LETTER REPORT
Soils Studies
Deer Park Subdivision
Peters Creek, Alaska
Introductioq
On Wednesday, September 20, 1978, Mr. Les Brattain of Tryck,
Nyman and Hayes verbally authorized Gary Player Ventures to conduct
an investiEation of soils conditions in portions of the proposed
Deer Park Subdivision, Peters Creek, Alaska. We agreed on thc proposed
locations of test pits and selected Chuck's Bac¥~oe Services of
Anchorage, A~aska to excavate the pits.
On Fr~day, September 22, ~978, three test pits were excavated
and the materials described. On Saturday, September 25, ~978, I
returned to the site to conduct percolation tests at test pits "B"
and "C". The locations of the test pits~are sho%.m on the Location
Map (attached).
Soils and Groundwater
Soils at the site consist of silty sands and gravelly silty
sands overlain by va~yingthicknesses of clean, well graded gravel.
The ~:ater table v~as not encountered in the three test holes; clayey
gravels encountered belo~; 8 feet in test pit "A" are wet, but per-
meable s~nd lenses in the gravel are not water-bearing.
'The materials encountered in test pits "A", "B", and "C" are
described in the attached Soils Logs. Percolation rates for the silty
sands encountered in test pits "B" and "C" are shov~ on the Soils Logs.

SUBSURFACE INVESTIGATION FOR PETERS CREEK ESTATES SUBDIVISION
Peters Creek, Alaska
The subsurface investigation was 'conducted on Hay 13, l~ and 15,
1~75 using a Case 580 backhoe to excavate the test pits,
Test pit sltes were chosen and logging was performed by
Harvln Beyer, P.E.
A total of h test pits were placed at Iocatlons on the property so
as to reasonably represent all soils within the proposed subdivision.
The test pits were located by pacing from topographic features determined
from the topographic map of the area. Therefore, all locations are
approximate.
The proposed subdivision is heavily tree covered and the soil
consists of I to 2 feet of organic topsoil underlaln with clean NFS
sandy gravel in various thicknesses. Underneath the NFS material is an
F-1 sandy, silty, gravel with low amounts of silt. Some large boulders
exist at random locations throughout the area.
The test pit observations indicate that there is adequate NFS
sandy gravel on the site for the construction of the proposed subdivision
roads.
An analysis of the material encountered Indicates that all portions
of the subdivision would be suitable for on-site sewage disposal systems
consisting of septic tank and ]eachlng fields or leaching pits.
All soils analysls was by visual classification. One soil sample was
retained from each test pit.

Municipality Case #S-48SS
introduction
On ThUrsday, October 19, 1978, Mr. Los Brattain and I met with
Mr. Les Buchholz, Environmental Ensineeriu~ Manager, Department of
Health and Environmental Protection, Municipality of Anchorase.
We discussed the status of soils studies at the proposed Deer Park
Subdivision and ~ointly selected the locations for ~ additional
tes~ pits. We' agreed that the three additional tests, if satisfactory,
would be sufficient to allow the Municipality to review your proposed
subdivision.
On Friday I contacted an excavator in tho Peters Creek area and
showed him the locations of the additional test pits. A small Case
bacl~oe capable of digging to nine feet below ground was selected, as
Mr. Bucb~olz had agreed that the nine existing excavations had
that groundwater levels were at least 15 feet below ground in the
area· On Saturday, October 21, 1978 the three additional test pits
were dug and the materials described.
Soils and Groundwater
Soils in the three test pits were even better than could have
been predicted from the previous studies· All three sites were underlain
by clean well Eraded gravels to depths of at least eight feet. Silty
loose sands mantled the gravels from the surface to depths of 1 to ~.5
feet below ~round.
Gravels in Test Pits E and F were dry. A small amount of free-
~ater was oerchcd on silty sand at 8.5 feet below Eround'in Test Pit
D. The wa~er was probably surface water percolatinM do~mward after
hea~-y rains and wet snow of tho previous week.

F-! sandy, silty, gravel with Ic~ amounts of slit. Some large boulders
exist at random locations throughout the area.
The test pit observations Indicate that there is adequate NFS
sandy gravel on the slte for the construction of the proposed subdlvls|on

An analysls of the material encountered Indicates that all portions
of the subdivision would be suitable for on-site sewage disposal systems
consisting of septic tank and leaching fields or leachlng plts,
All soils analysis was by visual classlflcatlon. One soll sample was
retained from each test pit.

Deer Park Subdivision
Peters Creek, Alaska
Introduction
On Wednesday, September 20, 1978, Mr. Les Brattain of Tryck,
Nyman and Hayes verbally authorized G~.ry Player Ventures to conduct
an znvestzga~zon of soils conditions ~n portions of the proposed
Deer Park Subdivision, Peters Creek, Alaska. We agreed on the proposed
locations of test pits and selected Chuck'f Backhoe Services of
· Anchorage, A~aska to excavate the pits.
On Frzday, September 22, 9978, three test pits were excavated
and tho materials described. On Saturday, September 25, ~978, I
returned to the site to conduct percolation tests at test pits "B"
and "C". The locations of the test pits are sho~m on the Location
Map (attached).
Soils and Ground[.zater
Soils at the site consist of silty sands and gravelly silty
sands overlain by varying thicknesses of clean, ~cll graded gravel.
The water table %.:as not encountered in the t.hree test holes; clayey
gravels encountered below 8 feet in test pit "A" are wet, but per-
meable sand lenses in the gravel are not %.~ater-bearing.
The materials encountered iu test pits "A", "B", and "C" are
described in the attached Soils Logs. Percolation rates for the silty
sands encountered in test pits "B" and "C" are shovm on the Soils Logs.

SUBSURFACE INVESTIGATION FOR PETERS CREEK ESTATES SUBDIVISION
Peters Creek, Alaska
The subsurface investigation was conducted on Hay 13, 14 and
1978 using a Case 580 backhoe to excavate the test pits.
Test pit sites were chosen and Iogg|~g was performed by
Harvln Bayer, P.E.
A total of 4 test pits were placed at locations on the property so
as to reasonably represent a11 soils within the proposed subdivision.
The test pits were located by Pacing from topographic features.determined
from the topographic map of the area. Therefore, all locations are
approximate.
The proposed subdivision is he'avily tree covered and the sol1
consists of 1 to 2 feet of organic topsoil underlain with clean NFS
sandy gravel In various thicknesses. Underneath the NFS material is an
F-1 sandy, silty, gravel with Iow amounts of s|lt. Some large boulders
exist at random locations throughout the area.
The test pit o~servatlons indicate that there is adequate NFS
sandy gravel on.the site for the construction of the proposed subdivision
roads.
An analysls of the material encountered indicates that al1 portions
of the subdivision would be suitable for on-site sewage disposal systems
consisting of septic tank and leaching fields or leaching pits.
All soils analysis was by visual classlfication. One sol1 sample was
retained from each test pit.
