Box 2418 <br />Grand Junction, CO 81$02 <br />This report was developed by the Soil Conservation Service in response to <br />your request for soils and vegetation information For the proposed gravel pit <br />located neat 32 Road and the old landing strip. S~SW~SEC35T15R.1E <br />Soils <br />Soils on the site are s:denti£ied by the Soil Survey of Mesa County as Black- <br />stone etorl\y loam 3 to 2596 elope and Avalon loam 0 to 396 slope. (See enclosed <br />soils descriptions). <br />Ezisting Vegetations <br />Existing vegetation on the site includes, but is not limited ta: <br />~ Grasses <br />Galleta <br />Forbes, Shrubs. & Trees <br />Yucca <br />Prickly pear cactus <br />Shadacale ealtbush <br />Mat ealtbuah <br />Ralogeton <br />ReclamatLon Recommendations: <br />Succesefl:l reclamation and revegetation of this area ie dependent upon sev- <br />eral factoe other than the actual seeding. Final slope grades should not exceed <br />2:1 in steepness, with 3:1 or 1•:1 slopes being even better, In general, the <br />chances of successful revegetation increases as the percent slope decreases.. <br />Small areas with elopes steeper than 3:1 are often unavoidable but should be <br />kept to a minimum. <br />During gravel extraction any topsoil should be striped and stockpiled £or <br />later use. This soil material should be spread our over the areas to be reseeded <br />to a depth of 6 to 6 inches. IInderlying material should be scarified to provide <br />a bond between substratum and the topsoil, It is realized that not .all areas <br />will be able to be topsoiled, however, as much area ae possible should be covered. <br />Without topsoiling, revegetation success in unlikely. <br />Seeding preparation ie probably the moat important factor deteTID]Slin$ the <br />/-, success in establishing permanent vegetative cover. Seed should be placed 4r' <br />to 1 inch deep in a friable but firm seedbed. All seed must be covered. Dril- <br />ling the seed ie preferred to broadcasting. <br />0 Tfte Soll Conservation Service SCS-AS-i <br />V is en aOencY of the 10-79 <br />DeOertmem of Aprit ullure <br />
