The zone symbols in this title and the boundaries of the zone districts described in this title are shown upon a map attached to the ordinance from which these provisions derive, and made a part of this title, which map is the zoning map of the city. The map and all of the notations, references, and other information shown thereon are as much a part of this title as if the matters and information set forth by such map were fully described in this title. A copy of the map and amendments thereto shall be available for public inspection at the office of the director of community development and planning. (Ord. 1987-1 § 2 (part); prior code § 5-2-6)
