Sec. 4. (a) The legislative body of a municipality may, by ordinance, annex any of the following:
(1) Territory that is contiguous to the municipality.
(2) Territory that is not contiguous to the municipality and is occupied by a municipally owned or operated as either of the following:
(A) An airport or landing field.
(B) A wastewater treatment facility or water treatment facility. After a municipality annexes territory under this clause, the municipality may annex additional territory to enlarge the territory for the use of the wastewater treatment facility or water treatment facility only if the county legislative body approves that use of the additional territory by ordinance.
(3) Territory that is not contiguous to the municipality but is found by the legislative body to be occupied by:
(A) a municipally owned or regulated sanitary landfill, golf course, or hospital;
(B) a police station of the municipality; or
(C) a solar electric generating facility that is or will be interconnected to an electric utility owned by the municipality.
However, if territory annexed under subdivision (2) or (3) ceases to be used for the purpose for which the territory was annexed for at least one (1) year, the territory reverts to the jurisdiction of the unit having jurisdiction before the annexation if the unit that had jurisdiction over the territory still exists. If the unit no longer exists, the territory reverts to the jurisdiction of the unit that would currently have jurisdiction over the territory if the annexation had not occurred. The clerk of the municipality shall notify the offices required to receive notice of a disannexation under section 19 of this chapter when the territory reverts to the jurisdiction of the unit having jurisdiction before the annexation. Territory that is annexed under subdivision (2) (including territory that is enlarged under subdivision (2)(B) for the use of the wastewater treatment facility or water treatment facility) or subdivision (3) may not be considered a part of the municipality for purposes of annexing additional territory.
