City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR Construction The 1996 Addendum determined that construction of the proposed modifications would result in the emission of approximately 72 pounds per day (ppd) of CO, 8 ppd of ROG, 75 ppd of NOx, and 119 ppd of PMio, which are below the SCAQMD construction emission thresholds of 550 ppd of CO, 75 ppd of ROG, 100 ppd of NOx, and 150 ppd of PMio. Thus, the 1996 Addendum determined that construction -related air quality impacts would be less than significant. Operation The 1996 Addendum determined that emission levels from operation of the proposed modifications would be above the SCAQMD thresholds for CO, ROG, and NOx, but would be lower than the emission levels identified in the 1983 EIR. Therefore, the proposed modifications would result in fewer air quality impacts than those associated with the Originally Approved Plan. Impacts Associated with the Proposed Project No New Impact. To identify potential air quality related impacts from implementation of the proposed Project, an Air Quality Assessment (AQ 2019), Health Risk Assessment (HRA 2019), and Greenhouse Gas Emissions Assessment were prepared and are included as Appendices F through H, respectively. AQMP Consistency The 2016 AQMP contains air pollutant reduction strategies based on SCAG's growth forecasts, which were defined in consultation with local governments and based upon general plans. The Project site has a General Plan land use designation of District Center and a General Commercial (C2) zoning designation, which provides for a range of commercial uses, as well as all of the uses allowed in the Community Commercial (Cl) zone. The proposed Project would modify the Current Entitlements to reduce the office and commercial uses and add residential uses. This diverse mixture of uses fulfills the purpose of the General Plan's District Center land use designation by adding residential uses in a mixed -use setting. The General Plan's District Center designation allows up to 4,486,074 square feet of mixed uses, inclusive of residential uses, based on the maximum floor area ratio (FAR) of 2.1 over the approximately 49-acre site. As proposed, the Project would result in a District -wide FAR of 2.08, and a density of 39 dwelling units per acre, which is within the maximums allowed in the General Plan. Thus, the proposed Project is consistent with the land use designation and development density presented in the General Plan; and therefore, consistent with the AQMP. In addition, as detailed below, implementation of the Project would not result in greater emissions than were previously anticipated in the 1983 EIR and 1996 Addendum. Therefore, the proposed Project is consistent with the AQMP and impacts related to the AQMP would not occur. 112
