Where uncertainty exists with respect to the boundaries of the various districts shown on the district map accompanying and made a part of these regulations by reference, the following rules apply:
(A) The district boundaries are roads unless otherwise shown, and where the districts are bounded approximately by roads, the road shall be construed to be the boundary of the district.
(B) Where the property has been or may hereafter be divided into blocks and platted lots, the district boundary shall be construed to coincide with the nearest platted lot lines; and where the districts are bounded approximately by platted lot lines, the platted lot lines shall be construed to be the boundary of the district, unless the boundaries are otherwise indicated on the maps by legal description.
(C) In unplatted property, the district boundary lines shall be determined by use of the scale appearing on the map, unless the boundaries are otherwise indicated on the maps by legal description.
