NEW YORK — The city is moving forward with plans to let a private developer build a mixed-income building on city-owned land in Manhattan.

Mayor Bill de Blasio confirmed the proposal on Monday's edition of "Inside City Hall".

The new structure will go up at the Fulton Houses NYCHA complex in Chelsea after two old buildings are torn down.

Thirty percent of the new units will be made affordable for public housing tenants.

The rest will be priced at market rate. 

Two new buildings will go up in the development's parking lot to house displaced residents.   

The mayor says the city will profit from letting a private developer build on NYCHA property. 

"Whenever we do development, the money that is giving off is gonna be used to fix the surrounding NYCHA buildings, in this case homes, for those residents and if there's any extra money, it'd go to the next nearest development and help fix that up," De Blasio said.

Congressman Jerry Nadler is one of several local officials who wrote a letter to NYCHA's interim chair, asking for the plan to be presented to residents.

Nadler also tweeted about the mayor's proposal saying "we will not accept a plan that is made without resident input, or that does not protect the Fulton Houses community for generations to come."

Repairs at the complex are estimated to total $168 million over five years.

Residents who spoke with NY1 say they will not go without a fight.

"I believe they're going to make those high risers and just forget about us. They don't even want to accommodate us. Here's families that have been here 50 years, I got tenants that's been in my building for 51 years. They don't want to accommodate with the moving, at least buy us out. A lot of the tenants in my building are not leaving. At least not without a fight," said one Fulton Houses tenant.

Sources also tell NY1 some local leaders, like City Council Speaker Corey Johnson, are also not on board with the plan.
