April 15, 2003 Municipality of Anchorage Development Services Department on-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Lot 4, Wild Iris Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 4, Wild Iris Subdivision intends to construct a four-bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the home. The attached Site Plan and backup documentation identify the location of the well and configuration of the new septic system and alternate site and the parameters used in the design. Also identified on the plans are the test hole locations and the wells and septic systems on the surrounding lots. Drainage arrows and spot elevations are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. The test holes placed near the location of the proposed absorption trench indicated clean sands and gravels with varying amounts of silt with a percolation rate of 4minutes per inch. No ground water was found during placement of the test holes and none was noted dudng the monitoring pedod. We are therefore proposing to place a 1,250 gallon septic tank and a new 50' long by 5' wide by 4' effective depth absorption trench. The total depth of the trench will be 7' below the surface with the distribution pipe at 3' below the surface. Sufficient fill will be placed to prevent freezing of either the septic tank or the absorption trench. The ground surface on the lot slopes as shown on the site plan from south to north at varying slopes. The absorption trench will be constructed parallel with 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 wells 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. Lot 4, Wild Iris April 15, 2003 Page Two 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. 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. 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.
