EXHIBIT A With the implementation of the mitigation measure identified above (MM-HAZ-1), the Project's potential impacts relating to hazards and hazardous materials would be less than significant. (DEIR, pp. 4.6-7 through 4.6-8.) 8.4 Noise 8.4.1 Noise Levels in Excess of Established Standards Threshold: Would the Project result in exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Finding: Less than significant impact with mitigation incorporated. (DEIR, pp. 4.8-10 through 4.8-13.) Facts in Support of Findings: The Project would not result in generation of noise levels in excess standards established by the City's Municipal Code. Per Section 18-314 (Special Provisions) of the City's Municipal Code noise sources associated with construction activities are exempt from the established 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 weekdays, including Saturday, or any time on Sunday or a federal holiday. The Project's construction activities would occur pursuant to these regulations. Thus, the Project would be in compliance with the City's construction related noise standards. However, the Project has the potential to result in exposure of persons to noise levels in excess of relevant standards as a result of increased traffic -related noise. As discussed in the DEIR, traffic along the roadways near the Project site would generate noise that could exceed interior noise standards within some of the Project units. Thus, some of the residential units would require upgraded windows and sliding glass doors with increased Sound Transmission Class (STC) ratings to meet the interior noise standards. As described in Section 4.8, Noise, of the DEIR, the residential units along N. Main Street would require upgraded windows and sliding glass doors with minimum STC ratings of between 27 and 30 to meet the interior noise standards. Mitigation Measure NOH would ensure that the appropriate windows and doors are installed, which would reduce impacts to a less than significant level. (DEIR, pp. 4.8-10 through 4.8-13.) Mitigation Measure N0I-1: The Project plans and specifications shall include the following construction requirements to be implemented and verified prior to provision of occupancy permits: • Windows/Glass Doors: Residential units adjacent to N. Main Street (all floors) require upgraded windows and sliding glass doors (all windows/doors on all floors) with minimum STC ratings of 30; and all other buildings require standards windows and sliding glass doors with a minimum STC rating of 27. Exterior Doors (Non -Glass): Exterior doors facing N. Main Street (all floors) require upgraded exterior doors with minimum STC ratings of 30 and shall be well weather-stripped; and all other residential building exterior doors shall be well weather-stripped and have minimum STC ratings of 27. Well -sealed perimeter gaps around the doors are essential to achieve the optimal STC rating. Walls: At any penetrations of exterior walls by pipes, ducts, or conduits, the space between the wall and pipes, ducts, or conduits shall be caulked or filled with mortar to form an airtight seal.
