The cost of sea defences can vary widely depending on factors such as the type of defence, the location, and the scale of the project. Costs can range from thousands to millions of dollars for smaller projects like beach nourishment or seawalls, to billions of dollars for larger projects like barrier islands or storm surge barriers.
