SECTION IV IMPACTS MITIGATED TO A LEVEL OF LESS THAN SIGNIFICANT The City hereby finds that mitigation measures have been identified in the Supplemental EIR that would avoid or substantially lessen the following potentially significant environmental impacts to a less than significant level. The potentially significant impacts and the mitigation measures that would reduce them to a less than significant level are detailed in the Supplemental EIR and summarized below. A. Air Quality Impact Finding: The Project would not expose sensitive receptors to substantial pollutant concentrations (Draft Supplemental EIR at p. 5.1-32). Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant environmental effect identified in the Draft Supplemental EIR Facts in Support of Findings: The nearest offsite sensitive receptor to the Phase 1 construction area is a multi -family residential building located approximately 130 feet (40 meters) to the west. The nearest offsite sensitive receptor to the Phase 2 construction area is a multi -family residential building located 410 feet (125 meters) to the north. The nearest offsite sensitive receptor to the Phase 3 construction area is a multi -family residential building located 130 feet (40 meters) to the west. Construction Phase 1 Table 5.1-23 of the Draft Supplemental EIR identifies daily localized onsite emissions that are estimated to occur during construction of Phase 1 of the proposed Project. As shown, emissions during the peak site preparation and grading construction activity of Phase 1 would exceed the SCAQMD's localized significance thresholds for NOx and PM2.5. However, as described previously GPU FEIR Mitigation Measure AQ-1 for GARB Tier 4 Final off -road construction equipment standards would reduce NOx emissions and Project Mitigation Measure AQ-1, Construction Exhaust and Dust Control, would reduce PM2.5 emissions to below the SCAQMD thresholds for localized significance, as shown in Draft Supplemental EIR Table 5.1-24. Therefore, LST impacts from construction of Phase 1 would be less than significant with incorporation of mitigation (Draft Supplemental EIR at pp. 5.1-32 through 5.1-33). Construction Phase 2 Table 5.1-25 of the Draft Supplemental EIR identifies daily localized onsite emissions that are estimated to occur during construction of Phase 2 of the proposed Project. As shown, emissions during the peak site preparation and grading construction activity of Phase 2 would exceed the SCAQMD's localized significance thresholds for NOx and PM2.5. However, as described previously GPU FEIR Mitigation Measure AQ-1 for CARE Tier 4 Final off -road construction equipment standards would reduce NOx emissions and Project Mitigation Measure AQ-1, Construction Exhaust and Dust Control, would reduce PM2.5 emissions to below the SCAQMD thresholds for localized
