Coastal Surge Flooding is a risk for all coastal communities.
39% of the U.S. population lives in counties that are directly adjacent to the open ocean, Great Lakes, or major estuary.
Coastal flooding is caused by storms in the form of storm surge pushed ashore by hurricanes or other storm systems. Additionally, coastal flooding can also be caused by rainfall raising tide levels in the form of nuisance flooding, also known as high tide flooding.
The way to protect from coastal flooding damages is to elevate coastal homes and businesses, have adequate insurance, and not build in coastal areas that are prone to flooding. Some natural and humanmade methods can be used to mitigate, as well. These methods include levees, wetland and marsh restoration, flood water management infrastructure, living shorelines, and green infrastructure.
