The more resilient an organization is, the more able it is to successfully deal With disturbances and volatility.
    • Case  Study   •  Greater  New  Orleans  post-­‐Katrina  Infrastructure   and  Coastal  Restora?on  System   – Biggest  Untold  Story  of  Success  and  Possibility!   – Massive  undertaking  can  serve  as  example  for  Climate   Change  Adapta?on  Measures  to  reduce  actual  risk— not  just  insure  financial  exposures   – Started  in  2007,  func?onal  in  2011  –AMAZING!!   – U?lized  Expedited  NEPA   – During  Hurricane  Isaac  in  2012  avoided  damages  far   greater  than  its  cost  –  an  excellent  ROI
