Riverfront easement area. On each lot adjacent to the Hudson River, the owner, in connection with development or redevelopment thereof, shall make adequate provision for an easement or other form of encumbrance along, or in close proximity to, the bank of the Hudson River, to allow access for riverbank maintenance and to allow passage along the riverfront by pedestrians and bicyclists. Such easement area shall have a minimum width of 30 feet and shall be provided with a paved walkway, provided, however, that the Planning Board may approve a lesser width at locations where the thirty-foot width is not practicable. If a bicycle path is to be included, such path shall be separated from the pedestrian walkway. Such easement shall be granted in perpetuity, without charge, upon such terms as the Planning Board or other governmental authority having jurisdiction shall deem appropriate to assure the continued maintenance thereof. Such easement area shall be designed so as to be contiguous with easement areas in other properties. If, with respect to such easement for walkway or bikeway purposes, any requirements or recommendations of the State of New Jersey or any department or agency thereof would impose more stringent requirements on an applicant than those required herein, the more stringent requirements shall be deemed to be incorporated in this chapter.
