Box 774428 <br />Steamboat Springs, Colorado 80477 <br />Attention: Mr. Ed Fidler <br />Subject: Quarterly Inspection <br />Excess Spoil Disposal Area I <br />Eckman Park Facility <br />Job No. 9490A <br />Gentlemen: <br />As you requested, we inspected Excess Spoil Disposal Area I on August 2, <br />1983. The purpose of our inspection was to look for evidence of slope <br />instability and to determine if the spoil had been placed in general <br />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 Apri] 1983. The <br />benches and outslopes were topsoiled and seeded, Placement of rip-rap <br />rock in the diversion ditch to the south of the area was in progress. <br />We understand that final grading, topsoiling and seeding of the top of <br />the spoil pile 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 />[f we can be of further service in discussing the contents of this <br />letter or our observations, please call. <br />Very truly yours, <br />~, - <br />CTL /THOhPSON, INC. /~ ~ ' <br />Ronald M.
