The funds, part of de Blasio's 10-year capital plan announced Tuesday, will be spent on new closed-circuit television systems in the terminals and repairs to the buildings and docks, among other things, the Staten Island Advance first reported.
The mayor's office did not say how much of the money could come from the federal government, which would be uncertain under President Donald Trump's administration.
The city plans to use $11 million of the new funds to increase security around the ferry, including the new cameras in the terminal and piers, new identification readers for workers in more than 100 spots and replacing and upgrading vehicle barriers at the St. George Ferry Terminal, according to the mayor's office.
A large chunk of the funds, $45 million, will go towards building new arrestors, which are designed to control ships as they enter slips.
The plans also include $34 million to fully reconstruction of racks that guide boats into docks over four years, $7 million for other renovations to the slips, $11 million for repairs at the St. George terminal and $7 million for dock building, the mayor's office said.
