i <br />• <br />(d) Plans jor topsoil segregation, preservation and replacement,' for stabilization, compaction and <br />grading of spoil; and for revegetation. <br />Topsoil <br />Topsoil shall be removed and segregated from other spoil. For reclamation, topsoil will be <br />replaced by a scraper and generally graded with a blade. All grading shall be done in a manner <br />that controls erosion and siltation of the affected lands, to protect azeas outside of the affected <br />land from slides and other damage. In addition, all backfilling and grading shall be completed as <br />soon as feasible after the mining process. <br />- ~f~ <br />Topsoil will be replaced on all azeas above the anticipated high water line. The minimum <br />thickness shall be 12 inches above the surrounding finished grade. The topsoil shall be keyed to <br />the underlying and surrounding material by the use of harrows, rollers or other equipment <br />suitable for the purpose. <br />Reveeetation <br />In an unaltered river system, periodic river flooding regenerates Cottonwood communities by <br />scouring the baze mineral soils and simultaneous prolonged high water level at the time of <br />Cottonwood seed dispersal. Aggregate will scarify baze mineral soil along the shoreline wetland <br />bench in late spring. This will help emulate the effects of flooding and stimulate the <br />establishment of native trees. This method has been studied by the Colorado Division of Wildlife <br />Reseazch Team and has been highly successful on other projects. <br />Please refer to Exhibit E -Reclamation Plan (e) for further details on revegetation. <br />AGGREGATE INDUSTRIES, INC. - MILLIKEN RESOURCE 112 PERMIT PAGE 17 <br />
