C3 Presents Faces Grant Park Restoration After 400,000-Fan Lollapalooza 2026

Grant Park entered cleanup mode Monday after Lollapalooza drew an estimated 400,000 fans over four days, with rain leaving acres of churned-up grass and muddy festival grounds.
C3 Presents must now work with the Chicago Park District on a damage assessment within a week and agree on a remediation plan covering grass, plantings, fencing and surrounding public areas.
City officials reported 10 arrests, 0 tickets and 67 hospital trips during the festival, while Mayor Brandon Johnson still called the weekend a success because of the tourism boost.
A 2011 mud-soaked Lollapalooza cost $1 million to restore, and advocates say repeated damage underscores the need for longer-term drainage and flood-control upgrades that were not included in the current contract.
