Alternative 1: Proposed Project <br /> Table 4.6-5 shows the existing and project-related,peak hour traffic volumes for various <br /> roadways in the vicinity of the project site, and increase in peak hour noise levels along <br /> those roadways resulting from-the proposed project. According to the EIR transportation <br /> consultant, the proposed operation would generate a maximum rate of approximately 150 <br /> loads (or 300 truck trips) per day. About 20 of those loads (i.e., 40 trips) would occur i <br /> during the peak hour. k <br /> Table 4.6-5 <br /> Predicted Peak Hour Traffic Volumes and Noise Levels <br /> Alternative 1 <br /> Peak Hour Truck <br /> Roadway Segment Volumes' Truck Noise Level Increase, <br /> Existing Project dB <br /> Koster Project to Blewett 4 40 10 <br /> Blewett to SR 132 8 36 7 <br /> Blewett Bird to Koster 2 2 3 <br /> East of Koster 4 2 2 <br /> Bird Blewett to SR 132 4 2 2 <br /> SR-132 East of Koster 164 4 0 <br /> Koster to 1-5 169 32 1 <br /> West of 1-5 177 12 0 r <br /> 1-5 North of SR 132 313 20 0 <br /> 1- Estimated from information provided by the EIR transportation consultant and Caltrans traffic <br /> counts. <br /> Table 4.6-5 data indicate that significant traffic noise level increases are expected along <br /> Koster Road as a result of the proposed project. This is due to the fact that existing truck <br /> traffic on Koster Road is very light, and because all of the project truck traffic would be on <br /> Koster Road, between the project site and Blewett Road, and 90% of the project-generated <br /> truck traffic would be on Koster Road, between Blewett Road and State Route (SR) 132. <br /> Truck traffic noise level increases on other roadways would not result in significant traffic. <br /> noise level increases. <br /> Despite the fact that project-generated truck traffic would significantly increase truck traffic. <br /> noise levels along Koster Road, south of SR 132, there were no noise sensitive land uses <br /> identified along this segment to be affected by the increase. In addition, the truck traffic <br /> noise level at a reference distance of 100 feet from Koster Road was predicted using the <br /> FHWA model to be approximately 60 dB Lam, during the a.m. peak hour. Therefore, off-site <br /> truck traffic associated with the proposed project is not expected to result in significant <br /> noise impacts at existing noise-sensitive land uses in the project vicinity. <br /> Draft Environmental Impact Report 4-94 ER-96-3 <br />
