In theory, you can build a fine urban park atop an underground parking garage. Stroll through the gardens of Chicago’s Millennium Park, and you forget you’re walking above a cavern for 2,200 cars. But too often, such parks are treated as an afterthought and end up as a fancy roof for a garage. Once car access takes precedence over pedestrian access, you know a park is doomed to failure.
