Permit applicant has the responsibility to inform this department during the
installation inspections of any wells adjacent to this property and the number
of residences that the well will serve.
* * * TWO(2) INSPECTIONS ARE REQUIRED * * *
Backfilling of any system without final inspection and approval by this departmeni
will be subject to prosecution.
Minimum distance between a well and any on-site sewage disposal system is 100 feet
for a private well or 150 to 200 feet from a public well depending upon the type
of public well. Minimum distance from a private well to a private sewer line
is 25 feet and to a community sewer line is 75 feet. Well logs are required
and must be returned to this department within 30 days of the well completion.
Other requirements may apply. Specifications and construction diagrams are
available to insure proper installation.

Subject: Tract A, Pollock Subd.
Dear Ms. Kovacs,
As directed by Mr. John Lynn of the Municipality ~f Anchorage
Department o£ Environmental Quality (D.E.Q.) in his letter of September
22~ 1978~ we monitored the water levels in the standpipes that we
placed in the test borings which ~e performed on your property in
September ~978. These observations are summarized on the attached
~late.
~ As you recall, you and I discussed these results '.vith ~f
Stricklan~L-~t~--~. in May of ~979. At this time
h~--~ s
that department would recommend against subdivisitn of the property
until subsurface drainage of the property lowers the apparent £ree
water level sufficiently to acce~t conventional on site se',',er systems./
He indicated, however, that a permit could be
~e$idence~ if a~..e~perimental mound type soil absorption system wa~
~sed_~. It was understood that should this system fail, a holding tank
~ould be necessary and he further indicated that the D.E.Q. would
issue that permit~ if required.
As you recall, we discussed some of your options regarding this
property. In ~ur opinion, these options include but are not limited
to:
~.) Maintaining the tract as one parcel and developing an
experimental mound type waste ~ater disposal system for a single
residence, assuming that should the system fail; a holding tank
could be installed.
2.) Demonstrating that subsurface drainage can sufficiently
lower the apparent subsurface water levels to allow installation of
Kovacs 6/6/79
page two
of conventional sewer systems, bearing in mind that sufficient senera-
tion between the drainage system and the sewer system will be required
to prevent c~ntamination of the water discharged from the drainage
system, and that some attempts by others at subsurface drainage in
the area have not been successful.
3.) Holding the property undeveloped until the public sewer
system is extended into this area. With the proper siting of improve-
ments, options 1 & 5 could be combined and still maximize the total
number of future lots.
As you recall, we also discussed with Mr. Strickland, zero
discharge grey and black water systems currently being developed.
These systems may not presently be cost effective for this application.
As we discussed, I could provide a preliminary cost estimate and
preliminary design of the drainage system if you desire, as well as
a design for the mound type waste water disposal system However,
I cannot accurately evaluate the market to determine the increase in
value of the property resulting from each of the development options.
It is my understanding that you presently intend to market the property,
as is, and that further service from this soils engineer is not
required. We trust that this letter is comprehensive of our discussion
with Mr. Roll Strickland. Please feel free to call should questions
arise or if we can be of any further service.
Very Truly Yours,

Dear Ms. Kovacs,
At your request, one test boring was placed on each of the four
lots in the proposed subdivision of Tract A, Pollock Subdivision, in
the locations shown on the Boring Location Sketch, Plate One. The
purpose of these borings and the subsequent percolation testing was
to provide information for the Municipality of Anchorage Department
of Environmental Quality with which to evaluate the suitability of
the soils to accept waste water from soil absorption systems. To this
end, the exploration emphasized percolation testing of the soils with
the results presented on Plates Two through Five~ and establishment of
observation points to observe the free water level~ summarized to date
on Plate Six.
Ail borings were drilled v~th a Nodwell mounted, Mobile B-50
drill fitted with 6" O.D. solid flite auger. Boring 2 and 3 were
drilled to 20' in depth. Boring 4 was drilled to 18' where refusal
was met on a boulder. Boring 1 was drilled to 10' and terminated
due to excessive sloughing of the saturated soils. The writer was
present on-site full time during the exploration to log the observed
soil strata~ visually classifying the soils in the field according
to the "Unified Soils Classification System", presented on Plate ~
Seven, and the Textural Classification System in local use presented
Page 2

1337 E. 72nd Avenue

on Plate Eight. Samples were taken at 5' intervals in each of the
borings from the flights of the auger from near the bit. These
samples will be stored in our laboratory for three months should
additional testing be required.
Upon completion of each boring, 4" perforated PVC pipe was
placed in the boring to allow stabilization of the water level in
the pipe for later observation. The depth to the free water level
in each of the borings was recorded on September 8 and 11, 1978
with the results presented on Plate Six.
In the proximity of each of borings 2, 3, and 4, an additional
shallow test hole was drilled, with 4" perforated pipe installed
to allow percolation testing of the shallow soils. The percolation
tests were performed by a technician under the writer's supervision.
'Ail percolation holes were filled on September 11, 1978, to allow
swelling of the soils overnight, filled again on September t2, 1978,
the~the drop of the water level was measured for four hours. The
results of these tests are presented on the soils logs, Plates Two-
Five.
We trust the foregoing is sufficient to your immediate needs°
V~ile intended to be comprehensive within the limited scope of
this effort, it may not be exhaustive of the possibilities. There-
fore, if questions arise, or if we can be of further service,
please feel free to call.

in each of the borings was recorded on September 8 and 11, 1978
with the results presented on Plate Six.
In the proximity of each of borings 2, 3, and 4, an additional
shallow test hole was drilled, with 4" perforated pipe installed
to allow percolation testing of the shallow soils. The percolation
tests were performed by a technician under the writer,s supervision.
All percolation holes were filled on September 11, 1978, to allow
swelling of the soils overnight, filled again on September 12, 1978,
the~the drop of the water level was measured for four hours. The
results of these tests are presented on the soils logs, Plates Two-
Five.
We trust the foregoing is sufficient to your immediate needs.
?&ile intended to be comprehensive within the limited scope of
this effort, it may not be exhaustive of the possibilities. There-
fore, if questions arise, or if we can be of further service,
please feel free to call.
Very Truly Yours,
John M. Lambe, P.E.
