I wonder if the BizJournal has the most up to date information on the office square footage. Last I heard, and have a rendering for, the amount of office space was reduced by about 400,000sf and one of the apartment buildings was changed to 80 condo units overlooking the lake. The condo tower picked up a second building too.
I'm not going to say that the comment about the center of the region shifting is right or wrong, but it seems flawed. Even once Wildhorse Village, Chesterfield Mall Redevelopment, and Riverpointe in St. Charles are all completed, the concentration of residents and office workers will still likely remain the highest from 170 to the River. The three projects I mention, in my view, form new centers for the Western Suburbs as growth out that way doesn't seem to be slowing down. The people who live out there made the choice to live out there and while many of us see that as a flawed, costly move on their part, developers see it as an opportunity to bring "urban" style developments to those people as a means of protecting everyone's investment. And like I said earlier in this thread, just maybe worded differently, it's not like the people out in these suburbs would ever venture past 170 for anything other than a Cardinals, Blues, or City SC (future) game.
There's still a tremendous opportunity to strengthen the core, and most urban part, of the Region while allowing things like this to take place further West. The urban areas can still see more residential infill which could then support additional restaurants, shops, and so on. From there, the discussion surrounding more hotel rooms and office space can be had.
