This report presents the results of our subsurface exploration
and engineering study for' the proposed subdivision project. The
proposed subdivision and approximate locations of the explora-
tions accomplished for this study are presented on the Site Plan,
Figure 2.
!

The purpose of this study was to explore subsurface conditions at
the site from which conclusions ~nd recommendations for building
foundations and septic systems could be formulated. The scope of
work consisted of field exploratioins and engineering analysis
from a geotechnical standpoint.

The field exploration program for this study consisted of a
series of holes approximately located on each full lot of the
real propert~ located on the El/2 of the NE1/4 of Sec 5~ T15N,
R1W of the Seward Meridian; Lots 15,16~27~2~,50,42~4~,44,55~and
~6 plus the portions of Lots 5,14,17,26,and 51 located east of
the rail road tracks. Exploration procedures are presented in'a

this proposed subdivision project in a~cordance with generally
accepted engineering practices. Th'e test results or the test
holes are not to be used for acquiring septic system permits, but
are for evaluation purposes only.
SITE AND PROJECT DESCRIPTION
The proposed subdivision project lies within
Alaska, adjacent to and east of the Alaska Railroad
Figure 1. The area has gentle roiling land with
varing from 70' to 150'.
Peters Creek,
as shown in
elevations
Vegetation consists of small birch, black spruce, alders and
assorted iow brush and ground cover with occasional downfall.
The subdivision is divided in half by a ridge cutting across the
land from southwest to northeast. The southeast section of the
area is marshy with signs of high ground water present throug-
hout, while the northwest section is lower in elevatioin but much
drier.
An old abandoned power line easement cuts across the southeast
section paralleling the ~idge giving the project its only cleared
area.
The Proposed subdivision project will combine ail of the existing
lots together into one subdivision with approximately 60 new half
· acre lots. It is anticipated 'that a community well will be
established to provide water and each lot will have its own
septic system.

SUBSURPACE EXPLORATION
The exploration consisted of digging and logging some eleven test
holes 'evenly spaced thoughout the subdivision area. The holes
were dug by Boyd Alaska with a backhoe moented on the back of a
John Deere 450 dozer. Holes i and 2 were not dug due to the high
ground water and overburden conditioins in the area preventing
access. Holes 5,4 and 5 however, are typical in nature to holes
I and 2 and is anticipated to be very similar.
Care was taken to prevent the knock down of many trees during the
-transitition from hole to hole inorder to keep the appearance of
the lots.
With the exception of holes 5,4,5, and 6 the test
to a' depth of 15 feet ~hich is the maximum extention
backhoe. The holes encountering high water were only
approximately 8 feet to check for foundation material.
holes were dug
of the
dug to
A percolation test was attempted on test holes 7 and 10, but due
to the clean material encountered the water flowed through the
· material faster than could be measured. No other tests were
performed at the site, and field classifications of the soils
were made ¥isually.
SUBSURFACE CONDITIONS
The subsurface soils as examined were fairly uniform throughout
the area and consist of organib overburden overlying an alluvial '
sandy gravel and gravelly sand deposit, see test hole logs in
Appendix A.
The organics encountered at the surface are brown~ fibrous, very
soft and moist to saturated. This layer supports a thick crop of
'trees as described in the introduction.
Ground water was encountered beneath the organic mat on holes 5
through 6 and most likely would have been encountered at holes 1
and 2. At the lower, elevations represented by holes 7 through
13,
believe that the water at the higher elevations is perched and
· ~heldup by a dense material located at a lower elevation. This
erea is located on a bench and may be able to be drained, see
Recommendations and Conclusions.
no ground water was encountered. This leads the engineer to
The sands and gravele located beneath the organic mat is very
clean and contains an oocasional coble. Most of the gravel is
to 2 inches in maximum size, and could be used as a NFS gravel
'source for developing roads and foundations.
The various types of soils are indicated as well as the depths
where the soils or characteristic of the soils changed in Appen-
dix A. It should be noted that these changes are gradual 'and can
be interpreted between the test holes.
FOUNDATION AND SEPTIC SYSTEM ANALYSIS
It is understood that the proposed development of the site will
consist of wood framed single family dwellings. The material is
well suited to support standard wall foundations with footings.
4
The bearing capacity of the soil-exceeds 600] psf for m design
value; however, this material must be compacted to a dense state
directly under the footings to prohibit settlement.
Caution should be taken whenever trenchs are excavated though the
subsurface material to prevent collapse of the walls, ~ince this
material will sluff readily.
It is also understood that each lot will have its own' septic
system. Again the material encountered in the 4 to 12 foot depth
is well suited for septic disposal. This material is a sandy
gravel classified as a well graded gravel (GW) and would have a
perculation rate exceeding 2 minutes per inch. The Municipality
of Anchorage rates this material for septic permits at 85 square
feet per bedroom. It is however suggested that -each lot be
tested in the location of its proposed septic system to insure
the consistence of the soil.
The area of the site with the ground water encountered at or just
below the surface is not acceptable at this time for foundations
or septic systems. I~ the area were to be drained, the soils
would be also suitable for construction once consolidation of the
material was accomplished by means of compaction.
CONCLUSIONS AND RECOMMENDATIONS
In summary, the soils at the proposed subdivisioin site are well
suited for residentual construction of houses and septic systems
in the areas not encountering high ground water.
The areas with the high ground water can possibly be improved by
5
draining the water to a depth of 12 feet below the surface. This
can be accomplished by wells, drainage ditches, or perforated
drainage pipes. The'latter is recommended for econmics over a
'well system and safety over a trench system. The perforated pipe
should be buried at various locations thoughout the area at about
15 to 20 feet in depth, and should be located so that septic
systems will not contaminate the flow of the pipe creating a
potential health problem. Outflow will need to dump into
existing drainage streams to prevent flooding of adjacent
property. It is anticipated that drawdown of the water level
will take approximately 1 to 2 years depending upon the number
and location of the drainage pipes.

drainage plan
There is currently no surface drainage visible
within this subdivision. The entire Tract is
heavily vegatated which prevents any noticeable
erosion from the slopes on this property. Any
developement of these lots would adhere to the
surrounding trends of clearing enough of the lot
to construct a house thereby reducing the amount
of erosion that would take place by deforesting
the entire lot.

The drainage pattern within this subdivision
follows the existing slope which runs
predominately from the south to the north. Along
the Eastern Border of the property, a drainage
ditch has been constructed paralleling Knik Vista
Drive. This ditch carries runoff to the Northern
border where it joins an additional drainage
ditch that runs along Alder Leaf Court to join
into the drainage ditch serving Inlet Vista
Circle. From this point any surface drainage
travels in a southwesterly direction towards Knik
Inlet located to the West. There are currently
three(3) ditches located on this tract which were
constructed approximately ten years ago. The
purpose of these ditches was an attempt to lower
high groundwater levels found in the area when
test holes were excavated. The location of these
ditches can be seen on the attached drawing.
3e
Drainage from this subdivision will'not affect
any other subdivision in this area and drainage
patterns will not be changed slgnl~lcan~ y as a
result of this subdivision.
This subdivision plat will provide for drainage easements
as needed or required. Water which originates within the
subdivision (snow melt and rain) will follow historical
runoff patterns.

(proposed)
This letter addresses concerns regarding a drainage
for the referenced proposed subdivision.
The drainage pattern within this subdivision
follows the existing slope which runs
predominately from the south-east to the north-
west. Along the Eastern Border of the property,
a drainage ditch has been constructed paralleling
Knik Vista Drive. This ditch carries runoff to
the Northern border where it joins an additional
drainage ditch that runs along Alder Leaf Court
to join into the drainage ditch serving Inlet
vista Circle. From this point any surface
drainage travels in a southwesterly direction
towards Knik Inlet located to the West. There
are currently three(3) ditches located on this
tract which were constructed approximately ten
years ago. The purpose of these ditches was an
attempt to lower high groundwater levels found in
the area when test holes were excavated. The
location of these ditches can be seen on the
attached drawing. According to groundwater
monitoring done on several test holes excavated
in the fall of 1995, the level of groundwater
appears to have dropped approximately three to
five feet making developement of these lots more
feasible. These ditches are approximately eight
to twelve feet deep, lined with filter fabric and
filled with approximately six to eight feet of
sewer rock and backfilled.
17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASY, A 99577
plan
Page Two
There is currently no surface drainage visible
within this subdivision. The entire Tract is
heavily vegatated which prevents any noticeable
erosion from the slopes on this property. Any
developement of these lots would adhere to the
surrounding trends of clearing enough of the lot
to construct a house thereby reducing the amount
of erosion that would take place by deforesting
the entire lot.
Drainage from this subdivision will not affect
any other subdivision in this area and drainage
patterns will not be changed significantly as a
result of this subdivision.
This subdivision plat will provide for drainage easements
as needed or required. Water which originates within the
subdivision (snow melt and rain) will follow historical
runoff patterns.
If you require additional information, please contact me at
694-2979.

S-7384: Knik View Subdivision
Attention:
Jerry Weaver
This will continue correspond on the Knik View Subdivision(Case S-7384
and will supplement the comments made in our memorandum, dated February
21, 1984. The comments made in the above referenced memorandum are still
valid, and are considered to be critical. A reiteration of these comments
is as follows:
(i)
Additional soils tests must be availed prior to preliminary approval.
There were only four(4) soils tests taken in the area now defined
as Lots 1 - 17 Block 2, and one in Lots 1 - 5 Block 1. At least
six(6) additional soils tests mu~t be taken so that a representative
indication of the soils characteristics can be determined.
(2)
In the original package of information submitted, the soils test
sites were not specifically located with respect to the proposed lots.
We have had to estimate the locations of these sites, which is not
acceptable.
(3)
The plat originally submitted does not properly depict the topography
of the system. Again, we had to make several assumptions as to
contour interval, slope, etc. This is not acceptable.
(4)
Lots 18, 19, 20, 21, 22 Block 2 are located in a steeply sloped area.
These lots are also immediately adjacent to an area(Tract A) which
is underlain with shallow groundwater. Prior to preliminary approval,
the following additional information must be availed:
(a)
The slope of each lot must be confirmed, and then an area must be
delineated on each lot where the original and two(2) replacement
wastewater disposal systems can be installed. The area set aside
for these systems must be in an area of less than 25%.
(b)
Soils tests were perfo~aed on only two(2) of these five(5) lots
(exact location unknown). These lots are all adjaceqt to an area
located upstructure, that is underlain with shallow groundwater.
There must be at least two(2) more soils tests taken(Lots 18, 19)
and water monitoring Zests must be taken on all soils test holes
for at least fourteeh(14) days prior to preliminary approval.
(5)
Subsequent to receiving the original package and furnishing our comments
thereon, we received a proposed "dewatering process" for the area to be
tracted(Tract A). This proposal is fraught with inconsistencies and
inadequacies. Some of these are as follows:
91-010 (4/76)
Community Planning Department
February 24, 1984
Page Two
(a)
The theory of lowering a groundwater table by using a subsurface
drain system(curtain drain) is to install a deep drainage system
perpendicular to the direction of subsurface flow, and then divert
the intercepted flow to an outfall located away from and down-
structure of the area to be drained. The proposed system intercepts
the subsurface flow somewhat parallel, to the direction of flow,
which will have minimal if any effect on lowering the groundwater
table.
(b)
The first'outfall of the system as proposed is directly into the
"nearest road ditch". This is totally unacceptable because of the
potentially large vo].ume of water that will be flowing continuously.
(c)
The final outfall of the system is proposed to be onto the
existing Alaska Railroad right-of-way. There is every reason to
believe that the Alaska Railroad would never allow this to occur.
As shown on Phase II of the proposed subsurface drainage system, no
septic tank systems would be allowed inside a 100' setback from
the drainage culverts. If this were indeed followed, then Lots
3, 5, 6 Block 2 and Lots 3, 5, 6, 7, 8 Block 1 could not support
on-site disposal systems. This conclusioh also takes into
consideration slope and the MEA r~ght-of-way easement.
In summary, there has not been sufficient usable information availed to this
Department for any form of preliminary plat approval on this proposed
subdivision, and the request for approval should be denied and returned for
redesign.
It should also be brought to the attention of the developer that any fourteen(14)
day monitoring of ground water requested to date by this Department, does not
negate the subsequent need for ninety(90) day monitoring. A standard requirement
of this Department is for ninety(90) day monitoring of ground water levels in
any test hole/pit where ground water was encountered or even suspected of being
within twelve(12) feet of the ground surface. The last thirty(30) days of this
ninety(90) day monitoring period must occur between June 1 and October 15, with
final results provided to this Department between preliminary and final plat
approval.

Plat Comments
New information has been brought to our attention since the
original review of plats to be heard on March 7, 1984o
Specifically, additional comments are submitted for the
following two subdivision plats.
S-7458 GRAZELDA SUBDIVISION
The petitioner has provided for an adequate creek
maintenance easement for this plat, however, the
creek is currently not in the location shown on
the plat. Substantial creek realignment will be
necessary. This watercourse is Little Campbell
Creek, an anadromous fish stream, and any
instream work will require both a Title 16 permit
from Alaska Department of Fish & Game and a
Section 404 permit from the Corps of Engineers.
It is recommended that the Title 16 permit be
obtained prior to approving this plat because of
the potential problems and time involved with
securing the permit. Extensive mitigation
measures and habitat enhancement will be required
to relocate this stream, and that information
should be provided to the Platting Board for
their review of this project.
KNIK VIEW SUBDIVISION
The proposed subdivision is located in an area
with very serious environmental constraints:
steep slopes, high groundwater table, and poor
access. The proposed subdivision, with the large
utility easement and the setbacks requirements
for the storm drainage system, provides several
lots which could be difficult on which to build.
In addition, the density proposed is within the
high range allowed in the Comprehensive Plan.
Considering the character of the surrounding
neighborhood (rural, low density) and the signi-
ficant environment constraints, Physical Planning
recommends that the proposed plat be returned for
redesign to address the items identified above
and to consider a cluster plat.

S-7356B COLUMBIA PARK SUBDIVISION ADDITION NO. 4
Physical Planning supports the recommendation of
the Platting Board to delay construction of this
project until 1986 because of present inadequate
public facilities. This subdivision and this area
of town has received careful review by the Planning
Department, Public Works Department, and other
Departments within the Municipality and it has been
our belief that the development at the density pro-
posed is not current serviced by adequate public
facilities. Therefore, we recommend that condition
no. 16 in the approval for this subdivision case
remain in tact.

Plat Comments
Area is classified as special study area° Information
on plat is inadequate to determine if subdivision meets
requirements of special study area. All other require-
ments of Code appear to be met. We are concerned that
Lots 3, 4, and 5, Block 1, and Lots 35, 36, and 37,
Block 2, may be unable to be built on because of electric
and telephone easement and topography. DB
Approved as meeting minimum requirements of Code. Struc-
tures on lot being constructed under approved land use
permit. As-built survey needed on plat to determine if
structures cross any property lines. DB
Approved as meeting minimum requirement of Code. Struc~
ture on lot currently is in violation of secondary front
yard setback requirement° Rep!at would correct current
nonconformity. DB
*This appears not to be a cost effective solution for the
Municipality to resolve a private problem of a front
yard setback encroachment by releasing public ROW. JFH
As-built survey needed on plat to determine if the struc-
ture on the property will meet minimum setback requirement.
There is a proposed rezone of this and surrounding prop-
erty to R-7 pending before the Planning and Zoning Commission.

PETERS CREEK ALASKA
INTRODUCTION
This report presents the results of our subsurface exploration
and engineering study for the proposed subdivision project. The
proposed subdivision and approximate locations of the explora-
tions accomplished for this study are'presented on the Site Plan,
Figure 2.
The purpose of this study was to explore subsurface conditions at
the site from which conclusions and recommendations for building
foundations and septic systems could be formulated. The scope of
work consisted of field exploratioins and engineering analysis
from a geotechnical standpoint.
The field exploration program for this study consisted of a
series of holes approximately loc~ed on each full lot of the
real property located on the El/2 of the NE1/4 of Sec 57 T15N,
RIW of the Seward Meridian; Lots 15,16,27~29,50,42,4~,44,55,and
56 plus the portions of Lots 5,14,17,26,and 51 located east of
the rail road tracks. 'Exploration procedures are presented in a
subsequent section of this report and interpretive soil logs of
the exploration are presented in Appendix A.
This report has been prepared for the exclusive use of TYEE
DEVELOPMENT INC. and their agents~ for specific application to
Appendix A.
The organics encountered at the surface are brown, ~i~o~s~ very
soft and moist to saturated. This layer supports a thick crop
trees as described in the introduction.
Ground water wae encountered beneath the organic mat on holes ~
~hrough 6 and most likely would have been encountered at holes 1
and 2. At the lower, elevations represented by holes 7 through
15~ no ground water was encountered. This leads the engineer to
believe that the water at the higher elevations is perched and
· held up by a dense material located at m lower elevation. This
area is located on a bench and may be able to be drained, see
Recommendations and Conclusions.
The sands and gravels l~cated beneath the organic mat is very
clean and contains an occasional coble. Most o~ the gravel is 1
to 2 inches in maximum size, and could be used as a NFS gravel
-source for developing roads and foundations.
The various types of soils are indicated as well as the depths
where the s~ils or characteristic of the soils changed in Appen-
dix A. It should be noted that these changes are gradual 'and can
be interpreted between the test holes.
FOUNDATION AND SEPTIC SYSTEM ANALYSES
It is understood that the proposed development of the site will
consist of wood framed single family dwellings. The material is
well suited to support standard wall foundations with footings.

PETERS CREEK ALASKA
INTRODUCTION
This report presents the results of our subsurface exploration
and engineering study for'the proposed subdivision project. The
proposed subdivision and approximate locations of the explora-
tions accomplished for this study are presented on the Site Plan,
Figure 2.

The purpose of this study was to explore subsurface conditions at
the site from which conclusions and recommendations for building
foundations and septic systems could be formulated° The scope of
work consisted of field exploratioins and engineering analysis
from a geotechnicai standpoint.
L

I_
The field exploration program for this study consisted of a
series of holes approximately located on each full lot of the
real property located on the E1/2 of the NE1/4 of Sec 5~ T15N,
R1W of the Seward Meridian; Lots 15,16,27,29,30,42~4~,44,55,and
56 plus the portions of Lots 5,14,17~26,and 51 located east of
the rail road tracks. Exploration procedures are presented in a
subsequent section of this report and interpretive soil logs of
the exploration are presented in Appendix A.
This report has been prepared for the exclusive use of TYEE
DEVELOPMENT INC. and their agents~ for specific application to
this proposed eubdivision project in accordance with generally
accepted engineering practices, lh'e test results or the test
holes are not to be used for acquiring septic system permits, but
are ~or evaluation purposes only~
SITE AND F'ROJECT DESCRIPTION
The proposed subdivision project lies within Peters Creek~
Alaska~ adjacent to and east of the Alaska Railroad as shown in
Figure 1. The area has gentle rolling land with elevations
varing from 70' to 150'

SUBSURFACE EXPLORATION
The exploration consisted of digging and logg:ng some eleven test
holes 'evenly spaced thoughout the subdivision area. The holes
were dug by Boyd Alaska with a backhoe mounted on the back of a
John Deere 450 dozer. Holes I and 2 were not dug due to the high
ground water and overburden conditioins in the area preventing
access. Holes 3,4 and 5 however, are typical in nature to holes
1 and 2 and is anticipated to be very similar.
Care was taken to prevent the knock down of many trees during the
-transitition ~rom hole to hole inorder to keep the appearance of
the lots.
With the exception of holes 3,4,5, and 6 the test holes were dug
to a depth of 15 feet which is the maximum extention of the
backhoe. The holes encountering high water were only dug to
approximately 8 feet to check for foundation material.
A percolation test was attempted on test holes 7 and 10, but due
to the clean material encountered the water flowed through the
material faster than could be measured. No other tests were
performed at the site, and field classifications of the soils
were made visually.
SUBSURFACE CONDITIONS
The subsurface soils as examined were fairly uniform throughout
the area and consist of organi~ overburden overlying an alluvial
sandy gravel and gravelly sand deposit, see test hole logs in
f
[

L
L
Appendix A.
The organics encountered at the surface are brown, fibrous~ very
soft and moist to saturated. This layer supports a thick crop of
· trees as described in the introduction.
Ground water was encountered beneath the organic mat on holes ~
through 6 and most likely would have been encountered at holes 1
and 2. At the lower elevations represented by holes 7 through
13~ no ground water was encountered° This leads the engineer to
believe that the water at the higher elevations is perched and
· held up by a dense material located at a lower elevation. This
area is located on a bench and may be able to be drained, see
Recommendations and Conclusions.
The sands and gravels located beneath the organic mat is very
clean and contains an occasional coble. Most of the gravel is 1
to 2 inches in maximum size~ and could be used as a NFS gravel
· source for developing roads and foundations.
The various types of soils are indicated as well as the depths
where the soils or characteristic of the soils changed in Appen-
dix A. It should be noted that these changes are gradual 'and can
be interpreted between the test holes.
FOUNDATION AND SEPTIC SYSTEM ANALYSIS
It is understood that the proposed development of the site will
consist of wood framed single family dwellings. The material is
well suited to support standard wall foundations with feotings.
4
The bearing capacity of the soil. exceeds 6000 psf for a design
value; however, this material must be compacted to a dense state
directly under the footings to prohibit settlement.
Caution should be taken whenever trenchs are excavated though the
subsurface material to prevent collapse of the walls, eince this
material will sluff readily.
It is also understood that each lot will have its own' septic
system. Again the material encountered in the 4 to 12 foot depth
· is well suited for septic disposal. This material is a sandy
gravel classified as a well graded gravel (GW) and woold have a
perculation rate exceeding 2 minutes per inch. The Municipality
of Anchorage rates this material for septic permits at 85 square
feet per bedroom. It is however suggested that -each lot be
tested in the location of its proposed septic system to insure
the consistence of the soil.
The area o~ the site with the ground water encountered at or just
below the surface is not acceptable at this time for foundations
or septic systems. If the area were to be drained~ the. soils
would be also suitable for construction once consolidation of the
material was accomplished by means of compaction.
CONCLUSIONS AND RECOMMENDATIONS
In summary, the soils at the proposed subdivisioin site are well
suited for residentual construction o~ houses and septic systems
in the areas not encountering high ground water.
The areas with the high ground water can possibly be improved by

draining the water to a depth of 12 feet below the surface. This
can be accomplished by wells~ drainage ditches, or perforated
drainage pipes. The'latter is recommended for econmics over a
-well system and safety over a trench system. The perforated pi~e
should be buried at various locations thoughout the area at about
15 to 20 feet in depth, and should be located so that septic
systems will not contaminate the flow of the pipe creating a
potential health problem. Outflow will need to dump into
existing drainage streams to prevent flooding of adjacent
property. It is anticipated that drawdown of the water level
will take approximately I to 2 years depending upon the number
and location of the drainage pipes.

this proposed subdivision project in accordance with generally
accepted engineering practices. Th'e test results or the test
holes are not to be used for acquiring septic system permits, but
are for evaluation purposes only.
SITE AND PROJECT DESCRIPTION
The proposed subdivision project lies within Peters Creek,
Alaska, adjacent to and east of the Alaska Railroad as shown in
Figure 1. The area has gentle rolling land with elevations
raring from 70' to 150'.
Vegetation consists of small birch, black spruce, alders and
assorted low brush and ground cover with occasional downfall.
The subdivision is divided in half by a ridge cutting aoross the
land from southwest to northeast. The southeast section of the
area is marshy with signs of high ground water present throug-
hout, while the northwest section is lower in elevatioin but much
'drier.
An old abandoned power line easement cuts across the southeast
section paralleling the ~idge giving the project its only cleared
area.
The Proposed subdivision project
will combine all of the existing
lots together into one subdivision
with approximately 60 new half
acre lots. It is anticipated that a community well will . be
established to provide water and each lot will have its own
septic system.

SUBSURFACE EXPLORATION
The exploration consisted of digging and logging some eleven test
holes 'evenly spaced thoughout the subdivision area. The holes
were dug by Boyd Alaska with a backhoe mounted on the back of a
John Deere 4~0 dozer. Holes 1 and 2 were not dug due to the high
ground water and overburden conditioins in the area preventing
access. Holes 5,4 and 5 however, are typical in nature to holes

SITE AND PROJECT DESCRIPTION
The proposed subdivision project ,~ lies within Peters Creek,
Alaska, adjacent to and east of the Alaska Railroad as shown in
Figure 1. The area has gentle rolling land with elevations
varing from 70' to 150'.
Vegetation consists of small birch, black spruce, alders
assorted low brush and ground cover with occasional downfall.
The subdivision is divided in half by a ridge cutting across the
land from southwest to northeast. The southeast section of the

SUBSURFACE EXPLORATION
The exploration consisted of digging and logging some eleven test
holes 'evenly spaced thoughout the subdivision area. The holes
were dug by Boyd Alaska with a backhoe mounted on the back of a
John Deere 450 dozer. Holes i and 2 were not dug due to the high
ground water and overburden conditioins in the area preventing
access. Holes 5,4 and 5 however, ~re typical in nature to holes
1 and 2 and is anticipated to be very similar.
Care was taken to prevent the knock down of many trees during the
transitition from hole to hole inorder to keep the appearance of
the lots.
With the exception of holes 3,4,5, and 6 the test holes were dug
to a depth of 15 feet which is the maximum extention of the ·
backhoe. The holes encountering high wate~ were only dug to
approximately 8 feet to check for foundation material.

SUBSURFACE CONDITIONS
· The subsurface soils as examined were fairly uniform throughout
the area and consist of organic overburden overlying an alluvial
sandy gravel and gravelly sand deposit, see test hole logs in

soft and moist to saterated. This layer suppQrts a thick crop of

Recommendations and Conclusions.
no ground water was encountered. This leads the engineer to
The sands and gravels located beneath the organic mat is very
clean and contains an occasional coble. Most of the gravel is 1
to 2 i~ches in maximum size, and could be used as a NFS gravel
'source ¥or developing roads and ~oundations.
The various types of soils are indicated as well as the depths
where the soils or characteristic of the soils changed in Appen-
dix A. It should be noted that ~these changes are gradual 'and can
be interpreted between the test holes.
FOUNDATION AND SEPTIC SYSTEM ANALYSIS
· It is understood that the proposed development of the site will
consist of wood framed single ~amily dwellings. The material is
well suited to support standard wall foundations with ~ootings.
4
The bearing capacity of the soil e~:ceeds 6000 psf for a design
value; however, this material must be compacted to a dense state
directly under the footings to prohibit settlement.
Caution should be taken whenever trenchs are excavated though the
subsurface material to prevent collapse of the walls, ~ince this
material will sluff readily.
It is also understood that each l'ot will have its own' septic
system. Again the material encountered in the 4 to 12 foot depth
· is well suited for septic disposal. This material is a sandy
gravel classified as a well graded gravel (GW) and would have a
perculation rate exceeding 2 minutes per inch. The Municipality
of Anchorage rates this material for septic permits at 85 square
feet per bedroom. It is however suggested that .each lot be
tested in the location of its proposed septic system to insure
the consistence of the soil.
The area of the site with the
below the surface is not acceptable at this time for
or septic systems. I~ the area were to be drained,

material was accomplished by means o~ compaction.

the
CONCLUSIONS AND RECOMMENDATIONS
In summary, the soils at the proposed subdivisioin site are well
suited for residentual construction of houses and septic systems
in the areas not encountering high ground water.
The areas with the high ground water can possibly be improved by
5
draining the water to a depth of 12 feet below the surface. This
can be accomplished by wells~ drainage ditches, or perforated
drainage pipes, The latter is recommended for econmics over a
~well system and safety over a trench system. The perforated pipe
should be buried at various locations thoughout the area at about
15 to 2(I feet in depth, and should be located so that septic
systems will not contaminate the flow of the pipe creating a
potential health problem. Outflow will need to dump into
existing drainage streams to prevent flooding of adjacent
property. It is anticipated that drawdown of the water level
will take approximately 1 to 2 years depending opon the number
and location of the drainage pipes.
The recommendations of this report are based on the assumption
that soil conditions do not deviate from those disclosed in the
test holes. If any variations or undesirable conditions are
encountered during development, we should be notified so that
supplemental recommendations can be furnished.

KNIK VIEW SUBDIVISION
PETERS CREEK ALASKA
This report presents the results of our subsurface exploration
and engineering study for the proposed subdivision project. The
proposed subdivision and approximate locations of the explora-
tions accomplished for this study'are presented on the Si~e Pla~,
Figure 2.
The purpose of this study was to explore subsurface conditions at
the site from which conclusions and recommendations for building
foundations and septic systems could be formulated. The scope of
work consisted of field exploratioins and engineering analysis
from a geotechnical standpoint.
The field exploration program for this study originally consisted
of a series of holes approximately located on each full parcel of
the real property located on the E1/2 of the NE1/4 of Sec 5,
T15N, R1W of the Seward Meridian; Lots
15~16,27~29,30,42,4~44~55~and 56 plus the portions of Lots
5,14,17,26,and 51 located east of the rail road tracks.
Additional test holes were added after lots were established.
Exploration procedures are presented in a subsequent section of
this-report and interpretive soil logs of the exploration are
presented in Appendix A.
This report has been prepared for the exclusive use of TYEE
DEVELOPMENT INC. and their agents, for specific ~pplication to
this proposed subdivision project in accordance with generally
'accepted engineering practices. The test results or the test
hol~s are not to be used for acquiring septic system permits, but
are for evaluation purposes only.

The Proposed subdivision project will combine all of the e~isting
lots together into one subdivision with approximately 40 new half
acre lots. It is anticipated that a community well will be
established to provide water and each lot will have its own
septic system. ~
SUBSURFACE EXPLORATION
The exploration consisted of digging and logging some eleven test
holes initially in October 1983 and seven additional holes in
March 1984 and were evenly spaced thoughout the subdivision area.
The holes were dug by Boyd Alaska with a backhoe mounted on
back of a John Deere

Care was taken to prevent the knock down of many trees during the

A percolation test was attempted on test holes 7 and 10~ but due
to the clean material encountered the water flowed through the
material faster than could be measured. No other tests were
performed at the site, and field classifications of the soils
were made visually.
SUBSURFACE CONDITIONS
The subsurface soils as examined were fairly uniform

sandy gravel and gravelly sand deposit, see test hole
Appendix A.
throughout
alluvial
logs in
The organics encountered at the surface are brown~ fibrous~ very
soft and moist to saturated. This layer supports a thick crop of
trees as described in the introduction.
Ground water was encountered beneath the organic mat on holes 3
through 6 and most likely would have been encountered at holes 1
and 2. At the lower elevations represented by holes 7 through
20, no ground water was encountered. This leads the engineer to
believe that the water at the higher elevations is perched and
held up by a dense material located at a lower elevation. This
area is located on a bench and may be able to be drained, see
Recommendations and Conclusions.
The sands and gravels located beneath the organic mat is very
clean and contains an occasional coble. Most of the gravel is 1
to 2 inches in maximum size, and could be used as a NFS gr~vel
source for developing roads and ~oundations.
The various types of soils are indicated as well as the depths
where the soils or characteristic of the soils changed in Appen-
dix A. It should be noted that these changes are gradual and can
be interpreted between the test holes.
FOUNDATION AND SEPTIC SYSTEM ANALYSIS
It is understood that the proposed development of the site will
consist of wood framed single family dwellings. The material is
well suited to support standard wall foundations with footings.
]'he bearing capacity of the soil exceeds 6000 psf for a design
value; however, this material must be compacted to a dense.state
directly under the footings to prohibit settlement.
Caution should be taken whenever trenchs are excavated though the
subsurface material to prevent collapse of the walls~ since this
material will sluff readily.
It is also understood that. each lot will have its own septic
system. Again the material encountered in the 4 to 12 foot depth
is well suited for septic disposal. This material is a sandy
gravel classified as a well graded gravel (GW) and would have a
perculation rate exceeding 2 minutes per inch. The Municipality
of Anchorage rates this material for septic permits at 85 square
feet per bedroom. It is however suggested that each lot be
tested in the location of its proposed septic system to insure
the consistence of the soil.
The area of the site with the ground water encountered at or just
below the surface is not acceptable at this time for foundations
or septic systems. If the area were to be drained, the soils
would be also suitable for construction once consolidation of the
material was accomplished by means of compaction.
CONCLUSIONS AND RECOMMENDATIONS
In summary, the soils at the proposed subdivisioin sits are wsll
suited for residentual construction of housss and septic systsms
in tbs arsas not sncountering high ground watsr.
The areas with the high ground water can possibly be improvsd by
draining the water to a dspth of 12 fsst bslow the surface. This
can. be accomplished by wells, drainage ditches, or perforated
drainage pipes.
It is rscommendsd that the Subdivision be divided into two Phases
inorder to construct on the arsas presently suitabls for
dwellings. Phass I would be the lowsr area not sxpsrisncing high
ground watsr but vsry good soils conditions suitabls for building
foundations and ssptic systems. Phase II would be the arsa
directly so'th of Phass I and has very good soils also, but the
high water tabls prsvsnts any development at this rims.
As mentioned earlier there are many ways of dewatering an area so
that it cao be used in the future. It appears that the most
economical and. safest method will be accomplished by the means of
a subsurface drainage structure. Both filter fabrics and
perforated pipes were analysised and it is -felt that a
combination of both will be considered for the project of
dewatering the Phase II area.
To begin the dewatering process, trenches would be excavated
starting at the lower elevation of the pipe profile, as
determined by the topography of the area, and proceeding into the
marshy lots. This will help keep the trench fcee from high
levels of water fo that the pipe can be installed without
excessive pumping, and may successfully drain the~area if the
impermiable layer is cut, Allowing free drainage. It is
anticapited that a 12-18 inch perforated CMP Culvert will be
installed to intercept any water or future water above the
profile of the pipe, and filter fabric will be wrapped around the
pipe if silty material is encountered. The profile will be
established about 20 feet below theground surface so that areas
needing to be drained greater than 100 feet away will allow for
the installation of a septic system. This means that the water
table must be below 123 feet as a minimum.
The drainage system will enter the Phase I porition of the
subdivision with a nonperforated pipe and will dump the collected
water into the railroad ditch for transportation by nature
drainage to the inlet as provided by the Alaska Railroad R.O.W.
Its is mosst desireable that as much of the total drainage system
be located within the road R.O.W's as possible. This will keep
the amount of cleaPing to a minimum and prov;ide for maintenance
if necessary.
The proposed system location is provided on blueline prints of
the subdivision and is submitted for approval for lateral
-clearances. Additional in formation will be needed for exact
distances and elevations for the final design and will be
obtained at the time the lots are Surveyed. Wells will. be
located throughout the Phase II area to monitor the draw down of
the water.
The recommendations of this report are based on the assumption
that soil conditions do not deviate ~rom those disclosed in the
test holes. If any variations or undesirable conditions are
encountered during development, we should be notified so that
supplemental recommendations can be furnished.
