King Tides and Deluge Carve Into Butterfly Beach

The recent storm delivered a dramatic punch to Montecito’s shoreline, and nowhere was that more visible than at Butterfly Beach. The County of Santa Barbara rainfall sensor near Olive Mill and Hot Springs roads registered 11.40 inches of rain (year-to-date) on December 23; by the time the weather calmed on January 5, it read 20.87 inches — a staggering 9.47 inches of additional rainfall in under two weeks. 

That sustained deluge, paired with a sequence of winter King Tides, carved into the beach profile, exposing sections of the concrete access infrastructure fronting the Biltmore and Coral Casino. While erosion is expected during intense winter cycles, this year’s combination of rainfall, wave energy, and tidal extremes accelerated the process, leaving beachgoers with a visibly altered shoreline and prompting immediate assessment by public agencies and private property stewards.

Butterfly Beach falls under a patchwork of jurisdictions. The County Parks Department manages the public stairway at Channel Drive and Butterfly Lane, but the additional stairways farther east – those adjacent to the Biltmore and the Coral Casino – are privately managed by Ty Warner’s team. According to County Parks staff, inspectors surveyed their facilities following the storm and noted no damage at the publicly managed stairway. However, the privately owned access points experienced impacts tied directly to the wave run-up and weakened sand base. County Parks does not oversee repairs on these privately controlled structures, though staff indicated they would coordinate as needed to support safety and continuity of access.

More broadly, the erosion event has renewed questions about long-term coastal resilience along the Montecito and Santa Barbara shoreline. While each winter brings episodic sand loss, the intensity of recent storm seasons has drawn attention to regional sediment management planning, including the County-led BeachSMART program.

BeachSMART (Sediment Management and Resilience Tools) is designed to improve how Santa Barbara County understands and manages sediment across watersheds and the coast. The program focuses on natural processes, nature-based solutions, and long-term strategies to maintain beach health and shoreline stability. Its work includes studying existing sediment pathways, evaluating potential new sediment sources and receiver sites, and exploring alternative management techniques that could bolster beaches during increasingly volatile storm years. Local agencies, technical advisors, environmental groups, tribal partners, and community organizations all contribute to this effort, which is supported by the State Coastal Conservancy and led by the County Flood Control District. Though still in progress, BeachSMART represents an important shift toward coordinated, region-wide planning for beaches like Butterfly, where seasonal erosion is predictable but increasingly dramatic.

In the immediate aftermath of the latest storm, County Supervisor Roy Lee acknowledged both the scale of the weather event and the swift response underway. “The heavy rain combined with the King Tide caused some damage to the steps at Butterfly Beach,” Lee said. “County staff are already aware of the situation, and we will do whatever we can to help the Biltmore team. Hopefully, the repairs can be made quickly and safely. In the meantime, I want to remind folks to use caution near the damaged area while this gets fixed.” 

Ty Warner’s team mobilized quickly. As the MJ reached out, a bulldozer was already on site at Butterfly with construction crews working on remediation. 

A representative for Ty Warner noted that while the lower access steps sustained recent damage, they were temporarily exposed due to the storm-driven sand loss typical of winter months. “Today, Ty Warner generously covered the cost of a professional crew to remove broken concrete segments at Butterfly Beach, ensuring the area remains safe and accessible for the community,” the representative said. “As is typical during winter months – especially in years with heavier storm activity – sand naturally erodes from beaches and then returns in the spring and summer through seasonal coastal processes. The lower steps at Butterfly Beach have not been damaged; they have simply been exposed by winter erosion and are expected to be reburied naturally as sand levels rebuild in the coming months.

“We appreciate the community’s patience during this seasonal cycle and the proactive efforts taken today to address immediate concerns while respecting the natural rhythms of our coastline.”
