consideration for minimizing cost while preserving or improving the condition.” This handbook examines the use of pavement and bridge management systems to perform LCP analysis in support of risk-based TAMPs. Several aspects of TAMPs and transportation performance management, such as performance model development, target setting, and performance gap analysis, provide input to LCP and are impacted by LCP results. » Nature-Based Solutions for Coastal Highway Resilience: An Implementation Guide. August 2019. Report FHWA-HEP-19-042. Accessed July 27, 2020 from: https://www.fhwa.dot.gov/environment/sustainability/resilience/ongoing_and_current_research/green_in frastructure/implementation_guide/ This Implementation Guide helps practitioners understand how and where nature-based and hybrid solutions can be used to improve the resilience of coastal roads and bridges. It summarizes the potential flood-reduction benefits and co-benefits of these strategies. The guide follows the steps in the project delivery process, providing guidance on how to consider nature-based solutions in the planning process, how to conduct a site assessment to determine whether nature-based solutions are appropriate, key engineering and ecological design considerations, permitting approaches, construction considerations, and monitoring and maintenance strategies. The guide also includes appendices with site characterization tools, decision support for selecting nature-based solutions, suggested performance metrics, and links to additional tools and resources. Note: the FHWA website on nature-based solutions also includes results of pilot projects.

Accessed July 27, 2020 from: https://www.fhwa.dot.gov/asset/resources/pilot.pdf This FHWA pilot program illustrates how state DOTs can incorporate information on resilience into asset management programs and their TAMPs, including assessment of risks and LCP. Five of the six pilots participating in the pilot program examined the vulnerability of highways to extreme weather events.

It relates the asset management plan to performance measures and state DOT performance and condition targets. It also adopts a life-cycle costing perspective on considering asset risks. A process for developing the asset management plan includes the identification of risks and the use of a prioritization process for selecting those assets in most need of risk mitigation.
