San Joaquin County Community Environmental Setting,Impacts,and Mitigation Measures <br /> Development Department Transportation and Traffic <br /> 3.L Transportation and Traffic <br /> Introduction <br /> This section describes existing transportation setting in the project area;presents <br /> the applicable state and local policies and regulations that determine mitigation <br /> requirements; and identifies impacts associated with implementation of the <br /> proposed project. Potential impacts of project alternatives on transportation and <br /> traffic are described and analyzed in Chapter 4, "Alternatives Analysis." <br /> The following key source of data and information was used in the preparation of <br /> this section. <br /> ■ DeSilva Gates Quarry Traffic and Circulation Analysis prepared by Omni- <br /> Means and included as Appendix F to this draft EIR <br /> Environmental Setting <br /> Physical Setting <br /> This section describes roadways and intersections in and near the project area. <br /> The location of roadways in the region and their relationship to the project area <br /> are shown in Figure 2-2. <br /> The current quarry operations in the project region use the Bird Road intersection <br /> with SR 132 to gain access to the state highway system. The County currently <br /> prohibits any aggregate truck traffic from using Koster Road south of SR 132 for <br /> truck access to and from existing quarry sites. This prohibition is assumed to <br /> remain in place through the foreseeable future. The County intends that all <br /> aggregate truck traffic use Bird Road and the SR 132/Bird Road interchange for <br /> access to the state highway system. <br /> State Highways <br /> I-5,1-580,and in particular SR 132 will be used for the proposed project to <br /> transport materials from the mine to customers in the surrounding region. These <br /> regional connectors are described below. <br /> ■ I-5 is an interstate north-south freeway that begins at the Califomia/Mexico <br /> border south of San Diego and ends at the Washington State/Canada border. <br /> It serves as the primary north-south interstate route through the San Joaquin <br /> and Sacramento Valleys. Just south of the project area,I-5 intersects with I- <br /> 580 at a freeway-to-freeway interchange. I-5 is a four-lane freeway in the <br /> DeSilva Gates Quarry Project <br /> Draft Environmental Impact Report 3.L-1 <br /> J85 05105.0.5 <br />
