The two-tower rental at 420 Carroll Street includes 360 apartments, 25 percent of which are priced below market rate, commercial space, and a new public promenade along the Gowanus Canal. The rezoning covers an 82-block area surrounding the canal and should create roughly 8,500 apartments in the neighborhood, including 3,000 affordable units, as well as new parkland and four acres of open waterfront space. “As the first development borne from the Gowanus Neighborhood Rezoning to launch an affordable housing lottery, this milestone at 420 Carroll represents an important stride for the development of the neighborhood,” Matt Schwartz, co-CEO of the Domain Companies, said.
