Chicago's most valuable natural asset is its lakefront, forever free, public, and protected by law. This lakefront is so valuable, argues the architects at Port Urbanism, that we need more of it to pay off the city's massive debts. Or (if you ask the designers at UrbanLab) newly built islands in the lake must be drafted into relieving pressure from an overstressed storm drain system by filtering and cleaning the city's water. Featured at the 2015 Chicago Architecture Biennial, Port Urbanism and UrbanLab's lakefront proposals offer infrastructural fixes to some of Chicago's most dire emergencies. They also colonize a near-sacred urban vista with varying degrees of public and private space; not the type of thing you can do without getting through some pretty contentious community town hall meetings. Hosted by Zach Mortice and Newcity Design Editor Ben Schulman, with guests Andrew Moddrell of Port Urbanism and Martin Felsen of UrbanLab. Special thanks to recording studio engineer Tim Joyce.
