Is there another organization that supports council-manager government?
Yes, the National Civic League is a nonpartisan citizens organization founded in 1895. Its purpose is to serve as a clearinghouse for information on methods of improving state and local government; to encourage citizen participation in state and local government; and to provide guides, model charters, an laws on specific subject. The League’s Model City Charter, now in its seventh edition, has endorsed council-manager government since 1915.
