Southern California coastal cliffs could retreat 135 feet in 80 years as erosion rates potentially double
USGS scientists combined a series of computer models to forecast cliff erosion along the Southern California coast.
The research showed that for the highest sea-level rise considered by the paper (2 meters, or about 6 ½ feet), bluff tops along nearly 300 miles of Southern California coast could lose an average of 135 feet by 2100—and much more in some areas. Coastal managers could be faced with a difficult decision to prioritize bluff-top property or public beaches by permitting or prohibiting armoring. Learn more in a USGS news release posted July 9.
