California’s iconic piers, symbols of coastal culture and history, are increasingly imperiled by climate change. As reported by Noah Haggerty, recent storms, including those that severely damaged Santa Cruz Wharf and Ocean Beach Pier, have highlighted the vulnerabilities of these aging structures to intensifying storm patterns, rising sea levels, and unpredictable weather events. Despite ongoing efforts to reinforce piers with structural upgrades, the challenges of climate change are outpacing these interventions. Scientists warn that shifts in storm direction, fueled by warming temperatures, are striking even sheltered piers, creating an urgent need for strategic planning and resource allocation to preserve these landmarks.

The costs of maintaining and upgrading piers are steep, with repairs often running into millions of dollars and leaving piers closed for years. Santa Cruz Wharf, for example, faced delays due to lawsuits over environmental impact reports, while interim repairs began too late to prevent further damage from extreme storms. Similarly, San Diego’s Ocean Beach Pier has been deemed irreparable, necessitating an $8 million replacement project. Many other piers, such as the Ventura Pier, have required substantial restoration following storm-induced damage, and some, like Seacliff State Beach Pier, have been removed entirely after severe deterioration.

California’s coastal piers are at a crossroads. Most were built over a century ago, originally designed for calmer seas and different purposes. While they now serve as cultural and recreational hubs, the question of their future looms large. With limited resources, officials must make tough decisions about which piers to protect and how to adapt to the changing climate. As Patrick Barnard of the U.S. Geological Survey notes, strategic prioritization will be key as the state grapples with the growing impacts of climate change on its historic coastal infrastructure.
