Reinforced Turf Mat Grass to Armor Hurricane Levees
The Army Corps of Engineers plans to spend about $300 million to armor about 80 miles of earthen levees in New Orleans, Louisiana, with a combination of reinforced mats and Bermuda grass. This covering will protect them from potential erosion caused by overtopping.
This is a key item pending in the upgrade of the region’s hurricane system, launched after Hurricane Katrina. The armoring aims to prevent the massive erosion of earthen levees which contributed to catastrophic flooding during the 2005 storm.
The Corps said it will need nearly 1.5 square miles of sod, enough to cover 703 NFL football fields. Multiple contracts will be required to cover the 80 miles of levee.
This project represents the last major construction project to begin in the $14.6 billion post-Katrina levee reconstruction program.
