Where uncertainty exists with respect to the boundaries of any of the zoning districts as shown on the Official Zoning Map, the following rules shall apply:
(a) Parallel District Boundaries.
Where district boundaries appear to be approximately parallel to the center lines or street lines of streets, or the center lines or right-of-way lines of highways, such district boundaries shall be construed as parallel thereto and at such distance therefore as indicated on the Official Zoning Map. If no distance is given, such dimensions shall be determined by the use of the scale shown on the Official Zoning Map.
(b) Lot Lines, Railroad Lines, and Waterways.
(1) Where district boundaries approximately follow lot lines, such lot lines shall be construed as a boundary of a zoning district.
(2) Where the boundary of a district follows a railroad line, such boundary shall be deemed to be located in the middle of the main tracks of said railroad line.
(3) Where the boundary of a district follows (or parallels) a waterway, such boundary shall be deemed to be located in the middle (or parallel to) the centerline of said waterway.
(4) Any area within the corporate limits of the City which is under water and not shown as included within any district, shall be subject to all of the regulations of the district which immediately adjoins the water area. Where the water area adjoins two or more districts, the boundaries of each district shall be construed to extend to the center of the water area.
(c) Vacation of Streets and Alleys.
Whenever any street, alley or other public way is vacated by official action of Council as provided by law, the zoning district adjoining each side of the street, alley or public way shall be extended automatically to the center of such vacation. Depending on the side or sides to which such lands revert, all area included in the vacation shall then and henceforth be subject to all appropriate regulations of the extended district or districts.
(d) Interpretation by Board of Zoning Appeals.
Any questions of interpretation of the Official Zoning Map, which cannot otherwise be resolved, shall be referred to the Zoning Board of Appeals for determination, in accordance with Section 1148.03(d).
