I’m in love with Jeff Speck’s new book, Walkable City: How Downtown Can Save America, One Step At A Time, and I’m not even finished with it. Speck takes a fascinating look at the reasons pedestrian-friendly environments are the most desirable, healthy, prosperous urban spaces in America. The book focuses on the various problematic elements that prohibit most cities from increasing their walkability, from excess parking to single-use development. Speck’s research is extremely well documented, but the book has an informal tone that makes pages speed by. Now, if we can only act on his advice.
