Lol, if you're a planner for the city we've probably sat in a couple meetings together then. I've seen how well it can and does work in many cities overseas, some who have always worked that way others who are trying to be more sustainable. Planning neighborhoods to be inclusive to all needs, having housing, some jobs, groceries and even some restaurants all within walking distance with public transit linking in to allow easy access to larger services like non-emergency medical...it's like night and day. It could actually be done fairly easily but it is a completely different mind set to the general thought pattern here in the US.
