Two test holes were excavated and found silty/sandy gravels with no water. The pere rate was 3 minutes with no water observed during the excavation or after the 7 day monitoring period. A deep trench system has been designed with an application rate of 1.2 gallon/sFday. The slope is semi -flat at the site but has a 35 percent slope running from the east to west over 50 feet from the test hole, see site plan.

Name of Firm: Garness Engineering Group, Ltd (GEG) Phone: 907-337-6179 Address: 3701 East Tudor Road, Suite 101- Anchorage, Alaska 99507 Engineer's Printed Name: Jeffrey A. Garness Date: `Z lllk46 In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including but not limited to, soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation. Reliance upon the information provided in this report by any other person or party (including subsequent property purchasers) is not authorized, nor will it confer any legal right whatsoever. 6.
