This property has existing utilities but a home was never built/installed. Zenith Homes is planning to install a new 66' x 13.5' single wide 3-bedroom manufactured home for the new owner. See attached plot plan for details. The site has an existing permitted 3-bedroom septic system installed in 1991. According to records,the existing system consists of a 1,200-gallon 2-compartment concrete septic tank followed by a 10' x 36' gravity drainfield bed(360 s.f.). Historical sizing of the drainfield for a 3-bedroom would be 360 s.f., so this system matches those sizing standards. The septic was recently pumped by Mike's Septic Service in Oct-2025 (see attached report) and the drainfield was located by Bamford Septic Repair in June-2026. The new house location proposed is less than 10 feet from the existing drainfield so a local setback waiver is attached. The house is to be a minimum of 2 feet from the existing drainfield. Also, a new retaining wall will need to be built behind the home to make a flat building site. We are also asking for a reduction from the retaining wall to the reserve drainfield setback from 10 feet down to 2 feet minimum if it is ever needed. We have set aside 450 s.f. of drainfield trench reserve area,enough for a 3-bedroom septic in Type 3 soil should it be needed in the future. There are no wells within 100 feet of the drainfield. There is a wetland at the back of this property which will be addressed by a biologist. The reserve meets or exceeds Table X guidelines. No soil is to be disturbed in this area and the reserve, as well as the primary drainfield areas, should not be used for vehicle traffic or parking.
