Subject: Initial Well and Septic Permit - Sampson Estates Block 2, Lot 4
The owner has requested we proceed forward to obtain a well and septic permit
for a new residence on the subject lot. The general slope of this lot is
approximately flat (0-2%) over the septic area.
On June 30, 2011 two testholes were performed to investigate soils and
groundwater. The results of these tests are attached for your review. The
proposed septic system will serve a new 4 -bedroom house. We propose to install
two 56' long deep trenches. Groundwater was not encountered during
excavation or at monitoring.
The adjacent lots are served by community water and there are no wells within
200' of the proposed system and the proposed well on this lot is not within 100
feet. There is no surface water within 100' of the proposed system and there are
no known curtain drains within 50'. We do not expect there to be any adverse
effect on adjacent lots by the development of this system. If you have any
questions, please contact me at 696-6111/FAX 868-3793.

Subject: CHANGE ORDER to Well & Septic Permit # OSP111194
Sampson Estates Block 2 Lot 4
Jay:
The owner has requested we modify ouroriginal design for the septic system
permitted on the subject lot to serve a proposed 5 -bedroom house. The proposed
building elevation also makes it necessary to install a STEP tank six feet below
the original grade and pressurize the drain field. Both components have been
redesigned to accommodate the additional bedroom that is being added to the
proposed structure.
The drainfield and septic tank remain in the vicinity of the originally permitted
design and an additional test hole will be dug to insure consistant soil conditions
prior to construction, and as such, do not pose any significant change to the
current permit.
There are no public or private wells within 200' of our proposed system location
except as noted. There is no surface water within 100' of the proposed system
and there are no known curtain drains within 50'. We do not expect there to be
any adverse effect on adjacent lots by the development of this system. If you
have any questions, please contact me at 696-6111 / FAX 696-8111.

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION PRACTICES AND MATERIAL SPECIFICATIONS
LEGAL DESCRIPTION: Sampson Estates Block 2 Lot 4
GENERAL:
1. The scope of this project includes the installation of a septic tank and/or
drainfield to serve a single-family residence on the referenced property as
delineated on the attached Municipality of Anchorage (MOA) permit and site
plan. Construction shall be in accordance with the approved site plan and
design drawings; MOA permit with any special provisions or conditions, and all
applicable State and Municipal Wastewater Disposal Regulations.
2. ArcTerra Engineering & Surveying, Inc. (ArcTerra) assumes no responsibility of
the accuracy of the as -built survey provided by the owner or owner's
representative.
3. The owner or contractor is responsible to notify the engineer of any
discrepancies noted on the design plans or drawings prior to commencing work.
These discrepancies could be, but not limited to, possible encroachments, surface
water, varying soils, unplatted easements, types or use of dwellings on or
adjacent to property, nearby public wells, etc.
4. The contractor shall be responsible for locating any necessary underground
utilities, easements, property lines and surface water. The owner and/or
contractor shall ensure, if deemed appropriate, that a registered land surveyor
prior to construction flags all setbacks. The contractor shall be responsible for
verifying all pertinent separation distances and component layout.
5. Unless specifically agreed otherwise, the property owner shall be responsible for
final grading areas subsequently depressed from soil settling. On all leachfield
mound systems, the property owner shall be responsible for ensuring a
satisfactory vegetation growth over the mounded area.
6. The MOA Development Services Department On -Site Water & Wastewater
Program must certify contractors installing wastewater disposal systems.
Owners installing their own systems must also receive prior approval from said
MOA Department.
SEPTIC TANK/ HOLDING TANK/ LIFT STATION INSTALLATION:
1. A septic tank is to be constructed by a certified septic tank manufacturer.
Construction shall include two 4" cleanouts for pumping access.
2. The septic tank shall be sufficiently bedded with proper material and
compacting to prevent damaging, settling or shifting of the tank.
3. All standpipes on the septic tank shall extend a minimum of 12 inches above the
final grade.
Sampson Estates Blk 2 Lot 4
August 5, 2011
Page 2 of 4
4. Septic tanks installed with less than 4 foot of cover shall be insulated. The
contractor will ensure that the fill over the tank does not exceed the burial depth
rating.
5. A foundation cleanout shall be installed one to four feet from the building
foundation. In the line between the tank and the leachfield there shall be two
adjacent cleanouts (unless an effluent pumping system exists within the septic
tank). These cleanouts shall be located on undisturbed soil not more than 10 feet
from the tank. The second cleanout, in line, shall be to clean toward the septic
tank.
6. Final grading over the septic tank shall be such that a positive slope exists away
from the septic tank.
7. All H.D.P.E. tanks shall have a vertical length of 4 -inch perforated drainpipe
besides the tank extending to the bottom of the tank to above grade to monitor
ground water.
8. All tanks shall be anchored when there is not enough adequate soil cover to
resist buoyancy forces in high -groundwater areas.
9. All holding tanks and lift stations shall have an audible and visual alarm inside
the residence.
10. All lift stations shall be wired in compliance with the Uniform Electrical Code
and all MOA guidelines.
11. The contractor shall remove the old tank, or abandon it in compliance with the
Uniform Plumbing Code. The contractor is solely responsible for the
abandonment procedure.
ABSORPTION TRENCH/DRAINFIELD INSTALLATION:
1. Excavate the proposed trench to the dimensions shown on the design. The
bottom of the excavation shall be within 2 inches of level. If the sidewalls of the
excavaction become smeared, they must be raked or scratched (roughed -up)
before gravel (sewer rock) placement.
2. Once the sewer rock is installed, the distribution pipe is installed level with the
perforations facing downward. Gravel is then to be placed over the distribution
pipe to provide a minimum of 2 inches of cover over the pipe.
3. A silt barrier must be installed between the final gravel layer and the native soil
backfill. Ensure the silt barrier covers the entire gravel surface before placing
backfill.
4. Monitoring tubes shall be four- (4) inch diameter, installed approximately in the
locations shown on the design, and extend a minimum of 12 inches above final
grade. The portion of the monitoring tube extending through the gravel shall be
perforated from the bottom of the trench to the invert of the distribution pipe.
This is equivalent to the effective depth of the gravel as noted on the design.
5. Backfill over the final gravel layer must not be less than twenty-four inches.
Insulation must be installed when the backfill depth is less than thirty-six (36)
inches. The finish grade over the trench must be mounded to prevent the
formation of a depression after settling.
6. All advanced technology waste water disposal systems (Advantex, Biocycle,
Intermittent Dosing Sand Filter, etc...) shall be constructed, installed, maintained
and monitored per manufacturer's specifications and MOA requirements.

MINIMUM MATERIAL SPECIFICATIONS:
1. A MOA approved septic tank manufacturer must construct any septic tank
proposed for installation.
2. The following pipe materials are MOA approved for use in septic system
installations:
Type of Pipe Perforated Solid
Cast Iron Yes Yes
ASTM D3034 (PVC) Yes Yes
ASTM F810 (HDPE) Yes No
ASTM D2662 (ABS) Yes Yes
3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow
Chemical Company Styrofoam HI or equal).
4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder,
Fernco, or equal).
5. A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be
installed between the final leachfield gravel layer and the native soil backfill.
6. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less
than 3% passing the #200 sieve. If deemed necessary, a sieve analysis should be
performed.
7. When sand is being used as a filter material, its gradation specification must
conform to current MOA or ADEC requirements.
INSPECTIONS:
Typically there will be three (3) inspections required during the installation of the
wastewater disposal system. These inspections will occur as follows:
1. The first inspection must be conducted after the excavation of ditches, pits,
trenches, or beds and before the installation of any gravel. A septic tank may be
set in place, but may not be backfilled before this inspection.
2. The second inspection must be conducted after the placement of the sewer rock,
distribution lines, standpipes, and cleanouts, but before the placement of the silt
barrier, insulation, or any other backfill.
3. The final inspection is to occur upon final grading of the property.
Often there will be more than these 3 inspections required, especially with the
installation of multiple trenches, sand filters, pressurized distribution systems, etc. The
inspecting engineer is to be contacted at least 24 hours prior to the start of construction.
If necessary, a pre -construction meeting will take place on-site. The inspecting engineer
will not coordinate, direct or control in any way the contractor's activities.
The owner shall contract with the contractor to perform the work outlined in these
specifications and attached plans and in accordance with the attached MOA permit. All
materials, components, and construction practices shall comply with the MOA's and the
State of Alaska's latest ordinances, regulations, or policies regarding wells and septic
systems. The failure of the inspecting engineer to notice a material or construction non-
compliance does not relieve the contractor of his/her responsibility to correct such
deficiency. There will be no contractual arrangement existing between the contractor

and ArcTerra. ArcTerra shall be the owner's representative and will inspect the work as
stated above to document the contractor's activities. Final acceptance of the contractor's
work rests with the owner and the MOA.
ArcTerra shall have no liability to the owner or to others for acts or omissions of the
contractor or any other persons performing work on this project or the failure of the
contractor to carry out the work in accordance with these construction documents.
ArcTerra's inspecting engineer will not be responsible for the construction means,
methods, and techniques, sequence, procedures or the safety precautions incident to this
project.

Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. The assessment of the condition
of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface
conditions that may not be observed from the surface, changes inland use, local soil characteristics, groundwater levels that may fluctuate
during the year and the water usage of the family being served by the system. The operational life of all well and septic systems are
subject to these various and dynamic characteristics and are outside the control of the
evaluator of the well and septic system. Therefore,
ArcTerra can not give any estimate of how long a
system will function satisfactory for current or future*Aoccupants or can ArcTerra guarantee that no unseen �"' Cly' 4�
encroachments, deficiencies or discrepancies exist. '' � , -
