On May 21-22, 2013, AASHTO held a national symposium, Impacts of Extreme Weather Events on Transportation, in Washington, D.C. The symposium was sponsored by AASHTO’s Sustainable Transportation: Energy, Infrastructure, and Climate Solutions Technical Assistance Program, in coordination with the Center for Environmental Excellence by AASHTO and the Federal Highway Administration. The symposium provided an opportunity for DOT staff from a broad range of disciplines to convene and discuss the implications of extreme weather events on transportation.
The event covered state DOT case studies related to experiences with extreme weather events; an overview of trends and projections for extreme weather in the United States; costs of extreme weather events; and risk management strategies in design, operations and maintenance, and asset management, and emergency response.

Day 1 Presentations
Welcome and Introduction
Welcome
Bud Wright, Executive Director, AASHTO
Gloria Shepherd, Associate Administrator, FHWA Office of Planning, Environment & Realty
Session I: State DOT Experiences with Recent Extreme Weather Events
Facilitator: Karuna Pujara, Maryland DOT
This session will feature case studies highlighting the extreme weather experiences of state DOTs. Case studies will describe impacts to transportation, share lessons learned on system performance, and contribute best practices.

New Jersey DOT: Our Bout with Superstorm Sandy
Richard Shaw – New Jersey DOT
Flooding in the Midwest: A Minnesota Case Study
Andrea Hendrickson – Minnesota DOT
Impacts of “Snowmageddon” on Transportation
Terry Bellamy – District of Columbia DOT
Case Studies on Wildfires and Dust Storms

Session II: Extreme Weather Events – Trends, Projections, and Integrating Information into Decisions
Facilitator: Elisabeth Kolb – New York State DOT
This session will cover trends and projections for extreme weather events across the United States. It will also provide examples of how state DOTs have partnered with agencies such as NOAA in order to access needed information on extreme weather events. During discussions, participants will exchange ideas for integrating available information into transportation decision making.

Facilitator: Kevin Walsh – Massachusetts DOT
Inland floods
Facilitator: Michael Kennerly – Iowa DOT
Winter storms
Facilitator: Randy Van Portfliet – Michigan DOT
Heat waves, wildfires, and droughts
Facilitator: Kristen Keener Busby – Arizona DOT
Presentation of Needs Statements
Session III: Costs of Extreme Weather
Facilitator: Elisabeth Kolb – New York State DOT
This session will provide participants with examples of how state DOTs and other agencies have evaluated the costs of extreme weather and benefits of adaptation.
Analyzing Extreme Weather Costs for Roadway Investment Decisions
Nathaniel Coley – U.S. DOT
Evaluating the Cost of Replacing Bonner Bridge
Joe Turner – North Carolina DOT
Discussion: Costs of Extreme Weather
What kinds of cost information do state DOTs need? How do state DOTs envision using
these cost data? What are the barriers to collecting this information? What could be done to help DOTs overcome these barriers?
Day 2 Presentations
Welcome and Day 1 Recap
Jennifer Brickett – AASHTO
Session IV: Managing Extreme Weather Events (Design, Operations and Maintenance)
Facilitators: Rick Land, Caltrans (Design) and Jennifer Brandenburg, NCDOT (Operations and Maintenance)
