<br /> <br />Red Morton Community Park Sports Lighting Initial Study <br />City of Redwood City 56 June 2015 <br />4.12.2 Environmental Checklist and Discussion of Impacts <br /> <br /> <br />Potentially <br />Significant <br />Impact <br />Less Than <br />Significant <br />With <br />Mitigation <br />Incorporated <br />Less Than <br />Significant <br />Impact <br />No Impact Checklist <br />Source(s) <br />Would the project result in: <br />1. Exposure of persons to or generation of noise <br />levels in excess of standards established in <br />the local general plan or noise ordinance, or <br />applicable standards of other agencies? <br /> 1,2,3,13 <br />2. Exposure of persons to, or generation of, <br />excessive groundborne vibration or <br />groundborne noise levels? <br /> 1,2,13 <br />3. A substantial permanent increase in ambient <br />noise levels in the project vicinity above <br />levels existing without the project? <br /> 1,2,13 <br />4. A substantial temporary or periodic increase <br />in ambient noise levels in the project vicinity <br />above levels existing without the project? <br /> 1,2,13 <br />5. For a project located within an airport land <br />use plan or, where such a plan has not been <br />adopted, within two miles of a public airport <br />or public use airport, will the project expose <br />people residing or working in the project area <br />to excessive noise levels? <br /> 1,2 <br />6. For a project within the vicinity of a private <br />airstrip, will the project expose people <br />residing or working in the project area to <br />excessive noise levels? <br /> 1,2 <br /> <br />4.12.2.1 Noise Effects <br /> <br />Sports Activities <br /> <br />As described previously, the existing noise environment is dominated by traffic noise from the <br />surrounding residential streets. In addition to the local traffic noise, Red Morton Community Park <br />currently has baseball, softball, and soccer games and practices, as well as other recreational <br />activities at the picnic areas, playground facilities, and tennis courts, which would generate sporadic <br />noise. Under the conditions of the proposed project, the existing sports lighting surrounding the <br />Bechet/Griffin Field and the tennis courts, located in the southern portion of the Red Morton <br />Community Park, would be replaced with new sports lighting. The new sports lighting fixtures would <br />not alter the noise environment, seeing as the nature of the activities and the hours of operation <br />would not change with the proposed project. The noise environment in the southern portion of the <br />park would remain approximately 60 dBA CNEL under future conditions, which meets the noise <br />threshold for recreational areas. <br /> <br />8.A. - Page 73
