1. Location Of Districts:
   1. The location and boundaries of the zoning districts established by this Chapter are set forth in the Official Zoning Map, as periodically amended. The Official Zoning Map is incorporated into, and made an integral part of, this Chapter.
   2. It is the intent of this Chapter that the entire area of the Village, including all land and water areas, are included in the zoning districts established by this Chapter. Any land lying within the Village, but not shown on the Official Zoning Map as being included within a district, is classified as the R-1 Residential District.
2. Interpretation Of Boundary Lines:
   1. Right-Of-Way Lines: Where zoning district boundary lines coincide with streets, highways, expressways, easements, railroads, or waterways (streams, rivers, canals, lakes, or other bodies of water), the boundary line is construed to be the centerline of the right-of-way.
   2. Property Lines: Where zoning district boundary lines coincide with a recorded property line, the property line is construed to be the boundary line of the district.
   3. Scaled Lines: Where the district boundary lines do not coincide with a right-of-way line or recorded property line, the district boundary is determined by measuring such boundary line(s) by using the map scale as provided on the Official Zoning Map.
   4. Clarification Of Boundary Lines: The Zoning Board will decide any interpretations of zoning district boundary lines, where the application of items 1 through 3 of this section above leaves doubt as to the boundary between two (2) zoning districts.

(Ord. 19-10-26)

Any territory annexed into the Village is automatically, upon annexation, zoned as the R-1 Residential District, unless otherwise provided for in the annexation agreement or until the territory is rezoned.
