on the second floor (15 feet) of a residence in the southwest corner of the existing townhomes along Alder Avenue. The annual PM2.5 concentration MEI was located at the same location on the first floor (5 feet). The location of the MEIs and nearby sensitive receptors are shown in Figure 1. Table 5 lists the health risks from construction at the location of the residential MEIs. Attachment 2 to this report includes the emission calculations used for the construction modeling and the cancer risk calculations.
Health Risks from Project Operation
The Project would not include stationary sources (e.g., emergency generators) of TACs. Diesel powered vehicles are the primary concern with local traffic-generated TAC impacts. This project would generate 1,773 daily trips or 1,180 net daily trips.17 The project traffic would be dispersed on the roadway system with a majority of the trips being from light-duty vehicles (e.g., passenger automobiles). In addition, projects with the potential to cause or contribute to increased cancer risk from traffic include those that have high numbers of diesel-powered on road trucks or use off-road diesel equipment on site, such as a warehouse distribution center, a quarry, or a manufacturing facility, may potentially expose existing or future planned receptors to substantial cancer risk levels and/or health hazards. This is not a project of concern for mobile sources given the low trip quantity and type of trips generated by the project. Therefore, emissions from project traffic are considered negligible and not included within this analysis.
Summary of Project-Related Health Risks at the Off-Site Project MEIs For this project, the sensitive receptors identified in Figure 1 as the construction MEIs are also the project MEIs. At this location, the MEIs would be exposed to one year of project construction.
The annual PM2.5 concentration and HI values are based on an annual maximum risk for the entirety of the project. As shown in Table 5, the uncontrolled maximum cancer risks and annual PM2.5 concentration from construction activities would exceed their respective BAAQMD singlesource significance thresholds. However, with the implementation of the Condition of Approval (COA) AQ-1, the controlled risk and hazard values would reduce emissions such that cancer risk and PM2.5 concentration caused by construction would no longer exceed the BAAQMD singlesource significance thresholds. The uncontrolled HI does not exceed the BAAQMD single-source significance threshold.

COA AQ-1: Implement a Construction Emissions Minimization Plan that includes dust control measures and use of construction equipment that has low diesel particulate matter exhaust emissions.
To reduce construction emissions and dust generation, the Project shall implement a Construction Minimization Plan. This plan is intended to implement BAAQMD recommended measures to control dust generation and measures to reduce diesel exhaust emissions that may affect nearby residences or other sensitive receptors.
Measures to Control Dust
During any construction period ground disturbance, the applicant shall ensure that the project contractor implements measures to control dust and exhaust that are recommended by BAAQMD and listed below:
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. 18 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.
The measures above are consistent with BAAQMD-recommended basic BMPs for reducing fugitive dust contained in the BAAQMD CEQA Air Quality Guidelines. For this analysis, only the basic set of BMPs are required.
Measures to Control Exhaust Emissions
The Project will implement feasible measures to reduce diesel particulate matter emissions from new construction by 45 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 emission standards for PM (PM10 and PM2.5), if feasible. If Tier 4 equipment is not available for a particular piece of equipment, then use equipment that meets U.S. EPA emission standards for Tier 2 or 3 engines and include particulate matter emissions control equivalent to CARB Level 3 verifiable diesel emission control devices that altogether achieve a 45 percent reduction in particulate matter exhaust in comparison to uncontrolled equipment; alternatively (or in combination).
2. 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 45 percent or greater. Elements of the plan could include a combination of some of the following measures:
• 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.
19 Effectiveness of COA AQ-1:
The Project will implement a Construction Emissions Minimization Plan. This plan would reduce both exhaust and dust (including PM2.5) emissions. The plan includes the use of BAAQMDrecommended measures to minimize dust generation and use of construction equipment that meets U.S. EPA Tier 4 engine standards for particulate matter emissions. Effects of this plan were included in the CalEEMod modeling.
CalEEMod was used to compute emissions associated with the implementation of COA AQ-1, assuming that all equipment meets U.S. EPA Tier 4 interim engines standard and BAAQMD basic BMPs for construction were included. With these measures implemented, the project’s total construction cancer risk levels (assuming infant exposure) would be reduced by 73 percent to 4.41 chances per million and annual PM2.5 concentrations would be reduced by 65 percent to 0.16 µg/m3
. An alternative plan that reduces DPM emissions from construction by 45 percent would reduce total cancer risk to about 9.05 chances per million and annual PM2.5 concentrations to 0.25 µg/m3
, which would be below the BAAQMD single-source significance thresholds. The impact would be reduced to a level of less-than-significant with implementation of COA AQ-1.
Cumulative Health Risks of all TAC Sources at the Off-Site Project MEI Cumulative health risk assessments typically look at all substantial sources of TACs that can affect sensitive receptors located within 1,000 feet of a project site (i.e., influence area). These sources include rail lines, freeways or 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 sources at the MEIs. Highway 116 (S.R. 116) was identified as a potential TAC source that could affect the project MEIs. No existing stationary sources were identified within the influence area. In addition, there is one development project whose potential simultaneous construction would contribute to the cumulative risk. The risk impacts from this development are included within the analysis. Figure 2 shows the location of the sources affecting the MEIs. Health risk impacts from these sources upon the MEIs are reported in Table 6. Details of the cumulative screening and health risk calculations are included in Attachment
3. Highways – S.R.116
The project site is located near S.R. 116 (see Figure 2). Cancer risk, PM2.5 concentrations, and HI associated with traffic on S.R. 116 were estimated using BAAQMD screening values provided via GIS data files (i.e., raster files). BAAQMD raster files provide screening-level cancer risk, PM2.5 concentrations, and HI for roadways within the Bay Area and were produced using AERMOD and 20x20-meter emissions grid. The raster file uses EMFAC2021 data for vehicle emissions and fleet mix for roadways, and includes Appendix E of the Air District’s CEQA Air Quality Guidance for risk assessment assumptions. Note that these values are not adjusted for age sensitivity or exposure duration and are considered higher than values that would be obtained with refined modeling 20 methods. Screening-level cancer risk, PM2.5 concentration, and HI at the project MEIs were identified using GIS software and are listed in Table 6.
BAAQMD Permitted Stationary Sources
Permitted stationary sources of air pollution near the project site were identified using BAAQMD’s Permitted Stationary Sources 2021 GIS website,18 which identifies the location of nearby stationary sources and their estimated risk and hazard impacts, based on emissions and adjustments to account for OEHHA’s risk guidance. There were no identified sources within the project’s 1,000-foot influence area.
Figure 2. Project Site and Nearby TAC and PM2.5 Sources Construction Risk Impacts from Nearby Developments
The Cotati Village #1 is a potential project located within 1,000 feet of the proposed Project. It would include the construction of six, three-story mixed-use buildings that would consist of 177 residential units, approximately 29,415-sf of retail and office space, and 271 parking spaces. The 18 BAAQMD, Stationary Source Screening Map, 2023. Web:
https://baaqmd.maps.arcgis.com/apps/webappviewer/index.html?id=845658c19eae4594b9f4b805fb9d89a3 21 controlled construction risks and hazard values for the nearby development were available from its air quality technical report conducted by Illingworth & Rodin, Inc.Construction of this project is anticipated to be all or almost fully completed prior to construction of the proposed Project. This cumulative analysis conservatively assumed the entire construction period from the proposed project would overlap with the nearby development’s construction schedule. This approach provides an overestimate of the health risk and hazard levels because it assumes that maximum impacts from the nearby development occurs concurrently with the proposed project at the proposed project’s MEIs. The controlled construction risks reported in the applicable air quality assessments were included in Table 6.
Summary of Health Risks at the Project MEI
Table 6 reports both the project and cumulative health risk impacts at the sensitive receptors most affected by the project (i.e., the MEI). The project would have an exceedance with respect to health risk caused by project construction activities, since the maximum uncontrolled cancer risk and annual PM2.5 concentration exceed the BAAQMD single-source thresholds and the annual PM2.5 concentration exceeds the cumulative-source thresholds. With the implementation of COA AQ-1, the project’s cancer risk and PM2.5 concentration would be lowered to levels below the significance thresholds. The HI risk value, which includes uncontrolled and controlled, does not exceed the single- or cumulative source threshold.

Non-CEQA: On-Site Health Risk Assessment for TAC Sources - New Project Residences The BAAQMD CEQA Air Quality Guidelines recommend that proposed projects that include sensitive receptors address the impacts of nearby sources upon them. In addition, Cotati’s General Plan Policy CON 2.2 requires that projects minimize exposure of sensitive receptors to air pollutants and toxic air contaminants. Therefore, a health risk assessment was completed to assess the impact that the existing TAC sources would have on the new proposed sensitive receptors (i.e., residents) introduced by the project. The same TAC sources identified above were used in this 22 health risk assessment.19 BAAQMD’s recommended thresholds for health risks and hazards, shown in Table 1, are used to evaluate on-site exposure. All on-site health risk results are listed in Table 7. Attachment 3 includes the screening and risk calculations for TAC source impacts upon the proposed on-site sensitive receptors.
Highways – S.R. 116
The roadway analysis for the project residents was conducted in the same manner with the BAAQMD screening tools as described above for the off-site MEIs. Table 7 shows the health screening results from the roadway.
Stationary Sources
As mentioned above, there are no nearby stationary sources within 1,000 feet of the project site.
Construction Risk Impacts from Nearby Development
Impacts from construction of the nearby development is not included in this portion of the analysis since it is assumed that construction of the Cotati Village #1 development would be completed prior to occupation of the proposed project.
Combined Cumulative Health Risk at Project Site
Health risk impacts from the existing TAC sources upon the project site are reported in Table 7.
The risks from the TAC sources are compared against both the BAAQMD single-source threshold and the cumulative source threshold. As shown, existing sources of TAC emissions do not exceed the BAAQMD single-source or cumulative-source thresholds for cancer risk, annual PM2.5 concentration, or HI.

23 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 5,215.6 million metric tons (MMT) carbon dioxide equivalent (CO2e).20 These emissions were lower than peak levels of 7,416 MMT that were emitted in 2007. CARB updates the statewide GHG emission 20 United States Environmental Protection Agency, 2022. Draft Inventory of U.S. Greenhouse Gas Emissions and Sinks 1990-2020. February. Web: https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-andsinks 24 inventory on an annual basis where the latest inventory includes 2000 through 2020 emissions.21 In 2020, GHG emissions from statewide emitting activities were 369.2 MMT CO2e. The 2020 emissions have decreased by 25 percent since peak levels in 2004 and are 35.3 MMT CO2e lower than 2019 emissions level and almost 62 MMT CO2e below the State’s 2020 GHG limit of 431 MMT CO2e. Per capita GHG emissions in California have dropped from a 2001 peak of 13.8 MT CO2e per person to 9.3 MT CO2e per person in 2020.
Recent 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 202222. 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. 21 CARB. 2022. California Greenhouse Gas Emission for 2000 to 2020. Web:
https://ww2.arb.ca.gov/sites/default/files/classic/cc/inventory/2000-2020_ghg_inventory_trends.pdf 22 CARB. 2022. Final 2022 Scoping Plan Update and Appendices. Web: https://ww2.arb.ca.gov/ourwork/programs/ab-32-climate-change-scoping-plan/2022-scoping-plan-documents 25 The legislation also allows applicants to bypass certain environmental reviews under CEQA if they 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 organizations (e.g., ABAG and 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. A similar process is used to reduce transportation emissions of ozone precursor pollutants in the Bay Area.
Senate Bill 350 - Renewable Portfolio Standards
In September 2015, the California Legislature passed SB 350, which increases 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.
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.
23 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 a direct air capture. 23 California Air Resource Board, 2017. California’s 2017 Climate Change Scoping Plan: The Strategy for Achieving California’s 2030 Greenhouse Gas Targets. November. Web:
https://ww2.arb.ca.gov/sites/default/files/classic//cc/scopingplan/scoping_plan_2017.pdf 26 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.24 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 beginning 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.
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 transportation25. 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 2030 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. 24 https://ww2.arb.ca.gov/our-work/programs/ab-32-climate-change-scoping-plan/2022-scoping-plan-documents 25 Governor’s Office of Planning and Research. 2018. Technical Advisory on Evaluating Transportation Impacts in CEQA. December.
27 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.
Senate Bill 100 – Current Renewable Portfolio Standards 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 would require 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.
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 11.26 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 California Energy Commission (CEC). This code includes design requirements to conserve energy in new residential and non-residential developments, while being cost effective for homeowners. 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. Under the 2019 standards, single-family homes are predicted to be 53 percent more efficient than homes built under the 2016 standard due more stringent energy-efficiency standards and mandatory installation of solar photovoltaic systems. For nonresidential developments, it is predicted that these buildings will use 30 percent less energy due to lightening upgrades.27
Requirements for electric vehicle (EV) charging infrastructure are set forth in Title 24 of the California Code of Regulations. The CALGreen 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 26 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. 27 See: https://www.energy.ca.gov/sites/default/files/2020-03/Title_24_2019_Building_Standards_FAQ_ada.pdf 28 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 requirements for both EV readiness, installation of EV chargers, and include both mandatory requirements and more aggressive voluntary Tier 1 and Tier 2 provisions. 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 30 climate goals.
CEC studies have identified the most aggressive electrification scenario as putting the building sector on track to reach the carbon neutrality goal by 2045.28 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.
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, including plug-in hybrid electric vehicles. 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.
City of Cotati
The City of Cotati currently has no adopted Climate Action Plan (CAP); however, Cotati General Plan Policy CON2.8 supports the development and implementation of a CAP. The City is involved in Sonoma County’s efforts to reduce countywide emissions to 25% below 1990 emissions by 2020.29

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.30 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.
Emissions for the proposed project are discussed below. 30 Justification Report: BAAQMD CEQA Thresholds for Evaluating the Significance of Climate Impacts from Land Use Project and Plans. Web: https://www.baaqmd.gov/~/media/files/planning-and-research/ceqa/ceqa-thresholds2022/justification-report-pdf.pdf?la=en 30 CalEEMod Modeling
CalEEMod was used to predict GHG emissions from operation of the site assuming full build-out of the project. The project land use types and size and other project-specific information were input to the model, as described above within the construction period emissions. CalEEMod output is included in Attachment 1.
Construction GHG Emissions
GHG emissions associated with construction were computed at 240 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 encourages the incorporation of best management practices to reduce GHG emissions during construction where feasible and applicable.
Operational GHG Emissions
The CalEEMod model, along with the project vehicle trip generation rates, were used to estimate daily emissions associated with operation of the proposed project. As shown in Table 8 for informational purposes, annual GHG emissions resulting from operation of the proposed project are predicted to be 1,488 MT of CO2e in 2026.
Table 8. Annual Project GHG Emissions (CO2e) in Metric Tons Source Category Proposed Project in 2026
Mobile 1,427
Area 2
Energy Consumption 19
Water Usage 3
Solid Waste Generation 37
Total (MT CO2e/year) 1,488
There are no quantified thresholds for GHG emissions adopted by the City or currently used by BAAQMD for evaluation of project GHG emissions. BAAQMD in their latest adopted GHG thresholds recommend that the significance of project GHG emissions be evaluated based on consistency with an adopted GHG reduction plan or meet design elements that are critical in reducing GHG emissions. As described above, the City has not adopted a CAP but has met design elements that will reduce GHG emissions such as Title 24 and Cal Green Tier 1 compliance, all electric appliances, and the required amount of EV parking spaces.
The Project generally meets the requirements for Project thresholds identified above by BAAQMD. To avoid interference with statewide GHG reduction measures identified in CARB’s Scoping Plan and SB 100 goals, the project would include the following standard requirements:
31 1. Avoid construction of new natural gas connections for the residential buildings, Conforms – the applicant has confirmed that the project will be all electric and not include natural gas infrastructure.
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 (EV) charging infrastructure that meets current Building Code CALGreen Tier 2 compliance, and
Does Not Conform – project will provide EV parking spaces as required by Cotati Municipal Code 14.04.130, which only meets the CalGreen Tier 1 requirements for EV parking and charging infrastructure.
4. Reduce VMT per service population by 15 percent over regional average. Conforms – According to the traffic analysis,31 the project daily VMT per capita is
14.6 miles, which is lower than the significance threshold of 15.5 miles. The retail coffee shop screens out because it is considered to be local serving retail and would not increase total VMT.
COA GHG-1: Include EV parking and charging infrastructure that would meet CalGreen Tier 2 requirements.
The applicant and City shall develop a plan to include EV charging stations and infrastructure to meet the general requirements of CalGreen Tier 2, which is the threshold used by BAAQMD to judge GHG impacts from new land use projects.
Effectiveness of COA GHG-1:
With appropriate EV charging stations and infrastructure implemented, the project would meet all the GHG requirements and conform with Threshold A.
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 buildings would be constructed in conformance with CALGreen, the Title 24 Building Code, and the City’s General Plan, which requires high-efficiency water fixtures, water-efficient irrigation systems, and compliance with current energy efficacy standards. The Project would not interfere with City or State efforts to reduce GHG emissions.
Conclusions
The purpose of this report is to address air quality, health risk, and greenhouse gas (GHG) impacts associated with the construction and operation of this proposed Cotati Village #2 project. Air quality impacts from this project would be associated with the demolition/grading of the existing land uses, construction of the new building and infrastructure, and operation of the project. Air 31 Email correspondence from Heather Gurewitz, M-Group and Barry Bergman, W-Trans, May 28, 2024. 32 pollutants and GHG emissions associated with construction and operation of the project were predicted using appropriate computer models. In addition, the potential project health risk impacts (includes construction and operation) and the impact of existing toxic air contaminant (TAC) sources affecting the nearby and proposed sensitive receptors were evaluated. The analysis was conducted following guidance provided by BAAQMD. Findings of this report are as follows:
Emissions of criteria air pollutants from construction and operation of the Project were modeled to be below thresholds recommended by BAAQMD that are used to judge the significance in terms of burden to air basin-wide emissions. Construction period emissions of diesel particulate matter, which is a TAC, are above BAAQMD project-level thresholds. COA AQ-1 would reduce emissions of diesel particulate matter and dust. COA AQ-1 would reduce TAC emissions by 73 percent or more and dust emissions by 65 percent or more. This would reduce the impact to a level of lessthan-significant. Operation of the Project is not anticipated to result in substantial localized TAC emissions that would cause or contribute to significant impacts. The Project would meet three of the four GHG thresholds by not having significant VMT impacts, would be all electric, and constructed to meet current CalGreen standards that would make it energy efficient. However, the Project would only meet the City’s CalGreen Tier 1 requirements for EV parking and charging infrastructure and not CalGreen Tier 2 as required by the BAAQMD GHG threshold. COA GHG-1 would require CalGreen Tier 2 for EV parking and charging infrastructure, and then the project would meet all the GHG requirements and conform with Threshold A.

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 11.1 annual days of extreme heat Extreme Precipitation 11.6 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 9.76 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 24-049 Cotati Village #2 BMPs T4i 2026 Detailed Report, 5/23/2024 68 / 74
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 11.1 annual days of extreme heat Extreme Precipitation 11.6 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 9.76 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. 24-049 Cotati Village #2 BMPs T4i HRA Detailed Report, 5/23/2024 40 / 46
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.
