Box 774428 <br />Steamboat Springs, Colorado 80477 <br />Attention: Mr. Mike Kondelis <br />Subject: Quarterly Inspection <br />Excess Spoil Disposal Area I <br />Eckman Park Facility <br />Job No. 9768A <br />Gentlemen: <br />As you requested, we inspected Excess Spoil Disposal Area I on October <br />18, 1983. The purpose of our inspection was to look for evidence of <br />slope instability and to determine if the spoil had been placed in <br />general conformance with the design. <br />There was no evidence of slope failures at the time of our inspection. <br />No spoil had been placed since our last inspection in August 1983. The <br />benches and outslopes were topsoiled and seeded. The top of the spoil <br />had been graded relatively level. We understand topsoiling and seeding <br />of the top will be started in the near future. <br />Based upon our inspections of Excess Spoil Disposal Area I, we believe <br />that this facility is being constructed in general conformance with the <br />design. The spoil appears to be stable. <br />If we can be of further service in discussing the contents of this <br />letter or our observations, please call. <br />~„~. <br />Very truly yours, <br />CTL/THOMPSON,~ /INC.
