First Rock Baptist Church Rain Garden

First Rock Baptist Church Rain Garden. A Tool for Stormwater Management. , Stormwater runoff is rainwater that flows off impervious surfaces such as rooftops, roads, and sidewalks. Runoff causes erosion in streambeds and displaces harmful pollutants such as oil, sediment, trash, and pet waste. This rain garden is capturing and infiltrating stormwater runoff that would otherwise run directly to Rock Creek and then eventually into the Potomac River., The First Rock Baptist Church rain garden and BayScape were completed in the Fall of 2014. This 150 square foot rain garden captures and treats runoff from 1,872 square feet of rooftop. With an average annual precipitation of 42 inches, the garden will capture around 1,416.5 gallons of stormwater each 1.2" rain event, and around 42,833 gallons each year. This garden is planted with native plants that tolerate both wet conditions and periods of drought.
