From the shores of San Diego to the vibrant coastlines of Tijuana and Playas de Rosarito, our communities are united by the ocean. But our coastlines face growing challenges—polluted waters, climate impacts, and fragile ecosystems that demand urgent attention. It’s time to come together, across borders, to protect what we all share.
One Coast, One Community is a transformative binational movement built on collaboration, community knowledge, and science. We’re not just raising awareness—we’re taking action to safeguard water quality, restore coastal resilience, and create a sustainable future for generations to come.
Value of Binational Collaboration
Our coastline is connected—and so are our communities. Pollution or coastal erosion in one region affects all of us. That’s why One Coast, One Community is founded on cross-border cooperation, uniting people from San Diego, Tijuana, and Playas de Rosarito in a shared mission.
What this means for you:
- Access to regional knowledge and resources that amplify impact
- Unified voices advocating for stronger environmental protections
- Culturally inclusive solutions that reflect the diversity of our coastline
When we work together, we go further—and we go stronger.
Science You Can Trust, Led by the People
We combine collaborative science with local insight to better understand and address coastal challenges. Our approach brings together researchers, community leaders, youth, and residents to collect data, test solutions, and drive real change.
What this means for you:
- Science made local—you don’t need a lab coat to make a difference
- Community-based data informs smarter policy and action
- Training and tools to empower citizen scientists and educators
We’re turning science into action—and turning community members into change-makers.
A Healthier Coastline Means a Healthier Community
Clean beaches and resilient shorelines aren’t just about nature—they’re about public health, jobs, and quality of life. From recreational opportunities to tourism and fisheries, our coast fuels our economies and well-being.
What this means for you:
- Safer beaches and cleaner water for your family
- Stronger coastal infrastructure to protect homes and livelihoods
- Revitalized ecosystems that support biodiversity and climate resilience
By restoring our coast, we’re investing in our collective future.
