The Gahanna Planning Commission is recommending to city council that a detention basin be expanded on dedicated parkland at Giant Eagle and Shagbark for stormwater management.

The commission unanimously approved a variance Aug. 24.

City engineer Karl Wetherholt said the 2.443-acre site is the property of the city, and it has an existing dry basin.

The proposed basin is a dry basin that would occupy about three-fourths of the parcel, with the rim of the existing basin suitable for a walking path.

The purpose of the expanded basin is to relieve flooding problems for property owners along McKenna Creek.

Wetherholt said the basin would divert high flows from the creek into the basin, where water would be detained for several hours.

"It's not an ideal solution, but it aids with flooding for downstream people," he said. "It's something we can do immediately and get results."

Wetherholt said Gahanna also is committed to working with the city of Columbus and upstream property owners in devising other solutions to help with water quality and stormwater management.
