a2.0 PROJECT LOCATION AND DESCRIPTION The Bristol Widening Project includes the widening and improve- ment of a 4 mile portion of Bristol Street, between Warner Avenue and Memory Lane, in the City of Santa Ana. The project will be partially funded through the Federal Aid Urban (FAU) Program. The project will require CEQA and NEPA clearances as well as review by CalTrans for compliance with their Local Programs Manual. Thus, City, State and Federal requirements must be met. Figure 1 depicts the project location in its regional context. Figures 2 and 3 illustrate the Area of Potential Environmental Impact (APEI) with a dashed line. The APEI generally extends one lot depth on either side of Bristol Street. The land uses abut- ting Bristol Street in this area are shown in Figures 4 and 5. Bristol Street presently exists as a 4 -lane or 5 -1ane divided roadway within the project limits. Right -of -way acquisition and roadway widening will be accomplished in conjunction with the ! proposed project. Three alternatives for right -of -way acquisi- tion are under consideration. They include: (1) even acquisition from both sides of the roadway, (2) acquisition only from the east side of the roadway, and (3) acquisition only from the west side of the roadway. Additional land acquisition will occur at the intersections of Bristol Street with Memory Lane, Seventeenth Street, Civic Center Drive, and First Street, to accommodate exclusive right turn lanes. The proposed cross - sections will provide a fully improved divided major highway per City standards with: sidewalks, curbs and gutters, six through lanes, and a raised landscaped median. Additionally, there are planned modifications of traffic signals and relocation of other improvements at existing intersections. The proposed improvements will comply with the provisions of the Circulation Element of the Santa Ana General Plan. Along the entire length of the project a 102 -foot curb -to -curb width is proposed within a 120 -foot right --of -way. Table 2 -1 provides the existing and proposed roadway improvements, lane geometrics, and rights -of -way along Bristol Street within the APEI. Table 2 -2 shows the anticipated changes in average route speeds ( i.e. running speeds as opposed to posted speed limits or spot speeds) and vehicle miles travelled (VMT) along the 3.75 mile roadway segment under study. As shown therein, future design year (2006) running speeds without the project will be signifi- cantly lower than current and future "build" running speeds because of the increased traffic demands. The proposed widening project will improve running speeds and thereby, reduce conges- tion. ir 2 -1 r
