Municipal Boundaries

Download In State Plane Projection Here. Municipal boundaries are based on annexations, court orders and other legal documents filed in the office of the Recorder of Deeds. Mapping is based on the legal descriptions from those documents, which relate to existing parcel boundaries or to the underlying PLSS. Important attributes include "Type" which contains an "I" if the polygon represents an incorporated area, and a "U" if unincorporated. The municipality name for "I" type polygons is included in the attribute "NAME1."
