City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR 5.15 IRREVERSIBLE ENVIRONMENTAL CHANGES Summary of Impacts Identified in the 1983 EIR The 1983 EIR described that the Originally Approved Plan would result in an intensification of land uses and consumption of energy from fossil fuels and building materials that are irreplaceable. In addition, the EIR describes that increased vehicular traffic, related air emissions and noise would result. Similarly, a permanent commitment to provide increased services to the site would occur. Furthermore, the EIR described that the visual character of the site would be altered, and shade/shadow impacts would result. Summary of Impacts Identified in the 1996 Addendum The 1996 Addendum does not include a discussion of irreversible environmental changes. Impacts Associated with the Proposed Project No New Impact. Consistent with the Originally Approved Plan, the proposed Project would result in or contribute to the following irreversible environmental changes: • Lands would be committed to new uses once the proposed buildings are constructed. • Changes in views associated with the new buildings, parking structures, and landscaping. • Increased traffic on area roadways. • Emissions of air pollutants • Consumption of non-renewable energy from automobiles, lighting, heating and cooling systems, appliances, etc. • Increased ambient noise associated with an increase in activities and traffic. Regarding energy, as described previously, the proposed Project would not involve wasteful or unjustifiable use of non-renewable resources, and conservation efforts would be enforced during Project permitting. The Project would incorporate energy conserving project design features pursuant to current Title 24 standards. Regarding shade/shadow, as described previously, the proposed Project's building heights would not generate shadows upon residential areas, which was identified as a potentially significant impact of the Originally Approved Plan. Therefore, irreversible environmental changes related to shade/shadow from the Originally Approved Plan would not occur by the proposed Project. Thus, impacts from the proposed Project would be less than those identified in the 1983 EIR. In addition, as described throughout this Addendum, implementation of the proposed Project would not result in any other of greater environmental impact that could result in an irreversible environmental change. 159
