Following Hurricane Katrina, the US Army Corps of Engineers is building a hurricane protection system with a 100-year level of protection. The focus of the project is to prevent the area around New Orleans from flooding. A long-term planning study running alongside this investigates other measures to prevent Southern Louisiana against flooding in the future. A component of this is to stop the surrounding wetlands from eroding, and to partly restore them in the Mississippi Delta, so that they can act as a buffer zone to protect the area in the future.

Royal Haskoning provides project management skills and state-of-the-art technical expertise on key topics, combined with new techniques and stimulating discussions to include resiliency at all levels to help the USACE to achieve its goal by 2011.

The USACE has been very pleased with Royal Haskoning's contribution so far: "Without Royal Haskoning we would never ever be where we are right now. Their expertise and enthusiasm are an enormous added value".
