If no sewers or water mains are located on or immediately adjacent to the land division, the nearest such sewers or water mains which might be extended to serve the land division shall be indicated by their direction and distance from the nearest exterior boundary of the certified survey map, and by their size, and invert elevations. All elevations shall be referenced to a vertical datum approved by the town or County engineer.

The County zoning committee or town board may also require the submission of a sketch plan, drawn to scale, showing the entire contiguous holdings owned or controlled by the subdivider and identifying proposed future development of the parcel, including general street and lot or parcel locations.
