What is Green Stormwater
Infrastructure?
Green Stormwater Infrastructure, or GSI means infrastructure constructed with a range of measures that use plant or soil systems,
permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to the public storm drain system or to surface waters.
These features are also sometimes referred to as low impact development (LID). They are generally small in size to capture water where it falls for multiple co-benefits.
Examples include:
- Permeable pavement
- Curb openings
- Bioswales
- Stormwater harvesting basins
- Bioretention systems
- Curb extensions (chicanes)
