The attached site plan identifies the location of the home as well as the proposed septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. The ground surface on the lot slopes upward toward the back of the lot, and the septic system is place near the front of the lot. (There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site.) Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. The new system will be a minimum of 100’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate site is located more than 6’ away. Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the existing wells and septic systems on surrounding lots. No conflicts exist between the proposed septic system and wells 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. Five test holes were placed on the lot in the area of the absorption trenches and alternate site. All indicated a poorly graded gravel with silt (SP/SM) material with some sand. The percolation rate of the soil was determined to be between 6 and 15 minutes per inch. No groundwater was found during the placement of the test holes, but was noted at 7' below the surface during the monitoring period, which included May 15, 2005. An application rate of .8 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 2,000 -gallon septic tank and 4 - 50' long by 5' wide by 1' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 1' below the surface and the total depth will be 2'. 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. A total of 3 flow splitter valves will be placed to insure even effluent flow to each absorption trench. The ground surface on the lot in the area of the septic system slopes to the west. The Lot 27, Block 7, Kasilof Hills Subdivision November 8, 2006 Page Two new trenches will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and 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: 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.
