The City of Phoenix has put together a pretty informative website related to CityScape, which can be found here:
http://phoenix.gov/downtown/patriots.html
It shows a timeline related to the redesign of the Patriot's Square Park. That's the good news. The bad news? Looks like until Feb. 22, 2007 until they will have a plan finalized, which means that new designs for the project will probably take a few months more after that...and groundbreaking? Who knows...probably summer 2007 at the earliest?
