Section 5 <br />With the construction of the sound walls, the well borehole drilling activities would <br />result in noise levels that would range from a 0, 1 dB increase to a 9.8 dB <br />increase. As shown in Table 49, the construction activity would not exceed the <br />night time noise standard. Potential noise impacts would be less than significant. <br />Phase 4 Construction Activities <br />Phase 4 construction activities would include: Sound Panel Construction and <br />Removal at M!31-2; Conductor Casing Installation at MBI-2; Borehole Drilling and <br />Reaming at MBI-2; Well Construction at MBI-2, and Well Development at MBI-3. <br />Since well development at MBI-3 has the potential to occur simultaneously with <br />the borehole drilling and reamilng at MBI-2, it has been analyzed in combination <br />with the borehole drilling and reaming at MBI-2, <br />MBI-2 Sound Wall Construction <br />The noise levels increases generated from the construction of the sound wall at <br />MBI-2 would range from 0.1 dB increase to an 87 dB increase. As shown in <br />Table 50, the construction activity would not exceed the City's day time noise <br />standard. Additionally, the construction and removal of the sound walls would <br />occur during the day when the construction activity would be exempt under the <br />City's Noise Ordinance. Potential noise impacts would be less than significant. <br />Mid Basin Centennial Park <br />k"LO 8'62 Project Final EIR 5-171 2v�� <br />Fairview Street <br />14 <br />Single Family east <br />66.3 <br />-6-673— <br />0.0 <br />693 <br />Fairview Street <br />15 <br />North Godinez High <br />484 <br />48.4 <br />0.0 <br />50 O <br />School <br />16 <br />Northwest Mitchell <br />37,4 <br />40,8 <br />3A <br />50 _0 <br />School <br />17 <br />North Heritage MUSEUru <br />42.9 <br />43.8 <br />0,9 <br />WO <br />Structure <br />is <br />South Godinez High <br />38.2 <br />38.3 <br />01 <br />50.0 <br />School <br />19 <br />Northwest Godinez <br />35,3 <br />45,0 <br />9.7 <br />50.0 <br />High School <br />I <br />I <br />I =Cliy Noise S fir.indard or ArnbieM Noise lo"I ,3 dS when Exislmg Noise Levels Above Citg Slandar.1 <br />Bold =Fxc ads Nnlse Standard d Threshold <br />With the construction of the sound walls, the well borehole drilling activities would <br />result in noise levels that would range from a 0, 1 dB increase to a 9.8 dB <br />increase.
