rough tridens, slender buckwheat brush,plains blackfoot, 3-leaf sumac, mountain mahogany, <br /> • Indian ricegrass and one-seed juniper. <br /> 5. Reclamation Recommendations - Here are suggested operations toward the reclamation <br /> and revegetation of the site after completion of sand/gravel mining operations: <br /> ♦ Pre-Mining- Strip and stockpile all original topsoil for later replacement <br /> when revegetation work is to be done. <br /> ♦ Post Mining- 1) Smooth down all waste piles, hummocks and swales. <br /> Compact the fills to avoid further settling. Where possible finished grades <br /> should in general blend in with the surrounding topography. 2) Re-spread the <br /> stockpiled topsoil over the mined and disturbed areas. Apply at least 12" of <br /> topsoil (Note - soil surveys indicate at least 60"topsoil at pre-mining). <br /> ♦ Revegetation success can be further enhanced by construction of small <br /> depressions called "dozer basins". These are depressions usually made with a <br /> dozer or loader. They are generally about 15'x20' in size and 12"-15" deep <br /> with sloping side walls to permit grass drilling. Scattered over the reseeding <br /> area, these basins will catch and hold water for a few days and also provide <br /> snow melt storage. <br /> ♦ Revegetaion Seeding-A recommended grass seeding mixture is attached. <br /> These species, mostly natives,should be well suited for sandy loam soils in <br /> the foothill zone. Where seed is available, it would be advisable to also add <br /> native shrub species, see attached CO-ECS-5. <br /> • If this office can be of further assistance, feel free to contact us. <br /> Sincerely, <br /> Roy Roper <br /> Contract Soil Conservationist <br /> Attachments: Soils Map P w/ descriptions of soils <br /> Soil Survey, selected sections, as noted <br /> CO-ECS-5, Grass seeding planned <br /> • <br /> CONSERVATION—DEVELOPMENT—SELF-GGVEn?1,%IENT <br />
