Too often when we think of urban designers and city planners, we think of people drawing up plans for a booming new metropolis. But think about that for a second. No one is designing cities from scratch; on the contrary, urban designers are some of the most important problem solvers in our society. When a city is low on public recycling bins, when its public transit is failing, when it's sprawling dozens of miles into the suburbs and people are having trouble navigating their commutes, that's when urban designers get called in. As you can see from that list of examples, these designers work in a macro and micro sense. With a job that's part-architecture and part-civic engagement, urban designers help make cities the thriving and communal locales we imagine in our dreams.
