City of Santa Ana -Park View at Town and Country Manor <br />Draft EIR <br />Noise <br />Table 4.5.15: Year 2030 Project Traffic Noise Contributions <br />CNEL at 100 feet <br />Table 4.5 -15 above indicates that for the year 2030 conditions, the noise level contributions from the <br />proposed project to the study area roadways would range from 0.0 to 0.1 dBA CNEL. A 0.1 dBA <br />noise increase would occur on Lawson Way south of Town and Country Road, and both analyzed <br />segments of Memory Lane. None of the roadway segments would exceed the thresholds of <br />significance discussed above. Therefore, based on thresholds of significance defined above, no <br />significant offsite noise impacts from project - related vehicle noise would occur along the study area <br />roadways segments for the year 2030 conditions. <br />Level of Significance Before Mitigation <br />Less than significant. <br />Mitigation Measures <br />No mitigation measures required. <br />Level of Significance After Mitigation <br />Less than significant. <br />Michael Brandman Associates 4.5 -25 <br />H\Cl t(PN- JN)b327b32]003MMVB2]0030 Sec0 Noi�.doc <br />Potential <br />No With <br />Project Significant <br />Roadway Segment Project Project <br />-on Impact? <br />Monrovia Avenue <br />North of 16th Street <br />55.8 <br />55.9 <br />0.1 <br />No <br />North of Town and <br />Main Street <br />Country Road <br />67.7 <br />67.7 <br />0.0 <br />No <br />Main Street <br />North of Memory Lane <br />67.9 <br />67.9 <br />0.0 <br />No <br />South of Town and <br />Lawson Way <br />Country Road <br />60.5 <br />60.6 <br />0.1 <br />No <br />North of Town and <br />Parker Street <br />Country Road <br />62.4 <br />62.4 <br />0.0 <br />No <br />La Veta Avenue <br />East of Main Street <br />64.5 <br />64.5 <br />0.0 <br />No <br />La Veta Avenue <br />West of Parker Street <br />64.7 <br />64.7 <br />0.0 <br />No <br />Town and Country Road <br />East of Main Street <br />62.0 <br />62.0 <br />0.0 <br />No <br />Town and Country Road <br />West of Parker Street <br />61.5 <br />61.5 <br />0.0 <br />No <br />Memory Lane <br />East of Main Street <br />61.3 <br />61.4 <br />0.1 <br />No <br />South of Town and <br />Memory Lane <br />Country Road <br />59.4 <br />59.5 <br />0.1 <br />No <br />Source: Michael Brundman Associates, 2009. <br />Table 4.5 -15 above indicates that for the year 2030 conditions, the noise level contributions from the <br />proposed project to the study area roadways would range from 0.0 to 0.1 dBA CNEL.
