Lounsbury & Associates 723 West Sixth Avenue ~ Anchorage, AK 99501 Re: 40 Acre parcel south of Rabbit Creek Road H.V.L. Job 976030 Dear Mr. Duke: At the request of Mr. Darl Kvasager of H. V. Lounsbury & Associates, we have completed a subsurface soils investi- gation on your property and transmitted herewith are the results of the test boring data. The purpose of the test borings was to determine the soil types, ground water and bedrock conditions which occur to a depth of 16 feet on this 40 acre parcel of land. A total of 8 test borings were drilled as shown on page 3 of this report. We spaced the test borings approximately 500 feet apart except for line C where deep snow and heavy tree growth forced us to drill tests borings where practical in this area. The test borings were drilled to a depth of 16 feet with a tracked mounted Mobile B-50 drill using con~ tinuous flight augers. Soil samples were generally obtained at 5 foot intervals. Laboratory analysis of the soil samples consisted of moisture contents and sieve analysis. The results of each of the test borings and lab tests are shown on pages through Discussion The typical soils encountered in this 40 acre tract consist of silty sands (SP/SM) and silty gravels (GP/GM). Drainage areas required for on-site sewage systems would generally range from 150 to 250 square feet per bedroom in these soils. No ground water or bedrock was encounterd to a depth of 16 ft. Page number ~ shows the plan review of the soil test borings performed. A profile view was not included with this report due to the irregular hilly terrain which requires a detailed $ 1 5 AUG 2 1976 David Duke 6/28/76 Page 2 topographic map. Subsurface soil conditions are also too complex to draw a general profile view. We feel tha~ the information provided with this report will suffice for a preliminary review. If we can be of further assistance or if you have any questions, please contact our office. Very truly yours, CONSTRUCTION TEST LAB / James D.
