complies with EPA/CARB Tier 3 emissions standards, would also be required to reduce construction emissions below a level of significance. No new or greater impacts related to construction air quality would occur from implementation of the Modified Project. Air Quality Plan Impacts Consistent with the Original Project, the Modified Project is consistent with SCAG’s population, housing, and employment forecasts because the 256 new multi-family units that would be developed by the Modified Project would constitute a 0.33 percent increase in the total number of residential units in the City, and a 1.0 percent increase in the number of the multi-family residential units (5+ units) within the City, which is within the Southern California Association of Governments (SCAG) projected growth. In addition, the Modified Project would also support Air Quality Management Plan (AQMP) objectives to reduce trips, promote infill development, and balance jobs and housing. Therefore, no new or greater impacts related to air quality plans would occur from implementation of the Modified Project. Operational Impacts As the Modified Project would reduce the number of multi-family residential units that would be developed on the site by 48.4 percent, the stationary source emissions that would be generated by the residences would also be reduced. Similarly, Section 3.11, Transportation and Traffic, of this document details that operation of 278 multi-family units, (which is 22 more units than the Modified Project’s proposed 256 units and thus provides an overstated and conservative analysis of potential impacts), would result in 1,186 fewer daily vehicular trips than the Original Project. The reduction of vehicular trips would correlate directly to a reduction of vehicular emissions being generated by operation of the site. As described previously, the Original Project’s maximum daily operational emissions would not exceed any of SCAQMD’s daily significance thresholds. Thus, the Modified Project, which would result in 240 fewer residential units and 1,186 fewer daily vehicle trips would also not result in a violation of an air quality standard or substantially contribute to an existing or projected air quality violation. Therefore, no new or greater impacts related to operational air quality emissions would occur from implementation of the Modified Project. Conclusion for Air Quality Consistent with the Original Project, the Modified Project would generate air quality emissions from construction and operation of the proposed multi-family residential units. However, the same construction mitigation would reduce impacts to a less than significant level and the Modified Project would constitute growth that is consistent with the AQMP. In addition, because the Modified Project is 48.4 percent smaller than the Original Project, it would result in fewer stationary source and vehicular related emissions. Based on the foregoing, none of the conditions identified in CEQA Guidelines Section 15088.5 that would trigger the need to prepare a recirculated EIR or other environmental document exist. The Modified Project would not result in either a new significant environmental impact or a substantial increase in the severity of a previously identified impact. EIR Mitigation Measure Mitigation Measure AQ-1: Construction plans and specifications shall state that the construction contractor shall use off-road diesel construction equipment that complies with EPA/CARB Tier 3 emissions standards and shall ensure that all construction equipment be tuned and maintained in accordance with the manufacturer’s specifications. 3.3 Biological Resources Summary of Impacts Identified in the EIR Section 4.3, Biological Resources, of the EIR describes that the 180 mature ornamental trees on the Project site provide potentially suitable foraging and breeding habitat for nesting migratory birds and raptor species.
