Coastal Hazards

Hurricanes in the Bahamas do not happen as often, but when they do it causes significant amount of damage. In hopes of preventing this damage, officials have constructed sea walls in hopes of preventing huge damage on the roads due to roads being too close to the shorelines. The Bahamas shoreline erosion is due to number of factors which may include offshore dredging, stealing sand from beaches and sand dunes, construction on the beach or immediately offshore, or vegetation removal. 

As far as residents knowing about this, they hold meetings that discuss the exhibits of how they want to make sure they are away. However, building these sea  walls takes sufficient time and effort. Sometimes the walls may collapse due to poor structure or environmental abuse such as heavy waves, walls collapsing, and wall end failure. As we would assume for quality sea walls it is more on the pricer side than affordable depending on the island's economic status and views regarding building stable sea walls.
