Bioretention Cells

-Comprised of several buffering layers including grass, sand, gravel, mulch, planting soil and plants. 

-Similar to raingardens which can be used to collect stormwater on a smaller scale in your yard!

-Vegetated depressions that collect runoff and facilitate its infiltration into the ground.

-Often found in parking lots and throughout large scale residential developments

-Utilize soils and various types of herbaceous vegetation to remove pollutants from stormwater runoff and reduce the flow from storm events. 

-Surface runoff from impermeable surfaces is directed into the cell 

-Runoff slowly percolates back into the surrounding ground area.
