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) Where district boundaries are indicated as approximately following the center lines of highways, or highway right of way lines, such center lines or highway right of way lines shall be construed to be such boundaries;
(b) Where district boundaries are so indicated that they approximately follow the lot lines, such center lines shall be construed to be said boundaries;
(c) Where district boundaries are so indicated that they are approximately parallel to the centerlines or right of way lines of highways or lot lines, such district boundaries shall be construed as being parallel thereto and at such distances therefrom 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;
(d) 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;
(e) Where the boundary of a district follows a stream, lake, or other body of water, said boundary line shall be deemed to be at the limit of the jurisdiction of the City unless otherwise indicated;
(f) When an actual street, lot of other boundary designation existing on the land is in conflict with that shown on the Official Zoning Map, or the Hillside Overlay Map, the Board of Zoning Appeals shall make an interpretation as provided for in Chapter 1129.
