Our history
The Maryland-National Capital Park Police, Montgomery County Division, is a Division within the Maryland-National Capital Park and Planning Commission. The Commission was created in 1927 to protect open space and control development in the geographical areas of Maryland that is adjacent to the District of Columbia.
In 1954, the Commission recognized the need to provide public safety for the parks under its jurisdiction and therefore created the Park Police Division. It began with three officers who worked six days a week for an annual salary of $3,000. The officers shared one police car until it broke down and the Commission purchased two used cars to replace the initial vehicle.
Two divisions were created to serve two counties, one policing the Prince George’s County park system and the other the Montgomery County park system. Both Divisions are now the second largest police agencies in their respective counties. Today, the Montgomery County Division consists of 95 authorized sworn personnel, 25 civilian employees, and approximately 36 volunteers.
