Parkdale Proiect ~ 3 • Reclamation Permit <br />1.8 Shanta loam, 0 to 3 percent slopes <br />Well drained soils forming on stream retraces in alluvial parent materials are <br />characteristic of this unit. This unit is not scheduled for disturbance. The Shanta loam <br />makes up approximately 85 percent of the unit. Representative textures for this soil <br />series include loam surface and upper subsoil horizons over stratified sandy loam and <br />loamy 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 percent throughout <br />the profile. The effective rooting depth is 60 inches or more. This soil is non-saline and <br />non-sodic. The hazard of water erosion is slight. <br />1.9 Ustic Torriorthents, bouldery-Rock outcrop complex, 35 to 90 percent slopes <br />This map unit occurs on mountainsides near the eastern border of the permit area and is <br />not proposed to be disturbed. The Ustic Torriorthents typically make up 55 percent of <br />the unit while the rock outcrop portion overlies 30 percent of the unit. These <br />components are intermingled on the side slopes. The Ustic Torriorthents are typically <br />very shallow to moderately deep, well to excessively drained soils forming in residuum <br />and colluvium from gneiss and granite parent materials. These soils are characterized by <br />very gravelly loam and gravelly clay loam textures, varying effervescence, and neutral to <br />moderate alkalinity. The coarse fragment content ranges from 25 to 40 percent <br />throughout the profile. The effective rooting depth is 4 to 30 inches or more. This soil is <br />non-saline and non-sodic. The hazard of water erosion is high to very high. <br />
