The top 6" to 24" (depending on <br />availability) of topsoil and/or overburden shall be stockpiled <br />and replaced in its original profile prior to revegetation. <br />Roadsides, Utilities, Cut/Fill Slopes - Replace the disturbed <br />soil as close to the original soil profile as possible prior to <br />revegetation. <br />The disturbed area ~ hat will be reseeded should have slopes that <br />are no greater tha,p,a 3 to 1 ratio (33a slope). <br />Activities that create considerable soil compaction (e.g. gravel <br />pits and roadsides), a ripping operation of 8 to 10 inches should <br />take place before replacing the top soil. The scarification <br />process on highly compacted soils provides at least two benefits. <br />Fracturing the soil allows for root penetration and forms pockets <br />for capturing moisture. <br />After the topsoil is replaced, a firm seedbed is required before <br />planting grass seed. A common cause of seeding failure is <br />inadequate seedbed preparation. The seedbed should be firm <br />enough to allow good seed-to-soil contact. A firm seedbed helps <br />Colorado State University, ILS.
