A. The locations and boundaries of the approved Zoning Districts are shown upon the Official Zone District Map, attached hereto and made a part of this Code. The Official Zone District Map, together with all officially authorized notations, references, and other information shown thereon and all amendments thereto, shall be part of this Code and shall have the same force and effect as if the Official Zone District Map, together with all notations, references and other information shown thereon, were fully set forth and described herein.
B. The Director or his/her designee shall maintain the Official Zone District Map and shall be responsible for making any officially approved changes thereto.
C. Whenever any public Street or Alley is vacated by official action of the Board, the Zoning District adjoining each side of each Street or Alley shall be automatically extended to the center of such vacation and all area included in the vacation shall then be subject to all appropriate regulations of the extended Zoning Districts.
D. Where uncertainty exists with respect to the boundaries of the various Zoning Districts as shown on the Official Zone District Map, the following rules shall apply:
1. Unless otherwise shown or designated, where the Zoning District boundaries are either Streets or Alleys and where the Zoning Districts designated on the Official Zone District Map are bounded approximately by Street or Alley lines, the center line of such Street or Alleys shall be construed to be the boundary of the Zoning District.
2. Where the Zoning District boundaries are not otherwise indicated, and where the property has been or may be divided into blocks and Lots, the Zoning District boundary shall be construed to be the Lot Lines. Where the Zoning Districts designated on the Official Zone District Map are bounded approximately by Lot Lines, the said Lot Lines shall be construed to be the boundary of the Zoning Districts unless the boundaries are otherwise indicated on the Official Zone District Map.
3. In the case of unsubdivided property, the Zoning District boundary lines on the Official Zone District Map shall be determined by the use of the scale appearing on the Official Zone District Map.
E. Properties with Zoning Districts classified under the St. Louis County Zoning Code in effect at the time of annexation shall be the zoning classification assigned by St. Louis County until such time that the City rezones such annexed properties. When possible, the City shall rezone such property at the same time the property is annexed into the boundaries of the City.
F. All areas within the boundaries of the City which are underwater and not shown as included with any Zoning District shall be subject to all the regulations of the Zoning District which immediately adjoins the water area. If the water area adjoins two (2) or more Zoning Districts, the boundaries of each Zoning District shall be construed to extend into the water area and in a straight line until they meet the other Zoning Districts.
G. The City may from time to time formally amend the Official Zone District Map of the City by ordinance as may be deemed appropriate in the public interest. Such ordinance shall be adopted in accordance with the mandatory requirements for amending Zoning District boundaries and regulations as set forth in Sections 89.050 through 89.060, RSMo., and once approved, the Director, or his/her designee, shall be authorized to amend the Official Zone District Map accordingly. Any revisions made to the Official Zone District Map thereafter by the Director, or his/her designee, as authorized by this Section
410.040(G), shall include the placement on the Official Zone District Map of the date to which such has been revised.
