San Joaquin County Community Environmental Seting,Impacts,and Mitigation Measures _ <br /> Development Department Transportation and Traffic <br /> 2027 Traffic Operations <br /> Traffic operations data for year 2027 follows the same format and SR 132/Bird — <br /> Road Interchange assumptions as data presented for 2007 baseline operations. <br /> The year 2027 baseline AM and PM peak hour traffic volumes for each <br /> interchange alternative are shown on Figure 15 in Appendix F. _ <br /> Intersection Operations <br /> Table 3.L-20 presents the projected year 2027 base conditions intersection — <br /> operations for the worst-case intersection alternative. As shown in Table 3.L-20, <br /> the SR 132 ramp intersections with Bird Road are projected to operate at LOS <br /> "C"or better during both the AM and PM peak hours under all three design <br /> alternatives. As also shown in Table 3.L-20,Blewett Road intersections with <br /> Bird Road and Koster Road are projected to operate at LOS`B"or better during <br /> both peak hour periods(Omni-Means 2005). <br /> Table 3.L-20.

The first segment(referred to as Location 1 — <br /> in Table 3.L-21) is the weave on westbound SR 132 between the southbound 1-5 <br /> direct off-ramp to westbound SR 132 and the westbound SR 132 off-ramp to <br /> Bird Road. The second segment(referred to as Location 2 in Table 3.L-21) is the — <br /> weave on eastbound SR 132 between the Bird Road on-ramp and the eastbound <br /> SR 132 direct off-ramp to southbound 1-5. As shown in Table 3.L-21,weave <br /> sections are projected to operate at LOS "D"on westbound SR 132 during the _ <br /> AM peak hour and LOS "D"on eastbound SR 132 during the PM peak hour <br /> (Omni-Means 2005). <br /> DeSilva Gates Quarry Project <br /> Draft Environmental Impact Report 31-18 <br /> J8s 05105.05 <br />
