GRANT PARK — With the bands and hordes of music lovers gone, all that's left of Lollapalooza 2015 is a torn-up park and a big clean-up bill.

Lolla promoter C3 Presents will pay $236,223.48 to repair Grant Park following the three-day festival that ended earlier this month, the Chicago Park District said Friday. Work is underway now and is expected to last through the third week of September at the latest, park district spokeswoman Jessica Maxey-Faulkner said.

C3 is shouldering all clean-up costs following the festival, which was the 10th Lolla held in Grant Park.

The park is expected to fully reopen by the end of September, Maxey-Faulkner said. Until then, certain areas of Grant Park will be cordoned off to visitors, but regularly scheduled events and activities in "Chicago's front yard" will not be disrupted.
