Mason has rain gardens on both Fairfax Campus and Science and Technology Campus. Each rain garden is composed of a variety of native perennial plant species, which require minimal maintenance (wildflowers, shrubs and small trees). Rain gardens allow the storm water to penetrate into the ground and restore the water table, while simultaneously removing pollutants.
Some rain gardens are interconnected series. Water typically flows in and excess water flows out to the street or to a connected cell or other stormwater control. There are several bioretention of this kind in Science and Technology Campus. They are located along the parking lot at Hylton Performance Arts Center.
