What is green stormwater infrastructure?

Green stormwater infrastructure utilizes plants, trees, and other measures to mimic natural processes that control and treat stormwater before it enters creeks, streams, and rivers. Green stormwater infrastructure includes practices such as vegetated roofs, bioretention, tree planting, permeable pavement, and rainwater harvesting that aim to intercept, evaporate, transpire, filter, infiltrate, capture, and reuse stormwater. 

Some examples of green stormwater infrastructure projects completed by the City include the vegetated green roof on City Hall, the bioretention filter at Charlottesville High School, and the constructed wetlands in Azalea Park. Check out the CityGreen Map to see these and many more examples!
