DEVELOPMENT PLAN 1 2 2.6 Circulation and Mobility 2.6.1 Vehicular Circulation Vehicular circulation is comprised of two components: peripheral public roadways and internal private drives. In connection with the previous MainPlace Mall entitlements, the developer was required to make and/or fund a number of significant infrastructure improvements designed to accommodate the traffic expected to be generated by the full implementation of the original project analyzed in the Final EIR. As recognized by the City in a 1996 EIR Addendum, all improvements required as traffic mitigation measures in the Final EIR were completed prior to 1996, with the exception of funding a pair of new freeway ramps linking the Santa Ana Freeway to Main Place Drive. That measure was determined to be infeasible, and replaced with an obligation to contribute to the cost of other ramps then planned by Caltrans, as documented in a 1992 amendment to the Participation Agreement between the City's Redevelopment Agency and the MainPlace Mall developer. The alternative ramps identified in the amended Participation Agreement, consisting of an off -ramp from southbound I-5 to Broadway and an on -ramp from Main Street to northbound I-5, were thereafter constructed. Accordingly, all of the traffic improvements the Agency and City determined were necessary to accommodate the original project have been implemented. The circulation components of the plan include the following (see Figure 2-9, Cross Section and Figure 2-10, Circulation Plan): A. Main Street Main Street provides the primary access to the Specific Plan area and represents the site's eastern boundary. Main Street is identified in the City's Circulation Element as a public Major Arterial. A Major Arterial generally consists of six travel lanes with a right-of-way of 120 feet. According to the Master Plan of Streets and Highways (MPSH), this type of roadway is designed to accommodate between 33,900 and 50,600 trips daily. Main Street is constructed to its ultimate right-of-way along the project frontage; with six lanes, multiple turn lanes, and both painted and raised medians. Three driveways into the site are present along Main Street, providing access to parking structures and surface parking lots. The driveways may be reconfigured as part of individual development projects along the eastern edge of the Specific Plan area, but no new driveways are planned. Three signalized intersections with existing crosswalks are present on the Main Street edge of the property: one at Main Place Drive/Town and Country, a second at the parking structure entrance/East City Place Drive, and a third at Main Place Drive/Memory Lane (see Figure 2-10, Circulation Plan). Q. Main Plare Driv- Main Place Drive is a local public street, with a modified section due to its proximity to SR 22 and Interstate 5 and to the existing mall and parking structures. Main Place Drive is constructed as a four -lane public road, with several turn lanes and painted medians but no sidewalks. Main Place Drive functions as a loop, intersecting with Bedford Road on the north, Broadway on the south, and Main Street in two locations. Improvements to Main Place Drive are limited to the following: Vacation of Main Place Drive, a public right-of-way, between Bedford Road and Main Street. A new private drive aisle will be constructed in a different configuration, connecting Main Place Drive to its current intersection with Main Street. The new private drive aisle consists of approximately 1.4 acres while the vacated right-of-way consists of approximately 1.1 acres up to 172.24' in elevation. The property owner owns the air rights above that right-of-way above 172.24' in elevation. The abandonment of this road segment may include a vacation action by the City and/or quit -claim.
