About
San Diego's oldest environmental nonprofit, founded in 1954. Best known for organizing the annual Creek to Bay Cleanup each April — the largest single-day cleanup in San Diego County — and Coastal Cleanup Day each September. Coordinates hundreds of volunteer events throughout the year at beaches, rivers, and canyons across the county. Particularly relevant for plant lovers interested in restoring native habitat and keeping San Diego's waterways and open spaces clean.
