Noise <br />Year 2013 Conditions <br />City of Santa Ana -Park View at Town and Country Manor <br />Draft EIR <br />The proposed project's potential offsite noise impacts have been calculated through a comparison of <br />the year 2013 baseline scenario to the year 2013 plus project scenario. The results of this comparison <br />are shown below in Table 4.5 -14. <br />Table 4.5.14: Year 2013 Project Traffic Noise Contributions <br />CNEL at 100 feet <br />Potential <br />No With Project Significant <br />Roadway Segment Project Project Contribution Impact? <br />Main Street <br />North of Town and <br />Country Road <br />68.3 <br />68.3 <br />0.0 <br />No <br />Main Street <br />North of Memory Lane <br />67.2 <br />67.2 <br />0.0 <br />No <br />Lawson Way <br />South of Town and <br />Country Road <br />56.6 <br />56.9 <br />0.3 <br />No <br />Parker Street <br />North of Town and <br />Country Road <br />58.9 <br />59.0 <br />0.1 <br />No <br />La Veta Avenue <br />East of Main Street <br />65.3 <br />65.3 <br />0.0 <br />No <br />La Veta Avenue <br />West of Parker Street <br />63.3 <br />63.3 <br />0.0 <br />No <br />Town and Country Road <br />East of Main Street <br />61.8 <br />61.8 <br />0.0 <br />No <br />Town and Country Road <br />West of Parker Street <br />58.1 <br />58.1 <br />0.0 <br />No <br />Memory Lane <br />East of Main Street <br />61.0 <br />61.1 <br />0.1 <br />No <br />Memory Lane <br />South of Town and <br />Country Road <br />55.6 <br />55.8 <br />0.2 <br />No <br />Source: Michael Brandman Associates, 2009. <br />Table 4.5 -14 above indicates that for the year 2013 conditions, the noise level contributions from the <br />proposed project to the study area roadways would range from 0.0 to 0.3 dBA CNEL. A 0.3 dBA <br />noise increase would occur on Lawson Way south of Town and Country Road where the baseline <br />noise level is 56.6 dBA CNEL. 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 2013 conditions. <br />Year 2030 Conditions <br />The proposed project's potential offsite noise impacts have been calculated through a comparison of <br />the year 2030 baseline scenario to the year 2030 plus project scenario. The results of this comparison <br />are shown below in Table 4.5 -15. <br />4.5 -24 Michael Brandman Associates <br />H\Clievt(PN -Rn) 327b327WMDEMVB270030 Sec0 Noi�. <br />
