EXHIBIT I <br />Soils Information <br />According to the Soil Survey of Weld County, Colorado, Southern Part (United States <br />Department of Agriculture, Natural Resource Conservation Service, Web Soil Survey <br />1.1 National Cooperative Soil Survey), there are three major soil types within the <br />proposed project site: <br />1. Aquolls and Aquents, gravelly substratum <br />2. Ustic Torriorthents, moderately steep <br />3. Bankard Sandy Loam, 0 to 3 percent slopes <br />The location of these soil types is illustrated on the following attached map. <br />Aquolls and Aquents, gravelly substratum <br />This map unit is typically on bottom lands and flood plains of major streams. Aquolls <br />make up about 60% of the unit and are dark colored at the surface. Aquents have a <br />lighter color surface layer and make up 35% of the unit. The other 5% is Aquepts and <br />Bankard sandy loam. <br />The soils of this land type are deep, poorly drained soils that formed in recent alluvium. <br />The water table is at or near the surface early in spring and recedes to as deep as 48 <br />inches in the fall in certain years. These soils are used for rangeland and wildlife habitat. <br />Some areas have been reclaimed by major drainage and leveling and are used for <br />irrigated crops. These soils have good potential as a source of sand and gravel. <br />The potential native vegetation is alkali sacaton, switchgrass, and western wheatgrass. <br />Saltgrass, sedge, rush, and alkali bluegrass are also prominent. As range condition <br />deteriorates the saltgrass, sedge, and rush increase. <br />Ustic Torriorthents, moderately steep <br />These are deep and excessively drained soils on terrace breaks and escarpments at <br />elevations of 4,450 to 5,100 feet. The soil formed in gravelly alluvium with slopes of 9 to <br />25 percent. The surface of the soil is pale brown gravelly sand about ten inches thick. <br />The underlying material is pale brown gravelly sand to a depth of 60 inches. <br />The permeability of the soil is rapid and the available water capacity is low. Surface <br />runoff is medium and the erosion hazard is moderate. <br />The potential native vegetation is little bluestem, sideoats grama, sand reedgrass, blue <br />grama, hairy grama, switchgrass, and need leandthread. Deteriorated range conditions <br />allow the tall and mid grasses decrease. Blue grama and hairy grama will increase in <br />deteriorating conditions. <br />4 M Derr Pit Project <br />J&T Consulting, Inc. DMG 112 Permit <br />32
