The Brooklyn Heights Blog posted a tip from one of its readers yesterday suggesting that when the Purchase Building demolition is complete, the remaining plot of land may not go directly to the Brooklyn Bridge Park Development Corp., as has been expected:

I live across the street from the Purchase Building and wanted to pass on a tip regarding the space now created by the demolition of the Purchase Building. In speaking with one of the foremen from Sanska, the contractors overseeing the demolition, the DOT is making a very aggressive bid to gain control of this new space under the bridge for the next 4-5 years to store equipment and vehicles in connection with their plans to make extensive repairs to the Brooklyn Bridge. From what he can tell the DOT is winning the argument with the Conservancy and the Mayors Office. So I guess another part of the new park bites the dust.

This tip jibes with information we heard from a source knowledgeable about the situation. Click through to see a rendering of the public plaza that the Development Corp. is envisioning for the space.
