Davenport Builds Detention Basin To Prevent Flash Flooding

After floods devastated neighborhoods near Duck Creek in 1990, officials took note. Now, the Littig Area Regional Detention Basin will help prevent flooding and cut down on erosion. On Monday, Dec. 2, 2013, Davenport city leaders introduced the detention area as a solution to devastating flash floods.

Davenport Natural Resources Manager Brian Stineman explained how the field off 61st. St. is now a huge bathtub that will fill and then slowly drain during big rain events.

"There's 227 acres of watershed that drain to this location. So if it rains an inch over that watershed, that generates about 1.5 million gallons of water that would ordinarily flow right through, just ripping as fast as it can go," Stineman said. "What this will do is slow that water down, detain it over time, some of it will be used by the plants, some of it will be stored here on the flood plain benches," he added.

Using a system of pipes, native trees and grasses, the detention basin can now slow down enough water equivalent to a 100 year flood event. Not only does it prevent personal property damage, but Stineman says it's also better for the environment, preventing erosion.

The basin slows water running into Goose Creek and eventually Duck Creek. Officials are looking into other locations for water detention, including the area that flows into Silver Creek. Stineman says while some private developers have created their own detention areas since the 1990 flash floods, this is the first city-built project.
