31st Street Harbor
Chicago, IL
31st Street Harbor is the newest addition to the Chicago harbor system. Completed in 2012 with slips for 1000 boats and a sustainable, eco-friendly design, it provides an exceptional experience for boaters.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
