Prince William County submitted a redistricting plan to the Department of Justice that renames the Dumfries District and reflects the outcry from residents to keep certain neighborhoods whole during the redistricting process.

The map outlines the county’s seven magisterial districts for the next 10 years and evenly redistributes the 400,000-plus Prince William residents. Through the redistricting process, supervisors also changed the name of Supervisor Maureen S. Caddigan’s district to Potomac.

County officials said the Urban Land Institute recommend renaming the Dumfries District almost 10 years ago when it conducted a study on how to revitalize the Route 1 corridor. Urban Land Institute officials had said naming it Potomac would connect the community with its natural resource, the Potomac River.

The unanimously approved map does more than rename a long-standing county district. The map — one of four that county residents and officials deliberated over for the past month — keeps the West Gate, Sudley, County Center, Princedale and Ridgedale communities together. It also reunites the River Oaks community in Woodbridge after residents of the minority-majority community made a last-minute plea to supervisors.

The Department of Justice has 60 days to approve the map. Once county officials get the go-ahead, the registrar will mail voter cards to all registered voters to inform them of their voting district and location.

A copy of the county’s submission is available at Comments should be sent to the United States attorney general.
