Cross-border Cleanup
The Pacific coastline at the United States-Mexico border is at the terminus of the Tijuana River Watershed, which harbors some of the most ecologically significant protected coastal and marine ecosystems in the Californias. In Tijuana, Mexico, uncollected plastics and dumping in canyons and ravines contribute significantly to cross-border ocean-bound plastic debris.

In 2021, WILDCOAST installed the first solid waste retention system (trash boom) in Mexico in Los Laureles Canyon, Tijuana, Mexico. The trash boom has prevented more than 250,000 pounds of trash from entering the Tijuana River and, from there, the Pacific Ocean. Recognizing the success of that pilot project, leaders in other communities are advocating for trash booms. MDF is providing funding to install additional trash booms and to support an outreach campaign with residents and decision- makers of San Diego and Tijuana to change attitudes and practices around single use-plastics.
