area for disposal . The anticipated excavation life of this project will be approximately 12 months more or less . It is largely dependent on the availability of the equipment needed to remove the material and the seasonal weather conditions if not completed before winter begins . The site is currently used as rangeland and consists of the northwest side of a gravel terrace above the Colorado River Valley to the west and the Smith Creek on the north. The mate- rial depth ranges from 0 to 50 feet deep . The soil covering the gravel averages 0 to 14 inches deep over the material to be removed. The material generated is waste as far as the operator is concerned but it will likely be processed into construction material or used as pit run fill material by the company removing it . Initially, an area on the north end of the level area will be stripped of soil and leveled to create a storage place for the material hauled to the site under the old backfilling plan. Until it is placed on the building envelope to cover the underlaying gravely floor . Any soil stripped will be stored along the east mine setback or on the north stockpile area for use in reclaiming the east slope and provide a temporary sight berm for the neighbor to the east . Material removal will start on the high point of the mine near the south line and work west and north. Scrapers will be used to removed and haul the material to the disposal area on the adjoining mine . The plan is to then removed the west and south sides of the permit area so the floor of the site will be approx- imately 5 feet above the floor of the adjoining mine . This will leave the building envelope area nearly level and ready for building . A private road will be built to access the house along The south side of the permit area . Reclamation Ridge LLC and Daniel and Donna Hahn have agreed to "day lighting" out the slopes that would be left on their side of the property line so an artificial ridge is not left between properties . This will leave a temporary north facing slope on the Thompson Resource mine (Hahn property) that would be removed when that area is mined. The east slope will be graded 3 : 1 and the north undis- turbed area and slope below the development floor will remain in its natural state . No blasting will take place in this mine . A 10-foot mining limit setback line will be established by grading a ditch parallel to the east permit line . Because of the way the material will be removed there will be no working face on the mine . The scrapers will be taking the top of the material off with each pass so the working area will gradually be lower Track 4 Grading Project June 11, 2020 23
