<br />United States Soil <br />^epartment of Conservation <br />Agriculture Service <br />George Gregg General Manager <br />VALCO <br />PO Box 5?1 <br />Lamar, CO 81052 <br />Oear Mr. Gregg; <br /> <br />PO Bo>; 471 <br />Lamar, CO 81052 <br />Mtay 13, 1985 <br />~: ~,~~~ <br />On May 10,1985, John Bates and I inspected your stockpiles of <br />"topsoil" from the gravel pits north of Lamar. We found very <br />little evidence of erosion, since these stec4:piles are becoming <br />reestablished with Sand dropseed(Sporobolis cryptandrus), and <br />well protected with this grass along with annual weeds. At this <br />point, we feel that any attempt to flatten the slopes would <br />create more of an erasion hazard than it might solve. Therefore, <br />I would recommend that no disturbance be attempted at this time. <br />If you would like to sReed up the establishment of Sand dropseed, <br />you could broadcast 0.5 lb. PLS of seed per acre. I welld like <br />tv leave the seeding as a matter of your choice and not see it as <br />a requirement of any I;ind. <br />Where the river is trying to wash away some of this material, we <br />have no objection to the use of broken concrete as rip-rap, if it <br />is in large pieces and well placed. Native rvcl~. is generally <br />more attractive but creates a transportation problem, since there <br />is no large rack within the immediate vicinity. <br />If you have any further questions, please give us a cal' at <br />336-9058 or dray by the office, south of Lamar. <br />Si~n~ce~re~ly, <br />Robert L. Howland <br />pistrict Conservationist <br />
