Mix together live music, great food, fireworks and thousands of your friends and neighbors, and you get the 21st annual Powell Festival.

Organizers expect about 15,000 people to attend the fest, slated June 22 and 23 at the Powell Village Green, 47 Hall St.

Six local bands will take the stage throughout the weekend and more than 75 vendors and exhibitors are expected, said Megan Canavan, city spokeswoman.

"We always say it's the city's signature event of the year. It has steadily been growing, and we're very grateful for that," Canavan said. "It's a great weekend to get neighbors together."

Admission is free.

The weekend will be capped off with fireworks about 10 p.m. June 23.

An expanded marketplace area, more food trucks and a mobile escape room are among new offerings this year.

Everything from pierogis and Caribbean food to the Cousins Maine Lobster truck is rolling into Powell to feed festivalgoers.

Food and beverages – including beer and wine – will be available for purchase, and there will be a "very robust" kids area that requires a $10 wristband, Canavan said.

The Mount Carmel Kids Zone will include a zip line, trampolines, obstacle courses and other items aimed at older children. A separate area with playsets, inflatables and activities aimed at toddler-age children will be free, Canavan said.

"We have quite a bit of artisan vendors, which is something different this year," she said, "and we always put a lot of focus on kids activities. Bring a chair or blanket for the lawn for the amphitheater so you can enjoy the music there."

The festival is not city-funded and relies heavily on volunteer groups, Canavan said.

About 100 volunteers from Powell-based Boy Scout Troop 428 will help with cleanup and setup.

"It's 'leave no trace;' the idea of a Boy Scout campout is to go over and over until not one little piece of trash is present there and to leave it better than we found it," said Jon Warrick, who volunteers with the troop. "So at the end of Sunday, when people are walking through the park, they feel like there wasn't a festival there at all."

The Powell Sertoma Club and Powell Citizen Police Academy also are vital to helping the festival run smoothly, Canavan said.

The festival's hours are 5 to 11 p.m. June 22 and noon to 11 p.m. June 23.

South Liberty Street will be closed to northbound traffic from 4 p.m. to midnight June 22 and again from 11 a.m. to midnight June 23.

Parking is available in public lots downtown and at Village Academy, 284 Liberty St.
