City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR determined to be infeasible. As a result, the measure was replaced with an obligation to contribute to the cost of other ramps then planned by Caltrans that included an off -ramp from southbound 1-5 to North Broadway and an on -ramp from Main Street to northbound 1-5, which were thereafter constructed. In addition, Mitigation Measure 5.6-3, which required Main Street to be widened to an eight -lane roadway, was superseded by the General Plan Circulation Element, which identifies Main Street as a 6-lane major arterial. During update of the General Plan Circulation Element in 1998, the City determined that widening of Main Street is not necessary to accommodate build out of the Original Project. Thus, all of the traffic improvements the Redevelopment Agency and City determined were necessary to accommodate the Original Project have already been implemented. Summary of Impacts Identified in the 1996 Addendum The 1996 Addendum described that the expansion modifications are not anticipated to result in any additional significant impacts compared to those identified in the 1983 EIR. The 1996 Addendum determined that the mitigation measures identified in the 1983 EIR served to mitigate a much larger project than the 1996 proposed expansion and no additional mitigation measures were required. Impacts Associated with the Proposed Project No New Impact. To identify potential traffic and circulation impacts from implementation of the proposed Project, a Traffic Impact Study (TIS 2019) was prepared and is included as Appendix D. Specifically, the Traffic Impact Study considered whether reducing the buildout of the site by 859,255 square feet of commercial and office space, and adding to the buildout of the site 1,900 residential units, resulted in a new traffic impact, or a substantially more severe traffic impact, than was disclosed in the 1983 EIR. The analysis found that implementation of the proposed Project would result in fewer daily vehicular trips than build out of the existing land use entitlements for the Project site; and as a result, no new traffic impacts would occur from implementation of the proposed Project, as detailed below. Significance Thresholds The Level of Service (LOS) standard for peak hour intersection operations for the Cities of Santa Ana and Orange, and for Caltrans is LOS D; with the exception of Santa Ana intersections within a designated Major Development Area (MDA) where the LOS standard is LOS E. The acceptable LOS standard —and the definition of "deficient' LOS—for operations within the City of Santa Ana is adopted and established by the City of Santa Ana General Plan. For intersections under the jurisdiction of the City of Santa Ana or the City of Orange, Project impacts are considered to be significant if the project -related traffic causes a deficient LOS; or if the intersection is already deficient, the project -related traffic 70
