Ever heard of the term “stormwater runoff”? It refers to rainfall that does not seep into the ground and instead flows over the ground surface and into our sewer or drainage systems. In urban and suburban areas, where there is an abundance of sidewalks, roads and other paved areas, stormwater management is becoming an increasingly complicated and costly problem. But, trees can help! Not only are they are a cost-effective way to reduce flooding, they also provide countless co-benefits such as shade, air purification, beauty and privacy.
