(A) Easements shall be provided for all overhead or underground utility services or surface water drainage where necessary. They shall be ten feet wide and shall be established at the rear of each lot and along such other lot lines as necessary to provide continuity of alignment from block to block. At deflection points in these easements, if overhead utility lines are contemplated, additional easements shall be established for pole line anchors.
(B) In a subdivision containing 60 acres or more, where lots are to be served by individual water supply and sewage disposal systems, and future resubdivisions may be contemplated upon the installation of public or community water and sanitary sewer facilities, easements of required width shall be shown for utility and street installation at locations necessary to serve lots in any future resubdivision.
(C) Where a subdivision is traversed by a watercourse, drainageway, channel or stream, there shall be provided a drainage easement conforming substantially with the lines of such watercourse. It shall include an additional area at least 15 feet wide, adjoining both edges of the established area that has been affected by damaging flood waters, as certified by the subdivider, or his or her engineer.
(D) All existing drainage and underground utility installations which traverse property to be subdivided shall be protected by easements.
