MILLER Profeealonel Engineer Chief Engineer Unwin, Scheben & Korynta 103 E. 26th Avenue Anchorage, Alaska 99503 Attention: Mr. Earl Korynta, P.E. Gentlemen: Soils Investigation Mountain Manor Subdivision Eagle River, Alaska This report presents the results of the soil investigation we performed for the proposed Mountain Manor Subdivision. Mountain Manor Subdivision consists of 61 acres located immediately south of Jamie Drive, about two miles east of the Eagle River business district. During our work we have consulted with Mr. Earl Korynta. The object of our investigation was to provide soils data for establishing the feasibility of disposal of sanitary wastes using seepage pits. Specifically our scope of work as outlined in our confirming proposal dated March 1, 1976, was to explore the soil conditions at the site by logging and sampling test borings, to perform laboratory tests on representative samples, and to provide a written, report describing the soil and ground water conditions. We also performed preliminary percolation tests to evaluate possible variations in percolation rates at the site. FIELD AND LABORATORY To investigate the soil conditions we drilled 27 borings during the period of February 27 through March 8, 1976. The borings were drilled using a six inch diameter flight auger to depths varying from five to 15 feet. During the drilling our engineer was present to log the materials encountered and obtain grab samples of the soil types encountered. The locations of the borings are indicated on the Boring Location Plan, Plate 1, and the logs of the borings are presented on Plates 2 through 15. The soils have been classified in accordance with the Unified Soil Classification System described on Plate 16. Unwin, Scheben & Korynta 5552,002.08 ADril 2, 1976 Page 2 HARDING-LAWSON ASSOCIATES In addition to the soil sampling, percolation tests were performed in four of the borinqs. The percolation tests were performed in accordance with the Drocedure outlined in the USPHS Manual of Septic-Tank Practice with water surface levels six to ten feet below ground surface. After completion of the field work the samples were reexamined in our laboratory to select representative sampies for testing. The laboratory testinq consisted of particle size analysis to confirm the soil classification. The results of the particle size analysis are presented on Plates 16 through 25, and are summarized on the boring logs. SITE AND SOIL CONDITIONS The site is a rectangle with dimensions of about 1300 by 2500 feet. Other than Jamie Drive which crosses the north edge of the property the site is undeveloped. Elevations vary from about 1100 feet above sea level in the northeast portion of the property to about 800 feet at the southeast corner. Most of the property has moderate slopes; of the total only about 10 acres have slopes in excess of 25 percent. Details of the topography and proposed development are shown on Plate 1. ' - The site is primarily underlain by granular soils with varying amounts of silt fines to the depths explored. The surface of the site is blanketed by forest duff (humus, leaves), and in a few locations is underlain by sandy and gravelly silt. Except for Borings 2-4 and 3-9 where the silt is eight-feet-deep, the surface silt is generally less than five feet deep. The granular soils that generally underlie 'the forest duff and also underli~ the silt, vary in class- ification from slightly silty sand and gravel to silty sand and gravel. No free water was encountered in the borings. To assist in the evaluation of the site we have zoned the property into three typical soil types which should have somewhat similar percolation characteristics. The soil zones are shown on Plate 1 along with the description of the soil types for each zone. CONCLUS IONS Based on the results of the field and laboratory work, we be- lieve that seepage pits are a feasible method of septic tank effluent disposal. The preliminary percolation tests indicate a wide varia- tion in percolation rates (from less than one inch per minute to more than 30 minutes per inch). To optimize the design of the seepage Unwin, Scheben & Korynta 5552,002.08 April 2, 1976 Page 3 HARDING -LAWSON ASSOCIATI;S pits we believe that percolation tests should be performed, on each lot after the roads have been graded and site access developed.
