Dear Fred,
In response to your request we have performed soils investiga-
tions on the referenced project. The sole purpose of these
investigations was to provide data with which the Municipality
of Anchorage Department of Health can evaluate the property
with respect to its suitability for subdivision. To this end,
six test pits were dug on the property, two on 8/23/80; two
on 9/6/80 with a JD 510 backhoe, and two on 9/20/80 with a
Case backhoe. The JD 510 backhoe was subcontracted from RCJ
Enterprises. The Case backhoe was provided by the developer.
In areas where the free water level allowed, percolation tests
were performed in the layers apparently most suitable to
develop waste water disposal systems. The approximate loca-
tions of the test pits are shown on the attached sketch. Ail
deep test pits were backfilled after excavation with a
perforated pipe placed full depth in the pit to monitor the
stabilized seasonal free water level. The shallow pits in
which the percolation tests were performed were left open.
Either Mr. Roy McDonald or Mr. William E. Palmer, C.E.T., of
our staff was on-site to log the test pits and perform the
percolation tests. The results are attached. The soils
classifications are visual without laboratory verification.

Dear Les:
907-276-4113
1980
This letter confirms our conversation regarding Wildberry Estates
Subdivision. Originally, four 1~ acre lots were contemplated for
the five-acre parcel. However, the western one-quarter of the
property appears too wet to develop on-site sewer systems so the
parcel was resubmitted as 2-2~ acre tracts. As described in our ~
letter of October 7, 1980, there were three efforts to provide.
soils information.
The last effort was with an owner-supplied backhoe and resulted in
test holes only 10 feet deep. However, this attempt was solely to
provide data with respect to shallow system installation due to the
high density of the deeper soils and shallow perched water levels.-~
The data indicates that shallow perched water levels existed in
test holes 3 and 4 dUring excavation. However, 4" perforated pipe
was placed to depth in each location. The free water level was
observed @ 11'-5" in TH3 5 days after digging, and TH4 was observed
to be dr~y to 12~'~ 5 day~ after digging.
~The data indicates that shallow water levels will affect areas of
kthe property, but in the 2~ acres availabl'e for development, it
}appears that a shallow sewer system could be installed in the area
Jdefined by test hole 5 which would intercept the shallow permeable
soil. Percolation tests were run from 2.75' to 4.~5~ and from 4.0
to 5.5 feet in this area with percolation rates o{~inutes per
/ inch.
A trench 6~feet deep and 2~ feet wide with
result in a trench length of approximately
.house. ~,0'
3 feet of gravel would
90 feet for a 4 bedroom

In our opinion, it will be necessary to verify continuity of condi-
tions before or during installation of the.system and verify that
shallow perched water levels do not harm the system. However, it
appears from the data that on-site sewer s%s~m-~evelopment will be
possible if carefully approached on the/~ast half~ ~f the western
2~ acre lot ~ ~./'
