The distinctive “Blue Goose” building in Ballston is heading for the proverbial wrecking ball after the Arlington County Board approved replacing it with an office and a residential building. The Board unanimously voted to redevelop the 1963 building, allowing the developer The Shooshan Company, in partnership with Marymount University, to build a nine-story office building and a 15-story, 267-unit residential building with 11 dedicated units of affordable housing.
