FINDINGS ON POTENTIALLY SIGNIFICANT IMPACTS <br />A. IMPACTS MITIGATED TO LESS THAN SIGNIFICANT <br />The following summary describes impacts of the proposed project that, without mitigation, would <br />result in significant adverse impacts. Upon implementation of the mitigation measures provided <br />in the Draft EIR, these impacts would be considered less than significant. <br />Air Quality <br />Impact 5.1 -4 Construction activities associated with the proposed project could expose <br />sensitive receptors to substantial pollutant concentrations of coarse <br />particulate matter (PM10). <br />Facts in Support of Finding: Support for this environmental impact conclusion is fully <br />discussed starting on page 5.1 -16 of Section 5. 1, Air Quality, of the Draft EIR. <br />The maximum daily emissions of PM10 generated during demolition and debris - hauling activities <br />would exceed the PMto LST. Consequently, impacts to localized air quality from project - related <br />construction activities would be potentially significant. <br />Mitigation Measure <br />AQ -1 Prior to construction contract award, the City of Santa Ana shall specify in the <br />constriction special provisions that the construction contractor shall include <br />limitations on the amount of roadway debris to be removed from the site. During <br />demolition of the roadway including asphalt, roadbed, curb, gutter, and sidewalks, <br />the contractor shall limit the daily amount of demolition debris haul to a maximum of <br />38 trucks per day if 12 -ton capacity haul trucks are used, assuming a one -way haul <br />distance of 9 miles. If truck haul distance for roadway debris is greater than 9 miles, <br />CEQA Findings of Fact -6- <br />Warner Avenue Improvements & Widening from Main Street to Grand Avenue Aug 2015 <br />•7 <br />
