§ 3.9. Dedication of drainage easements.

3.9.1

General requirements. Where a subdivision is traversed by a watercourse, drainageway, channel, or stream, there shall be provided a stormwater easement or drainage right-of-way conforming substantially to the lines of such watercourse, and of such width and construction or both as will be adequate for the purpose. Whenever possible, it is desirable that drainage be maintained by appropriate means of adequate width for maximum potential volume or flow.

3.9.2

Where topography or other conditions are such as to make impractical the inclusion of drainage facilities within road right-of-way, perpetual unobstructed easements at least 20 feet in width for such drainage facilities shall be provided access to the road. Easements shall be indicated on the plat. Drainage easements shall be carried from the road to a natural watercourse or to other drainage facilities. Easements less than 20 feet may be approved by the building official. When a proposed drainage system will carry water across private land outside the subdivision and outside a natural drain, appropriate drainage rights must be secured and indicated on the plat. The applicant shall dedicate, either in fee simple or by drainage easement, land on both sides of existing watercourses subject to flooding or overflowing during storm periods, whether or not included in areas for dedication, shall be preserved and retained in their natural state as drainageways. Final plats for all subdivisions shall show (or include by note) a ten-foot-wide drainage easement along every property line whether the developer intends to channel water in these easements or not.
