What are Bioswales? Bioswales are long channeled depression usually in parking lots or along streets that receive rainwater runoff and have vegetation, such as grasses and herbs, and organic matter, such as mulch. The vegetation and organic matter are what slows down water infiltration and filter out pollutants.

Benefits of Bioswales Protects local waterways from stormwater pollutants Creates habitat for wildlife, including birds and butterflies, Reduces non-point pollution by filtering stormwater Reduces standing water (puddles) that can attract mosquitoes Creates colorful gardens with a variety of flowers and plants year round Requires little maintenance after establishment

Rain Gardens Vs Bioswales Bioswales achieve the same goals as rain gardens by slowing and filtering stormwater Are designed to manage a specified amount of runoff from a large impervious area Require use of engineered soils and are deeper than rain gardens because they take in larger quantities of stormwater i

Best Locations Areas that have high impervious surfaces such as roads, parking lots, or rooftops. They can also be integrated into road medians, curb cutouts, sidewalks, or any public space.
