Analisis Konteks
The Pacific coastline at the United States-Mexico border is at the terminus of the Tijuana River Watershed. This binational watershed covers 1,740 square miles, 75% of which are in Mexico and 25% in the United States. The watershed’s coastal area contains two protected areas totaling 18,987 acres of some of the most ecologically significant salt marsh and coastal sage scrub ecosystems in California. These protected areas offer needed nature-based recreation for local communities, among the lowest-income and most park poor in San Diego County. Ecosystems and public health in border communities are threatened by Tijuana-generated plastics transported by the Tijuana River to coastal areas and the Pacific Ocean. An estimated 65,000 residents of Los Laureles, a tributary stream of the Tijuana River, generate approximately 54,740 tons of solid waste a day, of which less than 2% is collected by Tijuana’s Public Services Agency. The remaining is abandoned on the banks of the tributary.

In 2021, WILDCOAST will install the first-ever plastic retention system on the Mexico side of the Tijuana River Watershed. This Brute Boom will be installed in Los Laureles Canyon, a tributary stream and significant trash source for the Tijuana River. The system consists of a heavy-duty containment barrier designed to capture and contain floating and submerged trash before it enters the river. WILDCOAST and local partners are installing the system in a cement sediment basin on the canyon floor.
Waste collected by the system will be sorted, disposed, and recycled and repurposed where possible. Usable plastics will be provided to local projects such as community parks. Local partners will help in the sorting and removal of captured waste. The system will help remove up to 25% of plastic debris from entering the Tijuana River.
Meanwhile, WILDCOAST will launch a citywide communications campaign with local spokespersons to promote reducing consumption of single use plastics in Tijuana.

WILDCOAST’s solution involves the following activities to reduce ocean-bound plastic pollution:
- Capturing approximately 144,000 cubic feet of plastics via the installation of a trash boom (Brute Boom) in Los Laureles Canyon, Mexico.
- Collecting, sorting, disposing, recycling, and repurposing captured plastics.
- Using intercepted plastic waste as building materials for community-based projects including community parks.
- Developing and implementing a city-wide outreach and communications campaign to encourage communities in Tijuana to transition away from using single-use plastics, reaching an estimated audience of one million.
Previously installed trash booms and outlet screens in the Tijuana River Watershed (United States) are efficient at capturing floating trash once it enters the river, yet are insufficient to capture submerged trash. WILDCOAST’s installation of the more advanced boom in Los Laureles Canyon is capable of capturing both floating and submerged trash and will result in up to 25% reduction of plastic debris reaching the river and eventually the Pacific Ocean.
The primary challenge encountered was obtaining the buy-in and necessary permits to install the boom. Permitting and installation were further delayed by COVID-19. Government officials were subject to reduced hours and office closures which slowed the permitting process. Additionally, the installation of the Brute Boom, originally scheduled for December 2020, was delayed due to safety concerns regarding COVID-19. Meetings with community members were delayed. WILDCOAST remained diligent in following up with officials and partners, and followed strict COVID-19 safety protocol. WILDCOAST obtained all necessary permits and installation of the boom is scheduled for January 2021.

WILDCOAST’s Brute Boom was adopted by the City of Tijuana, Mexico's federal water authority (CONAGUA), local communities, and NGOs in the United States and Mexico. The City of Tijuana and CONAGUA demonstrated full support for the project by issuing permits for the installation and use of the trash boom. Initial behavior change from local community members has been demonstrated by the attendance of dozens of residents at community forums and site tours.
WILDCOAST is measuring behavior change in regard to plastic consumption and recycling, like changes of household waste practices, through pre and post surveys.
Additional metrics of success will include the passage of a statewide single-use plastic ban, a reduction in the amount of plastics entering the river, and a reduction in the amount of plastic reaching the Pacific Ocean from the Tijuana River.

The inadequate disposal of residential solid waste in Los Laureles leads to water, land, and air contamination, threatens life and property from flooding, degrades habitats, and affects open space for communities locally and downstream in San Diego County. Less than 2% of the trash generated in Los Laureles is collected by Tijuana’s Public Services Agency. Residents of this area live below the poverty line and do not have access to services unless provided by the government.
WILDCOAST’s project provides solutions to equity challenges by: 1) Increasing government-sponsored public services such as trash infrastructure, services, and recycling; 2) Improving public health by decreasing water pollution; 3) Increasing recreational opportunities along the Tijuana River Watershed on both sides of the U.S.-Mexico border; 4) Using captured plastics as the building blocks for new community buildings; and, 5) Beautifying the region through trash reduction and local art.
Apa sajakah manfaat tambahan lingkungan?
The Tijuana River National Estuarine Research Reserve and State Marine Conservation Area, together comprising 18,987 acres, are downstream from Los Laureles and are known for their biodiversity and high levels of endemism. The endangered flora and fauna of this area will benefit from decreased pollution of the Tijuana River. The TRW is also home to important blue carbon ecosystems, which when properly conserved help sequester atmospheric carbon and act as a natural solution to climate change.
Apa sajakah manfaat tambahan dari pembangunan berkelanjutan?
WILDCOAST successfully advocated for a single-use plastics ban in Tijuana and is meeting with elected officials in Mexico to discuss a state-wide ban, as well as increased government-sponsored public services. Under this model, residents will have increased access to improved trash infrastructure, services, and recycling. Many residents live below the poverty level and private services are either non-existent or too expensive, so this approach provides the most economically sustainable solution.

This project relies on a combination of grant funding and individual giving. The Benioff Ocean Initiative and University of California Santa Barbara have provided three years of funding to implement the project (beginning in 2020). Strategic partnerships, such as with 4Walls and PASA, allow for sustainable ongoing maintenance and use of the boom. Additionally, WILDCOAST engages local community members to sort and discard, recycle, or repurpose plastics collected in the Brute Boom. By recycling or repurposing and selling collected trash, the local community will have access to market-based revenue to increase economic gains within the community while reducing plastic and debris into the river.

Therefore, the services offered by the project site are between $94,935,000 per year if the ecosystem remains degraded to upwards of $1,329,090,048 if properly restored and managed. Combined with the public health and social benefits, this project is worth the moderate upfront costs.
Bagaimana kita bisa berhasil mereplikasi solusi ini di tempat lain?
Trash booms have previously been installed in the Tijuana River Watershed and elsewhere to reduce the amount of plastics reaching the ocean. WILDCOAST’s project provides a novel and more successful solution by utilizing an approach combining behavior change, policy change, and the installation of an advanced Brute Boom trash capture system. This project is replicable elsewhere, with appropriate funding (~$70,000 in one time initial costs and $15,000 in ongoing annual costs), partnerships, and government support.
Key components for replication include:
- A feasibility assessment to determine appropriate placement of the trash boom.
- Funding for the design, manufacture, and installation of the boom.
- Company to remove plastic from boom (4x monthly during this project).
- Buy in from elected officials to support single-use plastic bans and increased public services.
- Buy in from community members to reduce use of single-use plastics and increase recycling efforts.
