Several irrigation ditches cross the property, including <br />Lupton Bottom Ditch, Meadow Island Ditch No. 1, and the Brighton Ditch. No primary <br />ditches will be relocated and offsets will be maintained according to the Geotechnical <br />Stability Exhibit. <br />Much of the proposed area is located within the 100-year flood boundary. Base flood <br />elevations and flood hazard factors have been determined, see enclosed FEMA maps. <br />Topography <br />Topography may be characterized as flat to very gently sloping over the areas proposed for <br />mining. Current site topography is shown on the Pre-mining Plan Map. Surface slopes aze <br />generally to the northeast. <br />Area of Affected Lands <br />The proposed permit area covers 1,368 acres. The total area expected to be disturbed <br />including mine areas, temporary overburden and topsoil stockpiles, and access roads is <br />approximately 1,064 acres. <br />Vegetation <br />The site has historically been used for agriculture, including livestock grazing and <br />agricultural crops. Upland areas vary greatly throughout the site; however, the majority <br />consist of irrigated cropland including corn, onion, mustard, cabbage, and hay. <br />Wetlands Delineation <br />A request for Assessment of Jurisdictional Determination has been submitted to the United <br />States Army Corps of Engineers (Corps). A wetland jurisdictional delineation study has <br />been conducted on the site; this study can be found in Exhibit J. A majority of the wetlands <br />occur along the South Platte River corridor and will no[ be impacted by mining operations. <br />Lafarge intends to avoid jurisdictional wetlands where possible; however, if disturbance is <br />necessary appropriate Corps permits will be obtained. <br />Permanent or Man-Made Structures <br />All permanent or man-made structures are shown on the attached map, and a list of the <br />structure owners can be found in Exhibit S. <br />DMC /12 Permit <br />Poge 8 of 81 <br />
