Subject: Spruce Terraces, Lot 10
Septic System Permit Request
This is a design narrative for a permit to install a new septic system on the subject property. The proposed system will serve a
proposed four‐bedroom (4) house. This lot and surrounding lots are served by a community water system. There are no wells
within 200’ of this system.
1. Soils:
A test hole was performed on this lot by Pannone Engineering Services, LLC on 10/13/2020. Groundwater was not observed
during the excavation of the test hole, and bedrock was not encountered. No groundwater was observed in the test hole
monitor tube after 7‐days. The test hole on lot 10 was found to have a percolation test result of 3.7 minutes per inch. 27 test
holes were performed in this subdivision by PES for the approval of the subdivision, and more were performed during the
design of septic systems on lots in the subdivision. No groundwater has been observed in the subdivision. Bedrock was not
encountered anywhere in the subdivision. The test holes in the area were all found to have a percolation of less than 5 MPI,
some less than 1 MPI. See soils logs for subdivision, S12577. The test hole on lot 10 was performed further to the north than
the system will actually be installed. We are using surrounding test holes as a justification. Based on the results of the
surrounding percolation tests and known soil types in the area, per 15.65.210 C; a conservative application rate of 1.2
gallons/day/square feet was used for a conventional wastewater system.
2. Soil Absorption System Design.
a. See Sheet 1 of the design package.
3. Surface Water:
There is no surface water within 100 feet of the proposed septic tank and drain field.
4. Topography:
See attached site plan for area topography. There are no steep slopes in the area of the drain field.
5. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is
complete and no further comments are received from MoA On‐Site Department, the note will be removed and “For
Construction” drawings will be issued.
The proposed installation will not affect the future development of this or the surrounding lots.
If you have any questions or concerns, please contact me at (907) 745‐8200.
Sincerely,
SRP

G.CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER
Phone Name of Firm
Engineer’s Printed Name
COSA Checklist_May2025.docx
Date
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.
In conducting an adequacy test, I attempt to provide a thorough, conscientious
engineering analysis of the system in accordance with ADEC & MOA guidelines and
regulations. The reported results describe the performance of the 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 septic systems depend
on the local soil condition, ground water levels that may fluctuate during the years, and
the water usage of the people served by the system. These conditions are outside the
control of the evaluator of this system. All systems eventually fail, and satisfactory test
results do not guarantee future performance if the system, nor do they guarantee that
there are no hidden defects of encroachments. Therefore, we cannot provide any
warranty of future performance, nor can we estimate the remaining life of the system.
The content of this report is for the sole benefit of the owner listed above.
