6. Soils <br />The Paonia Area SCS Soils Survey Sheet 16 shows that the area for this 1 l0 permit consists of two <br />soil types, which are listed below. The approximate soil boundaries are shown on Map Exhibit B-1. <br />35 - Fluvaquents, flooded, on floodplains and low terraces, 0 to 8 percent slopes. <br />42 - Glenton Fine Sandy Loam, on floodplains and low terraces, 0 to 3 percent slopes <br />It is necessary to point out that the site was graded many yeazs ago for irrigation, so that the original <br />soils were disturbed and in some places, removed. It is expected that the average topsoil thickness <br />that can be stripped from the site is 4 inches. This includes the fact that none will be stripped from <br />the existing small pond that is part of the mining area as well as a portion of the site which was pre- <br />viously dozed, which has gravel immediately on the surface. Below the topsoil is a layer (< 3 feet) of <br />subsoil/overburden exists before the gravel deposit is reached. As described in the mining plan, all <br />topsoil will be salvaged and used in reclamation. Since much more topsoil will be stripped than is <br />needed to reclaim the slopes of the lake and the small azea above the lake, the stripped soil will be <br />used to increase the thickness of the replaced topsoil. <br />7. Vegetation <br />No native vegetation communities are currently present within the proposed permit area. As de- <br />scribed in the section on land use, the site was dozed to facilitate irrigation decades ago. The field <br />has been irrigated for hay production since that time. Production has been approximately 2.5-3.0 <br />tons per acre per year. Some thistle and other weeds aze present in field but make up less than 5% of <br />the total vegetation. The depression shown on Map B-1 has allowed more water to accumulate, thus <br />creating a man made wetland in the bottom, consisting of cattials, and willows. The central portion <br />of the mining area also contains some willows and some immature cottonwoods as a result of past <br />North Fork Pit Mazch 04 <br />
