KLE/NFEL®ER Bright People.Fight Solutiom b. Off-Site Transportation Sources. Off-site transportation sources would include truck and other vehicle traffic generated by the project as it occurs on public streets, including Weber Avenue adjacent to the site. Noise from these sources was analyzed with respect to standards for"transportation-related sources." The proposed project would involve a beneficial noise effect at the existing Lincoln Street site. The project would eliminate all existing trucking and waste processing activity at this location, reducing existing noise levels for land uses in the vicinity. tImpacts of On-Site (Land Use-Generated) Operations on Noise-Sensitive Land Uses in the Project Vicinity The CSAI study quantified noise that would be generated from the expanded recycling facility and calculated project-generated noise levels that would be experienced at residential commercial and industrial land uses in the project vicinity. This analysis is summarized in Table 6 below: TABLE 3-6 PROJECT NOISE LEVELS AT NEAREST LAND USES Land Use Descriptor Predicted Noise Applicable Noise Exceedence Level (dB) Standard (dB) Residential Leq Day 55 55 No Leq Night 52 45 Yes Lmax Day 74 65 Yes Lmax Night 74 65 Yes Commercial Leg 58 65 No Lmax 78 75 Yes Industrial Leg <70 70 No Lmax <80 80 No The CSAI analysis indicates that noise generated from within the proposed project site would exceed City Development Code noise standards for residential and commercial land uses in the project vicinity. This is a significant noise effect, and feasible mitigation measures must be identified. CSAI identified mitigation measures that would result in acceptable noise levels at nearby residential uses. Mitigation measures would consist of 8-foot tall perimeter barriers along a portion of the ESRTS site as well as an 8-foot barrier along the west 121339/ST011 R226 3-49 October 14, 2011 Copyright 2011 Kleinfelder
