Waiver of requirements. The Joint Planning Board may
waive, when reasonable, any requirements of improvements for the approval,
approval with modifications or disapproval of subdivisions submitted for its
approval. Any such waiver, which shall be subject to appropriate conditions,
may be exercised in the event any such requirements or improvements are found
not to be requisite in the interest of the public health, safety and general
welfare or inappropriate because of inadequacy or lack of connecting facilities
adjacent or in proximity to the subdivision.
