Designed to handle the flow of stormwater, Vegetated Bio-Swales accomplish the following:
A vegetated swale typically consists of a band of dense native vegetation, underlain by at least 24 inches of permeable soil.
The permeable soil media should have a minimum infiltration rate of 0.5 inches per hour and contain a high level of organic material to enhance pollutant removal.
A vegetated swale typically consists of a band of dense native vegetation with permeable soil to absorb stormwater and enhance pollutant removal.
The native vegetation can provide habitat for butterflies, birds, and other wildlife that are part of a balanced, biologically diverse ecosystem.
