such an event occurs and permit the river to fallow the <br />historic main channel. As stated in the Buckhorn Geotech <br />information, "This will prevent impacts to adjoining <br />property that could be caused by impeding the flow". <br />4b. PURPOSE <br />The excavated sand and gravel will be loaded directly into <br />trucks and hauled offsite to be used for road-base and/or fill <br />at various construction sites. The project will be <br />intermittant, with excavation and hauling conducted on an <br />"as-need" basis for various projects. <br />An equipment storage area and warehousing within trailer <br />units currently exists on the property. This area will be used <br />for both the gravel operation and the current uses while the <br />project is being conducted, so there will not be a need far <br />additional facilities. <br />It is estimated that 15,000 yd3 of material will be <br />removed annually. The project is to be a five-year operation, <br />with possible renewal during the fifth year. The starting date <br />will be as soon as permitting will allow, with a completion <br />date in five years. <br />4c. DISCHARGE OF DREDGED OR FILL MATERIAL <br />Material excavated with the front-end loader will be <br />loaded directly into trucks and hauled offsite. The temporary <br />diversion structure in Phase II will be constructed with native <br />• alluvium and is estimated to require 650 yd3. By allowing the <br />channel to remain within the Phase I excavated area during <br />Phase 11, stockpiles will not be needed for the operation. <br />The rip-rap to be used for the project will be acquired <br />from construction projects elsewhere. Approximately 2000 yd~ <br />will be required and will be stockpiled on the property as it <br />becomes available. <br />Page 4 (Application) <br />
