Green Stormwater Infrastructure (GSI) is a type of urban greening Urban greening is a broad term for strategies that promote ecosystem health by introducing vegetation and natural features into urban places.
that takes advantage of the natural processes of soils and plants to manage stormwater Stormwater is rainwater that is produced by a storm.
, and also achieves many environmental and social benefits in the urban landscape. Rain gardens Rain gardens, or bioretention cells, are engineered sunken areas that manage stormwater runoff by filtering and infiltrating water, mimicking natural processes to reduce volume, delay runoff, and treat pollutants.
, rainwater harvesting systems, bioswales Bioswales, frequently situated alongside curbs and in parking lots, utilize vegetation or mulch to decelerate and purify stormwater runoff.
, and green streets and alleys are all examples of GSI.
