1 Executive Summary Storms, floods, droughts, and other natural hazards are combining with sea level rise, new temperature and precipitation norms, and other effects from climate change to increase the vulnerability of the nation's transportation systems. The United States experienced a record-breaking 22 billion-dollar natural disasters in 2020.

2 INVESTING IN TRANSPORTATION RESILIENCE This report reviews current practices by transportation agencies for evaluating resilience and conducting investment analysis for the purpose of restoring and adding resilience. These practices require methods for measuring the resilience of the existing transportation system and for evaluating and prioritizing options to improve resilience by strengthening, adding redundancy to, and relocating vulnerable assets.

4 INVESTING IN TRANSPORTATION RESILIENCE are likely to continue to struggle with the translation of resilience from a concept to a decision criterion. While this report could not identify a single metric, or even a small set of metrics, that can be readily developed and generally applied to ease this struggle, it does outline a systematic framework for making resilience a key part of the investment calculus.

EXECUTIVE SUMMARY 5 future losses, in relation to the life-cycle costs of doing so should be promoted as the basis for selecting investments in resilience. Although the practice of BCA is often associated with an over emphasis on the benefits and costs that can be more confidently monetized, the nature of resilience impacts, coupled with the demands of practical decision making, call for analyses that are attentive to all important effects, whether represented in monetary, quantitative, or qualitative terms.

6 INVESTING IN TRANSPORTATION RESILIENCE RECOMMENDATION 5: The Office of the Secretary of Transportation should coordinate with the modal agencies on the design and conduct of structured pilots to assess and demonstrate the applicability of each agency's guidance and suggested tools for estimating resilience benefits according to the recommended multi-step analytic framework. FHWA's series of pilot programs for highway resilience analysis should be used as a model for these structured mode-specific pilots, which have led to increased state and local transportation agency familiarity with resilience analysis and to continual improvements in FHWA's guidance on analytic methods and appropriate tools.
