Box 196650 Anchorage, AK 99519-6650 Subject: Upgrade Sewer Permit — Audubon Hills Bl, L2 It has been determined that Advantex system was never turned on when occupancy started 2 years ago and the absorption field of the subject property is saturated. Subsequently, the owner has requested we proceed forward to obtain a septic permit to upgrade the septic system. The general slope of this lot is from east to west at a grade of approximately 4-870 over the septic area. The original testhole used for the primary field will also be used for this upgrade. The proposed upgrade will serve the existing 4 -bedroom house. We propose to install one 5 -Wide 30' long drain field. The property and adjacent lots are served by private water. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 868- 3791 / FAX 868-3793.

We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the home. The soils on the lot are inconsistent and composed of dense silt and sand with some gravel. In addition groundwater is found close to the surface in most areas which makes it difficult to place a conventional septic system. We have therefore decided to place an Advantex Treatment System on the lot to provide the most effective treatment of the septic effluent prior to discharge into the surrounding soil strata. The location of the absorption system is shown on the attached Site Plan. Drainage patterns are also shown on the plan and will not be modified as a result of the proposed construction. The test holes placed on this lot revealed silty sand with gravel. The percolation rate in the materials encountered was between 31 and 60 minutes per inch. Groundwater was found during excavation at 13' below the surface and remained at that level during the monitoring period. We are therefore proposing to place a four-bedroom Advantex Treatment System. The absorption trench will be 40' long x 5' wide with a 4' effective depth. The distribution line in the trench will be placed at 1.0' below the existing ground level. The surface slope of the lot should allow gravity flow to the absorption trench. A minimum of 2' of fill and 2" of insulation will be placed above the trench and 4' over the septic tank to meet Municipal Code and prevent freezing. The ground surface of the lot slopes from the northeast to the southwest in the area of the absorption trench. It then flows to the northwest. The trench will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 100' from any surface water and 100' from the existing well on this lot. Lot 2, Block 1, Audubon Hills October 27, 2011 Page Two No conflicts exist between the existing well and septic system and those in, the area. If the system is constructed in accordance with our design the following statements apply: 1. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, 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.
