The first rain gardens were created to mimic the natural water retention areas that developed before urbanization occurred. The rain gardens for residential use were developed in 1990 in Prince George's County, Maryland, when Dick Brinker, a developer building a new housing subdivision had the idea to replace the traditional best management practices (BMP) pond with a bioretention area.
The self-closing flood barrier (SCFB) is a flood defense system designed to protect people and property from inland waterway floods caused by heavy rainfall, gales, or rapid melting snow. [ citation needed ] The SCFB can be built to protect residential properties and whole communities, as well as industrial or other strategic areas.
Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
A green roof installed at Chicago City Hall Rain garden. Low-impact development (LID) is a term used in Canada and the United States to describe a land planning and engineering design approach to manage stormwater runoff as part of green infrastructure. LID emphasizes conservation and use of on-site natural features to protect water quality.
The New York City Department of Environmental Protection (NYC DEP) has built more than 11,000 curbside bioswales, which are referred to as 'rain gardens'. [18] Rain gardens are constructed throughout the city to manage storm water and to improve the water quality of city waterways. [19] The care and tending of rain gardens is a partnership ...
Rain Gardens are shallow depressions filled with an engineered soil mix that supports vegetative growth. They are usually used on individual home lots to capture roof runoff. Typical soil depths range from 6 to 18 inches. The capture ratio is the ratio of the rain garden's area to the impervious area that drains onto it.
In undisturbed areas with natural subsurface drainage, soil and rock fragments choke karst openings thereby being a self-limitation to the growth of openings. [13]: 189–190, 196 The undisturbed karst drainage system becomes balanced with the climate so it can drain the water produced by most storms. However, problems occur when the landscape ...
A bioretention cell, also called a rain garden, in the United States. It is designed to treat polluted stormwater runoff from an adjacent parking lot. Plants are in winter dormancy. Bioretention is the process in which contaminants and sedimentation are removed from stormwater runoff. The main objective of the bioretention cell is to attenuate ...
