1104.03 ZONING DISTRICT MAP AND DISTRICT BOUNDARIES.
   (a)   Zoning District Map.
      (1)   All land within the City of Mount Vernon shall be placed into at least one of the base zoning districts established in Table 1104-1. Such zoning shall be shown on the Official Zoning Map of Mount Vernon, Ohio, hereafter referred to as the "zoning map." The zoning map, including any notations, shall be incorporated and made a part of this code.
      (2)   Any changes in zoning districts made by City Council or changes to the zoning classifications of areas annexed to the City shall also be noted on the zoning map by the ZEO.
   (b)   Interpretation of Zoning District Boundaries.
      (1)   Where uncertainty exists with respect to the boundaries of the various districts as shown on the zoning map, the following rules apply:
         A.   Where zoning district boundary lines are indicated as approximately following a lot line, such lot line shall be the zoning district boundary.
         B.   Where zoning district boundary lines are indicated as approximately following a center line of a street or highway, alley, railroad easement, or other right-of-way, or a river, creek, or other watercourse, such centerline shall be the zoning district boundary. In the event of a natural change in the location of such streams, rivers, or other water courses, the zoning district boundary shall be construed as moving with the channel centerline.
         C.   Where zoning district boundary lines are indicated as approximately following City limits, such City limits shall be the zoning district boundary.
      (2)   When the actual street, right-of-way, property line boundary, or other existing ground condition is in conflict with that shown on the zoning map, the ZEO shall provide the necessary interpretation, with their decision appealable to the BZA. The person contesting the location of the district boundary shall be given a reasonable opportunity to submit technical evidence to illustrate the boundary.
   (c)   Zoning of Vacated Properties. Whenever any street, alley, or other public right-of-way is vacated in a manner authorized by law, the zoning district adjoining each side of such street, alley, or public right-of-way shall be automatically extended to the center of such vacation and all areas included in the vacation shall then and henceforth be subject to all regulations of the extended district.
   (d)   Zoning of Annexed Territories.
      (1)   Territory annexed in the City of Mount Vernon after the effective date of this code shall continue to be governed by the zoning regulations which governed the territory annexed immediately prior to the annexation, as enacted by a Board of County Commissioners under Ohio Revised Code 303.01 to 303.25, or enacted by a Board of Township Trustees under Ohio Revised Code 519.02 to 519.25, as may be applicable.
      (2)   As soon as practicable after the annexation of territory to the City of Mount Vernon, proceedings shall be instituted by the MPC to include the annexed territory in one or more of the zoning districts defined in this code, as amended. All land annexed to the City which, prior to annexation, is not subject to county or township zoning shall remain unzoned until the zoning map is amended according to the provisions of Section 1103.03.
