Dept. of Natural Resources <br />This Report was developed by the Soil Cor-servation Service in reseonse to <br />your reouest for soils and revegetation information for the proposed gravel rit <br />located in N'w y. sec 31 R']6w' T2N (Granby,Colo.). <br />Soils: <br />See attached soils descriptions from Soil Survey of Grand County /,rea.Colo. <br />Existing Vegetation: <br />The proposed gravel Fit located on a hit. Loam/ Stony Loam SCS range site. <br />( see attached vegetation inventory formCO-ECS-2.) <br />Reclaimation Recommendations: <br />It is our understcnding t''^,at upon the completion of the gravel extraction <br />that the site will be reclaimed as non-irri€ated pasture. <br />Successful reclaimation of this area is derendent uron several factors other than <br />the actual seeding. Final slore grades should not er.ceed 2:1 in steeFness, with <br />3:1 or 4:1 being even better. In general, the chances of successful revegetat:cn . <br />increase as the percent slore decreases.mall areas with slores steecer than <br />3:1 are sometimes unavoidable but should be kett to a mimimum. <br />During gravel extraction any torsoil should be stockpiled for later use. <br />:,tockpiled torsoil should be seeded to an annual small Erain or to the enclosed <br />seeding; recommendation if the soil is to remain stockFiled for longer than one <br />growing season. Lpon completion of gravel extraction, torsoil should be spread <br />out over the areas to be reseeded to a Berth of at least 6 to 8 inches <br />Underlying material should be scarified before tocsoiling to rrovide a <br />good bond between substratum and the ±orsoil. ::ithout tor•soiling rev_eetet'_rn <br />success is unlikely. <br />:seedbed prenarctior. in rrobably the rrroct ir.portant factor determinir.~ the <br />success in establishing cermanent vegetative cover.
