~~ .. Gravel Pit Reclamation Plan Sec 22, T 145, RSOW ~I I I I~ ~ I~ I ~~ ~I~~ ~II ass The existing gravel pit is located in the Stoneham loam, 0 to 3 percent elopes, mapping unit. A soils map and mapping unit descriptions are attached, Vegetation on the site consists of native grasses, forbs, brush and trees. Native grasses include blue grams, buffalograsa, bottlebrush aquirreltail, three awn, sand dropaeed, western wheatgrass and inland saltgrasa. Other plants found include sand sagebrush, prickly pear, rubber rabbitbrush, yucca, snekeweed and cottonwood trees, A drainageway is located immediately to the east of the pit. It appears that a sediment retention structure has been constructed to prevent sediment damage to downstream areas, Adequacy of the structure ie questionable. Construction Topsoil should be stockpiled during mining operations and later reapplied after alopea have been shaped to aid in re~establiahing vegetation. Following mining operations, alopea should be shaped to 3:1 or flatter, Small areas of 2:1 alopea are often unavoidable but should be kept to a minimum, Runoff water frocs the site or adjacent areas must be controlled with diversions or similar structures to prevent serious erosion and damage to the planting, Fertilizer Requirements The rate of fertilizer application should be 50 pounds of nitrogen (N) and 50 pounds of phosphate (P205) per acre. Time of application shall be immedi- ately prior to seeding, at the time of seeding, or immediately following seed- ing, as applicable to the kind of fertilizer and type of equipment used, Seedbed Preoara[ion.and Seeding The seedbed should be well settled and firm. Competitive stands of weeds should be controlled with shallow tillage or by application of herbicides. Soils that have been over-compacted by equipment, especially when wet, should be tilled to break up restricting layers, Seed should be planted with a grass drill. Small areas too steep for drilling may be broadcast by hand, Seed planted with a drill shall be covered with soil to a depth of 1/4 to 3/4 inch, Broadcast seed may be incorporated by raking or harrowing. The following seed mixure is suitable.
