HW17A100/WH707 ; Since 2014, the Federal Highway Administration (FHWA) and Rijkswaterstaat, the government agency responsible for transportation and water infrastructure in the Netherlands, have been collaborating on the topic of infrastructure resilience. From 2016 through 2018, the agencies conducted an applied comparison of a suite of resilience tools developed and/or used by the respective agencies: the FHWA Vulnerability Assessment and Adaptation Framework, and Roads Today, Adapted for Tomorrow (ROADAPT). From 2019 to 2021, FHWA and Rijkswaterstaat - along with Washington State Department of Transportation (WSDOT) and North Carolina Department of Transportation (NCDOT) - participated in a collaboration to explore nature-based solutions that reduce flood hazards to highways and provide environmental benefits. Through monthly conference calls and occasional topic-specific webinars, the partners discussed resources and strategies for nature-based resilience and specific transportation projects that incorporated nature-based strategies. The partners shared lessons learned that could be relevant for transportation projects under consideration by the other agencies. They also shared information on climate resilience strategies more broadly.
