Climate Resilience: Options to Enhance the Resilience of Federally Funded Roads and Reduce Fiscal Exposure, Report to Congressional Requesters   [open pdf - 6MB]

From the Highlights: "Changes in the climate pose a risk to the safety and reliability of the U.S. transportation system, according to the 2018 'Fourth National Climate Assessment'. Congress authorized about $45 billion per year in federal funding for roads through 2021 and appropriated about $900 million per year in disaster assistance for fiscal years 2016 through 2020. In 2013, GAO [Government Accountability Office] included 'Limiting the Federal Government's Fiscal Exposure by Better Managing Climate Change Risks' on its High-Risk List. Enhancing climate resilience--acting to reduce potential losses by planning for climate hazards such as extreme rainfall--can help manage climate risks. GAO was asked to review climate resilience efforts for federally funded roads. This report examines (1) FHWA [Federal Highway Administration]'s climate resilience efforts and (2) options to further enhance them. GAO reviewed FHWA documents and a non-generalizable sample of projects that used FHWA's climate resilience resources, analyzed the content of 53 reports and pieces of legislation to identify options, interviewed stakeholders and agency officials, and analyzed options and FHWA efforts using GAO's October 2019 'Disaster Resilience Framework'."
