stormwater
We all know what LA looks like when it rains hard. Think of streets turning into streams, waterfalls cascading down sidewalks, and canoes cruising down boulevards. Okay, maybe not that last one, but you get the idea.
All that stormwater not only looks gross, but it can also cause flooding and destruction. Even worse, this dirty water flows to the LA River, polluting the water and harming flora and fauna!
