Stormwater and Water Quality

You can help keep local waterways healthy

Anything on a roof, driveway, parking lot, sidewalk, and even your lawn or garden can be washed into a storm drain.  It's up to all of us to connect the dots and keep pollution out of our waterways.  See our tips and resources below.
