Think about the last time it poured buckets of rain. Did you see sheets of water flowing down your driveway? Or streams of water gushing along the curb?
That’s stormwater.
Stormwater is water flowing from yards, parking lots, roofs, and other places when rain falls or snow melts.
You’re looking at stormwater--rainwater moving across the ground.
