Residents rallied outside of Borough Hall on Monday and demanded that Borough President Eric Adams not vote in favor of selling the Brooklyn Heights library.
The group chanted, held signs and have sent a letter to the Attorney General's Office, asking them not to turn the library into a mixed-use high-rise.
The plan is to sell the city-owned Brooklyn Heights library site for $52 million.
The library will then be destroyed and turned into a mixed-use high-rise with a new library and condos.
The plan is in the final stages and just needs approval from the Borough Board, which Adams and City Council members sit on.
The group opposing the deal claims that there hasn't been enough transparency during the process and doesn't want the final vote to go through on Tuesday, March 1.
A spokesperson for the borough president said they have taken time to review the proposal and have postponed the vote in the past. It is now up to the Borough Board to make its determination.
