Sea level rise, and its perils, is often associated with the East Coast. But California communities along the coast that don’t prepare for what’s ahead could be inviting disasters of the magnitude not yet seen in the state.

A report by the United States Geological Survey Climate Impacts and Coastal Processes Team suggests that future sea level rise, in combination with major storms like the ones the state is experiencing now, could cause more damage than wildfires and earthquakes.

This is the first study that looks not just at sea level rise in California, but also sea level rise, along with a major storm to assess total risk to coastal communities.

“Even the storms today have significant risk to California’s coastline,” said Patrick Barnard, the lead author of the study. “There are about $12 billion in properties that are at risk of extreme storm today, but if you look out into the future, let’s say mid-century, those numbers roughly triple to about $30 billion of property at risk with just a little bit of sea level rise, and it goes up from there.”

The intent of the study is to educate communities that as storms pose a threat today, that threat will be amplified with the effects of sea level rise brought about by climate change. The report aims to give communities the ability to assess possible outcomes and, it is hoped, begin to take steps toward mitigation.
