The Arlington County Board approved a plan to redevelop a 7.65-acre superblock located along the eastern boundary of Rosslyn’s core into three new blocks with a total of up to 2.5 million SF of offices, residences, retail, a hotel and public open space. The redevelopment, a joint project of Vornado/Charles E. Smith and Gould Property Company, will occur in five phases over the next 25 years. When built out, Rosslyn Plaza will be the largest single redevelopment in Rosslyn. It will offer five new buildings; major public street improvements including two new streets; portions of a planned, vehicle-free esplanade that will front I-66, and a new public park.
