Pannone, Principal Registered Professional Engineer E-mail:steveCa)panengak.com July 31, 2018 Subject: Raptor's Knoll, Lot 1 Septic System Install Permit Request Design Narrative This is a design narrative for a permit to install a septic system to be issued for this property. The proposed systems will serve a proposed three bedroom (3) bedroom house. Currently the lot is undeveloped. The well on this lot has been drilled per the original permit, but moved downhill to accommodate the recently permitted drain field on the adjoining lot. This lot and the surrounding lots are served by private wells. Required separation distances to wells will be maintained. 1. Soils. One test hole was performed on this lot by Michael E. Anderson in February of 2013, and groundwater was monitored for at least seven days. Ground water was not observed to a depth of 18.5' below the surface in the test hole monitor tube after the 7 day monitoring period. Bedrock was not encountered in the test hole. Based on the results of the percolation tests and overall soils appearance; an application rate of 0.6 gallons/day/square feet was used for a conventional wastewater system in the area of the test hole. Due to the drain field that was permitted in the well radius of the permitted well on this lot, the proposed well was relocated and drilled west of the original proposed location, making it necessary to move the drain-field partially out of the test hole radius. Existing soils reports from the surrounding lots are attached to demonstrate the continuity of soils in the area, per 15.65.210.0 `Exception'. 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 generally slopes from the east to the west in the area surrounding the septic system at approximately 20%, flattening out to about 10% below the system. 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 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.
