A scheme opens on Saturday that aims to prevent houses flooding in an area of Royal Leamington Spa.
A piece of land near Lillington Road has been hollowed out to allow water to drain during heavy rain.
The site, which has been named Midland Oak, also features a children's play area and newly-planted trees.
Dale Best, head of leisure and amenities at Warwick District Council, told Radio WM that residents have been putting up with flooding for some time.
"It's been an intermittent problem for 11 years. It's been worse in the last 2 or 3 years because we've had such wet weather," he said.
"It will take a large amount of water which otherwise would have gone on to the street, or even people's houses.
"I know a lot of people will be very grateful," Mr Best added.
