Parking lots and roadways contribute to the increase
in stormwater runoff, sediment, and contaminants
conveyed to our local waterways. The increased
stormwater runoff leads to flooding, erosion, and a
decrease in water quality in our lakes and streams. The
reflection and absorption of heat on our paved surfaces,
causing a heat island effect, can lead to issues such as;
increased energy consumption, elevated emissions of
air pollutants and greenhouse gases, and compromised
human health and comfort.
What is Green Infrastructure?
Green infrastructure is an approach that communities
can choose to maintain healthy waters, provide multiple
environmental benefits, and support sustainable
What are the benefits of Green
- Permeable Pavement and Stormwater Tree Vaults can:
- Intercept rainfall,
- Intercept parking lot runoff,
- Filter runoff pollutants,
- Reduce the urban heat island by providing shade,
- Promote beautification.
Both of these demonstrated Green Infrastructure
components work together to capture and treat
stormwater runoff before it enters the local waterways.
The retained rainfall waters the plants and trees, soaks
into the groundwater table naturally, and reduces storm
Why are Green Infrastructure
This project demonstrates how Green Infrastructure
measures like permeable pavements and stormwater
tree vaults might be incorporated into other public and
private parking lots and achieve multiple benefits.
