Manassas and Manassas Park are independent cities that lie within Prince William County boundaries. Each operates independently with its own city council and mayor. There are eight members of the Prince William County Board of Supervisors . The chairman is elected at-large and represents the entire County. The other seven Supervisors are elected to represent one of the seven election districts.
Supervisors serve four-year terms.
The Supervisors adopt local law, establish the policies that direct the County, hold land use hearings, provide for an orderly development of land assets and social programs. Also, by setting priorities for the use of financial assets, the Board determines which public services the County government will provide. The Board adopts the County's four-year Strategic Plan, which is the government's guiding document. The meetings are held in the McCoart Administration Building on the Prince William Parkway. Citizens are welcome to attend the Board meetings.
