Peak Traffic Times - To better understand the worst-case traffic condition at the two alternative sites, staff and consultants have evaluated the time period when the most intensive use of the Arts Center would occur. This is important to understand because it gives a general sense as to when and how much overall traffic the Center will generate. A persons per vehicle ratio of 1:2.5 was used to help project the number of round trips created by each of the CAC users. The worst-case traffic scenario is generally expected to occur at infrequent times from April through October on Wednesday through Sunday in the early evening. This is the time range when the Arts Center facility use is estimated to reach the following combined peak occupancy shown below. It was assumed that performance in the amphitheater and indoor theater will not take place at the same time. Amphitheater Art Classrooms Art Gallery Rehearsal Space Theater 100%occupancy 50%occupancy 50%occupancy 50%occupancy 0%occupancy This occupancy scenario would result in a projected total of approximately 470 vehicles (not including support staff) arriving at the Center between 6 and 7 p.m. Alternative Site Traffic Analysis - The following analysis is the result of the above assumptions. This analysis is only intended to be preliminary in nature for level of magnitude comparison purposes. A detailed traffic analysis for both sites will be included in the upcoming Draft Environmental Impact Report for the Phase II Specific Plan. The Valley Avenue site alternative proposes vehicular access connections to Valley Avenue, Bernal Avenue, and Laguna Creek Lane. The primary traffic matters raised by each of these points of access are as follows: Valley Avenue Access - · Use of northbound Valley Avenue would accommodate most traffic to Bernal Avenue, 1-680, and greater Pleasanton destinations. Use of southbound Valley Avenue to northbound Pleasanton Avenue would also serve motorists heading to east and north Pleasanton. · The existing roundabouts on Valley Avenue would substantially slow and potentially congest theater traffic during pre and post-performance peak traffic periods. · The Valley Avenue/Bernal Avenue signalized intersection was constructed with turn lanes to accommodate large volumes of traffic such as from theater performances.
