In 1953, the county redistricted, forming the new Mason district from parts of the Falls Church, Lee and Mount Vernon districts and adding a seventh member to the board. Charles B. Runyon was elected to a special at-large seat on the Board of Supervisors in a special election held on November 4, 1953. The rather strange situation developed that there were now two supervisors from the Centreville and Lee districts, none from the Falls Church, Mount Vernon or Providence districts, and one supervisor at-large. This was remedied in the elections of 1955.
