area estimated that approximately 68 percent of future residents of the area would work in the Bay Area. Based upon this, it is assumed that approximately 50 percent of the trips generated by the proposed project would be oriented to the Bay Area, 45 percent to the central area of the City of Tracy and the remaining five percent to Interstate 5 via Eleventh Street and Kasson Road. The assignment of project related traffic to the surrounding roadway network is shown in Figure 3.3-2. Future trips which would be generated by buildout of the surrounding area were distributed and assigned to the roadway network in the same manner. Capacity Analysis. Traffic volumes and roadway levels of service (LOS) were projected and evaluated for two future scenarios. Scenario 1 assumes existing traffic volumes plus traffic which would be generated by the proposed project. Scenario 2 assumes Scenario 1 plus traffic which would be generated by buildout of the surrounding 384 acres with construction of an additional 205 single family residential units. The results of the analysis are summarized in Table 3.3-2. Review of Table 3.3-2 will indicate that all roadways evaluated are expected to continue to operate at an LOS A assuming Scenario 1. MacArthur Drive is expected to realize a daily increase in traffic volumes of 103 vehicles; Linne Road, an increase of 30 vehicles; Fairoaks Road, an increase of 70 vehicles; and Chrisman Road, an increase of 10 vehicles. However, all are projected to continue to operate at an LOS A. Completion of Scenario 2, buildout of the surrounding area, would further increase traffic volumes on surrounding roadways as indicated in Table 3.3-2. However, all roadways are forecast to continue to operate at an LOS A. Transit. The proposed project should be expected to generate a very limited public transit ridership due to the existing limited service to the area. Use of the existing County Area Transit (CAT) service in the area is restricted to the elderly and handicapped. To the extent the proposed project would be inhabited by elderly or handicapped, the system would probably be used. However, no significant diversion of trips to public transit should be expected to occur until a more substantial public transit service is provided to the area. Ridesharing in the form of carpooling or vanpooling would probably provide a more effective and less costly means of reducing vehicle trips in the project area. Carpooling could be utilized for work related trips, particularly to the San Francisco Bay Area as well as for recreational, school or shopping related trips to the City of Tracy. Vanpooling could be utilized for work commuting to the San Francisco Bay Area. Site Access/Parking. Access to the project site would be provided at a single point to Fairoaks Road as shown in Figure 1-3. Plans are not sufficiently detailed at this time to allow a comprehensive review of the proposed project roadways and intersections. However, as more detailed plans become available, they should be reviewed by the County to ensure adequate roadway geometrics and driver sight distance are provided. The plans should also be reviewed to ensure adequate circulation to other portions of the study area. The Public Works Department considers the single access point to be unacceptable (Gau, 1987). 3.3-7
