In a letter to the state, the BPDA says it's resolved its long-standing issues with Don Chiofaro and the city is now OK with him replacing the Aquarium garage with a 600-foot tower (yes, just one), as part of a waterfront master plan that would also see new open space at what is now a Long Wharf parking lot and a new deck for the Harborwalk near the Moakley Bridge.
In exchange, the developer, who had long feuded with Tom Menino over the fate of the garage, promised $10 million to the New England Aquarium for improvements to the wharf it sits on.
In addition, Chiofaro agreed to find a way a way to provide at least 250 parking spaces to Aquarium visitors on weekdays and 500 spaces on weekends, both during the tear down of the garage and after the new tower goes up.
Chiofaro also agreed to pay the Aquarium up to $10 million for any revenue losses caused by visitors scared away from the Aquarium by a giant construction site in front - and to lend the Aquarium up to $20 million more in case of visitors going somewhere else. As part of the overall Aquarium deal, the current IMAX theater building might be torn down to provide more waterfront open space.
Chiofaro still needs to file a detailed new proposal for a tower - over they years, he had proposed a variety of configurations, none of which were ever good enough to satisfy Menino, some of which were too high for the FAA. The BPDA says Chiofaro agreed the new tower would "minimize net new shadow and avoid net new shadow on Long Wharf seaward of the Marriott."
The letter to the state - which has final say over all waterfront development - is an amendment to an earlier overall BPDA plan for the waterfront from Long Wharf to the Moakley Bridge that also calls for replacement of the parking lot behind the Chart House on Long Wharf with a new park and for connecting two ends of the Harborwalk with a new deck along and over Fort Point Channel behind the current James Hook lobster pound. Hook has agreed to pay $4 million for that work as part of its own proposal for a tower on that site.
