Draft Environmental Impact Report Bernal Property Phase II Specific Plan 1 . Framework for Analysis This section discusses the traffic and circulation impacts of the proposed Bernal Property Phase II Specific Plan and the BCP Master Plan, including automobile traffic (traffic gener- ated by the project and its effects on peak hour operations of intersections) and other trans- portation system components (parking, bicycle and pedestrian movement, and transit). Analysis of traffic impacts takes place within the context of Pleasanton's roadway network and the City's existing and projected traffic. As described in the setting section below, Pleas- anton already has numerous intersections at which existing traffic volumes exceed what can be accommodated at the level of service (LOS) called for in the General Plan, which is LOS D. The exceedances of the General Plan standard would occur whether or not the Bernal Property Phase II Specific Plan is adopted and implemented, and the Specific Plan would account for only a minor share of the future traffic projected for these intersections. Never- theless, the Specific Plan's contribution to future deficiencies at these intersections would be considered an adverse impact and, therefore, this transportation analysis has been con- ducted to (1) estimate future project traffic, (2) assign that traffic to roadway links and intersections, and (3) determine the project's level of responsibility for the improvements that may be put in place in the future to improve traffic operations. The analysis of Phase II Specific Plan traffic impacts involves multiple sequential steps, with the conclusions of each step reviewed for reasonableness before proceeding with the next step. The sequence of steps in the traffic analysis for Phase II Specific Plan was as follows: Traffic Task 1) Forecast project related trips Method or Tool Applied Institute of Transportation Engineer (ITE) Manual trip rates were supplemented by specific information on planned uses. Daily and peak hour AM and PM trips were estimated for the each of the Specific Plan's 16 sub-areas (including the Bernal Community Park in sub-area 2) as the aggregate of the trips attracted to or leaving the land uses located in that sub-area. For each of four future scenarios: 2) Assign trips to road network The Pleasanton travel demand model43 was used to distrib- ute daily and peak hour traffic to and from the project site to the future roadway network. 43 The Pleasanton Traffic Model is a comprehensive local traffic model that integrates Pleasanton's roadway network with local land use data in order to be able to accurately assign traffic from potential future projects to the transportation system. 128
