This is now under construction. It is the site on the left of the map in the red outline(residential 586 units). The other red section on the right with the 365 wholefoods is also under construction. There are construction sites about this size or slightly smaller all along river road and pt imperial boulevard all the way up the hudson. This is one of the larger developments though, and seems to be about double the height of most others. All last year they had been doing piledriving but they are now out of the ground in some sections with rebar.
Here is the site as of 2 days ago.
