~~ <br />E <br />SOIL CONSERVATION SERVICE 1919 Highway 50 West Pueblo, CO 81008 . <br />RECEIb'ED Jl1L 1 2 1985 <br /> <br />July 5, 1985 <br />Mr. James H. Kirkland <br />RBR Conatructian <br />P.0. Box 354 <br />Rye, CO 81069 <br />Dear Mr. Kirkland <br />This is in reference to the field investigation done an June 27, 1985 on a <br />proposed gravel pit located in SE 1/4 SE 1/4 s. 36 T20S R 64 W and in <br />NE 1/4 NE 1/4 s. 1 T 215 R 64 W. The following information may be used by <br />your company to fulfill the requirements of the Colorado Mined Land <br />Reclamation Board. <br />The proposed gravel pit has been located on the attached aerial photo copy <br />and soil survey map. The major soil is a Glenberg-Haverson fine sandy loam <br />(Gh). A soil description, along with engineering properties, are attached. <br />The site has had moat of the tree cover removed. Scattered trees of <br />cottonwood, Russian olive, and willow are present with their predominance <br />increasing toward the Arkansas River. The herbaceous layer is dominated by <br />kochia and inland saltgrass. Scattered patches of western wheatgrass, <br />galleta, and alkali sacaton can be found thoughout the area. A list of <br />the existing vegetation is attached. Specific vegetative cover estimates <br />are on the attached CO-ECS-2. <br /> <br />Based upon the Bite visit, your representative indicated that mining would <br />concentrate in the northwest corner of the permit area. The tree cover in <br />this area is OZ. The poet-mining land use is proposed as rangeland. You <br />should be aware that the water table may be encountered within several <br />feet from the surface. The reclamation plan is written far returning the <br />land to rangeland and does not address leaving the area as a pond. The <br />Soil Conservation Service recommends the following steps to stabilize <br />the site after mining: <br />1. Allow several h undrad feet of buffer area between any mining opera- <br />tioas and the canal within the site or the Arkansas River. <br />>:. <br />2. The top 6 inches of topsoil should be stockpiled prior to mining. <br />After mining is completed, the excavated area shall be graded to leave <br />slopes no steeper than 3:1. The land should be scarified 6 inches deep <br />following grading to provide better cohesion between topsoil and sub- <br />strate. The topsoil should be reapread across the area uniformly and <br />smoothly. <br />O <br />
