Pimlico Drive Turnout and Pipeline Project Environnrentrrl C/:ecklist f) For a project within the vicinity of a private ~ ~ ~ ~X airstrip, would the project expose people residing or working in the project area to excessive noise levels? lliscussion a, b, d) Less than Significant. Construction of the project facilities would involve use of construction equipment, such as, a backhoe, excavator, loader, dump truck, small flatbed mounted crane, saw cutter, flat bed trucks, hand compaction equipment, dump truck, bulldozer, small compressors and generation of construction traffic, resulting in a temporary short terns increase of noise due to construction activities. These types of equipment normally do not produce strong impacts to the ground that would result in noticeable ground vibration. The increase in ground vibration will be relatively minor and of short duration. Project construction has the potential to expose people adjacent to construction work area to objectionable sound if loud construction occurs during sensitive hours in the residential and commercial areas adjacent to the construction area. The following Project Measure will be implemented to avoid exposing the public to increased noise levels during sensitive hours of the day and ensure that increased noise levels during construction do not exceed the City's noise ordinance requirements. Therefore, this would be less than significant with implementation of Project Measure NOISE-I : Construction Noise. c) Less than Significant. Operations of the pipeline and project facilities will not exceed noise levels set forth in City of Pleasanton's Noise Regulations. The project facilities are not noisy. "fhe pipeline will be underground, which will attenuate any noise created by water flow. The fluoridation building will be constructed of masonry block, which will attenuate any noise from the equipment housed in the building. Noise from equipment housed in the Zone 7 htrnout, City of Pleasanton vault or Santa Rita control valve vault will be attenuated by the enclosures and ground. Therefore, this would be less than significant. e, f) No Impact. "The proposed project is not located in an area addressed in the Livermore Airport Master Plan (City of Livermore 2004) nor is it near a private airstrip. Therefore, e and f would be no impact.
