here is a crop of what was there, i put some labels in it. not everything labeled is gone.
basically, according to what i can gather, everything to the left of the middle is pretty much either GONE, heavily damaged, or cosmetically damaged.
if you notice to the immediate right of the towers, that area is actually an underground mall, and shopping area. the "hotel" label is covering part of it.
the street immediately to the left of the "city hall" label is broadway. I put the woolworth building there because it's a famous building.
the buildings all the way to the left with the torquoise-ish roofs are other buildings in the WTC complex.
the highway between those torquoise-ish roofs buildings and the twin towers is the "west side highway." the area to the left of the west side highway is called "battery park city." note that battery park city is a RESIDENTIAL area. you'll notice some empty areas north of the cropped picture i posted in the larger version. those areas ARE empty lots. buildings have NOT been built there yet. if you look at the big picture (manhattan_before_psh.jpg) you'll notice that battery park city basically ends. battery park city is landfill. it was created from the excavation of the WTC, twin towers, et al.
this is a crop of battery park city i went to stuyvesant.
