The U.S. Army Corps of Engineers recently awarded a $614.8 million project to build three permanent canal closure and pump stations in New Orleans. They will replace temporary structures built in 2006 at the mouths of three drainage canals connecting to Lake Pontchartrain.
The stations are designed to block surges from the lake caused by a "100-year storm," a strong hurricane that has a 1% chance of occurring in any year.
