The Northern California Bay Area faces significant challenges from climate change. Storms hit the coast hard, tides flood the streets, and wildfires rage through the forests. Compounding these issues, the ocean’s rising levels are pushing waters into the bay, while land sinking due to soil compaction is making matters worse.
By 2050, NASA projects that sea levels in California could rise by 6 to 14.5 inches, with some areas like San Rafael expecting an even steeper increase of over 17 inches within the next 25 years. This is particularly concerning for low-lying neighborhoods, especially the Canal area, home to many Latino residents.
In response, California initiated the Regional Shoreline Adaptation Plans (RSAP) in 2023. These plans aim to build resilience against rising water levels and support coastal communities. San Rafael has launched the Sea Level Rise Collaborative Project (SLRCP) to address local impacts.
“Sea level rise in San Rafael is a major concern,” said Chris Cogo, an environmental justice advocate working with the SLRCP. The city is open to various adaptive measures, like restoring marshlands, creating living seawalls, and reinforcing levees with vegetation to slow water flow. Rumors of relocating residents from flood zones have been dismissed by officials.
However, a novel idea has arisen—using AI-powered robots to lift sinking land in vulnerable areas. This method involved injecting a mixture of wood chips and water beneath the surface to elevate the land. Laurence Allen, co-founder of the company Terranova, calls it “like blowing up a balloon under a piece of paper” to raise the ground level.
Terranova believes that this technique could also help combat climate change by capturing carbon dioxide from the atmosphere. The company has mapped out areas at high risk of flooding in San Rafael using over 700,000 datasets. Over the past 50 years, some neighborhoods have sunk by more than 3 inches, exacerbating their vulnerability to flooding.
Despite this innovative approach, skepticism remains among city officials and residents. Kate Hagermann from San Rafael’s planning department expressed concerns about whether this technology is truly the best solution when considering existing infrastructure.
Local resident Rita Mazariegos emphasized the urgent need for solutions, recalling past floods that caused significant losses for community members. Terranova has reported interest from some city officials, yet the reception within the SLRCP has been lukewarm.
In other regions, such as Richmond, California, similar technology has gained more support. Vice Mayor Cesar Zepeda highlighted the importance of leveraging local resources to address flooding risks quickly. However, experts like Brian Snyder remind us that any innovative solution must be approached cautiously, especially in places prone to earthquakes.
Recent studies show that sea levels have increased by 0.14 inches per year, doubling the rate from previous decades. This rise has significant implications for the Bay Area, where thousands of properties are at risk. In San Rafael alone, projections estimate that more than 2,000 homes could be affected by rising waters by 2045.
Funding for climate initiatives has faced challenges, particularly with federal cuts to environmental programs. The Bay Area needs around $110 billion to effectively adapt to sea level rise, which could prevent costly damages in the future.

In the face of these challenges, community voices stress the need for immediate and effective action. Options exist, but the path forward requires collaboration and a commitment to innovative solutions.
