Erickson <br /> Division of Minerals and Geology <br /> Department of Natural Resources <br /> 1474 Main Avenue, Room 223 <br /> Durango, CO 81301 <br /> RE: Tesip_9rary Diversion and Treatment of Waters from Cement Creek <br /> l -19, Permit No'I-77-378 <br /> Dear Mr. Erickson: <br /> In response to your May 22, 1996 letter, I submit the following <br /> clarifications and additional information requested. <br /> Project Summary Corrections <br /> Your project summary is basically accurate with the following <br /> corrections. Some of these corrections result from the snow <br /> clearing allowing more accurate location of the pathway and <br /> adjustments for physical site conditions. <br /> o The pipeline length is approximately 600' with 350' - 400' <br /> being on previously undisturbed ground. <br /> o The grade of the pipe will probably be close to 2% ±. <br /> o In order to avoid numerous bends to follow contours it will be <br /> necessary to fill some low spots to grade. Fill is available <br /> from stockpiles created from the slope reduction project <br /> finished last fall on the Cement Creek bank. The remainder of <br /> the bench will be constructed as stated in your letter. <br /> Drainage will be installed as necessary in the fill zones. <br /> Additional Information Requested <br /> o Attached are a plan and section of the Cement Creek diversion <br /> that will give the general concept intended for installation. <br /> A 20" pipeline is shown on these although the actual <br /> installation may be 15" - 24" as previously stated depending <br /> on pipe availability, final adjusted slope, etc. <br />
