AUSTIN (KXAN) – The 2012 Austin City Limits Music Festival is history, and now the cleaning-up-and-clearing-out phase takes center stage.

The weekend crowds combined with a round of rain took a toll on the Zilker Park lawn and crews spent Monday trying to put it back together.

After the festival ended, out-of town visitors headed to Austin-Bergstrom International Airport , some sporting their wristbands still in place. Airport officials sent out a warning to all travelers to arrive to their departure terminals at least two hours in advance.

“This morning, we did have about a 40-minute wait,” said Jason Zielinski, a spokesman for ABIA. “It came at different time periods but so far things are going smoothly.”

Travelers not taking part in ACL say they were still met with a surprise when they arrived to the airport this morning.

“I did pull up this morning wondering why there were so many people checking in,” said Austinite Debra Smith, a frequent flyer.

But the main job was just getting under way at Zilker Park where renovations were at full speed. Crews worked around the clock to break down the stages and pick up tons of trash left behind.

“The work is far from done we have crews out here taking down the tents and taking down the stages one piece at a time just the way they went up,” said Lindsay Hoffman, of C3 Presents , the company that organizes the music festival.

This year the festival took a more eco-friendly approach using high-tech trash cans powered by solar energy. Organizers also set up an entire recycling campaign to reduce the amount of trash.

“This year, we filled 227,000 bottles of water, so that is 227,000 bottles of water that we diverted from the landfill,” said Hoffman.

Austin-Travis County Emergency Medical Services reported that 60 people were transported to local hospitals for an assortment of nonlife-threatening ailments.

Most were alcohol and drug-related, many of those treated were underage, police said. The heat likely played a part in some of the incidents, although heat has been a much bigger factor in some previous years when the temperatures were higher.

Overall event organizers are calling ACL 2012 a success. Reservations for tickets to next year’s music fest are already underway with “early bird” sales starting Oct. 30.

Crews will be working well into the week to restore Zilker Park before the city’s Parks Department takes a full run through later this week.

The park is expected to reopen to the public on Friday.

While the trash, long lines and loud crowds left some Austinites ready for the festival to end, others say they’re just glad the festival helped put a charge into the local economy.

“It’s bringing in all kinds of revenue,” said Smith. “For the people who don’t like it they need to stay home and watch Longhorn football on television.”
