carbonate equivalent within 40 inches, typically, does not exceed 10 percent. The soil has a <br />slightly sodic horizon within 30 inches of the soil surface. <br />Morapos Loam, 12 to 25 percent slopes <br />The Morapos component occupies a small portion of the permit area. Slopes are 12 to 25 percent. <br />This component is located on hills and structural benches. The parent material consists of eolian <br />deposits and/or slope alluvium over residuum weathered from shale. Depth to a root restrictive <br />layer is greater than 60 inches. The natural drainage class is well drained. Water movement in the <br />most restrictive layer is moderately low or moderately high. Available water to a depth of 9.2 <br />inches is high. The frequency of flooding and ponding is zero. This component is in the <br />R034XY292CO Deep Loam ecological site. Nonirrigated land capability classification is 6e. <br />Soils in this class have severe limitations that make them generally unsuitable to cultivation and <br />limit their use largely to pasture or range, woodland, or wildlife food and cover. Also this soil <br />made up of soils where the susceptibility to erosion is the dominant problem or hazard in their <br />use. Erosion susceptibility and past erosion damage are the major soil factors for placing soils in <br />this subclass. The calcium carbonate equivalent within 40 inches, typically, does not exceed 15 <br />percent. <br />Shermap loam, 3 to 12 percent slopes <br />The Shermap component occupies a small portion of the permit area. Slopes are 3 to 12 percent. <br />This component is on hills and structural benches. The parent material consists of eolian deposits <br />derived from sandstone and shale and/or slope alluvium derived from sandstone. Depth to a root <br />restrictive layer is greater than 65 inches. The natural drainage class is well drained. Water <br />movement in the most restrictive layer is moderately high. Available water to a depth of 9.8 <br />inches is high. The frequency of flooding and ponding is zero. This component is in the <br />R048AY228CO Mountain Loam ecological site. Nonirrigated land capability classification is 6e. <br />Soils in this class have severe limitations that make them generally unsuitable to cultivation and <br />limit their use largely to pasture or range, woodland, or wildlife food and cover. Also this soil <br />made up of soils where the susceptibility to erosion is the dominant problem or hazard in their <br />use. Erosion susceptibility and past erosion damage are the major soil factors for placing soils in <br />this subclass. The calcium carbonate equivalent is zero percent. <br />Hayden Gravel Pit, May 2013 I -2 <br />
