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 10/22/2025
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 &

RE: MOUNTAIN VALLEY ESTATES BLOCK 1, LOT 17 – FIELD TO LOT LINE WAIVER
Per the attached as-built survey it appears the existing field is approximately 5.4’’ from
property line and therefore respectfully request a field to lot line waiver of 4’ be granted at
this time.
Granting of this waiver is justified since the existing field has been in operation since 2003
with no known issues or ill effects to the property or adjacent Lot 16 property. Also, the
existing septic field is 20’+ away from this adjacent property and it is anticipated that the
field will not impact the neighboring property.
Please contact us if you have any questions.
Sincerely,
Curtis Huffman, P.E.
