REFERENCE: T15N, RIW, Section 30, NW ¼, NE ¼, NW ¼, SW ¼: Upgrade Proposal
for a Septic System Serving a Single Family Residence within the Municipality of
Anchorage (MOA).
To whom it may concern,
Per the request of the owner, we have evaluated the septic system on the referenced
property for the purpose of obtaining MOA approval. Based upon our records research,
the existing septic system is undocumented and not approved by the MOA. The septic
system is believed to have been installed in 1997 and consist of a 2000 gallon septic
tank and a deep trench type drainfield. During our site visits, it was noted that there is a
steep slope (50 to 100%) at the end of the drainfield. Per MOA requirements, the
drainfield must be 50 feet from any slope greater than 25 percent. Based upon this
information, the existing drainfield will not meet MOA requirements and must be
upgraded. We are proposing that the existing septic tank be excavated and the size and
integrity be verified. If the tank is found to be of poor integrity, we propose that a new
1250 gallon tank be installed in the same area. We are also proposing that the portion of
the existing drainfield within 35 feet from the cutbank be decommissioned in place and a
"dirt plug" be installed that would allow the remainder of the existing drainfield to be
modified and utilized. We are also proposing that a 35 foot waiver be granted from this
steep slope to the proposed drainfield upgrade. Comments regarding the design are
summarized as follows:
SOILS AND DRAINFIELD DESIGN: See the attached logs which shows the soil
classifications, groundwater monitoring, and the percolation test results. A test hole was
drilled by Discovery Drilling to determine the soil classification and depth to groundwater
or bedrock. A 22.5 foot deep test hole was drilled on 7/30/2010 and no groundwater or
bedrock was encountered. We checked the monitoring tube 10 days later and found it to
be dry. The soil was visually classified during the drilling of the test hole as a GM
material and is believed to have a percolation rate between 1 and 15 minutes/inch. See
attached design drawing for drainfield specifications. Based upon this test boring and the
elevation shots taken during one of our site visits, we are proposing that a deep trench
be excavated in the same area as the existing drainfield to a depth a 16.5 feet and then
new sewer drainrock be installed that will provide a 10 foot of effective depth. We are

Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: www.garnessengineering.com
proposing that a percolation test be performed prior to construction in order to confirm
the design parameters. A 6 to 15 minute percolation rate equates to a 0.8 gpd/sq.ft.
application rate. It is our understanding that the owner wants an approved 4 bedroom
septic system which has a design flow rate of 600 gallons per day (gpd). Based upon
this information, we will need to provide 750 sq.ft, of drainfield (600/0.8). With 10 feet
effective, the minimum drainfield length is 37.5 feet.
If the percolation rate is found to be faster than 1 minute/inch, then a 2 foot sand filter
will be required and a shallow 5-wide trench or bed type drainfield will be installed. If this
is the case, due to the limited area on the property for a septic upgrade, then an
advanced wastewater system will need to be utilized in order to provide the required
drainfield size and a reserved drainfield site. It is our opinion that this scenario is
unlikely. However, if this is found to be the case, we will contact you office immediately
and we will revise the design in order to obtain approval of the advanced wastewater
system. Per MOA requirements, a reserve drainfield site has been identified on the site
plan.
SURFACE WATERS: There are no surface waters within 100 feet of the proposed
septic system.
TOPOGRAPHY: As can be seen on the attached design drawing, the house is located
on a knoll which is flat and gradually slopes from east/northeast to west southwest. The
proposed drainfield, as shown on the design, will have an approximate 3 to 4 foot
elevation difference from one end of the drainfield to the other. We are proposing the
maximum depth of the drainfield (at the highest point) be limited to 16.5 feet to insure 6
foot separation distance to the bottom of the test hole. There is a slope that is greater
than 25 percent 35 feet down hill from the end of the proposed drainfield. We request a
35 foot waiver from the end of the proposed drainfield to this slope. The existing septic
system has been in place and in operation since 1997 and there is no indication of
effluent daylighting from the cutbank. Given the porosity of the soils, significant lateral
migration of the effluent is unlikely. The slope is heavily vegetated. Based upon this
information, we are unaware of any adverse impacts with the granting of this waiver.
CLOSING: We request a septic upgrade permit be issued at your earliest convenience
in order to expedite the installation and transaction.
We are unaware of any adverse impacts this installation would have on adjacent wells or
septic systems.~lf you have any questions, please contact us at 337-6179. Thank you
for your assis~hCe.

Engineer's Comments:
In conducting this evaluation, GEG, UD. attempted to provide a thorough, oc�o�0 p�4
conscientious engineering analysis of the system in accordance with ADEC and MOA o Q
DSD Guidelines & Regulations. The reported results described the performance of the v" �! • ' ' `'q�i0�
system under the conditions encountered at the time of the test, and separation
distances measured to readily identifiable features. The operational life of all wells and *Ti
septic systems depend on the local soils condition, groundwater levels that may • • d
fluctuate during the year, and the water usage of the family being served by the system.
These conditions are outside the control of the evaluator of the system. Satisfactory test. �`�• .l • • • • • • • • • • • • • • •0
results do not guarantee future performance of the system, nor do they guarantee that ao .• . J fr A , Ggrn ess..
there are no hidden defects or encroachments. GEG, LTD. can therefore not provide Q 9� ° E-796
any warranty or future estimate of how long the system will continue to meet the
operational requirements of the ADEC or MOA DSD. The content of this report is for ��4ed'°o\ �v
