Section 5 <br />With the construction of the sound walls, the devellopment of the monitoring well <br />would result in noise levels that would range from a 0.2 dB increase to a 4.9 dB <br />increase. As shown in Table 71, the development of the monitoring well would <br />not exceed the night time noise standard. Potential noise impacts would be less <br />than significant. <br />.. 0 <br />The noise levels generated from well equipping at MBI-2 and MBI-4 are shown in <br />Table 72. All of the well equipping activities Would occur during the day over a <br />14 day period. <br />Table 72: M131-2 and Ill Well Equipping Noise Levels <br />Receiver <br />EdUCatiOn Center <br />Existing <br />ExIlstirip + <br />Increase <br />Threshold <br />11 <br />Single Family east <br />66,7 <br />66.7 <br />D'a <br />69.7 <br />1 <br />Fairview Street <br />41.8 <br />43.2 <br />1.4 <br />55.0 <br />12 <br />Single Family east <br />66.3 <br />66.3 <br />00 <br />69.3 <br />2 <br />Fairview Street <br />61.9 <br />62.0 <br />0.1 <br />64.9 <br />13 <br />Single Family east <br />66.3 <br />663 <br />0,0 <br />69.3 <br />3 <br />Fairview Street <br />65.6 <br />65.6 <br />0.0 <br />68.6 <br />14 <br />Single Family east <br />66.3 <br />66.3 <br />0.0 <br />69.3 <br />4 <br />Fairview Street <br />64.4 <br />64.4 <br />OL <br />67.6 <br />15 <br />North Godinez High <br />48.4 <br />484 <br />0.0 <br />500 <br />5 <br />School <br />64.7 <br />64.8 <br />73 <br />16 <br />Northwest Mitchell <br />37.4 <br />39.1 <br />1.7 <br />500 <br />School <br />17 <br />North Heritage <br />42.9 <br />44.3 <br />1.4 <br />50.0 <br />MUSeUrn Structure <br />18 <br />South Godinez High <br />38.2 <br />43.1 <br />4.9 <br />50.0 <br />School <br />19 <br />Northwest Godinez <br />35.3 <br />35.5 <br />0.2 <br />50.0 <br />High School <br />L <br />,I= 0* Noise SWndatd a rAnd on I Nosa level Q d3 When Exist i rig No me Level e A buye Clay SiAnd�ard <br />Bold =Exceeds Noise standard Thre5huid <br />With the construction of the sound walls, the devellopment of the monitoring well <br />would result in noise levels that would range from a 0.2 dB increase to a 4.9 dB <br />increase.
