SITE INVESTIGATION The site was investigated on August 12, 1987, and three percolation test holes were dug to a minimum depth of 30 inches. Holes were presoaked and percolation tests performed on August 13, 1987. Results of these tests are included in this report; see PERCOLATION TEST RESULTS. Also, a test pit was excavated to a depth of 7.5 feet on August 14, 1987, with a conventional backhoe. An investigation of the test pit was performed on August 17, 1987. A summary of the test pit log is also a part of this report; see Figure No. 1. Locations of the percolation test holes and the test pit are shown on Drawing No. 1. SITE LOCATION AND DESCRIPTION The site is located in a part of the East one-half of the Northwest one -quarter, Section 23, Township 5 South, Range 82 West of the Sixth Principal Meridian, Eagle County, Colorado, and is more particularly described on Drawing No. 2 of this report. 2 SITE LOCATION AND DESCRIPTION - continued The site is generally sloping to the southeast, and was covered with mature aspen trees. The cabin site has been cleared of trees, and a view corridor approximately 30 feet wide has been clear-cut to the southeast. SUBSURFACE AND GROUNDWATER CONDITIONS Subsurface conditions in the proposed leach field area are uniform, and consist of sand and gravel over weathered bedrock. Refer to Figure No. 1 for additional information. PERCOLATION TEST RESULTS A total of three percolation tests were performed on the site as specified by the Eagle County Individual Sewage Disposal System Regulations. Results were as follows: Test Hole Min/1" Drop Date of Test Ambient Air Temp. 1 9.2 8/13/87 65 2 7.5 8/13/87 65 3 8/6 8/13/87 65 Average time for 1 inch drop = 8.43 minutes DESIGN CRITERIA A log cabin has been proposed for this site for year-round use. The cabin will have a total of five (5) bedrooms, and 3 DESIGN CRITERIA - continued will not be equipped with a garbage disposer or automatic washing machine. Thus design criteria for calculations are: 2 persons/bedroom 75 gallons/person/day - average flow Maximum flow: 150% of average flow CALCULATIONS A = QY where A = minimum absorption area (sq.ft.) Q = maximum quantity of sewage flow (gal/day) T = percolation rate (min/inch) Q= 5 x 2 x 75 x 1.5 = 1,125 gal/day A = 11258.43 r= 653.3 square feet From Table 5 (Section 8.1 of the Eagle County Regulations), minimum absorption area for seepage beds is 215 square feet/ bedroom; therefore, 5 x 215 = 1,075 square feet of seepage bed required. From Table 4 (Section 7.1.a of the Eagle County Regulations), a 1500 gallon septic tank is required. SEPTIC SYSTEM RECOMMENDATIONS Based on the preceding calculations, it is recommended to install a 1500 gallon compartmented septic tank followed by a minimum 1075 square foot seepage bed. The seepage bed should lie a minimum of 10 feet from all property lines, 30 feet from the proposed cabin, and 100 feet from the existing well. 4 SEPTIC SYSTEM RECOMMENDATIONS - continued An inspection of the system should be made by a representative of the Eagle County Environmental Health Department prior to backfilling. The installation and material specifications must comply with the Eagle County Individual Sewage Disposal System Regulations. As an alternate to the standard 1,075 square foot seepage bed, 360 lineal feet of 10-inch diameter "gravel -less" leach bed tubing (as manufactured by American Drainage Systems, Inc.) could be embedded in the native soils of the site. Due to the remoteness of the site, this alternate would probably be cost effective. It is also recommended as options to either of the pre- ceding alternates to add a dosing chamber to the septic tank and an alternating valve to the seepage bed. The dosing chamber would allow for periodic high rate discharge to fill the drainage field instead of a slow trickle into the field. This would prolong the life of the drainage field. The alternating valve can also prolong the effective life of the drainage field by allowing an alternating flow of effluent to two separate halves of the drainage field. This allows the unused portion of the drainage field to rest and regenerate its opti- mum characteristics. 5 CONCLUSIONS This report has been prepared for the exclusive use of Ewing Trucking and Construction Company, for the specific application to the proposed "Trapper's Cabin" site at Beaver Creek, Eagle County, Colorado. The findings and recommendations of this report have been obtained in accordance with accepted professional engineering practices. There is no other warranty, either expressed or implied.

Box 7 Vail, Colorado 81658 Dear, Mr. Funk An inspection of the individual sewage disposal system for the "Trappers Cabin" on December 2, 1987 revealed that only half of the required Sb2 drainage pipe was installed. Ewing Trucking and Construction Company indicated that would like to install the rest of the drain field next spring. The system is equipped with a diversion valve that should be changed once each year, in the summer months. Since the diversion valve would not need to be changed until next summer, it will be appropriate to install the remaining Sb2 drainage pipe at that time. The system should function as installed this winter, however the remaining Sb2 pipe and connection to the other side of the diversion valve should be completed by July 1, 1988. A final inspection and approval will be granted at that time, if the system is installed according to the Inter -Mountain Engineering specifications. Please note the Engineer specified 360' of 10" Sb2 pipe, only two 90' lengths of pipe were installed If you have any questions regarding this letter please contact Erik Edeen of the Eagle County Environmental Health Office.
