Stormwater; an economic resource

Stormwater is a big problem for cities—and a growing one. Lots of urban surface area is impermeable, so stormwater can’t sink into the ground but instead flows through the city. Meanwhile, climate change is altering and often intensifying rainfall and precipitation patterns.

Enter green infrastructure: natural areas that can capture, store, and filter stormwater, provide habitat and other benefits, and help cities comply with water quality laws and regulations.
