EXHIBIT C • PRE-MINING PLAN AND MINING PLAN MAP OF AFFECTED LAND (Part of Explanation of Request on County Application) Overview The is a request of mine sand material Yrom a 45+ acre parcel located 7 mile north of Byers. The 45+ acres is located along West ~ Bijou Creek, where sand has been deposited. The 45+ acre area is part of a larger 160± acre property owned by the applicant. The permit area has no structures on it, although there is a barn a 1/4± mile to the west located on the same property. In this area was also some miscellaneous junk that the County required to be removed prior to beginning excavation. This junk has been removed. ~ The material would be exported for use in foundation backfill projects, and County or State Highway projects in the area. There is also the possibly the material could be used in the construction of the two airports to the west (Denver International and Front Aange). Since export of material off of the property is involved, County land-use approvals are necessary as in a MLRB permit. Existing Site Description The site is located 7± miles north of Byers, 5± miles north of the U.S. 36 (County line), and 1/4± mile west of the County road known as Calhoun-Byers Mile Road. The site is a fairly level one, except ~ for the draw area created by the intermittent flowing of West Bijou Creek which traverses the proposed permit area. The total elevation fall over the distance of the site !1/8± mile east-west x 1/2± mile north south) is approximately 15+ feet. The site is located in the draw which has been formed by the Creek and is not easily visible from the County Road. ~ The permit area itself can be divided into three basic areas: 1. The south 100' is where a 30' access road from the County road traverses the permit area and previous excavation has been undertaken. The area mined for sand in the past was prior to permits being required, and for uses on the property recently. ~ For instance, sand from the excavation area was used as foundation fill for the barn structure on other portions of the property. This access road will remain after excavation to provide access to the western portion of the property where the barn is located. • 2. The second basic area of the permit area, is the bare usually dry West Bijou Creek channel area approximately 100' wide, which traverses the permit area from south to north. The channel is a dry creek bed which only runs after upstream storm events, usually in the spring and early summer. There is no topsoil and the surface is predominantly bare sand with little if any vegetation, except for some volunteer cottonwood ~ trees along the edges. ~~
