An Introduction to Coastal Flood Safety in the United States

Coastal flooding poses significant risks to communities along the United States' shorelines, affecting millions of residents and causing substantial economic losses. Understanding the causes, risks, and safety measures associated with coastal flooding is essential for effective preparedness and response.

What Causes Coastal Flooding?

Coastal flooding occurs when seawater inundates normally dry coastal land, typically due to:

  • High Tides and Storm Surges: Elevated water levels from storms can push seawater onto land.
  • Sea-Level Rise: Long-term increases in sea levels make coastal areas more susceptible to flooding.
  • Extreme Weather Events: Hurricanes and heavy rainfall can lead to significant flooding.

How Does Coastal Flooding Impact the U.S.?

Coastal flooding affects approximately 8.6 million Americans, with over $1 trillion in property and structures within a few feet of current sea level. (19january2021snapshot.epa.gov)
