12/16/2019 • The contractor shall be required to prepare a schedule for major noise -generating construction activities. The construction plan shall identify a procedure for coordination with adjacent residential land uses so that construction activities can be scheduled to minimize noise disturbance. • Designate a "disturbance coordinator" who would be responsible for responding to any complaints about construction noise. The disturbance coordinator would determine the cause of the noise complaint (e.g., bad muffler, etc.) and would require that reasonable measures be implemented to correct the problem. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include in it the notice sent to neighbors regarding the construction schedule. MM N0I-1.2: Mechanical equipment shall be selected and designed to reduce impacts on surrounding uses to meet ambient noise conditions at the nearest residential land uses during both daytime and nighttime conditions. A qualified acoustical consultant shall be retained to review mechanical noise as these systems are selected to determine specific noise reduction measures necessary to comply with the City's noise level requirements. Noise reduction measures could include, but are not limited to, selection of equipment that emits low noise levels and/installation of noise barriers, such as enclosures and parapet walls, to block the line -of -sight between the noise source and the nearest receptors. Alternate measures may include locating equipment in less noise -sensitive areas, such as indoors or the rooftop of the buildings away from the building's edge nearest the noise -sensitive receptors. The City finds that Mitigation Measures NOI-1.1 and N0I-1.2 are feasible, are adopted, and will further reduce impacts associated with this issue to a level of less than significant. Accordingly, the City finds that, pursuant to Public Resources Code section 21081(a)(1) and State CEQA Guidelines section 15091(a)(1), changes or alterations have been required in, or incorporated into, the proposed project that mitigate or avoid the potentially significant impacts of the proposed project related to this issue. Impact N0I-2: The project would result in generation of, excessive groundborne vibration or groundborne noise levels. Finding: The project, in compliance with General Plan Program PS -63 and with the implementation of mitigation measures MM N0I-1.1 and MM N01-2. 1, would reduce noise impacts from constriction -related vibration to a less than significant level. (Less than Significant Impact with Mitigation Incorporated) Changes or alterations have been required in, or incorporated into, the Project, which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, section 15091(a) (1).) Facts in Support of Finding. The project, in compliance with General Plan Program PS -63 and with the implementation of mitigation measures MM N0I-1.1 and MM N01-2. 1, would reduce construction -generated vibration levels at the residences to the west of the project site to a less than significant level by limiting construction hours, prohibiting use of heavy vibration -generating equipment near residences to the west, and informing heavy equipment operators to be cognizant of activities near residences to the west (pages 123-124 of the Draft EIR) MM N0I-2.1: In addition to the noise controls outlined in General Plan Program PS -63 and mitigation measure MM N0I-1.1, the project shall implement the following measures where vibration levels due to construction activities would exceed 0.3 in/see PPV at nearby sensitive uses: • Prohibit the use of heavy vibration -generating construction equipment within 20 feet of the structures located adjacent to the project site.
