The attached site plan identifies the location of the home as well as the proposed well, 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 gradually towards the east property line under 25% and it is in the southeast corner of the property that the new septic system will be located. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contour lines 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. There are no adjacent well radii that conflict with this property. We are proposing a shared well between lots 1 and 2, with the proposed well to be drill near the northeast corner of lot 2. The new system will be greater than 100’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate site is located more than 8’ away from the primary. Please refer to the attached test hole logs, soils lab analysis, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
