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. Rooney
