Elevations were provided by Basin Resources based <br />upon altimeter readings. Our observations and the test results indicate compaction <br />generally exceeds 90 percent of maximum standard Proctor dry density (ASTM D 698). <br />The wet areas noted at the New Elk RDA during our last visit (September 21, 1995) were <br />• not present and the surface had been leveled and compacted according to our <br />recommendations. <br />Groundwater measurements will be performed during our next visit. If you have <br />questions, please call. <br />Very truly yours, <br />CTL/THOMPSON, INC. <br />Mark G. Gray, P.E. <br />Project Manager <br />Reviewed by: <br />Ronald M.
