We are submitting this design and permit application for the construction of a new well and septic system. The attached site plan identifies the location of the home and 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 slopes moderately to the northeast. Ground contours are shown on the site plan showing the grade and direction of flow. Storm water drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. Test holes on the lot indicated water at 2' on May 23. This may have been due to surface runoff and frozen sublayers as the water levels on August 17 were measured at 6' below the surface. The system has been designed for groundwater at 2' below the surface. The new septic system will be a minimum of 100' from all wells and surface water, and more than 5' from the septic tank. The alternate site is located more than 10' from the primary site. The trenches will be constructed 6' from edge to edge. Please refer to the attached test hole logs and plan and profile sheets 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 8/14/23 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 & 8/14/23 To: Page: 3 of 5 2023-08-07 19:52:06 GMT 19073086608 From: Wes Anderson 460530 Mw was on Is Boris a 10142 a X all 1 z a It son ago It a an as Miller Ivor man am Notion an an a l- Field Maintenanlale Raped AnchorageTank Annual nual Inspection 907-272-3543 Darren McCas3En A+ Hume Services Tech 4rte AV'ti2s G'9M`tt}Wbrra 14319 Harold Loop, Eagle River AK99w77 ' (918) 397''�8!r AN v.tajDd �Gx tl t0b ..
