Geohazards—such as landslides, liquefaction, rockfalls, subsidence, expansive/collapsible soils, and erosion—can pose major threats to transportation assets. Extreme weather events can also trigger and/or exacerbate geohazards, and the increasing incidence of such events is a concern in certain regions of the United States. A geohazards management program that evaluates the associated risk can help transportation agencies manage these threats by making comprehensive system performance decisions. Such a program can help agencies manage cost-effective methods for characterizing and reducing risk, develop adaptation methods, and establish a resilient transportation system.

A Peer Exchange was held March 22–23, 2016, in Atlanta, Georgia, to gather experts from different fields relating to geologic hazards, climate change, extreme weather events, and geotechnical asset management (GAM). The purpose was to share perspectives and brainstorm ideas on how FHWA can best continue its geologic hazards program and research. Feedback from the Peer Exchange contributed to updating a draft work plan from Phase I of this study on geohazards, extreme weather events and climate change resilience. The Peer Exchange consisted of presentations from attendees, discussion based on these presentations, breakout sessions for more focused discussion, and brainstorming about suggested changes to the provided draft work plan for a future Phase III study on geologic hazards, extreme events, and climate change. This report provides a summary of the Peer Exchange meeting.
