The de Blasio Administration has unveiled new details for one of the most significant pieces of its ambitious affordable housing plan: the rezoning of Brooklyn’s East New York neighborhood.

As New York YIMBY reported, the administration announced that it would “upzone” a stretch of Atlantic Avenue to create what it calls a “growth corridor” that could accommodate residential development up to 12 stories. Moderate density development for surrounding blocks is proposed to support “affordable and mixed-income housing, retail, businesses, and community facilities near transit.” On smaller-scale side streets, the administration hopes to preserve the neighborhood’s existing character by continuing to allow “low scale duplexes, single-family homes and rowhouses.”
