Pannone, Principal Registered Professional Engineer E-mail:steve@panengak.com September 7, 2018 Subject: Drake B1 L2A Tank Replace Permit Request Design Narrative This is a design narrative for a permit to install an upgrade 1,500g Septic Tank to replace an existing 1,000g Septic tank to be issued for this property. The existing tank is too small to service the existing 5 bedroom house, It will be decommissioned per code. Currently the lot is developed. The proposed 1,500g septic tank will be connected to the existing lift station. The existing tank is located outside of the 100' protective well radius. The proposed tank will be placed outside the 100' protective well radius. 1. Upgrade Tank Design. A foundation clean out installed if needed. The tank will be located: 5'+from any property line 10'+from building foundation 10'+from any water line 100'+from any surface water 100'+from any private wells 200'+from any public wells 2. Existing Drain Field. The existing septic system was installed in June of 2006 by Beeks Excavation under ADEC guidelines. It was documented by Pannone Engineering Service on 8/22/2018 and 9/3/2018.The attached drawings show the dimensions and location of the septic system. The proposed installation will not affect the future development of the surrounding or existing lots. If you have any questions or concerns, please contact me at 907.745.8200. Sinc Steven R.

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.
