The boundaries of the districts enumerated in Section 4.01 are hereby established as shown on the Zoning Map which accompanies this Zoning Ordinance and which, with all notations, references and other information shown thereon, shall be as much a part of this Zoning Ordinance as if fully described herein. Unless shown otherwise, the boundaries of the districts are lot lines; the centerlines of streets, alleys, roads or such lines extended; and the corporate limits of the City.
Where unzoned property exists, or where, due to the scale, lack of detail or illegibility of the Zoning Map, there is any uncertainty, contradiction or conflict as to the intended location of any district boundary line shown thereon, the exact location of a district boundary line shall be determined, upon written application, or upon its own motion, by the Board of Zoning Appeals.
