This is pretty pie in the sky/ long term, but it could be a steering guideline for short term decisions.
I think developing commodore point and the warehouse district is a great idea, albeit 20 years in the future. Expanding the Hogan's creek park area is crucial for Springfield and downtown as a livable neighborhood. That garage on the back of the Crowne Plaza has always upset me, it should interact with the riverwalk more.
The main theme I get from this presentation is clustering development and focusing on creating nodes of activity throughout the core, which I think is the right way to go. Also, notice the skyway runs to the stadium and terminates in 5points at what looks like Annie Lytle. If we accomplished these things, we'd kick the tar out of our current peer cities, and our current self.
