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 01/20/2026 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 & 01/20/26 EPUIMIS MUNICIPALITY OF ANCHORAGE Development Services Department \ Phone: 907-343-7904 On-Site Water & Wastewater Section Fax: 907-343-7997 Certificate of On-Site Systems Approval Parcel I.D. 020-281-83 Expiration Date: z0 -1 cf 1.

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 for this application, shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is (are) in compliance with all applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation. In conducting an adequacy test, I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA 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 year,and the water usage of the family being 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 of the system, nor do they guarantee that there are no hidden defects or encroachments. Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system.The content of this report is for the sole benefit of the owner listed above.
