A plan to develop a swath of Manhattan’s west side waterfront with towers and apartments is set to be considered by the City Council next week.

The rezoning plan for half of the Hudson Yards project was approved Monday by a City Council committee. That part of the property serves as a storage and maintenance facility for the Long Island Rail Road.

The other half was rezoned in 2005.

The Related Companies won the deal with the Metropolitan Transportation Authority to develop 26 acres.

The project under consideration by the council ensures that 20 percent of all residential units will be affordable housing. That’s about 1,150 apartments out of more than 5,700.

Development has not yet begun.
