💧 Did you know that every waterway in our region is part of the Chesapeake Bay watershed? This means that what happens in our neighborhoods can have a lasting impact downstream!

Litter, pet waste, fertilizers, oil, and other pollutants can be carried by stormwater into our local streams and rivers—affecting our sources of drinking water, the homes of local wildlife, and the health of our environment.

The good news? Small actions can make a big difference. By keeping only rain down the storm drain, you can help protect the water we rely on every day.
