Where uncertainty exists with respect to the boundaries of any of the aforesaid districts, as shown on the zoning district maps, the following rules shall apply:

    A.    Where district boundaries are indicated as approximately following the center lines of streets or highways, street lines or highway right-of-way lines, these center lines, street lines or highway right-of-way lines shall be construed to be such boundaries.

    B.    Where district boundaries are so indicated that they approximately follow the lot lines, township lines, section lines, one-half section lines, one-quarter section lines and one-eighth section lines, such lines shall be construed to be the boundaries.

    C.    Where district boundaries are so indicated that they are approximately parallel to the center lines or street lines of streets, or the center lines of right-of-way lines of highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the zoning district maps. If no distance is given, such dimension shall be determined by the use of the scale shown on the zoning district maps.

    D.    Where the boundary of a district follows a railroad line, such boundary shall be deemed to be located in the middle of the main tracks of the railroad line.

    E.    Where the boundary of a district follows a stream, lake, or other body of water, the boundary line shall be deemed to be at the limit of the jurisdiction of the municipality, unless otherwise indicated. (Prior code § 40-3-2)
