CAMDEN City officials announced the creation of a "pop-up park" outside City Hall where lawn chairs, picnic tables, light installations, and a piano will remain available to the public through December.

The building and installation of the new amenities in Roosevelt Park cost $30,000 and were funded by the William Penn Foundation and created by Cooper's Ferry Partnership in conjunction with local design firms.

On Monday as Mayor Dana Redd and other city officials gathered in a tent to formally introduce the park, a half dozen people sat in the blue lawnchairs, chatting with friends or dozing on the breezy day: The park has been open for two weeks and many residents already had discovered it.

"This is part of a growing movement to revitalize by investing in public space," said Anthony Perno, CEO of Cooper's Ferry Partnership. The design, he said, is similar to that of Military Park in Newark and the outside of 30th Street Station in Philadelphia.

Large cubical planters and lighting units are stacked around the park, with canopies of white fabric overhead to shield visitors from the sun. The plastic lighting units - created from repurposed containers used in industry to store liquids - light up after dark and are equipped with motion sensors to change colors as people walk by.

"We hope this is home and hearth for people to come enjoy, break down barriers, and be together," said Bevin Weissman, of Philadelphia-based New American Public Art, which helped with the park's design.

Diane Cornejo stopped outside after a trip to City Hall with her 18-month-old daughter who played with a large children's ring game. "It's a good example of renewal," Cornejo said. "It's relaxing, peaceful."

Belinda Kellicker, 46, sat with her boyfriend Kareem Williams, 39. Kellicker, of Gloucester Township, is battling ovarian cancer and often comes to Cooper Medical Center for appointments. The couple has started going to the park afterward to decompress.

"We call it the blue seat park. It was nice on Sunday but I wouldn't bring my kids here during the week," Kellicker said, noting that many people from the nearby methadone clinic had come through earlier in the day.

"It's good that they also have somewhere to go but it's nicer on the weekends without that vibe," she said.

Joseph Meyers, vice president of Cooper's Ferry, said the area is open into the evening with security from Allied Barton patrolling as well as the city's Special Services District maintaining the space from 6:30 a.m. to 6:30 p.m. Monday to Saturday and on Sundays from noon to 4 p.m.

During lunch breaks on nice days Meyers said he's been unable to find anywhere to sit. "It's what we were hoping for," he said. "It's a good problem to have."
