California-Baja California Border Resiliency Plan

The California-Baja California Border Resiliency Plan (BRP) is a binational effort to study how climate stressors are impacting border region communities and ways for crossborder transportation infrastructure to better adapt to those conditions.

Climate stressors, such as rising heat, precipitation, and extreme weather events, have disproportionately impacted communities within the California-Baja California border region due to underdeveloped infrastructure. These kinds of environmental pressures can exacerbate air and water quality issues that currently exist, resulting in adverse public health impacts.

The California-Baja California BRP will study these conditions and identify strategies, programs, and projects that will help enhance and protect transportation infrastructure and the people who depend on it.

The study area is 10 miles north and south of the international border, from the Pacific Ocean east to the California-Arizona state border.

The study began in spring 2025. We expect to release a draft plan in summer 2026, and a final plan in June 2027.

The California-Baja California BRP is being developed with input from community, business, nonprofit, tribal, and government organizations in the U.S. and Mexico to ensure that projects, programs, and strategies will address the unique climate stressors, vulnerabilities, and challenges affecting those who live, work, and play in the California-Baja California border region.

The BRP will be managed by SANDAG, with input from Caltrans, the Southern California Association of Governments (SCAG), the State of Baja California, and the Interagency Task Force. The SANDAG Borders Committee will oversee the development of the BRP and will be responsible for final approval.

The California-Baja California BRP is funded through a $3 million Climate Adaptation Planning Grant provided by Caltrans.
