Home My WebLink About20000575 Banks and Gesso, LLC EXHIBIT I - SOILS INFORMATION Soils within the proposed permit area consist of only two soil types. The majority of the site (approximately 85%) contains the soil type termed Aquolls and Aquents, formed from alluvium. It is a deep, poorly drained soil type, which occurs on nearly level floodplains. The remainder of the site, in the northeast corner, contains the soil type Bankard sandy loam. This soil is a deep, well- drained sandy loam found on slopes of 3% or less and formed in alluvium on floodplains and bottomlands. Soil types mapped within the proposed permit boundary on the soils map contained within this Exhibit. The capability classification by the United States Department of Agriculture, Soil Conservation Service (SCS) and excerpts from the Soil Survey of Weld County (SCS, 1972), are contained in this Exhibit. The SCS capability classifications for the soils in the permit boundary indicate that the soils are suitable for use as reclamation topsoil for disturbed areas and that the soils have severe limitations for crop production unless careful management is practiced. 2000-0575 y1 i 4,23 Ft.Lupton Sand and Gravel Mine.CDMG.112 Permit 33 99024.WD L.G.Everist,Inc.
