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 is moderately sloped with grades between 10-20% running to the south. There is one small section of existing slope that is at or under 35% where we are proposing a new septic system on the south side of the property. The current design meets all steep slope provisions as stated in 15.65.210.B.4 of the MOA Wastewater Code. An existing subdivision test hole was used for this design and we intend to confirm soils with another test hole prior to construction. Historical soils tests for this lot and the surrounding lots indicate consistent GP/GM soils with percolation rates under 1 minute per inch, and no groundwater in the month of October. Contour lines 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. The new system will be greater than 100’ from all wells and surface water. The well will be located greater than 50’ from the existing stream near the west propertyline per requirements of Title 21 Chapter 7. The alternate site is located greater than 6’ away from the primary site, and the tank will be a minimum of 5’ from proposed trenches as well as 10’ from the building foundation. Please refer to the attached plan, profile page, and test hole log for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

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 6/9/23 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 & 6/9/23 M�1�UMUPZL-'JYOFANCHOSAGE Development Services Department k p p `- Phone: 907-343-7904 On -Site Water & Wastewater Section Fax: 907-343-7997 Certificate of On -Site Systems Approval Parcel I.D. 067-231-10 Expiration Date:v� cTb�S�� 3i, �Z� 1.

The septic system is installed and was inspected during the installation. However, during the preparation of the final engineered record drawings, we discovered some minor deficiencies that need to be corrected before the septic permit can be closed out. Our final measurements showed that the monitoring tubes had been knocked around during backfill, and do not reflect the 6” effective depth of the trench. The laterals were also disturbed and are approximately 3” out of level along their length, in opposite directions. Finally, the cover over the septic tank is short by approximately 6”. When we informed the contractor, we discovered that he had left Alaska and was spending time with family in Oklahoma. The developer attempted to hire another contractor to fix the trenches, but the weather turned and the ground has since frozen. The system is currently working, and there is no threat of contamination or system failure over the winter, but it would be extremely difficult to dig up the lateral and fix the pipes with the ground frozen. We request that a conditional COSA be issued for this system until the spring, when the ground thaws and the system can be excavated and fixed. We have received three bids from contractors and placed 150% of the highest bid in escrow for this purpose.
