:OILS DESCRIPTION <br /> ADAMS COUNTY, COLORADO <br /> TERRACE ESCARPMENTS (Tc) occur as breaks or steep side slopes adjacent <br /> to the channels of present or farmer streams. They also occur as `.he <br /> steep faces of terraces that border bottomlands and flood plains. <br /> This land type consists of alluvium of variable materials and is <br /> very shallow over gravel and sand. These materials have a loamy sand <br /> or sandy loam surface layer. In many areas this layer is 50 to 20 <br /> percent gravel . Shale and sandstone outcrops are in some areas. <br /> Included in mapping are very small areas of a Vona loamy sand, a Vona <br /> sandy loam, and' a Dacono loam, all good soils for farming. <br /> The surface layer varies in reaction from place to place and in <br /> places is calcareous. Slopes differ widely within short distances and <br /> range from 1 to 80 per cent . Some areas are used for grazing , but the <br /> soils are too steep , too shallow, or too unstable for cultivation or <br /> goad grass management . <br /> Much of this land type is rapidly being mined for sand and <br /> gravel , and thereafter is not usable for farming. Such areas are used <br /> as a dumping ground or are back filled with better soil material in <br /> places . Many areas of this land type are well suited to housing or <br /> industrial developments or highway location. Prior to use for these <br /> purposes , however , the stability of the soils should be determined <br /> because of slope or lack of binder soil particles. The soils normally <br /> have good bearing capacity for 7oundations , low shrink-swell <br /> prop=rties , -cod natural drainage and a low hazard of hydrolysis for <br /> buried metal pipe . Open ditches for transporting 'cater are not suited <br /> because oI . aple seepage . <br /> In some areas _awns and gardan would have to be built up , using <br /> better soil materials from other areas. In some areas , old ravel <br /> pits have been used as dump areas , then packed and filled with outside <br /> soil materials , and then , developed for homesites .
