Where uncertainty exists with respect to the boundaries of any of the zoning districts as shown in the Official Zoning Atlas, the following rules shall apply:
(A) Boundaries indicated as approximately following the centerlines of streets, highways, or alleys shall be construed to following such centerlines.
(B) Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.
(C) Boundaries indicated as approximately following city limits shall be construed as following such city limits.
(D) Boundaries indicated as approximately following railroad lines shall be construed to be midway between the main tracks.
(E) Boundaries indicated as approximately following the center lines of streams, rivers, canals, lakes, or other bodies of water shall be construed to follow such centerlines.
(F) Boundaries indicated as parallel to or extensions of features indicated in divisions (A) through (D) above shall be so construed. Distances not specifically indicated on the Official Zoning Atlas shall be determined by the scale of the maps contained in the atlas.
(G) Where physical features existing on the ground are at variance with those shown in the Official Zoning Atlas, or in other circumstances not covered by divisions (A) through (E) above, the Board of Zoning Adjustment shall interpret the district boundaries.
(H) Where a district boundary divides a lot which was in single ownership at the time of passage of this chapter, the Board of Zoning Adjustment may permit, conditionally, the extension of the regulations for either portion of the lot not to exceed fifty (50) feet beyond the district line into the remaining portion of the lot.
(I) Whenever any street, alley, or other public way is vacated by official action as provided by law, the zoning district adjoining the side of the public way shall be extended automatically, depending on the side or sides to which such land reverts, to include the right-of-way of such vacated public way; thus, all regulations of the adjoining district or districts shall be extended to include such public ways or rights-of-way.
(J) In every case where property has not been specifically included in a particular zoning district, the same is hereby declared to be in the R-1 District.
(K) Territory annexed to, or consolidated with, the city subsequent to the effective date of this chapter shall be temporarily zoned per current use, as of date of annexation or consolidation. Such districting shall be temporary, and within one year, the Planning Commission shall recommend to the Board of Commissioners final zoning atlas maps for the annexed territory. In the absence of such action by the Planning Commission, the temporary zoning classification at time of annexation of consolidation shall remain as the applicable zoning of the area until amendment upon proper application and the Official Zoning Atlas shall be updated accordingly.
