Pannone, Principal Registered Professional Engineer E-mail:steve@oanengak.com November 14, 2017 Subject: DAVID RING L1 Upgrade Septic System Permit Request Design Narrative This is a design narrative to issue a permit to install an upgrade septic system to be issued for this property.The proposed system will serve an existing three(3)bedroom house that is being upgraded to a six(6)bedroom house.The system will utilize a new 2000g septic tank and an upgrade drain field. This lot and the surrounding lots are served by private wells. There are no wells within 100' of the proposed septic system. 1. Soils. PES performed in the vicinity of this system in October 2017.Ground water was not observed to a depth of 16.0' below the surface. Bedrock was not encountered in the test hole to 16.0'.There was no groundwater in the test hole monitoring tube following the seven day water monitoring period. Based on the results of the percolation tests and overall soils appearance,an application rate of 1.2 gallons/day/square was used for a conventional wastewater system 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 feet of the proposed septic tank and drain field.The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography:The existing topography on the lot generally slopes from southeast to northwest,with a slope of approximately 5%-10%in the area of the proposed drainfield. There are no steep slopes within 50'of this system. 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.

On August 15, 2002 two testholes for the proposed system were performed. The results of this test are attached. The general slope of this lot is from southeast to northwest at a grade of approximately 5-10%. We have designed our system utilizing the existing testholes that was excavated for the 3 -bedroom house, which is proposed for this lot. The lot will be served by an individual well, located on the southeastern portion of the lot. We propose to install one 2' wide deep trench. Water was not encountered during the excavation or monitoring. There are no public or private wells within 200' of our proposed system location except as noted. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 696-6111/FAX 696-8111.

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 - - -— forfature-performance;nor can-we--estimate-remaining-life-of-the-system.-The-content-ofithis-reportis-for-the-sole benefit-of-the'owne-listed• - •-• above. - Name of Firm Pannone Engineering Services LLC Phone (907) 272-8218 Address P.O.
