EXHIBIT A <br />Resolution No. _____ Page 15 of 71 <br />Certification of the Magnolia at the Park EIR <br /> <br /> <br />With the implementation of the mitigation measure identified above (MM-HAZ-1), the Project’s potential <br />impacts relating to hazards and hazardous materials would be less than significant. (DEIR, pp. 4.6-7 <br />through 4.6-8.) <br /> <br />8.4 Noise <br /> <br />8.4.1 Noise Levels in Excess of Established Standards <br /> <br />Threshold: Would the Project result in exposure of persons to or generation of noise levels in <br />excess of standards established in the local general plan or noise ordinance, or applicable standards of <br />other agencies? <br /> <br />Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-10 through 4.8-13.) <br />Facts in Support of Findings: The Project would not result in generation of noise levels in excess <br />standards established by the City’s Municipal Code. Per Section 18-314 (Special Provisions) of the City’s <br />Municipal Code noise sources associated with construction activities are exempt from the established <br />noise standards as long as the activities do not take place between the hours of 8:00 p.m. and 7:00 a.m. on <br />weekdays, including Saturday, or any time on Sunday or a federal holiday. The Project’s construction <br />activities would occur pursuant to these regulations. Thus, the Project would be in compliance with the <br />City’s construction related noise standards. <br /> <br />However, the Project has the potential to result in exposure of persons to noise levels in excess of relevant <br />standards as a result of increased traffic-related noise. As discussed in the DEIR, traffic along the roadways <br />near the Project site would generate noise that could exceed interior noise standards within some of the <br />Project units. Thus, some of the residential units would require upgraded windows and sliding glass doors <br />with increased Sound Transmission Class (STC) ratings to meet the interior noise standards. As described <br />in Section 4.8, Noise, of the DEIR, the residential units along N. Main Street would require upgraded <br />windows and sliding glass doors with minimum STC ratings of between 27 and 30 to meet the interior <br />noise standards. Mitigation Measure NOI-1 would ensure that the appropriate windows and doors are <br />installed, which would reduce impacts to a less than significant level. (DEIR, pp. 4.8-10 through 4.8-13.) <br /> <br />Mitigation Measure NOI-1: The Project plans and specifications shall include the following <br />construction requirements to be implemented and verified prior to provision of occupancy permits: <br />• Windows/Glass Doors: Residential units adjacent to N. Main Street (all floors) require upgraded <br />windows and sliding glass doors (all windows/doors on all floors) with minimum STC ratings of <br />30; and all other buildings require standards windows and sliding glass doors with a minimum <br />STC rating of 27. <br />• Exterior Doors (Non-Glass): Exterior doors facing N. Main Street (all floors) require upgraded <br />exterior doors with minimum STC ratings of 30 and shall be well weather-stripped; and all other <br />residential building exterior doors shall be well weather-stripped and have minimum STC ratings <br />of 27. Well-sealed perimeter gaps around the doors are essential to achieve the optimal STC rating. <br />• Walls: At any penetrations of exterior walls by pipes, ducts, or conduits, the space between the <br />wall and pipes, ducts, or conduits shall be caulked or filled with mortar to form an airtight seal. <br />2-51
