DISCUSSION: There are no known mineral resources at or near the project site, according to the San Leandro General Plan (City of San Leandro, 2002). XI. NOISE -- Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of excessive ground borne vibration or ground borne noise levels? c) A substantial pennanent increase in ambient noise levels in the project vicinity above levels existing without the project? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project ~ea to excessive noise levels? DISCUSSION: Potentially Significant Impact Potentially Significant unless Mitigation Incorporated Less than Significant Impact No Impact o ~ ~ o o ~ There are currently no sensitive receptors (e.g., schools, hospitals, or significant groups of residences) in the area within 1,000 feet (304.8 meters) of the project site. The nearest individuals who could be affected by construction noise from the project would be users of the undeveloped Oyster Bay Regional Shoreline park and workers at the City's wastewater treatment plant or at the adjacent industrial businesses along Davis Street or Neptune Drive. The nearest collection of single family residences is approximately 3,000 feet (914.4) south of the project site in the neighborhood adjacent to the San Leandro Marina o o ~ Construction of the bicycle/pedestrian trail and bridge would involve the use of diesel-powered heavy equipment for limited excavation, delivery of materials, driving of bridge piers and placement of bridge truss sections with a crane, cement mixing, backfilling of excavated areas, and paving of the trail. Based on U.S. EPA data on typical noise ranges generated by earth moving equipment (excavators, backhoes, and trucks), such equipment could generate temporary noise levels of about Y4204IS.00693.doc - 4/5/07 o o o o o o o ~ o o o ~ o o o -32-
