Alaska Coastal Flooding

By 2050, Alaska's 100-year coastal floodplain is projected to expand by more than 15,000 square miles, by far the most land of any state. Coastal flooding could disproportionately affect Native Alaskans, who make up the majority of residents in Alaska’s remote coastal villages along the western and northern coasts where topography is relatively flat.

Is Alaska taking action?

  • Alaska has taken a lot of action to address its current coastal flooding risks through its Hazard Mitigation Plan, the Alaska Community Coastal Protection Project, transportation resilience programs, and energy and public health emergency preparedness programs
  • The state is working to understand its vulnerability to future changes in sea levels and develop climate change adaptation measures but very little action has been taken to implement these measures beyond some community and transportation efforts
