4.13.3 Impact Analysis
a. Would the project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? (Less Than Significant Impact, No New Impact)
Construction Noise Impacts. This section summarizes the potential increase in impacts resulting from the short-term construction activities associated with the development of the proposed project compared to the prior General Plan EIR noise impact analysis. Noise generated by the construction equipment associated with the proposed project would include a combination of trucks, power tools, concrete mixers, and portable generators that when combined can reach high levels. Construction activities are expected to occur in the following stages: site preparation, grading, building construction, paving, and architectural coating. Based on the construction noise levels detailed in the Noise Impact Analysis,92 the highest anticipated noise levels during construction, occurring when the loudest equipment operates closest to the nearest sensitive receptor, would average approximately 65 dBA equivalent continuous sound level (Leq). This is below the City of Vallejo’s daytime construction noise threshold of 80 dBA Leq at all sensitive receptor locations. In addition, the project would be required to comply with noise-related provisions of the City of Vallejo Municipal Code, Chapters 12.40 and 16.502, which establish allowable hours of construction activity and prohibit construction noise that exceeds established performance standards. According to the City of Vallejo Municipal Code, Chapters 12.40 and 16.502. During construction, construction activities shall be limited to the hours of 7:00 a.m. to 6:00 p.m., Monday through Friday, and 9:00 a.m. to 6:00 p.m. on Saturdays. Construction is prohibited on Sundays and City-observed holidays, unless a special permit is issued by the City. Compliance with these existing regulatory requirements would ensure that construction activities occur only during permitted hours and would not generate excessive noise levels. Therefore, the proposed project would not result in new significant construction-related noise impacts. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

Off-Site Transportation Noise Impacts. As detailed in the Noise Impact Analysis,93 the location with the greatest chance of an off-site transportation noise impact is at the residence near the entrance to the project site and at Shady Lane and Wildflower Avenue. Assuming a typical speed of 25 miles per hour (mph), a predominantly automobile traffic mix, and no barriers, the proposed project is predicted to generate a noise level of 50.2 dBA CNEL at the nearest building façade of 196 Wildflower Avenue. Therefore, transportation associated with the proposed project would not expose existing noise-sensitive receivers to excessive noise levels, and the off-site traffic noise level impacts due to the proposed project are considered less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. Off-Site Operational Noise Impacts. Adjacent off-site land uses would potentially be exposed to stationary-source noise impacts from the proposed ground mounted air conditioning units. These units are anticipated to 92 Urban Crossroads. 2025. Vista Cove Noise Impact Analysis, City of Vallejo. April. 93 Ibid.

The analysis considered worst-case conditions, assuming 24-hour operation, seven days per week. Based on the reference noise levels detailed in the Noise Impact Analysis,94 the highest operational noise level would average 33.3 dBA Leq at the sensitive receiver locations, which would not exceed the daytime or nighttime noise level thresholds of 60 dBA Leq or 50 dBA Leq, respectively, at any receiver location. As such, the air conditioning units, which represent the primary source of operational noise, would not exceed the City’s established thresholds for residential areas. Therefore, the operational noise generated by the proposed project would not result in a substantial permanent increase in ambient noise levels in excess of local standards as the project noise impacts were within the noise impacts evaluated in the General Plan EIR. Impacts would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. b. Would the project result in generation of excessive groundborne vibration or groundborne noise levels? (Less Than Significant Impact, No New Impact) Construction. Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods used, distance to the affected structures and soil type. It is expected that ground-borne vibration from project construction activities would cause only intermittent localized effects. The proposed project’s construction activities most likely to cause vibration impacts are:Heavy Construction Equipment: Although all heavy mobile construction equipment has the potential to cause at least some perceptible vibration while operating close to buildings, the vibration is usually short-term and is not of sufficient magnitude to cause building damage.Trucks:

Trucks hauling building materials to construction sites can be sources of vibration intrusion if the haul routes pass through residential neighborhoods on streets with bumps or potholes. Repairing the bumps and potholes generally eliminates the problem.Based on the reference construction vibration levels detailed in the Noise Impact Analysis95 and the construction vibration assessment methodology published by the FTA, construction vibration velocity levels associated with the proposed project are estimated to range from less than 0.02 to 0.07 inches per second (in/sec) peak particle velocity (PPV) at the nearest adjacent off-site structure. Based on the maximum acceptable continuous vibration threshold of 0.10 in/sec PPV, the typical project construction vibration levels would not exceed the vibration thresholds at any local receiver. Additionally, since the vibration levels would be well below 0.30 in/sec PPV, there would be no structural vibration impacts.

Therefore, the project-related vibration impacts associated with construction activities are considered less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

Operation. The proposed project would not result in vibration impacts related to on-site stationary source operations because the proposed stationary equipment, ground-mounted air conditioning units, would not generate perceptible vibration levels. These units are typical residential heating, ventilation, and air conditioning (HVAC) systems designed for continuous, low-vibration operation and would be installed on vibration-isolating pads in accordance with standard construction practices.In addition, the proposed project would not result in vibration impacts from projectrelated traffic on site or on adjacent roadways. Project-related vehicle trips would consist of 94 Urban Crossroads. 2025. Vista Cove Noise Impact Analysis, City of Vallejo. April. 95 Ibid.

The rubber tires and suspension systems of these vehicles effectively dampen vibration, and such activity is not typically associated with perceptible or damaging levels of groundborne vibration. Based on a reference vibration level, structures located more than 20 feet from the roadways used by project-related traffic would experience vibration levels well below the commonly used threshold for structural damage.

Therefore, vibration levels generated from stationary equipment and project-related traffic would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.
c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? (No Impact, No New Impact)
Aircraft flyovers may be audible on the project site due to aircraft activity in the vicinity. The nearest airports to the project site are Buchanan Airfield, located approximately 10 miles to the southeast, and Napa County Airport, located approximately 10 miles to the north of the project site. Because the project site is not within the vicinity of a private airstrip or an airport land use plan or within 2 miles of a public airport or public use airport, the proposed project would not expose people residing or working in the project area to excessive noise levels. There would be no impacts. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

4.14.1 Prior Environmental Analysis
Chapter 4.12 of the General Plan EIR analyzed impacts related to population and housing associated with build out of the General Plan and determined that build out of the General Plan would result in less than significant impacts related to population and housing. No mitigation measures were prescribed. There are no General Plan goals, policies, or actions related to population and housing which would be applicable to the proposed project.

4.14.2 Background
The proposed project would include the construction of 51 single-family residential units and associated improvements, including new private internal roadways and alleys, fencing, landscaping, and common open space areas on vacant, undeveloped land. No residential units currently exist at the project site. Based on the City of Vallejo’s average household size (2019–2023) of 2.79 persons per household,96 the proposed project would increase the local population by approximately 143 persons.

4 P:\2024\20241845 CYV Vista Cove Project\PRODUCTS\Subsequent MND\Public Review\Vista Cove MND_Public Review.docx (11/05/25) -124 approximately 122,807 persons as of July 1, 2023.98 The anticipated population growth associated with the proposed project represents less than a 1 percent increase in the city’s current population.

The City’s population is projected to grow by 24,826 persons to a total of 142,744 persons by 2040.99 The proposed project represents approximately 0.6 percent of the population growth anticipated through 2040.

Because the project would create new housing, project implementation would increase the population in the area. This population growth, however, would not be considered substantial or unplanned because the proposed project is consistent with the City’s General Plan land use and zoning designations for the site and would thus be consistent with the growth assumed for build out of the General Plan. Therefore, the proposed project would not result in substantial unplanned population growth in the area, and this impact would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. b. Would the project displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? (Less Than Significant Impact, No New Impact) The project site is currently vacant, undeveloped land consisting of undulating hills and flat areas covered primarily with non-native annual grassland and scattered mature trees. No residential uses currently exist within the project site. Because the proposed project includes the construction of 51 single-family residential units, the proposed project would contribute to the City’s housing supply.

Therefore, the proposed project would not result in the displacement of people or housing and would not require the construction of replacement housing elsewhere, and impacts would be less than significant.

4.15.2 Background
The project site is located within the City of Vallejo and is served by the following existing public services.

4.15.2.1 Fire Protection
Fire suppression, emergency medical and rescue services, and other life safety services are provided to the project area and the site by the Vallejo Fire Department (VFD). The closest active fire station to the project site is Vallejo Fire Station 24 at 1005 Oakwood Avenue, approximately 1.7 miles northwest of the project site. Fire Station 24 houses an engine company of three firefighters on each shift.100

4.15.2.2 Police Protection
The Vallejo Police Department (VPD) provides law enforcement services to the City of Vallejo. VPD has one station within the city limits, located at 111 Amador Street approximately 2.5 miles northwest of the project site.101

4.15.2.3 Schools
The project site is within the boundaries of the Vallejo City Unified School District (VCUSD). The VCUSD operates 20 schools, including 10 elementary schools serving kindergarten through 5th grade; 5 schools serving kindergarten through 8th grade; one middle school serving grades 6 through 8, two high schools serving grades 9 through 12; one adult school, and one alternative school.

a. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:
i. Fire protection? (Less Than Significant Impact, No New Impact) Fire suppression, emergency medical and rescue services, and other life safety services are provided to the project area and the site by the Vallejo Fire Department (VFD). The VFD also provides a range of non-emergency services, including public education, fire prevention programs, and permit inspection services. The VFD also participates in countywide and Statewide mutual-aid programs with fire agencies in Solano County, Napa County, and Contra Costa County. There are six fire stations within Vallejo. The closest fire station to the project site is Vallejo Fire Station 26 at 1335 Fulton Avenue, approximately 0.6 mile west of the project site. However, Fire Station 26 is currently closed due to budget cuts. The closest active fire station to the project site is Vallejo Fire Station 24 at 1005 Oakwood Avenue, approximately 1.7 miles northwest of the project site. Fire Station 24 houses an engine company of three firefighters on each shift. Current VFD staffing and equipment levels allow for simultaneous dispatch of up to three engines, one truck, one paramedic unit, and the Battalion Chief.103
The VFD currently meets its response time goals in much of the city, where incidents are generally clustered in proximity to higher-call-volume fire stations. In outlying areas of the city, steep terrain and a winding street network make maintaining response time goals more challenging. Mutual-aid agreements with neighboring jurisdictions help ensure adequate response times in the outlying areas. Currently, VFD can dispatch firefighters to areas farthest from any station within 12 minutes of call receipt, which is generally adequate to stop serious fires from spreading to adjoining buildings and to provide medical treatment for noncritical patients.104 Planned growth under the General Plan would increase calls for fire protection services in Vallejo.

The proposed project is consistent with the site’s General Plan designations and does not represent unplanned growth given that the project site would be developed consistent with applicable land use and zoning designations. As noted in Section 4.14, Population and Housing, the proposed project would result in an incremental increase in the population of the city and therefore incrementally increase the demand for emergency fire services and emergency medical services. However, the proposed project would be required to comply with all applicable codes for fire safety and emergency access.

VFD would review the site plans, fire truck access, and site fire flow design for the proposed project to ensure that adequate emergency access is provided prior to issuance of a building permit. Project design features incorporated into the structural design and layout of the residential units would keep 103 Vallejo, City of. 2016. Op. cit. 104 Ibid.

For example, the project would be constructed in accordance with the current CBC, which requires all on-site structures to incorporate construction techniques and materials such as roofs, eaves, exterior walls, vents, appendages, windows, and doors that are resistant to and/or perform at high levels against ignition during exposure to fires.

Vehicular access to the project site would be provided by one full-access residential street through an established community to the west of the intersection of Shady Lane and Wildflower Avenue, and the proposed project would include new internal residential streets. The proposed roadways would be developed to City and Fire Code standards to allow emergency vehicles ease of access and maneuverability.

Furthermore, the project sponsor would be required to pay public facilities impact mitigation fees105 used to fund capital costs associated with constructing new public facilities and purchasing equipment for new public facilities. These fees are one-time charges applied to new development and are imposed to raise revenue for the construction or expansion of capital facilities located outside of project boundaries of a new development that benefit the area. Public facilities impact mitigation fees enable the City to collect fair-share fees from new development projects to fund new infrastructure and services. These fees are collected for specific infrastructure needs and are deposited into different accounts representing these requirements. Payment of public facilities impact mitigation fees commensurate with the increased demand for services in Vallejo would offset any increase in demand for fire protection services.

Development of the proposed project would not cause fire staffing, facilities, or equipment to operate at a deficient level of service. The VFD would continue providing services to the project site and would not require additional firefighters to serve the proposed project. The construction of a new or expanded fire station would also not be required. The potential increase in demand for service is not expected to adversely affect existing response times to the site or within Vallejo.

Therefore, the proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities or the need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts in order to maintain acceptable service ratios, response times, or other performance objectives for fire protection, and this impact would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. ii. Police protection? (Less Than Significant Impact, No New Impact) The Vallejo Police Department (VPD) provides law enforcement services to the City of Vallejo.

Property crimes, including burglary, larceny, and robbery, account for most of the crime in Vallejo, and at times exceed the Bay Area and California averages.106 The project site is located adjacent to an established residential area of the city, which is already served by the VPD.

VPD is organized into eight units providing field operations and support services. The Communications and Dispatch Unit provides public safety communications for police and fire, answering 9-1-1 calls and dispatching police, fire, and medical responses in the greater Vallejo area.

The Community Services Unit, established at the end of 2013, addresses quality-of-life crimes in the city and provides assistance and support to Neighborhood Watch groups as well as public education and outreach services in the community.107
Planned growth under the General Plan would increase calls for police protection service in the city.

The proposed project could result in an incremental increase in the demand for police protection services; however, the proposed project is consistent with the site’s General Plan designation and does not represent unplanned growth. As previously discussed, development of the proposed project would increase the population on the project site and incrementally increase demand for emergency police services. However, the VPD would continue to provide service to the project site and would likely not require additional officers to serve the proposed project, considering the negligible increase in population that would result from the proposed project (less than 1 percent of the City’s current population). Furthermore, the project sponsor would be required to pay public facilities impact mitigation fees108 used to fund capital costs associated with constructing new public facilities and purchasing equipment for new public facilities. Payment of public facilities impact mitigation fees commensurate with the increased demand for services in the city would offset any increase in demand for police protection services.

The construction of new or expanded police facilities would not be required to serve the proposed project. Therefore, the proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, or the need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts in order to maintain acceptable service ratios, response times, or other performance objectives for police protection.

School, Hogan Middle School, and Jesse Bethel High School. As shown in Table 4.15.A, enrollment in the VCUSD, Glen Cove Elementary School, Hogan Middle School, and Vallejo High School has decreased in the last 3 school years.

The estimated number of students the proposed project would generate is derived by multiplying the number of students per dwelling unit (the student yield factor) by the number of dwelling units in the proposed project (51 new units). The California State Allocation Board Office of Public School Construction reports that the Statewide student yield factor of 0.7 student per dwelling unit is applicable for unified school districts.109 Applying the Statewide average student yield factor, the proposed project would generate 36 students. The proposed project is consistent with the site’s General Plan designations and does not represent unplanned growth given that the project site would be developed consistent with applicable land use and zoning designations. The EIR prepared for the General Plan determined that on a district-wide level the projected growth under implementation of the General Plan would not exceed school capacity.110 In addition, under State law, the project sponsor would be required to pay school impact fees per SB 50, prior to the issuance of a building permit, to mitigate for impacts to school facilities. Therefore, the project would not require the construction of new or physically altered educational facilities, the construction of which could result in an environmental impact. Impacts associated with the need to expand educational services and facilities in order to maintain acceptable levels of service would be less than significant.

No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. iv. Parks? (Less Than Significant Impact, No New Impact) The Greater Vallejo Recreation District (GVRD) currently operates 33 parks with various amenities throughout the city, including: 20 neighborhood parks, 10 community parks, 6 special-purpose parks, and 4 community centers. It also manages over 1,000 acres of public land within Vallejo and some surrounding areas.111 The City has established a parkland standard of 4.25 acres per 1,000 people. 109 California Office of Public School Construction. 2019.

P:\2024\20241845 CYV Vista Cove Project\PRODUCTS\Subsequent MND\Public Review\Vista Cove MND_Public Review.docx (11/05/25) Vallejo currently has 7.90 acres of parkland per 1,000 residents. Therefore, the City is currently exceeding its adopted parkland service standard.112
The proposed project involves the construction of 51 single-family residences and would induce minor population growth in the area. The increase in residents within the area may result in an incremental increase in demand for and use of local parks and recreation areas. However, this increase in use is not expected to adversely affect the physical conditions of local and regional open space areas or recreational facilities or require the provision of new parks or facilities because the proposed project is anticipated to increase the city’s population by less than 1 percent. The closest parks to the project site are Benicia State Recreation Area (located approximately 0.3 mile southeast of the project site), Glen Cove School Park (located approximately 0.5 mile southwest of the project site), and Glen Cove Waterfront Park (located approximately 0.9 mile southwest of the project site).

Benicia State Recreation Area includes trails, picnic areas, and campsites. Glen Cove School Park includes a children’s play area, tennis and pickleball courts, picnic tables, and a sports field. Glen Cove Waterfront Park includes trails that connect to the San Francisco Bay Trail.

The proposed project would include 9.74 acres of undisturbed open space and 3.55 acres of common open space, including two bioretention areas, walkways, a loop walk around a flexible-use turf area, and a vista overlook for residents. The proposed single-family residences would also include private front and rear yards. However, the project does not include any outdoor areas intended for public use. The construction of these private facilities is expected to reduce the strain of use on existing neighborhood parks and recreational facilities.

Because the population increase due to the proposed project is not substantial enough to cause a strain on parks and facilities, the proposed project would not result in a substantial increase in demand for park or recreation services in the vicinity such that new facilities would be required to serve the project. Furthermore, new residential development is required to pay park impact fees, as required by Chapter 3.18 of the City’s Municipal Code, to generate revenue to be used for the acquisition of land for parks, recreational facilities, or open space; for improvement thereto; or for reasonable consultation fees, feasibility studies, environmental review, and professional services performed in connection with acquisition or improvement of parks, recreational facilities, or open space.113 Therefore, the proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities or the need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts in order to maintain acceptable service ratios, response times, or other performance objectives for recreation, and this impact would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. 112 Vallejo, City of. 2016.

4.16.1 Prior Environmental Analysis
Chapter 4.11 of the General Plan EIR analyzed impacts on parks and recreation associated with build out of the General Plan and determined that build out of the General Plan would result in less than significant impacts related to parks and recreation because the City exceeds its current parkland standard and existing State and local regulations would serve to ensure that future development would not result in significant impacts related to parks and recreation. No mitigation measures were prescribed. However, the General Plan includes the following policies and actions related to recreation which would be applicable to the proposed project:
○ Policy CP-3.4 Parks. Plan for and provide parkland and facilities to support Vallejo’s recreational needs.
■ Action CP-3.4A: Maintain a standard of 4.25 acres of parkland per thousand residents and continue to require that new residential development make a fair share contribution to future parks development.

4.16.2 Background
The Greater Vallejo Recreation District (GVRD) currently operates 33 parks with various amenities throughout the city, including: 20 neighborhood parks, 10 community parks, 6 special-purpose parks, and 4 community centers. It also manages over 1,000 acres of public land within Vallejo and some surrounding areas.114 The closest parks to the project site are Benicia State Recreation Area (located approximately 0.3 mile southeast of the project site), Glen Cove School Park (located approximately 0.5 mile southwest of the project site), and Glen Cove Waterfront Park (located approximately 0.9 mile southwest of the project site).

4.16.3 Impact Analysis
a. Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? (Less Than Significant Impact, No New Impact) As discussed in Section 4.15, Public Services, residents of the proposed project would be expected to use local parks and community facilities within Vallejo and the surrounding neighborhoods, as well as regional recreational facilities. Although the proposed project would incrementally increase use of these facilities, this minor increase in use is not expected to result in substantial physical deterioration of local parks, trails, and community centers. As discussed in Section 4.14, Population and Housing, the anticipated population growth associated with the proposed project represents less than a 1 percent increase in the city’s current population. Based on the estimated population increase, these facilities are anticipated to have the capacity to serve this increase in demand.

The project also includes the construction and development of various outdoor amenities within the project site, including 9.74 acres of undisturbed open space and 3.55 acres of common open space, including two bioretention areas, walkways, a loop walk around a flexible-use turf area, and a vista overlook for residents. The proposed single-family residences would also include private front and rear yards. The construction of these private facilities is expected to reduce the strain of use on existing neighborhood parks and recreational facilities. Furthermore, new residential development is required to pay park impact fees, as required by Chapter 3.18 of the City’s Municipal Code, to generate revenue to be used for the acquisition of land for parks, recreational facilities, or open space; for improvement thereto; or for reasonable consultation fees, feasibility studies, environmental review, and professional services performed in connection with acquisition or improvement of parks, recreational facilities, or open space. 115 Therefore, the proposed project would have a less than significant impact on existing parks or other recreational facilities. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.
b. Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? (No Impact, No New Impact)
As previously discussed, the proposed project would include the construction and development of various outdoor amenities within the project site, including 9.74 acres of undisturbed open space and 3.55 acres of common open space, including two bioretention areas, walkways, a loop walk around a flexible-use turf area, and a vista overlook for residents. These private amenities would be for use by residents of the development and not for public recreational use. The proposed project does not include or require the construction or expansion of existing public recreational facilities, which might have an adverse physical effect on the environment, and no impact would occur. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. 115 Vallejo, City of. n.d.-b.

d. Result in inadequate emergency access?

4.17.1 Prior Environmental Analysis
Chapter 4.14 of the General Plan EIR analyzed impacts to transportation and traffic associated with build out of the proposed project and determined that development would conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system and freeway and highway facility impacts would be significant. The General Plan EIR prescribed Mitigation Measure TRANS-1a.1, requiring the City work to minimize congestion in the two-lane road portion of Sonoma Boulevard; General Plan EIR Mitigation Measure TRANS1a.2, requiring the City make roadway improvements to Railroad Avenue; and General Plan EIR Mitigation Measure TRANS-1b, requiring the City work with the Solano Transportation Authority and Caltrans to study, identify, program, and build capacity improvements on SR-37 between I-80 and west of the Mare Island interchange. None of these mitigation measures would be applicable to the proposed project as the project site is not located in the vicinity of any of the proposed transportation improvements. Even with implementation of these mitigation measures, the impacts were determined to be significant and unavoidable.

Additionally, the General Plan includes the following policies and actions related to transportation and traffic which would be applicable to the proposed project:
• Goal MTC-2: Mobile Community: Enhance local transportation options and maintain a safe, convenient, and sustainable local transportation system. ○ Policy MTC-2.1: Safety First: Prioritize pedestrian, bicycle, and automobile safety over traffic flow.
○ Policy MTC-2.3: Emergency Response Routes: Ensure adequate emergency vehicle access in all areas of Vallejo.
■ Action MTC-2.5B: Set vehicle Level of Service of E or better as an advisory standard to be considered along with, but not to override, metrics for pedestrian, bicycle, transit,

○ Policy MTC-2.7: Complete Streets: Increase accessibility for and use of streets by pedestrians, bicyclists, and transit riders.
■ Action MTC-2.8C: As part of the site plan approval process, require development to provide services from a menu of transportation demand management (TDM) strategies that will reduce VMT.
○ Policy MTC-2.11: Sustainable Transportation: Ensure that circulation improvements can be operated and maintained within existing and future resource limitations. • Goal MTC-3: Interconnected Community: Improve connections within and between Vallejo’s neighborhoods for all travel modes.
○ Policy MTC-3.1: Coordinated Transportation Planning: Ensure that improvements to the transportation network support a land use pattern that connects the community and facilities travel among Vallejo’s neighborhoods.

4.17.2 Background
The following discussion is based on the findings from the Transportation Analysis116 prepared for the proposed project, which is included in Appendix I of this Initial Study.

4.17.2.1 Existing Circulation System
The 20.13-acre project site is located at the northeast corner of Shady Lane and Wildflower Avenue (Assessor’s Parcel Numbers [APNs] 0079-171-170 and 0079-120-100) in southeastern Vallejo, west of the eastern boundary with the city of Benicia, in an area consisting primarily of residential, recreational, and public and semi-public uses. Regional vehicular access to the project site is provided by Interstate 780 (I-780), located immediately north of the project site. I-780 is an eastwest route between Vallejo and Benicia, connecting Interstate 80 (I-80) to Interstate 680 (I-680) in Benicia. I-780 is a four-lane divided facility (two lanes in each direction), with a speed limit of 65 mph.117 The route serves an annual average daily traffic (AADT) volume of 55,000 vehicles through 116 LSA Associates, Inc. 2025.

Direct local access to the project site is via Shady Lane and Wildflower Avenue that border the site immediately to the southwest. Shady Lane and Wildflower Avenue and other roadways in the nearby vicinity of the project site are classified as local streets, which are defined as providing direct access to property, and typically have higher intersection spacing and lower speeds than the other roadway classes.119 Glen Cove Parkway, which is located approximately 0.5 mile west of the project site, is the nearest classified collector street. Collector streets provide connectivity within the city, linking local roads to arterials. Collectors, along with local streets, provide the highest level of access from private property driveways. Collectors typically have lower speeds than arterials, and more closely spaced intersections than arterials.120

4.17.2.2 Existing Transit System
Solano County Transit (Soltrans) provides local bus, regional express bus, and Americans with Disabilities Act (ADA) paratransit bus services in Vallejo. Local bus service is supplemented by limited-service routes for school days and regional express bus service connecting to the Contra Costa communities of El Cerrito, Pleasant Hill, and Walnut Creek and the Fairfield Transportation Center in Fairfield. Express bus services also provide connections to San Francisco Bay Area Rapid Transit (BART), AC Transit, County Connection, Fairfield and Suisun Transit, Golden Gate Transit, San Francisco Bay Ferry, Vine Transit, and WestCAT. The project area is served by SolTrans Routes 3 and 8, with the transit stops located approximately 0.5 mile to the west along Glen Cove Parkway, which are accessible to and from the project site via sidewalks along nearby local streets. The Amtrak station in Vallejo is located approximately 4 miles northwest of the project site and the Vallejo Ferry Terminal, which offers ferry service between Vallejo and San Francisco, is located approximately 3.5 miles northwest of the project site.

4.17.2.3 Existing Bicycle and Pedestrian System
Pedestrian facilities include sidewalks, pedestrian signal phases, curb ramps, curb extension, and various streetscape amenities such as lighting and benches. In general, a network of sidewalks, crosswalks, pedestrian signals, and curb ramps provide access for pedestrians in the vicinity of the proposed project site.

Bikeways in the city are classified into the following categories:
• Class I – off-street bike paths
• Class II – on-street bike lanes marked by pavement striping and signage • Class III – on-street designated bike routes that share the road with motorized vehicles 118 City of Vallejo. 2016.

4.17.3 Impact Analysis
a. Would the project conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? (Less Than Significant Impact, No New Impact)
The proposed project would include the construction of 51 single-family residential dwelling units and undeveloped open space on 10 acres within a 20.13-acre project site at the northeast corner of Shady Lane and Wildflower Avenue. The proposed project would be accessed via one full access residential street off the intersection of Shady Lane and Wildflower Avenue. The proposed project would include new internal residential streets with parking on one side and an attached sidewalk.

Roadway Analysis.The City of Vallejo Traffic Impact Analysis/Study Guidelines122 were adopted to identify the traffic impacts to traffic operation and safety and to provide the standard requirements for the preparation of a traffic study. These guidelines state that projects likely to add 500 or more daily two-way trips or 100 or more peak period two-way trips would require a traffic analysis. The trip generation for the proposed project was developed using rates from the Institute of Transportation Engineers (ITE) Trip Generation Manual (2021)123 for Land Use Code 210 (SingleFamily Detached Housing), as shown in Table 4.17.A, below.

Similarly, the 2023 Solano County Congestion Management Program (CMP)124 states that projects are reviewed if they will cause a net increase of 100 or more PM peak-hour vehicle trips. The proposed project traffic is below this threshold for review.

Action MTC 2.5-B of the City’s General Plan sets a level of service (LOS) standard of E or better to be considered along with, but not to override, metrics for pedestrian, bicycle, transit, and emergency access performance. As such, an analysis was prepared to identify the project’s potential to affect the operation of the intersection of Glen Cove Parkway/Robles Way. The signalized intersection of Glen Cove Parkway/Robles Way is one of the access points for the existing neighborhood adjacent to the proposed project and an intersection that traffic for most of the Glen Cove community passes through. It is anticipated that all vehicles for the proposed project will use the intersection of Glen Cove Parkway/Robles Way. LSA contracted with an independent data collection company to collect traffic volume data during the morning and afternoon peak commute periods at this intersection on Thursday, August 22, 2024. All project trips were distributed to/from the north and were added to the existing traffic volume data for the project scenario. Table 4.17.B summarizes the results of the LOS analysis. LOS worksheets are provided in Appendix I. As Table 4.17.B shows, the intersection operates at satisfactory LOS B in existing conditions and traffic from the proposed project would not change the delay at this intersection such that the LOS of the intersection would be reduced or degraded below LOS E, consistent with General Plan Policy MTC-2.5.

Because the project would generate fewer trips than the threshold for review established by the City and in the CMP, and because project traffic was not found to degrade the operation of the intersection of Glen Cove Parkway/Robles Way to below LOS E, it is determined that the project does not have the potential to significantly affect roadway operations, and the project would not conflict with General Plan policies regarding LOS. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

4 P:\2024\20241845 CYV Vista Cove Project\PRODUCTS\Subsequent MND\Public Review\Vista Cove MND_Public Review.docx (11/05/25) -140 Transit, Pedestrian, and Bicycle Facilities. The potential impacts of the project on pedestrian, bicycle and transit are described below.Pedestrian Facilities. According to the United States Census Bureau,125 pedestrian trips comprise approximately 1.6 percent of the total commute mode share in the City of Vallejo. The proposed project also would generate pedestrian trips to/from transit stops, recreation areas, and employment centers. The volume of pedestrian trips generated by the project would not exceed the carrying capacity of the sidewalks and crosswalks nearby.In the immediate project vicinity, there are sidewalks along Wildflower Avenue and Shady Lane up to the intersection with Robles Way and along Robles Way. There are marked crosswalks, pedestrian push buttons, and pedestrian signals provided at the signalized intersection of Robles Way with Glen Cove Parkway.

Although very few pedestrian trips are anticipated to and from the site, the City’s General Plan policies encourage non-motorized travel, including walking, bicycling, and transit.

Consistent with existing City policies, the proposed project would provide minimum 4.5-footwide pedestrian pathways to connect the single-family homes to the common open space areas within the developed portion of the proposed project and adjacent neighborhood. The proposed project would not disrupt existing pedestrian facilities and would not interfere with planned pedestrian facilities. Therefore, the proposed project would have a less than significant impact on pedestrian facilities. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

Bicycle Facilities. United States Census Bureau data indicate that bicycle trips comprise approximately 1.7 percent of the total commute mode share in the City of Vallejo.126 The low volume of bicycle trips generated by the project would not exceed the bicycle-carrying capacity of streets surrounding the site, and the increase in bicycle trips would not by itself require new off-site bicycle facilities. The nearest designated bikeway to the project area consists of a Class II Bikeway along Glen Cove Parkway, approximately 0.5 mile west of the project site. The proposed project, by itself, would not require additional bicycle service to the area. The proposed project would not preclude, modify, or otherwise affect existing or proposed bicycle projects or policies identified in the General Plan Transportation Element. Therefore, the proposed project would have a less than significant impact on bicycle facilities. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

Transit Service. The project area is served by SolTrans Routes 3 and 8, with the transit stops located approximately 0.5 mile to the west along Glen Cove Parkway, which are accessible to and from the project site via sidewalks along nearby local streets. According to the United States Census Bureau, transit trips comprise approximately 5 percent of the total commute mode share in the City of Vallejo.127 In addition to commute trips, there would be additional transit trips to 125 United States Census Bureau. 2021 Census. 5-year ACS Data Table B08134: Means of Transportation to Work by Travel Time to Work.

The low volume of transit trips generated by the project would not exceed the carrying capacity of the existing transit service to the site and the proposed project would not interfere with existing transit facilities or preclude the construction of any planned transit facilities or otherwise affect existing or proposed transit projects or policies identified in the City of Vallejo General Plan. Therefore, the proposed project would have a less than significant impact on transit service. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.b. Would the project conflict or be inconsistent with CEQA Guidelines §15064.3, subdivision (b)? (Less Than Significant Impact, No New Impact) The State revised its State CEQA Guidelines in January 2019. Among those revisions, the evaluation of transportation impacts on a project’s effect on vehicle miles traveled (VMT) replaced consideration of vehicle delay and level of service (LOS). In July 2020, the City adopted the City of Vallejo CEQA Transportation Impact Analysis Guidelines, which were revised in October 2020.128 The City’s guidelines include project type screening for projects presumed to have a less than significant impact. Projects generating fewer than 110 daily vehicle trips are included as projects screened from preparing additional VMT analysis. A footnote is provided with this value that indicates the threshold ties directly to the 2018 OPR Technical Advisory. The footnote further explains that the OPR Technical Advisory notes that CEQA provides a categorical exemption for existing structures up to 10,000 square feet and that general office buildings generate or attract an additional 110-124 trips per 10,000 square feet.

However, in Cleveland National Forest Foundation v. County of San Diego (2025) 110 Cal.App.5th 948 [331 Cal.Rptr.3d 264] the Fourth Appellate District of the State of California found that reliance on the OPR Technical Advisory suggestion without evidentiary support is not valid. Indeed, in the first paragraph of the introduction to the OPR Technical Advisory it states that the document does not alter lead agency discretion and that the document should not be construed as legal advice. It should further be noted that the OPR Technical Advisory explanation for the small project threshold suggestion is related to commercial and not residential development.

As part of the transportation analysis a memorandum was prepared establishing evidentiary support for a small project threshold for residential development within the Bay Area Air District (Air District).129 That memorandum is provided in Appendix I. The evidence examined showed that the Air District has determined that development of fewer than 421 dwelling units would have a less than significant impact on regional GHG emissions. Furthermore, the project’s 481 daily trips identified in Table 4.17.A would produce GHG emissions at a level below the threshold of significance, and the project would not cause an increase in emissions that would result in a new significant impact or a substantially greater impact when compared to the City’s prior CEQA analysis for the General Plan.

The proposed project extends existing residential development and would have a less than significant impact on GHG emissions because it is a small project, and as such would not conflict or 128 City of Vallejo. 2020.

c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? (Less Than Significant Impact, No New Impact)
The design of the proposed project does not include any geometric design features or incompatible uses that could substantially increase circulation/traffic hazards. The proposed project would include the construction of 51 single-family residential dwelling units, undeveloped open space, and related infrastructure improvements. Vehicular access to the project site would be provided by one full access residential street through an established community to the west off the intersection of Shady Lane and Wildflower Avenue. The proposed project would include new internal residential streets that would be 28 feet wide curb-to-curb with parking on one side and a 4.5-foot attached sidewalk.

The project would also include private alleys which would be smaller in scale than the private residential streets and would include shared vehicular access to houses with garages fronting onto them. Private alleys would include a 33-foot public utility easement/planting easement, and a 10- foot travel way in each direction with no parking allowed. The design, construction, and maintenance of project access locations and on-site roads would be required to comply with the City’s Municipal Code and relevant City standards. As shown previously in Figure 2-2 in Chapter 2.0, Project Description, the project site is generally surrounded by residential, recreational, and public and semi-public uses. Therefore, the proposed project would not substantially increase hazards due to a geometric design feature or incompatible uses. This impact would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. d. Would the project result in inadequate emergency access? (Less Than Significant Impact, No New Impact)

4.18.1 Prior Environmental Analysis
The topic of potential impacts to tribal cultural resources with build out of the General Plan was not specifically analyzed in the General Plan EIR. Since certification of the General Plan EIR, the topic of Tribal Cultural Resources has been added as a new category to be analyzed per the CEQA Guidelines.

In addition, public agencies that prepare an EIR must comply with Assembly Bill (AB) 52, which requires public agencies to consult with any California Native American tribe that requests consultation and is traditionally and culturally affiliated with the geographic area of a proposed project. However, the General Plan EIR analyzed prehistoric and historic resources and human remains and included mitigation measures related to these resources as detailed in Section 4.5.2.

Additionally, the General Plan includes the following goals, policies, and actions related to cultural resources which would be applicable to the proposed project:
○ Policy NBE-1.9 Cultural Resources: Protect and preserve archaeological, historic, and other cultural resources.
■ Action NBE-1.9B: Maintain a dialogue with local Native American groups regarding sensitive cultural resources in Vallejo.

4.18.2 Background
The analysis of potential impacts to tribal cultural resources is based on a site-specific cultural resources assessment prepared for the proposed project, prepared by LSA in March 2025, which is included in Appendix D of this Initial Study.130 This assessment included a cultural resources records search, a review of historic-period aerial imagery and maps, and a pedestrian archaeological survey of the project site.

An archaeological records search was conducted on September 6, 2024, at the Northwest Information Center (NWIC) at Sonoma State University. The NWIC is the official repository for cultural resources records for Solano County and maintains an extensive inventory of previously recorded archaeological sites and prior survey coverage. The records search included a one-mile radius around the project site and reviewed all available documentation of prehistoric and historicperiod resources, as well as prior cultural resource surveys and excavation reports.

In February 2025, historic-period aerial photographs and topographic maps were reviewed using the Nationwide Environmental Title Research (NETR) Online database. This review provided supplemental information regarding historical land use within and surrounding the project area.

An intensive pedestrian survey of the project site was conducted on January 20, 2025, by a qualified archaeologist. The survey was performed using linear transects spaced approximately 20 to 30 meters (65.6 to 98.4 feet) apart. The entire accessible area of the project site was inspected, with particular attention given to areas containing exposed native soils, rock outcrops, and rodent disturbances. All visible ground surfaces were carefully examined for the presence of prehistoric or historic-period artifacts, features, or other cultural deposits.

4.18.2.1 Existing Environmental Setting
The project site is vacant and undeveloped and is covered primarily with non-native annual grassland and scattered mature trees. No buildings or structures are present within the project area in historic period aerial photos or as indicated on maps dating back to 1948.

The proposed project is within the traditional cultural territory of the Patwin. Tribal territories were somewhat fluid and changed over time. Like other Native American groups in Northern California, the Patwin were semi-nomadic hunter-gatherers who subsisted by exploitation of seasonably available plant and animal resources. The first written accounts of Native American groups in California were by Spanish missionaries in the late 18th century. With the Spanish intrusion came a drastic change in lifestyle for the Native Americans of California. Incorporation of the indigenous populations into the mission system involved conflict, forced labor, and relocation along with decimation by European diseases, all of which led to the disruption of native cultures and changes in subsistence and land use practices. Cattle ranches/farms were established on or near ancestral Native American villages, primarily in the major drainages conducive to horticulture and animal 130 LSA Associates, Inc. (LSA). 2025.

4.18.2.2 Sacred Lands File Search
LSA requested a Sacred Lands File (SLF) Search and Native American Contact List from the California Native American Heritage Commission (NAHC) on August 8, 2024. In its response on August 28, 2024, the NAHC indicated that the record search results were negative. However, because the absence of specific site information in the SLF does not indicate the absence of cultural resources in the project area, NAHC identified methodologies and contacts for conducting required AB 52 tribal consultation for information regarding cultural resources that could be affected by the proposed project.

4.18.2.3 Native American Consultation
In August 2024, the City provided notice of the proposed project to the Native American contacts provided by the NAHC and the tribes that had previously requested notification, pursuant to AB 52 provisions.

On October 10, 2024, the Confederated Villages of Lisjan Nation responded to the City’s notice and requested a copy of the final California Historic Resources Inventory System (CHRIS) records search, EIR, the SLF search results from the NAHC, and a copy of any additional archaeological reports. The City provided a response on February 10, 2025, providing the Confederated Villages of Lisjan Nation with the database searches and available information. No further responses were received.

The Yocha Dehe Wintun Nation reached out to request consultation on the proposed project on October 24, 2024. The City responded on November 18, 2024 and a meeting took place on December 9, 2024. As part of the consultation process, the City provided the Yocha Dehe Wintun Nation with draft Tribal Monitoring Mitigations on January 17, 2025. The City resent this information on February 13, 2025, and March 17, 2025, and no additional responses were received.

No further requests for consultation were received.

4.18.3 Impact Analysis
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:
i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? Or ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public 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. (Less Than Significant Impact with Mitigation Incorporated, No New Impact)
As discussed above under Section 4.18.1, Native American consultation was conducted by the City in compliance with AB 52. As part of the consultation process, a review of the SLF by the NAHC indicated that the results of the file search were negative. However, because the absence of specific site information in the SLF does not indicate the absence of cultural resources in the project area, NAHC identified methodologies and contacts for conducting the required AB 52 tribal consultation.

The City provided notice of the proposed project via certified mail to Native American tribal contacts provided by the NAHC as well as local Native American tribal representatives that previously requested to be notified of future projects proposed by the City in compliance with AB 52. The Confederated Villages of Lisjan Nation and the Yocha Dehe Winton Nation responded to the City’s notice and consultation with the Yocha Dehe Winton Nation occurred in January 2025.

No information regarding specific known tribal cultural resources on the project site was provided to the City. Furthermore, no human remains are known to be on the project site or are anticipated to be discovered during project construction. An archaeological pedestrian field survey of the project site was conducted on January 20, 2025, as part of the Cultural Resources Assessment completed for the proposed project. No cultural resources, including tribal cultural resources, were discovered within the project site during the field survey. The field survey indicated that there was light disturbance in some areas of the project site, where modern refuse was noted throughout the project area; however, overall visibility was generally limited by existing vegetation cover. No cultural resources were identified. Based on these results, the Cultural Resources Assessment determined that the project site has a low potential for in situ subsurface cultural resources due to the severe slopes and adjacent developments. Therefore, encountering unknown buried cultural resources, including tribal cultural resources, during project construction is unlikely.

Impacts related to accidental discovery of cultural resources or human remains are addressed in Section 4.5, Cultural Resources, and impacts were determined to be less than significant with implementation of Project Specific Mitigation Measures CUL-1 and CUL-2, which require adherence to proper procedure for the treatment of unanticipated tribal cultural resources if discovered during construction and require compliance with PRC 5097 and the State’s Health and Safety Code Section 7050.5 for the treatment of human remains or funerary/ceremonial objects.

Although no known tribal cultural resources are present at the site, the possibility for accidental discovery of such resources cannot be discounted. In the event that cultural items or human remains determined to be of Native American origin are encountered during project ground disturbing activities, Project Specific Mitigation Measure TCR-1 shall be implemented.

Project Specific Mitigation Measure TCR-1 Protocol for Discovery of Native American Cultural Items. The preferred protocol upon the discovery of
Native American human remains is to secure the
area, stop work within 25 feet of the find, cover any
exposed human remains or other cultural items and
avoid further disturbances in the area. All parties
are advised to treat the remains with appropriate
dignity, as provided in Public Resources Code (PRC)
Section 5097.98. All parties shall treat tribal
representatives and the event itself with
appropriate respect.

If, after the Confederated Villages of Lisjan Nation
Tribal representative has been granted access to
the site and it is determined that avoidance is not
feasible, an examination of the human remains will
be conducted to confirm they are human and to
determine the position, posture, and orientation of
the remains. The following procedures shall be
followed:
• All excavation in the vicinity of the human
remains shall be conducted using fine hand
tools and fine brushes to sweep loose dirt free
from the exposure.
• In order to determine the nature and extent of
the grade and its contents, controlled
excavation should extend to a full buffer zone
around the perimeter of the remains.
• To initiate the exposure, a perimeter balk
(especially, a shallow trench) should be
excavated, representing a reasonable buffer a
minimum of 10 centimeters around the
maximum extent of the known skeletal remains,
with attention to counterintuitive discoveries or
unanticipated finds relating to this or other

should be bucketed, distinctly labeled, and
screened for cultural materials.
• Excavation should then proceed inward from
the walls of the balk as well as downward from
the surface of the exposure. Loose dirt should
be scooped out and brushed off into a dustpan
or other collective device. Considerable care
should be given to ensure that human remains
are not further impacted by the process of
excavation.
• Buckets, collection bags, notes, and tags should
be fully labeled per provenience, and a
distinction should be made between samples
collected from: (1) Perimeter Balk (described
above), (2) Exposure (dirt removed in exposing
the exterior/burial plan and associations, and
(3) Matrix (dirt from the interstices between
bones or associations). Thus, each burial may
have three bags, “Burial 1 Perimeter Balk,”
“Burial 1 Exposure Balk,” “Burial 1 Matrix.”
• The following records should be compiled in the
field: (1) a detailed scale drawing of the burial,
including the provenience of and full for all
human remains, associated artifacts, and the
configuration of all associated phenomena such
as burial pits, evidence for pre-interment grave
pit burning, soil variability, and intrusive
disturbance, (2) complete a formal burial record
using the consultants proprietary form or other
standard form providing information on site #,
unit or other proveniences, level depth, depth
and location of the burial from a fixed datum,
workers, date(s), artifact list, skeletal inventory,
and other pertinent observations, (3) crew chief
and worker field notes that may supplement or
supersede information contained in the burial
recording form, and (4) photographs, including
either standard photography or high-quality

• For each burial, all Perimeter Balk soil is to be
1/8”-screened. All Exposure soil is to be 1/8”-
screened, and a minimum of one 5-gallon
bucket of excavated but unscreened Exposure
soil is to be collected, placed in a plastic
garbage bag in the bucket. All Matrix soil is to
be carefully excavated, screened as
appropriate, and then collected in plastic bags
placed in 5-gallon buckets.

field.
• Prior to any physical action related to human
remains, a designated tribal representative will
conduct prayers and blessings over the remains.

The archaeological consultant will be
responsible for insuring that individuals and

• Should all, or a sample, of any archaeological
materials collected during the data recovery
activities – with the exception of human
remains – need to be curated, an inventory and
location information of the curation facility shall

At the completion of project construction, the proposed project would not result in further disturbance of native soils on the project site and, therefore, project operations would have no potential to impact previously undiscovered tribal cultural resources or human remains.

Based on the findings of the Cultural Resources Assessment and AB 52 consultation, no known tribal cultural resources listed or eligible for listing in the California Register of Historical Resources (California Register) or in a local register exist within the project site, and there are no known tribal cultural resources on the project site. Therefore, the proposed project would not cause a substantial adverse change in the significance of a tribal cultural resource defined as 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 listed or eligible for listing in the California Register or in a local register of historical resources as defined in PRC Section 5020.1(k) or that is 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. Nevertheless, implementation of Project Specific Mitigation Measures CUL-1, CUL-2, and Project Specific Mitigation Measure TCR-1, are required to address the potential impacts to unanticipated tribal cultural resources, human remains, and associated funerary or ceremonial objects, the implementation of which would reduce impacts to less than significant with mitigation. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.

e. Comply with federal, state, and local management and reduction statutes and regulations related to solid
waste?

4.19.1 Prior Environmental Analysis
Chapter 4.15 of the General Plan EIR analyzed impacts to utilities and service systems associated with build out of the General Plan, and determined that either no impact or less than significant impacts would occur due to compliance with the Water Conservation Act, the California Plumbing Code, the City of Vallejo UWMP, San Francisco Regional Water Quality Control Board regulations, State Water Resources Control Board regulations, VFWD standards, the Integrated Waste Management Act, the CalGreen Building Code, and the City of Vallejo Municipal Code. No mitigation measures were prescribed. However, the General Plan includes the following policies and actions related to utilities and service systems which would be applicable to the proposed project:
○ Policy NBE-1.7: Green Infrastructure. Encourage the installation of green infrastructure, including tools such as permeable pavement, rain gardens, constructed wetlands, grassy swales, rain barrels and cisterns, and green roofs, to treat stormwater, attenuate floods, increase groundwater recharge, and reduce urban heat islands. ■ Action NBE-5.6D: Continue to enforce City regulations that prohibit development, grading, and land modification activities that would adversely affect the local drainage system or create unacceptable erosion impacts.

4.19.2 Background
The project site is located within an urbanized area with surrounding land uses supported by existing utility infrastructure.

4.19.2.1 Water Supply
Water service in Vallejo is provided by the City of Vallejo Water Department. The City of Vallejo updated its Urban Water Management Plan (UWMP) in 2020, and it was adopted in 2021. The City has numerous water supply sources that provide significant annual volumes of water, including: the Sacramento River watershed; the Solano Project from Putah Creek watershed, which includes Lake Berryessa; the Wild Horse Creek watershed through Lake Madigan, Lake Frey, and the Green Valley Diversion; and the Upper Suisun Creek watershed through Lake Curry. According to the UWMP, the average water use for the City’s service area is projected to be 28,111 AFY in 2025, 30,331 AFY in 2035, and 31,892 AFY in 2045. For the purposes of adequate projections, the 2020 UWMP assumed a 0.07 percent growth rate, the growth rate necessary to achieve the City’s project 2040 growth rate. The UWMP indicates the City has sufficient water supplies to meet water demands through 2045, including during multiple dry years.132

4.19.2.2 Wastewater
The VFWD provides wastewater collection and treatment services for Vallejo. VFWD owns and operates a collection system and secondary wastewater treatment facility located at 450 Ryder Street, Vallejo (Ryder WWTP). The Ryder WWTP has a treatment capacity of 15.5 million gallons per day (mgd)133 and treats an average of 10 mgd of wastewater.134

4.19.2.3 Stormwater
Under existing conditions, the project site consists entirely of pervious surface consisting primarily of grassland. There is no existing stormwater infrastructure on the project site; however, under existing conditions, the project site drains from west to east to Benicia State Park, where stormwater runoff converges and is directed to the Carquinez Strait.135

4.19.2.5 Solid Waste
Solid waste, recycling, and yard waste collection services in Vallejo, including the project site, are provided by Recology Vallejo. Solid waste from Vallejo was disposed at 18 different landfills in 2014; however, nearly 99 percent of Vallejo’s solid waste in 2014 went to the Potrero Hills Landfill or the Recology Hay Landfill.136 The Potrero Hills Landfill is located at 3675 Potrero Hills Lane in Suisun City and has a maximum permitted capacity of 83,100,000 cubic yards and a remaining capacity of 13,872,000 cubic yards as of January 2006. The landfill accepts a maximum of 4,330 tons per day and has an expected closure date of 2048.137 The Recology Hay Landfill is located at 6426 Hay Road in Vacaville and has a maximum capacity of 37,000,000 cubic yards and a remaining capacity of 30,433,000 cubic yards as of July 2010. The landfill accepts a maximum of 2,400 tons per day and has an expected closure date of 2077.138

4.19.3 Impact Analysis
a. Would the project require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? (Less Than Significant Impact, No New Impact) The project site is located within an urbanized area with surrounding land uses supported by existing utility infrastructure. Implementation of the proposed project would require the connection to existing infrastructure, which would involve ground-disturbing activities and the use of heavy machinery, among other construction activities.

Water. Water service in Vallejo is provided by the City of Vallejo Water Department. The proposed project would include the installation of a new 8-inch water main line that would connect to an existing 8-inch water main in Shady Lane at two locations for a looped system. The proposed project would connect directly to existing mains and the new water lines would be constructed in conformance with City standards. Utility installation would occur within the project footprint and there would be no impacts unique to infrastructure installation that would result in significant effects beyond those evaluated in the Initial Study.

The City of Vallejo updated its Urban Water Management Plan (UWMP) in 2020, and it was adopted in 2021. According to the UWMP, the average water use for the City’s service area is projected to be 30,331 acre-feet per year (AFY) in 2035 and 31,892 AFY in 2045.139 As discussed in Section 4.19.b, the proposed project would not substantially increase demand for water and would therefore not exceed the capacity of existing water treatment facilities.

Therefore, the impact of the proposed project on water infrastructure would be less than significant.

Wastewater. The VFWD provides wastewater collection and treatment services for Vallejo. A new 8-inch sewer lateral would connect to the existing 8-inch public sanitary sewer main line located in Shady Lane at the northwestern corner of the project site. The project would also include the replacement of the existing sewer lift station that currently serves the 141 single-family-home development to the west of the proposed project site with an upgraded system to serve both communities. The lift station would be owned and maintained by the City of Vallejo and the sanitary sewer and lift station would be designed and installed to VFWD standards. Utility installation would occur within the project footprint and there would be no impacts unique to infrastructure installation that would result in significant effects beyond those evaluated in the Initial Study.

Stormwater. Under existing conditions, the project site consists entirely of pervious surface consisting primarily of grassland. There is no existing stormwater infrastructure on the project site; however, under existing conditions, the project site drains from west to east to Benicia State Park, where stormwater runoff converges and is directed to the Carquinez Strait.140 Upon construction of the proposed project, approximately 3.95 acres (19.6 percent) of the project site would be covered by impervious surfaces and approximately 16.18 acres (80.4 percent) would be covered by pervious surfaces, consisting of landscaped areas, undeveloped open space, and bioretention areas. The proposed project would include two detention basins and approximately 7,617 square feet of bioretention space, made up of two bioretention facilities located at the northwest corner of the site and the middle east border of the site that would collect drainage from the proposed on-site stormwater infrastructure and be used for stormwater control and treatment before discharging to an 18-inch storm drain pipe that outfalls to the existing marshland area adjacent to Benicia State Park. The storm drain system would be designed and installed to VFWD standards and in compliance with the MRP. Utility installation would occur within the project footprint and there would be no impacts unique to infrastructure installation that would result in significant effects beyond those evaluated in the Initial Study.

Electricity and Natural Gas. Electricity and gas service is provided to the project site by Pacific Gas & Electric (PG&E). The proposed project would include connections to the existing gas and electric lines that run adjacent to the project site along Shady Lane and Wildflower Avenue. The proposed project would not require any new infrastructure, aside from project-specific tie-ins and lines to serve the proposed project.

Because the proposed project would connect to existing utility services adjacent to the project site and there is sufficient excess capacity within those systems to accommodate project demands, the relocation or reconstruction of new or expanded water, wastewater treatment, or stormwater drainage, electric power, or telecommunications facilities would not be required. No modifications to utility infrastructure would be necessary outside of the immediate project site footprint. As such, 140 DK Engineering. 2023. Op. cit.

4.20.1 Prior Environmental Analysis
Chapter 4.7 of the General Plan EIR analyzed impacts related to wildfire hazards associated with build out of the General Plan and determined that build out of the General Plan would result in less than significant impacts related to wildfire due to compliance with existing regulations including the California Fire Code, California Building Code, CCR, Department of Forestry and Fire Protection regulations, and the City of Vallejo Municipal Code. No mitigation measures were prescribed.

However, the General Plan includes the following policies and actions related to wildfire which would be applicable to the proposed project:
○ Policy CP-2.3: Fire Prevention and Response Services. Ensure the provision of fire prevention and emergency response services that minimize fire risks and protect life and property.
■ Action CP-2.3E: Work with property owners and public agencies to ensure that plant growth is managed to minimize fire danger.
○ Policy NBE-5.3: Health and Safety Codes. Enforce development regulations and building code requirements to protect residents, businesses, and employees from flooding, liquefaction, earthquakes, fires, and other hazards.
■ Action NBE-5.3B: Continue to require development to comply with building and safety codes and continue to route plans and drawings to all relevant City departments for review.

○ Policy MTC-2.3: Emergency Response Routes. Ensure adequate emergency vehicle access in all areas of Vallejo.
■ Action MTC-2.3B: Continue to involve the Police and Fire Departments in the development review process to ensure that applicable requirements for emergency access are met.

4.20.2 Background
The project site is within a local responsibility area (LRA), meaning the local government (the City of Vallejo) is financially responsible for wildland fire protection. However, the project site is not considered to be within a Very High Fire Hazard Severity Zone (VHFHSZ). According to the City of Vallejo General Plan 2040, the project site is within a moderate- to high-risk wildfire area.151 There are no Very High Fire Hazard Areas in or adjacent to Vallejo.

4.20.3 Impact Analysis
a. Would the project substantially impair an adopted emergency response plan or emergency evacuation plan? (Less Than Significant Impact, No New Impact) The City of Vallejo participates in a coordinated regional emergency management framework under the Solano County Emergency Operations Plan (EOP), which was most recently updated in May 2024.152 The EOP outlines emergency response procedures and assigns responsibilities consistent with California’s Standardized Emergency Management System (SEMS) and the National Incident Management System (NIMS). As part of the Solano County Operational Area, Vallejo’s emergency response and recovery efforts are integrated into countywide protocols that guide preparedness, initial response, extended response, and recovery activities. In addition, the Solano County MultiJurisdictional Hazard Mitigation Plan (2022) and the Community Wildfire Protection Plan (2023) identify local and regional risks and outline hazard mitigation and wildfire safety strategies, including those applicable to Vallejo.153, 154
At the local level, the Vallejo Fire Department leads public safety and emergency preparedness efforts, offering resources such as wildfire prevention brochures and defensible space guidance to residents. The City also participates in the Alert Solano emergency notification system, which provides timely information to residents during critical incidents such as natural disasters, 151 Vallejo, City of. 2017.

These coordinated planning efforts ensure that the City is prepared to manage and mitigate emergency situations in accordance with adopted regional and local plans.155
As previously discussed in Section 4.9, Hazards and Hazardous Materials, the proposed project would be consistent with the policies outlined in the Solano County General Plan Public Health and Safety chapter, the City of Vallejo General Plan Nature and Built Environment chapter, the Solano County EOP, and the Solano County MJHMP. The proposed project would not alter or block adjacent roadways, and implementation of the proposed project would not be expected to impair the function of nearby emergency evacuation routes. In addition, operation of the proposed project would not cause permanent alterations to vehicle circulation routes and patterns or impede public access or travel upon public rights-of-way. Prior to approval of final maps and improvement plans for any development project within Vallejo, plan review and approval by the VFD is required.

Internal roadways and ingress/egress for each site would be required to meet State and local standards regarding turning radius, road width, and emergency vehicle access.

Given that the site is located within an urbanized area and not in a designated Very High Fire Hazard Severity Zone, the proposed development would not increase wildfire risks beyond what is contemplated in the plans. Moreover, compliance with local building codes, defensible space requirements, and the City's fire prevention programs would ensure alignment with the goals of these hazard mitigation frameworks. Therefore, potential impacts to an adopted emergency response plan or emergency evacuation plan would be less than significant. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR. b. Would the project, 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? (Less Than Significant Impact, No New Impact) Construction of the proposed project would involve the use of some flammable materials, such as gasoline, diesel fuel, hydraulic oils, paints, and solvents. During construction, there would be increased human activity and ignition sources, including equipment that could create sparks, be a source of heat, or leak flammable materials on the project site. However, all construction equipment is required to have fire suppression equipment (such as a fire extinguisher) on board or at the work site, secondary containment would be required for fuel-powered equipment, and a spill kit would be required to be kept on site during construction for use in case of any leaks or spills of flammable materials. These existing requirements would reduce the potential exacerbation of wildfire risks related to construction activities.

Operation of the proposed project would be consistent with surrounding residential uses and the allowable zoning and General Plan land use designations for the project site. The proposed project would be subject to the design standards and guidelines outlined in the City of Vallejo Municipal 155 Solano County Office of Emergency Services. “Alert Solano Emergency Notification System.” Accessed May 10, 2025.

The proposed project would also be subject to requirements in Section 13000 et seq. of the California Health and Safety Code, California Building Standards Code, and California State Fire Code, which include regulations concerning the following: building standards for fire protection; fire protection and notification systems such as extinguishers and smoke alarms; safety for firefighters and emergency responders during emergency operations; minimum standards for hazardous vegetation and fuel management, defensible space, and building construction; and minimum standards for emergency access and water supply for fire response.

Compliance with these existing regulatory requirements would ensure that the proposed project would not exacerbate wildfire risks and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire. Impacts would be less than significant, and no mitigation is required. No new impacts or substantially more severe significant impacts would result with implementation of the proposed project when compared to those analyzed in the General Plan EIR.
c. Would the project 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?

The proposed project involves the construction of 51 single-family residential units. Associated improvements include utility connections to existing utility facilities, including water, sanitary sewer, storm drainage, electricity, gas, and telecommunication infrastructure. Utility connections/lines would be constructed in conformance with City standards as detailed in Section 4.19, Utilities and Service Systems. In addition, all residences would include automatic fire sprinkler systems installed in accordance with the adopted building codes. The project does not propose the installation or maintenance of any other 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, and impacts would be less than significant.

4.21.1 Impact Analysis
a. Does the project 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 with Mitigation Incorporated, No New Impact) As discussed and analyzed in this document, construction and operation of the proposed project would not substantially degrade the quality of the environment; reduce the habitat, population, or range of a plant or animal species; or eliminate important examples of California history or prehistory. The proposed project has been designed to minimize impacts to both biological and cultural resources, and implementation of project specific mitigation measures recommended in this Initial Study would ensure that impacts to biological and cultural resources are reduced to a less than significant level. Section 4.4, Biological Resources, includes mitigation measures to minimize impacts to nesting birds, roosting bats, sensitive natural communities, and wetlands. Additionally, Section 4.5, Cultural Resources, includes mitigation measures to minimize impacts to unknown cultural resources within the project site. With implementation of these mitigation measures, the proposed project would result in less than significant impacts to the quality of the environment.

Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? (Less Than Significant with Mitigation Incorporated, No New Impact)
Section 15065(a)(3) of the State CEQA Guidelines states that a project’s cumulative impacts are the possible environmental effects that may be cumulatively considerable when considered with other reasonably foreseeable projects. Cumulatively considerable impacts occur when the incremental effects of a particular project or program are significant when viewed in connection with the effects of other past, current, or reasonably foreseeable future projects. Section 15355 of the State CEQA Guidelines defines a cumulative impact as an impact that is created as a result of the combination of the project evaluated in the CEQA document together with other projects causing related impacts.

The proposed project is located in an undeveloped area, adjacent to existing residential uses. At this time, no other reasonably foreseeable projects have been identified within the immediate surroundings. While various projects within Vallejo have the potential to be under construction concurrent with the proposed project, concurrent projects within the city would be subject to regulations similar to those outlined in this document and would incorporate mitigation measures, as necessary, that would reduce impacts of the project. As shown in the discussion above, environmental impacts associated with the proposed project can be reduced to less than significant levels with the implementation of existing regulations and/or project-specific mitigation measures, with the exception of greenhouse gas emission operational impacts that would remain significant and unavoidable. All project-related impacts are localized and confined to the immediate project area. Given that the potential project-related impacts, with mitigation, would not result in any new cumulative impacts or increase the severity of a previously identified significant cumulative impact as previously analyzed, and no other CEQA standards for supplemental review are met, no new impact would occur.
c. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? (Less Than Significant with Mitigation Incorporated, No New Impact)
Based on the analysis provided throughout this Initial Study, with incorporation of mitigation measures and regulatory compliance measures, the project would not result in any environmental effects that would cause substantial adverse effects on human beings, either directly or indirectly.

Potential impacts on human beings would be less than significant with mitigation incorporated.

Therefore, implementation of the proposed project would not result in any new impacts or increase the severity of a previously identified significant impact as previously analyzed, and no other CEQA standards for supplemental review are met. No new impact would occur.
