They certainly were the wealthiest and most thoughtful of all the Shoshoneans of the State, and dominated these civilizations wherever contacts occurred.
SETTLEMENT
According to Bean and Smith (1978:538), the Gabrielino are, in many ways, one of the least known groups of California’s native inhabitants. In addition to much of the Los Angeles Basin, they occupied the offshore islands of Santa Catalina, San Nicolas, and San Clemente. Gabrielino populations are difficult to reconstruct. However, at any one time, as many as 50 to 100 villages were simultaneously occupied. Like the prehistoric culture before them, the Gabrielino were a hunter/gatherer group who lived in small sedentary or semi-sedentary groups of 50 to 100 persons, termed rancherias. These rancherias were occupied by at least some of the people all of the time. Location of the encampment was determined by water availability. Houses were circular in form and constructed of sticks covered

with thatch or mats. Each village had a sweat lodge as well as a sacred enclosure (Bean and Smith 1978). Although the earliest description of the Gabrielino dates back to the Cabrillo expedition of 1542, the most important and extensive accounts were those written by Father Gerónimo Boscana about 1822 and Hugo Reid in 1852.
SUBSISTENCE
Gabrielino subsistence relied heavily on plant foods, but was supplemented with a variety of meat, especially from marine resources. Food procurement consisted of hunting and fishing by men and gathering of plant foods and shellfish by women. Hunting technology included use of the bow and arrow for deer and smaller game, throwing sticks, snares, traps, and slings. Fishing was conducted with the use of shell fishhooks, bone harpoons, and nets. Seeds were gathered with beaters and baskets.
Seeds and other foods were stored in baskets. Seeds were prepared with manos and metates and/or mortars and pestles. Food was cooked in baskets coated with asphaltum, in stone pots, on steatite frying pans, and by roasting in earthen ovens (Bean and Smith 1978).
TRADE
Most trade between settlements was through reciprocity (barter), indicated by strings of Olivella shell beads used as a medium of exchange throughout southern California (Ruby 1970). Gabrielino and Juaneño from the mainland probably traded trade beads, game, and plant foods in exchange for shell beads and steatite, and plant foods from the islanders. Steatite artifacts along with fish, shell money, and animal pelts were traded by the mainlander Gabrielino into the interior for seeds and deer skin.
According to Bean and Saubel (1972), the Gabrielino traded with the Serrano and the Cahuilla to the east. The Gabrielino traded goods such as shell beads, dried fish, sea otter pelts, asphaltum, and steatite for goods such as salt, obsidian, deer hides, furs, and acorns. There is evidence of trade between the Arizona Hohokam and the Gabrielino, probably with the Mojave people as middleman (Koerper in Mason et al. 1997). Glycymeris shell bracelets, ceramics, and blankets may have been exchanged for Pacific shells and shell beads (Koerper in Mason et al. 1997).
RELIGION
Aside from shamanistic curing rituals, principal religious activity is related to the Chinigchinich cult that emphasized correct behavior as promulgated by a mythical figure, Chinigchinich. The Chinigchinich religion developed in Gabrielino territory and spread southeast to the Juaneño/Luiseño, Cupeño, and Ipai. It is a cult that is tied into an older creation myth. Chinigchinich is said to give laws and punishment for those who are disobedient in which shamans were given responsibilities to oversee the cult. It was an extensive system of polar opposites (duality) that are united under higher principals (unity) (Applegate 1979). Male-Female dualism found in the creation myth is also present in the origin myth (Applegate 1979). Chinigchinich cult ceremonies included boys’ puberty ceremonies using toloache, a drug made from Jimson Weed (Datura stramonium). During the vision quest, a personal protector or totemic animal was acquired. Such totems could be bear, coyote, crow, or rattlesnake. Other ceremonies were to obtain vengeance on enemies; to express thanks for victory; and to commemorate the dead. The focus of the ceremonies was a circular sacred enclosure found in each village. The emphasis on male rites of passage and war may be a response to the increasing population and resultant competition for territory and access to resources. Or it may be a response to the arrival of the Spanish since the Chinigchinich religion seems to be of recent (not prehistoric) origin.

Both inhumation (burial in a grave) and cremation were practiced. During cremations, the goods of the deceased and his hut were often buried with him. Annual mourning ceremonies were held in the late summer for all who had died during the previous year. Clothes of the deceased and an image of the deceased were often burned at this time. Eagles were sacrificed for recently deceased chiefs (Applegate 1979).
SACRED LANDS RECORD SEARCH
On January 5, 2022, VCS contacted the Native American Heritage Commission (NAHC) to request a Sacred Lands File (SLF) search and to obtain an AB 52 tribal contacts list. The NAHC had not yet responded as of February 2, 2022. The City of San Jacinto, however, has its AB 52 tribal contacts list to be used in consultation. The NAHC advises that notification letters to tribes should include the results of a records search, pedestrian survey, and SLF search. Ethnographic and geotechnical studies should also be provided. The City of San Jacinto conducted this consultation as described above.
PROJECT IMPACTS
a) Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:
1) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)?
Less Than Significant Impact With Mitigation Incorporated: The Project Footprint is not listed or eligible for listing in the California Register of Historical Resources or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k). The record search conducted for the Project site identified one resource (P-33-021063) was recorded within the Project site and was previously removed from the property. This previously removed site was associated with the Devoe/Bandick Ranch Complex that was constructed sometime before 1966, and is not associated with a tribal cultural resource. Additionally, cultural resources have been identified within one mile of the Project site, which included mostly built environment resources, including, one large basin metate (33-14710)—a prehistoric milling tool—was discovered approximately 1.5 meters below the surface in a utility trench approximately 1,000 feet southwest of the Project site. This attests to the presence of prehistoric populations in the area. Because historical resources are known to occur within the region, there is the potential that unknown historical resources could be encountered during excavation activities. It is recommended that archaeological monitoring and Native American monitoring occur during Project excavations into younger Holocene alluvial soils, estimated to occur within near surface soils to a depth of five (5) to ten (10) feet. With implementation of Mitigation Measure CR-1 potential impacts to unknown cultural resources would be less than significant.
Mitigation Measures: Mitigation Measure CR-1 is required.

In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.
Less Than Significant Impact With Mitigation Incorporated: Implementation of the proposed Project would not cause a substantial adverse change to a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.

The Project site is currently undeveloped without any onsite utility systems. The Project would be required to extend 8-inch public water facilities within the Project site to serve all the proposed lots with two points of connection (POC) to Eastern Municipal Water District’s (EMWD) existing water system: POC-1 located at Estrella Street and Marilyn Drive, and POC-2 located at Appaloosa Drive and Lyon Avenue. An existing 8-inch sewer line is located along Lyon Avenue. The existing water and sewer lines would also be extended into the Project site and routed around the onsite roadways. Additionally, existing communication systems in the Project vicinity would be extended into the Project site. New storm drain facilities would be constructed, including a segment of the San Jacinto Valley Master Drainage Plan storm drain system Line G-3. Construction of new utilities and connections to offsite utility systems would involve some minor trenching. Potential impacts would be short-term and construction BMPs would be in place to minimize construction related impacts. Each utility service provider would coordinate on the design/installation and would review for compliance with utility systems construction standards. Coordination with utility providers and compliance with utility standards would reduce potential impacts to less than significant.
Mitigation Measures: No mitigation measures are required. b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? Less Than Significant Impact: The proposed Project would have sufficient water supplies available to serve the Project and the reasonably foreseeable future during normal, dry, and multiple dry years.
The Eastern Municipal Water District (EMWD) would provide water service to the Project. EMWD provides potable water and recycled water to an area of approximately 555 square miles in western Riverside County. The service area includes seven (7) incorporated cities in addition to unincorporated areas of Riverside County, including the City of San Jacinto. EMWD has a diverse portfolio of local and imported supplies. Local water supplies include recycled water, potable groundwater, and desalinated groundwater. EMWD uses 100 percent of its recycled water to irrigate landscape and agricultural fields and provide water for industrial customers. Additionally, EMWD has groundwater wells in two groundwater management areas to supplement their local water supplies. EMWD also receives imported water from the Metropolitan Water District of Southern California (Metropolitan). About half of the water used in EMWD’s service area is imported by Metropolitan.
The proposed Project consists of 181 lots which are estimated to generate an Average Day Demand of 79,640 gallons per day and a Maximum Day Demand of 159,280 gallons per day (EMWD 2022). The Project would be required to extend 8-inch public water facilities in-tract to serve all the proposed lots with two points of connection (POC) to EMWD’s existing water system: POC-1 located at Estrella Street and Marilyn Drive, and POC-2 located at Appaloosa Drive and Lyon Avenue.
Water Agencies, such as the EMWD, are required to prepare and update their Urban Water Management Plans (UWMP) every five (5) years. The UWMP identifies long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs. The UWMP includes a water supply and demand assessment that compares the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting multiple consecutive water years. The most recent UWMP for EMWD was prepared in 2021. Below is a comparison between the supply and demand within the service area for projected years between 2025 and 2045 under a normal water year, single dry year, and multiple dry years; refer to Table 4.19-2,

Project implementation would increase water demand over the current condition. The water supply and water demand provided in the UWMP is based on local growth projections provided in the City of San Jacinto General Plan. The proposed Project would be consistent with the City of Jacinto General Plan. Therefore, the water demands for the Project would be accounted for in the 2025-2044 UWMP.
The UWMP identifies that there would be increased water supplies to account for future growth within the EMWD service area and that there would be adequate water supplies for normal, single dry, and multiple dry years. EMWD has indicated through coordination on the Project, that they would have sufficient water supplies available to serve the Project from existing entitlement and resources and no new or expanded entitlement would be needed (EMWD 2022).
The final water plan design for the Project would be required to comply with the EMWD New Development Process, which would involve due diligence conditions, review of design and plan check review. Additionally, water improvements would be required to comply with EMWD Engineering Standards and Specifications to ensure water efficient facilities and water conservation measures are incorporated into the Project. The proposed Project would be required to coordinate with EMWD and secure a Will Serve Letter which would indicate that EMWD would have the ability to provide adequate water service to the proposed Project. With coordination and compliance with the EMWD New Development Process and based on Project-specific input received from EMWD, long-term operational impacts associated with providing water services to the Project would be less than significant.
Mitigation Measures: No mitigation measures are required. c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? Less Than Significant Impact: Project implementation would increase demand for wastewater service. Sanitary sewer service for the Project would be provided by the City of San Jacinto. The City’s wastewater collection system consists of approximately 178 miles of main sewer lines, ranging in size from 6” to 18”. Access to the collection is provided with 2,772 manhole locations. Currently, there is an existing sewer line along Lyon Avenue. The City indicated through coordination on the Project that the existing sewer line along Lyon Avenue would have available capacity (City of San Jacinto 2022). The Project would extend the sewer line onto the Project site to provide sewer collection service for the proposed residential homes. Additionally, as part of the final design, the Project would be required to coordinate with the City and secure a Will Serve Letter, which would ensure that the City would have the ability to provide adequate wastewater service. Based on coordination with the City, long-term operational impacts associated with providing wastewater service to the Project would be less than significant.
Eastern Municipal Water District (EMWD) provides wastewater services to approximately 239,000 customers within its service area and currently treats approximately 43 million gallons per day (MGD) of wastewater at four (4) active regional water reclamation facilities. Wastewater treatment for the proposed Project would be treated at the San Jacinto Valley Regional Water Reclamation Facility (SJVRWRF). In 2015, the SJVRWRF was increased to a maximum capacity of 14 million gallons per day (EMWD 2021). The expansion of the SJVRWRF allowed EMWD to receive wastewater from throughout the San Jacinto Valley and, through a mostly biological process, transform it into tertiary level recycled water. That recycled water is pumped through a separate distribution system and delivered to the region for non-potable reuse. Those uses include water for irrigation on crops, golf courses, school

fields, parks, and landscape medians. The plant currently treats seven (7) million gallons per day (EMWD 2021), indicating that there would be available capacity well into the future.
The expansion of SJVRWRF was based on future growth projections in the San Jacinto Valley provided by local cities and the County of Riverside. The growth projections for the City and associated wastewater demands for the Project would be accounted for as part of the design of the expansion plans for the SJVRWRF. In addition, the total amount of projected wastewater flow to EMWD’s SJVRWRF for the year 2040 would be approximately 16.4 MGD, pursuant to the General Plan Draft EIR (City of San Jacinto, July 2022). The current capacity for the SJVRWRF is 14 MGD and the maximum capacity for the SJVRWRF is 27 MGD. Therefore, the ultimate capacity of the SJVRWRF would be able to meet the projected wastewater production from the City of San Jacinto (City of San Jacinto, July 2022), including the Project. The increase in wastewater treatment generated by the Project would have a less than significant impact.
Mitigation Measures: No mitigation measures are required. d) Generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals?
Less Than Significant Impact: The proposed Project would not generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals. Project implementation would increase the demand for solid waste disposal over the current condition. Pursuant to correspondence with the City of San Jacinto (2021), each house in the Project’s new development would generate an average of 81.45 pounds of solid waste per day (Municipal Solid Waste 47.4 lbs./house, Recycle 21.25 lbs/house, Organics 12.8 lbs./house). The Project on a whole would generate approximately 7.4 tons of solid waste per day. Solid waste disposal for the Project would be provided by CRR, including solid waste, recyclables, green waste, food waste, construction and demolition waste and electronic waste. CRR would collect the solid waste and transport it to the Lamb Canyon Landfill or El Sobrante Landfill. The Lamb Canyon and El Sobrante Landfills are permitted to receive 5,000 tons of solid waste per day and 16,054 tons of solid waste per day, respectively (CalRecycle 2015; 2018). The Lamb Canyon Landfill has a maximum permitted capacity of 39,681,513 cubic yards with a remaining capacity of 19,242,950 cubic yards as of 2015 (CalRecycle 2015). The El Sobrante Landfill has a maximum permitted capacity of 209,910,000 cubic yards with a remaining capacity of 143,977,170 cubic yards as of 2018 (CalRecycle 2018). The 7.4 tons of solid waste generated daily from the Project would be well below the daily amount of solid waste disposal permitted by the Lamb Canyon and El Sobrante Landfills. The amount of solid waste generated during Project construction would not exceed the capacity of local facilities or exceed state or local standards. Potential impacts associated with providing solid waste disposal service to the proposed Project would be less than significant.
Mitigation Measures: No mitigation measures are required. e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
Less Than Significant Impact: Project implementation would comply with federal, state, and local management and reduction statutes and regulations related to solid waste. The Project would produce solid waste associated with the construction stages as well as during operation. The Project would be

required to comply with state and local statutes and regulations related to solid waste handling and disposal. Applicable regulations include California’s Integrated Waste Management Act of 1989 (AB 939), which required cities and counties throughout the state to divert 50% of all solid waste from landfills through source reduction, recycling, and composting; 2008 modifications of AB 939 to reflect a per-capita requirement rather than tonnage; AB 341, which increased the statewide goal for waste diversion to 75 percent by 2020; and the California Solid Waste Reuse and Recycling Access Act (AB 1327), which requires local agencies to adopt an ordinance to set aside areas for collecting and loading recyclable materials in development projects.
In accordance with the California Department of Resources Recycling and Recovery disposal requirements, Best Management Practices (BMPs) would be employed to reduce solid waste disposal such as the recycling of all plastic bags, containers, and green waste composting, chipping, and shredding. Additionally, BMPs would be implemented to reduce the solid waste generated from construction activities, and where feasible, would recycle construction debris. With implementation of BMPs and compliance with the California Department of Resources Recycling and Recovery disposal requirements, potential solid waste disposal impacts would be less than significant. Project implementation would not conflict with the ability to comply with these regulations.
Mitigation Measures: No mitigation measures are required.

ENVIRONMENTAL ANALYSIS
A wildland fire is a non-structural fire that occurs in vegetative fuels. Wildland fires can occur in undeveloped areas and spread to urban areas where the landscape and structures are not designed and maintained to be ignition resistant. The potential for wildland fires represents a hazard where development is adjacent to open space or within proximity to wildland fuels or designated Fire Hazard Safety Zones. According to the California Department of Forestry and Fire Protection’s (CAL FIRE) Fire Hazard and Severity Zones Viewer, the Project site is not within or near a Very High, High or Moderate Fire Hazard Zone and would not be subject to wildland fire impacts. The nearest such designated areas are over 2.5 miles away to the east (CAL FIRE 2007).
a) Substantially impair an adopted emergency response plan or emergency evacuation plan?
No Impact: Project implementation would not substantially impair an adopted emergency response plan or emergency evacuation plan. According to the California Department of Forest and Fire Protection, the Project site is not identified as a High Fire Hazard Area or near a State Responsibility Area (CAL FIRE 2007). The Riverside County Sheriff’s Department in conjunction with the Riverside County Fire Department would be in charge of evacuating neighborhoods in the event of a fire that threatens homes. These evacuations would be decided within the Incident Command Structure in consultation with the fire department, law enforcement, public works, and local government liaisons in order to establish when and where they would occur. In the event of emergency, residents would be directed to specific evacuation routes with specific emergency response plans. With compliance with Incident Command Structure emergency plans and procedures, the Project would not substantially

impair an adopted emergency response plan or emergency evacuation plan. There would be no impacts related to emergency response or emergency evacuation plans.
Mitigation Measures: No mitigation measures are required. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
No Impact: The Project would not exacerbate wildfire risks due to slope, prevailing winds, and other factors, and thereby expose Project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire. Topography influences the movement of air and the direction of a fire course. Additionally, wind events magnify the risks of wildfire and would have the potential to expose inhabitants to elevated pollutant concentrations. According to the California Department of Forestry and Fire Protection, the Project site is not identified as a High Fire Hazard Area or near a State Responsibility Area (CAL FIRE 2007). Additionally, the Project site is relatively flat and not contiguous with wildland slope areas that could act as a conduit for wildland fire. The Project would also have surrounding roadways and driveways, which would act as fire breaksshould a fire occur within or near the Project site. Therefore, the Project would not exacerbate wildfire risks and there would be no impacts.
Mitigation Measures: No mitigation measures are required. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?
No Impact: The proposed Project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment.
As previously discussed, the Project site is not identified as a High Fire Hazard Area or near a State Responsibility Area (CAL FIRE 2007). The Project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) located in a high fire hazard or wildland interface area; the Project site is located within a flat suburbanized area of the City. In addition, the Project includes the construction of water infrastructure and other utility improvements that would aid in fire suppression. No impacts are anticipated.
Mitigation Measures: No mitigation measures are required. d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes?
No Impact: Project implementation would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. Landslides, including mud flows and debris flows can be triggered by erosion and downslope runoff caused by rain following a fire. As previously discussed, the Project site

is not identified as a High Fire Hazard Area or near a State Responsibility Area (CAL FIRE 2007). The Project site is also not within a flood hazard area or landslide hazard area that would be subject to mud flows. The Project vicinity is relatively flat and not immediately upstream of notably sloped or hillside areas. No impacts are anticipated.

ENVIRONMENTAL ANALYSIS
a) Have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?
Less Than Significant Impact With Mitigation Incorporated: A biological evaluation of the Project identified that the Project footprint does not support any sensitive vegetation communities.
Portions of the Project footprint area contain Traver soil series, which is a soil series known to have the potential to support sensitive plant species. The initial biological survey and desktop review indicated a moderate potential for the smooth tarplant (CRPR 1B.1) and San Diego tarplant (CRPR 4.2) to occur. The initial biological survey and desktop review also indicated low-moderate potential for the chaparral sand verbena (BLM, USFS sensitive species, CRPR 1B.1); Parish’s brittlescale (USFS sensitive species, CRPR 1B.1); Davidson’s saltscale (CRPR 1B.2); vernal barley (CRPR 3.2); Coulter’s goldfields (BLM sensitive species, CRPR 1B.1); and salt spring checkerbloom (USFS sensitive species, CRPR 2B.2)

Final | July 2023 4.21-2 Mandatory Findings of Significance to occur. A focused rare plant survey was then conducted at the Project on April 20, 2022 to verify or rule-out the presence of these species. The focused rare plant survey produced negative results; and therefore, the moderate and low-moderate potential for occurrences were reduced to low potential.
Based on lack of suitable habitat onsite and negative findings during the April 2022 focused rare plant survey, special status plant species are not anticipated to occur within the Project footprint. No impacts to special status plants are anticipated because of Project implementation and no mitigation is required.
No special status wildlife was observed on the Project site. The Project footprint does support habitat that could provide the potential for some foraging, nesting, and roosting activities. Sensitive wildlife species with moderate potential to occur on the site include ferruginous hawk (CDFW Watch List species, USFWS Bird of Conservation Concern); grasshopper sparrow (CDFW Species of Special Concern); loggerhead shrike (CDFW Species of Special Concern); USFWS Bird of Conservation Concern); western yellow bat (CDFW Species of Special Concern, Western Bat Working Group (WBWG) High Priority species); and western red bat (CDFW Species of Special Concern, WBWG High Priority species). Implementation of the Project would result in the permanent loss of approximately 35.06 acres of foraging habitat for these species. The loss of potential foraging habitat would not decrease populations below self-sustaining levels given the availability of foraging habitat remaining in the region. Therefore, permanent impacts would be less than significant. During temporary construction activities, individuals would be expected to move to adjacent habitat; therefore, there would be no direct mortality on these species. To avoid potential impacts to avian and bat species during the nesting/maternity season, Mitigation Measure BIO-1 (nesting birds) and Mitigation Measure BIO-2 (roosting bats) would require preconstruction surveys and additional avoidance should one or more of these species be detected. Implementation of these mitigation measures would reduce potential impacts to less than significant.
Additionally, the burrowing owl (CDFW Species of Special Concern, USFWS Bird of Conservation Concern) has been identified to have moderate potential to occur within the Project footprint area.
Temporary construction activities could impact burrowing owl if they were to occupy an active work area during Project construction. To avoid potential impacts to burrowing owl, Mitigation Measure BIO-3 would be implemented, which requires preconstruction surveys and additional avoidance should a burrowing owl be detected. With implementation of Mitigation Measure BIO-3, potential impacts to burrowing owl would be less than significant.
The Project footprint does not contain any drainages or riparian/riverine resources. Therefore, no state, federal or Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) jurisdictional drainages occur onsite. Further, no wetlands or vernal pools are present on the site.
The Project footprint may serve a function in local wildlife dispersal and foraging; however, due to the disturbed nature of the site and the degraded habitats, the loss of foraging habitat and/or effect on local wildlife movement would be less than significant. The Project construction activities could result in impacts to nesting birds, which would be in violation of the federal Migratory Bird Treaty Act (MBTA) and the California Fish and Game Code. To avoid and minimize the chance for impacts to nesting birds, Mitigation Measures BIO-1 and BIO-3 would be implemented, which would require preconstruction surveys if work would occur during nesting season. With the implementation of Mitigation Measures BIO-1 and BIO-3, the potential for impacts to migratory birds would be less than significant.

Final | July 2023 4.21-3 Mandatory Findings of Significance The Project is located within the boundaries of the MSHCP. The Project would be consistent with the MSHCP based on the analysis and determinations made as identified in Section 4.4.f. No Determination of a Biologically Equivalent or Superior Preservation (DBESP) mitigation plan would be required. The Project would be required to pay all applicable MSHCP development impact fees. With implementation of Mitigation Measure BIO-3 and payment of impact fees, potential impacts would be less than significant.
Implementation of the Project would not substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal species.
A cultural resources record search conducted for the property did not identify known cultural resources within the Project footprint and implementation of the proposed Project would not adversely affect any known significant historical resources. However, known cultural resources have been recorded in the region and there would be potential that unknown cultural resources could occur on the Project footprint and could be encountered during excavation activities. To avoid impacts to unknown cultural resources that could be present on the Project footprint, the Project would be required to comply with Mitigation Measure CR-1, which would require an archaeologist observe grading activities, salvage, and catalogue archaeological resources as necessary, and establish procedures for archaeological resources surveillance as well as procedures for temporarily halting or redirecting work. Additionally, Mitigation Measure CR-1 would reduce potential impacts to tribal cultural resources by requiring a Native American monitor, in the unlikely event that unknown human remains are encountered during construction.
A paleontological records search conducted for the Project footprint determined there are no documented fossil localities on the site or within a one (1)-mile radius, but numerous vertebrate fossil localities of the Diamond Valley Lake Project are within a 3 (three)-mile radius of the Project. The Project footprint contains Holocene alluvial deposits, which contain high paleontological sensitivity.
These deposits consist of alluvial sands and gravels. Many of the Diamond Valley Lake Project localities were also mapped as Holocene alluvial deposits. Based on the presence of Holocene alluvial deposits and the paleontological resources that have been recorded in the region, potential unknown paleontological resources could be encountered during excavation activities. The Project would implement Mitigation Measure PALEO-1, to require a paleontologist observe grading activities, salvage, and catalogue fossils as necessary, and establish procedures for paleontological resource surveillance as well as procedures for temporarily halting or redirecting work. With implementation of Mitigation Measures CR-1 and PALEO-1, potential impacts to unknown cultural resources and paleontological resources would be less than significant. b) Have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? Less Than Significant Impact With Mitigation Incorporated: A cumulative impact may be significant if a project’s incremental effect, though individually limited, is cumulatively considerable.
Cumulatively considerable means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, the effects of other current projects and

The analysis provided in Section 4.0, Environmental Analysis, identifies that no impacts would occur to agriculture and forestry resources, mineral resources, or wildland fire. Therefore, the proposed Project would not contribute considerably to cumulative impacts to these environmental resource issues.
Impacts related to aesthetics, light and glare, air quality construction emissions, cultural resources, energy, geology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, noise, tribal cultural resources, population and housing, public services, recreation, utilities, and service systems were determined to be less than significant or potentially significant and would require mitigation measures to reduce impacts to a less than significant level. Therefore, the Project could potentially contribute to significant cumulative impacts in these environmental issue areas. These environmental issue areas are discussed in further detail below.
AESTHETICS
As identified in Section 4.1, Aesthetics, the Project would not obstruct or modify any existing vistas and would not impact any aesthetic resources along a State Scenic Highway. The Project would be required by City Ordinance to direct light downward within the property to minimize spill over impacts onto adjacent properties. The Project would have less than significant impacts on scenic vistas and less than significant light and glare impacts. Additionally, the Project would be subject to site plan and design review for aesthetic compatibility with surrounding areas and consistency with General Plan Goals and policies that address the scenic quality. Therefore, the Project would not contribute considerably to significant cumulative impacts. Related cumulative development projects identified in Table 4.21-1 would be evaluated on a project-by-project basis for potential aesthetic impacts and would also be required to comply with applicable General Plan Policies and Goals and Zoning Code site development and design standards to minimize potential aesthetic impacts. Compliance with applicable site

Final | July 2023 4.21-5 Mandatory Findings of Significance development and design standards would reduce the potential for significant aesthetic impacts.
Therefore, the Project, when considered with the related development projects, would not result in significant cumulative impacts to aesthetic resources.
AIR QUALITY
Operational Impacts
For operational air quality emissions, any project that does not exceed or can be mitigated to less than the daily regional threshold values would not be considered by SCAQMD to be a substantial source of air pollution and would not add significantly to a cumulative impact. As identified in Section 4.3, Air Quality, Project operation would not result in emissions that exceed the SCAQMD regional emissions thresholds. Therefore, the proposed Project would not result in a cumulatively considerable net increase of any criteria pollutant or significantly contribute to cumulative air quality impacts.
Construction Impacts
The context for assessing cumulative air impacts from short-term construction activities includes quantifying emissions and comparing the emissions to the applicable SCAQMD screening thresholds.
As discussed in Section 4.3, Air Quality, the proposed Project’s construction emissions would be below SCAQMD thresholds. Further, the Project would be required to comply with SCAQMD Fugitive Dust Rule 403 and Mitigation Measure AQ-1, which requires the contractor to apply water to soils being actively disturbed during site preparation and grading activities occurring within 25 meters of the nearest residence and Monte Vista Middle School. Compliance with Rule 403 and Mitigation Measure AQ-1 would reduce PM10 and PM2.5 impacts to prevent fugitive dust from creating a nuisance offsite.
With compliance with Fugitive Dust Rule 403 and Mitigation Measure AQ-1, short-term construction air emissions would be less than significant. Therefore, the proposed Project would not contribute considerably to a net increase of any criteria pollutant. Cumulative development projects identified in Table 4.21-1 would also be required to reduce their emissions per SCAQMD rules and mandates.
Therefore, it can be reasonably inferred that Project construction activities, in combination with those from other projects in the area, would not deteriorate the local air quality and would not result in cumulatively significant construction-related air quality impacts. Additionally, construction source emissions for the Project would not exceed the applicable LSTs. Therefore, the Project’s localized emissions impacts would not contribute considerably toward exposing sensitive receptors to substantial pollutant concentrations.
Air Quality Management Plan (AQMP)
The Project would be subject to the 2016 AQMP. The Project’s construction and operational air emissions would not exceed the SCAQMD regional thresholds, and localized emissions during construction would be below SCAQMD LST thresholds. The Project would also be required to comply with the applicable SCAQMD emission reduction measures to further reduce fugitive dust emissions.
As such, the Project would not have a cumulatively considerable contribution to impacts in this regard, and a less than significant impact would occur.
BIOLOGICAL RESOURCES
The Project site does not support any sensitive vegetation communities. Therefore, the Project would not be contributing to the cumulative loss of sensitive vegetation communities. A focused rare plant survey was conducted at the Project on April 20, 2022 to verify or rule-out the presence of rare plants

Final | July 2023 4.21-6 Mandatory Findings of Significance potentially supported by onsite soil types. The focused rare plant survey produced negative results.
Based on lack of suitable habitat onsite and negative findings during the April 2022 focused rare plant survey, special status plant species are not anticipated to occur within the Project footprint. No impacts to special status plants are anticipated because of Project implementation and no mitigation is required.
The Project footprint contains suitable foraging habitat to support sensitive wildlife species and there would be moderate potential for sensitive wildlife species to occur. Sensitive wildlife species with moderate potential to occur on the site include ferruginous hawk (CDFW Watch List species, USFWS Bird of Conservation Concern); grasshopper sparrow (CDFW Species of Special Concern); loggerhead shrike (CDFW Species of Special Concern); USFWS Bird of Conservation Concern); western yellow bat (CDFW Species of Special Concern, Western Bat Working Group (WBWG) High Priority species); and western red bat (CDFW Species of Special Concern, WBWG High Priority species). Implementation of the Project would result in the permanent loss of approximately 35.06 acres of foraging habitat for these species. The loss of potential foraging habitat would not be considered a significant impact because of the existing availability of foraging habitat remaining in the region. Therefore, the Project would not contribute considerably to significant cumulative impacts associated with the loss of foraging habitat. To avoid potential impacts to avian and bat species during the nesting/maternity season, the Project would implement Mitigation Measures BIO-1, BIO-2, and BIO-3, which would require preconstruction surveys and additional avoidance should one or more of these species be detected. Implementation of these mitigation measures would reduce potential impacts to less than significant. With implementation of the mitigation measures, the Project would not contribute considerably to significant cumulative impacts to nesting birds and bat species.
There are no jurisdictional waters on the Project site. Therefore, no direct impacts to jurisdictional waters would occur and the proposed Project would not contribute to the loss of jurisdictional waters.
Related cumulative development projects identified in Table 4.21-1 would be evaluated for potential impacts to sensitive vegetation communities, sensitive plants, sensitive wildlife, impacts to jurisdictional waters, impacts to wildlife movement and potential conflicts with programs and policies that provide for the protection of biological resources. Related cumulative development projects would be required to comply with state and federal laws that provide for the protection of biological resources and where needed, would need to implement measures to minimize impacts or compensate for impacts to biological resources. Compliance with local, state, and federal laws would minimize cumulative impacts to biological resources. The proposed Project would result in less than significant impacts to biological resources. Therefore, the proposed Project, considered with the related projects, would not result in significant cumulative impacts to biological resources.
CULTURAL/PALEONTOLOGICAL RESOURCES
The context for assessing cumulative impacts to local archaeological and paleontological resources is to determine whether the Project would result in a loss of these resources that could diminish or eliminate important information relevant to the history of the Project area. The Project footprint has the potential to contain unknown archaeological resources and paleontological resources. The proposed Project would be required to comply with Mitigation Measures CR-1 and PALEO-1, which would require an archaeologist/paleontologist to evaluate any discovered potential archaeological/ paleontological resources, and implement appropriate steps to preserve or curate the artifact and halt or redirect work. This would eliminate any potential loss of important archaeological or paleontological

Final | July 2023 4.21-7 Mandatory Findings of Significance information that may be buried under the Project footprint. Therefore, the proposed Project would not contribute considerably to cumulative significant impacts related to the loss of important archaeological or paleontological resources, and/or disturbed human remains.
Related cumulative projects in the Project area would be evaluated for potential impacts to archaeological resources and paleontological resources and would be required to implement measures to reduce impacts to known and unknown archaeological resources and paleontological resources. Therefore, the proposed Project, considered with the related cumulative projects, would not result in significant cumulative impacts to cultural or paleontological resources.
ENERGY
The areas considered for cumulative impacts to electricity and natural gas supplies are the service areas of Southern California Gas Company and Southern California Edison. Implementation of the proposed Project would increase the demands for electricity and natural gas. The proposed Project and related development projects identified in Table 4.21-1 are within the Southern California Gas Company and Southern California Edison coverage areas and would be required to comply with the Building Energy Efficiency Standards and CALGreen, which would minimize wasteful energy consumption. Therefore, the proposed Project, when considered with the related cumulative development projects, would not result in significant energy consumption impacts.
GEOLOGY AND SOILS
According to the General Plan Draft EIR, the City of San Jacinto is in a region with active seismic faults.
The Project site is crossed by two (2) significant active faults that are zoned by the State Alquist-Priolo Earthquake Fault Zoning, the Claremont Fault and Casa Loma Fault, and the Project would have the potential for ground rupture impacts, Additionally, like other areas in southern California, the proposed Project could be subject to seismic shaking impacts from active faults in the region. The Project would implement Mitigation Measure GEO-1, which requires prior to issuance of a building permit and certificate of occupancy, the Applicant and City shall verify that no habitable structures are proposed or constructed within the restricted use zone (RUZ) as currently delineated or as adjusted by a licensed geotechnical engineer. Mitigation Measure GEO-2 would also require the City of San Jacinto to confirm that grading and construction plans for the Project adequately incorporate the design recommendations detailed in the Project’s Geotechnical Report. Together, Mitigation Measures GEO-1 and GEO-2 would reduce potential ground rupture and seismic shaking impacts to less than significant, and the Project would not contribute considerably to ground rupture and seismic shaking risks in the Project area.
The land clearing and grading activities associated with the proposed Project would uncover soil, which could be subject to erosion impacts caused by water and wind. Additionally, construction equipment and vehicles could indirectly transport sediment to offsite locations. Compliance with applicable NPDES erosion control requirements would reduce impacts related to substantial soil erosion or the loss of topsoil to a less than significant level. With compliance with applicable NPDES erosion control requirements, potential erosion impacts would be less than significant, and the proposed Project would not contribute considerably to cumulatively significant erosion impacts.
Related cumulative projects identified in Table 4.21-1 would be required to comply with California Building Code requirements to minimize potential ground rupture and seismic impacts and would be required to implement erosion control plans to minimize potential erosion and sedimentation impacts.

Final | July 2023 4.21-8 Mandatory Findings of Significance Therefore, the proposed Project, when considered with the related development projects, would not result in significant cumulative geologic impacts.
GREENHOUSE GAS EMISSIONS
Project-related GHG emissions are not confined to a particular air basin but are dispersed worldwide.
Therefore, the Project’s greenhouse gas emissions are assessed as a cumulative contribution to GHG impacts. As identified in Section 4.8, Greenhouse Gas Emissions, Project implementation would not exceed the GHG emissions significance threshold of 3,000 MTCO2e/yr. Therefore, Project related GHG emissions and their contribution to global climate change would not be cumulatively considerable, and GHG emissions impacts would be less than significant.
Related cumulative projects identified in Table 4.21-1 would also be evaluated for greenhouse gas emission impacts. As stated above, GHG impacts are recognized as exclusively cumulative impacts, and there are no non-cumulative GHG emission impacts from a climate change perspective. The analysis above concludes that the Project would not exceed the GHG emissions significance threshold of 3,000 MTCO2e/yr and would not interfere with the goals of SB 32. Thus, the Project’s cumulative contribution to GHG impacts would be less than significant.
HAZARDS AND HAZARDOUS MATERIALS
The Project would involve the use of incidental amounts of hazardous substances, such as fuel, oil, and solvents. To ensure hazardous substances are not inadvertently released into the environment, the Project would be required to comply with local, state, and federal laws regarding the handling, storage and transporting of hazardous substances and would be required to implement spill prevention and clean-up BMPs during construction. With compliance with local, state, and federal laws and implementation of BMPs, the potential handling of hazardous materials would be less than significant.
Therefore, the Project would not contribute considerably to cumulative impacts with regard to the release of hazardous materials into the environment.
According to the Phase I Environmental Site Assessments (Appendices F1 and F2), no evidence of a REC was identified on the Project site except for the potential presence of pesticides in shallow soils associated with historic agricultural use of the site. The results of the Phase II Site Assessment determined that contamination at the Project site was below detectible levels for pesticides and at low, background levels for metals that did not exceed the applicable Screening Levels developed by the USEPA. Potential impacts are considered less than significant. Therefore, the proposed Project would not contribute considerably to cumulative impacts with regard to creating a significant hazard to the public or the environment.
The Project was determined to have a less than significant impact to interfering with an emergency evacuation plan. The Project would not contribute considerably to conflicts with adopted emergency response plans or emergency evacuation plans.
Related cumulative development projects identified in Table 4.21-1 would be evaluated for potential hazards and potential release of hazardous substances into the environment. The related projects would also be required to comply with local, state, and federal laws and regulations regarding the handling, storage and transporting of hazardous materials. Compliance with local, state, and federal laws would reduce the potential impacts to less than significant. Therefore, the Project, considered with the related projects, would not result in significant cumulative hazards or hazardous material

Additionally, cumulative projects identified in Table 4.21-1 would be analyzed for impairment of emergency access on a project-by-project basis and would be required to comply with all roadway design standards to ensure adequate emergency access is not impacted. Therefore, the Project, when considered with the related projects, would not result in significant cumulative impacts with adopted emergency response plans or emergency evacuation plans.
HYDROLOGY AND WATER QUALITY
Project implementation would introduce impervious surfaces onto the Project site, which could increase surface water runoff rates. The Project would be required to comply with City of San Jacinto NPDES MS4 Storm Water Permit requirements and prepare and implement a Project site water quality management plan to capture and treat surface water generated from the site, which would reduce potential water impacts to less than significant. The Project would not contribute considerably to cumulatively significant water quality impacts.
The Project site is currently vacant and 100% impervious. Project implementation would result in an increase in impervious area over the current condition, which would increase the rate of surface water generated from the site. As part of the proposed improvements, a new storm drain system would be constructed to route flows around and through the Project site to two onsite detention basins, which would avoid onsite and offsite flooding. The Project would not contribute considerably to cumulative flood impacts.
Project construction activities could have the potential to generate degraded surface water impacts, which could adversely affect downstream receiving water bodies. The Project would be required to obtain a State General Construction Permit and implementation of a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP would identify Best Management Practices (BMPs) to minimize degraded surface water runoff impacts. With the implementation of Mitigation Measure HYDRO-1, potential erosion impacts would be less than significant and the Project would not contribute considerably to a cumulatively significant construction related water quality impact.
Related cumulative development projects identified in Table 4.21-1 would also have the potential to increase existing rates of surface water runoff in the Project area. Related cumulative development projects would be required to comply with NPDES MS4 Storm Water Permit requirements and prepare and implement a Project site water quality management plan to capture and treat surface water generated from their sites. Additionally, during construction, cumulative development projects could have the potential to generate degraded surface water impacts and would be required to implement SWPPP BMPs to reduce construction-related impacts. Related cumulative development projects would be required to conduct drainage studies and provide adequate stormwater management improvements to avoid onsite and offsite flooding. Therefore, the proposed Project, when considered with the related projects, would not result in significant cumulative hydrology and water quality impacts.
LAND USE
The Project would not construct any structures or barriers that would divide existing communities.
Therefore, the Project would not contribute considerably to cumulatively significant impacts that divide existing communities. As identified in Section 4.11, Land Use, the Project would be consistent with the General Plan Low-Density Residential land use designation and the Development Code Residential zoning at the Project site with the General Plan. The Project would be consistent with the

Initial Study/Mitigated Negative Declaration
Final | July 2023 4.21-10 Mandatory Findings of Significance General Plan goals and policies. Through the City of San Jacinto Site Plan Review and Design Review processes, the City of San Jacinto would ensure that the Project is consistent with the General Plan and Development Code and would not be detrimental to the orderly growth of the City. Potential land use planning impacts would be considered less than significant, and the Project would not contribute considerably to cumulatively significant land use planning conflict impacts.
Related development projects identified in Table 4.21-1 would also be subject to site-specific planning reviews that would address consistency with adopted General Plan goals, policies, and objectives, as well as with the local development code standards. Each cumulative project would be analyzed independent of other projects, within the context of their respective land use and regulatory setting.
As part of the review process, each project would be required to demonstrate compliance with the provisions of the applicable land use designation(s). Additionally, as part of the planning reviews, related projects would be subject to CEQA environmental review. Where needed, these projects would be required to provide mitigation to reduce potential adverse impacts to the environment. Thus, the Project and cumulative development projects would not contribute considerably to cumulatively significant land use impacts.
NOISE
As identified in Section 4.13, Noise, the proposed Project’s long-term operational mobile and stationary noise impacts were determined to be less than significant. Therefore, the Project would not contribute considerably to significant cumulative noise impacts. Related cumulative projects identified in Table 4.21-1 would be required to comply with applicable noise and vibration standards, and regulations to minimize noise and vibration impacts. Therefore, the proposed Project, when considered with the related cumulative projects, would not result in significant cumulative noise impacts.
Cumulatively significant construction vibration would occur when construction activities at a site occur in close proximity of one another in a way that concentrates the vibration. The further construction activities occur from one another on each respective Project site, the quicker the vibration dissipates by the time it reaches a sensitive receptor. Because heavy construction equipment moves around a Project site and would only occur for limited durations, the average vibration levels at nearby structures would diminish rapidly with increasing distance between structures. There are no ongoing or planned construction activities near the Project site that would contribute to cumulative vibration impacts. In addition, groundborne vibration generated at the site during construction would not be in exceedance of the Caltrans threshold of 0.25 inch per second peak particle velocity (PPV) and longterm vibration impacts from operations at the site would be less than significant. Therefore, the Project’s contribution to cumulative vibration impacts would not be considerable.
POPULATION AND HOUSING
As identified in Section 4.14, Housing and Population, the proposed Project would be consistent with the City of Jacinto General Plan and would not induce substantial unplanned population growth or generate a need for new housing. Development of the Project in conjunction with the related cumulative development projects identified in Table 4.21-1 would not result in cumulative citywide population and/or housing impacts in the City or the regional area. As such, the Project would not contribute to cumulatively adverse growth impacts. Related projects identified in Table 4.21-1 would be reviewed by the City, and development would be required to be consistent with adopted state and city development standards, regulations, plans, and policies to minimize the effect of the increase in

PUBLIC SERVICES
Fire Protection
The Project and related cumulative development projects identified in Table 4.21-1 would receive fire protection services from the Riverside County Fire Department. As identified in Section 4.15, Public Services, the Project would have a less than significant impact on fire protection services. The Project would be designed in compliance with the California Building Code, California Fire Code and related codes and would be reviewed by the Riverside County Fire Department to ensure it has been designed in compliance with fire protection safety requirements. The Project’s cumulative impacts to fire protection services would be less than significant and would not contribute to cumulatively considerable significant impacts. Additionally, cumulative development projects identified in Table
4.21-1 would be subject to all applicable laws, ordinances, and regulations in place for fire protection and emergency services. The Riverside County Fire Department would review all cumulative development to ensure adequate site access, fire flow, sprinkler systems, hydrant spacing, and turning radii, among other required fire protection safety criteria. The overall cumulative impacts to fire protection services would be less than significant.
Police Protection
The Project and related cumulative development projects would receive police protection services from the Riverside County Sheriff’s Department. The Project would be required to comply with all applicable laws, ordinances, and regulations in place for police protection services. As identified in Section 4.15, Public Services, the proposed Project would have a less than significant impact on law enforcement protection. The Project would not contribute considerably to cumulative impacts to law enforcement protection services. Cumulative development projects identified in Table 4.21-1 would also be evaluated for potential impacts to police services and would be required to comply with all applicable laws, ordinances, and regulations in place for law enforcement protection services.
Compliance with protection ordinances and regulations would reduce cumulative development project impacts to law enforcementservices to less than significant. Overall, cumulative impacts to law enforcement protection services would be less than significant.
School Services
The proposed Project would incrementally increase the enrollment of students in the San Jacinto Unified School District. As identified in Section 4.15, Public Services, the proposed Project would have a less than significant impact on school services. The Project would be required to pay development fees prior to issuance of a building permit to offset the cost of providing school services and facilities.
Related development projects identified in Table 4.21-1 would be evaluated for potential impacts to schools and would be required to pay development fees to fund existing and future school facilities.
With coordination with the San Jacinto Unified School District and the payment of development fees, potential cumulative impacts to school services would be less than significant.

Final | July 2023 4.21-12 Mandatory Findings of Significance
TRANSPORTATION
The traffic study prepared for the Project included both Project traffic impacts and cumulative traffic impacts from the list of related development projects in Table 4.21-1. Additionally, the traffic analysis included a 2% ambient growth to the Project area. As discussed in Section 4.17, Transportation, the Project’s long-term cumulative traffic impacts on Project roadway segments, intersections, and freeway ramps were determined to be less than significant because LOS/vehicle travel delay is no longer considered an environmental impact under the CEQA. However, Mitigation Measure T-1 would require the Project to contribute its fair share of funds to offset its contribution to vehicle delay at the intersections of Lyon Avenue/Cottonwood Avenue and Lyon Avenue/Appaloosa Drive. Therefore, the proposed Project would not contribute considerably to significant cumulative traffic or other transportation impacts. Related cumulative projects identified in Table 4.21-1 would be required to prepare traffic studies to evaluate potential traffic impacts and would have to comply with the applicable traffic design standards, regulations, and mitigation measures on a project-by-project basis to ensure significant cumulative traffic impacts do not occur. Therefore, the proposed Project, considered with the related cumulative projects, would not result in significant cumulative transportation impacts.
TRIBAL CULTURAL RESOURCES
To avoid significant impacts to unknown tribal cultural resources that could be present on the Project site, the proposed Project would be required to comply with Mitigation Measure CR-1, which requires Project monitoring by a Native American and proper consultation with Native American Tribes and the Native American Heritage Commission if subsurface tribal cultural resources are found during construction, excavation, and/or other construction activities in the area. This would eliminate any potential loss of important tribal cultural resources that may be discovered at the Project site.
Compliance with Mitigation Measure CR-1 would reduce the potential for cumulative loss of tribal cultural resources from Project construction activities to less than significant. Related cumulative development projects identified in Table 4.21-1 would also be required to comply with the provisions of AB 52, which would reduce cumulative impacts to tribal cultural resources. Therefore, the proposed Project, considered with the related cumulative projects, would not result in significant cumulative impacts to cultural tribal resources.
UTILITIES
Water
The proposed Project and related projects would increase water demand within the Project area. The Eastern Municipal Water District (EMWD) Urban Water Management Plan identifies that the service area would have adequate water supplies for normal, single dry, and multiple dry years. The final water plan design for the Project would be required to comply with EMWD Development Engineering Design Specifications for the design, and construction of EMWD service infrastructure required for new development to ensure water efficient facilities and water conservation measures are incorporated into the Project. Related projects identified in Table 4.21-1 would also be evaluated on a case-by-case basis at the project-level, as they are implemented, for their potential construction and operational impacts. All projects would be subject to the review and approval by the EMWD and would be subject to compliance with the relevant laws, ordinances, and regulations in place for water facilities. Thus,

Initial Study/Mitigated Negative Declaration
Final | July 2023 4.21-13 Mandatory Findings of Significance cumulative impacts concerning the construction of water facilities and operational demand would be less than significant.
Wastewater
Wastewater treatment for the proposed Project would be treated at the EMWD San Jacinto Valley Reclamation Plant. In 2015, the treatment plant was increased to a maximum capacity of 14 million gallons per day. The plant currently treats seven (7) million gallons per day, indicating that there would be available capacity well into the future. Potential impacts were determined to be less than significant. Additionally, as part of the final design, the proposed Project would be required to coordinate with EMWD and secure a Will Serve Letter, which would ensure that the EMWD would have the ability to provide adequate wastewater service to the proposed Project. Therefore, the Project would not contribute considerably to significant cumulative wastewater treatment capacity impacts. Related development projects identified in Table 4.21-1 would also be required to coordinate with EMWD to determine if adequate wastewater treatment capacity would be available and would be required to comply with the relevant regulations. Coordination with the EMWD and compliance with relevant laws and regulations would ensure the Project’s impacts related to the construction of wastewater facilities would not contribute considerably to cumulatively significant wastewater treatment impacts.
Solid Waste Disposal
The proposed Project and related cumulative development projects identified in Table 4.21-1 would increase demands for solid waste disposal services within the Project area. Solid waste generated by the Project would be transported to the Lamb Canyon Landfill or El Sobrante Landfill. The Lamb Canyon Landfill has a maximum permitted capacity of 39,681,513 cubic yards with a remaining capacity of 19,242,950 cubic yards as of 2015. The El Sobrante Landfill has a maximum permitted capacity of 209,910,000 cubic yards with a remaining capacity of 143,977,170 cubic yards as of 2018. The 7.4 tons of solid waste generated daily from the Project would be well below the daily amount of solid waste disposal permitted by the Lamb Canyon and El Sobrante Landfills. Potential impacts associated with providing solid waste disposal service to the proposed Project would be less than significant.
Therefore, the Project would not contribute considerably to significant cumulative solid waste disposal impacts. Related cumulative development projects identified in Table 4.21-1 would also be required to coordinate if adequate solid waste disposal service is available and would be subject to conformance with all relevant laws, ordinances, and regulations in place for solid waste disposal. This includes compliance with AB 939, which requires a 50 percent diversion of all solid waste from disposal in local landfills, and the 2016 (or most recent) California Green Building Code Standards, which includes design and construction measures that act to reduce construction-related waste through material conservation measures and other construction-related efficiency measures. With compliance with relevant laws, ordinances, and regulations in place for solid waste disposal, cumulative impacts to solid waste would be less than significant.
c) Have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?

Final | July 2023 4.21-14 Mandatory Findings of Significance beings analyzed in this Initial Study include, but are not limited to; air quality, greenhouse gas emissions, geology hazards, hazardous materials, seismic hazards, hydrology/water quality, noise and wildfire. Each issue area found that there would be either no impacts, impacts would be less than significant, or impacts would be less than significant with mitigation incorporated. The proposed Project would comply with local and regional planning programs, applicable codes, and ordinances, state and federal laws and regulations, and mitigation measures to ensure that long-term operation activities and short-term construction activities associated with the proposed Project would not result in direct, or indirect adverse impacts to human beings. d) Have the potential to achieve short-term environmental goals to the disadvantage of long-term environmental goals?
Less Than Significant Impact: The proposed Project would not have the potential to achieve shortterm environmental goals to the disadvantage of long-term environmental goals. If the proposed Project is approved and constructed, a variety of short- and long-term impacts would occur. During construction, surrounding land uses could be temporarily impacted by dust and noise. There could also be an increase in vehicle pollutant emissions caused by grading and construction activities and potential generation of degraded surface water. However, these short-term effects would be temporary and would be avoided or lessened to a large degree through implementation of mitigation measures and compliance with regulatory requirements. The Project would result in long-term environmental consequences associated with a transition in land use from vacant land to residential land uses. Long-term operation of the Project would change the physical appearance of the Project site and would contribute to increased traffic volumes, increased noise from operation of the Project, increased amounts of impervious surfaces and increased energy and natural resource consumption.
However, these long-term operational effects would be reduced to a less than significant level through implementation of mitigation measures and compliance with regulatory requirements. Construction and operation of the Project would not result in significant adverse effects to the environment.
Therefore, the Project would achieve short-term environmental goals that would not result in the disadvantage of long-term environmental goals.

AIR QUALITY
AQ-1: PM10 and PM2.5 Reduction. Contractor shall be conditioned to apply water to soils being actively disturbed during site preparation and grading activities occurring within 25 meters of the nearest residence and Monte Vista Middle School. Water shall be applied at least three (3) times daily such that the moisture content reaches 15%. Further, during site preparation specifically, equipment use shall be limited to no more than two (2) rubbertired dozers and two (2) tractors/loaders/backhoes or like equipment, working simultaneously within 25 meters of the nearest residence and Monte Vista Middle School ball field when students are present.
Additionally, contractor shall apply soil stabilizers to unpaved onsite roads; sweep adjacent offsite paved roads and limit onsite vehicle travel to 15 miles per hour to minimize tire entrainment.
BIOLOGICAL RESOURCES
BIO-1: Preconstruction Survey. To maintain compliance with the Migratory Bird Treaty Act (MBTA and California Fish and Game Code Sections 3503, 3503.5, and 3513), prior to the start of ground disturbance or vegetation removal, a pre-construction surveys shall be conducted to avoid impacts to avian species.
Removal of any trees, shrubs or any other potential nesting and foraging habitat for avian and/or sensitive avian species shall be conducted outside of the nesting season to the greatest extent practical. Alternatively, a nesting bird survey shall be conducted within three (3) days prior to the start of work if work is to occur during the nesting bird season (January 31 – September 15). The survey results shall be provided to the City’s Planning Department. The Project Applicant shall adhere to the following:
1. Applicant shall designate a biologist (Designated Biologist) experienced in:
identifying local and migratory bird species of special concern; conducting bird surveys using appropriate survey methodology; nesting surveying techniques, recognizing breeding and nesting behaviors, locating nests and breeding territories, and identifying nesting stages and nest success; determining/ establishing appropriate avoidance and minimization measures; and monitoring the efficacy of implemented avoidance and minimization measures.
2. Pre-activity field surveys shall be conducted at the appropriate time of day/night, during appropriate weather conditions, no more than 3 days prior to the initiation of Project activities. Surveys shall encompass all suitable areas including trees, shrubs, bare ground, burrows, cavities, and structures. Survey duration shall take into consideration the size of the Project site; density, and complexity of the habitat; number of survey participants; survey techniques employed; and shall be sufficient to ensure the data collected is complete and accurate.
If nesting birds are not found within the project site, site preparation and construction activities may begin during the nesting/breeding season. If nesting birds or active nests

(including nesting raptors) are identified, then avoidance or minimization measures shall be undertaken in consultation with the City of San Jacinto (and California Department of Fish and Wildlife if the observed species has special status). Measures shall include immediate establishment of an avoidance buffer be implemented as determined by a qualified biologist and approved by the City of San Jacinto, based on their best professional judgement and experience. The buffer shall be of a distance to ensure avoidance of adverse effects to the nesting bird by accounting for topography, ambient conditions, species, nest location, and activity type. The buffer around the nest shall be delineated and flagged, and all work within these buffers shall be halted until a qualified biologist determines the nesting effort is finished (i.e., the juveniles are surviving independent from the nest or the nest has failed). The biologist shall monitor the nest at the onset of project activities, and at the onset of any changes in such project activities (e.g., increase in number or type of equipment, change in equipment usage, etc.) to determine the efficacy of the buffer. If the biologist determines that such project activities may be causing an adverse reaction, the biologist shall adjust the buffer accordingly or implement alternative avoidance and minimization measures, such as redirecting or rescheduling construction or erecting sound barriers. The onsite biologist shall review and verify compliance with these nesting boundaries and shall verify the nesting effort has finished (i.e., the juveniles are surviving independent from the nest). All nests shall be monitored as determined by the qualified biologist until nestlings have fledged and dispersed or it is otherwise confirmed that the nest has been unsuccessful or abandoned. Work can resume within the buffer area when no other active nests are found. If vegetation clearing is not initiated within 72 hours of a negative survey during the nesting season, the nesting survey must be repeated to confirm the absence of nesting birds. Upon completion of the survey and nesting bird monitoring, a report shall be prepared and submitted to City of San Jacinto Planning Division for mitigation monitoring compliance record keeping.
BIO-2 To avoid impacts to special-status bat species and identify roosting habitat, a preconstruction bat survey shall be conducted by a qualified bat biologist prior to initiation of Project activities. The survey shall be conducted within the Project site and 100-foot buffer during appropriate weather conditions per the bat biologist’s recommendations. If bats are identified, the qualified bat biologist shall identify the bats to the species level and evaluate the colony to determine its size and significance, and presence of a maternal colony. If any evidence of bat occupation is identified during the survey, the qualified bat biologist shall then provide additional measures to avoid impacts to roosting bats, and if the observed species has special status, as recommended by the California Department of Fish and Wildlife (CDFW). Measures provided shall be specific to the individual roost species present, and proposed construction activities, and shall include: a) postponement of Project activities within a no-work buffer specified by the bat biologist to outside of the bat maternity season (typically, maternity season is April 1 through August 31) if a maternity colony is identified to be present and b) monitoring of Project activities by a qualified bat biologist. Project activities that do not produce noise or vibrations substantially higher than ambient conditions may be conducted if a nonmaternal roosting colony is present at the qualified bat biologist’s discretion. If the qualified bat biologist determines that nonmaternal colony roosting bats are disturbed by construction activities, construction activities shall cease immediately and additional avoidance measures (e.g.,

installation of a noise shroud or sound curtain) shall be required before activities resume.
If a maternity colony is present, tree removal and/or modification shall occur outside the bat maternity season (typically April 1 through August 31) in the fall (after flightless young have become volant as determined by the qualified bat biologist) and under the supervision of a qualified bat biologist.
BIO-3: To avoid project-related impacts to burrowing owls potentially occurring on or in the vicinity of the Project site, a preconstruction presence/absence survey for burrowing owl in accordance with the March 2006 Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan Area shall be conducted by a qualified biologist within 30 days prior to the commencement of ground disturbing activities including vegetation clearing, grubbing, tree removal, or site watering. In addition, a preconstruction survey for burrowing owl shall be conducted within three (3) days prior to initiation of Project activities and reported to California Department of Fish and Wildlife (CDFW). Additionally, if ground-disturbing activities occur, but the site is left undisturbed for more than 30 days, a pre-construction survey shall again be necessary to minimize the possibility burrowing owl have not colonized the site since it was last disturbed. If burrowing owls are found, the same coordination described above shall be necessary.
If no burrowing owls are observed during the survey, site preparation and construction activities may begin. If burrowing owl are present within the survey area, then avoidance or minimization measures shall be undertaken in consultation with the City of San Jacinto, CDFW and U.S. Fish and Wildlife Service (USFWS). CDFW shall be sent written notification within 48 hours of detection of burrowing owls. If active nests are identified on an implementing project site during the preconstruction survey, the Project applicant shall not commence activities within 500 feet until no sign is present that the burrows are being used by adult or juvenile owls or following CDFW approval of a Burrowing Owl Plan as described below. If owl presence is difficult to determine, a qualified biologist shall monitor the burrows with motion-activated trail cameras for at least 24 hours to evaluate burrow occupancy. The onsite qualified biologist shall verify the nesting effort has finished according to methods identified in the Burrowing Owl Plan.
The qualified biologist and Project Applicant shall coordinate with the City, CDFW, and USFWS to develop a Burrowing Owl Plan to be approved by the City, CDFW, and USFWS prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed avoidance, relocation, monitoring, minimization, and/or mitigation actions. The Burrowing Owl Plan shall include the number and location of occupied burrow sites and details on proposed buffers if avoiding the burrowing owls or information on the adjacent or nearby suitable habitat available to owls for relocation. If no suitable habitat is available nearby for relocation, details regarding the creation and funding of artificial burrows (numbers, location, and type of burrows) and management activities for relocated owls shall also be included in the Burrowing Owl Plan. The City shall implement the Burrowing Owl Plan following CDFW and USFWS review and approval.
If burrowing owls are observed within Project Site(s) during Project implementation and construction, the Project applicant shall notify CDFW immediately in writing within 48 hours of detection. A Burrowing Owl Plan shall be submitted to CDFW for review and

approval within two weeks of detection and no Project activity shall continue within 500 feet of the burrowing owls until CDFW approves the Burrowing Owl Plan. The City shall be responsible for implementing appropriate avoidance and mitigation measures, including burrow avoidance, passive or active relocation, or other appropriate mitigation measures as identified in the Burrowing Owl Plan.
A final report shall be prepared by a qualified biologist documenting the results of the burrowing owl surveys and detailing avoidance, minimization, and mitigation measures.
The final report shall be submitted to the City and CDFW within 30 days of completion of the survey and burrowing monitoring for mitigation monitoring compliance record keeping.
CULTURAL RESOURCES
CR-1: This Mitigation Monitoring and Reporting Program (MMRP) to mitigate potential impacts to undiscovered buried cultural resources within the Project shall be implemented to the satisfaction of the lead agency. This program shall include, but not be limited to, the following actions:
1) Prior to issuance of a grading permit, the applicant shall provide written verification that a certified archaeologist has been retained to implement the monitoring program. This verification shall be presented in a letter from the Project archaeologist to the lead agency.
2) The Project applicant shall provide Native American monitoring during grading. The Native American monitor shall work in concert with the archaeological monitor to observe ground disturbances and search for cultural materials. The Lead Agency shall coordinate with the consulting Tribe to facilitate communications with the Project developer/ applicant so that all Parties can develop a mutually-acceptable Tribal Monitoring and Treatment Agreement (or Treatment and Disposition Agreement (TDA)), which includes the scope of monitoring, scheduling of monitors from the consulting Tribe, and the course of action for inadvertent discoveries. 3) The Project archaeologist, in consultation with the consulting Tribe, the contractor, and the City, shall implement a Cultural Resources Management Plan (CRMP) to address the details, timing and responsibility of all archaeological and cultural activities that will occur on the Project site. Details in the Plan shall include:
a) Project grading and development scheduling;
b) The Project archaeologist and the Consulting Tribe shall attend the pregrading meeting with the City, the construction manager and any contractors and shall conduct a mandatory Cultural Resources Worker Sensitivity Training to those in attendance. The Training shall include a brief review of the cultural sensitivity of the Project and the surrounding area; what resources could potentially be identified during earthmoving activities; the requirements of the monitoring program; the protocols that apply in the event inadvertent discoveries of cultural resources are identified, including who to contact and appropriate avoidance measures

until the find(s) can be properly evaluated; and any other appropriate protocols.
c) The protocols and stipulations that the contractor, City, consulting Tribe and Project archaeologist shall follow in the event of inadvertent cultural resources discoveries, including any newly discovered cultural resource deposits that shall be subject to a cultural resources evaluation. 4) During the original cutting of previously undisturbed deposits, the archaeological monitor(s) and tribal representative shall be onsite, as determined by the consulting archaeologist, to perform periodic inspections of the excavations.
Monitoring is recommended in younger Holocene alluvial soils, estimated to occur within near surface soils to a depth of five (5) to ten (10) feet. The frequency of inspections will depend upon the rate of excavation, the materials excavated, and the presence and abundance of artifacts and features. The consulting archaeologist shall have the authority to modify the monitoring program if the potential for cultural resources appears to be less than anticipated. 5) Isolates and clearly non-significant deposits shall be minimally documented in the field so the monitored grading can proceed.
6) In the event that previously unidentified cultural resources are discovered, the archaeologist shall have the authority to divert or temporarily halt ground disturbance operation in the area of discovery to allow for the evaluation of potentially significant cultural resources. The archaeologist shall contact the lead agency at the time of discovery. The archaeologist, in consultation with the lead agency, shall determine the significance of the discovered resources. The lead agency must concur with the evaluation before construction activities are allowed to resume in the affected area. For significant cultural resources, a Research Design and Data Recovery Program to mitigate impacts shall be implemented by the consulting archaeologist and approved by the lead agency before being carried out using professional archaeological methods. If any human remains are discovered, the county coroner and lead agency shall be contacted. In the event that the remains are determined to be of Native American origin, the Most Likely Descendant (as identified by the NAHC) shall be contacted in order to determine proper treatment and disposition of the remains.
a) Before construction activities are allowed to resume in the affected area, the artifacts shall be recovered, and features recorded using professional archaeological methods. The Project archaeologist in consultation with the consulting Tribe shall determine the amount of material to be recovered for an adequate artifact sample for analysis.
b) One or more of the following treatments, in order of preference, shall be used in the event of a discovery:
i. Preservation-in-Place. Avoidance, or preservation-in-place, involves leaving a resource where it was found with no
development affecting its integrity. Pursuant to Public Resources

Code Section 21083.2(b) avoidance is the preferred method of preservation for archaeological and cultural resources. ii. Reburial on the Project site in an area not subject to future disturbance. Reburial of a resource shall include provisions to protect the selected reburial area from any future impacts in perpetuity. Reburial shall not occur until all required cataloging and basic recording have been completed, with the exception of sacred items, burial goods and Native American human remains. Any reburial process shall be culturally appropriate. The listing of contents and the location of the reburial shall be included in a confidential Phase IV monitoring report.
c) If Preservation-in-Place or reburial is not feasible, all cultural material collected during the grading monitoring program shall be processed and curated according to the current professional repository standards in a Riverside County curation facility that meets State Resources Department Office of Historic Preservation Guidelines for the Curation of Archaeological Resources (OHP 1993). The collections and associated records shall be transferred, including title and accompanied by payment of the fees necessary for permanent curation.
7) A Phase IV Monitoring Report documenting the field and analysis results and interpreting the artifact and research data within the research context shall be completed and submitted to the satisfaction of the lead agency prior to the issuance of any building permits. The report shall include DPR Primary and Archaeological Site Forms. The Phase IV Report shall be filed with the City under a confidential cover and not subject to Public Records Request and a copy of the report shall be submitted to the consulting Tribe.
GEOLOGY, SOILS AND PALEONTOLOGY
GEO-1: Prior to issuance of a building permit and certificate of occupancy, the Applicant and City shall verify that no habitable structures are proposed or constructed within the restricted use zone (RUZ) as currently delineated or as adjusted by a licensed geotechnical engineer.
GEO-2: Prior to issuance of grading permits, the City of San Jacinto shall confirm that grading and construction plans for the Project adequately incorporate the design recommendations (or alternative equivalent measures) detailed in the Geotechnical Investigations prepared by Sladden Engineering in March 2021 and June 2022. The design recommendations shall address site earthwork and grading (stripping, preparation of building areas, compaction, shrinkage and subsidence); footings; pavement design; slabs; retaining walls; corrosion series; utility trench backfill; exterior concrete flatwork; and drainage.
PALEO-1: Prior to issuance of a grading permit, the Applicant shall retain a qualified paleontological monitor to implement a paleontological monitoring program as follows:
a) Monitoring of mass grading and excavation activities in areas identified as likely to contain paleontological resources shall be performed by a qualified

paleontologist or paleontological monitor. Monitoring for paleontological resources shall be conducted in areas where grading, excavation, or drilling activities occur in Pleistocene and older Holocene alluvial soils, estimated at five (5) feet below the surface, in order to mitigate any adverse impacts (loss or destruction) to potential nonrenewable paleontological resources. Monitoring of any artificial fill or disturbed soils that may be present at the project is not warranted.
b) The paleontological monitor shall be equipped to salvage fossils as they are unearthed to avoid construction delays and to remove samples of sediment that are likely to contain the remains of small fossil invertebrates and vertebrates. The monitor shall be empowered to temporarily halt or divert equipment to allow for the removal of abundant or large specimens in a timely manner. Monitoring shall be reduced if the potentially fossiliferous units are not present in the subsurface, or if they are present, are determined upon exposure and examination by qualified paleontological personnel to have low potential to contain fossil resources. c) Preparation of recovered specimens to a point of identification and permanent preservation, including screen-washing sediments to recover small vertebrates and invertebrates if indicated by the results of test sampling. Preparation of any individual vertebrate fossils is often more time-consuming than for accumulations of invertebrate fossils.
d) All fossils shall be deposited in an accredited institution (university or museum) that maintains collections of paleontological materials. The Western Science Center in Hemet, California, is the preferred institution by the County of Riverside.
All costs of the paleontological monitoring and mitigation program, including any one-time charges by the receiving institution, are the responsibility of the developer.
e) A final monitoring and mitigation report of findings and significance, including lists of all fossils recovered and necessary maps and graphics to accurately record their original location(s), shall be prepared. A letter documenting receipt and acceptance of all fossil collections by the receiving institution must be included in the final report. The report, when submitted to and accepted by the appropriate lead agency (e.g., the City of San Jacinto), shall signify satisfactory completion of the project program to mitigate impacts to any nonrenewable paleontological resources.
HYDROLOGY AND WATER QUALITY
HYDRO-1: Prior to issuance of a grading permit, the applicant shall obtain coverage under a General Construction Permit issued from the State Water Resources Control Board. The General Construction Permit would require the filing of a Notice of Intent with the State Water Resources Control Board and the preparation of a Storm Water Pollution Prevention Plan (SWPPP).

1.0 Introduction
In compliance with requirements of the California Environmental Quality Act (CEQA) Public Resources Code Section 21000 et seq. and the CEQA Guidelines, the City of San Jacinto (City) prepared a Draft Initial Study/ Mitigated Negative Declaration (Draft IS/MND) for the San Jacinto Residential Development Project (State Clearinghouse No. 2023040304). The Draft IS/MND was circulated for public review and comment from April 12, 2023 to May 15, 2023.
One comment letter was received by the California Department of Fish and Wildlife (CDFW) on May 15, 2023. No other comments or comment letters were received from the public or other responsible or trustee agencies. The City, as the Lead Agency, has evaluated the comments received on the Project Draft IS/MND and prepared responses within this document. CDFW’s comment letter is included on the following pages in Section 2.0. The comments have been assigned a bracket and reference number for corresponding responses that are presented after the letter in its entirety. Responses to comments are presented in Section 3.0.
The City has determined that the findings and significance determinations presented in the circulated Draft IS/MND do not require changes to the Draft IS/MND based on comments received. The City has considered CDFW’s comments and made modifications to proposed mitigation measures based on CDFW’s recommendations. Revisions made to the mitigation serve to augment and clarify mitigation requirements but do not constitute significant or new information. The revisions are shown in responses to the corresponding comments; additions are shown in bold and deletions in strikethrough. The modified mitigation measures will be incorporated in the Project’s final Mitigation Monitoring and Reporting Program (MMRP).

Responses to Introduction Comments
IC-1 – The California Department of Fish and Wildlife (“CDFW” or “Commenter”) acknowledges receipt of the Notice of Intent for the Project’s Draft Mitigated Negative Declaration/Initial Study (IS/MND) and thanks the City for the opportunity to review aspects of the Project that relate to resources under CDFW’s purview.
No further response or action is required.
IC-2 – The Commentor provides a summary of their role as a Trustee Agency and Responsible Agency over fish and wildlife resources as it relates to the California Environmental Quality Act (CEQA), Fish and Game Code, lake and stream alterations, California Endangered Species Act (CESA), and the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP). No further response or action is required.
IC-3 – The Commentor provides a summary of the Project Description and Location of the Project. No further response or action is required.
Responses to Comments and Recommendations
CR-1 – The Commentor states comments and recommendations are being offered to assist the City in adequately identifying, avoiding, and/or mitigating significant or potentially significant impacts on biological resources. The Commentor also recommends measures or revisions to measures below be included in a science-based monitoring program that contains adaptive management strategies as part of the Project’s CEQA mitigation, monitoring, and reporting program (MMRP).
Mitigation measures BIO-1(a), BIO-1(b) and BIO-2 have been modified based on CDFW’s recommendations and are presented below in the responses to comments specific to that measure. The City has determined the final measures are adequate and science-based as informed by the Project’s biological resources technical evaluations and surveys, which were conducted pursuant to industry standards and protocols.
Results of these evaluations and surveys were included in the Draft IS/MND Appendix B Biological Technical Report and summarized in the Draft IS/MND Section 4.4 Biological Resources. The measures have also been determined to provide adequate adaptive management strategies; for example, including additional management procedures in the event a sensitive species is detected during required pre-construction surveys. No further response or action is required.
CR-2 – The Commentor discusses CEQA requirements for analyzing potential inconsistencies-with/impactsto general plans and local plans, including the MSHCP. The comment also states that projects need to demonstrate consistency with the MSHCP to be considered a covered activity under the MSHCP. The comment also states the Project must pay Local Development Fees and demonstrate compliance with specific sections of the MSHCP related to protection of species associated with riparian/riverine areas and vernal pools; protection of narrow endemic plant species; the Urban/Wildlands Interface Guidelines; and the Best Management Practices (BMPs) and siting, construction, design, operation and maintenance guidelines.
A MSHCP consistency analysis was included in the Draft IS/MND Section 4.4 Biological Resources under response to CEQA question “f)” and the Project has been determined consistent with the MSHCP. The Project will be subject-to and will pay all required local development fees, including those required for

SC-1 – The Commentor states that the Project may have a significant impact on burrowing owl, resulting from construction activities and/or habitat loss; states that no additional details (the survey dates, times, etc.) were provided regarding the burrowing owl surveys mentioned within the Draft IS/MND and notes a report is required detailing results of the habitat assessment with photographs and indicating whether the Project site contains suitable burrowing owl habitat and burrow locations; states there is insufficient information to determine if the proposed mitigation measure BIO-1(a) would reduce impacts to below significant; states the proposed 500-foot no-work buffer may be inadequate and proposes a 1,000-foot nowork buffer; and recommends modifications to the mitigation measure BIO-2.
A Project-specific analysis and burrowing owl focus surveys were prepared to determine potential for significant impacts on burrowing owl. Detailed specifics regarding survey dates and times were included in Appendix D MSHCP Burrowing Owl Survey Report of the Draft IS/MND’s Appendix B Biological Technical Report for those interested in understanding the precise methods for how the surveys were conducted.
The MSHCP Burrowing Owl Survey Report contains the habitat assessment with photographs and mapped burrow locations as noted in the comment. The 500-foot no-work buffer is consistent with the recommended distance described in the Burrowing Owl Survey Instructions for the Western Riverside Multiple Species Habitat Conservation Plan Area and there is nothing unique about this Project, such as blasting or pile driving, that warrants consideration of an increased buffer distance beyond standard protocols. Based on results of the survey work and in consideration of Project activities analyzed in the Draft IS/MND, the City has determined the Draft IS/MND’s analysis for potential impacts on burrowing owl and required mitigation is adequate. Nonetheless, the City has modified mitigation measure BIO-2 shown below based on CDFW’s recommendations. No further response or action is required.
BIO-32: To avoid project-related impacts to burrowing owls potentially occurring on or in the vicinity of the Project site, A a preconstruction presence/absence survey for burrowing owl in accordance with the March 2006 Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan Area within the Project footprint where suitable habitat is present will shall be conducted by a qualified biologist within 30 days prior to the commencement of ground disturbing activities including vegetation clearing, grubbing, tree removal, or site watering. In addition, a preconstruction survey for burrowing owl shall be conducted within 3 days prior to initiation of Project activities and reported to California Department of Fish and Wildlife (CDFW). Additionally, if ground-disturbing activities occur, but the site is left undisturbed for more than 30 days, a pre-construction survey shall again be necessary to minimize the possibility burrowing owl have not colonized the site since it was last disturbed. If burrowing owls are found, the same coordination described above shall be necessary.
If no burrowing owls are observed during the survey, site preparation and construction activities may begin. If burrowing owl have colonized the Project footprint prior to initiation of construction

are present within the survey area, the Project proponent shall immediately inform the City and Wildlife Agencies and shall prepare a Burrowing Owl Protection and Relocation Plan as well as a Determination of Biologically Equivalent or Superior Preservation (DBESP) for approval by the City and Wildlife Agencies prior to initiating ground disturbance then avoidance or minimization measures shall be undertaken in consultation with the City of San Jacinto, CDFW and US Fish and Wildlife Service (USFWS). CDFW shall be sent written notification within 48 hours of detection of burrowing owls. If active nests are identified on an implementing project site during the preconstruction survey, the Project applicant shall not commence activities within 500 feet until no sign is present that the burrows are being used by adult or juvenile owls or following CDFW approval of a Burrowing Owl Plan as described below. If owl presence is difficult to determine, a qualified biologist shall monitor the burrows with motion-activated trail cameras for at least 24 hours to evaluate burrow occupancy. The onsite qualified biologist shall verify the nesting effort has finished according to methods identified in the Burrowing Owl Plan.
The qualified biologist and Project Applicant shall coordinate with the City, CDFW, and USFWS to develop a Burrowing Owl Plan to be approved by the City, CDFW, and USFWS prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed avoidance, relocation, monitoring, minimization, and/or mitigation actions. The Burrowing Owl Plan shall include the number and location of occupied burrow sites and details on proposed buffers if avoiding the burrowing owls or information on the adjacent or nearby suitable habitat available to owls for relocation. If no suitable habitat is available nearby for relocation, details regarding the creation and funding of artificial burrows (numbers, location, and type of burrows) and management activities for relocated owls shall also be included in the Burrowing Owl Plan. The City shall implement the Burrowing Owl Plan following CDFW and USFWS review and approval.
If burrowing owls are observed within Project Site(s) during Project implementation and construction, the Project applicant shall notify CDFW immediately in writing within 48 hours of detection. A Burrowing Owl Plan shall be submitted to CDFW for review and approval within two weeks of detection and no Project activity shall continue within 500 feet of the burrowing owls until CDFW approves the Burrowing Owl Plan. The City shall be responsible for implementing appropriate avoidance and mitigation measures, including burrow avoidance, passive or active relocation, or other appropriate mitigation measures as identified in the Burrowing Owl Plan.
A final report shall be prepared by a qualified biologist documenting the results of the burrowing owl surveys and detailing avoidance, minimization, and mitigation measures. The final report shall be submitted to the City and CDFW within 30 days of completion of the survey and burrowing monitoring for mitigation monitoring compliance record keeping.
SC-2 – The Commentor states that the Project may have a significant impact on nesting birds, resulting from loss of nesting and/or foraging habitat, construction disturbance and noise, and increased human presence; recommends preconstruction nesting bird surveys within 3 days of Project construction regardless of nesting season/time of year; states the Project may remove habitat by eliminating native vegetation that may support essential foraging and breeding habitat; and recommends modifications to mitigation measure BIO-1(a).
A Project-specific analysis on potential impacts to nesting birds is in the Draft IS/MND Section 4.4 Biological Resources under response to CEQA questions “a)” and “d)”.

analysis for potential impacts on nesting birds and required mitigation is adequate. As described in Section
4.4, Biological Resources, Existing Setting of the Draft IS/MND, the Project site is characterized by maintained open fields comprised of herbaceous non-native forbs (flowering plants) and grasses vegetated with a variety of non-native and early successional weedy plant species. The Project footprint does not support any sensitive vegetation communities. Nonetheless, the City has extended the preconstruction nesting bird survey window through September 15, which is standard practice, based on the comment and has modified mitigation measure BIO-1(a) shown below based on CDFW’s recommendations. No further response or action is required.
BIO-1(a): Preconstruction Survey. To maintain compliance with the Migratory Bird Treaty Act (MBTA and California Fish and Game Code Sections 3503, 3503.5, and 3513), prior to the start of ground disturbance or vegetation removal, a pre-construction surveys shall be conducted to avoid impacts to avian and bat species.
(a) Removal of any trees, shrubs or any other potential nesting and foraging habitat for avian and/or sensitive avian species shall be conducted outside of the nesting season to the greatest extent practical. Alternatively, a nesting bird survey shall be conducted within three (3) days prior to the start of work if work is to occur during the nesting bird season (January 31 – September 15) August 31). If vegetation removal occurs outside of nesting season or if no nesting birds are found, no further action is required. The survey results shall be provided to the City’s Planning Department.
The Project Applicant shall adhere to the following:
1. Applicant shall designate a biologist (Designated Biologist) experienced in: identifying local and migratory bird species of special concern; conducting bird surveys using appropriate survey methodology; nesting surveying techniques, recognizing breeding and nesting behaviors, locating nests and breeding territories, and identifying nesting stages and nest success; determining/establishing appropriate avoidance and minimization measures; and monitoring the efficacy of implemented avoidance and minimization measures.
2. Pre-activity field surveys shall be conducted at the appropriate time of day/night, during appropriate weather conditions, no more than 3 days prior to the initiation of Project activities. Surveys shall encompass all suitable areas including trees, shrubs, bare ground, burrows, cavities, and structures. Survey duration shall take into consideration the size of the Project site; density, and complexity of the habitat; number of survey participants; survey techniques employed; and shall be sufficient to ensure the data collected is complete and accurate.
If nesting birds are not found within the project site, site preparation and construction activities may begin during the nesting/breeding season. If nesting birds or active nests (including nesting raptors) are identified, then avoidance or minimization measures shall be undertaken in consultation with the City of San Jacinto (and California Department of Fish and Wildlife if the observed species has special status). Measures shall include immediate establishment of an avoidance buffer be implemented as determined by a qualified biologist and approved by the City of San Jacinto, based on their best professional judgement and experience. the biologist shall establish appropriate buffers around the nest (typically 500 feet for raptors and sensitive species, 200 feet for non-raptors/non-sensitive species). The buffer shall be of a distance to ensure avoidance of adverse effects to the nesting bird by accounting for topography, ambient conditions,

species, nest location, and activity type. The buffer around the nest shall be delineated and flagged, and all work within these buffers shall be halted until a qualified biologist determines the nesting effort is finished (i.e., the juveniles are surviving independent from the nest or the nest has failed).
The biologist shall monitor the nest at the onset of project activities, and at the onset of any changes in such project activities (e.g., increase in number or type of equipment, change in equipment usage, etc.) to determine the efficacy of the buffer. If the biologist determines that such project activities may be causing an adverse reaction, the biologist shall adjust the buffer accordingly or implement alternative avoidance and minimization measures, such as redirecting or rescheduling construction or erecting sound barriers. The onsite biologist shall review and verify compliance with these nesting boundaries and shall verify the nesting effort has finished (i.e., the juveniles are surviving independent from the nest). All nests shall be monitored as determined by the qualified biologist until nestlings have fledged and dispersed or it is otherwise confirmed that the nest has been unsuccessful or abandoned. Work can resume within the buffer area when no other active nests are found. Alternatively, a qualified biologist may determine that certain work can be permitted within the buffer areas and shall develop a monitoring plan to prevent any impacts while the nest continues to be active (i.e., has eggs or chicks). If vegetation clearing is not initiated within 72 hours of a negative survey during the nesting season, the nesting survey must be repeated to confirm the absence of nesting birds. Upon completion of the survey and nesting bird monitoring, a report shall be prepared and submitted to City of San Jacinto Planning Division for mitigation monitoring compliance record keeping.
(b) Trees and large shrubs shall be surveyed for the presence of special status bat species by a qualified bat biologist no more than two weeks prior to the initiation of vegetation removal or ground disturbing activities if work will begin within the maternity season (March 1 to August 31).
Surveys may entail direct inspection of the trees and large shrubs or nighttime surveys as determined by a qualified biologist. If active bat roosts are present, a qualified bat biologist shall determine the species of bats present and the type of roost (i.e., day roost, night roost, maternity roost). If special-status bat species are present, a qualified bat biologist shall determine appropriate avoidance measures, which may include implementation of a construction-free buffer around the active roost.
SC-3 – The Commentor states that the Project may have a significant impact on bats, including Western red bat and Western yellow bat resulting from construction activities; states that site-specific focused surveys are necessary to determine if bats and roosts are present in a variety of natural and human-made environments that modeling may have missed including caves, rocky crevices, cliffs, abandoned mines, barns, buildings, culverts, and bridges; states that the MND does not state how an active hibernacula or maternity roost would be avoided, if detected; states that no compensatory mitigation is proposed and the Project could result in loss of roosting habitat; states that the current proposed mitigation could result in population decline of Species of Special Concern (SSC), based on the above summarized comments, potentially requiring a mandatory findings of significance under CEQA; and recommends modifying the current bat mitigation under BIO-1(b).
A Project-specific analysis on potential impacts to bats is in the Draft IS/MND Section 4.4 Biological Resources under response to CEQA questions “a)” and “d)”. Based on results of the survey work and in consideration of Project activities analyzed in the Draft IS/MND, the City has determined the Draft IS/MND’s analysis for potential impacts on bats is adequate and that proposed measure BIO-1(b) requires appropriate mitigation that is roughly proportionate to the potential risk of impacting bats. Focused surveys were not recommended by the Project biologist due to the moderate potential for foraging and the limited amount

of potentially suitable roosting habitat, consisting of a few isolated palm trees and single cottonwood tree.
The Project footprint does not contain caves, rocky crevices, cliffs, abandoned mines, barns, buildings, culverts, or bridges. As stated in Section 4.4 Biological Resources, Existing Setting, Avian Nesting and Bat Roosts, the biologists did not observe signs of bat roosting within the Project footprint during the July/August 2021 or March/April 2022 biological surveys. Mitigation Measure BIO-1(b) states that if specialstatus bat species are present, a qualified bat biologist shall determine appropriate avoidance measures, which may include implementation of a construction-free buffer around the active roost. Compensatory mitigation is not proposed as a potential loss of roosting habitat is considered de minimis. In addition, the proposed Project could also create suitable roosting habitat with new landscaping and structures. Based on the analysis provided in the Draft IS/MND, no decline in an SSC population would occur and no revisions to the mandatory findings section is needed. Nonetheless, the City has modified mitigation measure BIO1(b) shown below based on CDFW’s recommendations. No further response or action is required.
BIO-21(b): To avoid impacts to special-status bat species and identify roosting habitat, a preconstruction bat survey shall be conducted by a qualified bat biologist prior to initiation of Project activities. The survey shall be conducted within the Project site and 100-foot buffer during appropriate weather conditions per the bat biologist’s recommendations. If bats are identified, the qualified bat biologist shall identify the bats to the species level and evaluate the colony to determine its size and significance, and presence of a maternal colony. If any evidence of bat occupation is identified during the survey, the qualified bat biologist shall then provide additional measures to avoid impacts to roosting bats, and if the observed species has special status, as recommended by the California Department of Fish and Wildlife (CDFW). Measures provided shall be specific to the individual roost species present, and proposed construction activities, and shall include: a) postponement of Project activities within a no-work buffer specified by the bat biologist to outside of the bat maternity season (typically, maternity season is April 1 through August 31) if a maternity colony is identified to be present and b) monitoring of Project activities by a qualified bat biologist. Project activities that do not produce noise or vibrations substantially higher than ambient conditions may be conducted if a nonmaternal roosting colony is present at the qualified bat biologist’s discretion. If the qualified bat biologist determines that nonmaternal colony roosting bats are disturbed by construction activities, construction activities shall cease immediately and additional avoidance measures (e.g., installation of a noise shroud or sound curtain) shall be required before activities resume. If a maternity colony is present, tree removal and/or modification shall occur outside the bat maternity season (typically April 1 through August 31) in the fall (after flightless young have become volant as determined by the qualified bat biologist) and under the supervision of a qualified bat biologist.
SC-4 – The Commentor states impacts to a human made interim channel identified in the Draft IS/MND may be subject to Fish and Game Code section 1600 based on information provided in the Draft IS/MND and aerial photography; states that the interim channel is hydrologically connected to the San Jacinto River; states that an impact could result through the deposition of debris, waste or other materials that could pass into any river, stream, or lake resulting from changes to onsite hydrology; and states that it is likely the applicant will need to notify CDFW to determine whether a Streambed Alteration Agreement is needed.
The Commentor then proposes a mitigation measure requesting four pieces of information for CDFW to determine if a Streambed Alteration Agreement is required, and if required, details recommendations for compensatory mitigation should a jurisdictional feature be impacted.
A presence/absence jurisdictional delineation was prepared for the Project, which entailed database research of mapped waters in the National Wetlands Inventory, review of aerial photography, and field

survey of the site. No jurisdictional features were observed. As discussed in the Draft IS/MND Section 4.4 Biological Resources, Existing Setting, Jurisdictional Waters, the interim channel is an excavated upland channel with no natural flow of water and lacks riparian or wetland vegetation. In addition, there is no historic drainage course that connects to this channel, and the only source of water flow is through pumping from an upstream concrete lined facility that stores urban runoff. In response to this comment, additional research was done regarding this feature to further rule out the channel as jurisdictional. The City’s public works department confirmed a floating pump is located in the completed portion of Line C (currently a concrete basin) that activates when the concrete basin is at a certain capacity to pump excess water into the earthen portion of the interim channel. There is no current evident connection to the San Jacinto River, which is located approximately 2.2 miles away. In addition, Section 4.10, Hydrology and Water Quality of the Draft IS/MND analyzed potential impacts to hydrology and water quality and determined the Project’s two proposed onsite detention/infiltration basins would adequately manage water flows and water quality after the Project is constructed. Mitigation measure HYDRO-1 is also included to manage flows and protect water quality during temporary construction activities. Based on the information provided in the Draft IS/MND and augmented by the additional research, the Project footprint does not impact a jurisdictional feature subject to a Streambed Alteration Agreement.
To further address the comment, responses to the four pieces of information requested by CDFW are presented below followed by a response:
Request 1. A stream delineation including the bed, bank and channel.
Response 1. A presence/absence jurisdictional delineation was prepared for the Project and jurisdictional features were determined absent from the Project footprint.
Request 2. Linear feet and/or acreage of streams and associated natural communities that would be permanently and/or temporarily impacted by the Project. This includes impacts as a result of routine maintenance and fuel modification. Plant community names should be provided based on vegetation association and/or alliance per the Manual of California Vegetation (Sawyer et al 2009).
Response 2. Again, the presence/absence jurisdictional delineation results disclosed in the Draft IS/MND identified no features onsite or riparian vegetation. The Project site is characterized by maintained open fields comprised of herbaceous non-native forbs and grasses vegetated with a variety of non-native and early successional weedy plant species.
Request 3. A discussion as to whether impacts on streams within the Project site would impact those streams immediately outside of the Project site where there is hydrologic connectivity.
Potential impacts such as changes to drainage pattern, runoff, and sedimentation should be discussed.
Response 3. As previously discussed, the excavated upland channel has no natural flow of water and lacks riparian or wetland vegetation. In addition, there is no historic drainage course that connects to this interim channel, and the only source of water flow is through pumping from an upstream concrete lined facility that stores urban runoff. The City’s public works department confirmed a floating pump is located in the completed portion of Line C (currently a concrete basin) that activates when the concrete basin is at a certain capacity to pump excess water into the earthen portion of the interim channel. There is no current evident connection to the San Jacinto River, which is located approximately 2.2 miles away.

Request 4. A hydrological evaluation of the 100-year storm event to provide information on how water and sediment is conveyed through the Project site.
Response 4. As discussed in the Draft IS/MND, Section 4.10 Hydrology and Water Quality, under response to question “d)”, the Project has been designed to maintain the existing drainage pattern on the Project site. The Project site is generally flat with sheet flow drainage moving from southeast to northwest. Based on additional information provided by the Project’s engineer, the undeveloped site transmits very little sediment offsite due to the aforementioned topography and natural grasses that are prevalent on the site. In the developed condition, stormwater runoff would be contained in public streets and the Project storm drain system. The flows would discharge to two separate detention basins for infiltration water treatment. The basins would act as settling basins thereby eliminating any transport.
No further response or action is required.
Additional Recommendations
AR-1 – The Commentor states a weed management plan should be developed to prevent non-native weeds from becoming established.
As discussed in the Draft IS/MND Section 4.0 Biological Resources, Existing Setting, Vegetation Communities, the Project site is characterized by maintained open fields comprised of herbaceous nonnative forbs and grasses vegetated with a variety of non-native and early successional weedy plant species.
Since the existing Project site contains weeds, is already maintained, would be completely developed, and is not located near a sensitive resource or habitat, a weed management plan is not proposed. In addition, weed abatement is enforced through the San Jacinto Municipal Code Section 8.44.050 Nuisances, C.
Property maintenance, 8., which states, “Dead, decayed, diseased or hazardous trees, weeds or other vegetation constituting unsightly appearance, dangerous to public safety and welfare or detrimental to neighboring properties or property values and visible from a public street. These include weeds of wingy and/or downy nature and/or attain such a large growth as to become a fire menace when dry. These weeds are considered seasonal and recurrent and shall not exist upon parkways, streets and private property within the City.” No further response or action is required.
AR-2 – The Commentor recommends updating the proposed biological resources mitigation measures with those recommended in the comment letter and includes an attached example MMRP that restates the recommended mitigation measure modifications described in previous comments above.
The City has modified mitigation measures BIO-1(a), BIO-1(b) and BIO-2 based on recommendations provided by CDFW to augment and clarify mitigation responsibilities. The modifications were made in consideration of the proposed Project’s potential impacts on biological resources as informed by the Project-specific technical analyses prepared as part of the Draft IS/MND. Mitigation measure requirements were refined to be commensurate with the potential risk for impacts. No further response or action is required.
AR-3 – The Commentor states negative declarations need to be maintained in a database and requests any special status species and natural community be reported to the California Natural Diversity Database (CNDDB).

MITIGATION MONITORING AND REPORTING PROGRAM
The California Environmental Quality Act (CEQA) requires that when a public agency completes an environmental document which includes measures to mitigate or avoid significant environmental effects, the public agency must adopt a reporting or monitoring plan. This requirement ensures that environmental impacts found to be significant will be mitigated. The reporting or monitoring plan must be designed to ensure compliance during project implementation (Public Resources Code Section 21081.6).
In compliance with Public Resources Code Section 21081.6, Table 1, Mitigation Monitoring and Reporting Checklist, has been prepared for the San Jacinto Residential Development Project (the “Project”). This Mitigation Monitoring and Reporting Checklist is intended to provide verification that all applicable Conditions of Approval relative to significant environmental impacts are monitored and reported. Monitoring will include: 1) verification that each mitigation measure has been implemented; 2) recordation of the actions taken to implement each mitigation; and 3) retention of records in the City of San Jacinto’s San Jacinto Residential Development Project (TTM 38202) (P21-076) file.
This Mitigation Monitoring and Reporting Program (MMRP) delineates responsibilities for monitoring the project, but also allows the City flexibility and discretion in determining how best to monitor implementation. Monitoring procedures will vary according to the type of mitigation measure.
Adequate monitoring consists of demonstrating that monitoring procedures took place and that mitigation measures were implemented. This includes the review of all monitoring reports, enforcement actions, and document disposition, unless otherwise noted in the Mitigation Monitoring and Reporting Checklist (Table 1). If an adopted mitigation measure is not being properly implemented, the designated monitoring personnel shall require corrective actions to ensure adequate implementation.
Reporting consists of establishing a record that a mitigation measure is being implemented, and generally involves the following steps:
• The City distributes reporting forms to the appropriate entities for verification of compliance. • Departments/agencies with reporting responsibilities will review the Initial Study/Mitigated Negative Declaration, which provides general background information on the reasons for including specified mitigation measures.
• Problems or exceptions to compliance will be addressed to the City as appropriate. • Periodic meetings may be held during project implementation to report on compliance of mitigation measures.
• Responsible parties provide the City with verification that monitoring has been conducted and ensure, as applicable, that mitigation measures have been implemented. Monitoring compliance may be documented through existing review and approval programs such as field inspection reports and plan review.
• The City prepares a reporting form periodically during the construction phase and an annual report summarizing all project mitigation monitoring efforts.

Minor changes to the MMRP, if required, would be made in accordance with CEQA and would be permitted after further review and approval by the City. Such changes could include reassignment of monitoring and reporting responsibilities, plan redesign to make any appropriate improvements, and/or modification, substitution or deletion of mitigation measures subject to conditions described in CEQA Guidelines Section 15162. No change will be permitted unless the MMRP continues to satisfy the requirements of Public Resources Code Section 21081.6.

MITIGATION MONITORING AND REPORTING PROGRAM
The California Environmental Quality Act (CEQA) requires that when a public agency completes an environmental document which includes measures to mitigate or avoid significant environmental effects, the public agency must adopt a reporting or monitoring plan. This requirement ensures that environmental impacts found to be significant will be mitigated. The reporting or monitoring plan must be designed to ensure compliance during project implementation (Public Resources Code Section 21081.6).
In compliance with Public Resources Code Section 21081.6, Table 1, Mitigation Monitoring and Reporting Checklist, has been prepared for the San Jacinto Residential Development Project (the “Project”). This Mitigation Monitoring and Reporting Checklist is intended to provide verification that all applicable Conditions of Approval relative to significant environmental impacts are monitored and reported. Monitoring will include: 1) verification that each mitigation measure has been implemented; 2) recordation of the actions taken to implement each mitigation; and 3) retention of records in the City of San Jacinto’s San Jacinto Residential Development Project (TTM 38202) (P21-076) file.
This Mitigation Monitoring and Reporting Program (MMRP) delineates responsibilities for monitoring the project, but also allows the City flexibility and discretion in determining how best to monitor implementation. Monitoring procedures will vary according to the type of mitigation measure.
Adequate monitoring consists of demonstrating that monitoring procedures took place and that mitigation measures were implemented. This includes the review of all monitoring reports, enforcement actions, and document disposition, unless otherwise noted in the Mitigation Monitoring and Reporting Checklist (Table 1). If an adopted mitigation measure is not being properly implemented, the designated monitoring personnel shall require corrective actions to ensure adequate implementation.
Reporting consists of establishing a record that a mitigation measure is being implemented, and generally involves the following steps:
• The City distributes reporting forms to the appropriate entities for verification of compliance. • Departments/agencies with reporting responsibilities will review the Initial Study/Mitigated Negative Declaration, which provides general background information on the reasons for including specified mitigation measures.
• Problems or exceptions to compliance will be addressed to the City as appropriate. • Periodic meetings may be held during project implementation to report on compliance of mitigation measures.
• Responsible parties provide the City with verification that monitoring has been conducted and ensure, as applicable, that mitigation measures have been implemented. Monitoring compliance may be documented through existing review and approval programs such as field inspection reports and plan review.
• The City prepares a reporting form periodically during the construction phase and an annual report summarizing all project mitigation monitoring efforts.

Minor changes to the MMRP, if required, would be made in accordance with CEQA and would be permitted after further review and approval by the City. Such changes could include reassignment of monitoring and reporting responsibilities, plan redesign to make any appropriate improvements, and/or modification, substitution or deletion of mitigation measures subject to conditions described in CEQA Guidelines Section 15162. No change will be permitted unless the MMRP continues to satisfy the requirements of Public Resources Code Section 21081.6.

SAN JACINTO, CALIFORNIA
AIR QUALITY and GREENHOUSE GAS STUDY
This report is an analysis of the potential air quality and greenhouse gas impacts associated with the proposed Tentative Tract Map 38202 in the City of San Jacinto, California. This report has been prepared by Birdseye Planning Group (BPG) under contract to the applicant, to support preparation of the environmental documentation pursuant to the California Environmental Quality Act (CEQA). This study analyzes the potential for temporary air quality and greenhouse gas impacts associated with construction activity and long‐term impacts associated with operation of the proposed project.
PROJECT DESCRIPTION
The proposed Project would develop an approximately 33.8‐acre vacant site with up to 181 single‐family residential homes and associated infrastructure. The Project requires subdividing five (5) existing parcels (APNs 436‐280‐011, 436‐280‐012, 436‐280‐013, 436‐280‐014 and 436‐280‐ 025) (Figure 1 – Vicinity Map). Lot sizes would vary within an approximate range of 5,000 to 8,000 square feet. The Project proposes to modify development standards and reduce the minimum RL lot size below 7,200 square feet and density above 2.1 units per acre as allowable under a Planned Development Permit (PDP), Site Plan, and Design Review. The preliminary site plan is shown on Figure 2 – Proposed Site Plan.
Access to the new development would be provided from Lyon Avenue/Appaloosa Drive and Marilyn Drive/Estrella Street. Internal vehicular and pedestrian circulation would be accessible on new streets and sidewalks that would be publicly maintained in the future. Parking would be accommodated in two‐car garages, two‐car driveways, and on public streets.
Offsite improvements include connecting the proposed internal circulation system to the intersections of Lyon Avenue/Appaloosa Drive and Marilyn Drive/Estrella Street; connecting to existing utility systems within Lyon Avenue; frontage improvements along Lyon Avenue including a Class I multi‐use path (per City of San Jacinto Trails Master Plan), sidewalk and street lights; and constructing a portion of the San Jacinto Valley Master Drainage Plan storm drain system Line G‐3 from Marilyn Drive/Estrella Street along the northeast edge of the development to a future connection point (note: continuation of Line G‐3 to be constructed by others) at the Monte Vista Middle School property to the north. Total off‐site improvements would comprise approximately 1.26 acres.
Project construction stages would include site preparation, import of fill soils, grading, building construction (and construction of offsite facilities), underground utility construction, export of lot spoils and street paving. Project construction is anticipated to begin in the first quarter of 2023 and end late in the first quarter of 2025.

4 SETTING
Air Pollution Regulation
The federal and state governments have been empowered by the federal and state Clean Air Acts to regulate emissions of airborne pollutants and have established ambient air quality standards for the protection of public health. The EPA is the federal agency designated to administer air quality regulation, while the California Air Resources Board (ARB) is the state equivalent in California. Federal and state standards have been established for six criteria pollutants, including ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulates less than 10 and 2.5 microns in diameter (PM10 and PM2.5), and lead (Pb).
California has also set standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility‐ reducing particles. Table 1 lists the current federal and state standards for each of these pollutants. Standards have been set at levels intended to be protective of public health.
California standards are generally more restrictive than federal standards for each of these pollutants except lead and the eight‐hour average for CO.
Local control in air quality management is provided by the ARB through county‐level or regional (multi‐county) Air Pollution Control Districts (APCDs). The ARB establishes air quality standards and is responsible for control of mobile emission sources, while the local APCDs are responsible for enforcing standards and regulating stationary sources. The ARB has established 15 air basins statewide. The project site is located within the South Coast Air Basin (Basin), which includes all of Orange County and the non‐desert portions of Los Angeles, Riverside, and San Bernardino Counties. Air quality conditions in the Basin are under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD is required to monitor air pollutant levels to ensure that air quality standards are met and, if they are not met, to develop strategies to meet the standards. Depending on whether the standards are met or exceeded, the local air basin is classified as being in “attainment” or “non‐attainment.” The Basin, in which the project area is located, is a non‐attainment area for both the federal and state standards for ozone and PM2.5. The Basin is designated nonattainment for state standards and a maintenance area for federal PM10 standards. For nitrogen oxide and carbon monoxide, the Basin is designated attainment for state standards and unclassified/attainment for federal standards. Characteristics of ozone, carbon monoxide, nitrogen dioxide, and suspended particulates are described below.
Ozone. Ozone is produced by a photochemical reaction (triggered by sunlight) between nitrogen oxides (NOX) and reactive organic gases (ROG)1. Nitrogen oxides are formed during the combustion of fuels, while reactive organic compounds are formed during combustion and 1 Organic compound precursors of ozone are routinely described by a number of variations of three terms: hydrocarbons (HC), organic gases (OG), and organic compounds (OC). These terms are often modified by adjectives such as total, reactive, or volatile, and result in a rather confusing array of acronyms: HC, THC (total hydrocarbons), RHC (reactive hydrocarbons), TOG (total organic gases), ROG (reactive organic gases), TOC (total organic compounds), ROC (reactive organic compounds), and VOC (volatile organic compounds). While most of these differ in some significant way from a chemical perspective, from an air quality perspective two groups are important: non-photochemically reactive in the lower atmosphere, or photochemically reactive in the lower atmosphere (HC, RHC, ROG, ROC, and VOC).

1. California standards for ozone, carbon monoxide (except 8‐hour Lake Tahoe), sulfur dioxide (1 and 24 hour), nitrogen dioxide, and particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations.
2. National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year. The ozone standard is attained when the fourth highest 8‐hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard.
For PM10, the 24‐hour standard is attained when the expected number of days per calendar year with a 24‐hour average concentration above 150 μg/m3 is equal to or less than one. For PM2.5, the 24‐hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard.
Contact the U.S. EPA for further clarification and current national policies.
3. Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr. Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 torr; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.
4. Any equivalent measurement method which can be shown to the satisfaction of the CARB to give equivalent results at or near the level of the air quality standard may be used.
5. National Primary Standards: The levels of air quality necessary, with an adequate margin of safety to protect the public health.
6. National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.
7. Reference method as described by the U.S. EPA. An “equivalent method” of measurement may be used but must have a “consistent relationship to the reference method” and must be approved by the U.S. EPA.
8. On October 1, 2015, the national 8‐hour ozone primary and secondary standards were lowered from 0.075 to
0.070 ppm.
9. On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 μg/ m3 to 12.0 μg/ m3.
The existing national 24‐hour PM2.5 standards (primary and secondary) were retained at 35 μg/ m3, as was the annual secondary standard of 15 μg/ m3. The existing 24‐hour PM10 standards (primary and secondary) of 150 μg/ m3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years.

7 10. To attain the 1‐hour national standard, the 3‐year average of the annual 98th percentile of the 1‐hour daily maximum concentrations at each site must not exceed 100 ppb. Note that the national 1‐hour standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the national 1‐hour standard to the California standards the units can be converted from ppb to ppm. In this case, the national standard of 100 ppb is identical to 0.100 ppm.
11. On June 2, 2010, a new 1‐hour SO2 standard was established and the existing 24‐hour and annual primary standards were revoked. To attain the 1‐hour national standard, the 3‐year average of the annual 99th percentile of the 1‐hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24‐hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated nonattainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved.
Note that the 1‐hour national standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the 1‐hour national standard to the California standard the units can be converted to ppm. In this case, the national standard of 75 ppb is identical to 0.075 ppm.
12. The CARB has identified lead and vinyl chloride as ʹtoxic air contaminantsʹ with no threshold level of exposure for adverse health effects determined. These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants.
13. The national standard for lead was revised on October 15, 2008 to a rolling 3‐month average. The 1978 lead standard (1.5 μg/ m3 as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved.
14. In 1989, the CARB converted both the general statewide 10‐mile visibility standard and the Lake Tahoe 30‐mile visibility standard to instrumental equivalents, which are ʺextinction of 0.23 per kilometerʺ and ʺextinction of
0.07 per kilometerʺ for the statewide and Lake Tahoe Air Basin standards, respectively. evaporation of organic solvents. Because ozone requires sunlight to form, it mostly occurs in concentrations considered serious between the months of April and October. Ozone is a pungent, colorless, toxic gas with direct health effects on humans including respiratory and eye irritation and possible changes in lung functions. Groups most sensitive to ozone include children, the elderly, people with respiratory disorders, and people who exercise strenuously outdoors.
Carbon Monoxide. Carbon monoxide is a local pollutant that is found in high concentrations only near the source. The major source of carbon monoxide, a colorless, odorless, poisonous gas, is automobile traffic. Elevated concentrations, therefore, are usually only found near areas of high traffic volumes. Carbon monoxide’s health effects are related to its affinity for hemoglobin in the blood. At high concentrations, carbon monoxide reduces the amount of oxygen in the blood, causing heart difficulties in people with chronic diseases, reduced lung capacity and impaired mental abilities.
Nitrogen Dioxide. Nitrogen dioxide (NO2) is a by‐product of fuel combustion, with the primary source being motor vehicles and industrial boilers and furnaces. The principal form of nitrogen oxide produced by combustion is nitric oxide (NO), but NO reacts rapidly to form NO2, creating the mixture of NO and NO2 commonly called NOX. Nitrogen dioxide is an acute irritant. A relationship between NO2 and chronic pulmonary fibrosis may exist, and an increase in bronchitis in young children at concentrations below 0.3 parts per million (ppm) may occur.

8 Nitrogen dioxide absorbs blue light and causes a reddish‐brown cast to the atmosphere and reduced visibility. It can also contribute to the formation of PM10 and acid rain.
Suspended Particulates. PM10 is particulate matter measuring no more than 10 microns in diameter, while PM2.5 is fine particulate matter measuring no more than 2.5 microns in diameter. Suspended particulates are mostly dust particles, nitrates and sulfates. Both PM10 and PM2.5 are by‐products of fuel combustion and wind erosion of soil and unpaved roads and are directly emitted into the atmosphere through these processes. Suspended particulates are also created in the atmosphere through chemical reactions. The characteristics, sources, and potential health effects associated with the small particulates (those between 2.5 and 10 microns in diameter) and fine particulates (PM2.5) can be very different. The small particulates generally come from windblown dust and dust kicked up from mobile sources. The fine particulates are generally associated with combustion processes as well as being formed in the atmosphere as a secondary pollutant through chemical reactions. Fine particulate matter is more likely to penetrate deeply into the lungs and poses a health threat to all groups, but particularly to the elderly, children, and those with respiratory problems. More than half of the small and fine particulate matter that is inhaled into the lungs remains there. These materials can damage health by interfering with the body’s mechanisms for clearing the respiratory tract or by acting as carriers of an absorbed toxic substance.
Toxic Air Contaminants/Diesel Particulate Matter. Hazardous air pollutants, also known as toxic air pollutants (TACs) or air toxics, are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. Examples of toxic air pollutants include:
benzene, which is found in gasoline;
perchloroethylene, which is emitted from some dry‐cleaning facilities; and methylene chloride, which is used as a solvent.
Transportation related emissions are focused on particulate matter constituents within diesel exhaust and TAC constituents that comprise a portion of total organic gas (TOG) emissions from both diesel and gasoline fueled vehicles. Diesel engine emissions are comprised of exhaust particulate matter and TOGs which are collectively defined as Diesel Particulate Matter (DPM).
DPM and TOG emissions from both diesel and gasoline fueled vehicles is typically composed of carbon particles and carcinogenic substances including polycyclic aromatic hydrocarbons, benzene, formaldehyde, acetaldehyde, acrolein, and 1,3‐butadiene. Diesel exhaust also contains gaseous pollutants, including volatile organic compounds and oxides of nitrogen (NOx).
Regional Climate and Local Air Quality
South Coast Air Basin. The combination of topography, low mean mixing height, abundant sunshine, and emissions from the second largest urban area in the United States gives the SCAB the worst air pollution problem in the nation. Climate in the SCAB is determined by its terrain and geographical location. The SCAB consists of a coastal plain with connecting broad valleys and low hills. The Pacific Ocean forms the southwestern border, and high mountains surround
4.1.l
Packet Pg. 559 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
9 the rest of the SCAB. The SCAB lies in the semi‐permanent high‐pressure zone of the eastern Pacific. The resulting climate is mild and is tempered by cool ocean breezes. This climatological pattern is rarely interrupted. However, periods of extremely hot weather, winter storms or easterly Santa Ana wind conditions can occur.
Annual average temperatures vary little throughout the SCAB, ranging from the low‐to‐middle 60s, measured in degrees Fahrenheit. With a more pronounced oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas. The majority of annual rainfall in the SCAB occurs between October and March. Summer rainfall is minimal and generally limited to scattered thundershowers in coastal regions and slightly heavier showers in the eastern portion of the SCAB and along the coastal side of the mountains.
Average temperatures in winter months in the project area range from a low of 34 degrees F to a high of 68 degrees F. In the summer, average temperatures range from a low of 59 degrees F to a high of 98 degrees F. During an average year, the greatest amount of precipitation, 2.86 inches, occurs in February.
The SCAQMD operates a network of 38 ambient air monitoring stations throughout the South Coast Air Basin. The purpose of the monitoring stations is to measure ambient concentrations of the pollutants and determine whether the ambient air quality meets the California and federal standards. The air quality monitoring station located nearest to the project site is the Perris station, located approximately 6.5 miles southeast of the project site. As referenced in Table 2, data were also obtained from the Lake Elsinore monitoring station located on West Flint approximately 13 miles southwest of the project site. Table 2 provides a summary of monitoring data at the Perris station for ozone and PM10. Nitrogen oxide and PM2.5 data from the West Flint Street monitoring station are also provided. As referenced, the SCAB is a nonattainment area for PM2.5.
As shown, both the federal and state ozone standards were exceeded at the Perris monitoring station during each of the last three years. The federal PM10 standard was not exceeded during the last three years. With respect to PM2.5, insufficient data was available to determine whether the federal or state standard was exceeded.
Air Quality Management Plan
Under state law, the SCAQMD is required to prepare a plan for air quality improvement for pollutants for which the District is in non‐compliance. The SCAQMD updates the plan every three years. Each iteration of the SCAQMD’s Air Quality Management Plan (AQMP) is an update of the previous plan and has a 20‐year horizon. SCAQMD adopted the 2016 AQMP in March 2017. The 2016 AQMP incorporates new scientific data and notable regulatory actions that have occurred since adoption of the 2012 AQMP. The 2022 AQMP is currently being developed by SCAQMD to address the EPA’s strengthened ozone standard. Development of the 2022 AQMP is in its early stages and no formal timeline for completion and adoption is currently known.

The 2016 AQMP was prepared to ensure continued progress towards clean air and comply with state and federal requirements. This AQMP builds upon the approaches taken in the 2012 AQMP for the South Coast Air Basin for the attainment of State and federal ozone air quality standards. The 2016 AQMP incorporates the 2016 Regional Transportation Plan/Sustainable Communities Strategy and updated emission inventory methodologies for applicable source categories. The 2016 AQMP also includes the new and changing federal requirements, implementation of new technology measures, and the continued development of economically sound, flexible compliance approaches. The 2016 AQMP is available to download at http://www.aqmd.gov/home/library/clean‐air‐plans/air‐quality‐mgt‐plan/final‐2016‐aqmp.
Sensitive Receptors
Sensitive receptors include, but are not limited to, hospitals, schools, daycare facilities, elderly housing and convalescent facilities. These are areas where the occupants are more susceptible to the adverse effects of exposure to air pollutants. Ambient air quality standards have been established to represent the levels of air quality considered sufficient, with an adequate margin of safety, to protect public health and welfare as well that segment of the public most susceptible to respiratory distress, such as children under 14; the elderly over 65; persons

The closest properties defined herein as sensitive receptors are single‐family residences and Monte Vista Middle School located within approximately 50 feet of the eastern and northern project boundary, respectively.
AIR QUALITY IMPACT ANALYSIS
Methodology and Significance Thresholds
This air quality analysis conforms to the methodologies recommended in the SCAQMD’s CEQA Air Quality Handbook (1993). The handbook includes thresholds for emissions associated with both construction and operation of proposed projects. All emissions were calculated using the California Emissions Estimator Model (CalEEMod) software version 2020.4.0.
Construction activities such as clearing, grading and excavation would generate diesel and dust emissions. Construction equipment that would generate criteria air pollutants includes excavators, graders, dump trucks, and loaders. To provide a conservative evaluation of construction emissions, it was assumed that all construction equipment used would be diesel‐ powered. Construction emissions associated with development of the proposed project were calculated by estimating the types of equipment (including the number) that would be used on‐ site during each of the construction phases. Construction emissions are analyzed using the regional thresholds established by the SCAQMD and published in the CEQA Air Quality Handbook.
Operational emissions include mobile source emissions, energy emissions, and area source emissions. Mobile source emissions are generated by motor vehicle trips associated with operation of the project. Emissions attributed to energy use include electricity and natural gas consumption for space and water heating. Area source emissions are generated by landscape maintenance equipment, consumer products and architectural coatings (i.e., paints). To determine whether a regional air quality impact would occur, the increase in emissions are compared with the SCAQMD’s recommended regional thresholds for operational emissions.
Projects that meet the SCAQMD daily thresholds have no significant project‐specific air quality impact and do not contribute to significant cumulative air quality impacts.
Regional Thresholds. Based on Appendix G of the CEQA Guidelines (2021), a project would have a significant air quality impact if it would:
a) Conflict with or obstruct implementation of the applicable air quality plan; b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non‐attainment under an applicable federal or state ambient air quality standard;
c) Expose sensitive receptors to substantial pollutant concentrations; d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

12 The SCAQMD has developed specific quantitative thresholds that apply to projects within the SCAB. The following significance thresholds apply to short‐term construction activities:
75 pounds per day of ROG
100 pounds per day of NOX
550 pounds per day of CO
150 pounds per day of SOx
150 pounds per day of PM10
55 pounds per day of PM2.5
The following significance thresholds apply to long‐term operational emissions:
55 pounds per day of ROG
55 pounds per day of NOX
550 pounds per day of CO
150 pounds per day of SOX
150 pounds per day of PM10
55 pounds per day of PM2.5
Construction Emissions
Project construction would generate temporary air pollutant emissions. These impacts are associated with fugitive dust (PM10 and PM2.5) and exhaust emissions from heavy construction vehicles, work crew vehicle trips in addition to ROG that would be released during the drying phase upon application of paint and other architectural coatings. Construction would generally consist of demolition, site preparation, grading, construction of the proposed buildings, paving, and architectural coating (i.e., paint) application. The project site is vacant.
This analysis assumes that 136,562 cubic yards of soil import would be required. The project would be required to comply with SCAQMD Rule 403, which identifies measures to reduce fugitive dust and is required to be implemented at all construction sites located within the South Coast Air Basin. Therefore, the following conditions, which are required to reduce fugitive dust in compliance with SCAQMD Rule 403, were included in CalEEMod for site preparation and grading phases of construction.
1. Minimization of Disturbance. Construction contractors should minimize the area disturbed by clearing, grading, earth moving, or excavation operations to prevent excessive amounts of dust.
2. Soil Treatment. Construction contractors should treat all graded and excavated material, exposed soil areas, and active portions of the construction site, including unpaved on‐site roadways to minimize fugitive dust. Treatment shall include, but not necessarily be limited to, periodic watering, application of environmentally safe soil stabilization materials,

Packet Pg. 563 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
13 and/or roll compaction as appropriate. Watering shall be done as often as necessary, and at least twice daily, preferably in the late morning and after work is done for the day.
3. Soil Stabilization. Construction contractors should monitor all graded and/or excavated inactive areas of the construction site at least weekly for dust stabilization. Soil stabilization methods, such as water and roll compaction, and environmentally safe dust control materials, shall be applied to portions of the construction site that are inactive for over four days. If no further grading or excavation operations are planned for the area, the area shall be seeded and watered until landscape growth is evident, or periodically treated with environmentally safe dust suppressants, to prevent excessive fugitive dust.
4. No Grading During High Winds. Construction contractors should stop all clearing, grading, earth moving, and excavation operations during periods of high winds (20 miles per hour or greater, as measured continuously over a one‐hour period).
5. Street Sweeping. Construction contractors should sweep all on‐site driveways and adjacent streets and roads at least once per day, preferably at the end of the day, if visible soil material is carried over to adjacent streets and roads.
Construction emissions modeling for demolition, site preparation, grading, building construction, paving, and architectural coating application is based on the overall scope of the proposed development and construction phasing which is expected to begin early 2023 and extend through late 2025. The total area disturbed as a result of the project would be 35.06 acres with construction of the residences and immediate off‐site street and stormwater Line G‐3 improvements. For modeling purposes, it was assumed the site would be watered three times daily. In addition to SCAQMD Rule 403 requirements, emissions modeling also accounts for the use of low‐VOC paint (50 g/L for non‐flat coatings) as required by SCAQMD Rule 1113. Further, the application of architectural coatings was overlapped with the building construction phase to reflect a typical construction scenario. This approach reduces daily VOC emissions relative to those calculated using CalEEMod construction phasing defaults. Table 3 summarizes the estimated maximum daily emissions of pollutants occurring during construction. As shown in Table 3, construction of the proposed project would not exceed the SCAQMD regional thresholds. No mitigation would be required with implementation of standard SCAQMD Rule 403 and Rule 1113 dust control measures.
Localized Significance Thresholds. The SCAQMD has published a “Fact Sheet for Applying CalEEMod to Localized Significance Thresholds” (South Coast Air Quality Management District 2011). CalEEMod calculates construction emissions based on the number of equipment hours and the maximum daily disturbance activity possible for each piece of equipment.
Construction‐related emissions reported by CalEEMod are compared to the localized

significance threshold lookup tables. The CalEEMod output in Appendix A shows the equipment assumed for this analysis.
LSTs were devised in response to concern regarding exposure of individuals to criteria pollutants in local communities. LSTs represent the maximum emissions from a project that will not cause or contribute to an air quality exceedance of the most stringent applicable federal or state ambient air quality standard at the nearest sensitive receptor, taking into consideration ambient concentrations in each source receptor area (SRA), project size and distance to the sensitive receptor. However, LSTs only apply to emissions within a fixed stationary location, including idling emissions during both project construction and operation. LSTs have been developed for NOX, CO, PM10 and PM2.5. LSTs are not applicable to mobile sources such as cars on a roadway (Final Localized Significance Threshold Methodology, SCAQMD, June 2003).
However, according to SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes stationary sources or attracts mobile sources that may spend long periods queuing and idling at the site such as warehouse/transfer facilities or drive‐ thru window aisles. The project does not include those uses; thus, no operational LST evaluation was performed.
LSTs have been developed for emissions within areas up to five acres in size, with air pollutant modeling recommended for activity within larger areas. The SCAQMD provides lookup tables for project sites that measure one, two, or five acres. A total of 3.5 acres is assumed to be disturbed daily during the site preparation phase and five acres would be disturbed daily during grading. To provide a conservative evaluation of potential short‐term LST impacts, the look up table values for two acres were used to provide a conservative evaluation of potential impacts during site preparation and grading. The project site is located in Source Receptor Area 28 (SRA‐28, Hemet/San Jacinto Valley). LSTs for construction related emissions in the SRA 28 at varying distances between the source and receiving property are shown in Table 4.

As referenced, the nearest sensitive receptors to the project site are located approximately 50 feet (15 meters) east of the eastern property boundary. Monte Vista Middle School is located approximately 50 feet (15 meters) north of the northern property boundary. For sensitive properties located less than 25 meters from an emission source, the 25‐meter values are used to evaluate construction emissions relative to LST thresholds as stated in Chapter 3 of the SCAQMD Final Significance Threshold Methodology (Revised July 2008). As shown in Table 5, unmitigated on‐site PM10 and PM2.5 emissions would exceed the LST thresholds shown in Table 4 at 25 meters during site preparation and grading. Thus, without mitigation, emissions would be potentially significant per thresholds (b) and (c).

Mitigation Measures AQ‐1 PM10 and PM2.5 Reduction. Contractor shall be conditioned to apply water to soils being actively disturbed during site preparation and grading activities occurring within 25 meters of the nearest residence and Monte Vista Middle School. Water shall be applied at least three times daily such that the moisture content reaches 15%. Further, during site preparation specifically, equipment use shall be limited to no more than two rubber‐tired dozers and two tractors/loaders/backhoes or like equipment, working simultaneously within 25 meters of the nearest residence and Monte Vista Middle School ball field when students are present.
Additionally, contractor shall apply soil stabilizers to unpaved on‐site roads, sweep adjacent off‐site paved roads and limit on‐site vehicle travel to 15 miles per hour to minimize tire entrainment.
Construction‐Related Toxic Air Contaminant Impacts
The greatest potential for toxic air contaminant emissions would be related to diesel particulate emissions associated with heavy equipment operations during construction of the proposed project. According to SCAQMD methodology, health effects from carcinogenic air toxics are usually described in terms of “individual cancer risk”. The California Office of Environmental Health Hazard Assessment (OEHHA) health risk guidance states that a residential receptor should be evaluated based on a 30‐year exposure period. “Individual Cancer Risk” is the likelihood that a person exposed to concentrations of toxic air contaminants over a 70‐year lifetime will contract cancer, based on the use of standard risk‐assessment methodology. Given the short‐term construction schedule, the proposed project would not result in a long‐term (i.e., 30 or 70 year) exposure to a substantial source of toxic air contaminant emissions; and thus, would not be exposed to the related individual cancer risk. Therefore, no significant short‐term toxic air contaminant impacts would occur during construction of the proposed project.
Construction‐Related Odor Impacts
Potential sources of odor during construction activities include equipment exhaust and activities such as paving. The objectionable odors that may be produced during the construction process would occur periodically and end when construction is completed. No significant impact related to odors would occur during construction of the proposed project per threshold (d) referenced above.

17 Long‐Term Regional Impacts
Regional Pollutant Emissions
Table 6 summarizes emissions associated with operation of the proposed project. Operational emissions include emissions from electricity consumption (energy sources), vehicle trips (mobile sources), and area sources including landscape equipment and architectural coating emissions as the structures are repainted over the life of the project. The majority of operational emissions are associated with vehicle trips to and from the project site. Trip volumes based on trip generation defaults for the uses comprising the project were modified based on trip generation rates in the Traffic Impact Assessment prepared for the proposed project by TJW Engineering, Inc., June 2021.
Area source emissions from the project include stationary combustion emissions of natural gas used for space and water heating (shown in a separate row as energy), yard and landscape maintenance, consumer use of solvents and personal care products, and an average building square footage to be repainted each year. As shown in Table 6, daily unmitigated emissions would not exceed the SCAQMD thresholds for ROG, NOX, CO, SOX, PM10 or PM2.5. Therefore, the project’s regional air quality impacts (including impacts related to criteria pollutants, sensitive receptors and violations of air quality standards) would be less than significant per threshold b. Further, because the project would meet SCAQMD daily thresholds, the project would not contribute to a cumulatively considerable impact. Impacts relative to threshold c would be less than significant.

18 composting operations, landfills and dairies. Residential uses are not associated with activities that generate odors. Odors would be less than significant per threshold (d).
AQMP Consistency
A project may be inconsistent with the AQMP if it would generate population, housing, or employment growth exceeding forecasts used in the development of the AQMP. The 2016 AQMP, the most recent AQMP adopted by the SCAQMD, incorporates local city General Plans and the Southern California Association of Government’s (SCAG) Regional Transportation Plan socioeconomic forecast projections of regional population, housing and employment growth.
The proposed project involves the construction of 181 single‐family residential units and related improvements. The proposed project would be consistent with the existing zoning and existing residential uses surrounding the site. Vehicle trips associated with the project would be consistent with similar uses in the area and as discussed herein, project‐related emissions would not exceed thresholds recommended by the SCAQMD. Thus, the project would be consistent with the AQMP and not cause an adverse impact under threshold (a).
Friant Ranch Case Overview and Project Applicability
In response to the California Supreme Court decision on December 24, 2018, Sierra Club v.
County of Fresno (Friant Ranch), this section provides a discussion on the potential for identifiable health impacts to result from air pollutants analyzed in environmental documents prepared pursuant to the California Environmental Quality Act (CEQA). The discussion focuses on significant impacts and the feasibility of directly relating any identified significant adverse air quality impact to likely health consequences. The Supreme Court opinion in Friant Ranch requires projects with significant air quality impacts to relate the expected adverse air quality impacts to likely health consequences or explain why it is not feasible at the time of drafting to provide such an analysis, so that the public may make informed decisions regarding the costs and benefits of the project.
The purpose of CEQA is to inform the public as to the potential for a proposed project to result in one or more significant adverse effects on the environment (including health effects). This includes the potential for a project to result in a considerable contribution towards one or more significant cumulative impacts. CEQA does not require detailed analysis of impacts that are found to be less than significant or less than a considerable contribution to a significant cumulative impact. In accordance with CEQA requirements and the CEQA review process, air quality impacts associated with proposed local plans and development projects, requires mitigation of potentially significant air quality impacts by conditioning discretionary permits, and monitors and enforces implementation of such mitigation. The State CEQA Guidelines Section 15064.7 states that the significance criteria established by the applicable air quality management district or air pollution control district, when available, may be relied upon to make determinations of significance.

19 As stated, the project is located within the SCAB under the jurisdiction of the SCAQMD. The City of San Jacinto defers to threshold guidance established by the SCAQMD and utilizes the SCAQMD’s CEQA Air Quality Handbook (approved by the AQMD Governing Board in 1993) and subsequent guidance provided on the SCAQMD website. Note the SCAQMD is currently in the process of developing an Air Quality Analysis Guidance Handbook to replace the 1993 Handbook. In addition, when considering potential air quality impacts under CEQA, consideration is given to the location of sensitive receptors within proximity to land uses that emit TACs. CARB has published and adopted the Air Quality and Land Use Handbook: A Community Health Perspective (2005), which considers impacts to sensitive receptors from facilities that emit TAC emissions. CARB has also published Strategies to Reduce Air Pollution Exposure Near High‐Volume Roadways: Technical Advisory, a supplement to the handbook that is intended to provide scientifically based strategies to reduce exposure to traffic emissions near high‐volume roadways to protect public health and promote equity and environmental justice. The SCAQMD has also adopted land use planning guidelines in the Guidance Document for Addressing Air Quality Issues in General Plans and Local Planning (2005).
Together, the documents introduce land use‐related policies and strategies that rely on design and distance parameters to minimize emissions and lower potential health risks.
Federal and state ambient air quality standards are designed to prevent the harmful effects of air pollution. These standards are continually updated based on evolving research, including research which relates air quality impacts with health effects. At the regional level, plans such as the SCAQMD’s AQMP and SCAG’s RTP/SCS work to ensure that the South Coast Air Basin reaches and maintains attainment with these federal and state standards. At the local level, environmental documents evaluate a plan or project’s consistency with applicable policies identified in the SCAQMD’s AQMP and SCAG’s RTP/SCS as well as regulatory compliance measures which work to limit risk and exposure to TACs. In addition, when evaluating air quality impacts at the project‐level, the City of San Jacinto utilizes thresholds guidance and air quality models established by the SCAQMD, which have been developed to implement these regional plans for attainment and protection of public health. For local projects that exceed any identified SCAQMD air quality threshold, CEQA documents typically identify and disclose generalized health effects of certain air pollutants but are currently unable to establish a reliable connection between any local plan or project and a particular health effect. In addition, no expert agency has yet to approve a quantitative method to reliably and meaningfully do so.
Many factors contribute to this uncertainty, including the regional scope of air quality monitoring and planning, technological limitations for modeling at a local plan‐ or project‐level, and the intrinsically complex nature between air pollutants and health effects in conjunction with local environmental variables. Therefore, at the time, it is infeasible for CEQA documents to directly link a project’s significant air quality impacts with a specific health effect. However, as air quality modeling and research on health effects advances over time, the County will continue to seek the latest guidance from local air quality agencies and experts and refine its approach based on future information as it becomes available.

GREENHOUSE GAS EMISSION DISCUSSION
Gases that absorb and re‐emit infrared radiation in the atmosphere are called greenhouse gases (GHGs). GHGs are present in the atmosphere naturally, are released by natural sources, or are formed from secondary reactions taking place in the atmosphere. The gases that are widely seen as the principal contributors to human‐induced climate change include carbon dioxide (CO2), methane (CH4), nitrous oxides (N2O), fluorinated gases such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Water vapor is excluded from the list of GHGs because it is short‐lived in the atmosphere and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation.
GHGs are emitted by both natural processes and human activities. Of these gases, CO2 and CH4 are emitted in the greatest quantities from human activities. Emissions of CO2 are largely by‐products of fossil fuel combustion, whereas CH4 results from off‐gassing associated with agricultural practices and landfills. Man‐made GHGs, many of which have greater heat‐absorption potential than CO2, include fluorinated gases and sulfur hexafluoride (SF6) (California Environmental Protection Agency [CalEPA], 2006). Different types of GHGs have varying global warming potentials (GWPs). The GWP of a GHG is the potential of a gas or aerosol to trap heat in the atmosphere over a specified timescale (generally, 100 years). Because GHGs absorb different amounts of heat, a common reference gas (CO2) is used to relate the amount of heat absorbed to the amount of the gas emissions, referred to as “carbon dioxide equivalent” (CO2E), and is the amount of a GHG emitted multiplied by its GWP. Carbon dioxide has a GWP of one. By contrast, methane (CH4) has a GWP of 28, meaning its global warming effect is 28 times greater than carbon dioxide on a molecule per molecule basis (IPCC, 2014).
Total U.S. GHG emissions were 6,558 MMT CO2E in 2019 (U.S. EPA, October 2021). Total U.S. emissions decreased from 2018 to 2019 by 1.7 percent primarily as a result of less fossil fuel combustion. Total U.S. emissions have increased by 2.0 percent from 1990 to 2019, down from a high of 15.7 percent above 1990 levels in 2007. Emissions decreased from 2018 to 2019 by 1.7 percent (116.0 MMT CO2e). Net emissions (including sinks) were 5,769 MMT CO2e. Overall, net emissions decreased 1.7 percent from 2018 to 2019 and decreased 12.9 percent from 2005 levels.
The decline reflects many long‐term trends, including population, economic growth, energy market trends, technological changes including energy efficiency and carbon intensity of energy fuel choices. Between 2018 and 2019, the decrease in total greenhouse gas emissions was largely driven by the decrease in CO2 emissions from fossil fuel combustion. The decrease in CO2 emissions from fossil fuel combustion was a result of a 1.3 percent decrease in total energy use and reflects a continued shift from coal to less carbon intensive natural gas and renewables. (U.S. EPA, February 2021).

21 In 2018, statewide emissions from GHG emitting activities statewide were 425 million metric tons of carbon dioxide equivalent (MMTCO2e), 0.8 MMTCO2e higher than 2017 levels and 6 MMTCO2e below the 2020 GHG Limit of 431 MMTCO2e. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then. Transportation emissions decreased in 2018 compared to the previous year, which is the first year over year decrease since 2013. Since 2008, California’s electricity sector has followed an overall downward trend in emissions. In 2018, solar power generation has continued to grow. Emissions from high‐GWP gases increased 2.3 percent in 2018 (2000‐2018 average year‐over year increase is 6.8 percent), continuing the increasing trend as Ozone Depleting Substances (ODS) are phased out under the 1987 Montreal Protocol.
The largest source of GHG in California is transportation, contributing 39.9 percent of the state’s total GHG emissions. The industrial sector is the second largest source, contributing 21 percent of the state’s GHG emissions. California emissions result in part to its geographic size and large population compared to other states. However, a factor that reduces California’s per capita fuel use and GHG emissions, as compared to other states, is its relatively mild climate. In July 2017, California’s state legislature passed Assembly Bill (AB) 398 to reauthorize and extend until 2030 the state’s economy‐wide greenhouse gas (GHG) reduction program. The bill sets a new GHG target of at least 40% below the 1990 level of emissions by 2030.
California Regulations
In 2005, former Governor Schwarzenegger issued Executive Order (EO) S‐3‐05, establishing statewide GHG emissions reduction targets. EO S‐3‐05 states that by 2020, emissions shall be reduced to 1990 levels; and by 2050, emissions shall be reduced to 80 percent of 1990 levels (CalEPA, 2006). In response to EO S‐3‐05, CalEPA created the Climate Action Team (CAT), which in March 2006 published the Climate Action Team Report (the “2006 CAT Report”) (CalEPA, 2006). The 2006 CAT Report recommended various strategies that the state could pursue to reduce GHG emissions. These strategies could be implemented by various state agencies to ensure that the emission reduction targets in EO S‐3‐05 are met and can be met with existing authority of the state agencies. The strategies include the reduction of passenger and light duty truck emissions, the reduction of idling times for diesel trucks, an overhaul of shipping technology/infrastructure, increased use of alternative fuels, increased recycling, and landfill methane capture.
Assembly Bill 32 and CARB’s Scoping Plan
To further the goals established in EO S‐3‐05, the Legislature passed Assembly Bill (AB) 32, the California Global Warming Solutions Act of 2006. AB 32 requires California to reduce its GHG emissions to 1990 levels by 2020. Under AB 32, CARB is responsible for and is recognized as having the expertise to carry out and develop the programs and requirements necessary to achieve the GHG emissions reduction mandate of AB 32. Under AB 32, CARB must adopt regulations requiring the reporting and verification of statewide GHG emissions from specified sources. This program is used to monitor and enforce compliance with established standards.
CARB also is required to adopt rules and regulations to achieve the maximum technologically

Packet Pg. 572 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
22 feasible and cost‐effective GHG emission reductions. AB 32 authorized CARB to adopt market‐ based compliance mechanisms to meet the specified requirements. Finally, CARB is ultimately responsible for monitoring compliance and enforcing any rule, regulation, order, emission limitation, emission reduction measure, or market‐based compliance mechanism adopted.
In 2007, CARB approved a limit on the statewide GHG emissions level for year 2020 consistent with the determined 1990 baseline (427 MMT CO2E). CARB’s adoption of this limit is in accordance with Health and Safety Code, Section 38550.
Further, in 2008, CARB adopted the Scoping Plan in accordance with Health and Safety Code, Section 38561. The Scoping Plan establishes an overall framework for the measures that will be adopted to reduce California’s GHG emissions for various emission sources/sectors to 1990 levels by 2020. The Scoping Plan evaluates opportunities for sector‐specific reductions, integrates all CARB and Climate Action Team early actions and additional GHG reduction features by both entities, identifies additional measures to be pursued as regulations, and outlines the role of a cap‐and‐trade program. The key elements of the Scoping Plan include the following (CARB 2008):
1. Expanding and strengthening existing energy efficiency programs, as well as building and appliance standards;
2. Achieving a statewide renewable energy mix of 33%;
3. Developing a California cap‐and‐trade program that links with other Western Climate Initiative partner programs to create a regional market system and caps sources contributing 85% of California’s GHG emissions;
4. Establishing targets for transportation‐related GHG emissions for regions throughout California, and pursuing policies and incentives to achieve those targets;
5. Adopting and implementing measures pursuant to existing state laws and policies, including California’s clean car standards, goods movement measures, and the Low Carbon Fuel Standard; and
6. Creating targeted fees, including a public goods charge on water use, fees on high GWP gases, and a fee to fund the administrative costs of the State of California’s long‐term commitment to AB 32 implementation.
In the Scoping Plan (CARB 2008), CARB determined that achieving the 1990 emissions level in 2020 would require a reduction in GHG emissions of approximately 28.5% from the otherwise projected 2020 emissions level (i.e., those emissions that would occur in 2020) absent GHG reducing laws and regulations (referred to as Business‐As‐Usual (BAU)). To calculate this percentage reduction, CARB assumed that all new electricity generation would be supplied by natural gas plants, no further regulatory action would impact vehicle fuel efficiency, and building energy efficiency codes would be held at 2005 standards.
In the 2011 Final Supplement to the AB 32 Scoping Plan Functional Equivalent Document (CARB 2011a), CARB revised its estimates of the projected 2020 emissions level in light of the economic recession and the availability of updated information about GHG reduction
4.1.l

23 regulations. Based on the new economic data, CARB determined that achieving the 1990 emissions level by 2020 would require a reduction in GHG emissions of 21.7% (down from
28.5%) from the BAU conditions. When the 2020 emissions level projection was updated to account for newly implemented regulatory measures, including Pavley I (model years 2009– 2016) and the Renewables Portfolio Standard (RPS) (12% to 20%), CARB determined that achieving the 1990 emissions level in 2020 would require a reduction in GHG emissions of 16% (down from 28.5%) from the BAU conditions.
In 2014, CARB adopted the First Update to the Climate Change Scoping Plan: Building on the Framework (First Update; CARB 2014). The stated purpose of the First Update is to “highlight California’s success to date in reducing its GHG emissions and lay the foundation for establishing a broad framework for continued emission reductions beyond 2020, on the path to 80% below 1990 levels by 2050” (CARB 2014). The First Update found that California is on track to meet the 2020 emissions reduction mandate established by AB 32 and noted that California could reduce emissions further by 2030 to levels needed to stay on track to reduce emissions to 80% below 1990 levels by 2050 if the state realizes the expected benefits of existing policy goals.
In conjunction with the First Update, CARB identified “six key focus areas comprising major components of the state’s economy to evaluate and describe the larger transformative actions that will be needed to meet the state’s more expansive emission reduction needs by 2050” (CARB 2014). Those six areas are (1) energy, (2) transportation (vehicles/equipment, sustainable communities, housing, fuels, and infrastructure), (3) agriculture, (4) water, (5) waste management, and (6) natural and working lands. The First Update identifies key recommended actions for each sector that will facilitate achievement of EO S‐3‐05’s 2050 reduction goal (CARB 2014).
Based on CARB’s research efforts presented in the First Update, it has a “strong sense of the mix of technologies needed to reduce emissions through 2050” (CARB 2014). Those technologies include energy demand reduction through efficiency and activity changes; large‐scale electrification of on‐road vehicles, buildings, and industrial machinery; decarbonizing electricity and fuel supplies; and the rapid market penetration of efficient and clean energy technologies.
As part of the First Update, CARB recalculated the state’s 1990 emissions level using more recent GWPs identified by the IPCC. Using the recalculated 1990 emissions level (431 MMT CO2E) and the revised 2020‐emissions‐level projection identified in the 2011 Final Supplement, CARB determined that achieving the 1990 emissions level by 2020 would require a reduction in GHG emissions of approximately 15% (instead of 28.5% or 16%) from the BAU conditions (CARB 2014).
In January 2017, CARB released, The 2017 Climate Change Scoping Plan Update (Second Update; CARB 2017b), for public review and comment. This update proposes CARB’s strategy for achieving the state’s 2030 GHG target as established in Senate Bill (SB) 32 (discussed below), including continuing the Cap‐and‐Trade Program through 2030, and includes a new approach to reduce GHGs from refineries by 20%. The Second Update incorporates approaches to cutting short‐lived climate pollutants (SLCPs) under the Short‐Lived Climate Pollutant Reduction

24 Strategy (a planning document that was adopted by CARB in March 2017), acknowledges the need for reducing emissions in agriculture, and highlights the work underway to ensure that California’s natural and working lands increasingly sequester carbon. During development of the Second Update, CARB held a number of public workshops in the Natural and Working Lands, Agriculture, Energy, and Transportation sectors to inform development of the 2030 Scoping Plan Update (CARB 2016). The Second Update has not been considered by CARB’s Governing Board at the time this analysis was prepared.
Executive Order S‐01‐07 was enacted on January 18, 2007. The order mandates that a Low Carbon Fuel Standard (“LCFS”) for transportation fuels be established for California to reduce the carbon intensity of California’s transportation fuels by at least 10 percent by 2020.
Other regulations affecting state and local GHG planning and policy development are summarized as follows:
Assembly Bill 939 and Senate Bill 1374
Assembly Bill 939 (AB 939) requires that each jurisdiction in California to divert at least 50 percent of its waste away from landfills, whether through waste reduction, recycling or other means. Senate Bill 1374 (SB 1374) requires the California Integrated Waste Management Board to adopt a model ordinance by March 1, 2004 suitable for adoption by any local agency to require 50 to 75 percent diversion of construction and demolition of waste materials from landfills.
Senate Bill 1368
Senate Bill 1368 (SB 1368) is the companion Bill of AB 32 and was adopted September, 2006. SB 1368 required the California Public Utilities Commission (CPUC) to establish a performance standard for baseload generation of GHG emissions by investor‐owned utilities by February 1, 2007 and for local publicly owned utilities by June 30, 2007. These standards could not exceed the GHG emissions rate from a baseload combined‐cycle, natural gas‐fired plant. Furthermore, the legislation states that all electricity provided to the State, including imported electricity, must be generated by plants that meet the standards set by California Public Utilities Commission (CPUC) and California Energy Commission (CEC).
Senate Bill 97
Senate Bill 97 (SB 97) was adopted August 2007 and acknowledges that climate change is an environmental issue that requires analysis under CEQA. SB 97 directed the Governor’s Office of Planning and Research (OPR), which is part of the State Natural Resources Agency, to prepare, develop, and transmit to CARB guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions, as required by CEQA, by July 1, 2009. The Natural Resources Agency was required to certify and adopt those guidelines by January 1, 2010. Pursuant to the requirements of SB 97 as stated above, on December 30, 2009 the Natural Resources Agency adopted amendments to the state CEQA guidelines that address GHG emissions. The CEQA Guidelines Amendments changed sections of the CEQA Guidelines and incorporated GHG language throughout the Guidelines. However, no GHG emissions thresholds of significance

25 were provided and no specific mitigation measures were identified. The GHG emission reduction amendments went into effect on March 18, 2010 and are summarized below:
Climate action plans and other greenhouse gas reduction plans can be used to determine whether a project has significant impacts, based upon its compliance with the plan. Local governments are encouraged to quantify the greenhouse gas emissions of proposed projects, noting that they have the freedom to select the models and methodologies that best meet their needs and circumstances. The section also recommends consideration of several qualitative factors that may be used in the determination of significance, such as the extent to which the given project complies with state, regional, or local GHG reduction plans and policies. OPR does not set or dictate specific thresholds of significance. Consistent with existing CEQA Guidelines, OPR encourages local governments to develop and publish their own thresholds of significance for GHG impacts assessment.
When creating their own thresholds of significance, local governments may consider the thresholds of significance adopted or recommended by other public agencies, or recommended by experts.
New amendments include guidelines for determining methods to mitigate the effects of greenhouse gas emissions in Appendix F of the CEQA Guidelines. OPR is clear to state that “to qualify as mitigation, specific measures from an existing plan must be identified and incorporated into the project; general compliance with a plan, by itself, is not mitigation.”
OPR’s emphasizes the advantages of analyzing GHG impacts on an institutional, programmatic level. OPR therefore approves tiering of environmental analyses and highlights some benefits of such an approach.
Environmental impact reports (EIRs) must specifically consider a projectʹs energy use and energy efficiency potential.
Senate Bills 1078, 107, and X1‐2 and Executive Orders S‐14‐08 and S‐21‐09 Senate Bill 1078 (SB 1078) requires retail sellers of electricity, including investor‐owned utilities and community choice aggregators, to provide at least 20 percent of their supply from renewable sources by 2017. Senate Bill 107 (SB 107) changed the target date to 2010. Executive Order S‐14‐08 was signed on November 2008 and expands the State’s Renewable Energy Standard to 33 percent renewable energy by 2020. Executive Order S‐21‐09 directed CARB to adopt regulations by July 31, 2010 to enforce S‐14‐08. Senate Bill X1‐2 codifies the 33 percent renewable energy requirement by 2020.

26 California Code of Regulations (CCR) Title 24, Part 6 CCR Title 24, Part 6: California’s Energy Efficiency Standards for Residential and Nonresidential Buildings (Title 24) were first established in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods. Although it was not originally intended to reduce GHG emissions, electricity production by fossil fuels results in GHG emissions and energy efficient buildings require less electricity. Therefore, increased energy efficiency results in decreased GHG emissions.
The Energy Commission adopted 2008 Standards on April 23, 2008 and Building Standards Commission approved them for publication on September 11, 2008. These updates became effective on August 1, 2009. All buildings for which an application for a building permit is submitted on or after July 1, 2014 must follow the 2013 standards. The 2013 commercial standards are estimated to be 30 percent more efficient than the 2008 standards; 2013 residential standards are at least 25 percent more efficient. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases greenhouse gas emissions.
Senate Bill 375
Senate Bill 375 (SB 375) was adopted in September 2008 and aligns regional transportation planning efforts, regional GHG emission reduction targets, and land use and housing allocation.
SB 375 requires Metropolitan Planning Organizations (MPO) to adopt a sustainable communities strategy (SCS) or alternate planning strategy (APS) that will prescribe land use allocation in that MPOs Regional Transportation Plan (RTP). CARB, in consultation with each MPO, will provide each affected region with reduction targets for GHGs emitted by passenger cars and light trucks in the region for the years 2020 and 2035. These reduction targets will be updated every eight years but can be updated every four years if advancements in emissions technologies affect the reduction strategies to achieve the targets. CARB is also charged with reviewing each MPO’s sustainable community’s strategy or alternate planning strategy for consistency with its assigned targets.
The proposed project is located within the Southern California Association of Governments (SCAG) jurisdiction, which has authority to develop the SCS or APS. For the SCAG region, beginning October 2018, the targets set by CARB are at eight percent below 2005 per capita GHG emissions levels by 2020 and 19 percent below 2005 per capita GHG emissions levels by 2035. On September 3, 2020, SCAG adopted the 2020‐2045 Regional Transportation Plan / Sustainable Communities Strategy (RTP/SCS), Connect SoCal. which meets the CARB emission reduction requirements. The Housing Element Update is required by the State to be completed within 18 months after RTP/SCS adoption. The Riverside County Housing Element 2021‐2029 (6th Cycle) is being prepared and will include housing‐related goals, policies, and programs to address the existing and projected future housing needs of the unincorporated County.
City and County land use policies, including General Plans, are not required to be consistent with the RTP and associated SCS or APS. However, CEQA incentivizes, through streamlining

27 and other provisions, qualified projects that are consistent with an approved SCS or APS and categorized as “transit priority projects.”
Senate Bill X7‐7
Senate Bill X7‐7 (SB X7‐7), enacted on November 9, 2009, mandates water conservation targets and efficiency improvements for urban and agricultural water suppliers. SB X7‐7 requires the Department of Water Resources (DWR) to develop a task force and technical panel to develop alternative best management practices for the water sector. Additionally, SB X7‐7 required the DWR to develop criteria for baseline uses for residential, commercial, and industrial uses for both indoor and landscaped area uses. The DWR was also required to develop targets and regulations that achieve a statewide 20 percent reduction in water usage.
California Green Building Standards
Title 24, Part 6. Title 24 of the California Code of Regulations was established in 1978 and serves to enhance and regulate California’s building standards. While not initially promulgated to reduce GHG emissions, Part 6 of Title 24 specifically establishes Building Energy Efficiency Standards that are designed to ensure new and existing buildings in California achieve energy efficiency and preserve outdoor and indoor environmental quality. These energy efficiency standards are reviewed every few years by the Building Standards Commission and the California Energy Commission (CEC) (and revised if necessary) (California Public Resources Code, Section 25402(b)(1)). The regulations receive input from members of industry, as well as the public, with the goal of “reducing of wasteful, uneconomic, inefficient, or unnecessary consumption of energy” (California Public Resources Code, Section 25402). These regulations are carefully scrutinized and analyzed for technological and economic feasibility (California Public Resources Code, Section 25402(d)) and cost effectiveness (California Public Resources Code, Sections 25402(b)(2) and (b)(3)). These standards are updated to consider and incorporate new energy efficient technologies and construction methods. As a result, these standards save energy, increase electricity supply reliability, increase indoor comfort, avoid the need to construct new power plants, and help preserve the environment.
The 2019 Title 24 building energy efficiency standards and became effective on January 1, 2020.
In general, single‐family homes built to the 2019 standards are anticipated to use approximately 7% less energy for lighting, heating, cooling, ventilation, and water heating than those built to the 2016 standards, and nonresidential buildings built to the 2019 standards will use an estimated 30% less energy than those built to the 2016 standards (CEC 2015a).
Title 24, Part 11. In addition to the CEC’s efforts, in 2008, the California Building Standards Commission adopted the nation’s first green building standards. The California Green Building Standards Code (Part 11 of Title 24) is commonly referred to as “CALGreen,” and establishes minimum mandatory standards and voluntary standards pertaining to the planning and design of sustainable site development, energy efficiency (in excess of the California Energy Code requirements), water conservation, material conservation, and interior air quality. The CALGreen standards took effect in January 2011 and instituted mandatory minimum environmental performance standards for all ground‐up, new construction of commercial, low‐

Packet Pg. 578 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
28 rise residential, and state‐owned buildings and schools and hospitals. The CALGreen 2019 standards became effective on January 1, 2020. The mandatory standards require the following (24 CCR Part 11):
• Mandatory reduction in indoor water use through compliance with specified flow rates for plumbing fixtures and fittings;
• Mandatory reduction in outdoor water use through compliance with a local water efficient landscaping ordinance or the California Department of Water Resources’ Model Water Efficient Landscape Ordinance;
• Diversion of 65% of construction and demolition waste from landfills; • Mandatory inspections of energy systems to ensure optimal working efficiency; • Inclusion of electric vehicle charging stations or designated spaces capable of supporting future charging stations; and
• Low‐pollutant‐emitting exterior and interiorfinish materials, such as paints, carpets, vinyl flooring, and particle board.
The CALGreen standards also include voluntary efficiency measures that are provided at two separate tiers and implemented at the discretion of local agencies and applicants. CALGreen’s Tier 1 standards call for a 15% improvement in energy requirements, stricter water conservation, 65% diversion of construction and demolition waste, 10% recycled content in building materials, 20% permeable paving, 20% cement reduction, and cool/solar‐reflective roofs. CALGreen’s more rigorous Tier 2 standards call for a 30% improvement in energy requirements, stricter water conservation, 75% diversion of construction and demolition waste, 15% recycled content in building materials, 30% permeable paving, 25% cement reduction, and cool/solar‐reflective roofs (24 CCR Part 11).
The California Public Utilities Commission, CEC, and CARB also have a shared, established goal of achieving zero net energy (ZNE) for new construction in California. The key policy timelines include the following: (1) all new residential construction in California will be ZNE by 2020, and (2) all new commercial construction in California will be ZNE by 2030 (CPUC 2013).2 As most recently defined by the CEC in its 2015 Integrated Energy Policy Report (CEC 2015b), a ZNE code building is “one where the value of the energy produced by on‐site renewable energy resources is equal to the value of the energy consumed annually by the building” using the CEC’s Time Dependent Valuation metric.
Title 20
Title 20 of the California Code of Regulations requires manufacturers of appliances to meet state and federal standards for energy and water efficiency. Performance of appliances must be certified through the CEC to demonstrate compliance with standards. New appliances regulated under Title 20 include refrigerators, refrigerator‐freezers, and freezers; room air conditioners and room air‐conditioning heat pumps; central air conditioners; spot air 2 It is expected that achievement of the ZNE goal will occur through revisions to the Title 24 standards.

29 conditioners; vented gas space heaters; gas pool heaters; plumbing fittings and plumbing fixtures; fluorescent lamp ballasts; lamps; emergency lighting; traffic signal modules; dishwaters; clothes washers and dryers; cooking products; electric motors; low voltage dry‐type distribution transformers; power supplies; televisions and consumer audio and video equipment; and battery charger systems. Title 20 presents protocols for testing for each type of appliance covered under the regulations and appliances must meet the standards for energy performance, energy design, water performance, and water design. Title 20 contains three types of standards for appliances: federal and state standards for federally regulated appliances, state standards for federally regulated appliances, and state standards for non‐federally regulated appliances.
Executive Order B‐30‐15
EO B‐30‐15 (April 2015) identified an interim GHG reduction target in support of targets previously identified under S‐3‐05 and AB 32. EO B‐30‐15 set an interim target goal of reducing statewide GHG emissions to 40% below 1990 levels by 2030 to keep California on its trajectory toward meeting or exceeding the long‐term goal of reducing statewide GHG emissions to 80% below 1990 levels by 2050 as set forth in EO S‐3‐05. To facilitate achievement of this goal, EO B‐ 30‐15 calls for an update to CARB’s Scoping Plan to express the 2030 target in terms of MMT CO2E. EO B‐30‐15 also calls for state agencies to continue to develop and implement GHG emission reduction programs in support of the reduction targets. EO B‐30‐15 does not require local agencies to take any action to meet the new interim GHG reduction target.
Senate Bill 32 and Assembly Bill 197
SB 32 and AB 197 (enacted in 2016) are companion bills that set new statewide GHG reduction targets, make changes to CARB’s membership, increase legislative oversight of CARB’s climate change–based activities, and expand dissemination of GHG and other air quality–related emissions data to enhance transparency and accountability. More specifically, SB 32 codified the 2030 emissions reduction goal of EO B‐30‐15 by requiring CARB to ensure that statewide GHG emissions are reduced to 40% below 1990 levels by 2030. AB 197 established the Joint Legislative Committee on Climate Change Policies, consisting of at least three members of the Senate and three members of the Assembly, in order to provide ongoing oversight over implementation of the state’s climate policies. AB 197 added two members of the Legislature to CARB as nonvoting members; requires CARB to make available and update (at least annually via its website) emissions data for GHGs, criteria air pollutants, and toxic air contaminants from reporting facilities; and requires CARB to identify specific information for GHG emissions reduction measures when updating the Scoping Plan.
SB 350— Clean Energy and Pollution Reduction Act of 2015 In October 2015, the legislature approved and the Governor signed SB 350, which reaffirms California’s commitment to reducing its GHG emissions and addressing climate change. Key provisions include an increase in the renewables portfolio standard (RPS), higher energy efficiency requirements for buildings, initial strategies towards a regional electricity grid, and improved infrastructure for electric vehicle charging stations. Provisions for a 50 percent reduction in the use of petroleum statewide were removed from the Bill because of opposition

30 and concern that it would prevent the Bill’s passage. Specifically, SB 350 requires the following to reduce statewide GHG emissions:
Increase the amount of electricity procured from renewable energy sources from 33 percent to 50 percent by 2030, with interim targets of 40 percent by 2024, and 25 percent by 2027.
Double the energy efficiency in existing buildings by 2030. This target will be achieved through the California Public Utility Commission (CPUC), the California Energy Commission (CEC), and local publicly‐owned utilities.
Reorganize the Independent System Operator (ISO) to develop more regional electrify transmission markets and to improve accessibility in these markets, which will facilitate the growth of renewable energy markets in the western United States (California Leginfo 2015).
SB 100
On September 10, 2018, Governor Brown signed SB 100, which raises California’s RPS requirements to 60 percent by 2030, with interim targets, and 100 percent by 2045. The bill also establishes a state policy that eligible renewable energy resources and zero‐carbon resources supply 100 percent of all retail sales of electricity to California end‐use customers and 100 percent of electricity procured to serve all state agencies by December 31, 2045. Under the bill, the state cannot increase carbon emissions elsewhere in the western grid or allow resource shuffling to achieve the 100 percent carbon‐free electricity target.
Executive Order B‐55‐18
On September 10, 2018, Governor Brown signed Executive Order B‐55‐2018 which established a new statewide goal to achieve carbon neutrality as soon as possible and no later than 2045. The executive order also states that California will achieve and maintain net negative emissions thereafter.
AB 2127
AB 2127 promotes better planning for EV infrastructure build‐out across all vehicle classes. AB 2127 would help the state meet the goal of 5 million zero‐emission vehicles (ZEV) on the road by 2030.
Local Regulations and CEQA Requirements
As referenced, pursuant to the requirements of SB 97, the Resources Agency has adopted amendments to the State CEQA Guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions. The adopted CEQA Guidelines provide general regulatory guidance on the analysis and mitigation of GHG emissions in CEQA documents, but contain no suggested thresholds of significance for GHG emissions. Instead, lead agencies are given the discretion to set quantitative or qualitative thresholds for the assessment and mitigation of GHGs and climate change impacts. The general approach to developing a Threshold of Significance for GHG
4.1.l
Packet Pg. 581 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
31 emissions is to identify the emissions level for which a project would not be expected to substantially conflict with existing California legislation adopted to reduce statewide GHG emissions needed to move the state towards climate stabilization. If a project would generate GHG emissions above the threshold level, its contribution to cumulative impacts would be considered significant. To date, the Bay Area Air Quality Management District (BAAQMD), the South Coast Air Quality Management District (SCAQMD), and the San Joaquin Air Pollution Control District (SJVAPCD) have adopted quantitative significance thresholds for GHGs. However, in March 2013 the Bay Area’s thresholds were overruled by the Alameda County Superior Court (California Building Industry Association v. Bay Area Air Quality Management District), on the basis that adoption of the thresholds constitutes a “project” under CEQA, but did not receive the appropriate environmental review. As a result, BAAQMD has elected to not recommend specific GHG thresholds for use in CEQA documents.
The SCAQMD threshold, which was adopted in December 2008, considers emissions of over 10,000 metric tons CO2E /year to be significant. However, the SCAQMD’s threshold applies only to stationary sources and is expressly intended to apply only when the SCAQMD is the CEQA lead agency. Although not formally adopted, the SCAQMD has developed a draft quantitative threshold for all land use types of 3,000 metric tons CO2E /year (SCAQMD, September 2010). Note that lead agencies retain the responsibility to determine significance on a case‐by‐case basis for each specific project.
CLIMATE CHANGE IMPACT ANALYSIS
Thresholds of Significance
Pursuant to the requirements of SB 97, the Resources Agency adopted amendments to the State CEQA Guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions in March 2010. These guidelines are used in evaluating the cumulative significance of GHG emissions from the proposed project. According to the adopted CEQA Guidelines, impacts related to GHG emissions from the proposed project would be significant if the project would:
Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment; and/or
Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases.
The vast majority of individual projects do not generate sufficient GHG emissions to create a project‐specific impact through a direct influence to climate change; therefore, the issue of climate change typically involves an analysis of whether a project’s contribution towards an impact is cumulatively considerable. “Cumulatively considerable” means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, other current projects, and probable future projects (CEQA Guidelines, Section 15355).

Packet Pg. 582 Attachment: Appendix A - Air Quality Greenhouse Study (JA Bray Community T38202 (P21-076)) San Jacinto Residential TTM 38202 Air Quality and Greenhouse Gas Study City of San Jacinto
32 For future projects, the significance of GHG emissions may be evaluated based on locally adopted quantitative thresholds, or consistency with a regional GHG reduction plan (such as a Climate Action Plan). The City of San Jacinto does not have a Climate Action Plan; thus, the proposed project is evaluated herein based on 3,000 MT CO2e significance standard. To determine whether GHG emissions associated with the proposed project are “cumulatively considerable,” consistency with applicable GHG emissions reductions strategies recommended in EO S‐3‐05 and SB 32.
Methodology
GHG emissions associated with construction and operation of the proposed project have been estimated using California Emissions Estimator Model (CalEEMod) version 2020.4.0.
Construction Emissions
Construction of the proposed project would generate temporary GHG emissions primarily associated with the operation of construction equipment and truck trips. Site preparation and grading typically generate the greatest emission quantities because the use of heavy equipment is greatest during this phase of construction. Emissions associated with the construction period were estimated based on the projected maximum amount of equipment that would be used on‐ site at one time. Air districts such as the SCAQMD have recommended amortizing construction‐ related emissions over a 30‐year period to calculate annual emissions. Complete CalEEMod results and assumptions can be viewed in the Appendix.
Operational Emissions
Default values used in CalEEMod version 2020.4.0 are based on the California Energy Commission (CEC) sponsored California Commercial End Use Survey (CEUS) and Residential Appliance Saturation Survey (RASS) studies. CalEEMod provides operational emissions of CO2, N2O and CH4. This methodology has been subjected to peer review by numerous public and private stakeholders, and in particular by the CEC; and therefore, is considered reasonable and reliable for use in GHG impact analysis pursuant to CEQA. It is also recommended by CAPCOA (January 2008).
Emissions associated with area sources (i.e., consumer products, landscape maintenance, and architectural coating) were calculated in CalEEMod based on standard emission rates from CARB, USEPA, and district supplied emission factor values (CalEEMod User Guide, 2021). Emissions from waste generation were also calculated in CalEEMod and are based on the IPCC’s methods for quantifying GHG emissions from solid waste using the degradable organic content of waste (CalEEMod User Guide, 2021). Waste disposal rates by land use and overall composition of municipal solid waste in California was primarily based on data provided by the California Department of Resources Recycling and Recovery (CalRecycle).

33 Emissions from water and wastewater usage calculated in CalEEMod were based on the default electricity intensity from the CEC’s 2006 Refining Estimates of Water‐Related Energy Use in California using the average values for Northern and Southern California. Emissions from mobile sources were quantified based on trip generation estimates included in CalEEMod version 2020.4.0 for single‐family residential projects.
Estimate of GHG Emissions
Construction Emissions
Construction activity is assumed to occur over a period of approximately 24 months beginning in early 2023 and concluding in early 2025. Based on CalEEMod results, construction activity for the project would generate an estimated 1,645 metric tons of carbon dioxide equivalent (CO2E), as shown in Table 7. Amortized over a 30‐year period (the assumed life of the project), construction of the proposed project would generate 55 metric tons of CO2E per year.

Operational Indirect and Stationary Direct Emissions
Long‐term emissions relate to energy use, solid waste, water use, and transportation. Each source is discussed below and includes the anticipated emissions that would result from the proposed project.
Energy Use. Operation of onsite development would consume both electricity and natural gas (see Appendix for CalEEMod results). The generation of electricity through combustion of fossil fuels typically yields CO2, and to a smaller extent, N2O and CH4. Natural gas emissions can be calculated using default values from the CEC sponsored CEUS and RASS studies which are built into CalEEMod. As shown in Table 8, the overall net increase in energy use at the project site would result in approximately 532 metric tons of CO2E per year.

34 Water Use Emissions. The CalEEMod results indicate that the project would use approximately 15.3 million gallons of water per year. Based on the amount of electricity generated to supply and convey this amount of water, as shown in Table 9, the project would generate approximately 47 metric tons of CO2E per year. Emissions related to water consumption would be reduced by 20% per Senate Bill X7‐7, by implementing measures that include the installation of low flow plumbing fixtures (i.e., faucets, toilets, show heads) and water efficient irrigation systems.
Solid Waste Emissions. Implementation of a municipal recycling program that would achieve a 75% diversion rate statewide is required for residential uses per the California Integrated Waste Management Act of 1989 (AB 939). The CalEEMod results indicate that the project would result in an approximately 27 metric tons of CO2E per year associated with solid waste disposed within landfills.

Transportation Emissions. Mobile source GHG emissions were estimated using the trip generation rates provided in the Traffic Impact Assessment (TJW Engineering, Inc., March 2022). Trip generation rates for the project were developed utilizing the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition. Table 11 shows the estimated mobile emissions of GHGs for the project based on the estimated annual VMT of 5,768,880. As shown in Table 10, the project would generate approximately 1,864 metric tons of CO2E associated with new vehicle trips.

35 Combined Construction, Stationary and Mobile Source Emissions Table 11 combines the net new construction, operational, and mobile GHG emissions associated with the proposed project. As discussed above, temporary emissions associated with construction activity (approximately 1,645 metric tons CO2E) are amortized over 30 years (the anticipated life of the project).
For the proposed project, the combined annual emissions would total approximately 2,525 metric tons per year in CO2E. The majority (74%) of the project’s GHG emissions are associated with motor vehicular travel. The proposed project is evaluated based on the threshold of 3,000 MT CO2E annually. Project‐related annual GHG emissions would not exceed the threshold of 3,000 metric tons per year; therefore, impacts from GHG emissions would be less than significant per threshold a.

GHG Cumulative Significance. As referenced, specific goals and actions included in Title 24 that pertain to the proposed project include those addressing energy and water use reduction, promotion of green building measures, waste reduction, and reduction in vehicle miles traveled. The proposed project would also be required to implement all mandatory green building measures for new residential development under the CALGreen Code. This would

36 require the project be designed to reduce water consumption, increase building system efficiencies, divert construction waste from landfills, and install low pollutant emitting finish materials. Implementation of these building and appliance standards would result in water, energy, and construction waste reductions for the proposed project. This would result in a less than significant impact under threshold b.
Consistency with EO S‐3‐05 and SB 32
EO S‐3‐05. This EO establishes the following goals: GHG emissions should be reduced to 2000 levels by 2010, to 1990 levels by 2020, and to 80% below 1990 levels by 2050.
SB 32. This bill establishes a statewide GHG emissions reduction target whereby CARB, in adopting rules and regulations to achieve the maximum technologically feasible and cost‐ effective GHG emissions reductions, shall ensure that statewide GHG emissions are reduced to at least 40% below 1990 levels by December 31, 2030. Some of these policies that apply to all projects include implementation of updated building codes for energy efficiency, the low carbon fuel standard, Pavley (California Assembly Bill) vehicle emissions standards and the Renewable Portfolio Standards for utility companies.
As stated, the proposed project would not exceed the 3,000 MT CO2e annual screening threshold defined by SCAQMD; and thus, is not considered a cumulatively considerable source of GHG emissions. However, the project would be required to implement efficiency strategies intended to reduce overall energy and water demand and related GHG emissions associated with generating and conveying energy to the site as well the energy required to treat and convey potable water to the project site. Further, on‐site recycling would be required to achieve the landfill diversion target of 75% as established in SB 1374.
CARB has indicated that statewide, California is on track to achieving both the 2030 and 2050 goals. CARB stated in the First Update to the Climate Change Scoping Plan that “California is on track to meet the near‐term 2020 GHG emissions limit and is well positioned to maintain and continue reductions beyond 2020 as required by AB 32” (CARB 2014, p. ES2).This is confirmed in the 2017 Scoping Plan, which states that the Scoping Plan builds upon the successful framework established by the Initial Scoping Plan and First Update, while identifying new, technologically feasible and cost‐effective strategies to ensure that California meets its GHG reduction targets.
As stated, the project would not generate enough GHG emissions to cumulatively contribute to global climate change; and thus, would not adversely impact the attainment of statewide reductions in GHG emissions referenced above. Standard measures implemented by the project to reduce overall GHG emissions would contribute to GHG reduction goals mandated by AB 32 and further address in EO S‐3‐05 and SB 32.

1.0 INTRODUCTION
On behalf of Richland Communities, VCS Environmental (VCS) prepared this Biological Technical Report, which incorporates the findings from biological surveys conducted by VCS in July/August 2021 and March/April 2022. VCS prepared this report to support California Environmental Quality Act (CEQA) documentation for the San Jacinto Residential Development Project TTM 38202 [herein after referred to as the “Project site”] with the City of San Jacinto (City) as the lead agency.
1.1 Purpose and Approach
This report provides a summary of the conditions present during the July/August 2021 and March/April 2022 biological surveys, which included an assessment of the potential presence of sensitive biological resources, and an analysis of the potential impacts to those resources with implementation of the Project. In 2022, an additional parcel was added to the Project Footprint, therefore additional surveys were conducted in March and April 2022. This report identifies the current biological resources present within the Project Footprint including habitat communities, and the potential for occurrence of special status plant and wildlife species. The potential biological impacts in view of federal, state, and local laws and regulations are also identified in this report. While general biological resources are discussed, the focus of this assessment is on those resources considered to be sensitive. The report also recommends, as appropriate, Best Management Practices (BMPs), avoidance, minimization, and mitigation measures to reduce or avoid potential impacts. This report was prepared based upon results of a literature review and field survey.

2.0 PROJECT DESCRIPTION
The proposed Project would develop an approximately 33.8-acre vacant site with up to 181 singlefamily residential homes and associated infrastructure. The Project requires subdividing five (5) existing parcels (APNs 436-280-011, 436-280-012, 436-280-013, 436-280-014 and 436-280-025).
Offsite improvements include connecting the proposed internal circulation system to the intersections of Lyon Avenue/Appaloosa Drive and Marilyn Drive/Estrella Street; connecting to existing utility systems within Lyon Avenue; frontage improvements along Lyon Avenue including a Class I multi-use path (per City of San Jacinto Trails Master Plan), sidewalk and street lights; and constructing a portion of the San Jacinto Valley Master Drainage Plan storm drain system Line G3 from Marilyn Drive/Estrella Street along the northeast edge of the development to a future connection point (note: continuation of Line G-3 to be constructed by others) at the Monte Vista Middle School property to the north.
2.1 Current Conditions and Past Site Use
The Project site is surrounded by residential development, with rural residential homes to the south. It has previously been used as a horse ranch and heavily disturbed. The Project Footprint supports three (3) vegetation community/land cover types which includes herbaceous non-native forbs and grasses, ornamental palms, and developed areas. A majority of the site is maintained as part of weed abatement. A section of the Project site to the south is rural residential with scattered piles of trash and debris. Site photographs are attached as Appendix A.
The topography throughout the Project Footprint is generally flat. Elevations on the Project Footprint range from 1,505– 1,510 feet (~458 – 460 meters) above mean sea level (MSL) (Google Earth 2021).

3.1 Impacts Terminology
Potential impacts to biological resources that could result from implementation of the proposed Project are discussed in each of the Vegetation, Wildlife, and Jurisdictional Waters sections presented in this report.
Biological resources may be either directly or indirectly impacted by a project. Furthermore, direct and indirect impacts may be either permanent or temporary in nature. These impact categories are defined below. These terms will be used throughout the document. • Direct Impact: Any loss, alteration, disturbance, or destruction of biological resources that would result from project-related activities is a direct impact. Examples include vegetation clearing, encroaching into wetlands, diverting natural surface water flows, and the loss of individual species and/or their habitats. Direct impacts are long-term. • Indirect Impact: As a result of project-related activities, biological resources may also be affected in a manner that is not direct. Examples of indirect impacts include elevated noise, light, and dust levels, increased human activity, decreased water quality, erosion created by the removal of vegetation, and the introduction of invasive plants and unnatural predators (e.g., domestic cats and dogs). These indirect impacts may be both short-term and long-term in their extent.
• Permanent Impacts: All impacts that result in the long-term or irreversible removal of biological resources are considered permanent. Examples include constructing a building or permanent road on an area containing biological resources. • Temporary Impacts: Any impacts considered to have reversible effects on biological resources can be viewed as temporary. Examples include the generation of fugitive dust during construction, removing vegetation, and either allowing the natural vegetation to recolonize or actively revegetating the Project Footprint.
Under each section, potential impacts are discussed.

4.0 METHODS
4.1 Literature Review
4.1.1 Sensitive Plant Communities
Sensitive plant communities (sensitive habitats) as defined below, are of limited distribution statewide or within a county or region and are often vulnerable to environmental effects of projects. Sensitive habitats are often threatened with local extirpation and are therefore considered as valuable biological resources. Plant communities are considered “sensitive” by the California Native Plant Society (CNPS) and CDFW if they meet any of the following criteria listed below.
• The habitat is recognized and considered sensitive by CDFW, United States Fish and Wildlife Service (USFWS), and/or special interest groups such as CNPS. • The habitat is under the jurisdiction of the USACE pursuant to Section 404 of the CWA. • The habitat is under the jurisdiction of the CDFW pursuant to Sections 1600 through 1612 of the FGC.
• The habitat is known or believed to be of high priority for inventory in the California Natural Diversity Database (CNDDB).
• The habitat is considered regionally rare.
• The habitat has undergone a large-scale reduction due to increased encroachment and development.
• The habitat supports special status plant and/or wildlife species (defined below). • The habitat functions as an important corridor for wildlife movement.
The most current version of CDFW’s List of California Sensitive Natural Communities indicates which natural communities are sensitive given the current state of the California classification (CDFW 2021b).
4.1.2 Special Status Species
Species of plants and wildlife are afforded “special status” by federal agencies, state agencies, and/or non-governmental organizations (e.g., USFWS, CDFW, CNPS, and United States Forest Service [USFS]) because of their recognized rarity, potential vulnerability to extinction, and local importance. These species typically have a limited geographic range and/or limited habitat and

are referred to collectively as “special status” species. Plant and wildlife species are considered “special status” species if they meet any of the following criteria:
• Taxa with official status under ESA, CESA, and/or the Native Plant Protection Act (NPPA). • Taxa proposed for listing under ESA and/or CESA.
• Taxa designated a species of special concern or a state fully protected species by CDFW. • Taxa identified as sensitive, unique or rare, by the USFWS, CDFW, USFS, and/or the Bureau of Land Management (BLM).
• Plants that meet the definition of rare or endangered under the California Environmental Quality Act (CEQA) §15380(b) and (d). Species that may meet the definition of rare or endangered include the following:
− Species considered by CNPS and CDFW to be “rare, threatened or endangered in California” (California Rare Plant Rank [CRPR] 1A, 1B and 2; CNPS 2021). A majority of the CRPR 3 and CRPR 4 plant species generally do not qualify for protection under CESA and NPPA.
− Species that may warrant consideration on the basis of local significance or recent biological information.
− Some species included on the CNDDB Special Vascular Plants, Bryophytes, and Lichens List (CDFW 2021c).
• Considered a locally significant species, that is, a species that is not rare from a statewide perspective but is rare or uncommon in a local context such as within a county or region (CEQA §15125 (c)) or is so designated in local or regional plans, policies, or ordinances.
Examples include a species at the outer limits of its known range or a species occurring on an uncommon soil type.
Available literature and databases were reviewed regarding sensitive habitats and special status species. Special status species that have the potential to occur within the immediate region of the Project Footprint were identified. Several agencies, including the USFWS, CDFW, and CNPS publish lists of particular taxa (species and subspecies) and the associated level of protection or concern associated with each. Reviewed and consulted literature and databases focused on the Project Footprint and included the following sources listed below:
• The CNDDB, a CDFW species account database that inventories status and locations of rare plants and wildlife in California, was used to identify any sensitive plant communities and

special status species that may exist within a two-mile radius of the Project Footprint (CDFW 2022a) (Figure 4).
• Online CNPS Inventory of Rare and Endangered Plants of California (CNPS 2022). A search for the USGS 7.5-Minute San Jacinto and Lakeview Quadrangles provided information regarding the distribution and habitats of special status vascular plants in the vicinity of the Project.
• A map of USFWS critical habitat to determine species with critical habitat mapped in the general vicinity of the Project (USFWS 2021a).
• Pertinent maps, scientific literature, websites, and regional flora and fauna field guides.
The literature review provided a baseline from which to inventory the biological resources potentially occurring within the Project Footprint, as well as the surrounding area. Although the inventory list of special status wildlife species was not exhaustive of all species that might be of concern for the property, it provided a wide range of species that are representative of the wildland habitats in the area. Species occurrence and distribution information is often based on documented occurrences where opportunistic surveys have taken place; therefore, a lack of records does not necessarily indicate that a given species is absent from the Project Footprint.
4.1.3 Jurisdictional Waters
The following sources were reviewed to determine the potential presence or absence of jurisdictional streams/drainages, wetlands, lakes, and their location within the watersheds associated with the Project Footprint, and other features that might contribute to federal or state jurisdictional authority located within watersheds associated with the Project Footprint:
• National Wetlands Inventory (NWI) maps (USFWS 2022b). The NWI database indicates potential wetland areas based on changes in vegetation patterns as observed from satellite imagery. This database is used as a preliminary indicator of wetland habitats because the satellite data is not precise;
• USGS National Hydrography Dataset (NHD). Provides the locations of “blue-line” streams as mapped on 7.5-Minute Topographic Map coverage; • Aerial Imagery;
• USGS 7.5-Minute Topographic Maps; and
• Natural Resource Conservation Service (NRCS) Soil Survey.

4.2 Field Methodology
4.2.1 Vegetation Communities and Plants
A general biological survey was conducted within the Project Footprint on July 8, 2021 and on March 18, 2022, by VCS biologists Molly Burdick-Whipp, Carla Marriner, and Sierra Valladares. The vegetation communities and habitat conditions were inspected to confirm presence and habitat quality of the vegetation found onsite. Where appropriate, descriptions of vegetation communities from the Manual of California Vegetation (MCV) second edition (Sawyer et al. 2009) were also utilized. Any deviations from standard vegetation classifications were made on best professional judgment when areas did not fit into a specific habitat description provided by the MCV. Vegetation communities were mapped using field observations and utilizing aerial imagery.
A rare plant/Narrow Endemic Plant habitat assessment was conducted within the Project Footprint on August 19, 2021, by botanist CJ Fotheringham. During the habitat assessment, the botanist walked the entirety of the Project Footprint, paying special attention to those areas that could host sensitive vegetation communities or had the potential to provide suitable habitat for special status plant species. Due to the time of year and conditions of the site, a complete rare plant survey could not be done to meet the standards of the Narrow Endemic Plants overlay of the MSHCP and provide a definitive conclusion on rare plants. Therefore, a focused rare plant survey was conducted on April 20, 2022 during the blooming period for most sensitive species. Plant species were identified using plant field and taxonomical guides, such as The Jepson Manual:
Vascular Plants of California, second edition (Baldwin et al. 2012). All plant species encountered during the field survey were identified and recorded in field notes.
4.2.2 Wildlife
During the July 8, 2021 and March 18, 2022 survey, biologists analyzed the Project Footprint for habitat areas that could be suitable for special status wildlife species. All wildlife species encountered visually or audibly during the field surveyswere identified and recorded in field notes.
Signs of wildlife species including wildlife tracks, burrows, nests, scat and remains, were also recorded. Binoculars were used to aid in the identification of observed wildlife and in areas not accessible on foot. Wildlife field guides and photographs were used to assist with identification of wildlife species during the field survey, as necessary. Assessments of presence/absence and potential for occurrence were made based on presence of suitable habitat to support the species, diagnostic signs (burrows, scat, tracks, vocalizations, and nests), known records or occurrence within the area, known distribution and elevation range, and habitat utilization from the relevant literature.
Projects within the MSHCP Burrowing Owl Survey Area are subject to the MSHCP burrowing owl (Athene cunicularia) survey requirements. A portion of the Project is within the MSHCP Burrowing

Owl Survey Area; therefore, a burrowing owl habitat assessment was performed for the entire site. The burrowing owl assessment followed the guidelines identified in Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan Area (County of Riverside 2006). The survey instructions note the following steps to the MSHCP burrowing owl assessment:
• Step 1: Habitat Assessment
• Step 2: Locating Burrows and Burrowing Owls
o Part A: Focused Burrow Survey
o Part B: Focused Burrowing Owl Surveys (4 separate surveys) Habitat assessments were performed by VCS biologists on July 8, 2021 and March 18, 2022 for the additional parcel that was added to the Project Footprint in early 2022. The methodology for these surveys is further detailed in the MSHCP Burrowing Owl Survey Report dated August 26, 2021, updated on May 5, 2022 attached as Appendix D.
4.2.3 Jurisdictional Waters
During the August 6, 2021 and March 18, 2022 biological surveys, VCS biologists assessed the presence or absence of potential jurisdictional streams/drainages and conducted a wetland delineation on the Project Footprint. During the field surveys, the Project Footprint was assessed for jurisdictional wetland and non-wetland Waters of the United States (WOUS). To determine the presence of a wetland, three indicators are required: (1) hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology. The RWQCB has exceptions to this methodology in situations where a site has soils and hydrology, but no vegetation is present; these areas may be considered wetlands by the RWQCB. The methodology published in the United States Army Corps of Engineers 1987 Wetland Delineation Manual and the Arid West Supplement sets the standards for meeting each of the three indicators, which normally require that 50 percent or more dominant plant species typical of a wetland, soils exhibiting characteristics of saturation, and hydrological indicators be present. Jurisdictional non-wetland Waters of the United States are typically determined through the observation of an Ordinary High Water Mark (OHWM), which is defined as the “line on the shore established by the fluctuation of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.” Projects with impacts to Waters of the United States are regulated under Sections 401 and 404 of the Clean Water Act.
On June 22, 2020, a revised Navigable Waters Protection Rule regarding jurisdictional Waters of the United States went into effect. The revised rule stated that Waters of the United States do not include ephemeral features that flow only in direct response to precipitation, including ephemeral streams, swales, gullies, rills, and pools. Consistent with the U.S. District Court for the District of

Arizona’s August 30, 2021, order vacating and remanding the Navigable Waters Protection Rule, the regulatory agencies have halted implementation of the Navigable Waters Protection Rule and are interpreting Waters of the United States consistent with the pre-2015 regulatory regime until further notice.
The following guidance documents were utilized in making this determination:
• Field Guide to OHWM Determinations in the Arid West (August 2008); • Updated OHWM Datasheet for the Field Guide to OHWM Determinations in the Arid West (July 2010); and
• Ordinary High Flows and the Stage‐Discharge Relationship in the Arid West Region (2011).
The CDFW and the RWQCB take jurisdiction over Waters of the State (WOS) and Riparian/Riverine resources (California Fish and Game Code §§1600 et seq.; California Code of Regulations, Title 14, §720). Section 1602 of the California Fish and Game Code (FGC) applies to natural rivers, streams, and lakes:
“An entity may not substantially divert or obstruct the natural flow of, or substantially change or use any material from the bed, channel, or bank of, any river, stream, or lake, or deposit or dispose of debris, waste, or other material containing crumbled, flaked, or ground pavement where it may pass into any river, stream, or lake.” The Project Footprint was assessed for jurisdictional WOS during the field survey using guidance from Section 1600 of the FGC and Brady and Vyverberg (2013), which defines a stream as “a body of water that flows perennially or episodically and that is defined by the area in which water currently flows, or has flowed, over a given course during the historic hydrologic course regime, and where the width of its course can reasonably be identified by physical or biological indicators.” CDFW regulates wetland areas only to the extent that those wetlands are part of a stream, river, or lake as defined by the CDFW.

5.0 RESULTS
5.1 Vegetation
5.1.1 Vegetation Communities/Land Cover
Vegetation/land cover mapping and acreages for each vegetation community and land type within the Project Footprint can be found in Table 1 and are depicted on Figure 5. A vegetation community/land cover is 0.10 acre or larger in size. The majority of the vegetation within the Project Footprint is characterized by maintained open fields comprised of herbaceous non-native forbs and grasses vegetated with a variety of non-native and early successional weedy plant species. Vegetation management activities (mowing) had occurred within the entire Project Footprint prior to the July/August 2021 site visit; however no mowing had occurred prior to the March/April 2022 surveys allowing more vegetation to grow.
The Project Footprint mostly consists of non-native plant species. Common non-native plant species observed during the surveys included foxtail barley (Hordeum murinum), coastal heron’s bill (Erodium cicutarium), short-pod mustard (Hirschfeldia incana), and Russian thistle (Salsola tragus). Common native species observed included fiddleneck (Amsinckia menziesii), and salt heliotrope (Heliotropium curassavicum). Note, one Fremont cottonwood (Populus fremontii), approximately 25 feet in height and one goldenrain tree (Koelreuteria paniculata) was observed onsite, however these were single trees and therefore not vegetation communities large enough to call out separately.
Representative photographs of the Project Footprint are included as Appendix A.

during the summer season, however vegetation had grown back by the March 2022 survey. Native plant species observed within this area include fiddleneck, Jimsonweed (Datura wrightii), salt heliotrope, salt grass (Distichlis spicata), and one Fremont cottonwood tree. Non-native plant species observed include barley, short-pod mustard, and stinknet (Oncosiphon piluliferum). A full list of plant species observed is included as Appendix B.
5.1.1.2 Ornamental Palms
Approximately 0.15 acre of ornamental palms was mapped within the northwestern corner of the Project Footprint. This community includes 13 Mexican fan palms (Washingtonia robusta) planted in a row along the northern boundary.
5.1.1.3 Disturbed/Developed
Approximately 2.76 acre of disturbed/developed area was mapped along the western boundary and a section in the middle of the site near the southern boundary of the Project Footprint. The western area of the Project Footprint is a paved portion of Lyon Avenue that will be directly impacted for street, stormwater, and utility infrastructure. The area in the middle near the southern boundary is considered disturbed as there is very little cover of non-native grasses and contains mostly bare areas, trash/debris, and old RV trailers.
5.1.1.4 Special Status Vegetation Communities
The Project Footprint does not support any sensitive vegetation communities. Southern Cottonwood Willow Riparian Forest habitat was reported in the CNDDB approximately 1 mile north-northwest of the Project site but is not present within the Project Footprint.
5.1.2 Plants
A total of 37 plant species were observed within the Project Footprint during the August 2021 and the April 2022 plant surveys and are listed in Appendix B.
5.1.2.1 Sensitive Plant Species with Potential to Occur Sensitive plant species include federally, or state listed threatened or endangered species and those species listed on CNPS’s rare and endangered plant inventory. Species with the potential to occur onsite were analyzed based on distribution, habitat requirements, and existing site conditions, and are listed in Appendix C.
No sensitive plant species were observed within the Project Footprint during the August 19, 2021 botanical habitat assessment, the April 20, 2022 focused rare plant survey, or the July/August 2021 and March/April 2022 biological surveys. Based on the lack of suitable habitat onsite and the

negative findings during the April 20, 2022 focused rare plant survey, sensitive plant species are not expected to occur within the Project Footprint.
5.1.3 Soils
The U.S. Department of Agriculture Natural Resources Conservation service (NRCS 2021) identifies seven (7) soil types present within the Project Footprint (Figure 6; Soil Map).
Soil types in the Project Footprint generally consist of Grangeville loamy fine sand and sandy loam, Dello loamy sand and loamy fine sand, Traver loamy fine sand, and Chino silt loam. See below for a complete list of soil types identified within the site. • Grangeville Series: This series consists of very deep, somewhat poorly drained soils that formed in moderate coarse textured alluvium dominantly from granitic rock sources.
Grangeville soils are on alluvial fans and floodplains. Some areas are saline and saline-sodic affected.
• GoB - Grangeville loamy fine sand, drained, 0 to 5 percent slopes • GtA – Grangeville fine sandy loam, drained, 0 to 2 percent slopes • GwA – Grangeville fine sandy loam, loamy substratum, drained, 0 to 2 percent slopes
• Dello: This series consist of very deep, somewhat poorly drained soils that formed in alluvium from granitic rock sources. In some areas a water table is more than 6 feet from the surface because of flood control structures and/or installed drains. The frequency of flooding is rare or occasional.
• DrA – Dello loamy fine sand, gravelly substratum, 0 to 2 percent slopes • DgB – Dello loamy sand, 0 to 5 percent slopes
• Traver Series: The Traver series is a member of a coarse-loamy, mixed, thermic family of Natric Haploxeralfs. The alluvium is from granitic bedrock. The soils are variable in content of salts and alkali but usually contain moderate to strong amounts. Moderately well to somewhat poorly drained, with moderate to slow permeability and slow runoff. • Tr2 - Traver loamy fine sand, saline-alkali, eroded
• Chino Series: This series consists of deep, somewhat poorly drained soils that are formed from alluvium derived from granite. Chino soils are found on flood plains. • Cf – Chino silt loam, drained, saline alkali

A complete list of sensitive wildlife species analyzed with potential to occur within the Project Footprint are included in Appendix C. The six sensitive species noted above with high or moderate potential to occur are described in further detail below.
Burrowing Owl
The burrowing owl is a small, tan, ground‐dwelling owl that occupies and nests in underground burrows. The species is associated with grasslands and other arid open terrain throughout much of the western United States. Burrowing owls are opportunistic in their selection of burrows, typically utilizing the burrows of small mammals, drainpipes, culverts, and other suitable cavities

at or below ground level. In California, the species often occurs in association with colonies of the California ground squirrel (Otospermophilus beecheyi), where it makes use of the squirrel’s burrows. A burrow can be up to 10 feet in length with an enlarged terminal nesting chamber. The entrance of the burrow is often adorned with animal dung, feathers, debris, and other small objects. The species is active both at day and at night and may be seen perching conspicuously on fence posts or standing at the entrance of their burrows.
Due to the characteristic fossorial habits of burrowing owls, burrows are a critical component of their habitat. In southern California, burrowing owls are not only found in undisturbed natural areas, but also fallow agricultural fields, margins of active agricultural areas, berms to flood control and creek channels, livestock farms, airports, and vacant lots. Declines in burrowing owl populations are attributed to loss and degradation of habitat, to ongoing residential and commercial development, and to rodent control programs.
No burrowing owls or signs of burrowing owl were observed during the July/August 2021 or March/April 2022 focused surveys. There have been no previous burrowing owl observations recorded onsite. The site provides suitable habitat for the species, including suitably sized burrows (>4 inches in diameter) and grassland habitat for foraging, although the site generally lacks suitable perches for owls. Overall, suitable habitat for burrowing owl is present onsite and multiple recorded observations of the species occur within 2 miles of the Project Footprint.
Ferruginous Hawk
Ferruginous hawks are open-country birds that breed in grasslands, sagebrush country, saltbushgreasewood shrublands, and edges of pinyon-juniper forests at low to moderate elevations. Their breeding habitat includes features such as cliffs, outcrops, and tree groves for nesting. West of the Rockies, Ferruginous Hawks spend the winter in grasslands or deserts with abundant rabbits, pocket gophers, or prairie dogs. This species is present in southern California in the winter. This species was not observed during the July/ August 2021 or March/April 2022 surveys. This species has a moderate potential to occur within the Project Footprint for foraging in the winter, however the site lacks suitable nesting habitat for the species.
Grasshopper Sparrow
The grasshopper sparrow is a stubby-tailed and bull-necked songbird found in grasslands, prairies, hayfields, and open pastures with little to no scrub cover and often with some bare ground. When not singing its quiet, insect like song from atop a stalk in a weedy pasture, it disappears into the grasses where it usually runs along the ground rather than flies. This species was not observed during the July/ August 2021 or March/April 2022 surveys. The grasshopper sparrow has a moderate potential to occur within the Project Footprint for foraging, however the site lacks suitable nesting habitat for the species.

Loggerhead Shrike
The Loggerhead Shrike is a songbird with a raptor’s habits. A denizen of grasslands and other open habitats throughout much of North America, this masked black, white, and gray predator hunts from utility poles, fence posts and other conspicuous perches, preying on insects, birds, lizards, and small mammals. This species was not observed during the July/August 2021 or March/April 2022 surveys. There is moderate potential for this species to occur onsite as suitable foraging habitat and prey are available, however, the site lacks suitable nesting habitat for this species.
Western Yellow Bat
The western yellow bat is a year-round resident of southern California, found below 2000 feet in or near foothill or desert riparian habitats. The species roosts in trees, including palm trees, in and near palm oases and riparian habitats. Bat roosts were not incidentally observed during the July/August 2021 or March/April 2022 surveys. The Project Footprint contains a few palm trees that could be potential roosting and foraging habitat.
Western Red Bat
The western red bat is locally common in some areas of California, occurring from Shasta County to the Mexican border, west of the Sierra Nevada/Cascade crest. The species roosts primarily in trees, sometimes shrubs usually in edge habitats adjacent to streams, fields, or urban areas. Bat roosts were not incidentally observed during the July/August 2021 or March/April 2022 surveys.
5.2.2 Critical Habitat
The USFWS’s online service for information regarding Threatened and Endangered Species Final Critical Habitat designation within California was reviewed to determine if the Project Footprint occurs within any species designated Critical Habitat. Critical Habitat for San Bernardino Merriam’s kangaroo rat (Dipodomys merriami parvus) occurs approximately 2.0 miles northeast of the Project site (Figure 7).
5.2.3 Wildlife Movement
Wildlife corridors link together areas of suitable habitat that are otherwise separated by rugged terrain, changes in vegetation, or human disturbance. The fragmentation of open space areas by urbanization creates isolated “islands” of wildlife habitat. Corridors effectively act as links between different populations of a species. An increase in a population’s genetic variability is generally associated with an increase in a population’s health.

Biological Technical Report
18 May 2022
Corridors mitigate the effects of habitat fragmentation by:
• Allowing wildlife to move between remaining habitats, which allows depleted populations to be replenished and promotes genetic diversity;
• Providing escape routes from fire, predators, and human disturbances, thus reducing the risk that catastrophic events (such as fires or disease) will result in population or local species extinction; and
• Serving as travel routes for individual wildlife species as they move within their home ranges in search of food, water, mates, and other needs (Fahrig and Merriam 1985, Simberloff and Cox 1987, Harris and Gallagher 1989).
Wildlife movement activities usually fall into one of three movement categories:
• Dispersal (e.g., juvenile animals from natal areas, individuals extending range distributions);
• Seasonal migration; and
• Movements related to home range activities (foraging for food or water, defending territories, searching for mates, breeding areas, or cover).
The Project Footprint is located adjacent to both residential development and open space parcels, while the site itself is comprised of fields dominated by non-native grasses and forbs. Because the site has open fields, the Project Footprint plays a minor role in local wildlife dispersal and foraging.
Common wildlife species including coyotes, skunks, opossums, and raccoons may travel through the site and neighboring developed or open areas, but the site does not provide connectivity between large areas of open space on a local or regional scale. The site is not within a significant regional wildlife movement corridor and is not considered to play a significant role in regional wildlife movement.
5.2.4 Avian Nesting and Bat Roosts
There is potential for avian nesting within the Project Footprint. The open fields provide suitable habitat for ground-nesting avian species. The few trees onsite provide suitable habitat for tree nesting avian species. The palm trees and cottonwood tree are potential suitable bat roosting habitat within the Project Footprint. The biologists did not observe signs of nests, nesting activity or bat roosting within the Project Footprint during the July/August 2021 and March/April 2022 biological surveys.

5.3 Jurisdictional Waters
5.3.1 National Wetland Inventory
No aquatic features are mapped within the Project Footprint boundary on the USFWS’s National Wetland Inventory (USFWS [2021b]) as shown in Figure 8.
5.3.2 Hydrology
The Project lies within the San Jacinto watershed. The closest significant aquatic features to the site include the San Jacinto River, located approximately 2.2 miles to the northeast, and the San Jacinto Reservoir, located approximately 0.5-mile northwest of the Project Footprint. The San Jacinto Reservoir is operated by the Eastern Municipal Water District, which also operates the San Jacinto Valley Regional Water Reclamation Facility located west of the site.
5.3.3 Jurisdictional Waters
There are no streambed or drainage features containing waters of the United States or waters of the State on the Project Footprint. A non-jurisdictional interim channel is located along the northern boundary in the northeastern section of the Project Footprint. The interim channel will ultimately be undergrounded as the storm drain system for this region is built out. This channel is an excavated upland channel with no natural flow of water and lacks riparian or wetland vegetation. There is no historic drainage course that connects to this channel, and the only source of water flow is through pumping from an upstream concrete lined facility that stores urban runoff. Additionally, the adjacent Monte Vista Middle School project concluded this channel to be non-jurisdictional prior to construction.

6.0 PROJECT IMPACTS
6.1 Vegetation
6.1.1 Potential Impacts to Vegetation Communities
Potential impacts to vegetation communities/land cover types due to implementation of the Project includes the entire Project Footprint, totaling approximately 35.06 acres, which includes type habitats as shown below in Table 2.
Table 2. Potential Impacts to Vegetation Communities within the Project Footprint Vegetation Community/Land Cover Type
Project
Footprint
(acres)
Herbaceous Non-Native Forbs and Grasses 32.15
Ornamental Palms 0.15
Disturbed/Developed 2.76
Total 35.06
Direct impacts to Herbaceous Non-native Forms and Grasses, Ornamental Palms, and Developed area are considered less than significant because these habitats/land covers are comprised mostly of non-native vegetation or no vegetation, are common in the surrounding vicinity, and do not represent CNDDB or CDFW sensitive plant communities.
6.1.2 Potential Impacts to Special Status Plants
The Project Footprint does not support any sensitive vegetation communities. Based on lack of suitable habitat onsite and negative findings during the April 2022 focused rare plant survey, special status plant species are not anticipated to occur within the Project Footprint. No impacts to special status plants are anticipated as a result of Project implementation.
6.2 Wildlife
6.2.1 Potential Impacts to Special Status Wildlife
While not observed during the biological surveys, ferruginous hawk, grasshopper sparrow, loggerhead shrike, western yellow bat, and western red bat have a moderate potential to occur on the Project Footprint for foraging, however, the site exhibits limited nesting or roosting habitat for these species. The loss of approximately 34 acres of foraging habitat for these species would not decrease populations below self-sustaining levels given the availability of habitat remaining in the region. Therefore, impacts would be less than significant per CEQA. Individuals are expected

to move to adjacent habitat during construction activities; therefore, there would be no direct mortality on these species. To avoid impacts to avian and bat species during the nesting/maternity season, construction activities on the Project Footprint would be implemented in accordance with mitigation requirements outlined in Section 10.0 below.
Burrowing owl are known to use both fallow and active agricultural fields for foraging and nesting.
The species has moderate potential to occur as suitable burrows are present and multiple occurrences of this species have been documented within two miles of the site. No burrowing owl or sign of burrowing owl was observed during the focused surveys. Construction activities at the Project Footprint would be implemented in accordance with mitigation requirements outlined in Section 10.0 below.
The remaining species listed in Appendix C are not expected to occur on the Project Footprint due to the lack of suitable habitat or the Project Footprint is outside the known elevation range for the species. Therefore, there would be no impact on these species and no mitigation would be required.
With the inclusion of standard BMPs as noted in Section 9.0, Best Management Practices, and mitigation recommendations in Section 10.0, Mitigation Recommendations, potential impacts to these special status wildlife species would be considered less than significant.
6.2.2 Potential Impacts to Critical Habitat
The Project Footprint does not fall within any USFWS-designated Critical Habitat.
6.2.3 Potential Impacts to Wildlife Movement/Nesting/Bat Roosts Wildlife Movement
As described earlier, the Project Footprint may serve a function in local wildlife dispersal and foraging; however, due to the disturbed nature of the site and the degraded habitats, the loss of foraging habitat and/or effect on local wildlife movement would be less than significant. No longterm or significant effects to wildlife movement are anticipated due to Project implementation.
Nesting Birds/Raptor Foraging Habitat
Due to the potential for onsite bird nesting and foraging habitat for raptors, Project construction could result in impacts to nesting birds. Recommended measures include a pre-construction nesting bird survey and biological monitoring as needed to avoid impacts and are outlined in Section 9.0 Best Management Practices and 10.0, Mitigation Recommendations, of this report.
These measures would ensure potential impacts to nesting birds are less than significant.

Bat Foraging and Roosting Habitat
The potential for bat roosting is moderate within the Project Footprint and the existing vegetation onsite represents marginally suitable foraging habitat. Permanent impacts on foraging and roosting habitat would be less than significant given the habitat onsite is marginal and given the availability of other locations with suitable roosting and foraging habitat remaining in the Project Vicinity and region. Therefore, no mitigation would be required for permanent impacts within the Project Footprint. To ensure no impacts to roosting bats occur during temporary construction activities, mitigation measures BIO-1(a-b) detailed in Section 10.0, Mitigation Recommendations, will be implemented.
6.3 Jurisdictional Waters
6.3.1 Potential Impacts to Jurisdictional Waters
No streambed or drainage features containing waters of the United States or waters of the State are present on the Project Footprint.

7.0 MSHCP CONSISTENCY ANALYSIS
The purpose of this section is to provide an analysis of the proposed Project with respect to compliance with biological aspects of the Western Riverside County MSHCP. The following information is provided relating the Project Footprint to geographic areas of the MHSCP that are relevant to reserve assembly and planning. This information will form the basis of a consistency determination for the Project.
Section 6 of the MSHCP states that all Projects must be reviewed for compliance with plan policies pertaining to Riparian/Riverine resources, Criteria resources, Narrow Endemic Plant Species, urban/wildlands interface, and additional survey needs as applicable.
Land cover types present within the Project Footprint and permanent impacts to land cover types were previously described in Sections 5.1 and 6.1, respectively, of this Biological Technical Report.
7.1 Reserve Assembly Analysis
The Project is located within the San Jacinto Valley Area Plan of the MSHCP within the San Jacinto Habitat Management Unit. The Project Footprint is not located within an MSHCP Criteria Cell or Cell Group. As such, the Project is not subject to the Joint Project Review (JPR) or Habitat Acquisition and Negotiation (HANS) processes.
7.2 Project Area in Relation to MSHCP
7.2.1 Public Quasi-Public Lands
The Project is not located on Public Quasi-Public (PQP) lands. The nearest PQP lands are located within portions of the San Jacinto River, approximately 2.2 miles northeast of the Project Footprint.
The Project will not directly or indirectly impact PQP lands.
7.2.2 Covered Roads
Lyon Avenue, which occurs directly west of the Project Footprint, is identified as a Covered Road on the Western Riverside County Regional Conservation Authority’s MSHCP Information Map (MSHCP, 2021). Approximately 1.26 acres of Lyon Avenue will be subject to impacts as part of roadway improvement activities, the total which does not exceed the covered road acreage for this road.
7.2.3 Urban/Wildlands Interface (Section 6.1.4)
The MSHCP recognizes that future development in proximity to existing or proposed MSHCP Conservation Areas might result in indirect edge effect conditions that will adversely affect biological resources within the MSHCP Conservation Area. The MSHCP provides guidelines to

address the indirect effects of urban/wildlands interfaces, as outlined in Section 6.1.4, including conditions relating to drainage, toxics, lighting, noise, invasive plant species, barriers, and grading/land development.
The proposed Project is not located within or in proximity to a Conservation Area, which include PQP lands. Thus, guidelines to address the indirect effects of urban/wildlands interfaces as presented in Section 6.1.4 are not required of the Project.
7.3 Protection of Species Associated with Riparian/Riverine Areas and Vernal Pools (Section 6.1.2)
The proposed Project Footprint was assessed for MSHCP Section 6.1.2 resources, including riparian/riverine resources, vernal pools, fairy shrimp, and riparian birds.
7.3.1 Riparian/Riverine
7.3.1.1 Methods
Section 6.1.2 of the MSHCP states that “riparian/riverine resources are lands which contain habitat dominated by trees, shrubs, persistent emergent [wetland plant species], or emergent mosses and lichens, which occur close to, or which depend upon moisture from a nearby freshwater source; or areas with freshwater after flow during all or a portion of the year.” To determine the areas where “Riparian/Riverine Areas” are present, the delineators conducted site visits to walk the entire Project Footprint and reviewed historical aerial imagery.
VCS performed a jurisdictional delineation and vegetation mapping onsite in August 2021. All areas of the Project Footprint were evaluated for the presence of riparian/riverine areas, including wetlands. All drainages encountered were also examined for connectivity or lack of connectivity to other hydrologic features. Dominant vegetation within the drainages or adjacent to the drainages were identified and recorded.
7.3.1.2 Existing Conditions and Results
The Project Footprint does not contain any MSHCP riverine/riparian resources. A non-jurisdictional interim channel is located along the northern boundary in the northeastern section of the Project Footprint. The interim channel will ultimately be undergrounded as the storm drain system for this region is built out. This channel is an excavated upland channel with no natural flow of water and lacks riparian or wetland vegetation. There is no historic drainage course that connects to this channel, and the only source of water flow is through pumping from an upstream concrete lined facility that stores urban runoff. Additionally, the adjacent Monte Vista Middle School project concluded this channel to be non-jurisdictional prior to construction.

7.3.1.3 Impacts
The Project does not contain MSHCP riverine/riparian resources, therefore no impacts will occur.
7.3.1.4 Mitigation
The Project does not contain MSHCP riverine/riparian resources, therefore no mitigation is proposed.
7.3.2 Vernal Pools and Fairy Shrimp
7.3.2.1 Methods
Section 6.1.2 of the MSHCP states that “Vernal pools are seasonal wetlands that occur in depression areas that have wetland indicators of all three parameters (soils, vegetation and hydrology) during the wetter portion of the growing season but normally lack wetland indicators of hydrology and/or vegetation during the drier portion of the growing season”.
The entire Project Footprint was assessed for potential vernal pool habitat during the August 2021 and March 2022 biological surveys. In addition, the following sources were reviewed to aid in the site assessment for vernal pool habitat: National Wetlands Inventory (NWI), current and historic aerial imagery, and NRCS Soil Survey.
7.3.2.2 Existing Conditions and Results
During the site visit, no evidence of ponding water, such as visible surface water, cracked soils, or hydric soils were observed. Additionally, no vegetation typical of vernal pools or seasonal depressions was observed. Based on the lack of typical features that could collect water, lack of ponding water evidence, and the lack of vegetation typical of vernal pools or seasonal depressions, suitable conditions for vernal pools, fairy shrimp, and other sensitive species associated with vernal pools are not considered present on site.
7.3.3 Riparian Birds
The MSHCP lists five bird species for protection based off association with riparian/riverine and vernal pool habitats. These species include bald eagle (Haliaeetus leucocephalus), least Bell’s vireo (Vireo bellii pusillus), peregrine falcon (Falco peregrinus), southwestern willow flycatcher (Empidonax traillii extimus), and western yellow-billed cuckoo (Coccyzus americanus occidentalis).
No riparian riverine or vernal pool resources occur onsite; therefore, an assessment of riparian bird habitat is not required, and no impacts to these species are anticipated to occur.
7.4 Protection of Narrow Endemic Plant Species (Section 6.1.3) A portion of the Project Footprint occurs within a Narrow Endemic Plant Survey Area for the following species:

• California Orcutt grass (Orcuttia californica)
• Wright’s trichocoronis (Trichoconis wrightii var. wrightii)
7.4.1 Methods
A rare plant habitat assessment was conducted within the Project Footprint on August 25, 2021 and a focused rare plant survey was conducted on April 20, 2022, by botanist CJ Fotheringham.
During the habitat assessment and survey, the botanist walked the entirety of the Project Footprint, paying special attention to those areas that could host sensitive vegetation communities or had the potential to provide suitable habitat for special status plant species. Plant species were identified using plant field and taxonomical guides, such as The Jepson Manual:
Vascular Plants of California, second edition (Baldwin et al. 2012). All plant species encountered during the field survey were identified and recorded in field notes.
7.4.2 Existing Conditions and Results
No Narrow Endemic Plant species were observed within the Project Footprint during the August 2021 or the April 2022 surveys. Based on the lack of suitable habitat and lack of observation during the April 20, 2022 focused rare plant survey, Narrow Endemic Plant species are not expected to occur within the Project Footprint. Appendix C details the analysis of habitat onsite for these species.
7.4.3 Impacts
No impacts are expected to occur to Narrow Endemic Plant species.
7.4.4 Mitigation
Impacts to Narrow Endemic Plant species are not anticipated; therefore, no mitigation is proposed.

7.5 Additional Survey Needs and Procedures (Section 6.3.2)
7.5.1 Criteria Area Plant Species
The Project does not fall within the mapped survey area for Criteria Area Plant Species.
7.5.2 Amphibians
The Project does not fall within the mapped survey area for amphibian species.
7.5.3 Burrowing Owl
Projects within the MSHCP Burrowing Owl Survey Area are subject to the MSHCP burrowing owl survey requirements. The majority of the Project is within the MSHCP Burrowing Owl Survey Area (Figure 9).
7.5.3.1 Methods
The burrowing owl assessment followed the guidelines identified in Burrowing Owl Survey Instructions for the Western Riverside County Multiple Species Habitat Conservation Plan Area (County of Riverside 2006). The methods employed are described in further detail in Section 4.2.2 of this Biological Technical Report and in the burrowing owl survey report, provided as Appendix D.
7.5.3.2 Existing Conditions and Results
As described in Section 5.2.1 and Appendix D, no burrowing owl or active signs thereof (e.g., active burrows, whitewash, pellets, etc.) were observed during the focused surveys conducted within the Study Area. Suitable burrows were observed within the Study Area during the surveys. The burrows depicted on Figure 10 are considered potentially suitable (>4 inches in diameter) for burrowing owls.
7.5.3.3 Impacts
No burrowing owl, nor signs thereof were observed within the burrowing owl survey area; therefore, impacts to burrowing owl are not anticipated.
7.5.3.4 Mitigation
Although burrowing owls were not observed within the Study Area during the July/August 2021 and March/April surveys, the Project Footprint contains habitat suitable for burrowing owl. A preconstruction survey will be conducted within 30 days prior to ground disturbance of the property including vegetation clearing, clearing and grubbing, tree removal, or site watering. If burrowing owl have colonized the Project Footprint prior to initiation of construction, the Project proponent will immediately inform the City and Wildlife Agencies and will need to prepare a Burrowing Owl

Protection and Relocation Plan a well as a Determination of Biologically Equivalent or Superior Preservation (DBESP) for approval by the City and the Wildlife Agencies prior to initiating ground disturbance. Additionally, if ground-disturbing activities occur, but the site is left undisturbed for more than 30 days, a pre-construction survey will again be necessary to ensure burrowing owl have not colonized the site since it was last disturbed. If burrowing owl are found, the same coordination described above will be necessary.
7.5.4 Mammals
The proposed Project does not fall within a mapped survey area for mammals.
7.6 Information on Other Species
7.6.1 Delhi Sands Flower Loving Fly
Delhi soil types are not mapped within the proposed Project Footprint, and therefore, no surveys are required for the Delhi sands flower-loving fly.
7.6.2 Species Not Adequately Conserved
Species listed in Table 9-3 (REQUIREMENTS TO BE MET FOR 28 SPECIES PRIOR TO INCLUDING THOSE SPECIES ON THE LIST OF COVERED SPECIES ADEQUATELY CONSERVED) of the MSHCP were evaluated for potential to occur within the Project Footprint and are included in Appendix C.
Of the species listed in Table 9-3, only one species exhibited at least a moderate potential to occur within the Project Footprint. Grasshopper sparrow has a moderate potential to occur due to the presence of suitable foraging habitat, however, the Project Footprint is regularly mowed/disked and consists mostly of non-native grass species. The loss of approximately 34 acres of foraging habitat for grasshopper sparrow would not decrease populations below self-sustaining levels given the availability of habitat remaining in the region; therefore, no mitigation is proposed. Individuals are expected to move to adjacent habitat during construction activities; therefore, there would be no direct mortality on the species.
The remaining species listed in Table 9-3 are not expected to occur on the Project Footprint due to the lack of suitable habitat or the site is outside the known elevation range for the species.
7.7 MSHCP Consistency Determination
The Project would be consistent with the MSHCP based on the analysis and determinations made in this Section 7.0. The Project Footprint is not located within or near an MSHCP Criteria Cell, Cell Group, or PQP land. The Project Footprint also lacks MSHCP Section 6.1.2 riparian/riverine resources, evidence of ponding water and vernal pools, and presence of sensitive vegetation communities. None of the six Narrow Endemic Plant species are expected to occur within the

Project Footprint based on the lack of suitable habitat. The Project is not located within an MSHCP Amphibian, Mammal, or Criteria Area Plant Species Survey Area; therefore, no surveys were required. The majority of the Project is within the MSHCP Burrowing Owl Survey Area, therefore, a Habitat Assessment and focused surveys for burrowing owl were conducted. No burrowing owl or active signs thereof were detected within or near the Project Footprint. A 30-day preconstruction survey for burrowing owl will be conducted prior to the initiation of construction to ensure protection for this species and compliance with the conservation goals as outlined in the MSHCP. Based on the analysis above, the Project is consistent with Sections 6.1.2, 6.1.3, and 6.3.2 of the MSHCP. No Determination of Biologically Equivalent or Superior Preservation (DBESP) mitigation plan is required. The Project would be required to pay all applicable MSHCP development impact fees.

8.0 CUMULATIVE IMPACTS
Cumulative impacts are defined as the direct and indirect effects of a proposed project which, when considered alone, would not be deemed a substantial impact, but when considered in addition to the impacts of related projects in the area, would be considered significant. “Related projects” refers to past, present, and reasonably foreseeable probable future projects, which would have similar impacts to the proposed Project. CEQA deems a cumulative impact analysis to be adequate if a list of “related projects” is included in the EIR or the proposed project is consistent with an adopted general, specific, master, or comparable programmatic plan [Section 15130(b)(1)(B)]. CEQA also states that no further cumulative impact analysis is necessary for impacts of a proposed project consistent with an adopted general, specific, master, or comparable programmatic plan [Section 15130(d)].
Although the Project would result in the loss of approximately 34 acres of land comprised mostly of herbaceous non-native forbs/grasses, the MSHCP was developed to address the comprehensive regional planning effort and anticipated growth in the County of Riverside. The proposed project has been designed and mitigated to remain in compliance with all MSHCP conservation goals and guidelines and therefore will not result in an adverse cumulative impact.

9.0 BEST MANAGEMENT PRACTICES
The Western Riverside MSHCP Volume 1, Appendix C outlines standard BMPs which are intended in part to reduce impacts to plant communities, special status plant and wildlife species, and jurisdictional waters. As the Project Footprint is located within the MSHCP boundary, the Project will be required to comply with applicable standard BMPs found in Appendix C of the MSHCP. The Project will comply with the following, which are based on the standard MSHCP BMPs:
1. A condition shall be placed on grading permits requiring a qualified biologist to conduct a training session for project personnel prior to grading. The training shall include a description of the species of concern and its habitats, the general provisions of the Endangered Species Act (Act) and the MSHCP, the need to adhere to the provisions of the Act and the MSHCP, the penalties associated with violating the provisions of the Act, the general measures that are being implemented to conserve the species of concern as they relate to the project, and the access routes to and Project Footprint boundaries within which the project activities must be accomplished.
2. Water pollution and erosion control plans shall be developed and implemented in accordance with RWQCB requirements.
3. The footprint of disturbance shall be minimized to the maximum extent feasible.
Access to sites shall be via pre-existing access routes to the greatest extent possible.
4. The upstream and downstream limits of projects disturbance plus lateral limits of disturbance on either side of the stream shall be clearly defined and marked in the field and reviewed by the biologist prior to initiation of work.
5. Projects should be designed to avoid the placement of equipment and personnel within the stream channel or on sand and gravel bars, banks, and adjacent upland habitats used by target species of concern.
6. Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of riparian identified in MSHCP Global Species Objective No. 7.
7. When stream flows must be diverted, the diversions shall be conducted using sandbags or other methods requiring minimal instream impacts. Silt fencing of other sediment trapping materials shall be installed at the downstream end of construction activity to minimize the transport of sediments offsite. Settling ponds where sediment is collected shall be cleaned out in a manner that prevents the sediment from reentering the stream. Care shall be exercised when removing silt fences, as feasible, to prevent debris or sediment from returning to the stream.
8. Equipment storage, fueling, and staging areas shall be located on upland sites with minimal risks of direct drainage into riparian areas or other sensitive habitats. These

designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat. Necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. Project related spills of hazardous materials shall be reported to appropriate entities including but not limited to applicable jurisdictional city, USFWS, CDFW, and RWQCB and shall be cleaned up immediately and contaminated soils removed to approved disposal areas.
9. Erodible fill material shall not be deposited into water courses. Brush, loose soils, or other similar debris material shall not be stockpiled within the stream channel or on its banks.
10. The qualified project biologist shall monitor vegetation clearing to ensure that practicable measures are being employed to avoid incidental disturbance of habitat and species of concern outside the project Footprint.
11. The removal of native vegetation shall be avoided and minimized to the maximum extent practicable. Temporary impacts shall be returned to pre-existing contours and revegetated with appropriate native species.
12. Exotic species that prey upon or displace target species of concern should be permanently removed from the site to the extent feasible.
13. To avoid attracting predators of the species of concern, the Project Footprint shall be kept as clean of debris as possible. All food related trash items shall be enclosed in sealed containers and regularly removed from the site(s).
14. Construction employees shall strictly limit their activities, vehicles, equipment, and construction materials to the proposed project Footprint and designated staging areas and routes of travel. The construction area(s) shall be the minimal area necessary to complete the project and shall be specified in the construction plans. Construction limits will be fenced with orange snow screen. Exclusion fencing should be maintained until the completion of all construction activities. Employees shall be instructed that their activities are restricted to the construction areas.
15. The Permittee shall have the right to access and inspect any sites of approved projects including any restoration/enhancement area for compliance with project approval conditions including these BMPs.

10.0 MITIGATION RECOMMENDATIONS
The following mitigation measures are recommended to be incorporated into the Project in order to avoid, minimize, and/or mitigate for impacts to sensitive resources within the Project Footprint.
BIO-1: Preconstruction Surveys. Prior to start of ground disturbance or vegetation removal, pre-construction surveys shall be conducted to avoid impacts to avian and bat species. (a) Removal of any trees, shrubs or any other potential nesting and foraging habitat for avian and/or sensitive avian species shall be conducted outside of the nesting season to the extent practical. Alternatively, a nesting bird survey shall be conducted within three days prior to the start of work if work is to occur during the nesting bird season (January 31 – August 31). If vegetation removal occurs outside of nesting season or if no nesting birds are found, no further action is required. If active nests are identified, the biologist shall establish appropriate buffers around the nest (typically 500 feet for raptors and sensitive species, 200 feet for nonraptors/non-sensitive species). All work within these buffers shall be halted until the nesting effort is finished (i.e., the juveniles are surviving independent from the nest). The onsite biologist shall review and verify compliance with these nesting boundaries and shall verify the nesting effort has finished. Work can resume within the buffer area when no other active nests are found. Alternatively, a qualified biologist may determine that certain work can be permitted within the buffer areas and shall develop a monitoring plan to prevent any impacts while the nest continues to be active (i.e., has eggs or chicks). If vegetation clearing is not initiated within 72 hours of a negative survey during the nesting season, the nesting survey must be repeated to confirm the absence of nesting birds. (b) Trees and large shrubs shall be surveyed for the presence of special status bat species by a qualified bat biologist no more than two weeks prior to the initiation of vegetation removal or ground disturbing activities if work will begin within the maternity season (March 1 to August 31). Surveys may entail direct inspection of the trees and large shrubs or nighttime surveys as determined by the qualified biologist. If active bat roosts are present, a qualified bat biologist shall determine the species of bats present and the type of roost (i.e., day roost, night roost, maternity roost). If special-status bat species are present, a qualified bat biologist shall determine appropriate avoidance measures, which may include implementation of a construction-free buffer around the active roost.
BIO-2: A pre-construction presence/absence survey for burrowing owl within the Project Footprint where suitable habitat is present shall be conducted by a qualified biologist within 30 days prior to the commencement of ground disturbing activities including vegetation clearing, grubbing, tree removal, or site watering. If burrowing owl have

colonized the Project Footprint prior to initiation of construction, the Project proponent shall immediately inform the City and Wildlife Agencies and will need to prepare a Burrowing Owl Protection and Relocation Plan a well as a Determination of Biologically Equivalent or Superior Preservation (DBESP) for approval by the City and Wildlife Agencies prior to initiating ground disturbance. Additionally, if grounddisturbing activities occur, but the site is left undisturbed for more than 30 days, a preconstruction survey shall again be necessary to confirm burrowing owl have not colonized the site since it was last disturbed. If burrowing owl are found, the same coordination described above shall be necessary.

APPENDIX C
Special Status Species Potential Occurrence Determination
This table summarizes conclusions from analysis and field surveys regarding the potential occurrence of special status species within the Project Footprint. During the field surveys, the potential for special status species to occur within the Project Footprint was assessed based on the following criteria:
• Present: observed on the site during the field surveys, or recorded on-site by other qualified biologists.
• High potential to occur: observed in similar habitat in the region by a qualified biologist, or habitat on the site is a type often utilized by the species and the site is within the known distribution and elevation range of the species.
• Moderate potential to occur: reported sightings in surrounding region, or the site is within the known distribution and elevation range of the species and habitat on the site is a type occasionally used by or typical of the species.
• Low potential to occur: the site is within the known distribution and elevation range of the species but habitat on the site is rarely used by the species or no suitable habitat is present, or there are no known recorded occurrences of the species within or adjacent to the site.
• Absent: a focused study failed to detect the species or the site is outside the known distribution and elevation range of the species.
• Unknown: the species’ distributional/elevation range and habitat are poorly known.
Even with field surveys, biologists assess the probability of occurrence rather than make a definitive conclusion about species’ presence or absence. Failure to detect the presence of the species is not definitive and may be due to variable effects associated with fire, rainfall patterns, and/or season.
