Opinion: Post-Ida failures show why we need to adapt

In the 16 years since Hurricane Katrina, Louisiana and the federal government have engaged in a massive experiment called "disaster resilience," the idea that physical and community infrastructure are integrated and built to recover and maintain operations in the face of extreme events. Yes, thankfully, the single-purpose, cost-effective flood levees that the US Army Corps of Engineers built after Hurricane Katrina worked.
