In October, city officials unveiled plans to rezone a large swath of East Harlem. The major thrust of the rezoning initiative is to bring more high-rise buildings to a corridor running several blocks along Park, Second, and Third avenues. By building up, city officials hope the neighborhood will increase its housing stock, including its affordable housing stock. In the long term, the proposed rezoning will also radically reshape the East Harlem’s appearance and street life, turning it from a mostly low-rise to high-rise neighborhood. What is about to happen to East Harlem, however, is a familiar story. Since 1916, when New York passed its first zoning resolution, the city has been profoundly shaped by zoning regulations.
