Section 5 <br />With the construction of the sound walls, the development of the monitoring well <br />would result in noise levels that would range From a 0.1 dB increase to a 10.8 dB <br />increase. As shown in Table 70, the development of the monitoring well would <br />not exceed the City's day time noise standard. Additionally, the development <br />activities For of the monitoring well would occur during the day when the <br />construction activity would be exempt under the City's Noise Ordinance. Potential <br />noise impacts would be less than significant. <br />Table 71: Monitoring Well Development Night Time Noise levels <br />Receiver <br />Fairview Street <br />Existing <br />Existing + <br />increase <br />Threshold <br />14 <br />Single Family east <br />71 A <br />71.4 <br />0,0 <br />74.4 <br />1 <br />Fairview Street <br />34.6 <br />34,8 <br />0.2 <br />50.0 <br />15 <br />North Godinez High <br />53,6 <br />53.6 <br />Ll.d <br />55.0 <br />2 <br />School <br />54,.5 <br />545 <br />0.0 <br />57.5 <br />16 <br />Northwest Mitchell <br />43.5 <br />48.1 <br />4,8 <br />55.0 <br />3 <br />School <br />58.11 <br />58.1 <br />10 <br />61.1 <br />17 <br />North Heritage <br />48.1 <br />52,1 <br />40 <br />550 <br />4 <br />Museum Structure <br />57.0 <br />57,0 <br />0.0 <br />60.0 <br />18 <br />South Godinez High <br />43.3 <br />54.1 <br />10.8 <br />55.0 <br />5 <br />School <br />57,3 <br />57.3 <br />0.0 <br />60.3 <br />19 <br />Northwest Godiinez <br />46.2 <br />46.4 <br />02 <br />55.0 <br />6 <br />High School <br />64.3 <br />54.3 <br />0,0 <br />67.3 <br />I= City Nose, StarxMrd w Ambient Noise level +3 JS WIion Existing N e Levels Abeve City Sondaid <br />Bolus = Exceeds Noise Silmdard 7fireshold <br />With the construction of the sound walls, the development of the monitoring well <br />would result in noise levels that would range From a 0.1 dB increase to a 10.8 dB <br />increase.
