They would like to sell the home, so we are submitting this permit application for the construction of a new septic system. The attached site plan identifies the location of the home as well as the proposed septic location and alternate site. The ground surface on the lot slopes up a little bit to the house pad and back yard, and then drops off to the east and south. The area available for the septic system is very flat. 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. There is a shared well on the lot to the east that serves this house. The location of the buried water line can be traced in a general way by following the cleared path through the trees. Closer to the house it is more difficult to determine the exact path, but the supply line comes in to the home just on the south side of the existing septic cleanout. We have placed the new septic system more than 10’ away from the projected path of the water line. Additionally, we do not have any information about the existing crib, leach field, or holding tank. We have noted on the plans where there is an existing septic pipe, and that this must be decommissioned. 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.
