"This is to certify that this is the Official Zoning Map of Caln Township, as adopted by the Caln Township Board of Commissioners on April 24, 2008, as part of the Township Zoning Ordinance of 2005."

All changes shall be noted by date with a brief description of the nature of the change.

Where district boundaries are indicated as approximately coinciding with the center lines of streets, highways, lanes, alleys, railroad tracks, rivers or creeks, such center line shall be construed to be such boundaries.

Where district boundaries are indicated as approximately coinciding with lot lines or deed lines, which were in effect at the date of this chapter, such lines shall be construed to be such boundaries.
