All construction shall be in accordance with:
1. The attached approved design.
2. All requirements specified in Anchorage Municipal code Chapters 15.55 and 15.65 and the State of Alaska
Wastewater Disposal Regulations (18AAC72) and Drinking Water Regulations (18AAC80)
3. The wastewater code requires inspections during the installation. The engineer shall notify the Development
Services Department per AMC 15.65. Provide notification by calling (907) 343-7904 (24/7).
4. From October 15 to April 15, a subsurface soil absorption system under construction during freezing weather
shall be either:
a. Opened and Closed on the same day, or
b. Covered, sealed, and heated to prevent freezing
Special Provisions:
If trench length becomes a single length, then a test hole is required prior to construction of the absorption field,
in the location shown on the site plan, to confirm minimum separation to impermeable soil and seasonal high
groundwater, as well as percolation rate. Construction may proceed at your own risk prior to 7-day groundwater
monitoring. If results require a design change, construction shall stop pending approval of a change order.
Please submit results with the inspection report (or change order, if required).

Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends has a 4-bedroom septic system that is on the verge of failure,
so we are submitting this permit application for a new septic system . The attached site plan
identifies the location of the home as well as the existing well, and septic location. No conflicts
exist between this proposed system and any other well or system, whether on this lot or adjacent
lots.
The ground surface on the lot is generally flat, with some steep slopes to the southeast. The new
septic system will be located just outside the well radius. (Please note that there are some slopes
greater than 25% closer the 50 feet downslope of the primary site; a slopes profile is attached for
your reference.) The site plan indicates the grade and flow direction via contours. We anticipate
no impact from stormwater drainage on this septic system. The new trench will be constructed as
parallel to the slope as feasible.
Although wells on this and adjacent lots are not within the immediate viewing port, they have been
visually located to ensure no impact on the proposed system. The new system will maintain a
minimum distance of 100 feet from all wells and surface water, and more than 5 feet from the
septic tank itself. Please refer to the attached test hole log, plan, and profile pages for the septic
design. If this design is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Benjamin Schiller, PE

(3) wells must be adequately protected against flooding;
(4) if there is an annular open space outside the well casing,
it must be filled with a watertight cement grout,~ sealing clay, bento-
nite, or equivalent material to a minimum depth Of l0 feet below the
ground surface;
(5) the surface, for l0 feet in all directions around the
well, must be sloped or contoured to drain around or away from the
well; when, in the department's opinion, there is a potential for a well
to become contaminated by surface water, the department, in its discretion,
will require~the provision of an impervious surface, extending at least
two feet in all directions from the well;
(6) a drain pipe from a well honse to a sewerage system is
prohibited; and
(7) newly constructed or reworked wells must be flushed of
sediment and disinfected before use.
(c) A person who owns or is responsible for any well, abandoned or
not in use; any hole, either drilled, augered, or Jetted for tbe purpose
of subsurface exploration or sampling; any cathodic protection well, or
any other form of excavation, which may cause contamination of a water
system, shall seal, protect, or fill up the well, hole or excavation
using methods approved by the department.
........ (d) No person may construct install, maintain, or operate a public
water system unless the mimimum separation distances in Table A, measured
horizontally in feet, are maintained between the public water system
seurce and the potential sonrce of contamination. When the department
determines that local soil conditions, groundwater conditions, snrface
topography, geologic conditions or other conditions indicate that the
separation distances in Table A will not provide adequate protection
against contamination of a water source, the department will require
greater separation distances. A person may request: approval from the
department for separation distances-less than those specified in Table A,
but in no case will a distance less than 100 feet be allowed between a
water source and a wastewater treatment and disposal system, a °~ewage
pump station, a sewer main cleanout, or a sewer line manhole. ~Any.person
requesting approval of a separation distanc~ less than specified j.n'~ ~
Ta~l~ A must S~bmit a repbrt prePare~ signed and s~aleH by a pr0f~ssional
engineer registered ia the State of Ataslca in accordance with AS 08.48.221,
which Justifies the lesser separation distance. The ~ustification must
include consideration of soil conditions, groundwater conditions,, surface
topography, geologic conditions and any other conditions of importance
Reg. 67, Oct'., 1978
TITLE 18.
ENVIRONMENTAL CONSERVATION
in establishing the separation distance. If the department finds that,
due to local soil conditions, groundwater conditions, surface topography,
geologic conditions and any other conditions, the separation distances
in Table A are clearly not necessary to prevent contamination of a wate~
source, the department will, in its discretion, allow lesser separation
distances which, in its opinion, are necessary to prevent contamintion
of a water source. If the department allows tesse~r separation dis6ances,
the owner and operator are not relieved of the responsibility to meet
the maximum contaminant concentrations astablished in sec. 50 of this
chapter.

Conditional COSA request
Dear On-Site Services Engineer:
The owners of the above lot started the process of testing their septic system in late June, but there
were several deficiencies noted – pipes missing and broken, and an older tank located in the well
radius. We moved forward with a full septic replacement permit and were able to get approval for
that on Sept 2. While we were not able to take measurements in the trench due to the broken
monitoring tube, the system has not backed up into the tank, there are no smells in the yard or soft
spots in the soil, and there has been no daylighting of effluent. The water sample from the well
had no nitrates in the water. For the time being there is no contamination from the system and it
continues to be operable for the occupants.
However, in the meantime they had several offers on their property and a buyer that wanted to
close immediately. With contractors being busy near the end of the season, most contractors were
several weeks out at least for installing the system. The buyers have collected 3 estimates and the
attached letter noting that 150% of the highest bid will be placed in escrow to be released when
the project has been installed. We anticipate an installation date prior to Oct 15.
We request a Conditional COSA be issued to allow for the sale of the home, with the work to be
done as soon as can be scheduled with a contractor.
Thank you,
Benjamin Schiller, PE
To On-Site,
Subject: Conditional COSA for Meghan Dotten and Quinlan Patrick-Harris - 14901 Wildien Drive
Anchorage, AK 99516
An escrow holdback in the amount of $88,976.00 ($44,480.00 at 200%) is to be established at closing.
Funds will be used for the work required: Septic tank to be relocated outside of well radius. Septic system replacement similar to current system with 1250 gallon poly tank. Install 120' FT 5' wide drain field with .5" effective layer of 2' MOA sand filter.
The money shall be held by the lender until such time as a final unconditional certificate of On-Site
Systems Approval is issued by the On-Site Water and Wastewater Section.
