Pimlico Drive Turnout and Pipeline Project Envirnnurentnl Ckecklist The fluoridation building will be situated in public right-of--way between Pimlico Drive and the sound wall next to Interstate Highway 580. Views of the fluoridation building will include traffic moving east and west along Pimlico Drive and partial views from the a fenced backyard of a residence located across the street from the fluoridation building. The backyard is fenced with 6-foot solid wooden slats. The fluoridation building will be designed to meet City of Pleasanton's design requirements and be similar in appearance to other fluoridation buildings throughout the City. The building will be constructed of masonry blocks compatible with the color and texture of the background sound wall. Landscaping around the fluoridation building will include shrubs installed at the entrance of the building and along the sides of the building facing Pimlico Dive to provide partial screening. A creeping vine that is similar to the existing vines on the sound wall, such as creeping fig or Boston ivy, may be planted on the side of the building facing the Pimlico Drive to provide a view of the fluoridation building consistent with the background sound wall, existing vegetation along the north side of Pimlico Drive and a view in character with the surrounding area. The radio antenna will be mounted to the fluoridation building and will be approximately 25 to 30 feet high and be about the same height as the existing 30 foot high light standards along Pimlico Drive. The mitigative design features incorporated into the project will prevent a significant impact to visual resources and will be included in the construction plans and specifications. No separate mitigation is necessary. The fluoridation building and other project features adjacent to the building will not substantially degrade the visual character of the area along the strip of land between the Interstate Highway SRO sound wall and Pimlico Drive, and impact is considered less than significant. The Santa Rita control valve vault and Zone 7 radio antenna will be located within the Santa Rita Road right-of--way between Santa Rita Road and the Rose Pavillion parking lot and to the west next to a one-story commercial building housing a delicatessen. The Santa Rita control valve vault will be below grade and not affect the visual character of the area. The impact will be less than significant. The antenna adjacent to the Santa Rita control valve vault will be about 20 to 25 feet high. The views of the antenna from the sidewalk and Santa Rita Road will be the antenna and background structures that are consistent with the commercial nature of the area including the one story commercial building and parking lot with 40-foot high light standards. Therefore, there will be no substantial impacts to the visual character of the area. The impact would be less than significant d) Less than Significant. Nighttime lighting will not be used during construction. The only lighting for the project facilities will be at the fluoridation building for security and emergency response purposes. The lighting will be low level lighting outside of the fluoridation building and will be similar to or less than the intensity of the light standards lining Pimlico Drive.
