Hawaii Beach Access Threatened

- Hawaii's sea level has been rising at an accelerated rate, with projections showing an increase of about 8 inches by 2050. This rise in sea level exacerbates coastal erosion, threatening 70% of the state's beaches and thousands of structures. - The economic stakes of beach disappearance are substantial; a complete loss of Waikiki Beach, for instance, could result in a nearly $2 billion annual loss in visitor spending. - On Oahu, nearly 30% of the sandy shoreline is already hardened by structures like seawalls. Projections indicate that by mid-century, up to 40% of the island's sandy beaches could be lost if shoreline hardening continues. - The debate over seawalls is not new; as early as 1927, an Engineering Association of Hawaii report identified seawalls as the primary cause of erosion in Waikiki. - In 2020, Hawaii passed Act 16, a landmark law that prohibited the construction of new private shoreline hardening structures on sandy beaches to protect public access and preserve the natural coastline. The current legislative proposals are seen by some as a potential weakening of this law. - Alternatives to seawalls, often referred to as "soft" approaches, are being explored and implemented. These include nature-based solutions like dune restoration, which has been used on Oahu's North Shore to protect homes while preserving the beach. - The current legislative proposals, House Bills 1846 and 2205, would not completely ban seawalls but would allow for "limited, carefully conditioned shoreline protection measures" and establish "regional shoreline mitigation districts" to streamline permitting. Both bills were deferred in committee in February 2026 for further revision. - Property owners in areas with severe erosion, such as Kahana on Maui, have been dealing with shrinking shorelines for over a decade and are advocating for the proposed bills to provide more immediate solutions to protect their properties.
