Click on the video above to see Brad Lancaster show how native food-bearing trees and understory vegetation planted within or beside passive rain- and stormwater-harvesting rain gardens is able to shade and cool the neighborhood street by over 38˚F or 21˚C!
This is also a great flood-control system in wet times; mitigates drought in dry times; and improves our air, mood, and wildlife habitat all the time.
We are able to harvest over one million gallons of street runoff per mile per year from our neighborhood streets by directing that water to sufficiently sized rain gardens, rather than the storm drain!
This was filmed September 2022 in the Dunbar/Spring Neighborhood of Tucson, AZ
