When any uncertainty exists with respect to the boundaries of any of the districts listed in § 1260.02, as shown on the Zoning Districts Map, the following rules shall apply:
(a) Where a district boundary is indicated as approximately following the centerline or right-of-way line of a street, the centerline or alley line of an alley or the centerline or right-of-way line of a highway, such a line shall be construed to be such district boundary.
(b) Where a district boundary is so indicated that it is approximately parallel to the centerline or right-of-way line of a street, the centerline or right-of-way line of an alley or the centerline or right-of-way line of a highway, such district boundary shall be construed as being parallel thereto and at such a distance therefrom as is indicated on the Zoning Districts Map. If no distance is given, such dimensions shall be determined by the use of the scale shown on such Map.
(c) Where a district boundary is indicated as approximately following a lot line, such lot line shall be construed to be such boundary.
(d) (1) Where a district boundary is so indicated that it does not follow or parallel street, alley, highway or lot lines, but connects points established by the intersection of such lines, such straight lines connecting such points shall be construed to be such district boundaries.
(2) Where a district boundary is so indicated that it follows a topographical feature, such line shall be construed as following the centerline of such feature. The location of such topographical feature shall be determined by the use of the scale shown on the Zoning Districts Map.
(e) Whenever any street, alley or public way is vacated in the manner authorized by law, the zoning districts adjoining each side of the street, alley or public way shall be automatically extended to the center of such vacations, and all areas included in the vacation shall then and henceforth be subject to all the regulations of the extended districts.
