In the event the police jurisdiction of any municipality to which this article applies overlaps with the police jurisdiction of another municipality in the county that has zoning authority in its police jurisdiction, the governing body of each municipality may exercise the zoning authority in the overlapping portions of its police jurisdiction to a boundary which is equidistant from the respective corporate limits of each municipality that has an overlapping police jurisdiction. Nothing in this section prevents neighboring municipalities from entering into cooperative agreements as to which municipality will exercise zoning authority in the areas of overlapping police jurisdiction.
