Site(s) affected: All (Draft SEIR, pp. 4.J-16 to 4.J-18.) Impact 4.J-2 Construction associated with development facilitated by the General Plan Amendment and rezonings could potentially generate ground-borne vibration at neighboring sensitive uses. The SEIR evaluates the impact of the proposed project related to generate ground-borne vibration at neighboring sensitive uses. Significance Before Mitigation: Significant Significance After Mitigation: Less than Significant Finding: Changes or alterations have been required in or incorporated into the Project that would avoid or substantially lessen the significant environmental effect as identified in the SEIR. Mitigation Measure 4.J-2 which is required in or incorporated into the Project, will reduce the significant environmental impact to a less than significant level. Facts in Support of Finding: The following facts and mitigation measures indicate that the impact will be reduced to less than significant. 1. Vibration exposure at sensitive uses located near construction sites could exceed the applicable criteria in situations where pile driving or similar vibration-producing activity occurs. 2. Implementation of Mitigation Measure 4.J-2 set forth in Table 6-1 of the Final SEIR and listed in the MMRP will ensure that Impact 4.J-2 would be reduced to a less than significant level and is hereby incorporated by reference and described below. 4.J-2: The City shall require developers on the potential sites for rezoning to conduct a vibration study which will estimate vibration levels at neighboring sensitive uses, and if required, provide mitigation efforts needed to satisfy the applicable construction vibration level limit established in Table 4.J-4. It is expected that vibration mitigation for all project sites will be reasonable and feasible. Site(s) affected: All (Draft SEIR, 4.J-18 to 4.J-19.) Impact 44-3 Development facilitated by the General Plan Amendment and rezonings could potentially locate residential uses near an existing rail line. Future residents could potentially be exposed to excessive exterior and interior noise exposure from train noise events.
