San Joaquin County Community Environmental Setting,Impacts,and Mitigation Measures _ <br /> Development Department Transportation and Traffic <br /> Ramp Junction (Merge/Diverge) Operations <br /> Table 3.L-23 presents the projected Bird Road on-ramp merge with westbound <br /> SR 132 and eastbound SR 132 off-ramp diverge to Bud Road for the worst-case _ <br /> design alternative. SR 132 was considered to be a four-lane freeway at the merge <br /> and diverge. As shown in Table 3.L-23, the on-ramp merge from Bird Road to <br /> westbound SR 132 is projected to operate at LOS "F"during the AM peak design <br /> hour for all three design alternatives. As also shown in the table,the off-ramp <br /> diverge from eastbound SR 132 to Bird Road is projected to operate at LOS"F" <br /> during the PM peak design hour(Omni-Means 2005). <br /> Table 3.L-23.

As shown in the table,the westbound SR 132 segments to the <br /> east,to the west,and within the Bird Road interchange are projected to operate at <br /> LOS "E/F"during the AM peak hour. As also shown in the table,the eastbound — <br /> SR 132 segments both to the east,to the west and within the Bird Road <br /> interchange are projected to operate at LOS "E"during the PM peak hour. Table <br /> 3.L-24 also shows that LOS "E"is projected on westbound SR 132 during the <br /> AM peak hour,and LOS`B"is projected on eastbound SR 132 from the I-5/SR <br /> 132 interchange east to the end of the four-lane freeway segment while the two- <br /> lane highway segment on SR 132 further east of the 1-5/SR 132 interchange is — <br /> projected to operate at LOS "F"during both peak hours. Finally,all three non- <br /> state highway facilities including Bird Road,Koster Road and Blewett Road are <br /> projected to operate at LOS "C"or better during both peak hour periods(Omni- <br /> Means 2005). <br /> DeSilva Gates Quarry Project <br /> Draft Environmental Impact Report 31-20 <br /> ass 05[05.06 <br />
