Just telling you what I think will happen. I'm not saying that I disagree with the idea behind it, just that the politicians will shy away (even run from) the idea of anything other than a convention center.
Don't misunderstand, I think you guys did fine work, and no doubt the politicians will "engage" the community as it's the politically smart thing to do and costs virtually nothing to do. This is after all, public money, and it's always a touchy subject when public financing is concerned. I could even predict for you how this will play out: Lots of nice renderings and plans will be put forth to the public, and then the cost estimates will come. Then all of a sudden there will be vocal objections from citizens, and then the various commissions involved, and they'll look for areas to cut (aka value engineer), and somebody(s?) will complain that the mission is to build a convention center ONLY, and it must be cost-effective, etc.,etc., etc. I've seen it umpteen times before, and I'll bet you have too. You might get some nice architecture, but not with the Roman forum and apartments and retail, etc.. I'm quite sure that in the end you'll get a box.
Whether you agree with me or not, you know politicians probably as well as I do. When have they not acted this way?
Oh, and with all due respect, there's no way a piddling 350K convention hall (and that is what it's supposed to be, no?) can blow away a 1.5M convention center (not counting the Dome). So let's not get into a p***ing match on CC's.
