Boz 1220 <br />Carbondale, Colorado 81623 Job No. 197 682 <br />Subject: Slope Stability Evaluation Near Southern Property Line, Proposed <br />Gravel Pit, Schmidt Property, Highway 6 & 24, East of Gypsum, Eagle <br />County, Colorado <br />Dear Mr. Stephenson: <br />As requested by Steve Wujek of Knight Planning Services, we are responding to Item <br />A!4 of a letter by the Division of Minerals and Geology dated May 18, 1998, We <br />previously conducted a geotechnical study for the proposed gravel pit development and <br />presented our findings in a report dated December 11, 1997, Job No, 197 682. <br />The southern limit of [he gravel pit excavation is proposed to be about 50 feet from the <br />southern property line as shown on the design drawings by High Country Engineering, <br />dated November 19, 1997. Our analysis and design section of the gravel pit slope near <br />the southern property line are presented on Pigs. 6 and 7 of our previous report <br />(attached). Beyond the property line are the railroad track, telephone, fiber optic litres, <br />gas line and highway 6 & 24 at a distance of about 100 to over 200 feet. <br />Based on our analysis, the extent of potential failure of the temporary pit wall cut slope <br />will be well within the property limits and the 50 foot setback from the property line is <br />appropriate, In our opinion, there will be no sigtuticant damage to the utility lines, <br />railroad or highway due to the proposed grave] pit excavation. <br />If you have any questions or need further assistance, please call. <br />Sincerely, <br />HEPWORTH -PAWLAK GEOT ^°'`"CAL, INC. <br />`~ ~' ~~ T AF •y~ <br />o; <br />Steven L.
