The district boundary lines shown on the 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 map, the following rules shall apply:

Boundaries indicated as approximately following the centerlines of streets, highways or alleys shall be construed to follow such centerline.

Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.

Boundaries indicated as approximately following city limits shall be construed as following city limits.

Boundaries indicated as following railroad lines shall be construed to be the established 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.

Boundaries indicated as following shorelines shall be construed to follow such shorelines, and in the event of change in the shoreline shall be construed as moving with the actual shoreline.

Boundaries indicated as approximately following the centerlines of streams, rivers, canals, lakes or other bodies of water shall be construed to follow such centerlines, and in the event of change in the centerline, shall be construed as moving with the centerline. The centerline shall be interpreted as being midway between the shorelines.

Boundaries indicated as parallel to or extensions of features indicated in 6-101 through 6-106 above shall be so construed. Distances not specifically indicated on the Zoning District Map shall be determined by the scale of the map.

Whenever any street, alley or other public way is vacated by official action of the City Council or whenever such area is franchised for building purposes, the zoning district line 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 area so involved shall then and henceforth be subject to all regulations of the extended districts.

Boundaries indicated as dividing a lot or tract shall be construed as being located as shown on the Zoning District Map. Distances not specifically indicated on the Zoning District Map shall be determined by the scale of the map.

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 whether or how a parcel of property is zoned and such questions cannot be resolved by the application of subsections 6-101 through 6-109, the property shall be classified as A, Agricultural District.
