Bower <br />District Engineer <br />Colorado Division of Highways <br />P.O. Box 850 <br />Greeley, Colorado 80632 <br />RE: Application for Gravol Alining Permit near <br />Del Camino by Siegrist Construction Company <br />Dear Mr. Bower: <br />The letter dated A1arch 11, 1982 to the Alined Land Reclama- <br />tion written by D.H. Heiderstadt from your Denver office has <br />been referred to me. That letter prompted our meeting of today <br />at your office with Bob Cox of Siegrist Construction Co. and <br />Gary Johnson of your staff. <br />As a result of that disc>_lssion, we have arrived at a workable <br />program that should relieve those indicated concerns of the <br />Highway Department. Our program of mining in the vicinity <br />(generally less than 200') of the bridge structures over the <br />St. Vrain Creek on Interstate 25 and the service road will be <br />controlled so that no mining will occur during periods of flood <br />hazard, but instead mining will occur during late fall, winter, <br />and very early spring periods. At all times, the Creek banks will <br />be maintained in a safe and stable manner, with no excavation or <br />backfilling occuring at any time any closer to the stream than <br />that allowed by the Alined Land Reclamation conditions of-our <br />mining permit. <br />I trust that this letter recites the understanding of our <br />meeting today and provides adequate protective measures for your <br />facilities. I understand that you are prepared to contact Mined <br />Land Reclamation regarding our understanding. Should further <br />discussion be required, please contact me. <br />~nV1e(:~h k~~,. <br />,; .. <br />,,<c~: <br />n c.F • ~. <br />~,~ C: <br />r ~~ <br />i r:~ ~n, <br />~ ~`.. <br />LCN:jlp ~.~: <br />CC: Siegrist Co.
