A proposal to redevelop the South Street Seaport includes a marina and a 50-story tower.
The company controls the seaport under a lease with New York City.
It says the proposal will include a yet-to-be-determined rescue plan for the financially strapped Seaport Museum and the sailing ships at Pier 17.
The proposal must be approved by the Landmarks Preservation Commission and the City Council.
The preliminary proposal is to be presented Tuesday to local residents and Community Board 1, which includes the seaport.
It includes demolishing the dilapidated New Market Building on the north side of Pier 17 to make room for the hotel and apartment tower.
