The application, submitted to the City Council on Oct. 14 by a limited liability company tied to the Salt Shed, outlines development at 1401-59 N. Magnolia Ave. The Salt Shed’s owners, Blue Star Properties and hospitality group 16” on Center, do not own the property, and the proposal would move forward only if a sale is completed. The companies did not respond to a request for comment.

The site plan places about 100 parking spaces for attendees and artists near West Le Moyne Street, alongside offices and artist dressing rooms. The amphitheater would sit near West Blackhawk Street, with a stage, VIP seating, a general-admission standing area, tiered seating and a bar.

Plans also envision turning West Blackhawk Street into a landscaped public plaza linking the two venues, with a pedestrian bridge shown over part of the street. The street is already closed during Salt Shed shows for security and entry lines.

The proposed site covers about 516,316 square feet along the river’s east bank. The lots are sometimes used for event parking. The application does not state how many people the new amphitheater could hold; a 2025 report by Crain’s Chicago Business said it could accommodate as many as 15,000.

The Salt Shed, a concert venue in the former Morton Salt factory, holds about 5,500 people for outdoor shows and 3,600 indoors. Its owners have been developing a broader entertainment destination at the site, which includes food trucks and retail offerings such as a record store, guitar shop and tattoo parlor.

The proposal would add to the conversion of industrial properties along the North Branch into entertainment and other uses. The zoning application lays out a vision, but a land sale and city approvals remain necessary before construction could proceed.
