I'm new here, in fact I am new to the whole planned community thing.
My interest comes from an article I read in Popular Science more than 20 years ago. It gave a brief overview of an idea for a new city in England. The city consisted of a circular highrise one mile in diameter, with no cars allowed in the center. This seems to me to be an idea whose time has come. Millions of gallons of gasoline could be saved if people could walk to work, school, shops, restraunts, etc. Such a city would have a realitively low cost to build and maintain if there were no streets, all utilities could be in tunnels under the buildings, no school buses for children and on and on.
my question is where such cities ever built? If so, or even if not, what are the pros and cons. I could imagine a very livable city with some real community aspects that don't exist in most cities since most people don't live in the same community they work in.
