Distances shown on the Zoning District Map are perpendicular or radial distances from street lines measured back to the zone boundary line, which lines in all cases, where distances are given, are parallel to the street line.

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

Where district boundaries are so indicated that they approximately follow the lot line, such lot lines shall be construed to be said boundaries.

Where district boundaries are so indicated that they are 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 being parallel thereto and at such dimension shall be determined by the use of the scale shown on said Zoning District Map.

Where the boundary of a district follows a stream, river or other body of water, said boundary line shall be deemed to be at the limit of the jurisdiction of the Village of Geneseo unless otherwise designated. If no distance is given, the dimension shall be determined by the use of the scale shown on said Zoning District Map.

If an uncertainty still exists as to a boundary line following review of the above items, then the Zoning Board of Appeals shall determine such boundary location.
