I don't want to be too negative since it's an admirable goal, but I can't help but feel like Gall's Law applies here. I suspect it's not really possible to design a great city. Consider Brasília for instance, it was designed from the top down, and it certainly some interesting properties. Being able to walk in a mostly straight line from arbitrary point A to point B is something I enjoyed about living there. And the traffic flow control is pretty interesting and worked pretty well for a long time. However today the congestion is bad, and the design of the major landmarks is pedestrian hostile. Obviously we can improve on all the shortcomings of a city designed 60 years ago, but in designing a city today I suspect we would just create an entirely new rash of problems that were difficult to solve. Also consider that Brasília had a raison d'etre that can't be matched without political buy-in at the highest level. Again, I don't mean to entirely dismiss the idea, but I suspect that solving problems of existing cities will probably lead to better long-term results than trying to go off to a literal green field.
