<br />Andesite Rock Co. proposes to operate a sand & gravel <br />operation on the referenced site. The site contains a size- <br />able quantity of material that will have a market in the <br />Denver metro area in the years to come. The quality of this <br />material is significantly higher than that of the alluvial <br />deposits that remain on the Platte River basin in Denver. <br />The facility would normally employ eight to ten people <br />full-time. Should there be a need to set up a temporary <br />concrete or asphalt batch plant, that number could double. <br />Work would be done on a two-shift basis, with the evening <br />shift being primarily maintenance. Production and load- <br />out would occur during daylight hours. <br />The extraction and processing of materials in the pit <br />will be as follows: <br />Topsoil will first be bladed into windows in a 200-ft. <br />wide area, with the long axis being north-south. Approx. <br />2 ft. of overburden will be removed next with a 20-yard <br />elevating scraper. Initially, this material will be stock- <br />piled to the east of the cut, but will be placed directly <br />on the sand or undersized material once the initial cut <br />is made. The windrowed topsoil will be picked-up by the <br />scraper immediately after the overburden is in place. <br />As soon as enough topsoil and overburden are removed, <br />excavation will proceed on the same north-south axis at an <br />initial width of approx. 100 ft. and depth of approx. 8 ft. <br />with a 7-yard front-end loader. The loader will feed a <br />portable scalping screen, which will reject all material <br /> <br />
