buildings would so strongly influence the noise attenuation rate that <br /> accurate modeling would be nearly impossible. However, one could <br /> anticipate that traffic noise within the project's interior would be <br /> reduced from 5 to perhaps, 15 dB lower than roadside depending on the <br /> location. <br /> The reader will notice that the results from the computer model on <br /> page 48 are in dBA, Leq; whereas, the noise descriptor used in the <br /> City's noise element is CNEL. The difference lies in how each <br /> descriptor is defined. Suffice to say that for traffic distribution <br /> typical of a residential area, the difference between the Leq and the <br /> CNEL noise descriptors would be within 1/2 dBA and may be ignored for <br /> the purpose of traffic noise prediction. <br /> Based upon the results from the computer model , it does not appear <br /> likely that any of the project's buildings would require special <br /> acoustic studies or architectural features to reduce noise transmission. <br /> It may be possible that with the project and full build-out of census <br /> tracts 24 and 25, residences constructed close to the intersection of <br /> Fresno Avenue and Eighth Street and north of the project may be exposed <br /> to noise levels of 60 or greater dBA, CNEL. <br /> MITIGATION: <br /> No noise mitigation other than standard building construction is <br /> necessary for the project at this time. <br /> 47 <br />
