Abstract: I served as a geotechnical expert for the U.S. Department of Justice (DOJ) supporting the defense of the U.S. Army Corps of Engineers (USACE) against alleged professional negligence in its design of the flood walls for the Inner Harbor Navigation Canal (IHNC). A group of attorneys representing individuals affected by the levee failures launched a lawsuit, as Plaintiffs, seeking tens of billions of dollars of restitution from the U.S. government. This article briefly describes the case and its outcome, focusing on the different theories of failure for two flood wall breaches and presenting my assessment of the failures based on additional investigations.
