Interesting article on Planners Who Talk versus Planners Who Draw. He seems to think that the architects and urban designers are the real planners. He confuses urban design, development, and redevelopment with city planning - they are different. Both are important, and you can't have one without the other.
I think he forgot about the Planners Who Do - people who get things done, and are able to get government to accomplish things. That is not easy. And the people who are able to do this can come from a design or a policy or a political background.
Beyond the Priesthood The New Urbanists refer to themselves as "planners who draw." They call the others "planners who talk." The differences in product and process are stunning.
