1F, _ & <br /> Transit Mix Concrete Co. <br /> EXHIBIT I <br /> SOILS INFORMATION <br /> Soil types were identified within the project area using existing United States Department of <br /> Agricultural' s Natural Resources Conservation Service (NRCS) soil resources data. The NRCS <br /> has mapped eight soil map units (MU) on the property (NRCS 2015), as shown in Figure 1-1. The <br /> property occupies the rugged foothills of the Rocky Mountains, hilly terrain near the base of the <br /> foothills, and flatter, more gently sloping terrain where terraces and alluvial fans have formed <br /> below the foothills in the upper reaches of the piedmont. <br /> The mapped soils in the foothills (MU 77, Rock outcrop-Coldcreek-Tolman complex) are <br /> characterized by a high percentage of exposed bedrock and associated shallow soils. MU 77 is <br /> composed of rock outcrop, gravelly/cobbly sandy loam, or sandy clay loam soils, often with <br /> bedrock starting at 13 to 17 inches below the surface. Topsoil availability within this map unit is <br /> limited and ranges from 0 to 6 inches. The majority of the surface disturbance will occur within <br /> the MU 77 soil complex. <br /> Other soil complexes within the affected lands area occur within the haul road corridor. MU 76, <br /> the Rizozo-Neville complex, which is characterized by fine sandy loam and shallow loam soils, is <br /> associated with hilly terrain near the base of the foothills where they grade into the upper reaches <br /> of the piedmont. This soil type extends into the fans and terraces of the piedmont in some areas. <br /> Bedrock depths within MU 76 range from 20 to 60 inches below the surface. Topsoil availability <br /> ranges from 0 to 10 inches. <br /> The predominant soil types on the lower side slopes above the piedmont are MUs 57 and 58, and <br /> on the terraces and fans are MUs 12, 13, and 55. All five of these MUs are composed of deep, <br /> sandy loams. <br /> MU 57, Neville fine sandy loam, occurs on 3 to 9 percent slopes and depth to bedrock is estimated <br /> at 60 inches below surface with 0 to 10 inches of topsoil available. <br /> MU 58, the Neville-Rednum complex also occurs on 3 to 9 percent slopes. Bedrock depths range <br /> from 60 inches below the surface with 0 to 10 inches of available topsoil. <br /> MU 12, Bresser sandy loam, occurs within 3 to 5 percent slopes. Bedrock depths are at 60 inches <br /> below surface with 0 to 8 inches of available topsoil. <br /> MU 13, Bresser sandy loam, occurs within 5 to 9 percent slopes. Bedrock depths are at 60 inches <br /> below surface with 0 to 8 inches of available topsoil. <br /> MU 55, Nederland cobbly sandy loam, occurs within 9 to 25 percent slopes. Bedrock depths are <br /> at 60 inches below surface with 0 to 5 inches of available topsoil. <br /> These soils predominately are deep, sandy loam soils associated with the lower side slopes, <br /> terraces and fans of the piedmont. <br /> Hitch Rack Ranch Quarry Permit Application <br /> October 3, 2017 1-2 <br />
