Subject: Lot 86, Sec. 33, T.12N., R.3W., S.M.
Dear Mr. Kimball:
In response to your request, we logged the test pits that
you excavated and performed percolation tests on Lot 86,
Sec. 33, T.12N., R.3W., S.M. The locations and the results
of these tests are presented on the attached standard
Municipality of Anchorage forms. The tests were performed by
our technician Mr. Roy McDonald.
The shallow soils appear layered with very permeable soils.
Underlying the layered shallow soils there exists a dense
silty sandy gravel, probably glacial in origin. Two percola-
tion tests were performed in the till with the results shown.
No free water was observed in' either excavation, however the
free water level may be expected to fluctuate Seasonally. No
bedrock was observed.
Mr. Kimball reported that the existing system on the property
has been operating satiSfactorily for ten years for the
present owners, and four years for previous owners.

The data indicates that conventional on-site sewer systems
can probably be developed on the~property. The stratification
of the soils is likely to be highly variable, so specific
system design should be based on the conditions observed in
the area of the absorption area, to maximize the use of the
shallow permeable soils, although rigorously designed systems
appear to be possible in the till.
We trust the foregoing is sufficient to your immediate needs.
Please call if you have any questions, or if we can be of
further service.
Very truly yours
Lam~,/~ . E.
