City Councilman Ben Kallos hailed Thursday's City Council vote as a win for residents over billionaire developers.

"Today, the City Council voted to stop the march of supertall buildings from commercial districts on 57th Street into residential districts, where they would displace rent-regulated residents to build buildings for billionaires," Kallos said in a statement.

Since the East River Fifties Alliance's creation in 2015, the group has grown to include 45 Sutton Place buildings and 2,600 people from 500 buildings citywide, Kallos said.
