SPECIAL PROVISIONS: April 21, 1997 Municipality of Anchorage Department of Heath & Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 3, Block 2, Hillside North Subdivision, Addn. No. 6 Septic System Design Impacts to Adjacent Properties Dear On Site Services Engineer: We hereby apply for a permit to construct a well and septic system on Lot 3, Block 2, Hillside North Subdivision, Addn. No. 6. The attached site plan and backup documentation identify the location, size and components of the new well and septic system proposed to serve the 3 bedroom house to be constructed on the lot. Testholes placed in the area of the proposed absorption trench revealed a silty gravel with sand with a percolation rate of 8 minutes per inch. No groundwater was noted during the monitoring period nor is any present now. The soil near the alternate site appears to percolate much faster and will require a 2' sand filter as detailed in the attached plan. The surface of the lot slopes from east to west at varying grades, 'but drops off dramatically toward the northwest corner of the prope, rty. The absorption trench will be placed to maintain a minimum of 50' separation from any 25% break in grade. The surface of the ground in the area of the absorption trench is fairly flat. The lot is of sufficient size so that no encroachments will exist between the septic system and any future wells in the area. If the system is constructed as designed the following statements can be made: 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. 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. ~;. Lot 3, Block 2, Hillside North Subdivision, Addn. No. 6 April 21, 1997 Page Two The system, if constructed as designed, will have no adverse impact on reserved 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.
