BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 FAX August 23, 2016 Municipality of Anchorage Development Services Department On -Site Water and Wastewater Program 4700 Elmore Road Anchorage, AK 99519-6650 Subject: Sue Tawn No. 2, Block 3, Lot 5 Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The absorption system on the subject lot has failed must be upgraded to prevent damage to the property. We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the one -bedroom home on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic systems. The existing septic tank will be replaced with a new 1,000 gallon steel septic tank. The existing tank and absorption trench will be decommissioned in accordance with Municipal Code. Also identified on the plans are the locations of the existing well on this lot and adjacent lots. No conflicts exist between the proposed septic system and the wells on adjacent lots. Drainage arrows are shown indicating the current drainage patterns. The ground surface in the area of the proposed trench is virtually flat. The drainage patterns will be maintained after construction. The test hole placed on the lot indicated Silty Sand with Gravel (SM) in the absorption zone of the trench. The percolation rate was determined to be between 2 minutes per inch. No groundwater was encountered during the placement of the test hole and none has developed to date. We have designed the new trench with an application rate of 1.2 gallons per day per square foot. We are proposing to replace the existing 1,000 gallon septic tank and construct a new 25' long trench by 5' wide by 4' effective depth absorption trench. The total depth of the trench will be 7' with the distribution line at 3' below the existing surface. The ground surface on the lot in the area of the new trench is flat. The trench will be placed parallel to the contours of the ground as much as possible and in conformance Sue Tawn Estates No. 2, Block 3, Lot 5 August 23, 2016 Page Two with design criteria. 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, p Michael E. Anderson, P.E.
