I DKS Associates Executive Summary This report analyzes the traffic impacts associated with the implementation of the Bristol Street Specific Plan compared with the impacts associated without implementation. The study also discusses the guidelines for establishing design standards for the spacing of driveway access locations and street intersections. The report also discusses the residential impacts due to traffic i congestion on Bristol Street. The study area is comprised of a north/south corridor centered around Bristol Street within the City of Santa Ana. The proposed plan involves upgrading land uses along this corridor with parks and landscaping, along with several new commercial developments. The traffic impacts associated with the proposed specific plan represent a net decrease in projected traffic volumes compared to the General Plan. The traffic generation for the site accounts for both the reduction in traffic due to the lane reconfiguration according to the General Plan as well as the decrease in traffic attributable to the proposed land uses such as parks and landscaping. For the entire study area, approximately 7,000 daily trips are generated by the site which is a reduction from the 16,350 daily trips generated by the General Plan. Approximately 700 trips are projected to be generated during the PM peak hour for the Specific Plan compared to the 1,600 trips without the Specific Plan. Analysis Thirteen intersections have been included in the analysis. Operating conditions have been analyzed at these intersections based on the Intersection Capacity Utilization (ICU) Operational Analysis Methodology for the following scenarios: 1, Existing traffic and existing lane configurations (Figure 3 -2). 2. General Plan traffic for the year 2006 with approved future lane configuration (Figure 4 -1). 3, Specific Plan traffic and trip generation with the future lane configuration. Table ES -1 provides a comparison of total trip generation by zones for the future condition with and without the Specific Plan, while Table ES -2 presents a summary of levels of service for the three scenarios. i For the existing condition, the intersections of Bristol Street at Memory Lane, 17th Street and 1st Street are not functioning at acceptable levels. The intersection of Bristol Street at Memory Lane functions at a level of service E during both peak hours, The intersection of Bristol Street at 17th Street functions unsatisfactorily during the PM peak hour at level of service F. In contrast, the intersection of Bristol Street and 1st Street does not function satisfactorily iP during the AM peak hour at a level of service E. i 28657.P9022WRpt FS -1 75C -521
