1. Do nothing. This is cheap in theory but may have hidden costs due to having to deal with the impacts of erosion.
2. Retreat and relocate. This involves moving infrastructure and property back away from the area of risk and allowing the coast to do its thing in a more natural manner. There are big challenges with how you do this and manage people who own beachfront property.
