Subject: Block C, Lot 10, Sunset Hills
Dear Mr. Korpi:
In response to your request the test pit placed on 28 ~4ay 1974
at the subject site was logged by Mr. Kenworthy of Alaska
Testlab's staff. The hole log is attached as Table A; Sheets
1 to 3 are standard explanatory information.
The soils encountered below 3' are suitable for percolation.
Using the relationships p~lished by the Greater Anchorage Area
Borough, the rel.~i~,l¥~clean GM and GP soils should be ~eveloped
at the rate of ~5'f~2 ~r more of absorption area per bedroom.
In addition, the GM/GP soils below 3' should perform adequately
as foundation soils.
The free water level was below the depth of exploration.
We trust the foregoing is sufficient to your immediate needs,
though not necessarily exhaustive of the possibilities. Therefore,
should there be questions do not hesitate to contact the writer.
Very truly yours,

TEST HOLE LOGS
SOILS DESCRIPTIONS
The soil descriptions shown on the logs are the best estimate of the soil charac-
teristics at the time of field examination. Such examinations do not achieve the
precision of laboratory tests for the various properties.
1. The relativs type of soil and the frost classification is shown on the sheet
"Soil Classification Chart."
2. Other criteria:
Boulder - greater than 8"
Gobble - approximately 3" to 8"
Blow Count - blows/6" of 140 lb. weight failing 30"; 2" split spoon. (The
standard penetration is blows/12'.)
Density - estimated by the rate of drilling, type of soil, blow count and
moisture range
PL - Plastic Limit, moisture content being approximated as; above (+) or
below (-) plastic limit (PL) or liquid limit (Lw) as appropriate
Lw - Liquid Limit, see PL
Dilatency - is the ability of wate, r to migrate to the surface upon vibration
or jolting of a sample, an aid ia determining whether a soil is pre.-
dominately a clay or silt
Well graded - uniformity coefficient greater than 7
Poorly graded - uniformity coefficient less than 7 (Uniform particles,
gap graded)
Organic Content - estimated by volume, not particularly precise
Clayey Soils - a field method now being used as an aid to identification
of these soils as a combination ball drop, and rolled thread test in
which a 2" diameter ball of the Sand-Silt-Clay fraction is dropped
2' until a 1" thick pat develops. The diameter of a thread at
crumbling rolled from the resultant pat determines whether clay
or silt predominates.
Dry Strength - a small sample of the soil is formed into a cube and air
dried, and crushed between the fingers. High dry strength indi-
cates clays and low indicates silts.
Water Table - the apparent water table at the time of observation, Often
the actual water table may be higher unless the hole is'allowed to
remain open or is converted to an observation well.
Capillary Fringe - change from moist to very damp, or saturated soil,
usually indicates that water table is close.
Peat ~ Fib-'ous material of macroscopic and microscopic fragments of de-
cayed vegetable matter; very compressible, unsuitable for founda-
tion or embankment. Color light brown to black.
Ao - The upper layer, surface soil or topsoil, containing humus and/or
organic debris, not satisfactory for foundation.

Enclosed is a letter from the Municipal Health Department, requesting,
under Item 3, a letter of non-objection (Encroachment Agreement) to
utilize the ten foot utility easement along the easterly portion of
Lot 10 as additional space for a septic disposal system. The existing
crib is shown on the plat enclosed. Also enclosed is engineering data
prepared by the Department of Transportation and Public Facilities
(DOT&PF), Right of Way Engineering, which ]nay be of assistance.
As shown on the plat, DOT&PF requires 4,338 square feet as additional
right of way for 'the above indicated project. The owners are
concerned for location of an extra septic disposal site should their
present system fail.
As a matter of information, DOT&PF has no objection to a waiver of a
set-back requirement from the new proposed right of way line along the
northern boundary of Lot 10.
We request that Chugach approve an Encroachment Agreement
ground use of the utility easement area for purposes of
drainage field.

Mr. John H. Korpi

Anchorage, Alaska 99515
Subject: Lot 10 Block C Sunset Hills Subdivision
Right of way easement
Dear Mr. Korpi:
On March 18, 1987 this office was approached by Carol
Eaton, of the State of Alaska Right of Way section,
concerning the proposed acquisition of a portion of Lot 10
Block C Sunset Hills. At that time Ms. Eaton conveyed your
concern over a replacement site for your septic system.
After reviewing our files we were able to determine that a
replacement system could be installed. Based on the
existing as-built and soils report a trench type system
could be installed under the following conditions:
1) The existing pit location must be defined, as regards
the existing property lines and the proposed property line
after right of way acquisition by the State of Alaska.
2) That an easement be granted, by the State of Alaska, to
ensure sufficient area should the trench extend into the
Seward Hwy. right of way. Ms. Eaton stated such an
arrangement could be made.
3) A letter of non-objection, concerning the use of the
utility easement for septic disposal, be obtained from the
utilities utilizing the easement along the easterly portion
of lot 10. Ms. Eaton stated that her office would handle
that agreement.
In view of obtaining the forgoing requirements this
department can then establish the location of the upgrade
area. At this time we can foresee no reason to deny the
issuance of the appropriate separation waivers. Should it
become necessary to replace the existing pit, at a future
date, the waivers would be on file so as not to hinder the
permit process. Should you have any further questions
please contact our office at 343-4744.
Sincerely,
Daniel N. Bolles
