It seems those grand plans for new parkland in Greenpoint and Williamsburg are a little bit behind schedule. Not surprising, really. Much of Bushwick Inlet is contingent upon acquisition (in a rising real estate market) or eminent domain. The MTA lot on Commercial (which is part of a land swap for both open space and affordable housing) is contingent upon locating comparable space elsewhere for the MTA (when all of the city-owned land in North Brooklyn has already been promised to others). The sludge tank site at Barge Park is contingent upon the relocation of the sludge tank (which is on hold until the city can get new barges to ply Newtown Creek).
Seems like the only thing that is not contingent based is the construction of luxury towers in Williamsburg (which will mean the completion of an esplanade sooner rather than later).
