  1. So what were the effects from wind? • Some structural damage, mostly to overhangs and roofs • Not much evidence of wind borne debris penetrating the building envelope • Lots of damage to building envelopes – roof, siding, soffits particularly

  2. South LA…success Wind damage: primarily building envelope

  3. Pass Christian, MS (new home)…survivor

  4. New Orleans –light damage toglazing, butto manybuildings

  5. Ocean Springs, MS…light damage

  6. Gulfport bank building…moderate damage

  7. Gulfport, MS…moderate damage

  8. Long Beach, MS…severe damage

  9. Gulfport (PEMB)…severe damage

  10. LA (support column failed…partial destruction)

  11. Slidell, LA…total destruction

  12. ASCE Levee Study Map Overtopping occurred first

  13. Water overtopping levee

  14. Levee Flooding – London Ave Canal

  15. Levee design issues – breached or overtopped?

  16. Floodwall failure

  17. Damage behind the levees

  18. “Post-Flood Actions Affect Mold Growth” New Orleans House opened and aired out quickly with low mold growth House closed and not aired out quickly with extensive mold growth

  19. What can we do? • Build higher, stronger, safer • Adopt strong building codes • Provide sound recovery information like new flood maps and reconstruction guidance • Critical facilities must be better built • Educate – citizens must accept some level of risk if they want to live in a hazardous area (which a hurricane region is)

  20. We’ve got to build them better ….

  21. D’Iberville, MS

  22. Biloxi, MS

  23. Long Beach, MS

  24. Performance Standards for Wind • No structural failure • Load paths remain connected through to the foundation • Minor building envelope covering loss • Building access is easily repaired • Able to re-occupy the building immediately after utilities are restored • Critical facilities can be occupied safely during event

  25. Performance Standards for Flood • Flood damage can be cleaned up • After drying out, building can be re-occupied • Repairs might consist of drywall, insulation and wood trim replacement • Structure is still standing on it’s own foundation

  26. Post-Katrina • LA adopted state-wide building code (IBC) • Several MS communities previously without codes have adopted IBC/IRC • Several communities have either adopted flood recovery maps or added freeboard (additional height) so rebuilding can begin • Lots of confusion about how to regulate all the changes in building standards (use of IBC/ASCE 7) • Land values escalating rapidly
