If you listen regularly to our show, you've heard many of our guests talk about how places grow, how we get from one place to another, and how we can live more sustainably. Our guest this week takes all three of those questions and weaves them into one coherent set of policies that can help make next generation cities a reality. He is Doug Farr, author of the new book, Sustainable Urbanism.

Doug is an architect, urban designer and founding principal and president of Farr Associates in Chicago. He chaired the U.S. Green Building Council's LEED for Neighborhood Development Core Committee.

We'll talk to Doug Farr about sustainable urbanism and the 2030 Community Challenge this week on Smart City.
