(A) Easements for public utilities may be required by the Planning and Zoning Commission, Park Board, City Engineer and essential public utilities. Where the easements are determined to be necessary, they shall be provided along the rear and side lot lines and shall be a minimum of ten feet in width with a minimum five feet of the easement on each adjacent property being divided.
(B) (1) Where a watercourse, drainage way channel or stream traverses a subdivision, there shall be provided a stormwater easement for drainage right-of-way conforming substantially with the lines of the watercourse. The width of any easement shall be adequate to provide for unobstructed flow of storm runoff based on calculations made for the 100-year return period runoff and to provide a freeboard allowance of one-half foot above the design water surface level. The terms of the easement shall prohibit excavation, the placing of fill or structures and any alterations which may adversely affect the flow of stormwater within any portion of the easement. Also, the landowner shall provide periodic maintenance to ensure proper runoff conveyance. Watercourses for which the 100-year floodplain is formally defined are also subject to the applicable floodplain regulations.
(2) If it is deemed advisable by the City Engineer, the watercourse or drainage way may be re-established to conform with the proposed street pattern, in which case suitable storm drainage or retention facilities shall be installed as directed by the City Engineer.
