The hurricanes Katrina and Rita caused massive damage in 2005 in parts of the states of Alabama, Texas, Mississippi and Louisiana. In New Orleans the levees failed, resulting in a considerable portion of the city being flooded. The US Army Corps of Engineers is working on repairing and improving the levees and has sought help in the Netherlands.

ARCADIS acquired a major Indefinite Delivery Indefinite Quantity (IDIQ) contract for design services, multidisciplinary advice and construction supervision for the protection of the New Orleans area against floods. The efforts of ARCADIS are focused on protecting the coast of the Gulf of Mexico against the effects of hurricanes in the future.
