Physical Infrastructure: Preliminary Observations on Options for Improving Climate Resilience of Transportation Infrastructure, Statement of Elizabeth Repko, Acting Director, Physical Infrastructure, Testimony Before the Subcommittee on Transportation, Housing and Urban Development, and Related Agencies, Committee on Appropriations, U.S. Senate [open pdf - 995KB]
From the Highlights: "Since 2013, GAO [Government Accountability Office] has included 'Limiting the Federal Government's Fiscal Exposure by Better Managing Climate Change Risks' in its High Risk List. In addition, according to the U.S. Global Change Research Program, a changing climate threatens the performance of the U.S. transportation system across all modes, including roads. Congress authorized approximately $43 billion of fiscal year 2021 formula funding for the U.S. Department of Transportation's FHWA [Federal Highway Administration]'s federal-aid highway program, which primarily funds highway planning and construction. This testimony discusses (1) GAO's framework for identifying opportunities to enhance the climate resilience of transportation infrastructure; and (2) preliminary observations on actions taken and options to further enhance the climate resilience of federally funded roads."
