BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) October 26, 2010 Municipality of Anchorage Development Services Department On -Site Water and Wastewater Program 4700 Elmore Road Anchorage, AK 99519-6650 Subject: Lot 3A-1, Block 11, McMahon Subdivision No. 2 Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The existing absorption system on the subject lot has failed and must be upgraded. We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the three-bedroom home on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic system. The existing 1,250 Gallon Septic Tank will be replaced with a new 1,000 Gallon Septic Tank. The existing tank will be decommissioned in accordance with Municipal Code. The existing absorption trench will be left intact and tied to the new system with a flow diverter valve. Also identified on the plans are the locations of the existing well on this and adjacent lots and adjacent septic systems. No conflicts exist between the proposed septic system and the wells on this or adjacent lots. A second abandoned well is also located on this lot. It will be decommissioned in accordance with Municipal Code as part of this project. Protective radii are shown to the adjacent wells. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. A test hole was recently placed on the lot which indicated Gravel with Silt and Sand (GM/GW). The percolation test performed on the underlying material resulted in an absorption rate of 4 minutes per inch. We have designed the new trench to be within the 30' radius of the location of the test hole with an application rate of 1.2 gallons per date per square foot. We are proposing to place a 38' long trench by 5' wide with a 4' effective depth. The total depth of the system will be 8.5' with the distribution line at 4.5' below the existing surface. A minimum of 3' of fill will be placed over the new absorption trench and 4' over the new septic tank. Lot 3A-1, Block 11, McMahon No. 2 November 2, 2010 Page Two The ground surface on the lot slopes slightly to the southeast in the area of the absorption trenches. The trenches will be placed parallel to the contours of the ground as much as possible and in conformance with design criteria. A minimum of 100' will be maintained between all components of the septic system and the proposed well and from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: 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.
