MIGLIACCIO Engineering Geologist November 5, 1973 R & M No. 35138 Mr. Douglas Stark 957 Westbury Drive Anchorage, Alaska 99503 Re: Test Hole and Soil Log Report for Sanitary System, Tract 3 of Highland Terrace No.-'l~ Subdivision, Eagle River, Alaska Dear Mr. Stark: We are submitting herewith the test boring results and our comments regarding soil conditions encountered at the subject site. This investigation was performed in accordance with your request of October 12, 1973, and those procedures outlined in a letter dated September 13, 1971 by Mr. Rolf Strickland of the Great:er Anchorage Area Borough Department of Environmental Quality. A total of four test holes were put down within Tract 3 of Highland Terrace Subdivision for the purpose of defining general subsurface soil conditions for the proposed sanitary system. Excavation was accomplished with an auger type drilling rig and the test holes were extended to a total depth of 20.0 feet below ground surface. The final logs prepared for the test holes has been included in Drawing A-01. Ground water was not encountered in any of the test holes. Based on a visual examination of the road cuts bordering the south-west side of the property, it is our opinion that the soil and underlying material is essentially the same throughout the project area. Thickness of nhis material, however, may vary considerably as is indicated by the fractured bedrock exposed at shallow depths (less than 5 feet) in the road cut. Fractured bedrock is exposed by the road cut in the lower part of the middle lot and the over burden is shallow (less than 5 feet) in this area. We appreciate being given this opportunity to be of service to you. Should you have any questions with regard to the-above, please do not h~sitate to contact us. Very truly yours, R & M ENGINEERING & GEOLOGICAL CONSULTANTS James W.
