City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR Conclusion for Housing and Population The proposed Project would not result in difficulties finding affordable housing, and the Project would result in fewer potential impacts than were identified in the 1983 EIR; and the same, less than significant impacts that were identified in the 1996 Addendum. Thus, no new or substantially greater impacts would occur with implementation of the proposed Project when compared to those identified in the 1983 EIR or 1996 Addendum. Based on the foregoing, none of the conditions identified in CEQA Guidelines section 15162 that would trigger the need to prepare a subsequent or supplemental EIR or other environmental document to evaluate Project impacts or mitigation measures exist regarding housing and population. There have not been 1) changes to the Project that require major revisions of the previous adopted EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified effects; 2) substantial changes with respect to the circumstances under which the Project is undertaken that require major revisions of the previous adopted EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified effects; or 3) the availability of new information of substantial importance relating to significant effects or mitigation measures or alternatives that were not known and could not have been known when the 1983 EIR was adopted as completed. Mitigation Measures No mitigation measures related to housing and population were included in the 1983 EIR and none are required for the proposed Project. 5.12 JOHN WAYNE AIRPORT Summary of Impacts Identified in the 1983 EIR The 1983 EIR described that the Project site is located outside of the 60 CNEL noise contour for John Wayne Airport and is over one -mile from the airport's approach and horizontal surface, but was within an area that requires a determination from the Federal Aviation Administration (FAA) of the aeronautical hazard of structures that intrude into an aerial imaginary horizontal surface of 203 feet above the sea level. With a ground elevation of 145 feet above sea level, FAA approval was required for structures over 58 feet in height. Summary of Impacts Identified in the 1996 Addendum The 1996 Addendum described that the addition would not create any new hazards to aircraft approaching or departing the airport, and that no significant impacts would occur. 140
