Slate's Matthew Yglesias trumpets Ann Arbor's new "mixed-use" party, a group that advocates a more democratized version of urban planning that defies the politically-influenced micro-managing of urban design ordinances. Excerpt: "Of course I'm a radical who's no fan of maximum height rules anywhere, but these kind of codes are a big improvement on the idea that town planners need to micromanage where people can and can't put an office or a store.
