Hurricane & Storm Damage Risk Reduction System

[2] The Greater New Orleans HSDRRS is engineered to the 100-year level of risk reduction against tropical events and related rainfall and storm surges.

The $14 billion system includes the construction or improvement of 133 miles of perimeter risk reduction features, such as levees, floodwalls, floodgates and pump stations.

Construction of the system also included resiliency features, such as the armoring of the backside of levees and floodwalls to prevent scour in the event of wave overtopping.

[3] The Corps also supports the multiple lines of defense strategy for reducing risk, which includes the restoration of Louisiana's coastal areas.

Dutch experts of engineering firms such as Arcadis, Royal Haskoning/DHV, Fugro and HKV Consultants were closely involved in the planning, designing and implementation.
