In 1999, the city announced a revitalization initiative for the neighborhood focused around the Columbia Heights Metro station
, which opened that year. There had already been positive developments along lower 14th Street and the U Street corridor. The opening of the Metro station served as a catalyst for the return of economic development and residents.
Within five years, the neighborhood had gentrified
considerably, with a number of businesses (including a Giant Food
supermarket and Tivoli Square
, a commercial and entertainment complex). Middle-class residents settled in the neighborhood. Unlike some gentrified neighborhoods in the city, Columbia Heights has not become homogeneous: as of 2006, it is arguably Washington's most ethnically and economically diverse neighborhood.
Housing includes high-priced condominiums and townhouses, as well as public and middle-income housing.
