More than 3,000 people have signed the online petition to keep Riot Fest in Humboldt Park.

Riot Fest organizers are encouraging supporters to write letters to Mayor Emanuel and Ald. Roberto Maldonado (26th) after the alderman said he doesn’t support the return of the three-day music festival.

In an emailed letter, music festival’s organizers urged supporters to go to the alderman’s office on Monday night.

The alderman and the festival organizers are at odds over whether the fest should come back to Humboldt Park after damage to park grounds lingered months after the September event.

As first reported by RedEye last week, the alderman said: “I am exceptionally disappointed at the Riot Fest organizers for the mess they left at the park last year and their shallow and hollow promises to restore the park. I don’t support them coming back.”

Riot Fest founder Michael Petryshyn in a statement issued Thursday said he was “extremely surprised” at Maldonado’s comments since the alderman supported the festival in the past.

Landscape repairs are currently underway. Riot Fest organizers said they were planning to meet this week with Maldonado to address his concerns and opposition.

However, Maldonado’s office said no meeting has been set up yet.
