It might look like any other garden with mulch, stones and plants, but the bioswale at Springdale’s Recycling Drop-Off Center has secret powers: it acts like a sponge to reduce stormwater runoff and help keep stormwater clean.
The garden is actually a “biofiltration” basin constructed through a collaboration between Springdale and the Cooperative Extension Service, part of the University of Arkansas System Division of Agriculture. As a Tree City USA community, the Springdale project was supported by the Urban Forestry Program of the Arkansas Forestry Commission and the U.S. Forest Service.
“This is a great example of ‘green infrastructure,’” said Katie Teague, Washington County extension agent for the Division of Agriculture. “The basin collects, absorbs and filters stormwater. The amended soil mix is planted with native trees, shrubs, grasses and flowering perennials that also provide shade and habitat for wildlife.”
An interpretive sign explains the function and benefits of the basin.
“This demonstration promotes public understanding of green infrastructure. Residents visiting the recycling center can learn how they can better manage stormwater on their own property,” said Teague.
Water that is collected and filtered by the bioswale eventually runs into Spring Creek, part of the Illinois River Watershed.
