Bioswales channel stormwater into a trough filled with vegetation, compost or mulch, and rubble to reduce runoff, increase infiltration, and remove pollutants. Bioswales are often positioned alongside roads and parking lots to capture runoff. Bioswales often cost less than traditional curb and gutter systems, though their efficacy is dependent on proper siting, design, and construction, as well as continued maintenance. Vegetation used in bioswales should be flood tolerant, erosion resistant, salt tolerant, and native when possible. Bioswales can be used in combination with other stormwater best management practices to manage high stormwater flows.
Regular maintenance is required to ensure continued effectiveness and system longevity, including regular mowing and reseeding, as well as inspections for erosion, weed control, and trash removal. Proper snow and sand removal are necessary to ensure that bioswales continue functioning after winters in cold areas.
