On a peak production day, <br /> a conservative estimate for traffic impacts,Table 3.L-38 shows that the proposed <br /> Project will generate 358 truck trips per day in 2027. <br /> Table 3.L-38.

The number of peak daily two-way truck trips that would be <br /> generated by hour was estimated based on the 7,324 two-way truck trips shown <br /> in Table 3.L-38, above. During the AM and PM peak hours,there would be an <br /> increase in two-way truck trips of 33 trips and four trips,respectively. <br /> DeSilva Gates Quarry Project — <br /> Draft Environmental Impact Report 31-32 <br /> J&s 05105 05 <br />
