Strengthen Kauaʻi County Setback Rules

A shoreline setback determines the minimum distance inland a structure must be built from the shoreline. It is one of the most important tools the county has to protect public trust resources as coastlines shift over time.

For years, a major gap in Kauaʻi’s shoreline setback rules allowed structures in high-risk coastal areas to be rebuilt under the guise of “repairs,” bypassing updated setback requirements. Bill 2984 addresses this issue by requiring cost breakdowns and post-construction verification to ensure that projects categorized as repairs are not effectively substantial rebuilds.

The bill also strengthens how setbacks are applied by increasing baseline setback distances, adding a 20-foot buffer to account for sea level rise and storm impacts, and more consistently tying setback calculations to certified shoreline data. It further requires a certified shoreline survey for larger repair projects and ensures that development decisions are based on an accurate, officially determined shoreline.

Importantly, the bill recognizes that shoreline erosion is not a private issue and has widespread effects on public trust resources and access. The inclusion of a 30-day public comment period improves transparency and ensures that impacted community members have the opportunity to provide input.

Most significantly, Bill 2984 requires property owners to agree to retreat, relocate, or remove structures threatened by coastal erosion as a condition of approving new structures or substantial improvements. This forward-looking provision supports a more proactive approach to managing long-term coastal risk.

The Kauaʻi Chapter advocated in strong support of this bill. We deeply grateful that the Kauaʻi County Council and Planning commission recognized the importance of strengthening setback standards, improving transparency, and planning for inevitable shoreline change. Bill 2984 represents a meaningful step forward in protecting Kauaʻi’s public trust resources and advancing more resilient coastal management.
