The location and boundaries of said districts are hereby established as shown on the Official Zoning Map of the Town of Lyons, which is attached hereto and is hereby made a part of this chapter.[1] Said map or maps and all notations, references, and designations shown thereon shall be, as such, a part of this chapter as if the same were all fully described and set forth herein.

Editor's Note: The Zoning Map is included as an attachment to this chapter.
A. 
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, waterways, or Town boundary lines, all as shown on the Official Zoning Map; but where a district boundary line does not follow such a line, its position is shown on the Official Zoning Map by a specific dimension expressing its distance in feet from a street line or other boundary line as indicated.
B. 
Determination of locations of boundaries. 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 Official Zoning Map, shall be determined by the use of the map scale shown thereon. Where the boundary of a district follows a stream or other body of water, said boundary line shall be deemed to be at the limit of the jurisdiction of the Town of Lyons, unless otherwise indicated. In case of uncertainty as to the true location of a district boundary line in a particular instance, the Zoning Inspector shall request the Board of Appeals to render its determination with respect thereto.
