Zoning district boundaries.
The district boundary lines shown on the zoning district map are generally along streets, alleys, property lines or extensions thereof. Where uncertainty exists as to the boundaries of districts as shown on the official zoning map, the following rules shall apply:
(1) Boundaries indicated as approximately following platted lot lines shall be construed as following platted lot lines;
(2) Boundaries indicated as approximately following city limits lines shall be construed as following city limits lines;
(3) Boundaries indicated as following street, highway or alley lines shall be construed as following such lines;
(4) Boundaries indicated as approximately following the centerlines of streams or drainageways shall be construed as following such centerlines;
(5) Boundaries indicated as parallel to or extensions of features indicated in subsections (1) through (4) above, shall be so constructed. Distances not specifically indicated on the official zoning map shall be determined by the scale appearing on the map;
(6) Where physical or cultural features existing on the ground are at variance with those shown on the official zoning map, or in other circumstances not covered by subsections (1) through (5) above, the board of adjustment shall interpret the location of the zoning district boundary in question.
