Pannone, Principal Registered Professional Engineer E-mail:steve@panengak,com June 5, 2017 Subject: T15N, R1W, Sec 8, Lot 20 Well and Septic System Permit Request Design Narrative This is a design narrative for a permit to install a well and septic system to be issued for this property. The proposed systems will serve a proposed four (4) bedroom house. Currently the lot is undeveloped. The lots to the north, west, and south are undeveloped. The surrounding developed lots to the east are served by private wells that are over 100' from the proposed development on this lot. There are no wells within 100' of the proposed septic system. 1. Soils. One test hole was performed on this lot by PES in September of 2016, and groundwater was monitored for at least seven days. Ground water was observed at a depth of 7' below the surface in the test hole-1 monitor tube in September of 2016, and at a depth of 4' below the surface in May of 2017. Bedrock was not encountered in the test hole. Based on the results of the percolation tests and overall soils appearance; an application rate of 1 gallons/day/square feet was used for a conventional wastewater system with a sand filter in the area of the test hole. 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100' of the proposed septic system. The system will maintain 100' of separation to all surface water. 4. Topography: The existing topography generally slopes from the south to the north in the area surrounding the septic system at approximately 5%. There are no steep slopes within 50' of the proposed drain field. The proposed drain field will maintain 50' separation all steep slopes. 5. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification that the review is complete and that there are no further comments is received from MoA On-Site Department, the note will be removed and "Issued for Construction" drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. Mailing: P.O.

STATEMENT OF INSPECTION B$seNG4NE As certified by my seal affixed heref9Rllldpf the validation date'sM ,wn below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approvar..Guidelines for thi '.application, shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional"and adequate for-the numbf bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchofage 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. Name of Firm Pannone Engineering Services LLC Phone (907) 272-8218 Address P.O.
