The New Orleans Surge Barrier is a critical flood protection system designed to safeguard the city from storm surges, particularly during hurricanes. Constructed after the devastation of Hurricane Katrina in 2005, the barrier helps prevent water from the Gulf of Mexico from inundating low-lying areas of the city. This structure is part of a larger network of levees and floodwalls managed by the U.S. Army Corps of Engineers. It plays a vital role in enhancing the resilience of New Orleans, ensuring the safety of its residents and infrastructure against future flooding events.
