Governor John Bel Edwards joined the Louisiana Coastal Protection and Restoration Authority (CPRA), the U.S. Army Corps of Engineers, and other state, local, and federal officials to celebrate the completion of the Hurricane and Storm Damage Risk Reduction System (HSDRRS) that will defend the Greater New Orleans area against severe storms.

Following Hurricane Katrina, Congress provided $14.5 billion which included construction of a system that will provide the Greater New Orleans area with a system that will defend against a storm surge that had a 1-percent chance of occurring in any given year as well as be resilient to larger storms.

The full up-front funding allowed USACE to apply the most current and up-to-date science and engineering during design and construction. Upon completion of construction, the federal government has fully turned the completed system over to Louisiana’s Coastal Protection and Restoration Authority for operation and maintenance.

According to the Governor's Office, the system had been constructed to the elevations necessary to provide the 1-percent storm surge level of risk reduction by 2011. Since then, USACE and its partners focused on building sustainable features, such as the three Permanent Canal Closures and Pumps, and incorporating resiliency against larger storms through features like armoring. Armoring prevents erosion and scouring that could threaten the structural integrity of the system in the event of an overtopping.

Structural approaches such as the HSDRRS are only one component of the overall hurricane preparedness plan. Equally important are the local, state and federal emergency response plans that are rehearsed and coordinated throughout the year.

As the region enters the 2022 Atlantic Hurricane Season, the HSDRRS should never be considered a life safety system. Although the system is designed to be resilient to storms larger than its design, the system cannot eliminate risk for those that live and work behind the system. Residents have an important role in further buying down this risk. Just as the federal, state and local emergency teams practice, train and collaborate so that they are ready and prepared to implement their plans, residents should develop and practice their own emergency preparedness plan. This personal plan must include staying closely informed during an event and being fully prepared to evacuate if the order is directed.
