AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY <br /> 12956 <br />DUDEK 71 April 2022 <br />Mitigation Measures <br />No mitigation measures are required. <br />3.13 Noise <br /> <br />Potentially <br />Significant <br />Impact <br />Less Than <br />Significant <br />Impact With <br />Mitigation <br />Incorporated <br />Less Than <br />Significant <br />Impact No Impact <br />XIII. NOISE – Would the project result in: <br />a) Generation of a substantial temporary or <br />permanent increase in ambient noise <br />levels in the vicinity of the project in <br />excess of standards established in the <br />local general plan or noise ordinance, or <br />applicable standards of other agencies? <br /> <br />b) Generation of excessive groundborne <br />vibration or groundborne noise levels? <br />c) For a project located within the vicinity <br />of a private airstrip or an airport land <br />use plan or, where such a plan has not <br />been adopted, within two miles of a <br />public airport or public use airport, <br />would the project expose people <br />residing or working in the project area to <br />excessive noise levels? <br /> <br />Setting <br />The project site is within an existing park next to urbanized areas within the City of Pleasanton. People using <br />the existing trails within the Augustin Bernal Community Park and Pleasanton Ridge Regional Park are <br />considered to be noise-sensitive receptors. Other noise-sensitive receptors near the project site are the <br />single-family residences within the Golder Eagle subdivision and the Castlewood subdivision as well as the <br />Castlewood Country Club golf course. Typical noise sources within the project vicinity include traffic on local <br />roads and noise generated at the Augustin Bernal Community Park staging area and parking lot. <br />Impact Discussion <br />a) Would the project result in generation of a substantial temporary or permanent increase in <br />ambient noise levels in the vicinity of the project in excess of standards established in the local <br />general plan or noise ordinance, or applicable standards of other agencies?
