One of the fastest growing cities in the U.S., Bend, Oregon has doubled in population over the past two decades. Still, it has at least some intelligent thinking about growth. Tom Hickmann, Bend Oregon's director of engineering and infrastructure planning, shares the fast-growing city's somewhat unique approach to city planning, and discusses Oregon's requirement that cities accommodate growth. According to Tom, cities get challenged if they have a "pattern and practice of rejecting growth." Tom shares the newest infrastructure planning tool, genetic algorithms, explaining how it allows cities to plan better and grow more efficiently. Planners can put the values of the environmental, development, engineering and general residential communities into this planning model to guide a community's decisions.
