Design Guide and Standards for Infrastructure Resilience

Extreme weather events such as hurricanes, droughts, heat waves, convective storms, floods, and wildfires have significant adverse impacts. Sea levels, temperatures, and precipitation patterns are expected to increase in frequency and severity and stress transportation systems, increasing the risk of disruptions, damage, and casualties. Infrastructure planning and design should account for these conditions to minimize impacts, yet this is not adequately addressed in current design standards and guidance. Translating climate projections and extreme weather data into information usable for project-level design and the development of design specifications is complex. Current design criteria for building and retrofitting transportation infrastructure are generally developed with an implicit assumption that the climate conditions will remain static over the design life. State and federal guidelines and requirements for producing transportation project designs for more resilient transportation assets have increased in recent years. Recognizing the benefits of incorporating resilience into all facets of the project life cycle, many transportation agencies are beginning to conduct engineering-informed adaptation studies and develop ways to formally integrate resilience into the project development process. A number of highly related, recent research projects have been initiated and/or completed by NCHRP and FHWA. Practitioners need additional assistance evaluating and balancing the potential costs and benefits of incorporating recommended guidance and standards that consider resilience to extreme weather and future climatic conditions in their project development processes. The objectives of this project are to (1) briefly summarize how extreme weather events, long-term climate changes, and climate resilience impact transportation project delivery, infrastructure life-cycles, and asset management practices; (2) identify current and projected future climate variables to be considered during the design of transportation projects to increase resilience; (3) develop recommendations for updating design processes that include consideration of extreme weather events and increase resilience to climate impacts; and (4) develop a project delivery climate change resilience design guide.
