Designation of district boundaries. The district boundary lines are intended generally to follow the boundary lines of streets, the center lines of railroad rights-of-way, existing lot lines, the mean water level of streams and other waterways or Town boundary lines, all as shown on the Zoning Map; but where a district boundary line does not follow such a line, its position is shown on said Zoning Map by a specific dimension expressing its distance in feet from a street line or other boundary line as indicated.

Determination of locations of boundaries. In case of uncertainty as to the true location of a district boundary line in a particular instance, the Code Enforcement Officer shall request the Board of Appeals to render its determination with respect thereto.

Unsubdivided property. In unsubdivided property or where a district boundary divides a lot, the location of any such boundary, unless the same is indicated by dimensions shown on the Zoning Map, shall be determined by the use of the map scale shown thereon.

District boundary following water body. 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 Town of Phelps unless otherwise indicated.
