Construction of the bioswale on Ashely Street is complete, just in time for a rainfall event!
What’s the difference between the before and after?It’s all in what you DON’T see.Much of the existing materials were excavated and replaced with an engineered soil mix. The soil mix will filter the stormwater runoff from smaller storms, removing sediment, oil, grease, and excess nutrients.Most of our rainfall events are smaller storms, therefore most of the runoff will be treated.Runoff from large events will flow into the area inlet. Native grass seed was sown in the bioswale.Native grasses are more suited to the Missouri weather extremes.Additionally, native grasses tend to be more deeply rooted encouraging infiltration and filtration of the runoff.
