Discussions have been held with Mr. Roll Strlckland of D.E.Q. ~egard. l.ng solls information for this lot. Mr. Strlckland provlded Information on the lot across the street (Lot 14 Bk 2) which showed gravelly sand wlth a trace to some silt and cobbles. A rating of 85 was given for on-slte sewage whlch, corresponds to the general rating for the area. Our own experience based on a:test hole for Lot 19 Bk 2 indicated a rating of 125.

Also we have shown some proposed locations on the topographlc map for seepage plts and wells.

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.

Date Engineer's Comments: In conducting this evaluation, GEG, LtD. attempted to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC and MOA DSD Guidelines & Regulations. The reported results described 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 soils condition, groundwater 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 the system. Satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. GEG, LTD. can therefore not provide ...any warranty or future estimate of how long the system will continue to meet the operational requirements'of the ADEC or MOA DSD.

Box 196650 Anchorage, Alska 99519-6650 Attn: Jay Crewdson, P.E. Ref: Prospect Heights Subdivision, Block 1, Lot 14 - Septic System Adequacy Test. Mr. Crewdson: As we discussed via phone today, on 11/2/2011 we presoaked the drainfield on the subject property with 2000 gallons of water (delivered in 500 gallon loads) and it remained dry throughout the test. On 11/3/2011, an additional 500 gallons was introduced into the drainfield, and it remained dry. Based upon this data, the drainfield absorption capacity was deemed to be greater than 600 gallons per day. If you have any questions, please call me at 337-6719. Best Regards, Jeffrey A.

The 2005 septic tank upgrade permit and inspection report appear to be drawn incorrectly and do not agree with the approved 1982 installation. The 1987 septic tank upgrade inspection report shows swing-tie dimension arrows that could be mistaken for the location of the drainfield. The important point to notice on the 1987 report is the 27 feet of pipe replaced as noted in the remarks. That section of pipe is likely leading to the current drainfield which was installed in 1982. The drainfield was approved in 1982 with a total depth of 2 feet. The current COSA shows 3 feet from existing grade, which is assumed to be due to subsequent landscaping after the drainfield was originally installed.

The minimum well productivity required by this Department (AMC 15.55) for a 4-bedroom residence is 0.42 gallons per minute. Although the subject well currently exceeds this minimum requirement, all parties concerned are advised that the production capacity of the well may fluctuate. Restriction of non-critical water uses such as washing cars and watering lawns and gardens may be required. This advisory must be attached to all copies of the subject Certificate of On- Site Systems Approval.
