06/07/2004 Mitigation: The Project shall obtain an acoustical study for its multifamily residential component, and shall install noise insulation features and other elements approved by the City which will reduce interior noise to or below state and City standards (Mitigation 13 -1). Findings: Mitigation 13 -1 is feasible, and noise exposures at or below the permitted levels would be below the level of environmental significance. B. Construction - Induced Vibration Potential Impact: Project pile- driving could cause ground -borne vibration that would damage nearby structures or interfere with daily activities (Impact 13 -2). Mitigation: The Project shall conduct vibration - generating construction activity only between 7:00 a.m. and 7:00 p.m. Monday through Friday, notify (in writing) occupants of land uses within 200 feet of the schedule for pile- driving activities, and pre- drill pile holes or use other techniques of equivalent effect (Mitigation 13 -2). Findings: Mitigation 13 -2 is feasible and would reduce the effects of vibration on nearby structures and sensitive receptors to a level of insignificance. C. Construction Noise Potential Impact: Project demolition and construction would temporarily increase noise levels for residences near the Project and for previously completed Project residences that could intermittently interfere with residential activities and could exceed City standards (Impact 13 -3). Mitigation: The Project shall incorporate in project demolition and construction activities the construction period noise abatement measures set forth in Mitigation 13 -3. Findings: Mitigation 13 -3 is feasible and would substantially reduce most of the potentially significant construction noise impacts. However, the impact would remain significant and unavoidable. There is no other feasible mitigation measure available to avoid or substantially reduce the noise impacts described above. The remaining impact could be eliminated only by not proceeding with large parts of the Project, which is infeasible and would prevent the environmental, economic, social and other benefits of the Project more fully described above. XI. CULTURAL AND HISTORIC RESOURCES Potential Impact: Implementation of the proposed grading plan for the Project could disturb sensitive, on -site, subsurface cultural resources which are not identifiable at the current stage of development (Impact 14 -1). 1289 \02 \179278.2 33 Atty /Reso /Reso.1470 14590 060804 Muff # 304 Bin 26
