Septic system design and permit application
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-bedroom home on the property, so we are
submitting this permit application for the construction of a new well and septic system. The
attached site plan identifies the location of the home as well as the proposed well. septic location
and alternate site. No conflicts exist between this proposed system and any other well or septic
system,whether on this lot or adjacent lots.
The ground surface on the lot slopes toward southwest at slopes less than 25%. It is in that
flatter area that the new septic system is located. There are no slopes greater than 25% within 50
feet downslope of either the primary or alternate site. Ground surface contours are shown on the
site plan showing the grade and direction of flow. Stormwater drainage will not impact this
septic system.
The new trench will be constructed parallel to the slope as much as possible. It will be a
minimum of 100' from all wells and surface water, and more than 5' away from the septic tank.
The alternate site is located more than 14' away.
Please refer to the attached test hole logs and plan and profile pages for the septic design. If this
design is followed,there will be no adverse impacts to adjacent properties.
Sincerely,
14,1„1

Report Type: On-Site Review Completed By: R.Carroll
The application has been reviewed and the following comments have been generated. These are to be satisfactorily
addressed prior to MOA approval:
1. Submit plot plan (AMC 15.65.050D.1).
2. Test holes are not deep enough to demonstrate separation to impermeables or ground water(taking seasonal
adjustment of 1 foot into account). Please address.
1. The plot plan is attached.
2. Recent observations indicate the test hole remain dry as of May 6 or slightly more than 1 week from II
accepted date for high groundwater observations. We are confident the test holes will remain dry througl
that period and will provide documentation to demonstrate our conclusions. The test holes will also be
excavated to a depth of 16' prior to construction to verify the lack of an impermeable layer. The results o
the test hole excavation will be submitted for your review. We request a special condition be added to th
permit requiring the test holes be extended to a minimum depth of 16' prior to construction.

F. ENGINEER’S COMMENTS
G. CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER
As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based
on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water
supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes,
ordinances, and regulations in effect at the time of installation, unless noted otherwise.
Name of Firm FIRST WATER CONSULTING Phone 907-350-9566
Engineer’s Printed Name CURTIS HUFFMAN, PE Date 6/10/23
Comments: This investigation was completed in compliance with MOA guidelines, regulations,
and best industry practices / methods. 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 in land use,
local soil characteristics, groundwater levels that may fluctuate during the year, quality of
construction (workmanship & materials), the water usage of the family being served by the
system and maintenance. 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, any or NO estimate of how long a system will function satisfactory
for current or future occupants or guarantee that no unseen encroachments, deficiencies or
discrepancies exist can be given by First Water Consulting &
