Bluff Collapse at Brighton Beach Destroys Cabins, Threatens Homes
A late night bluff slide on December 18 at Brighton Beach in Old Clinton demolished multiple walk in beach cabins and left at least one house yellow tagged as too unsafe to inhabit. Island County officials say the bluff is unstable and warn residents and visitors to avoid the slide zone while assessments continue.

A sudden bluff collapse in the Brighton Beach area of Old Clinton on December 18 destroyed a two story blue cabin and heavily damaged several adjacent walk in beach cabins, leaving mud and debris across a narrow strip of shoreline and damaging a nearby boat house. County inspectors responded to the scene and issued a yellow tagged notice for at least one residence, indicating it is unsafe for habitation, and advised the public to stay away from the slide zone while work continues.
Island County Public Works Director Bill Oakes said county engineers have concluded the bluff is unstable and that recent slides appear to be driven by groundwater moving through the slope. A University of Washington geologist interviewed for this report explained the mechanism in technical terms, linking the slides to saturation of soils and to recharge areas located inland behind the bluff. The Brighton Beach area has long been mapped as geohazard prone, a designation that informs permitting and emergency response but does not prevent sudden collapses during high recharge events.
Neighbors and homeowners described a late night collapse that spread mud and woody debris across the beach and into structures. Several privately owned beach cabins were either destroyed or rendered uninhabitable, and homeowners are now confronting immediate safety concerns, potential insurance claims, and the loss of seasonal or primary living space. County crews and inspectors have used red tagged and yellow tagged notices to identify structures with imminent risk and to limit access to unstable portions of the shoreline.

Island County officials have warned that additional movement is possible while the bluff remains saturated, and they said inspections and monitoring will continue. The county also indicated it may re evaluate bluff stability and public access rules for the affected stretch of coast as conditions evolve, and it urged residents to follow posted warnings and avoid the slide area.
For Island County residents, the event underscores ongoing risk in mapped geohazard zones and raises questions about long term management of homes and infrastructure along aging bluffs. Local property owners and officials will need to coordinate on safety measures, insurance responses, and potential shore stabilization options as assessments proceed.
