City of Pleasanton—Stoneridge Mall Residential Project CEQA Checklist Section 15183 Checklist/15164 Addendum 48 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480017/Consistency Checklist/21480017 Stoneridge Mall Residential Project Checklist Addendum_Updated.docx Environmental Setting The project site is relatively flat and consists entirely of a paved parking lot with intermittent trees of various types and heights, including Heritage Trees as discussed in Section IV, Biological Resources, located throughout and along the project boundary. The project site is situated in an area dominated primarily by multi-story commercial buildings and related parking lots, although some smaller-scale residential buildings are located in the vicinity. The Stoneridge Mall is located to the north (parking structure and former Sears building) and west (various stores and Macy’s). Stoneridge Mall Road is located directly east and south of the project site. The Stoneridge Mall building ranges from one to three stories and contains a variety of storefronts and parking facilities. Further to the east are two, 5-story commercial office buildings and related parking areas. To the south is a newly constructed commercial office building. The Stoneridge Apartments, a complex of 3-story residential buildings and parking, are located to the southeast. The top of the Pleasanton Ridge to the west can be seen intermittently from the project site, particularly in the eastern portion. Buildings and trees otherwise generally obscure such views of the Ridge. In the vicinity of the project site, such as Stoneridge Mall Road (east), Genomics Place, and Embarcadero Court, trees and buildings obstruct nearly all views of the Ridge. The project site is located approximately 0.25 mile west of Interstate 680 (I-680), which is designated as a State Scenic Highway. The proposed project is located approximately 0.33 mile south of I-580, which is an Eligible State Scenic Highway, but is not an officially designated scenic route. Findings a) Scenic Vistas Prior EIR Conclusions The Prior EIR concluded that implementation of the Housing Element, applicable General Plan, applicable zoning requirements, and design guidelines and specific plans would protect Pleasanton’s visual resources—including hillsides and ridgelines—from impacts resulting from development consistent with the Housing Element, with the exception of Site 7. Mitigation Measure (MM) 4.A-1 was identified to reduce impacts related to the development of Site 7. Impacts were determined to be less than significant with mitigation incorporated. MM 4.A-1 is specific to Site 7 and does not apply to Site 3, the project site. Analysis of Proposed Project Scenic resources include Mount Diablo to the north, the Pleasanton Ridge west of I-680, and hills to the west, southeast, and east. Views of these resources as seen from the project site are mostly obstructed by mature trees and by surrounding urban development. At areas adjacent to the project site, such as Stoneridge Mall Road (east), Genomics Place, and Embarcadero Court, trees and buildings obstruct nearly all views of the Ridge. Therefore, the proposed project would not substantially alter these views and thus would not introduce any new impacts to scenic vistas.
