The Culpeper County Board of Supervisors has unanimously approved a resolution declaring English the county's official language.

The board also voted Tuesday to join other localities in seeking the General Assembly's help dealing with issues stemming from undocumented immigrants, including the costs of providing services.

It marked the first action taken by the county's governing board on the issue. Loudoun and Prince William counties have passed similar resolutions in the last several months.

Steve Walker, the rules committee's chairman, says counties have limited authority to make significant changes regarding illegal immigration. But he says the coalition might be able to suggest legislation to the General Assembly that would authorize specific actions once the localities determine what they need to do.
