Banks and Gesso, LLC <br />western wheatgrass. Also predominate are saltgrass, sedge, rush and alkali bluegrass <br />(USDA, SCS). <br />Bankard sandy loam (indicated as "10" on Exhibit I-1) is also found in the western <br />portion of the site. This soil has 0- to 3- percent slopes and is deep and excessively <br />drained. It is formed in stratified recent alluvium along streams and rivers. The surface <br />layer is typically brown sandy loam approximately 4 inches thick. Underlying this is pale <br />brown calcareous sand stratified with thin lenses of sandy loam, loam and fine gravel to <br />an approximate depth of 60 inches. Permeability is moderately rapid and available <br />water capacity is low. Additionally, surface runoff and erosion hazard are low. Effective <br />rooting depth is approximately 60 inches plus. Bankard soils are suited to limited <br />cropping. It is also sandy and subject to flooding. Pasture is the best use for this soil. <br />Some of the most suitable crops include tall wheatgrass, tall fescue and annual <br />sweetclover. This soil is not suited to urban or recreational development as a result of <br />the flood hazard (USDA, SCS). <br />Dacono clay loam (indicated as "21" on Exhibit I-1) makes up the northeastern portion of <br />the site. This soil has 0- to 1-percent slopes and is deep and well drained. It is formed <br />in mixed alluvium. The surface layer of Dacono soils is typically grayish brown clay loam <br />approximately 12-inches thick. The subsoil is approximately 15-inches thick and <br />consists of grayish brown clay loam. Permeability is moderately slow and available <br />water capacity is moderate. Effective rooting depth is approximately 20 to 40 inches. <br />Additionally, for Dacono soils, surface runoff is slow and erosion hazard is low. Dacono <br />soils are used almost exclusively for irrigated crops and are well suited to corn, sugar <br />beets, beans, alfalfa, small grain, potatoes and onions (commonly grown crops for the <br />area). It has fair potential for urban and recreational development, with moderate to high <br />shrink swell, low strength and moderately slow permeability of the soil, above the sand <br />and gravel substratum, being the limiting features (USDA, SCS). <br />Heit Sand and Gravel Mine <br />SW Meadow, LLC <br />02044 <br />February 2003 <br />18 <br />
