FHWA Case Study Highlights Tennessee DOT Climate Resilience Pilot

The Federal Highway Administration has released a case study on the extreme weather vulnerability assessment conducted by the Tennessee Department of Transportation (TDOT) under the FHWA’s Climate Resilience Program. TDOT partnered with Vanderbilt University to develop a statewide GIS-based inventory of the state’s critical transportation assets across various modes and identified historical and future extreme weather scenarios to determine where transportation assets are most vulnerable. The assessment serves as a screening process for more detailed study and provides input for developing TDOT’s risk-based transportation asset management plan.

FHWA Case Study Focuses on Michigan DOT Climate Resilience Pilot

The Federal Highway Administration has released a case study on the climate vulnerability assessment conducted by the Michigan Department of Transportation (MDOT) under the FHWA’s Climate Resilience Pilot Program. MDOT formed a Technical Advisory Committee and internal working group, composed of state agencies, academic institutions and various other stakeholders, that was tasked with integrating the assessment into MDOT’s decision-making process. The committee and working group gathered information concerning key climate stressors; conducted an assessment of transportation assets to precipitation and extreme heat; analyzed the consequences of removing an asset from service; and performed a risk analysis for five areas across the state. MDOT identified high-risk assets and determined that additional data on elevation, flood plains and land use are needed to create a robust assessment. For more information, link to the case study.
