PURPOSE AND SCOPE OF STUDY This report presenu the resulu of a geotechnical stability study for the proposed Schmidt Property gravel pit located along Highway 6 & 24, east of Gypsum, Eagle County, Colorado. The project site is shown on Fig. 1. The purpose of the study was to assess the geologic and subsurface conditions and perform stability analyses for the final pit wall slopes. The study was conducted in accordance with our proposal for geotechnical engineering services to High Country Engineering dated November 14, 1997. A field exploration program consisting of a geologic reconnaissance and exploratory borings was conducted to obtain information on subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine their classification and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed for potential geologic impacu and to develop recommendations for final pit wall slope grading. This report summarizes the data obtained during this study and presents our conclusions, recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions identified. PROPOSED GRAVEL MINING The proposed gravel mining operation on the Schmidt Property will take place in six phases with mining starting in the western part of the property and moving to the east. At the completion of mining operations, the surface azea of the pit will cover about 121 acres and have an average depth of about 20 to 25 feet. The pit side slopes will be graded for reclamation to about 2: I (horizontal to vertical) or flatter. Each phase of mining will be reclaimed (after Phase I) to limit the area of disturbance to about 30 acres at one time. The excavation volume for the six phases will be about 3.9 million cubic yards. At the end of mining, the pit will have an east-west dimension of about 5,000 feet
