The Allison site is <br />' currently native rangeland with a draw along the easC side. Plants presently <br /> growing include blue grama, western wheatgrass, green needle, red three awn, <br /> sun sedge and a few yucca. <br />' Please consider the following recommendations for reclamation <br /> . <br /> The Allison site is located south of Matheson on soil type Yoder-Truckton- <br />t Lismas complex, 3 to 15 percent slopes, map unit is Yt. Capability group is <br /> VIS - soils generally unsuitable for cultivation and limited for other uses <br /> by low moisture capacity, stones or other features. This is a Gravelly <br /> Outwash range site. Native plant community on this site consists of 85-900 <br />' grasses, 5$ forbs and 5-10$ shrubs. Vegetation is mainly cool and warm-season <br /> grasses. <br /> Topsoiling: The current topsoil should be removed and reserved to be used for <br /> reclamation. Topsoil should be spread uniformly over' the disturbed area to a <br /> packed depth of 6 inches. This should be 8" - 10" over exposed bedrock. In <br />' event that existing soils have insufficient depth, Copsoil shall be brought <br />in and spread over the deficient areas. <br /> Sita Preparation: Reclamation of the pit should be made by smoothing all <br /> banks to no more that 2:1 slopes and should be flatter where feasible and <br />t practicable. The topography should be made smooth with no spoil piles or pits <br /> present. <br />t Grass Seedinq: Area being reseeded should be treated as a critical area <br /> planting. When area is being reclaimed by broadcasting rather than drilled, <br /> the rates computed shall be doubled to meet seeding recommendations. The <br /> seedbed should be well settled and firm but friable for seed placement. Soils <br />' that have been over-compacted by equipment should b~ tilled to break up <br /> rooting restrictive layers, then harrowed, rolled or packed to prepare the <br /> required firm seedbed. Grasses should be drilled using a grass drill from <br /> November 1~t - April 30`h prior to a period of anticipated moisture and after <br /> all other treatment is completed. Recommended planting depth is 'h" to '/+". See <br /> the attached seeding recommendation (CO-eCS-S) for species amount and variety <br />' to use. <br /> The Natural Resources Conservation Service works hantl-in-hantl wim <br />' the American people to conserve natural resources an private lantls AN EQUAL OPPORTUNITY PROVIDER AND EMPLOYER <br />
