The locations of the proposed noise barriers are shown on Figure 3-8. The noise barriers would need to be constructed of a material with a minimum surface weight of four pounds per square foot and have no visible cracks or gaps, especially at the base. The applicant has agreed to these mitigation measures provided that suitable access for fire control can be maintained at F Street. With the inclusion of these mitigation measures, CSAI indicates that noise generated by the project can be reduced to the rfollowing levels: Nearest Residential Properties Daytime Le 48 dBA Y q Nighttime Leq 44 dBA Lmax 65 dBA Nearest Commercial Properties Daytime Leq q 53 dBA Nighttime Leq 49 dBA Lmax 73 dBA The project levels, with mitigation, are below the applicable City standards. Therefore, with the inclusion of the following mitigation measures, the proposed use of the project site would not result in significant noise impacts. Level of Significance: Significant Mitigation Measures: 1. The proposed project shall construct minimum 8-foot noise barriers at the r locations shown on Figure 3-8 prior to proposed operations. The noise barriers shall be constructed of a material with a minimum surface weight of four pounds per square foot and have no visible cracks or gaps, especially at the base. Significance After Mitigation: Less than significant rImplementation: The ODS will be responsible for design and construction of noise barriers. rMonitoring: The Community Development Department will be responsible for ensuring that noise barriers have been constructed as required prior to project operation. 1 121339/ST011 R226 3-50 October 14, 2011 Copyright 2011 Kleinfelder
