C~ EXHIBIT 1-SOILS INFORMATION ~nks and Gesso, LLC The soils information provided below was obtained from the Soil Survey of Adams County, Colorado, published by the USDA Soil Conservation Service. The soils found onsite consist of Dacono Loam, Loamy Alluvial Sand, Nunn Loam, Terrace Escarpments, and Vona Sandy Loam. Generally, all of these soils are well drained and are commonly found on level terraces along the South Platte River. Dacono Loam This soil has 5 to 15 percent gravel in the surface layer and subsoil and it has a sand and gravel layer beiween 20 and 40 and inches. Runoff is slow and the hazard of water erosion is slight. The soil is easy to tilt and is well suited to almost all crops grown in the County. However, it is not well suited for very deep- rooted crops. Loamy Alluvial Land This soil occurs as small areas in major drainage ways. It is also a principal source of gravel. Nearly all areas are subject to flooding from streams. The soils are shallow and strat~ed. The strata are moderately textured material that is underlain by river sand and gravel. The soils of this land type absorb water at a rapid rate. The available water capacity is low, but many areas have a high water table that is beneficial to plant growth. Some of this land type is in native grass; the wetter areas produce sedges and cattails. This vegetation is largely sustained by the natural water table and by flooding. Nunn Loam This soil is on stream terraces in the County. Surface runoff is slow and the hazard of water erosion is slight. In a representative profile the surface layer is six inches thick and non~alcareous. The subsoil is grayishlbrown clay about 17 inches thick. Below a depth of 23 inches it is yellowish brown in color, and is calcareous and stratified to a depth of 40 inches. Terrace Escamments Terrace Escarpments occur as steep slopes of present streams. They also occur as steep faces of ten'ace that border the bottomlands and flood plains. This land type consists of alluvium of variable materials and is very shallow over the sand and gravel. These materials have a loamy sand layer which can be up to 20 percent gravel. Much of this land type is rapidly being mined for sand and gavel and thereafter not usable for farming. Terrace escarpments are too shallow, too gravelly, or too steep for cultivation. This soil is better suited for grassland.
