We are submitting this permit application for the construction of a new well and septic system to serve the home. The attached site plan identifies the location of the home and the proposed well and septic system. No conflicts exist between this proposed well and septic system and any other well or septic system on adjacent lots. The ground surface on the lot is virtually flat in the area of the new trench but slopes to the west at shallow grades. Surface contour lines are shown indicating direction of flow. Storm water flow will not impact the proposed septic system. Wells on this and adjacent lots are shown. The new septic system will be a minimum of 100’ from the well on this lot and 100’ from all wells on adjacent lots and any surface water. The tank will be 10’ from the house foundation and 5’ from deck and stair supports. Please refer to the attached plan sheet for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties. Sincerely, Michael E.
