City of Santa Ana Addendum to the MainPlace Mall Transformation Project Fashion Square Commercial Center Final EIR located in the southwest portion of the site and not cast shadows to Residential Area "B". The buildings proposed to be located adjacent to 1-5 would not exceed 10 stories, pursuant to the development regulations in the Specific Plan. Therefore, no shade/shadow impacts would occur in Residential Area B. No new impact would occur. Residential Area C is the residential area located to the north of SR-22. The1983 EIR states: "A building from 19 to 52 stories tall could be located along the northern Project boundary before any shadows were cast to Residential Area 'C'." As part of the proposed Project, the maximum proposed building height is 20-stories along Main Street and 10-stories elsewhere onsite, pursuant to the development regulations in the Specific Plan. Therefore, no shade/shadow impacts would occur in Residential Area C. No new impact would occur. As described previously, the 1983 EIR concluded that development on the Project site could have significant and unavoidable shade/shadow impacts. However, the Project's proposed building heights would not generate shadows upon residential areas. Therefore, impacts related to shade/shadow impacts would be less than those identified in the 1983 EIR and the same as those identified in the 1996 Addendum. In addition, Mitigation Measure 5.9-1 from the 1983 EIR, which provides for a shade and shadow analysis to reduce potential impacts would not be applicable to the proposed Project, given that the Specific Plan's development plan restricts building locations and heights such that no impact would occur. Solar Glare Reflective light (glare) can be caused by sunlight or artificial light reflecting from finished surfaces such as window glass or other reflective materials. Generally, darker or mirrored glass would have a higher visible light reflectance than clear glass. Buildings constructed of highly reflective materials from which the sun reflects at a low angle can cause adverse glare. The proposed Project would not use highly reflective surfaces, nor be comprised of glass sided buildings. Although the buildings would contain windows, the windows would be separated by brick, cement, stucco, or similar type of sided building wall that would limit the potential of glare. The Specific Plan Design Guidelines include the following requirements that reduce the potential for glare: DG - 63 All materials for exterior applications should be finished. Inappropriate materials for exterior applications include: (a) Plastics/Plastic Laminates (b) Asphalt shingles (c) Corrugated fiberglass, or plastic (d) Plywood or similar (e) Highly reflective materials 129
