I missed both presentations earlier this week by Jeff Tumlin, one of the nation's leading sustainable transportation planners as a consultant at Nelson-Nygaard, and author of Sustainable Transportation Planning: Tools for Creating Vibrant, Healthy, and Resilient Communities. On Monday, he presented to the Partnership for Smart Growth in Richmond, to about 80 attendees, including a couple of City Council members and the city's bike and pedestrian planner. The Richmond.com website, affiliated with the Richmond Times-Dispatch, published a thorough summary of the talk, "10 Things Every City Can Do for Sustainable Transportation."
