City of Pleasanton–Spotorno Ranch Reduced Development Project Initial Study/Consistency Checklist Environmental Checklist FirstCarbon Solutions 49 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx possible. With implementation of these site development standards and design guidelines, impacts were determined to be less than significant. As shown in Exhibit 5, the project site is located within the Greater Happy Valley Subarea and the Agriculture/Open Space Subarea. The Pleasanton General Plan recognizes arroyos, ridge views, hillsides woodlands, valleys, grazing lands, major city entryways, and open space areas as scenic resources. Scenic resources visible from the project site include hillsides, ridgelines, and open spaces. To the north, scenic resources include background views of the Blackhawk Hills, part of the Diablo Range, and Mount Diablo. To the east, scenic resources include open spaces. To the west, scenic resources include background views of wooded hillsides and ridgelines. These scenic resources are primarily part of background views seen at a distance. Development and land use activities may result in buildings and structures that could interrupt scenic vistas from within and adjacent to the project site. However, such interruptions would be intermittent, and the visible hillside portions would be maintained as open space. Furthermore, in contra st to the development proposed as part of the 1998 HVSP, the currently proposed project would not result in any development of the Spotorno Upper Valley Medium Density Residential area; all development would occur within the Spotorno Flat Area, and would not therefore result in hillside development that could result in potential loss of vistas of open hillsides. Consistent with the HVSP, the area designated for Agriculture/Open Space would not be developed, and measures would be implemented to minimize the visibility of development to the fullest extent possible, consistent with the required site development standards and design guidelines. The proposed project would also be in compliance with other City measures designed to protect scenic resources and scenic vistas, such as Measures PP, and QQ, which limits development in hillside areas, and Measure FF and the General Plan Land Use Element Policy 22, which limits urban development outside of the UGB line. Development and land use activities would also be required to adhere to the HVSP design guidelines, including an overall building height limitation of 30 feet for 2-story homes, 24 feet for 1-story homes, and 25 feet for an ADU. Six of the lots would be restricted to 1-story houses. The locations of these six houses would be specified in the design guidelines in order to satisfy the Specific Plan requirement for view corridor protection. Because the proposed ADUs would be built at the same time as each single- family house, the design of each will be considered concurrently for conformance with the design guidelines. The addition of an ADU to a single-family lot cannot exceed the FAR for that lot. This would ensure that buildings are consistent with existing urban development in Pleasanton and minimize the interruption of background views of scenic resources. Design features for development of all uses would complement the adjacent properties and draw on their surroundings to ensure compatibility and consistency with the character and quality of other residential properties in Happy Valley. Special emphasis would be placed on setbacks; building height, massing and scale; landscape treatments; architectural design; and color palettes to ensure compatibility. Furthermore, the substantial portions of the site that would be maintained as agricultural open space would continue to provide visual corridors to surrounding scenic vistas. Therefore, the proposed project would not result in any peculiar effects related to scenic vistas and would not result in new or more severe impacts related to a scenic vista beyond what was previously analyzed in the 1998 HVSP FEIR.
