Resilient Transportation Systems
WSDOT’s maintenance crews work hard to keep up with extreme storms and damage they cause. Understanding future climate threats is essential for a safe and sustainable transportation system.
WSDOT Climate Change Pilot Projects
WSDOT has completed two FHWA climate change pilot projects:
In the first pilot, WSDOT tested FHWA’s conceptual risk assessment model and successfully completed a statewide assessment of climate vulnerability of state-owned transportation assets. GIS layers showing the results of the statewide vulnerability assessment are available on the Community Planning Portal.
The second pilot project applied FHWA’s framework for adaptation planning and decision making. Our team created a process that will help transportation planners better connect information across sectors (in this case hydraulic data) and coordinate long-term solutions to extreme events.
NEPA/SEPA Guidance for project teams
WSDOT uses climate science and tools to estimate greenhouse gas emissions when planning and designing major projects.
Our work supports Results WSDOT’s Environmental Stewardship Goal to Improve environmental conditions; leave it better than before. WSDOT plans and those major capital projects will document how climate change and extreme weather vulnerability are considered, and propose ways to improve resilience.

WSDOT’s work is supported by state and federal policy directives.
Department of Ecology maintains up-to-date links to state climate change information resources.
Washington State is one of a handful of state’s that have completed state action plans tracked by Georgetown Climate Center see - Preparing for a Changing Climate: Washington State’s Integrated Climate Response Strategy
. The state’s action plan, “Preparing for a Changing Climate: Washington State’s Integrated Climate Change Response Strategy,” was prepared by Ecology in collaboration with the state departments of Agriculture, Commerce, Fish and Wildlife, Health, Natural Resources, and Transportation. The state agencies drew on the policy, management and scientific expertise of a broad range of stakeholders to develop the recommendations that are the basis of the report.
