Couch Place alleyway is a functioning service alley where garbage is collected and messenger bicyclists shortcut. Yet instead of cement, the alley is covered with permeable concrete pavers that reflect heat and reduce storm-water runoff, thereby preventing nearby properties from flooding and reducing the need for additional sewer infrastructure. The effect is a backstage area that’s bright, clean, and eco- and pedestrian-friendly. In addition, periodically throughout the year this alley turns into a place-making experience by transforming into a pop-up art gallery, used to celebrate art, music, fashion, design, and technology. It is Chicago's first "People Alley" public space.
