DOWNTOWN BROOKLYN — The Downtown Brooklyn skyline is rising.
Earlier this week, the city’s Landmarks Preservation Commission approved a proposal that would allow a 1,066-foot tower to go up at 340 Flatbush Avenue Extension, a part of which would sit on the former Dime Savings Bank, according to a spokeswoman with the commission.
