A dune separating the town from the ocean has been growing in recent years, making sea level rise less of a concern, he said.
The report was commissioned by states and federal agencies looking for detailed information so they can plan for an accelerated rate of erosion along beaches, bluffs and sand dunes that are already crumbling into the sea. In Oregon, Greg Sieglitz, a monitoring program manager at the state Watershed Enhancement Board, said they helped sponsor the study to help them evaluate land purchases of coastal wetlands.
The report differed slightly from projections currently used by California officials, with the newer study estimating lower sea levels in 2100. The study summarized published projections and updated it with an analysis of tidal gauge readings and satellite measurements along specific sites on the West Coast.
Susan Hansch, chief deputy director of the California Coastal Commission, said that "a lot of the data we had before was worldwide data or has the caveat, 'Can't be used for planning purposes."
"It all comes down to the better data you have, the better decisions you can make," she said.
