When it rains, it pours.

And when it pours, stormwater flows, picking up debris, oil and toxic chemicals on roads, which ultimately pollute nearby waters.

Capturing this flow and making it work for communities is a challenge for urban planners and engineers. Enter green infrastructure: an engineering technique that mimics nature but is less costly than the traditional methods of building tunnels, drains and mains.

The green infrastructure approach redirects stormwater into the soil through porous pavements, shrubbery on rooftops or sunken grassy areas along the edges of roads and parking...
