Grasses Grab Pollutants
Lawns and rain gardens work together to keep stormwater on site and remove pollutants that would otherwise flow into storm drains or streams. The lawn portion of our rain garden shows runoff, intercepts sediment, and holds the soil to prevent erosion. The rest of the rain garden is planted with ornamental grasses and sedges adapted to thrive in soils that are sometimes saturated. In this part fo the garden, stormwater slowly percolates into the soil. |
