1311.03  INTERPRETATION OF ZONING DISTRICT BOUNDARIES.
   (a)   Where uncertainty exists with respect to the boundaries of any of the aforesaid districts as shown on the Zoning Map, the following rules shall apply:
      (1)   Where boundaries approximately follow streets, alleys or highways. Where district boundaries are indicated as approximately following the center line or street line of streets, the center line or alley line of alleys, or the center line or right-of-way line of highways such lines shall be construed to be such district boundaries.
      (2)   Where boundaries parallel street lines, alley lines or highway right-of-way lines. Where district boundaries are so indicated that they are approximately parallel to the center lines or street lines of streets, the center lines or alley lines of alleys, or the center lines or right-of-way lines of alleys, or the center lines or right-of-way lines of highways, such district boundaries shall be construed as being parallel thereto and at such district there from as indicated on the Zoning Map. If no distance is given, such dimension shall be determined by the use of the scale shown on the Zoning Map.
      (3)   Where boundaries approximately follow lot lines. Where district boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be the boundaries.
      (4)   Where boundaries follow railroad lines. Where a boundary of a district follows railroad lines, such boundary shall be deemed to be located midway between the main tracks of such railroad lines.
      (5)   Where a boundary follows a river or stream. Where a boundary of a district follows a river or stream the boundary line shall be construed to be at the limit of the jurisdiction of the City unless otherwise indicated on the Zoning Map.
      (6)   Lots in two districts. Where a district boundary line divides a lot which was in single ownership and of record at the time of enactment of this Ordinance, the use thereon and the other district requirements applying to the least restricted portion of such lot shall be construed as extending to the entire lot provided the least restrictive use does not extend more than twenty-five feet (beyond the dividing boundary line) or to the rear lot line, whichever is less. The use so extended shall be deemed to be conforming.
      (7)   Vacation of public ways. Whenever any street, alley or public way is vacated, the zoning boundary line 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 regulation of the extended districts.
      (8)   District regulations apply to schools, parks, etc. Any area shown on the Zoning Map as park, playground, school, cemetery, waterways, street right- of-way, or any other public or semipublic uses, shall be subject to the zoning regulations of the most restricted adjoining district.
      (9)   Where territory has been added by annexation. When property is annexed into the City, appropriate districts will be determined by the Planning Commission at the time of annexation based on a land use study prepared by a designated representative of the City.
