RE: T15N R1W Sec 30 Lot 52C – Septic System Upgrade
A permit is requested to replace a septic tank and soil absorption system for the subject property. The
proposed system will serve an existing 6-bedroom, multi-family home (duplex). Note the Municipality of
Anchorage (MOA) property search record indicates the subject property is a 7-bedroom structure. The
property owner states there are 6 bedrooms and an office. This design is for a 6-bedroom structure.
Wells
The subject property is served by an existing private water well. Neighboring parcels are served by private
water wells. There are no wells within 100’ of the designed septic system.
Soils
AK Built Construction & Design, LLC (AK Built) observed a test hole, performed a percolation test, and
groundwater monitoring on December 9th, 2024. Soils are classified as silty sand with gravel with cobbles.
Groundwater was not encountered in TH-01 (12’ BGS). Groundwater was not observed at least seven (7)
days later. The percolation rate in TH-01 was faster than 1 minute per inch. An application rate of 1.2
gallons/day/square feet shall be used for a conventional wastewater system.
Wastewater disposal systems
The designed wastewater disposal system is a wide trench system with 30” of sewer rock below the pipe
invert. The designed system has the following characteristics.
# Bedrooms: 6
Daily Design Flow: 900 gallons/day
Tank Size: 1,750 gallons minimum (Design is for a 1,250-gal and 1,000-gal in series)
Percolation Rate: 0.27 minutes/inch
Soil Rating: 1.2 gallons/day/square feet
Field Area Required: 750 square feet
System Type: Wide Trench
Width: 5 feet
Minimum Length: 95.45 feet
Designed Length: 100 feet
Designed Field Area: 785 square feet
Maximum Excavation Depth (from existing ground) Allowed: 6 feet
Existing disposal site
The existing disposal site located on the subject parcel is assumed to be a trench system as identified in
historical records. One field monitor tube was located at what is assumed to be the end of the trench

system. Neighboring parcels with existing disposal sites do not impact the subject parcel and the proposed
system will not negatively impact neighboring parcels.
Drainage
There is no surface water located within 100’ of the designed system.
Topography
The designed system is centrally located along the east-west orientation of the property and slightly south
of center along the north-south orientation of the property. The surrounding property slopes up-gradient
to the northeast, gently slopes down-gradient to the southeast, and slopes down-gradient to the west.
Steep slopes exist in the vicinity of the designed system, as shown in the plans. The proposed wide trench
system is installed on a slope less than forty-six percent. A portion of the designed wide trench system is
installed on slopes more than twenty-five percent thus steep slope provisions apply. The maximum
excavation depth shall be applied by measuring from the up-gradient side of the disposal field. Width of
the wide trench system does not exceed sixty inches. The natural vegetation within fifty feet down-
gradient of the disposal field shall remain undisturbed. The proposed distribution pipe invert is less than
thirty-six inches below the top of the natural organic layer as measured on the downhill side of the
excavation but there is no anticipated daylighting effluent down-gradient of the disposal field. The
proposed system’s ‘watershed’ is to the southeast where slopes are primarily less than twenty-five
percent. See attached figure for watershed delineation and anticipated flow direction. Final grading of the
wide trench system shall be at a slope not greater than a 3H:1V (33%).
The designed system does not have probable adverse impacts to adjacent properties.
If you have any questions, please contact me.

RE: T15N R1W SEC 30 LOT 52C – 15712 MOOSEBERRY BEND, EAGLE RIVER, ALASKA
ON-SITE WATER & WASTEWATER SYSTEMS REPORT
Per your request, we have inspected the on-site water and wastewater systems of the above referenced 6-
bedroom property. This investigation was based on observations of the day in which the septic adequacy
and well flow inspections / tests were performed and according to the available and attached Municipality
of Anchorage (MOA) record documents. This is to certify that as of the date of this letter, the subject on-
site well appears to meet or exceed minimum state requirements pertaining to water production and water
quality for coli, arsenic and nitrates. However, this 41-year-old 1983 installed septic system (tank &
absorption field) is totally saturated and the 6-bedroom duplex residence wastewater system will need to
be completely upgraded.
The septic absorption field constructed in 1983 consists of a steel 1750-gallon steel septic tank and a 51’
long, 5’ effective depth / sewer rock absorption trench installed in fast percolating gravely rated soils of
85 SF/BR. This soil rating is not applicable to current code design and most likely will require a sand
filter if these types of soils are encountered with excavation. The aged steel septic tank is extremely old
and upon arrival there was no cap on the absorption field with the effluent fluid levels above grade.
Effluent could freely flow to the surface and create a biohazard from the condition of the field. The septic
system needs to be replaced.
We have contacted Northern Excavation on rough cost estimate for a hypothetical septic upgrade which is
attached. However, to obtain a more precise cost estimate we would need to conduct test holes with soils
percolation, groundwater monitoring, a design, MOA permitting review followed by install bid requests,
construction inspections, final documents along with a final survey, etc… to upgrade this septic system.
One could roughly budget $10,000.00 for these engineering, surveying and MOA costs and these costs do
not include the actual install costs which Northern Excavation has roughly provided.

Prior to commencing the well flow test, the static water level was measured at 232’ from the top of
casing. The wellhead consists of 6” steel casing extending 2’ above grade with a broken sanitary sea, no
bolts, or conduit. These items need to be corrected and would recommend Sullivan Water Wells. The well
produced 3 gallons per minute (GPM). Coli, Arsenic & Nitrate (CAN) water samples were drawn and
submitted to the lab for analysis. The results of this water analysis show that the water meets state and
municipal safe drinking water standards for this CAN analysis currently.
The assessment of the condition of the well and septic applies only to the conditions as of the day tested.
The absorption and flow rates may change due to subsurface conditions that may not be observed from
the surface, changes in land 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 is subject to these various and dynamic characteristics
and are outside the control of the evaluator of the septic system. Therefore, we cannot give any estimate
of how long a system will function satisfactory for current or future occupants or can we guarantee that
no unseen encroachments, deficiencies or discrepancies exist.
If after review of these records, you or any of the underwriters have any questions regarding the adequacy
of these systems or the methods employed during our inspection please feel free to contact us at (907-
350-9566) or via email at FirstWaterAK@gmail.com.
Respectfully,
Curtis Huffman, P.E.

We have reviewed the plans and specifications for the subject project.
More information is needed before final approval is considered:
1. A flow test showing drawdown and recovery rates.
2. Storage calculations must account for real storage for WX 252
tanks, which is somewhat less than 87 gallons.

Dear Sir:
Subject: Lot 52B, Section 30, T15N, R1W, Wastewater System
Chugiak, Alaska (8421-DA-347)
We have reviewed the plans and specifications for the subject project.
The plans are approved, conditioned on adherence to the following items:
1. screened rock back fill in deep and wide trenches (3/4" - 3").
2. screened rock back fill in absorption bed (3/4"- 1 1/2").
3. sufficient area plotted on as-built for replacement system.
This letter constitutes the permit required by A.S. 46.03.720(a) for
plan approval of sewerage systems.
It should be remembered that final approval will necessitate the submission
of Engineer As-built Plans to include photographs as iHdicated on page 13
of enclosure. This will consequently mandate that a pro~essional engineer
conduct basic inspection of this project so as to be able to sign off on
as-built plans. Arrangement for this inspection work is the responsibility
of the developer.
