Disputes shall be settled according to section 10.56 (c) (2) , MAPPING DISPUTES of this ordinance. (3) Where no flood profiles exist, the location of the flood plain boundary line shown on the map shall be determined by the Zoning Administrator based on visual on-site inspection and other available information.
