The Columbia Street Waterfront District is a neighborhood in the borough of Brooklyn in New York City on the Upper New York Bay waterfront between Cobble Hill and Red Hook and situated on the western side of the Brooklyn-Queens Expressway (BQE). The neighborhood is locally governed by Brooklyn Community Board 6. The neighborhood was formed in 1957 when the newly built BQE effectively cut Columbia Street from Carroll Gardens and Cobble Hill, its two adjacent neighborhoods. The district, once an area that was blighted by empty storefronts, was further emptied of tenants by a construction disaster that caused the death of a construction worker and the demolition of 33 buildings. By 1984, an urban renewal project was completed, as well as a brand-new street, houses along which sold out quickly.
