Box 772129 <br />Steamboat Springs, Colorado 80471 <br />Attention: Mr. Mike Kondelis <br />Subject: Quarterly Inspection <br />Excess Spoil Disposal Area II <br />Eckman Park" Facility <br />Job No. 90178 <br />Gentlemen: <br />As you requested, we inspected Excess Spoil Disposal Area II on <br />April 14, 1983. The purpose of our inspection was to look for evidence <br />of slope instability and to determine if the spoil had been placed in <br />general conformance with the design. <br />At the time of our inspection, no excess spoil was being placed on <br />Spoil Area II. We understand that the Area 80 box cut has been <br />completed and that no further spoil will be placed on Spoil Area II. <br />The outslopes for this facility. appeared stable during our inspection. <br />The top of the spoil had been graded to direct runoff to the south, away <br />from the outslopes. We understand that final grading, topsoil placement <br />and seeding in this area may begin late this spring. <br />The results of our inspections to date indicate that Excess Spoil <br />Disposal Area II is being constructed in general conformance with the <br />design and is performing satisfactorily. <br />Please call if ~ can be of further service in discussing the <br />contents of this letter or our observations. <br />Very truly yours, <br />CTL/THOMP ON, INC. <br />8y ~ <br />Ronald M.
