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 steeply to the NW corner, at about a 30% drop. We are submitting this with a steep slopes design showing a sufficient side profile to meet the steep slopes criteria in code. 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 log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
