The Columbia Heights neighborhood in Washington D.C. experienced revitalization following the opening
of the Columbia Heights Metro station in 1999. Within a few years, new businesses like a supermarket and
entertainment complex moved in, and middle-class residents began settling in the area. While gentrification
occurred, the neighborhood maintained its diversity. The success of Columbia Heights demonstrated that urban
transit-oriented development can help revitalize existing neighborhoods by attracting new residents and businesses.
