The Maryland-National Capital Park and Planning Commission (M-NCPPC), a bi-county, local government agency, operates in Prince George's and Montgomery Counties. M-NCPPC was established by an act of the Maryland General Assembly in 1927 to provide long-range planning, and park acquisition and development. In 1931, rules and regulations were written by M-NCPPC to govern conduct in the parks under its control. The Maryland-Capital Park Police was founded by The Maryland-National Capital Park and Planning Commission (through legislation in 1953) to patrol and police all designated parks in Prince George's and Montgomery Counties, Maryland.
