Stormwater
Natural drainage systems use surface features such as retention ponds, swales and open channels to capture stormwater runoff, creating a respite for people to enjoy, and a home for birds and wildlife. Courtyard gardens fed by roof water clean the storm water runoff from adjacent hardscape surfaces. The benefits are reduced costs associated with treatment facilities and subsurface systems, decreased irrigation needs, improved stormwater quality through biofiltration, and new opportunities for artistic expression.
