NRCS made an on-site investigation on <br />October 16, 1994. <br />The proposed gravel pits are located on Agua Fria cobbly loam and <br />Dahlquist extremely stony loam. The Agua Fria cobbly loam can have <br />enough top soil in places to warrant stockpiling for future reclamation <br />activities. The Dahlquist extremely stony loam would not have adequate <br />amounts of topsoil to stockpile. <br />Present vegetation is representative of the loamy foothills and loamy <br />slopes range sites. Dominant plant species found on a reclaimed portion <br />of the gravel pit include smooth brome, orchardgrass, western wheatgrass <br />and mountain mahogany. <br />Slopes should be graded to a 3:1 slope where feasible. Where steeper <br />slopes are unavoidable, terraces should be constructed to trap and <br />control surface water flows, dispersing erosive energy of these flows to <br />minimize sheet and rill erosion and prevent gully erosion. Reclamation <br />should include seeding with adapted grass, forb and shrub species. The <br />NRCS can assist in developing seed mix's for this site if requested. <br />If you have any questions regarding these comments please feel free to <br />contact us. <br />Sincerely, <br />~~~,~~~~ <br />Fred Miller <br />SCD Chairman <br /> <br />
