Ezhiblt 1 CMLRB 112 Permit Application <br />Agile Stone Systems, Inc. <br />Sedillo cobbly sandy loam, 4 to 25% slopes <br />This map unit consists of well drained soils forming on fan terraces in calcareous, <br />gravelly and cobbly alluvium along the Arkansas River. The unit may be disturbed by <br />rail spur construction. The Sedillo soil, making up about 85% of the unit, is typically <br />characterized by extremely cobbly and stony looms and sandy clay looms over looms to a <br />depth of 60". This soil is neutral to moderately alkaline, non- to strongly effervescent, <br />and has a coazse fragment content ranging from 5 to 75% throughout the profile, <br />decreasing with depth. The effective rooting depth is 60" or more. This soil is non-saline <br />and non-sodic. The hazard of water erosion is slight to very high. <br />Shanta loam, 0 to 3% slopes <br />Well drained soils forming on stream terraces in alluvial pazent materials are <br />chazacteristic of this unit. This unit is not scheduled for disturbance. The Shanta loam <br />makes up approximately 85% of the unit. Representative textures for this soil series <br />include loam surface and upper subsoil horizons over stratified sandy loam and loamy <br />sand lower subsoil textures. This soil is mildly to moderately alkaline, slightly to <br />strongly effervescent and has a coarse fragment content less than 15% throughout the <br />profile. The effective rooting depth is 60" or more. This soil is non-saline and non- <br />sodic. The hazard of water erosion is slight. <br />Ustic Torriorthents, bouldery-Rock outcrop complex, 35 to 90% slopes <br />This map unit occurs on mountainsides near the eastern border of the permit azea and is <br />• not proposed to be disturbed. The Ustic Torriorthents typically make up 55% of the unit <br />while the rock outcrop portion overlies 30% of the unit. These components are <br />intermingled on the side slopes. The Ustic Torriorthents aze typically very shallow to <br />moderately deep, well to excessively drained soils forming in residuum and colluvium <br />from gneiss and granite pazent materials. These soils are characterized by very gravelly <br />loam and gravelly clay loam textures, varying effervescence, and neutral to moderate <br />alkalinity. The coazse fragment content ranges from 25 to 40% throughout the profile. <br />The effective rooting depth is 4 to 30" or more. This soil is non-saline and non-sodic. <br />The hazard of water erosion is high to very high. <br />2.0 Field Investigations <br />• <br />The SCS survey completed for portions of Fremont County was reviewed by Cedar <br />Creek Associates 4/97 to become familiar with the general edaphic characteristics of the <br />project area. In addition to the review of existing soils information, project maps were <br />evaluated to locate dominant features of the project azea and probable access routes to <br />and from the acreage to be evaluated. <br />Following the review of existing information, field studies were completed by Cedar <br />Creek (4/97) and Azurite, Inc. (11/97). The proposed project area was traversed to <br />become familiar with access routes and surficial soil conditions chazacteristic of the site <br />as influenced by topography, vegetation, and geology. Observations were also made with <br />respect to soil salvage potentials as expressed through topography and vegetation cover. <br />3 <br />
