San Joaquin County Community Environmental Setting,Impacts,and Mitigation Measures <br /> Development Department Transportation and Traffic <br /> include analysis of the reduced traffic that would occur as facilities are <br /> constructed and initial excavations occur. By 2027,yearly aggregate production <br /> was estimated to increase to 800,000 tons per year. These estimates do not _ <br /> include the 100,000 tons per year of inbound material to be recycled;however, <br /> the increase in traffic volumes,approximately two to three additional inbound <br /> and two to three additional outbound trips for 2027 AM peak hour and about one <br /> additional inbound and one additional outbound trip for 2027 PM peak hour, or — <br /> changes in operations due to recycling at the project site were not significant <br /> enough to change the results of the traffic analysis(Joe Weiland pers. comm.) <br /> 2007 Estimated Project Truck Trip Generation Rates and <br /> Volumes <br /> Estimated Truck Trips <br /> As shown below, the proposed Project will generate an average of 160 truck trips <br /> per day in 2007 based on the average 2007 production rate of 500,000 tons per <br /> year. <br /> Table 3.L-26.

To account for the estimated peak production,the average _ <br /> daily truck loads shown in Table 3.L-26 (above)were adjusted up by a factor of <br /> 1.4. The resulting estimated peak daily truck generation from the proposed <br /> DeSilva Gates quarry in 2007 is shown in Table 3.L-27. On a peak production <br /> day, Table 31-16 shows that the proposed Project will generate 224 truck trips <br /> per day in 2007. <br /> DeSilva Gates Quarry Project <br /> Draft Environmental Impact Report 31-24 <br /> AS 05105.05 <br />
