Coastal natural infrastructure is exposed to sea level rise, wave action and inundation from increasing storm events . Beaches, in particular, are highly exposed to climate-induced coastal erosion . Research from settlements across coastal Southern California, USA, show that 67% of all beaches may completely erode by 2100 . Coastal zones across Cancún, Mexico, are exposed to a combination of sea level rise and tropical hurricanes, further exacerbated by urban development patterns blocking natural sediment replenishment to beaches . In another case, beach erosion along the heavily urbanised Valparaíso Bay, Chile, is heightened by El Niño Southern Oscillation  events, which in the past have caused an additional 15-20 cm in mean sea level rise .
