City of Santa Ana Addendum to the MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR 5.6 TRAFFIC AND CIRCULATION Summary of Impacts Identified in the 1983 EIR The 1983 EIR included a traffic impact analysis that included an evaluation of the capacity of arterial streets and freeways that would be utilized by vehicular trips generated by the Originally Approved Plan. The analysis determined that buildout of the Originally Approved Plan would require the following specific roadway improvements to reduce traffic impacts from buildout of the site: 1. Contribute a one percent (1 %) assessment fee to the Joint City of Santa Ana and City of Orange Transportation System Improvement Program (TSIP) to fund needed transportation improvements in the area. 2. Provide funding for the construction of freeway ramps on the west side of Fashion Square to link the Santa Ana Freeway with a public road surrounding the Project. 3. Widen Main Street along the Fashion Square frontage to provide 4 southbound lanes and a 26-foot-wide median island to accommodate dual northbound left - turn lanes. 4. Construct a public roadway around the west side of the site from the intersection of Owens Drive (now Memory Lane)/North Broadway to the intersection of Main Street/Town and Country Road. 5A. Modify the intersection of the Mall Entrance at Main Street to accommodate two entry and exit lanes, a left -turn pocket, and left -turn phasing. 5B.

Install traffic signals at the intersection of La Veta Avenue at Bedford Road and at the intersection of Bristol Avenue/La Veta Road at the SR-57 southbound off - ramp. 7. Develop and maintain a Transportation System Management (TSM) Program to maximize use of transit, ride -sharing and staggering of work hours. 8. Provide second -level access from a future transit station on Main Street to minimize at -grade pedestrian crossings of Main Street. However, the 1983 EIR determined that even with implementation of the improvements listed above, a significant impact on streets and freeways would result, and that full development of the site would require completion of other local street and freeway improvements to accommodate the traffic. After certification of the 1983 EIR, six of the eight mitigation measures listed above were implemented with construction of the approved structures. Mitigation Measure 5.6-2, which required the developer of the Mall to "[p]rovide funding for the construction of a pair of new freeway ramps on the west side of Fashion Square linking the Santa Ana Freeway with a public road surrounding the project' (the future Main Place Drive), was o;
