Millions are being spent on Hawaii's eroding coastal properties as owners fight to save their investments.

The collision between private property rights and the public's right to access beaches highlights the complex socio-economic fallout of climate change. As sea levels rise, the very land that supports these estates is washing away, leading to legal battles over what remains accessible to the public.

Homeowners are spending heavily on coastal defenses like seawalls, but these structures often exacerbate erosion elsewhere along the shoreline.

The long-term vulnerability of Hawaii's coastlines means that even with significant investment, many properties will eventually be lost to the sea.

Can local infrastructure withstand future compounding shocks?

With rising seas and increased storm activity, the structural integrity of coastal defenses is questionable. The economic viability of these areas could diminish as insurance becomes unaffordable or unavailable. Public access to beaches may become more restricted due to private property claims.

The outlook for local infrastructure in Hawaii's coastal regions is negative.
