In February 2009, the City of New York granted a zoning change to the developer, Toll Brothers Inc. This allowed for a 480-unit, twelve-story super-block residential project, the first one permitted along the waterway. The city also set aside some land for a medium-sized development with 3,200 apartments. Twenty-five city blocks were allocated for 60 sites that were planned to produce a combined $500 million in tax revenues per year. Toll Brothers abandoned their project in 2010 after the Gowanus Canal was declared a Superfund cleanup site.
