and height of sound walls /walls shall be determined based on the conclusions of the final acoustical report and the final pad elevations of the grading plan. All walls determined to be necessary for noise mitigation by the final acoustical report shall be incorporated into the final roadway construction plans. Finding: Changes or alterations have been required in or incorporated into the project that avoid or substantially lessen the significant environmental effect identified in the Final EIR. These changes are identified in the form of a mitigation measure, presented above. Impact 5.8 -1 would be less than significant with mitigation. The City of Santa Ana hereby finds that implementation of the mitigation measure is feasible, and it is therefore adopted. Impact 5.8 -2 Construction activities would expose sensitive uses to groundborne vibration levels that would be perceptible and potentially cause architectural damage at homes. Facts in Support of Finding: Support for this environmental impact conclusion is fully discussed starting on page 5.8 -16 of Section 5.8, Noise, of the Draft EIR. Groundborne vibration would be generated by the proposed project during construction activities, primarily during the demolition, grading, and foundation phases. At a distance of 25 feet, vibration levels generated by a vibratory roller would exceed the FTA threshold and would have the potential to cause architectural damage at existing structures. Mitigation Measure N -2 The use of vibratory rollers shall be prohibited within 30 feet of a residential structure. If soil compacting is required within 30 feet of a residential structure, static rollers shall be employed. Finding: Changes or alterations have been required in or incorporated into the project that avoid or substantially lessen the significant environmental effect identified in the Final EIR. These changes are identified in the form of a mitigation measure, presented above. Impact 5.8 -2 would be less than significant with mitigation. The City of Santa Ana hereby finds that implementation of the mitigation measure is feasible, and it is therefore adopted. Transportation and Traffic Impact 5.10 -6 Project construction may require additional temporary safety measures to assure safe routes to schools for elementary schools next to the project site. Facts in Support of Finding: Support for this environmental impact conclusion is fully discussed starting on page 5.10 -28 of Section 5.10, Transportation and Traffic, of the Draft EIR. There are two schools next to the project site: James Monroe Elementary School at 417 East Central Avenue along the south side of Warner Avenue near its intersection with Oak Street; and Manuel Esqueda Elementary School at 2240 South Main Street at the northwest corner of the intersection of Warner Avenue and Main Street. Temporary changes to roadway and intersection configuration during project construction, including changes to crosswalks and pedestrian crossing signals, may require additional, temporary safety measures for students and other CEQA Findings of Fact -9- Warner Avenue Improvements & Widening from Main Street to Grand Avenue Aug 2015 75B -21
