The application proposes to subdivide a 100 acre parcel to create 20 single family lots. The site is located at the terminus of Borica Drive and Como Way (APN: 217-010-018 thru 012). BACKGROUND/DESCRIPTION The Town is in the early stages of reviewing an application by Bates Stringer Martin Hills Ranch, LLC requesting approval of a Planned Unit Development – Rezoning , Major Subdivision, and Development Plan application. The Planned Unit Development - Rezoning request would rezone the 100 acre site from A-4; Agricultural Preserve District to P-1; Planned Unit Development District. The Major Subdivision would allow the site to be subdivided into 20 single family lots and to develop the lots with 20 single family residences. The lots would be clustered onto a small portion of the site and the remainder of the site would be designated as permanent open space. During the Town’s early discussions with the applicant regarding this application, it was determined that an Environmental Impact Report (EIR) should be required to be prepared to study potentially significant environmental impacts which may be associated with development of the project. Once prepared, the Draft EIR will be made available for public review and comment. A Response to Comments – Final EIR will then be prepared. The Town of Danville will be the Lead Agency for preparation of the EIR. The California Environmental Quality Act (CEQA), Section 15082, states that once a decision is made to prepare an EIR, the Lead Agency must prepare a Notice of Preparation (NOP) to inform all responsible agencies and the public of that decision. The purpose of the NOP is to provide responsible agencies and interested parties with sufficient information describing the proposed project and its potential environmental effects to enable them to make a meaningful response as to the scope and content of the information to be included in the EIR. The purpose of this public scoping session is to allow for oral comments from the public and from the Planning Commission regarding the scope of the EIR. The NOP was also sent to the California State Clearinghouse for distribution to interested/responsible State agencies and was sent to local agencies, districts, and interested parties. Both written and oral comments are treated equally by the Town for PUD24-0002 Scoping Session 2 January 28, 2025 the purpose of determining the scope of the EIR. The comment period for the NOP is 30 days, extending from January 21, 2025, through February 20, 2025 ENVIRONMENTAL REVIEW A Draft Environmental Impact Report (EIR) will be prepared to analyze any potential environmental impacts and associated mitigation measures. During the 30-day Notice of Preparation (NOP) public review period, people are encouraged to provide comments regarding the scope and content of the Draft EIR, a document which addresses potential environmental issues and proposed mitigation measures. PUBLIC CONTACT Public notice of the January 28, 2025, hearing was mailed to property owners within 750 feet and posted online. A total of 204 notices were mailed to surrounding property owners. RECOMMENDATION Conduct a Public Scoping Session to provide input and allow public testimony related to the preparation of an Environmental Impact Report for a P-1; Planned Unit Development – Rezoning (PUD 24-0002), Major Subdivision (SD 9679), and Development Plan (DEV24- 0010) application.

The Town is bordered to the north by the unincorporated community of Alamo, to the east by the unincorporated communities of Blackhawk and Diablo, to the south by the City of San Ramon, and to the west by the Las Trampas Regional Wilderness Park and unincorporated Contra Costa County (Exhibit 1). Located in southwestern Contra Costa County, the Town covers approximately 18 square miles and has historically been a suburban community serving major employment centers to the west (e.g., the City of San Francisco) and to the south (e.g., the City of San José). Regional access to the Town is provided by Interstate 680 (I-680) and State Route (SR) 24 to the west and I-580 to the south. Local Setting The approximately 102-acre project site is located off Borica Drive and Como Way; however, development under the proposed project would only occur within 29 acres in the southeastern portion of the site (Exhibit 2). The project site does not currently have a street address but can be accessed at the eastern ends of Borica Drive and Como Way. The project site consists of five Assessor’s Parcel Numbers (APNs): 218-010-008, 218-010-009, 218-010-010, 218-010-011, and 218- 010-012. Presently, the project site is vacant and varies topographically. The northeastern and western portions of the project site are steep and hilly with a relatively flat plateau at the highest point of the project site. The northern and eastern portions of the project site contain some small ravines and natural drainage features following the natural drainage downward. Overall, the project site has a total elevation gain of approximately 165 feet from the lowest portion of the project site in the southeast, which is approximately 590 feet above mean sea level (AMSL) to the highest point of the project site, approximately 754 feet AMSL. The project site is located within the Diablo, California United States Geological Survey (USGS) 7.5- minute Topographic Quadrangle Map (Latitude 37° 47' 54.15" North; Longitude 121° 57' 30.94" West). 12 29 37 4 4 C o n t r a C o s t a C o u n t y A l a m e d a C o u n t y 580 92 24 680 780 160 CarquinezStrait 80 80 Mount DiabloState Park Napa County Solano County 580 80 Solano C o u n t y Vallejo Richmond San Pablo Pinole Martinez Pleasant Hill LafayetteOrinda El Cerrito Albany Berkeley MoragaPiedmont Oakland Alameda Walnut Creek Concord Clayton Pittsburg Benicia Denverton Cordelia Alamo Danville San Ramon Dublin Pleasanton LivermoreFairview Hayward San Leandro Antioch Bay Point 242 680 680 13580 880 Oakland International Airport N a p a R i v e r Exh ibit 1Region al Location Map 5 0 52.5 Miles Text Project Site Source: Cen sus 2000 Data, Th e Californ ia Sp atial In formation Library (CaSIL).

In 1997, the Williamson Act Contracts that applied to the project site expired and were not renewed. However, the expiration of the Williamson Act Contracts were not propery recorded; therefore, when the current General Plan was adopted, the properties under this land use designation were incorrectly identified as bound by Williamson Act Contracts to remain in agricultural use. The Town officially filed the expiration of the Williamson Act Contract on August 21, 2024. While the property is still zoned A-4, because the project site’s Williamson Act Contract has expired, the site is entitled to return to the A-2, General Agricultural Zoning District, which applied prior to the Willamson Act Contract. The A-2 district permits all types of agriculture, including farming, horticultural, and livestock production, other agricultural uses, such as sheds, warehouse, and granaries, and a detached single-family dwelling and accessory structures on each parcel. The A-2 district allows residential uses at a density of one unit per 5 acres. Surrounding Land Uses The project site is surrounded by the following land uses: North The General Plan designates the vacant land immediately north of the project site as Residential, Single-family–Rural Residential (Rural Residential), as well as General Open Space, and the existing single-family homes north of the project site as Residential, Single-family–Country Estate (Country Estate), and Residential, Single-family–Low Density (SFL). South The General Plan designates the vacant lands south of the project site as General Open Space and the existing single-family homes farther south of the project site as Residential, Single-family– Medium Density (SFM). East The General Plan designates the vacant lands east of the project site as Rural Residential and General Open Space. Wes t The General Plan designates the existing single-family homes west of the project site as SFL and SFM. Project Description Proposed Residential Project The project applicant proposes to construct 20 single-family homes, with approximately 25 percent (five homes) being designed with accessory dwelling units (ADUs) (Exhibit 3). The residential lots Town of Danville—Martin Hills Ranch Residential Project Notice of Preparation FirstCarbon Solutions 7 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/5960/59600001/NOP/59600001 Danville Martin Hills Ranch NOP.docx would be clustered in the southeastern portion of the approximately 102-acre project site. The proposed project is expected to generate approximately 70 residents.1,2 The 20 residential lots would range between 14,553 square feet and 25,387 square feet and the proposed project would also include several agricultural lots located north and west of the residences. Furthermore, the proposed project would construct project access off Como Way and internal streets to provide internal circulation within the project site. Land Use Designation and Proposed Zoning The proposed project includes the development of 20 residential lots and 5 ADUs. The site’s General Plan land use designation is Open Space–Agricultural. The Town’s A-2; General Agricultural District is listed as Consistent with this land use designation. As previously discussed, the project site’s Williamson Act Contract was not renewed; therefore, its underlying zoning district would apply to the proposed project. The applicable A-2 District permits one dwelling unit per 5 acres. Given that the project site is approximately 102 acres, the existing zoning for the project site would allow up to 20 residential lots. However, because the project applicant proposes to cluster the residential lots in the southeast corner of the project site, the proposed project would require a rezone to Planned Unit Development District (P-1). The Town’s 2030 General Plan includes the subject “Elworthy East/Bolero” site as a Special Concern Area, and provides additional direction to guide development of the site. Language within the Special Concern Area acknowledges the limited development potential of the site, and requires that that steeper slopes and ridgeline areas be preseved as permanent open space. Site Access, Circulation, and Parking Vehicle The project site would be accessed via a proposed private extension of Como Way at the southwestern corner of the project site that would serve all of the proposed lots within the proposed project. There would be one cul-de-sac off the proposed Como Way extension that would serve Lots 13, 14, 15, and 16 (Court A). The proposed Como Way extension would terminate at the northeastern corner of the residential development area near Lots 9, 10, 11, and 12. In addition to the two- to three-car garages attached to each proposed single-family home and the parking available within the driveway, the proposed project would also provide 10 parking spaces on internal streets. Specifically, two on-street parking stalls would be provided in front of Lot 18, two on-street parking stalls would be provided in front of Lot 16, four on-street parking stalls would be provided in front of Lots 12 and 13, and two on-street parking stalls in front of Lot 8. 1 Project population calculated by multiplying the total number of dwelling units (19 single-family homes and five ADUs) by the Town’s average household size of 2.75 persons (24 x 2.75 = 66). 2 United States Census Bureau. 2024.

Storm drains would range from approximately 12 inches to 24 inches within the project site. The proposed project would include two drainage management areas (DMAs), including two bioretention areas, as stormwater treatment features: • DMA 1: DMA 1 would include the residential lots and the majority of the internal roadways, totaling approximately 10.56 acres. DMA 1 would include one bioretention area (Bioretention Area 1) located along the north side of the proposed extension of Como Way, directly west of Lot 1, totaling approximately 10,560 square feet. DMA 1 would be routed to a new outfall in the eastern channel of the project site. • DMA 2: DMA 2 would include an approximately 2.80-acre area just west of the existing terminus of Como Way. It would contain one approximately 1,140-square-foot bioretention area (Bioretention Area 2) located just south of the proposed Como Way extension at the entrance of the proposed development. DMA 2 would drain to an existing storm drain within Como Way. Additionally, the proposed project would also construct a debris berm and V-ditch in the western boundary adjacent to existing homes. Sanitary Sewer Sanitary sewer service for the proposed project would be provided by Central Contra Costa Sanitary District (Central San). Sanitary sewer service to the project site would be provided by a connection to proposed off-site 8-inch diameter sewer lines in the southwest corner of the project site.

Potential Environmental Effects The Draft EIR will evaluate if there are potentially significant environmental impacts associated with approval and implementation of the proposed project. Consistent with the CEQA Guidelines (Appendix G), the Draft EIR will analyze the reasonably foreseeable direct, indirect, and cumulative effects of the proposed project on focused resources, including, but not limited to: • Aesthetics, Light, and Glare • Hydrology and Water Quality • Agricultural and Forestry Resources • Land Use and Planning • Air Quality • Noise • Biological Resources • Public Services • Cultural Resources and Tribal Cultural Resources • Recreation • Energy • Transportation • Geology, Soils, and Seismicity • Utilities and Service Systems • Greenhouse Gas Emissions • Wildfire • Hazards and Hazardous Materials Potentially Significant Environmental Issues In preparation of the NOP and the Project Description, the Town has found that the following topical areas may contain potentially significant environmental issues that will require further analysis in the Draft EIR. These topical areas are as follows: • Biological Resources–The proposed project site contains an environment with ephemeral drainages and seasonal wetlands, which are protected by State and federal laws. Impacts to these aquatic features could be potentially significant unless fully mitigated through the implementation of mitigation measures or design features. • Geology, Soils, and Seismicity–The proposed project site contains a documented history of landslides and differing elevations and slopes. Impacts related to geology and soils could be potentially significant unless fully mitigated through the implementation of mitigation measures or design features. • Transportation–The proposed project includes the extension of Como Way to serve the proposed homes in addition to the existing homes along Como Way. Impacts related to traffic could be potentially significant unless fully mitigated through the implementation of mitigation measures of design features.

Additionally, there are no known locally important mineral resources within the Town. As such, the proposed project would have no impact related to mineral resources. •Population and Housing–The proposed project would include 20 single-family homes and five deed-restricted ADUs. As such, the proposed project would be expected to generate approximately 70 residents. The current population of the Town is approximately 44,000 persons. The General Plan EIR projected an increase up to approximately 50,760 persons in the year 2030. As such, the increase of approximately 70 persons estimated under the proposed project would be well within the projected population increase of the General Plan EIR as the current population of the Town is approximately 42,299 persons. Therefore, the proposed project would not result in unplanned population growth. Additionally, the project site is currently vacant, containing no residential structures. Therefore, the proposed project would not displace existing persons or housing, and there would be no impacts related to displacement of persons or housing.
