City of Pleasanton–Spotorno Ranch Reduced Development Project Project Description Initial Study/Addendum 24 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx developed as a component of the PUD.8 Each home would provide an ADU of up to 1,000 square feet, whether attached to the main house or freestanding. ADUs, per the Pleasanton Municipal Code (PMC), would be built within the maximum floor area ratio (FAR) for the PUD (25 percent for 2- stories and 40 percent for single-story) and could also be built as second story units. Although maximum height of an ADU is limited by the City’s code to 16 feet, a PUD is allowed to propose up to 25 feet in the proposed design guidelines.9 The proposed project would require the development of an internal circulation system connecting the project to Alisal Street on the west and Westbridge Lane on the south (including new trails), roadway improvements, landscaping, and bioretention facilities. In accordance with the requirements of the HVSP, the proposed project would permanently preserve approximately 81 acres of Lot 98 (labeled as “Parcel C” on the proposed site plan in Exhibit 3) as agricultural open space.
