O. Box 196650 Anchorage, Alaska 99519 Subject: Raptor's Knoll, Lot 2 Septic System Permit Request Ladies and Gentlemen: I am writing to request a permit to install a new septic system be issued for this property. The proposed systems will serve a proposed six (6) bedroom house. Currently the has a well installed, but is otherwise undeveloped. The proposed system will utilize a 20008 septic tank with a conventional drain field. The surrounding developed lots are served by private wells. There are no wells on surrounding lots within 100 feet of this system and there are no septic systems installed on the surrounding lots within 100 feet of the proposed well. Soils. Two test holes were performed on this lot by Michael E. Anderson in May of 2013, and groundwater was monitored for seven days. Ground water was not observed below the surface in the test hole monitor tube in May of 2013. Bedrock was not encountered in the test hole. It is my opinion, based on the results of the percolation tests and overall soils appearance; an application rate of 0.6 gallons/day/square feet should be used for a conventional wastewater system in the area of these test holes. Due to the proposed location of the house and the existing test hole's location in the central portion of the lot I request that the permit for this system be issued with the condition that a permit be issued with the condition that a test hole and ground water monitoring be performed in the location of the proposed drain field before construction is begun. The septic system is designed in the location of the septic reserve area and is based on a conservative application rate of 0.45 GPD/SF. The surrounding test holes in the area all show similar soil to the holes on this lot and the percolation rate is less than 30 minutes per inch in all nearby test holes. Additionally if adverse conditions are found in the proposed test holes the reserve drain field shown in the vicinity of TH-3 can be constructed based on CAT III. 1. Soil Absorption System Design. a. See Sheet 2 of the design package. 2. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain Mailing: P.O. Box 100217, Anchorage, AK 99510-0217 Physical: 332 East Manor, Anchorage, AK 99501 Telephone: (907) 272-8218 FAX: (907) 272-8211 Page 2 of 2 field. The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 3. Topography: The existing topography is relatively flat in the area of the proposed drain field and slopes from the east to west at approximately 20%-25% in the western portion of the lot. There are no steep slopes within 50' of the proposed drain field. The proposed drain field will maintain 50' separation all steep slopes. 4. 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 the surrounding or existing lots. There are no surrounding wells within 100 feet of the proposed septic location.

It is surrounded bY developed lots served by private wells and on site septic systems. The lots proposed for the subdivision are in excess of 40,000 square feet and are proposed to have on site wells and septic systems. Three wells are proposed for placement in the subdivision on proposed Lots 2, 5 and 6. The wells will be placed at sites which will represent standard locations relative to septic system sites and home sites on typical lots in the subdivision. Each well will be pumped in accordance with AMC 15.55.060F1 to establish the sustained yield as determined by the well driller.. Water quality testing from each well will be accomplished in accordance with AMC 15.55.060F2. A formal report including sustained yield results for each well will be submitted once all data is gathered and analyzed. A permit application is attached for placement of the well on Lot 2 in the subdivision. The location of the well and the proposed reserve area for the septic system on the lot are shown on the attached Site Plan and will not impact adjacent properties. If the well and proposed septic system is constructed in accordance with our design the following statements apply: The well, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The well, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. Lot 2, Raptors Knoll Subdivision November 11,2014 Page 2 The well, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The well, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

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, 1 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.
