Nelson <br />Nelson Engineers <br />Greeley National Plaza <br />822 - 7th Street <br />Greeley, CO 80631 <br />Re: Reclamation Plan for Siegrist Companies <br />Dear Lavern: <br />Soils information for Planned Permit Area: <br />Map Symbol 3 - Aquolls and Aquents, gravelly substratum. , <br />15 - Colby loam, 1 to 3 percent slopes. <br />61 - Tassel fine sandy loam, 5 to 20 percent slopes <br />(See attachment for detailed description of soils and location of <br />soils on site) <br />The area along the northern margin of the area (steeply sloping) is <br />Tassel fine sandy loam. This area should not be mined because of the <br />difficulty of establishing vegetation on disturbed areas that have this <br />type of slope. The small area of Colby loam is considered a prime farm <br />soil. Apparently the majority of the mining will take place on the area <br />of Aquolls and Aquents. <br />Top soil should be stock piled as it is removed from the mining site. <br />This stock pile should be reseeded to Russian wild rye (5# PLS/Ac), and <br />sweet clover (3.5# PLS/Ac). This will help lessen erosion on the stock <br />pile. Side slopes will be cut at a grade that will allow placement of <br />topsoil. Slope of 2:1 or flatter will be used. <br />Top soil will be reapplied to slopes and berms after pits are filled with <br />water to maximize re vegetation efforts. The above seeding mix and rates <br />will be used after application of top soils to disturbed areas. A temporary <br />cover will be planted if planting of permanent cover is to be delayed. <br />Trees and shrubs that are adaptable to the area will be planted after closure <br />of each pit to increase aesthetic value and provide wildlife cover around <br />completed ponds. <br />0 <br />
