Coastal Flood Safety Guide: Protecting Yourself and Your Community

Coastal flooding poses significant risks to communities along the United States' shorelines. Understanding its causes, recognizing the associated dangers, and implementing effective safety measures are crucial steps in safeguarding lives and property.

What Causes Coastal Flooding?

Coastal flooding results from various factors, often occurring simultaneously, leading to more severe impacts:

  • High-Tide Flooding: Occurs during extreme high tides, known as king tides, which happen a few times per year when the sun, moon, and Earth align. (coast.noaa.gov)

  • Storm Surge: Generated by severe storms like hurricanes and nor’easters, strong winds push water onshore, raising sea levels significantly. (coast.noaa.gov)

  • Sea Level Rise: Long-term increases in sea levels contribute to more frequent and prolonged flooding events. (coast.noaa.gov)

  • Tsunamis: Large waves caused by underwater disturbances, such as earthquakes or landslides, can inundate coastal areas. (prod-01-alb-www-noaa.woc.noaa.gov)

Recognizing the Dangers of Coastal Flooding

Coastal flooding can lead to:

  • Property Damage: Floodwaters can erode foundations, damage structures, and destroy personal belongings.

  • Infrastructure Disruption: Flooding can damage roads, bridges, and utilities, leading to long-term service interruptions.

  • Environmental Impact: Saltwater intrusion can harm freshwater resources, and flooding can lead to the spread of pollutants.

  • Health Risks: Floodwaters may contain contaminants, posing health hazards to those exposed.

How to Prepare for Coastal Flooding

Effective preparation involves:

  • Stay Informed: Monitor local weather forecasts and heed warnings from authorities.

  • Develop an Emergency Plan: Establish evacuation routes and communication strategies for your family.

  • Elevate Structures: Raise homes and critical utilities above potential flood levels.

  • Install Barriers: Use floodwalls or levees to protect properties.

  • Maintain Insurance: Ensure you have flood insurance to cover potential damages.

What to Do During a Coastal Flood

If flooding occurs:

  • Follow Evacuation Orders: Leave immediately if instructed by authorities.

  • Avoid Floodwaters: Stay away from moving water, as it can be deeper and faster than it appears.

  • Stay Informed: Keep updated with information from local officials and weather services.

How to Recover After a Coastal Flood

Post-flood recovery includes:

  • Ensure Safety: Wait for official clearance before returning home.

  • Document Damage: Take photos for insurance claims.

  • Clean and Disinfect: Remove contaminated materials and clean thoroughly to prevent health issues.

  • Seek Assistance: Utilize community resources and support services for recovery.
