A rockslide beneath the elevated beach stairs and viewpoint at Laguna Beach’s Agate Street access closed a route to the shoreline on September 29, 2026. Thankfully, the City of Laguna Beach reported no injuries. The city's Fire and Marine Safety crews responded and closed the access.
A rockslide directly beneath the beach stairs
Photographs published by the City of Laguna Beach show the substantial scale of the rockslide. Large sections of rock broke away from the bluff directly beneath the elevated stairway and viewing platform, leaving an exposed rock face and large fallen boulders below.
Coastal cliffs change through several processes. Waves can gradually remove material near a cliff's base, while natural fractures and the strength of the rock influence how the material above holds together. A rockslide occurs when rock moves downslope, sometimes in large blocks. Research by the U.S. Geological Survey identifies wave energy, beach width and elevation, and rock strength among the factors influencing coastal cliff erosion.
Recent shoreline conditions
The Agate Street incident occurred during a broader period of coastal erosion in Laguna Beach. According to the city's coastal preparedness information, swells from Hurricane Marie beginning September 2, 2026, carried substantial amounts of sand away from local beaches and contributed to ongoing erosion. The city proclaimed a local emergency on September 10, which the City Council ratified on September 14.
The amount of sand along a beach can influence how much wave energy reaches the cliffs behind it. When a beach becomes narrower or lower, waves may reach the base of the bluff more frequently, increasing its exposure to erosion. These conditions provide useful context for understanding coastal change, although they do not establish the cause of the Agate Street rockslide.
The city's response
Following the rockslide, the City of Laguna Beach announced that a geologist would survey the affected area. The city also directed the public to stay away from the site and observe posted closures during the evaluation.
