Section 5 <br />With the construction of the sound walls, the well construction activities would <br />result in noise levels that would range from a 0.1 dB increase to a 4.2 dB <br />increase. As shown in Table 48, the well construction activity would not exceed <br />the daytime noise standard. Additionally, the well construction activities would be <br />conducted during the day when the construction activity would be exempt under <br />the City's Ordinance. Potential noise impacts would be less than significant. <br />Table 49: MBI-3 Well Construction Night Time Noise Levels <br />Receiver <br />School <br />Existing i <br />Existing* <br />lo&ease <br />Tbreshold <br />17 <br />North Heritage Museum <br />48.1 <br />- <br />48.4 <br />0 3 <br />55.0 <br />1 <br />Structure <br />346 <br />444 <br />7 <br />9.8 <br />50.0 <br />18 <br />South Godinez High <br />43.3 <br />43.3 <br />01 <br />55,0 <br />2 <br />School <br />545 <br />54.6 <br />01 <br />57.5 <br />19 <br />Northwest Godinez <br />462 <br />48.4 <br />-7 <br />2.2 <br />5-0 <br />3 <br />High School <br />58.1 <br />58.2 <br />0.1 <br />61.1 <br />I -City Noise.
