As this could significantly increase the number of trucks, and as how this could be a condition that could last for a month or more, a peak adjustment factor was developed to reflect this condition. The peak daily truck generation was developed based on estimated peak month production information provided by the applicant and other individual quarry operators. The review of this information resulted in an average peak daily production estimate that is approximately 40- percent higher than the average daily production. To account for the estimated peak production, the im average daily truck loads shown in Table 7 were adjusted up by a factor of 1.4. The resulting estimated peak daily truck generation from the proposed DeSilva Gates quarry both at start- up and by the year 2027 is shown in Table 8. On a peak production day, Table 8 shows that the proposed project will generate 224 truck trips per day at start-up increasing to 358 truck trips per day by the year 2027 resulting in an increase of 134 additional peak daily truck trips.

As shown in the table, approximately 25% of the trucks generated by the proposed project are estimated to have origins/destinations to the northwest via I-580, 50% are estimated to have origins/destinations to the north via I-5, 10% are estimated to have origins/destinations to the south via 1-5, and 15% are estimated to have origins/destinations to the east via SR-132.
