Hurricane Katrina Storm Damage Risk Reduction
New Orleans , LA , United States
At a Glance: $14 billion risk reduction program in New Orleans and Southern Louisiana after Hurricane Katrina. Program includes levees and floodwalls, locks, dams and sector gates, pump stations, freshwater diversions, marsh creation, and barrier island restoration.
The challenges this project addresses are: Flooding, Coastal & Tidal Flooding, Hurricanes & Severe Storms, Sea Level Rise, Education, Basic Services, Water Quality, CO₂ Reduction, Buildings, Energy Efficiency
Hurricane Katrina resulted in unprecedented damage to the Gulf Coast. There was, and continues to be, a need to protect the Gulf Coast from ongoing flood and hurricane risk.
USACE used Atkins design & engineering services to address this/these challenge(s).
Atkins worked with USACE to develop and manage the $14 billion risk reduction program in New Orleans and Southern Louisiana, which includes levees and floodwalls, locks, dams and sector gates, pump stations, freshwater diversions, marsh creation, and barrier island restoration. HSDRRS was designed for a 50-year project life and the design accounted for sea level rise, subsidence and increased storm frequency throughout that time frame. 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.

- Construction of dozens of resilience projects, including levees, floodwalls, marsh creation and barrier island restoration
- Construction of several of the United States' first large-scale green infrastructure projects
Local Government Champion: U.S. Army Corps of Engineers (USACE) - not local government
Something Unique: Resulted in the construction of some of the U.S.'s first large-scale green infrastructure projects for hurricane risk-reduction
Who should consider? Coastal communities recovering from hurricane damage; coastal communities seeking to reduce hurricane risk
