Coastal Storms

Coastal storms can bring flooding, storm surge, and the potential for severe damage. In addition to people living and working in vulnerable areas, critical systems can be impacted, such as stormwater infrastructure, emergency facilities, and roadways.

These Digital Coast resources help officials understand potential impacts and take the steps needed to lessen damages and increase community resilience.
