f. _ Transit Mix Concrete Co. EXHIBIT I SOILS INFORMATION Soil types were identified within the project area using existing United States Department of Agricultural' s Natural Resources Conservation Service (USDA NRCS) soil resources data. The NRCS has mapped eight soil map units (MU) on the property (NRCS 2015), as shown in Figure 1-1. The property occupies the rugged foothills of the Rocky Mountains, hilly terrain near the base of the foothills, and flatter, more gently sloping terrain where terraces and alluvial fans have formed below the foothills in the upper reaches of the piedmont. The mapped soils in the foothills (MU 77, Rock outcrop-Coldcreek-Tolman complex) are characterized by a high percentage of exposed bedrock and associated shallow soils. MU 77 is composed of rock outcrop, gravelly/cobbly sandy loam, or sandy clay loam soils, often with bedrock starting at 13 to 17 inches below the surface. Topsoil availability within this map unit is limited and ranges from 0 to 6 inches. The majority of the surface disturbance will occur within the MU 77 soil complex. Other soil complexes within the disturbance area occur within the haul road corridor. MU 76, the Rizozo-Neville complex, which is characterized by fine sandy loam and shallow loam soils, is associated with hilly terrain near the base of the foothills where they grade into the upper reaches of the piedmont. This soil type extends into the fans and terraces of the piedmont in some areas. Bedrock depths within MU 76 range from 20 to 60 inches below the surface. Topsoil availability ranges from 0 to 10 inches. The predominant soil types on the lower side slopes above the piedmont are MUs 57 and 58, and on the terraces and fans are MUs 12, 13, and 55. All five of these MUs are composed of deep, sandy loams. MU 57, Neville fine sandy loam, occurs on 3 to 9 percent slopes and depth to bedrock is estimated at 60 inches below surface with 0 to 10 inches of topsoil available. MU 58, the Neville-Rednum complex also occurs on 3 to 9 percent slopes. Bedrock depths range from 60 inches below the surface with 0 to 10 inches of available topsoil. MU 12, Bresser sandy loam, occurs within 3 to 5 percent slopes. Bedrock depths are at 60 inches below surface with 0 to 8 inches of available topsoil. MU 13, Bresser sandy loam, occurs within 5 to 9 percent slopes. Bedrock depths are at 60 inches below surface with 0 to 8 inches of available topsoil. MU 55, Nederland cobbly sandy loam, occurs within 9 to 25 percent slopes. Bedrock depths are at 60 inches below surface with 0 to 5 inches of available topsoil. These soils predominately are deep, sandy loam soils associated with the lower side slopes, terraces and fans of the piedmont. Hitch Rack Ranch Quarry Permit Application M-2016-010 July 14, 2016 1_2
