City of Pleasanton–Spotorno Ranch Reduced Development Project Environmental Checklist Initial Study/Consistency Checklist 50 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 b) State Scenic Highways Would the project: Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway? The 1998 HVSP FEIR determined that some of the Spotorno Upper Valley Medium Density Residential area is visible from the I-680 corridor, but that the potential for adverse aesthetic impacts is minimal due to its distance from the project site. Furthermore, the 1998 HVSP FEIR determined that impacts would be less than significant with implementation of the site development standards and design guidelines, including MM L4 and MM L6. I-680, traversing Pleasanton in a north–south direction, is an officially designated State Scenic Highway. I-580 and State Route 84 (SR-84), extending west of I-680, are both Eligible State Scenic Highways but are not officially designated.14 These three highways feature wooded hillsides and valleys and other open space. The project site is 0.73 mile west of I-680; however, because of intervening hilly terrain and vegetation, the residential portion of the project is not visible from the highway. The hills surrounding Happy Valley, which include the undeveloped hillsides east of the project site are identified in the HVSP as providing a scenic resource for Valley residents and the greater community. This area would be preserved as open space as described in the Project Description, and these undeveloped hillsides would therefore maintain their scenic contribution to this scenic corridor. Furthermore, the proposed project would implement the site development standards and design guidelines required by the 1998 HVSP FEIR. As such, the proposed project would not substantially damage scenic resources, including but not limited to trees, rock outcropping, and historic buildings within a State Scenic Highway. Therefore, the proposed project would not result in any peculiar effects related to scenic resources within a State Scenic Highway and would not result in new or more severe impacts related to scenic resources within a State Scenic Highway beyond what was previously analyzed in the 1998 HVSP FEIR. c) Visual Character Would the project: In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? The 1998 HVSP FEIR determined that the Spotorno Upper Valley Medium Density Residential area would have a significant change in character as a result of the HVSP, but that the change in aesthetic character would not be one that is unusual in Pleasanton, nor would it result in a demonstrable negative effect. The MDR area analyzed in the HVSP FEIR is not part of the proposed project. The 14 California Department of Transportation (Caltrans).
