Jeffrey Tumlin is a principal and director of strategy at Nelson\Nygaard Consulting Associates, a North American transportation planning and engineering firm that focuses on sustainable mobility. For more than twenty years, he has led station area, downtown, citywide, and campus plans; his major development projects have succeeded in reducing their traffic and CO2 emissions by as much as 40%, and accommodated many millions of square feet of growth with no net increase in motor vehicle traffic. These projects have won awards from the Institute of Transportation Engineers, American Planning Association, Congress for the New Urbanism, and Urban Land Institute. During 2016-17, Jeff was the interim director of Oakland’s first Department of Transportation, helping the city create the new department and develop its first budget. A dynamic and frequent guest speaker, Jeff is the author of Sustainable Transportation: Tools for Creating Healthy, Vibrant and Resilient Communities (Wiley, 2012).
