  2. Extreme Weather Events Affecting Alabama

  3. Hurricanes 2005 Season Arlene Cindy Dennis Katrina Rita Affected ALDOT in one form or another

  4. Tornados

  5. Significant Wet and Dry Cycles 2007 2009

  6. Significant Wet and Dry Cycles Average Annual Rainfall 2009 Rainfall

  7. Snow and Ice • Small events compared to many other states • Huge impact within the state • Tend to be icy events

  8. Impact of Extreme Weather Events on ALDOT O&M

  9. impacts to ALDOT O&M • Pace of events has increased • Severity of events has increased • Public expectations have increased greatly • Particularly the degree of government response that is expected • Costs associated with events have risen • Impact of recovery costs on maintenance budgets continues to increase • Impact of recovery effort on ability to perform regular operations has increased • Especially dueto compliance with debris removal requirements • Has forced Region, Division and District personnel to gain experience and develop expertise in administering recovery efforts • Impacted infrastructure directly impacts ALDOT O&M

  10. Roadway Failures Hurricane Ivan

  11. Sinkholes I-65 in Morgan County Large traffic management requirement (all NB interstate traffic on detour)

  13. Slope Failures (small) Mobile County

  14. Slope Failures (large) RussellCounty

  15. Slope Failures (even larger repair) RussellCounty

  16. ADJUSTMENTS TO o&m Due To Extreme Weather

  17. Changes to ALDOT O&M • Emergency Management has become a full time job • Was an additional duty for many years • Now assigned to a full time staff member • Assistant Bureau Chief level – same as other maintenance functional areas • Improved and strengthened relationship with State Emergency Management Agency • Greatly increased need for recurring training in Region/Divisions and Districts • Focus on specific “smaller” solutions • Portable Highway Advisory Radios (HARs) • Coordination across and between Divisions • Less specialized equipment

  18. O&M Lessons Learned

  19. “Design” versus “Response” • Designing a transportation system to cover all extreme events at every location where a failuremay occur falls between: • Impractical and wildly expensive • Impossible • “Design vs. Response” decision is risk-based • Quantitative, formal process is sensitive to assumptions. • Qualitative, informal process is influenced by past response performance. • Alabamaperformed formal risk-based analysis with TSA. Only one asset in the entire state was identified as a candidate for design-based mitigation of risk. • DOTs tend to perform well in response-mode • Make use of that capability

  21. ALDOT O&M Best Practices

  22. ALDOT O&M Best Practices • Improved Program Management of Recovery Efforts • ER • FEMA • ALDOT Internal processes for managing events and post-event audits • Full time Assistant Bureau Chief over Emergency Management • Increased focus on continuance of operations • Refined philosophy regarding response to an event versus designing for an event • Revised practices for removing trees from ROW • Use of expedited procurement practices (Code of Alabama) • Does not require Governor to issue a State of Emergency (SOE)

  23. ALDOT O&M Best Practices • Dissemination of Road Condition information • Everyday events • Large scale events (call center) • Improved systems and practices for moving OS/OW traffic before, during and after an event • Reduced need for waivers and proclamations • Better communication within ALDOT during an event • Video Conferences • Phone bridges • Use of portable video surveillance equipment (EarthCam)

  24. Developed Contra-flow Plan Not as helpful as first expected Very difficult to execute – must exercise Prepare to use it … but work like crazy to avoid it
