San Diego to Vote on $150M Border Pollution Plan
Locales: UNITED STATES, MEXICO

SAN DIEGO, CA - February 3rd, 2026 - The San Diego County Board of Supervisors will today vote on a substantial funding package designed to address the escalating crisis of transboundary pollution plaguing the Tijuana River Valley. The proposal, years in the making, aims to move beyond reactive measures to implement comprehensive, long-term solutions to a problem that has impacted public health, the environment, and binational relations for decades.
The Tijuana River Valley has become synonymous with environmental degradation. Regularly, raw sewage, industrial waste, and stormwater runoff from Tijuana, Mexico, cross the border, overwhelming existing infrastructure and flowing into the river and, ultimately, the Pacific Ocean. This consistent flow of contaminants results in beach closures, poses significant health risks to residents on both sides of the border, and devastates the delicate ecosystem of the valley.
The proposed funding plan, totaling $150 million over the next five years, focuses on a three-pronged approach: infrastructure improvements, mitigation efforts, and collaborative partnerships. A significant portion of the funds--approximately $60 million--will be allocated to upgrading and expanding wastewater treatment facilities along the border. These upgrades will incorporate advanced treatment technologies capable of handling increased volumes and a wider range of contaminants. Another $40 million is earmarked for enhancing stormwater management systems, including the construction of retention basins and improved drainage channels, to prevent runoff from overwhelming the river during heavy rainfall events.
The remaining $50 million will be dedicated to habitat restoration projects, focusing on revitalizing damaged wetlands and riparian ecosystems within the Tijuana River Valley. These projects aim to improve water quality, enhance biodiversity, and provide natural buffers against future pollution events. The county recognizes the importance of not only stopping the pollution but also repairing the damage already inflicted.
"This isn't just an environmental issue; it's a public health crisis and an economic burden," stated Supervisor Terra Nova in a press briefing yesterday. "For too long, our communities have suffered from the consequences of this transboundary pollution. This plan is about protecting the health of our residents, preserving our natural resources, and holding ourselves accountable for finding a sustainable solution."
However, the plan isn't without its complexities. A crucial component of the initiative involves forging stronger partnerships with federal agencies, the State of California, and, crucially, Mexican authorities. The pollution originates in Mexico, and lasting solutions require a coordinated effort to address the root causes - aging infrastructure in Tijuana and insufficient investment in wastewater treatment. The county is actively negotiating Memoranda of Understanding (MOUs) with the Mexican government to share resources, expertise, and financial responsibility. The US International Boundary and Water Commission (IBWC) is expected to play a central role in coordinating these efforts.
Community groups have been instrumental in bringing attention to the pollution crisis and advocating for meaningful action. Groups like the "Clean Water Now" coalition have organized protests, conducted independent water quality testing, and lobbied elected officials for years. While welcoming the proposed funding plan, they emphasize the need for transparency and accountability. "We need to ensure that these funds are used effectively and efficiently, and that the projects are implemented in a timely manner," said Maria Rodriguez, a spokesperson for Clean Water Now. "We'll be closely monitoring the progress and advocating for continued investment until the problem is fully resolved."
Beach closures along the San Diego coastline, particularly Coronado and Imperial Beach, have become increasingly frequent in recent years, impacting tourism and recreational activities. The economic cost of these closures is substantial, with local businesses losing revenue and residents losing access to public beaches. The proposed plan seeks to minimize these closures by reducing the volume of contaminated water entering the ocean. Looking forward, supervisors have indicated plans to explore innovative technologies, such as advanced filtration systems and real-time monitoring networks, to further enhance pollution control efforts. The long-term vision includes a fully integrated wastewater management system that spans both sides of the border, ensuring a clean and healthy Tijuana River Valley for generations to come.
