Discharges from individual residences are a factor contributing to water pollution during both the rainy and dry seasons. It’s up to us all to make sure litter, pesticides, detergents, oil, grease, and pet waste do not end up polluting our local waters. We can work together to prevent harmful substances from entering the storm drains and compromising water quality by keeping yards, driveways, sidewalks, and streets clean throughout the year. While rain and runoff is act as a conduit to transfer polluted materials into our waterways, our actions during the dry season often generate the material that causes the pollution.
Residents can help protect water quality in our creeks by following these good housekeeping best management practices (BMPs).
Driveways and Sidewalks
- Sweep off driveways and sidewalks rather than hosing them down. Dispose of the collected material in trash bins. Hosing down your driveway is also now illegal in California with new water conservation regulations.
- Cover any stockpiles of dirt or mulch before it rains or gets windy. Even when it isn’t raining bark, dirt, and other material can be blow from storage locations into local creeks or storm drains.
