Through a process of stakeholder meetings, review of previous reports, and extensive correspondence with communities,178 Alaska communities were found to have reported erosion problems. After subsequent investigation, the Corps designated 31 communities as “Imminently Threatened”—indicating that they should be considered for immediate action by either initiating an evaluation of potential solutions or continuing with ongoing efforts to manage erosion. 19 of those 31 communities are located along the coastline of western Arctic Alaska.

Groups like the State of Alaska, Department of Community, Commerce and Economic Development rely on this initial inventory to direct resources to respond to erosion hazards. While this listing is a helpful start, there are likely many other communities facing significant climate change challenges.
