Septic System Design and Permit Application -.
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The existing septic tank on Lot 2A, Block 1, Pennington Park' Subdivision has collapsed
and must be replaced immediately to prevent damage to private property and a
possible health hazard. We are therefore requesting a permit be issued to construct a
new septic tank at the location shown. The attached Site Plan and backup
documentation show the location and configuration of the new septic tank and 'its
proximity to the existing lift station and absorption bed. -It also shows the 100'
protective radius for the existing well on the lot. The septic tank will be moved out of
the parking and driveway area and the existing tank will either be pumped, crushed and
backfllled on site or removed from the lot. The existing service line will be insulated
under the driveway/parking area.
The septic system absorption bed was upgraded In .1991, but the tank was not
replaced.. Records Indicate an as-built for the bed upgrade was not submitted to the
Municipality. We will attempt to as-built the absorption bed at this time and submit the
documentation along with the as-built for the septic tank. The owner intends to install a
1,250 gallon septic tank even though t,h,e house currently has only.three bedrooms.
The additional capacity of the tank wdl'enhance the treatment capabilities of the
upgraded septic system.
The existing drainage on the lot will not be affected by the placement of the new septic,
tank. Cleanouts .w. ill be placed as necessary to allow access to all portio.n.s of the septic
system. The lot is of sufficient size that no conflicts will exist between e~ther the well or.
septic system on the lot and all other systems in the area. :.
If the system is constructed '~n accordance with our.design the following statements
apply:
1. The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse '~mpact on existing.
septic systems In the area or those to be'constructed in the future.
Fot 2A, Block 1, Pennington Park Subdivision
May 15, 2000

The system, if constructed as designed, will have no adverse impact on reserved.
space, either surface or subsurface, on any lots located in the area.
The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincerely,

new 1,250 gallon septic tank. It also includes the pumping, crushing
and backfilling of the existing septic tank. T. he existing tank may a. ls.o
be removed from the lot and the remaining cavity appropriately
backfilled. New cleanouts must be placed to provide access to all
components of the upgraded septic system.
Construction shall be in accorda,n, ce with the approved s. it,e plan,
design drawings, Municipal Permit with any special provisions or
conditions, and all applicable State and Municipal Wastewater
Disposal Regulations.
The Contractor shall be responsible for obtaining all underground utility

location of all lot lines.
Unless specifically agreed otherwise, the contractor shall be
responsible for final grading areas subsequently depressed from soil
settling. Property owner shall be responsible for revegetation of
affected areas unless specifically agreed otherwise.
Contractors installing wastewater disposal systems must be certified
by the Municipal Department of Health and Human Services for
system installations. Owners installing their own systems must receive
pdor approval fram D.H.H.S. before beginning system installation.
SEPTIC TANK INSTALLATION
1. The new 1,250 gallon septic tank must be procured from an approved
source and installed at the location shown on the plans.
2. A septic tank is to be constructed by a certified septic tank
manufacturer. Construction shall include two 4" cleanouts for pumping
access.
The septic tank shall be sufficiently bedded to prevent settling or
shifting of the tank.
All standpipes on the septic tank shall extend a minimum of 12 inches
above final grade.
Tanks installed without 4' of cover shall have a minimum of 2" of direct

less than 3' of backfill depth is available. Finish grade over the trench
must be mounded to prevent settlement or depressions.
7. Grade area surrounding the absorption trenches to drain away.
A minimum 2' of accepting soil is required below the drainfield rock for
a 5' wide trench. Contractor shall verify this condition prior to
placement of the rock. All pockets of unacceptable materials must be
removed and replaced.
MATERIAL SPECIFIC/~TIONS:

SYSTEM REPLACEMENT
System Size = 3 bedrooms x 300 sf/bed. = 900 sf
Pressure Distribution Absorption Bed = 15' x 60' = 900 sf
Ail materials, construction methods and required inspections
to follow MOA rules and regulations. The electrical
installation for the lift station shall follow MOA code
requirements for both installation and inspections. The
contractor is responsible for obtaining all required
electrical permits. The contractor is responsible for
notifying the Engineer and the MOA at least four hours in
advance of all inspection needs.
Contractor will insure no additions or changes have been
made to the location of wells and septic systems on the

system. If any changes to those systems have occurred, the
engineer should be immediately contacted for review and
possible changes will be made as necessary.
The OB/Fill material will be removed tO the underl¥igg
gravelly sand material under any portion of the bed area~
The lot is generally flat with a slight 2 - 5% slope along
thew north property line and a 15 - 20% slope along the west
property line. The installation of the system will have
little or no effect on the surface drainage, ground water,
or the adjacent systems in the area.
The septic system should be properly maintained to include
septic tank inspection and pumping as necessary on an annual
basis and no use of a garbage disposal. The existing tank
should be inspected for deterioration at the time of new
sysem installation. If found to be deteriorated beyond
normal levels, the tank should be replaced. If a garbage
disposal is used the tank size should be increased to a
minimum 1,250 gal tank and the tank pumped regularly on an
annual basis.

Percolation Test, Lot 2A, Block. !
Pennington Park Subdivision
Gentlemen:
At your request, we have completed a percolation test on Lot 2A,
Block 1~ Pennington Park Subdivision in the hillside area of
Anchorage. The boring location is shown on Figure 1. It was
drilled using a continuous flight solid stem auger, advanced by a
Simco, drill rig mounted on the back of a truck. The rig is owned
and is operated by Denali Drilling, Inc. Drilling was supervised,
the test hole logged and percolation test performed by Mr. O. M.
Hatch, Alaska Testlab geologist.
The log of the test hole is included as .~_9~b_t_e_.A~of this report.
In interpreting the log, it would be helpful to utilize the explana-
tory information contained on Sheets 5, 6 and 7 of the report.
When drilling was completed, a 3/4" slotted PVC pipe was inserted
in the hole to ai_d in determining the free water level. For the
percolation test, the test hole was filled with water and left
overnight to saturate. On returning the next day, the hole was
refilled with water and the water level carefully monitored for
the next 60 minutes.
This procedure is not a standardized percolation test, however, we
understand the Municipality of Anchorage, Department of Health and
Environmental P];o'tection,. accepts tests performed in thi. s manner
to evaluate the sit. e for' proposed onsite sewerage system.
Us'lng the above test, the observed minimum percolation rate for a
ten minute peri.od was 10.0 minutes per inch. We suggest that the
onsite wastewatcr system be desJ. gned for a minimum absorptien area
of 165 square feet per bedroom. This recommendation i.s based on
criteria in the "}!anua! of Septic Tank Practice" U.S. Department
of Health E(]ucatien and Welfare, Public Health Service.

We recommend the absorption trenches be inspected prior to installing
the system as the above reconunendations are based on the result of
one six-inch test hole. The seepage trench will provide a much
clearer picture of the subsurface conditions than the test. hole.
If the soil conditions turn out to be more favorable than predicted,
it may ]De possible to economize the system by reducing the length
of the trench. Conversely, if' the soil appears less permeable
than the test indi'cates, then it may be necessary to enlarge the
system. The chief value of the drill hole is in establishing the
feasibility of onsite systems, while examination of the trench
will provide site specific information. The following items are
