' Benja In Schiller CE 12592 VieF�' �l1/3/21 , . �Co'Ase �F�PRQFESS14t�t`� We originally submitted an application for a tank replacement, but found the existing trench to be surcharged. We are now proposing the replacement of the whole septic system. The attached site plan identifies the location of the home as well as the well and septic location. No conflicts exist between this proposed system and any other wells or septic system, whether on this lot or adjacent lots. The ground surface on the lot slopes toward the north under 10%. There are no slopes greater than 25% within 50 feet downslope of the proposed 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. A new test hole will be done prior to construction to confirm absorption and that the minimum separation to groundwater and impermeable surfaces are met for the proposed design depth. The new septic system will be a minimum of 100' from all wells and surface water, more than 16' away from the existing trench, and more than 5' away fiom the septic tank. Please refer to the attached plan for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

We are therefore applying for a permit to construct a well and septic system to serve the house. The Site Plan shows the location of the new system along with the alternate system, well location and the location of wells in the area. The lot is currently served by a community water system which is not in compliance with ADEC regulations making the lot ineligible for construction financing. The plat for the subdivision has been researched and contains no requirement prohibiting private wells. We are hereby requesting a permit to construct a well and septic system on the lot. Testholes placed revealed silty gravel with a percoation rate ranging from 23 to 32 minutes per inch. No groundwater was encountered nor was any noted during the monitoring period. We have therefore designed a deep absorption trench system with an 8' effective depth and 63' in length. The distribution pipe will be placed at 3.5' below the surface and the total depth of the system will be 11.5' The ground surface on the lot slopes from the south to the north. At the back of the lot the slope is approximately 15% in the area of the new absorption trench. The slope flattens out to 5% near the front of the lot. The trench will be constructed parallel to the slope in accordance with Municipal requirements. Since the subdivision is served primarily by the community water system no conflicts will exist between the septic system and other wells in the area. Similarly, the well to be constructed on the lot will not conflict with private septic systems on adjacent lots. 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. Lot 9, Sheets Subdivision July 18, 1999 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. ']'he current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.
