How America Built a $14.5B Storm Surge Barrier After Hurricane Katrina

How America Built a $14.5B Storm Surge Barrier After Hurricane Katrina In August 2005, Hurricane Katrina's storm surge broke through New Orleans' levees in over fifty places, flooding eighty percent of the city and killing more than 1,800 people. Investigators found the disaster wasn't just a storm — it was a preventable engineering failure. In response, the US Army Corps of Engineers built the largest civil works project in its history: a $14.5 billion system centered on the Inner Harbor Navigation Canal Lake Borgne Surge Barrier, a 1.8-mile wall nicknamed the "Great Wall of Louisiana," built on foundation piles driven over 100 feet into soft delta mud, with ship-sized sector gates and some of the most powerful drainage pump stations on Earth. This is the full story of how it was designed, built, and tested against a real hurricane — and the questions that remain about whether it's enough for what comes next. 📌 Disclaimer This video is created for educational and informational purposes only.
