Coterminous municipality
A coterminous municipality, sometimes also known as a coterminous city or a coterminous town-village, is a form of local government in some U.S. states in which a municipality and one or more civil townships have partial or complete consolidation of their government functions. A term used for the formation of such a local government is "township and municipal consolidation." This form of local government is distinct from a municipality coterminous with a higher level of government, which is called a consolidated city-county or a variation of that term.
