Section 5 <br />Phase ? Night Time Construction Activities <br />The noise levels generated from the construction of the water supply pipeline and <br />back flush pipeline during the night within Centennial (Park are shown in Table <br />37. The construction activities would exceed the night time noise standard at <br />Receiver 10, 15, and 19. All of the sensitive receptors are school facilities. The <br />Construction activity would occur at night when the schools would not be in <br />session. Because no sensitive receptors would be present, potential construction <br />noise impacts would be less than significant. <br />Table 37: Phase One Construction Activities Night Time Noise Levels <br />Receiver <br />Education Center�� <br />Exlsitng <br />; ,Exiistnig+ <br />AncreAse <br />x(1)14 Iss' <br />10 <br />Southeast <br />54,8 <br />55.5 <br />0.7 <br />55.0 <br />Centennial <br />Throatiraiit; <br />1 <br />Education Center <br />34.6 <br />41.7 <br />7.1 <br />50 <br />11 <br />Single Family east <br />71.8 <br />71.9 <br />0.1 <br />74.8 <br />2 <br />Fairview Street <br />54.5 <br />54.6 <br />0,3 <br />57.5 <br />12 <br />Singie Family east <br />71.3 <br />71.4 <br />0.1 <br />74.3 <br />3 <br />Fairview Street <br />58.1 <br />58.7 <br />0,6 <br />61.1 <br />13 <br />Single Faimily east <br />71.3 <br />71.4 <br />0.1 <br />74.3 <br />Fairview Street <br />14 <br />Single Family east <br />71.4 <br />71.4 <br />0.0 <br />74.4 <br />Fairview Street <br />15 <br />North Godinez High <br />516 <br />54.4 <br />0.8 <br />55.0 <br />School <br />16 <br />Northwest Mitchell <br />43.5 <br />61.1 <br />17.6 <br />55.0 <br />School <br />17 <br />North Heritage <br />48.1 <br />61.6 <br />13.5 <br />55.0 <br />Museum Structure <br />18 <br />South Godinez <br />43.3 <br />58.1 <br />14.8 <br />55.0 <br />High School <br />19 <br />Northwest Godinez <br />44 ,2 <br />51.5 <br />5.3 <br />55.0 <br />High School <br />1 -City Noise s anderd Dr Ambient Noise level t! dE when Existing Nn,se Levels Above City Slanderd <br />Bold =Exoaeds Noise Standard Thoeshnld <br />Phase ?
