Received By: Date: q /.f 1g,4 n Issued By: /�YY✓ .fliyt/�y Date: q-3.98 August 22, 1998 Municipality of Anchorage Department of Heath & Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 6, Lang Subdivision Septic System Design Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 6, Lang Subdivision intends to construct a four bedroom home on the lot. We therefore request a permit to place a new well and septic system to serve the new house. The attached site plan and backup documentation identify the size and location of the new septic system designed to serve the house. It also shows the location of the existing well and its 100' protective radius. Two testholes were placed on the lot at the locations shown. Poorly to well graded gravel was found under 4' to 5' of silty material. This material percolated at a rates between less than 1 and 5 minutes per inch. No groundwater was encountered nor was any measured during the monitoring period. We are therefore proposing to construct a 50' long X5' wide X4' effective depth absorption trench. The distribution piping w i I I be placed at 6' below the original ground surface. Total depth of the system will be 10' below the original ground surface. The surface of the lot is fairly flat in the area of the new absorption trench with a slight 1% slope from east to west and south to north. No conflicts were noted between the proposed system and those currently in place in the area. The lots to the south, west and east of this lot are vacant. Lot 6, Lang Subdivision August 22, 1998 Page Two If the system is constructed as designed 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 reserved 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.
