Trash Free Waterways

Most people are surprised to learn that stormwater is a leading cause of water pollution across the country. Most stormwater is NOT treated before it enters the creeks or ocean; whatever material the water collects as it runs off is transported directly to our creeks or ocean.

The County of San Luis Obispo is committed to reducing the volume of trash reaching our waterways through the storm drain network. Learn more about the County’s efforts and how you can help!
