Alamosa, CO 81101 <br />Dear Mr. Ungefug: <br /> <br />.„ <br />~~1' <br />Attached is the soils map and descriptions of the soils present at the King Pit <br />gravel oE~eration. As you can notice, the MtD map unit is a complex of Mount Home <br />and Saguache Soils. Both have very limited topsoil, but approximately 6" to 12" <br />should be removed and stockpiled. Stockpiled topsoil should be seeded to prevent <br />wind and water erosion and encroachment of weeds. (See attached seeding plan.) <br />When mining operations are concluded for a portion of the area no slopes should <br />exceed 3:1 south and west facing slopes should be 4:1 or even flatter. Natural <br />drainage ways should be returned to pre-mining conditions as much as possible. <br />Since topsoil will be very limited, the mined area should first be covered with <br />approximately 6" of the natural fines (minus II 4 sieve material on site) as a soil <br />building medium. Topsoil should then be spread. A chiseling operation is recommended <br />to pa`i•tiaYly mix subsoil, natural fines, and topsoil. „eSigce excessive cobble exists <br />natuca~ly in the topsoil, it will have to be rock raked' before drilling, or seed <br />will have to be broadcast. The attached seeding plan uses the broadcast option. <br />These species and varieties should come as closely as possible to restoring the <br />site to original conditions (See Range Inventory Sheet attached.) <br />If you ha•oe questions on these recommendations please let me know. <br />Richard T..
