Cemex Vemal's Quarry Mining and Reclamation Project After review of the admiftistfative draft of the EIR, it was determined by San joaquin Cetil4� staff that U 1 Reate Option 2 will not be supported by st..1T Presentation ..f the analyse — performed fef Hatt! Route Option 2 femains in the report at!he fequest of the app ileam. The anticipated project traffic volumes and distribution are shown in Figures 7 through 10 (in Appendix C)for Haul Route Options 1 and 2 3 respectively. The distribution of project traffic to the adjacent road network was determined based on discussions with the project Applicant and County staff during a project site walk-through. Future ' Cumulative Traffic Volumes _ The San Joaquin County travel model is maintained by the San Joaquin County Council of Governments(SJCCOG). The model includes peak-hour directional travel volume estimates for the base year 1999 and for the future year 2025. Travel model data provided by SJCCOG is presented in Appendix C. The future peak-hour volumes were estimated based on the Increment Method described in the Council of Fresno County Governments Recommended Procedures for Using Traffic Projections from the Fresno COG Travel Model,dated January 2002. Although the — Increment Method was developed for the Fresno County model, it is the opinion of Peters Engineering Group that the methods are applicable to other travel models. The IncrementMethod estimates the future growth in traffic volumes by determining the difference between the year _ 2025 travel model and the base year travel model volumes. This difference indicates the growth in traffic volumes that is predicted by the model between the base year and the year 2025. This growth is then added to the existing volumes determined by actual traffic counts. Future turning movements were determined based on the methods presented in Chapter 8 of the Transportation Research Board National Cooperative Highway Research Program Report 255 titled"Highway Traffic Data for Urbanized Area Project Planning and Design." In some instances,the travel model predicts negative growth.However,a minimum annual growth _ rate of 2.5 percent was maintained for each turning movement.Because travel models can be unreliable in rural areas,this minimum growth rate was applied to maintain a conservative approach to the anticipated growth in traffic volumes.Based on data provided in the Draft Environmental Impact _ Report dated September 10, 1993 by ESA for the Granite Construction Company project,the average daily traffic volume on State Route 132 was 13,500 in 1992.Data available on the Caltrans web site (<www.dot.ca.gov/hghrafops/saferesr/trafdata/>)indicates an average daily traffic volume of — approximately 18,000 in 2002.This equates to an average annual growth rate of 2.9 percent. Therefore,a minimum annual growth rate of 2.5 percent for each turning movement was applied in cases where the model predicts less than 2.5 percent annual growth.
