§ 160.021 ZONING DISTRICT MAP DESCRIPTION; INTERPRETATION.
   (A)   The boundaries of the zoning districts set out herein and delineated upon the Official Zoning Map of the city, said map being a part of this chapter as fully as if the same were set forth herein in detail, shall be governed by the following regulations.
      (1)   If, in accordance with the provisions of this chapter, changes are made in district boundaries or other matters portrayed on the Official Zoning Map, such changes shall be ratified by the City Commission.
      (2)   Regardless of the existence of copies of the Official Zoning Map which from time to time may be made or published, the Official Zoning Map, which shall be located in the office of the City Secretary, shall be the final authority as to the current zoning status of land and water areas, buildings and other structures within the city.
      (3)   One updated copy of the Official Zoning Map shall be filed with the Building Official and shall be used for observation in issuing building permits, certificates of occupancy and for enforcing this chapter. One updated copy of the Official Zoning Map may also be filed with the Director of Transportation and Planning for reference purposes.
      (4)   Reproduction for informational purposes may, from time to time, be made of the Official Zoning Map.
   (B)   Where uncertainty exists with respect to the boundaries of the various districts as shown on the Official Zoning Map, the following rules apply.
      (1)   The district boundaries are streets, alleys and property lines unless otherwise shown, and where the districts designated on the Official Zoning Map are bounded approximately by streets, alleys or property lines; the streets, alleys or property lines shall be construed to be the boundary of the district. Where alleys are vacated, the boundary shall be the centerline of such vacated alley.
      (2)   Where the district boundaries are otherwise indicated, and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be property lines.
      (3)   In unsubdivided property, the district boundary lines shall be determined by the use of the scale of the Official Zoning Map.
      (4)   Where the description of the property is contained in an ordinance, the metes and bounds description of the property in the ordinance shall control over the zoning map.
      (5)   When on account of any legal vacation proceeding or for any other cause the streets or alleys on the ground differ from the streets or alleys shown on the District Map, the Director of Transportation and Planning may apply the district designations on the map to the streets or alleys on the ground in such manner as to conform to the intent and purpose of this chapter.
      (6)   Questions of interpretation of the Official Zoning Map shall be referred to a person designated by the city.
