<br />Unit 34 <br />• Exhibit I <br />Table I-1. Soils Dr <br />Name Fort Collins loam, 1 to 4 percent slopes <br />Description <br />This deep, well drained soil is on plains and fan terraces. It is formed in medium textured alluvium. The <br />native vegetation is mainly grasses. Fine-loamy, mixed mesic Ustollic haplargids: non-hydric. <br />The surface layer is typically pale brown loam about 4 inches thick. The subsoil to a depth of 60 inches <br />or more is loam. The soil is neutral to a depth of 15 inches. It is mildly alkaline to a depth of 21 inches <br />and moderately alkaline below that depth. <br />Permeability is moderate. Available water capacity is high. Effective rooting depth is 60 inches or more. <br />Runoff is slow or medium, and the hazard of water erosion is slight or moderate. <br />The soil is used as rangeland or for hay and pasture. The potential plant community is mainly blue <br />grama, western wheatgrass, and sideoats grama. The average annual production of air-dry vegetation <br />is about 800 pounds per acre. If the condition of the range deteriorates, blue grama, red threeawn, and <br />pricklypear increase. <br />The capability classification is II-e, irrigated, and VI-c, nonirrigated. The soil is in the Loamy Plains ak6 <br />range site. <br />Unit 52 <br />Name Kim-Cascajo complex, 2 to 15 percent slopes <br />Description <br />Note: exists only in the roadside buffer zone and included for completeness only. <br />These soils are on breaks in areas where stream terace cut through fans and fan terraces. The native <br />vegetation is mainly grasses. The unit is about 50 percent Kim soil and 34 percent Cascajo soil. The <br />Kim soil is on foot slopes and in drainageways. The Cascajo soil is on the short, steeper breaks. (In the <br />project area, the area east of the building at the base of the slope is Kim, and Cascajo soil is present on <br />Unit 72 <br />Name Midway-Cascajo complex, 10-40% slopes <br />Description <br />These soils are on moderately sloping to steep ridges, knobs, hills and edges of fan teraces that are <br />deeply dissected by streams. The native vegetation is mainly grasses, cactus, and scattered pinyon and <br />juniper. Clayey, montmorillonitic (calcareous), mesic, shallow Ustic Toriorthents and Sandy-skeletal, <br />mixed mesic Ustollic Calciorthids: both soils are non-hydric. <br />The unit is about 60 percent Midway soil and 20 percent Cascajo soil. The Midway soil is mainly on the <br />steeper side slopes. The Cascajo soil is mainly on knobes and hills and along the crests of terace <br />edges. Included with these soils in mapping are areas of Kim soils on teraces, tops of hills, and foot <br />slopes. Kim soils have a surface layer of loam. They make up about 10 percent of the unit. Also <br />included are small areas of shale outcrop on the steeper side slopes and some areas, making up about <br />10 percent of the unit, of soils that are similar to the Cascajo soil but are shallow or moderately deep to <br />shale bedrock. (In the project area, much of unit appears to be Cascajo and Kim soils, with less Midway <br />soils than the average for the unit.) <br />The Midway soil is shallow and well drained. It forned in residuum derived dominantly from shale. <br />Slopes range from 15 tc 40 percent. The surface layer is typically grayish brown very gravelly clay loam <br />about 3 inches thick. The upper 4 inches of the underlying material is clay. The lower part to a depth of <br />15 inches is extremely shaly clay. Weathered shale is at a depth of about 15 inches. The soil is mildly <br />alkaline to a depth of 7 inches and moderately alkaline below that depth. <br />Trans-Colorado Concrete October 99 <br />Application for Permit: Spotted Burro Pit Page 26 <br />
