Subject: Soils investigation for sanitary sewer system; Lot 19, NW 1/4 of NW 1/4 of
Sec 21, T12N, R3W, SM, Anchorage, Alaska.
Dear Mr. Leonard:
At your request of July 8, 1978, I conducted a soils investigation at the proposed
location of a sanitary sewer system on the subject lot.
This investigation, which was accomplished on July 8, 1978, consisted of the
inspection of soils removed during digging of a test pit using a backhoe to a
total depth of 14.0 feet.
The topography of the area where the soils test was conducted, is generally sloping
in a west to northwest direction at approximately a 5-10% grade. Vegetation consists
of large spruce and birch, with alders, willows and devils club, including a low
ground cover of mosses and grasses.
The soils encountered are graphically shown on the accompanying test hole log. The
soils consisted of a layer of Organic silt with some Sand 1.5 feet thick overlying
a Silty Sand with a trace of Gravel and occasional Cobbles to a total depth of 14
feet.
No water table was encountered.
A percolation test was performed in a hand augered, 8 inch diameter, 26 inch deep
test hole, on a 3 foot deep bench dug by the backhoe at the side of the test pit.
An accompanying sheet graphically shows the location of the percolation test hole
and tabulates the results of the percolation test.
The accompanying sheet containing the test hole log, includes a sketch showing the
subject lot with the approximate locations of the test hole and the proposed house
in relation to the property lines.
I apreciate the opportunity to be of service to you. Please contact me if you have
any questions regarding this soils investigation.
Very truly yours,
~man~
