Water from your neighborhood enters the storm drain system and flows directly to local creeks and the Bay without any treatment. Pollutants make their way into the storm drains when carried by rain or other runoff, becoming the leading cause of water pollution in the San Francisco Bay.You may be polluting the Bay without realizing it as most storm water pollutants often come from sources such as:
• Motor oil and leaks and other automotive fluids
• Antifreeze, oil, paint or household cleaners dumped or rinsed into the gutter
• Soap and dirt from washing cars in the driveway or street
• Litter and trash debris from overfilled solid waste containers
• Weed killers, fertilizers and pesticides that are washed off lawns
• Soil from construction or landscaping that erodes or blows into the street
Help Prevent Localized Flooding in your Neighborhood
- Don't blow leaves and yard debris into the street where it can clog catch basin inlets
- Removed parked vehicles from the street on sweeping days to enable the sweeper to reach the gutter line.
For information on how to prevent storm water pollution and storm drain clogging, visit the Watershed Watch website.
