Mixed Use/TOD/New Urbanism/Form-Based Codes "Day"

I'm asking for your help.  I've blocked out one day near the end of the semester to focus directly on "modern urban development forms"--i.e., mixed use; transit-oriented development; new urbanism/neotraditional development; form-based codes; etc.  The casebook I use has about ten pages on this, and they're good, but I'd like to supplement it with at least one accessible, interesting article that would help introduce the concepts to students.  We have been talking about these concepts peripherally throughout the semester, but I'd like to spend one class focusing exclusively on them.  I've got lots of great books on these subjects, but I'm looking for an assignable article-length piece; it could be academic or general-interest.

So if you had to pick one article to give to someone as a starting point for learning about the trend toward mixed use and new urbanism, what would it be?  I'd love to know what you think.  Please leave a comment or email me your recommendations.  I'd love to share the recommendations with the blog readers too.  Thanks!
