Where district boundaries are indicated as approximately following lot lines, the center line of streets or highways, highway right-of-way lines, or railroad center lines, such lot lines, center lines or highway right-of-way lines shall be constructed to be such boundaries.

Where district boundaries are so indicated that they are approximately parallel to the center line of streets or highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the Zoning Map. If no distance is given, such dimension shall be determined by the use of the scale shown on the Zoning Map.

Where the boundary line of a district follows a stream, lake or other body of water, the boundary line shall be deemed to be the limit of the jurisdiction of the Borough, unless otherwise indicated.
