Section 5 <br />MBI-5 Sound Wall Installation <br />The noise levels generated from the construction of the sound wall at M131-5 <br />would range from a 0.1 dB increase to a 1.2 dB increase. As shown in Table 38 <br />the construction activities would exceed the daytime time noise standard at <br />Receiver 10 by .7 dB. The construction: of the sound wall would occur during the <br />day when the construction activity would be exempt under the City's Noise <br />Ordinance. To minimize noise impacts at the Centennial Education Center, a <br />design feature has been incorporated into the project that requires the <br />construction of the MM-5 Well sound wall to occur when school is not in session. <br />Potential noise impacts would be less than significant. <br />Table 38: 1`11131-5 Sound Wall Construction Noise Levels <br />Receiver <br />Description <br />Existing <br />Existi <br />increase > <br />(1) Nolsq <br />Constructib <br />Standard <br />n <br />Thresthold <br />I <br />Multi Family west Santa <br />41.13 <br />42.1 <br />0.3 <br />55.0 <br />Ana River <br />2- <br />Multi Family west Santa <br />61.9 <br />62.0 <br />0.1 <br />64.9 <br />Ana River <br />Single Family north Edinger <br />656 <br />65.6 <br />D'O <br />686 <br />Ave. <br />4 <br />Single Family north Edinger <br />64.4 <br />64.4 <br />0.0 <br />684 <br />Ave. <br />Single Family north Edinger <br />647 <br />64.7 <br />0.0 <br />677 <br />Ave. <br />6 <br />Single family north Edinger <br />71.7 <br />71.7 <br />0.0 <br />747 <br />Ave. <br />7 <br />Single family north Edinger <br />67.6 <br />67.6 <br />0.0 <br />70.6 <br />Ave. <br />Multi Family north Edinger <br />66.2 <br />66.2 <br />0.0 <br />69.2 <br />Ave. <br />9 <br />North Centennial Education <br />59.5 <br />59,5 <br />0.0 <br />62.5 <br />Center <br />10 <br />Southeast Centennial <br />54.8 <br />55.5 <br />0.7 <br />55.0 <br />Education Center <br />-1 <br />Single Family east Fairview <br />71.8 <br />713 <br />0.0 <br />4 <br />L3 <br />Street <br />-12- <br />Single Family east Fairview <br />71.3 <br />71 <br />74 <br />Street <br />13 <br />Single Family east Fairview <br />71.3 <br />71.5 <br />0.2 <br />743 <br />Street <br />14 <br />Single Family east Fairview <br />714 <br />71.4 <br />0.0 <br />74.4 <br />Street <br />15 <br />North Go-dinez High School <br />536 <br />54.8 <br />1.2 <br />550 <br />Mid Basin Centennial Park A Project Final EIR 5-157 <br />k4z.) ce-1196 <br />
