What, exactly, is going on the 3 1/2 acre parking lot at 85 Jay Street in Dumbo? It’s hard to say, but work crews were spotted there doing something and it’s of interest because it’s one of the most desirable parcels of undeveloped real estate in all of Brooklyn. The land is owned by Watchtower, which has been selling a lot of property over the last 18 months.–Dumbo NYC
