The Federal Emergency Management Agency (FEMA) provided funding through a Cooperative Agreement to the Alaska Division of Geological & Geophysical Surveys to complete this Coastal Bluff Stability Project under grant number EMS-2019-CA-00022-R05. We thank FEMA Cooperating Technical Partners Program, the City of Homer, and the Homer Planning Commission for supporting this work. Major improvements were made thanks to the thorough and insightful reviews by Bret Hig Higman, Chris Maio, Barrett Salisbury, and FEMA. Much of this study was possible thanks to the foundational work by Steve Baird and the Kachemak Bay National Estuarian Research Reserve.
These coastal hazard assessment products can guide decisions to reduce risk.
