In the United States, a regional park is sometimes referred to as a 'Metropolitan Park (Metropark)' or as an open space reserve. The terms "region" and "metropolitan" can have different meanings in U.S. local government agencies. Regional parks can be administered by a regional park board, a state, county or other units of local government. A special authority can be set up, under the joint jurisdiction of two or more government bodies or as an independent park district to administer parks. Individual parks may or may not cross governmental boundaries. The park district holds the authority, similar to fire protection districts, to manage and raise taxes to cover park acquisition and management costs.
