April 14, 2023 Municipalities of Anchorage On-Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 RE: SEPTIC SYSTEM UPGRADE PERMIT LEGAL: LAKE HILL ARECE LOT 1 The property owner has requested we obtain a permit to upgrade the failed septic system of the above referenced lot. We propose to install two deep trenches and 1500-gallon HDPE septic tank to serve the existing 3-bedroom residence and proposed 1-bedroom ADU. If groundwater is encountered at construction a 1500-gallon epoxy coated steel septic tank may need to be installed and/or the septic absorption field redesigned. The design is based on the recent test hole conducted on April 3, 2023 . No groundwater was observed at test hole excavation or monitoring and will be re-verified at construction. The slopes are moderate at 5-10% at the proposed upgrade location. The lot and area are served by private water. The design will not impact any of the neighboring properties and required separations are to be staked by a professional land surveyor prior to construction. Please contact us if you have any questions. Sincerely, Curtis Huffman, P.E.

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 5/6/2023 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 & 5/6/2023
