  1. Extreme Weather Research and Tools Update Date: May 29, 2014 Committee: Standing Committee on Highways Presenters: Michael D. Meyer, Parsons Brinckerhoff

  2. AASHTO Extreme Weather Events Symposium • It pays to be ready and pre-plan • Practice, practice, practice • Know what is out there • Use all forms of communication media Best Practices for Extreme Weather Management

  3. AASHTO’s Center for Environmental Excellence Initiative SOM SCOE NASTO WASHTO SASHTO Update on Federal Programs and Recent Research SCOH SCOM STEICS SOD SOC

  4. STUDIES & RESEARCH ON EXTREME WEATHER & THE TRANSPORTATION SYSTEM NCHRP 750, VOL. 2

  5. KEY QUESTIONS • How Could Changes in Temperature Affect Road Assets? • How Could Changes in Precipitation Affect Road Assets? • How Could Sea-Level Rise Affect Road Assets? • How Could Greater Hurricane Intensity Affect Road Assets? • How Could Stressors Affect Ecological Systems? • What Are the Types of Adaptation Strategies that Can Be Considered by Transportation Agencies?

  6. For example…

  7. Bridge Culvert Pavement Slope or Wall Stormwater Infrastructure

  8. Slope or Wall Check All Precipitation More extreme rainfall events -Erosion and mass wasting -Floodplain extent and elevation Higher average precipitation -Increased vegetation growth -Direct effects Greater snowfall depths -Snow melt amounts Temperature Water level/Chemistry Wind

  9. Precipitation More extreme rainfall events -Erosion and mass wasting -Floodplain extent and elevation

  10. Use of enhancement of stormwater conveyance away from slope face
