GRANITE CONSTRUCTION COMPANY TRACY EXCAVATION EXPANSION i PAGE 6 3. Overburden/Waste/Ore Sand and gravel excavated from the north side of Corral Hollow Creek would be hauled to approximately station 2+00, where the haul route would cross Corral Hollow Creek before proceeding to a drive over feeder located approximately 200 feet west of the California Aqueduct and 400 feet south of Corral Hollow Creek. Material hauled to the feeder would either be dumped directly into the feeder or temporarily stockpiled immediately west of the feeder. The feeder and stockpile area would occupy approximately 6 acres. The material from the feeder would "feed" onto a conveyor that would cross the California Aqueduct and feed the existing processing plant on the east side of the aqueduct. Sand and eravel from the excavated areas south of Corral Hollow Creek would be hauled by scrapers or rock trucks, to the feeder. The creek crossing would be approximately 30 feet wide and consist of a temporary installation of 3 each- 48" diameter x 40' long corrugated steel culverts covered with 3' of native material. These culverts would be installed no earlier that February 15th and removed no later than October 31st of each year, but in no event would they be installed when the creek is flowing. These culverts would carry any unseasonal storm water flowing in Corral Hollow Creek during the dry season. Material conveyance from the feeder to the processing plant, which is located on the east side of the California Aqueduct, would be by use of a 36" wide conveyor belt. The conveyor would cross the California Aqueduct by means of a steel girder bridge. The conveyor would pass under the California Aqueduct service roads through a pre-cast concrete box culvert. The bridge/conveyor design is attached for your review behind Tab 4.
