In exceptional cases, where topography or other physical conditions would cause unnecessary hardship to the owner and not provide the Village substantial benefit, the Plan Commission may recommend to the Village Board special provisions to relieve such hardship. Any exception needed shall be requested in writing by the owner. If recommended by the Plan Commission, it shall be so endorsed by the Administrator and transmitted to the Village Board. The Village Board, if it approves, shall do so by motion or resolution and instruct the Village Administrator to notify the Plan Commission and the owner.
