4.3.2 Does the Project propose changes that would result in new significant impacts or <br />substantial increase in the severity of significant impacts that will require major revisions <br />of the Certified EIR? <br />The Project includes the demolition and removal of all existing improvements from the Project <br />Site and development of the site with a mixed -use development including up to 507 residential <br />dwelling units, approximately 26,800 square feet of commercial uses, and associated parking, <br />utility infrastructure, landscaping, and open space, all of which is allowed under the Overlay Zone <br />and is consistent with the Overlay Zone standards. The Project does not include any development <br />that would extend beyond the building envelope considered in the Certified EIR, and no changes <br />are proposed to the Overlay Zone to accommodate the Project. As demonstrated below, the <br />Project would incorporate the applicable mitigation measures identified in the Certified EIR and <br />would not result in any new or increased significant air quality impacts beyond those already <br />identified in the Certified EIR. <br />The analysis of the Project's air quality impacts presented below is based on the technical Air <br />Quality Report included as Attachment A. <br />AQMP Consistency <br />Since preparation of the Certified EIR in 2006, the AQMP has been updated. Below is a discussion <br />of the Project's consistency with the 2022 AQMP. <br />As discussed below, the Project's air quality emissions would not exceed any state or federal <br />standards. Therefore, the Project would not increase the frequency or severity of an existing <br />violation or cause or contribute to new violations for these pollutants. As the Project would not <br />exceed any of the state and federal standards, the Project would also not delay timely attainment <br />of air quality standards or interim emission reductions specified in the AQMP. <br />With respect to the determination of consistency with AQMP growth assumptions, the projections <br />in the AQMP for achieving air quality goals are based on assumptions in SCAG's 2020-2045 <br />RTP/SCS regarding population, housing, and growth trends. Determining whether or not a project <br />exceeds the assumptions reflected in the AQMP involves the evaluation of three criteria: (1) <br />consistency with applicable population, housing, and employment growth projections; (2) project <br />Mitigation Measures; and (3) appropriate incorporation of AQMP land use planning strategies. <br />The following discussion provides an analysis with respect to each of these three criteria. <br />• Is the project consistent with the population, housing, and employment growth <br />projections upon which AQMP forecasted emission levels are based? <br />A project is consistent with the AQMP, in part, if it is consistent with the population, housing, and <br />employment assumptions that were used in the development of the AQMP, which are based on <br />SCAG's 2020-2045 RTP/SCS. <br />SCAG's 2020-2045 RTP/SCS provides socioeconomic forecast projections of regional population <br />Cabrillo Town Center City of Santa Ana <br />Technical Memorandum August 2023 <br />City Council 18 — 509 10/3/2023 <br />
