The levees that protect New Orleans are sinking, just as officials knew they would. The Army Corps is doing a study to figure out what repairs are needed. On Tuesday the agency held several public meetings on the process.
The Corps and local levee authorities built a $14 billion Hurricane and Storm Damage Risk Reduction System (HSDRRS) around the city after Hurricane Katrina. Because of the soft soil the levees were built on, they’re naturally sinking. Sea level rise also poses a risk.
