BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 FAX August 1, 2012 Municipality of Anchorage Development Services Department On -Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Lot 2, Halls Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 2, Halls Subdivision intends to upgrade the septic system on the lot. We are therefore requesting a permit be issued for the construction of a septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the Class C Well currently serving the home. The sewage from the house is now disposed through the septic system on the adjacent lot. No conflicts exist between the proposed septic system and well or septic systems on adjacent lots. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. A test hole was placed on the lot in the area of the absorption trench. The log indicates silty sand (SW/SM) in the zone specified for the absorption trench. The percolation rate of the soil was determined to be 3.2 minutes per inch. No groundwater was found during the placement of the test hole and none was noted during the monitoring period. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,000 -gallon septic tank and a 40' long by 5' wide by 4' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 9' below the surface and the total depth will be 13'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. The ground surface on the lot in the area of the septic system slopes to the north at a shallow grade. The slope becomes steeper with distance from the north property line. The new trench will be constructed parallel with the contours of the slope as much as Lot 2, Halls Subdivision August 1, 2012 Page Two possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 150' from the Class C Well and 100' from any surface water and 10' the proposed and existing water services 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.
