7.D. - Page 49 of 126 Impact 4.10-2: Ground vibration levels resulting from railroad train operations at the setback of proposed residences could exceed appropriate vibration thresholds and could expose people to groundborne vibration. Less than The Final EIR determined that construction under the General significant with Plan would result in less than significant impacts with mitigation implementation of mitigation that requires the preparation of a site-specific vibration study for any residential or vibration - sensitive development proposed within 100 feet of the centerline of the railroad tracks. This mitigation would continue to apply to the areas covered by the proposed project. In addition, several policies and implementation programs in the Public Safety Element of the General Plan would minimize the impacts of temporary construction noise, including Policies PS - 13.6 and PS -13.8 and Programs PS -60, PS -63, and PS -73. These policies require all exterior noise sources to use noise suppression devices to bring noise levels to an acceptable threshold by implementing standard construction noise controls, enforcing existing construction and maintenance hours, and educating construction workers and developers regarding noise reduction measures. The proposed project does not present any changes to these policies and programs. Furthermore, construction activities under the proposed project would be substantially similar to that previously analyzed in the Final EIR. Therefore, no new impact or change in circumstances that would affect the environment would occur. Impact 4.10-3: Estimated increased vehicular traffic and Less than transportation and infrastructure improvements allowed for by significant the General Plan could result in a permanent increase in ambient noise levels. Impact 4.10-4: Construction noise caused by development Less than allowed under the General Plan would cause a temporary or significant periodic increase in noise exposure above ambient levels. Addendum to the Final Environmental Impact Report The land uses in the MULW zoning district was evaluated in the Final EIR, and the proposed project would not allow any new land uses not analyzed in the Final EIR but would allow for increased height and density for projects that incorporate qualified community benefits. There would not be an increase in on-site stationary noise sources, such as heating, ventilation, and air conditioning equipment and systems and utility transformers, under the proposed project. Therefore, the proposed project would result in no new or substantially more severe significant impacts related to conflicts with applicable noise standards beyond those identified in the Final EIR. Since the proposed project contains similar uses that would result in the same traffic impacts as those evaluated (refer to Appendix TRA), it would generate in no new or more severe impacts related to conflicts with applicable noise standards and increases in ambient noise levels and groundborne vibration due to traffic beyond those identified in the Final EIR. Environmental Analysis The proposed project would result in less than significant impacts from vibration. No new or more severe impacts would occur. Impacts would be within the scope of those identified in the General Plan EIR. Similar to the conclusions in the General Plan EIR, the proposed project would result in less than significant impacts from permanent or temporary noise increases. No new or more severe impacts would occur. Impacts would be within the scope of those identified in the General Plan EIR. 33 650
