Hmm, I really have no idea. As far as I know, it could be right away or sometime late 2013-early 2014 (which seems likeliest, to me).
I just know that downtown Austin is going to feel like one big construction zone in 2013. We're looking at maybe 15 or 16 projects here. And, wow, I just noticed that -- according to
this, at least -- GreenWater is projected to get started early 2013. Woohoo!! Not sure if that means all 4 of the buildings or just one? I guess we'll find out.
