City of Pleasanton–Spotorno Ranch Reduced Development Project Initial Study/Consistency Checklist Project Description FirstCarbon Solutions 37 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx Currently there are two pedestrian facilities adjacent to the site: the Happy Valley Loop Trail and Golf Course Loop Trail. As discussed in greater detail in Section 3.12, Transportation, the proposed project would incorporate a planned trail network consistent with the intent of the network shown in the City’s 2019 Trails Master Plan and HVSP that would be approved by the City prior to the issuance of building permits. These trails are shown on Exhibit 7a. A summary of planned trails is provided below. The HVSP identifies a proposed Spotorno Flat Area Trail within the Spotorno property area. In addition, the HVSP identifies two other trails within the Spotorno property area: the “Bypass Road Trail ,” and the “Spotorno MDR/Foley Ranch Trail connection”), which would connect from the Bypass Road Trail to the east. The 1993 Trails Master Plan shows trails along Westbridge Lane, and also includes a trail connecting from approximately Minnie Street, across the north edge of the HVSP area to the east. The 1993 Master Plan shows a range of facility types and designs, ranging from “Class A” regional trails, “Class B” trails that are separated from streets, and “Class C” trails, which are local/connector trails that are typically on-street, with widths ranging from 4 to 8 feet, depending on location and use. The City’s 2019 Trails Master Plan further defines these trails to include a Class I/Multiuse trail connecting Alisal Street to Westbridge Lane, generally along the alignment of the proposed Spotorno Drive; a bicycle/pedestrian trail along the north side of Westbridge Lane then a pedestrian trail on the project site to be ultimately connected to the existing Callippe trails, and additional trails through the eastern portion of the Spotorno Ranch property, which would connect the Spotorno Flat Area Trail to the Foley property to the east, and to Lund Ranch (Exhibit 9) 2.3.5 - Grading The project proposes to balance cut and fill on-site. Approximately 29,200 cubic yards of material would be generated from grading activities to construct the home sites, streets/sidewalks, trails, and bioretention areas, and also from utility and lot spoil piles (waste material from related excavation). The majority of this material would be used as fill for the home sites; the remaining fill material would be placed on Parcels A and/or B, or would be used in the construction of on-site roads. To repair an existing landslide in the eastern portion of the Spotorno Flat Area, an additional estimated 31,000 cubic yards of cut and an equal amount of fill would be generated. The excavated material would be re-used as engineered fill, and the original grades would be restored. As a result, site grading would be balanced, and neither off-haul nor import of dirt would be required. Exhibit 10 shows the proposed grading and utility plan. 2.3.6 - Utilities The Spotorno Ranch property does not include any existing utility systems. Existing water, wastewater, and stormwater infrastructure systems are located immediately adjacent to Spotorno Ranch Drive, within Alisal Street and Westbridge Lane. Exhibit 10 shows the proposed stormwater infrastructure.
