 More than 300 new homes have been approved in part of Loudoun County and Brambleton. A few dozen of them will meet the definition of affordable. County supervisors recently approved an application to rezone 80 acres of land near Ryan Road and Evergreen Mills Road. All told, 307 single-family detached homes will be built. Almost 40 of them plan to be cottage lots at 35 feet wide. They're designed to be affordable housing units. Part of Ryan Road will be widened to add some turn lanes as a result of this development.
