DGGS collected and processed lidar data and conducted landslide susceptibility mapping for this project using funds provided by the Federal Emergency Management Agency (FEMA) Cooperative Technical Partnership (CTP) Program grant number CTP EMS-2021-CA-00013-S01. We thank our reviewers Katreen Wikstrom Jones (DGGS) and Jacqueline Foss (U.S. Forest Service) for their thoughtful comments that helped improve the quality of this product. We also appreciate DOT&PF engineer Travis Eckhoff, P.E., for his local knowledge that helped verify our models, and Dr. Margaret Darrow (University of Alaska Fairbanks) for her insight into the Beach Road landslide. We also acknowledge Victoria Nelson for her countless hours spent performing soil laboratory testing and mapping landslide scarps in support of this project while working on her master's thesis.
The deadly Beach Road landslide that occurred on December 2, 2020, in Haines, Alaska, highlights the significant safety and financial risks posed by slope failures to people and infrastructure. To better inform the Haines Borough of their potential landslide hazards and increase the city's hazard resiliency, the Alaska Division of Geological & Geophysical Surveys (DGGS) developed maps of historical and prehistorical slope failures, shallow landslide susceptibility, and modeled debris flow runouts.
