A. The district boundary lines shown on the official zoning district map are usually along streets, alleys, property lines, or extensions thereof; where uncertainty exists as to the boundaries of districts as shown on the official zoning district map, the following rules shall apply:
1. Boundaries indicated as approximately following the centerlines of streets, highways or alleys shall be construed to follow such centerlines;
2. Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines;
3. Boundaries indicated as approximately following corporate boundary lines shall be construed as following corporate boundary lines;
4. Boundaries indicated as following railroad lines shall be construed to be the centerline of the right-of-way, or, if no centerline is established, the boundary shall be interpreted to be midway between the right-of-way lines of such railroad;
5. Boundaries indicated as parallel to or extensions of features indicated in subsections (A)(1) and (2) of this section shall be so construed; distances not specifically indicated on the official zoning district map shall be determined by the scale of the map; and
6. Whenever any street, alley, or other public way is vacated by official action, or whenever such area is franchised for building purposes, the zoning district adjoining each side of such street, alley, or other public way shall be automatically extended to the centerline of such vacated street, alley, or way and all areas so involved shall then and henceforth be subject to all regulations of the extended districts.
B. Where physical features on the ground are at variance with information shown on the official zoning district map, or when there arises a question as to how or whether a parcel of property is zoned and such question cannot be resolved by the application of subsections (A)(1) through (6) of this section, the property shall temporarily be considered as classified A-1, agricultural residential district in the same manner as provided for newly annexed territory; the issuance of a building permit and the determination of permanent zoning shall be in accordance with the provisions providing for amendments to the zoning regulations and official zoning district map.
