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 thoroughfares or highways, street right of way lines, or highway right-of-way lines, such center lines, street, 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 lot lines shall be construed to be said boundaries;
(c) Where district boundaries are so indicated that they are approximately parallel to the center lines or street lines of streets, or the center lines of right-of-way lines or highways, such district boundaries shall be construed as being parallel thereto and at such distance 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 Municipality unless otherwise indicated.
