Stormwater Shapes Our Story

We all live, work, and play in a watershed. You can help keep it clean and healthy by learning about stormwater and doing your part to prevent pollution.

Learn the Basics

From Your Home to the Creek

Common household activities can be sources of pollutants, which are picked up by rain and snow and carried through storm drains into our local creeks without being treated.

Steps stormwater takes from our homes to local waterways. Pollution from cars, pet waste, chemicals, and pesticides around our homes are picked up by rain. This rain enters nearby storm drains, which drain directly into local waterways.
