No objection
S11358-1 Ward Subdivision
Information to satisfy the requirements specified by AMC 21.15, AMC
15.55 and AMC 15.65 must be submitted for each lot within this proposed
subdivision. This information must include, but may not necessarily be

1. Soils testing, percolation testing, and ground water monitoring must be
conducted to confirm the suitability for development using on-site
wastewater disposal systems. Ground water monitoring must be
conducted during high ground water season in either the fall (October) or
spring (April -May).

system sites must be identified and must meet all criteria specified in
AMC 15.65 including slope and slope setback requirements.
3. Topographical information must be submitted.
4. An aquifer test shall be conducted within the proposed subdivision.
This aquifer test shall include one pumping well and a minimum of two
observation wells. The aquifer test shall show that there is an adequate
water supply to support the proposed subdivision and the effects of the
appropriation of water to serve this subdivision on surrounding properties.
The aquifer test shall be accomplished according to procedures outlined by
this department.

5. A nitrate model or engineer's report shall be submitted showing that the
development of this subdivision will have no adverse affects on the
existing wells serving the surrounding properties.

Mr. Roth,
Please note that public water will be extended to the project. Plans have been submitted to
AWWU for review and approval is expected within the next several days.
We request that you acknowledge the proposed water extension by signing below. This will
allow the final plat process to proceed. If you have any questions, or need additional
information, please call.

Attention: Dan Roth
Subject: Proposed Johnston Subdivision
Subsurface Soils Study
Septic System Feasibility Study
Dear Dan:
Test holes were placed on 9 lots in the proposed Johnston Subdivision during the period from
February 16 through February 18, 2005. The purpose of the test holes was to assess the
underlying soil conditions and to determine whether septic systems could be placed on the
lots to serve single-family homes. The test holes were placed to depths from 18' to 20'
utilizing a tracked backhoe operated by Alexander Siteworks Anchorage. An experienced
soils technician under my supervision was onsite during the excavation to log the soils
encountered and to perform percolation tests to determine the absorption characteristics of
the materials encountered. A monitor tube was placed in each hole to determine the
groundwater elevation over a period of time. All work was completed during after a heavy
winter snowfall so some difficulty was encountered with access to the proposed septic
system areas. The preliminary results for the percolation tests, soils encountered and water
monitoring are enclosed for your review. In addition, a contour map along with the location of
the test holes is also available for your information.
The Municipal orc trance governing septic systems requires either a reserve area on each lot
for septic systems or a minimum of three septic system sites designated on the final plat.
The lots will be served by the Municipal Water System so well radii will not be a factor in the
location of septic system. All sites, however, must be 100' from any surface water or water
body. No streams traverse the property and no surface water was observed over the
proposed subdivision area. Based on the percolation rates achieved during our soils study
the reserve area must be a minimum of 10,000 to 12,000 square feet. The attached drawing
shows the proposed reserve areas for each lot. The topographic map indicates none of the
surface slopes in the subdivision are greater than 25% so no setbacks from the breaks in
grade are required.

A total of 18 test holes were placed on the proposed lots. The overburden material
composed of peat or other organics ranged in depth from .5' to 1'. This material was
underlain by organic silt with some roots to depths ranging from 2' to 4.5'. Silty sand and
gravel with varying amounts of silt was then found to the bottom of each test hole. Sloughing
of the sidewalls was noted in many of the test holes due to the loose and dry nature of the
sandy soils encountered. The overall soil characteristics of the area are similar with
percolation rates for materials encountered less than 5 minutes per inch in almost every
case. In no case was a percolation rate found greater than 12 minutes per inch. Based on
our field study and water monitoring completed to date it appears each lot in this proposed
subdivision is capable of supporting an onsite septic system. We must caution, however,
that additional water monitoring should be undertaken to verify the high water levels of the
year have been observed in this area. It is our opinion that groundwater levels will not be a
factor except on the lots in this subdivision. Copies of the test hole logs, percolation tests,
test hole location map and the contour map showing the surface topography of the property
are included for your use. Please let me know if you have further questions.
Sincerely,
W E

Attention: Dave Grenier, P.E.

Waste Disposal Area
Dear Dave:
During the subsurface soils study for the septic system feasibility for Johnston
Subdivision we uncovered what appeared to be a waste disposal area on the property.
At your request we attempted to delineate the boundaries of the area and the depths to
which the material had been stockpiled. Several test holes were dug in the area. The
heavy snow cover in the area and the 3' frost depth in the area of the fill slowed work.
Nearly a day and a half was involved in the exploration of the area.
The attached site plan shows the approximate limits of the fill area. The exact limits
would require substantially more effort and may be greater than those shown on the
plan. A test hole placed in the middle of the proposed roadway cul-de-sac indicated a
depth of 8.5' to the bottom of the fill material. This material is composed of alder brush,
roots, stumps and other vegetation mixed with silty sand. The material was apparently
the result of clearing the property in the past and is unsuitable for use in the
construction of roads or other facilities on the project.
Test Hole No. 20 appears to be the center of the fill area and was apparently the low
area on the property prior to the fill activities. Our exploration indicates the volume of
the fill ranges between 2,000 and 4,000 cubic yards. The attached test hole logs and
site plan show the limits of our exploration and the materials encountered. Please
review this data and advise if you have further questions or would like to evaluate the fill
area further.
Sincerely,
Michael E. Anderson, P.E.

Road Centerline Soils Study
Preliminary Report
Dear Dave:
Two test holes were placed along centerline of the roadway proposed to serve
Johnston Subdivision. Samples were taken at various depths to determine the soils
classification and frost classification for use in the design of the structural section for the
road. Results from the laboratory analysis have yet to be received, but will be included
in the final report to be completed next week.
Soils encountered included silty soil with some organic content to a depth of 7'. A
sample of this material is currently being analyzed to determine whether the organic
content will prevent. the use of the material as structural backfill. This material was
underlain by clean poorly graded to well graded sand which appeared to be non frost
susceptible. This material was also sampled and the laboratory analysis will similarly
be presented in the final report.
The test hole ' location plan along with test hole logs are attached for your review.
Please advise if you have questions or comments for the final report.
Sincerely, �•
