Just some piddling musings on my part...
While looking at the presentation material available at
the Wolf Point website, I stumbled upon this image-
This might help explain why the developers can't push the South tower any further back. In addition to the sight corridor guarantees for the Apparel Center, it looks as if there is also a minimum setback from the main entrance of the Apparel Center, as well.
As "jarta" explained, the West and South towers need to be oriented north-south. The East tower appears to be just outside the easement zone, and that, along with the unorthodox shape of that section of the Point, lends to its odd shape.
Combine the need for a cul-du-sac (since neither the East nor South tower can orient its main entrance along Wolf Point Plaza Drive), plus two separate entry/exit points for underground parking (one for the West residential tower and one for the South & East towers), as well as the sight corridor and setback restrictions, and the building placements seem to make a little more sense.
Also, just wondering, has anyone with the know-how had the opportunity to look at the traffic study posted at the Wolf Point website? Do the figures they advance seem realistic to you? I wouldn't have a clue myself.
