Tltis land type consists of alluvium of variable materials and is very shallow over gravel and sand. These materials have a loamy sand or sandy loam surface layer. In many areas this layer is 5 to 20 percent gravel. Shale and sandstone outcrops are in some areas. Included in mapping are very small areas of a Vona loamy sand, a Vona sandy loam, and a Dacono loam, all good soils for farming. The surface layer varies in reaction from place to place and in places is calcareous. Slopes differ widely within short distances and range from 1 to 80 percent. Some aeeas are used for grazing, but the soils are too steep, too shallow, or too unstable for cultivation or good grass management. Muclt of this land type is rapidly being mined for sand and gravel, and thereafter is not usable for farming. The soils nornially have good bearing capacity for foundations, low shrink-swell properties, good natural drainage, and a low hazard of hydrolysis for buried metal pipe. Open ditches for transporting water are not suited because of rapid seepage. In some areas lawns and gardens would have to be built up, using better soil materials from other areas. In some areas, old gravel pits have been used as dump areas, then packed and filled with outside soil materials, and then developed for homesites. Capability unit VIIe-3, non-irrigated; Gravel Breaks range site; tree planting suitability group 4. VoB (Vona sandy loam), 1 to 3 percent slopes This soil has a profile similar to that described as representative for the series, but i[ has a sandy loam surface layer. The areas are extremely irregular in shape and range from 30 to 200 acres in size. The hazards of water erosion and soil blowing are moderate. Included in mapping, on small ridges and mounds on uplands, are small areas of Vona loamy sand. Also included, in irrigated areas, are some small areas of Dacono loam near terrace edges. Much of this soil is or has been cultivated. Some formerly irrigated areas have been or are being developed for industry and housing. In general, this soil is suitable for housing projects and has few limitations for construction. It is well suited to most irrigated and dry-farmed crops, but it is not so suitable for truck farming as the nearly level Vona sandy loam . It is excellent soil for active grass. Capability unit IIIe-4, irrigated, and Ive-5, non-irrigated; Sandy Plains range site; tree planting suitability group 2. Tnnnbe Pik Db1G f 12 Perini( Pnge 18 046
