Subject: Overlook Estates #2,Lot 2
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 3-bedroom home on the property. We are submitting
this design and permit application for the construction of a new well and septic system. The
attached site plan identifies the location of the home and the proposed well location,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 to the west,at an approximate 20%slope. There are no slopes
steeper than 25%within 50' down slope of the proposed absorption trenches. Ground contours are
shown on the site plan showing the grade and direction of flow. Storm water drainage will not
impact this septic system. The new trench will be constructed parallel to the slope as much as
possible.
Test holes on the lot and in the subdivision indicate very coarse gap graded gravel with very few
fines. The absorption rate of effluent is much faster than 1 minute per inch. A 2' sand liner is
required and has been designed in to the system.
Wells on this and adjacent lots are shown. The new system 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 6' away from the primary site.
Please refer to the attached test hole logs, soils lab analysis, plan and profile sheets for the septic
design. If this design is followed, there will be no adverse impacts to adjacent properties.
Sincerely, 44.loOF 4!" .

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 11/01/2023
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 &
