structure. If soil compacting is required within 30 feet of a residential structure, static rollers shall be employed. N -3 Prior to the start of grading, the construction contractor shall provide evidence acceptable to the Public Works Director, or designee, that: a. All construction vehicles and equipment, fixed or mobile, shall be equipped with properly operating and maintained mufflers; mufflers shall be equivalent to or of greater noise reducing performance than manufacturer's standard. b. Stationary equipment, such as generators, cranes, and air compressors, shall be located as far from adjacent residences and James Monroe Elementary School as feasible. c. Equipment maintenance, vehicle parking, and material staging areas shall be located as far away from adjacent residences and James Monroe Elementary School as feasible. N -4 The recommended sound walls described in N -1 shall be constructed as soon as practicable to minimize temporary construction - related noise impacts during implementation of the project. 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. The City of Santa Ana hereby finds that implementation of the mitigation measure is feasible, and it is therefore adopted. Mitigation Measures N -1 through N -4 would reduce noise generated by construction activities to the extent feasible. However, due to the amount of heavy construction equipment required and duration of construction activities, Impact 5.8 -3 would remain significant and unavoidable and a Statement of Overriding Considerations is required. Transportation and Traffic Impact 5.10 -3 Project construction may result in temporary impacts to levels of service at Warner Avenue /Main Street and Warner Avenue/Halladay Street intersections. Facts in Support of Finding: Support for this environmental impact conclusion is fully discussed starting on page 5.10 -26 of Section 5. 10, Transportation and Traffic, of the Draft EIR. The analysis detennined that three studied intersections would continue to operate at acceptable LOS D or better and two intersections would operate at unacceptable LOS: Main Street and Warner Avenue at LOS E during PM peak hour, and Halladay Street and Warner Avenue at LOS F during PM peak hour. Additionally, because the Maple Street and Warner Avenue intersection is unsignalized, the delay would be worsened in the north and south directions. These impacts would be temporary, and traffic flow would improve once the construction is complete. Short- term roadway closures would occur during removal and relocation of overhead electrical poles.
