Briefings

A 2026 study using lidar technology identified specific areas in California's coastal cliffs where erosion is most active, posing risks to critical infrastructure including highways, railways, homes, and public access points. The evidence indicates that ongoing geological forces like rain and waves are actively reshaping these cliffs, with the study's findings providing a snapshot of current conditions rather than long-term forecasts.

Key points

• Lidar technology was used to identify specific hot spots for cliff erosion in California's coastline.
• The erosion process is driven by rain, waves, and other geologic forces that continuously reshape the cliffs.

Context

California's coastline is under constant threat from erosion, which endangers critical infrastructure such as highways, railways, homes, parklands, and public access points. This study provides a snapshot of current erosion hot spots using lidar technology.

Limitations

The evidence is limited to a 2026 lidar study snapshot and does not include historical data, long-term forecasts, or specific geographic coordinates. The study identifies hot spots but does not quantify erosion rates or provide a timeline for future impacts.
