Before an impervious (hard surface) or gravel driveway to provide vehicular entrance into or exit from private property to a public highway or private street is constructed or improved, the owner shall conform to the following standards:
A.
Beginning at the surfaced edge of the finished roadway, the driveway (hard-surfaced or gravel) shall drain away from the roadway toward the property at a minimum pitch of 3/4 inch per foot along the center line of the driveway to a point where the driveway center line intersects the plane of the center line of the water drainage ditch.
B.
Where a driveway passes over a drainage ditch, the owner shall furnish and install a culvert of proper size and material to the satisfaction of the Town Highway Superintendent and/or Town Engineer in order that the unrestricted flow of water in drainage ditches shall be assured.
C.
Where a gentle drainage exists on the outside of the shoulder from the roadway and does not violate the requirements of this article as to the grade and water drainage, the Town Highway Superintendent (on Town highways), or Planning Board (on private streets), may permit the developer or lot owner to install the finished driveway without a culvert, provided that the driveway finished surface is flush with the grade of the ditch.
