City of Pleasanton–Spotorno Ranch Reduced Development Project Initial Study/Consistency Checklist Environmental Checklist FirstCarbon Solutions 51 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx 1998 HVSP FEIR concluded that impacts would be less than significant with implementation of the site development standards and design guidelines, including MM L4 and MM L6. Visual simulations were included in a 2018 Draft SEIR to show the potential visual and aesthetic impacts of constructing 39 proposed residential units on the same project site. They are included as an example here. The visual simulations show the impacts at full buildout compared to the existing conditions, from several viewpoints to demonstrate the project’s potential impacts to foreground, middle ground, and background views. Exhibit 11a depicts the viewpoint locations and the direction depicted in the visual simulations. The project site plan shown in the exhibit is the previously proposed 39-unit development, not the currently proposed 22 units with 22 ADUs. As shown in Exhibit 11b through Exhibit 11g, buildout of the proposed project would maintain all background views of hillsides and Pleasanton Ridgelands while also fulfilling General Plan and HVSP goals and policies. As shown in the visual simulations, background views and views of the mountains and hillsides would not be impacted by the project; in general, some middle-ground views of the site would be changed by project development, and some foreground views would also be altered. Furthermore, since the visual simulations showed buildout of 39 residential units and the proposed project would only include 22 residential units with 22 ADUs, visual impacts of the currently proposed project would be reduced from what is depicted. Therefore, the proposed project would not have a substantial impact on public views of hillsides and mountains and would comply with HVSP goals and policies to retain views of background hillsides and mountains. The land surrounding the project site consists of rural residential development to the west, southwest, and north; open space to the northeast, and east; and a golf course to the south along with residential properties surrounding the golf course. The homes surrounding the project site are large lot single-family homes with mature landscaping, large trees, and some agricultural uses such as horse stables. The project proposes 1- and 2-story homes with ADUs, consistent with the HVSP and PUD design guidelines; the maximum height of the single-family homes would be established at 30 feet. The proposed project would incorporate landscaping that would be consistent with the existing neighborhood and streetscape of the project area. The design guidelines applicable to the project site, as provided in the HVSP, are intended to maintain a positive visual character for new development. Adherence to the design guidelines as set forth in the HVSP would ensure the new development would blend in with the surrounding areas and maintain a low visual profile relative to the surrounding hills. Although new buildings would be noticeable from areas that surround the project site, the proposed new buildings would be consistent with the character of the site and existing development in the surrounding areas to the west and south of the project site and would not change the visual character of the site beyond what was analyzed in the 1998 HVSP FEIR. Therefore, the proposed project would not result in any peculiar effects related to the visual character or public views of the site and would not result in new or more severe impacts related to visual character or public views of the site beyond what was previously analyzed in the 1998 HVSP FEIR.
