Mayor Bill de Blasio’s administration has championed the expansion of affordable housing throughout all five boroughs, but he, as well as the City Planning Commission, opposed the ERFA’s original rezoning proposal, which was backed by several community representatives, including Manhattan Borough President Gale Brewer and Councilman Ben Kallos, who represents the residents of Sutton Place. New York State Senator Liz Krueger has backed the proposal, and recently, New York Congresswoman Carolyn Maloney signed on in support of the ERFA’s mission, having already written and voiced concerns to the CPC on the organization’s behalf, according to an ERFA spokeswoman.
