Supervisors last week approved an application to rezone 80 acres of land near Ryan Road and Evergreen Mills Road in Brambleton. They plan to build more than 300 family detached homes, 40 of them cottage lots. Those are designed to be affordable housing units. Part of Ryan Road will be widened to add turn lanes for this housing.
