The borough-based jail system project is officially in the public review period.

The director of the Mayor's Office of Criminal Justice on Monday presented the application to the city's Planning Commission.

As News 12 has reported, the project would create four new jail sites around the city.

The proposed jail site in Brooklyn is 275 Atlantic Ave., which is currently the Brooklyn Detention Complex, operated by the Department of Corrections. The site is just across the street from Kings County Criminal Court.

Officials discussed the possible challenges for the proposal and impacts to the area, including traffic and possible impacts on historical or cultural buildings. They spoke about the possibility of building a bridge to connect the jail and the courthouse.

Monday's presentation marked the early stages of a monthslong process. The project will first go to the city's community boards, then to the borough presidents. They can hold hearings and make recommendations on the proposal before it goes back to the city Planning Commission to be approved, modified or rejected.
