Hurricane preparedness in New Orleans has been an issue since the city's early settlement because of its location.
New Orleans was built on a marsh. Unlike the first two centuries of its existence, today a little under half of the modern city sits below sea level. The city is surrounded by the Mississippi River, Lake Pontchartrain to the north, and Lake Borgne on the east.
The earliest-settled parts of New Orleans and surrounding communities are above sea level. However, flooding was long a threat, from the periodic high waters of the Mississippi and from more occasional severe tropical storms which pushed the waters of Lake Pontchartrain into settled areas. Construction of the levees along the River began soon after the city was founded, and more extensive river levees were built as the city grew. These earthen barriers were erected to prevent damage caused by seasonal Mississippi River flooding. The Lake Pontchartrain shore was mostly undeveloped swamp, and only small levees were built there in the 19th century.

Awareness of the city's vulnerability to hurricanes dates back to the early Colonial era. A major hurricane hit the city in September 1722, leveling many of the buildings in the young city.
1794 was perhaps as dreadful a year as the city of New Orleans ever experienced, as it suffered two hurricanes in addition to a major fire.
19th century hurricanes

The 19th century saw such hurricanes as the
The 19th century hurricanes were not nearly as media-covered, but they were still just as devastating as hurricanes are today. In this era, the news was not advanced enough to give minute by minute storm coverage. The 1856 Last Island Hurricane was the first major hurricane in the Atlantic hurricane season. Media coverage and storm identification were not at the stage to update the citizens of the area, so New Orleans and Last Island got completely decimated, and in turn got hit rather unexpectedly. Last Island ended up as a group of fragmented islands rather than a single one-completely destroying homes and families. The Chenière Caminada Hurricane of October 1893 also had a lasting impact whose wreckage was hard to prepare for. This natural disaster destroyed the island known as Chenière Caminada and about half the inhabitants were killed because of this disaster. Both of these islands were some of the earliest known islands in Louisiana.
Early 20th century hurricanes
1909 saw the Grand Isle hurricane hit the city. There was major flooding in the "back of town" area and in the undeveloped swamps north of town.
The 1915 New Orleans hurricane, or as it was called locally, "the Great Storm of 1915" struck with more wind damage than the 1909 storm. Flooding was more limited in scope and duration due to improved drainage pumping. However, Lake Pontchartrain rose to a higher level than previously recorded, overtopping some of the back levees. The Sewage and Water Board recommended taller levees to protect the city from flooding on the lake side.
A much larger project to build up levees along the lake and extend the shoreline out by dredging began in 1927. As the city grew, there was increased pressure to develop lower-lying areas. A large system of canals and pumps was constructed to drain the land. Flooding containment efforts until the mid-20th century primarily focused on floods from the Mississippi River.
In 1947, the Fort Lauderdale hurricane struck the New Orleans area. There was moderate wind damage. Flood prevention was largely successful in Orleans Parish, but there was severe flooding in the new East Jefferson suburbs near the Lake.
Late 20th century hurricanes
The heavy flood damage caused by Hurricane Betsy brought concerns about hurricane flooding to the forefront. Betsy resulted in a major redesign of the levee system. By authorizing the United States Army Corps of Engineers to design and construct the flood protection, Congress essentially overrode responsibility for flood protection by the local levee boards. The Flood Control Act of 1965 directed the Corps of Engineers to plan for the maximum anticipated hurricane for the area. (This project was still under construction when the city was struck by Katrina 40 years later.)
The Corps of Engineers also designed a Lake Pontchartrain Hurricane Barrier to shield the city with flood gates like those which protect the Netherlands from the North Sea. Congress provided funding, and construction began in 1971. But the work stopped in 1977 when a federal judge ruled, in a lawsuit brought by the environmental group Save Our Wetlands, that the Corps' environmental impact statement was deficient. In 1985, after nearly a decade of court battles, the Corps scrapped the plan, and decided to reinforce the existing levee system instead.[1]
The threat of 1969's Hurricane Camille was known in advance through improved radar technology and much of New Orleans braced for a repeat of Betsy. But Camille turned east and wreaked havoc on the Gulf coast of Mississippi and Alabama.
Hurricane Juan (1985) prompted a large evacuation from the city but did little damage.
Hurricane Andrew threatened the city in 1992. Clearly a major killer storm which had already devastated parts of south Florida, it prompted the largest evacuation of the city to date. Andrew turned west of the city but prompted re-evaluation of emergency evacuation procedures.
Georges missed the city, but it caused significant storm surge, raising the level of Lake Pontchartrain to the point that the city was spared major flooding only by the lake levees and flood walls. There was significant destruction to the areas just outside the flood walls, including at Little Woods [?] and at West End near the mouth of the 17th Street Canal.

Hurricane Isidore
Hurricane Isidore in 2002 prompted some cautious New Orleanians to evacuate; the majority kept an eye on the news without leaving town. A state of emergency was declared a few days before landfall, and a curfew was also issued between 6 am and 10 pm. The Superdome was used as a "special needs" shelter for medical patients.[7] There was relatively minor damage in the city; however, there was still some moderate flooding, with portions of Interstate 10 being closed due to rising water and the French Quarter being almost a foot underwater. The storm also shut down the Audubon Zoo.[8]
LSU-USACE Study
In 2002 the Corps of Engineers, in conjunction with the Louisiana Water Resources Research Institute at
Hurricane Ivan
In 2004 Hurricane Ivan's threat to the city resulted in the largest evacuation of the city to date. Mayor Ray Nagin issued a call for a voluntary evacuation of the city at 6 pm on September 13. An estimated 600,000 or more evacuated from Greater New Orleans. The contraflow plan was put into full effect for the first time, but rather late in the evacuation due to various confusions. This proved valuable practice, for the contraflow was implemented much more smoothly in 2005.
Hurricane Pam exercise
Hurricane Pam was a hypothetical hurricane used as a disaster scenario to drive planning for a 13-parish area in Southeastern Louisiana, including the city of
Follow-on Hurricane Pam workshops were conducted in November/December 2004, July 2005, and August 2005.
The Hurricane Pam scenario and the level of attention that the federal government paid to it were discussed following the catastrophic effects of Hurricane Katrina on New Orleans in November and December 2005.[14][15]
On January 25, 2005, the Louisiana Sea Grant forum discussed additional results of several simulations of strong hurricanes hitting New Orleans.[16]
Hurricane Cindy
Hurricane Cindy hit Louisiana at just barely hurricane strength on July 5, 2005. Many New Orleanians paid it little attention in advance, some having gotten blasé about threats of hurricanes which for decades had missed the city. However, Cindy's winds gusted to 70 mph (110 km/h) in the city, knocking branches off trees and causing New Orleans' largest blackout since Hurricane Betsy in 1965.[17] The experience encouraged many to evacuate when the much more powerful Hurricane Katrina was heading towards the city less than two months later.[18][19][20]
Hurricane Katrina
There were many predictions of hurricane risk in New Orleans before Katrina.[21][22][23]
On August 26 the storm, at one point up to a Category 5, was in the Gulf with a projection to possibly hit New Orleans a few days later. (The previous day the projected path was towards the Florida Panhandle.) On August 27 Mayor Nagin declared a state of emergency and called for a voluntary evacuation. The following day he issued the city's first ever whole-city mandatory evacuation order.[24] A mandatory evacuation order is an extreme measure: the most recent such order in Louisiana occurred when east New Orleans was ordered evacuated in 1965.
There have been various plans to mitigate or prevent catastrophes. The evacuation plans were the most successful. The contraflow worked relatively smoothly, and over 80% of the population succeeded in fleeing the area in advance of the storm. The evacuation no doubt saved thousands of lives. However, beyond the evacuation of those willing and able to leave town through their own resources, almost every other aspect of preparedness was found wanting.
Like many other cities, New Orleans heavily relied on evacuation in case of a Category 5 storm. The inadequacy of evacuation plans was shown when no provision was made in time to evacuate the large number of people– elderly, disabled, those without cars– who could not leave by their own means.
Blame for lack of preparedness has been leveled at all levels of government. New Orleans Mayor Ray Nagin had been criticized for not following the city's evacuation plan which called for the use of school buses to transport disadvantaged and elderly citizens out of the city. Louisiana Governor Kathleen Blanco was also criticized for not deploying the Louisiana National Guard sooner, although she did in fact deploy them before the hurricane hit and requested reinforcements from other states. Blanco asked for additional resources from the federal government, but refused to declare martial law or a state of emergency.[25] Disorganization began when the Louisiana Governor declined a proposal from the White House to put National Guard troops under the control of the federal government.[25] President George W. Bush and Homeland Security Secretary Michael Chertoff were also criticized for failures on the federal level as well as with his leadership role.[26] FEMA chief Michael D. Brown admitted on the 1 year anniversary of landfall that there was no plan,[27] and claimed that in the immediate aftermath of the disaster White House officials told him to lie to put a more positive spin on the Federal response.[28]
Hurricane relief plan vs. non-existent flood relief plan
One of the most significant planning failures was that there was no plan for the effects of a levee breach with the mass flooding that would result. After a typical hurricane hit the region, the plan would be for disaster relief forces to reach the city by overland routes. Since there was no New Orleans mass flooding and isolation by flooding plan, the plan that was pulled off the books was the hurricane relief plan. This plan failed because the relief personnel, most of whom were in trucks, could not get past nor through the areas that were under water. That there was no mass flooding relief plan to be executed was obvious by the lack of any heavy-lift helicopters such as Chinooks in relief forces that would have replaced the usual truck-born hurricane relief forces. A mass flooding with regional isolation plan would not have used land-based relief forces at all overland relief was impossible because of the barrier in place with the flooding.

Civil order broke down, infrastructure failed, and some 80% of the city flooded. A few government responders, including Coast Guard helicopters and Louisiana Fisheries & Wildlife Boats, responded early and worked hard to save people stranded in the flooding, but their numbers were inadequate for the scope of the disaster. Private volunteers with boats assisted with rescue in great numbers, but significant Federal response was largely absent until 5 days after the disaster.
Post-Katrina
The next major hurricane threat to the city after Katrina came less than a month later, as Hurricane Rita headed towards the Gulf Coast as the city was still in ruins. Repopulation of some parts of the city had just begun[31] when it was canceled and the city ordered re-evacuation. The levee system again failed, re-flooding low-lying portions of the city such as the Lower Ninth Ward.[32]
Hurricane Ernesto in 2006 originally threatened Louisiana before hitting Florida, causing early preparations and rising oil prices.[33][34][35]
Making landfall in Louisiana on September 1, 2008 as a category two hurricane, Hurricane Gustav was the first to put large scale preparations in motion, although the storm was still in Caribbean on the third anniversary of Katrina. Locals were warned to prepare for a possible evacuation of the city. Additional National Guard units were called out, and a state of emergency was declared.[36][37][38] No "shelters of last resort" were to be used. Soon afterwards, 1.9 million people were evacuated from southern Louisiana, including 200,000 from the City of New Orleans. Contraflow lanes were again initiated.[39][40] Forty-three deaths occurred in Louisiana as a result of the storm.[41]
During the category four Hurricane Ida in August 2021, the post-Katrina levee system successfully defended the city, but some suburbs without levees or where levees were still under construction flooded.[42]
Levee preparations and funding issues
Southeast Louisiana Project funding:
2004:
- Corps of Engineers' request: $11 million
- Bush request: $3 million
- Approved by Congress: $5.5 million
2005:
- Corps of Engineers' request: $22.5 million
- Bush request: $3.9 million
- Approved by Congress: $5.7 million
2006:
- Bush request: $2.9 million[citation needed]
While no detailed proposals had yet been made to augment the New Orleans levee system to be capable of withstanding a
Starting in 2003, federal spending on the Southeast Louisiana Project was substantially reduced. Lt. General Carl Strock,
From 2001 through 2005, the Bush administration battled with Congress to cut a total of approximately 67% from the budgetary requests from the Corps of Engineers for levee augmentation projects in the New Orleans area, but ultimately settled with Congress on a 50% cut in these budgetary requests. In February 2004, Al Naomi, a project manager for the Corps of Engineers, stated that, "I've got at least six levee construction contracts (in the New Orleans area where funding has been cut) that need to be done to raise the levee protection back to where it should be (because of settling). Right now I owe my contractors about US$5 Million. And we're going to have to pay them interest."[45]
Even as the Bush administration was cutting the Corps of Engineers' budget, many were criticizing the administration for not cutting the budget more. The
Just after Hurricane Katrina hit, there was some concern expressed that government officials had placed an overemphasis on disaster recovery, while neglecting the process of pre-planning and preparation.[46]
In the 17 months following Katrina, five investigations were carried out. The only federally ordered study was conducted by the American Society of Civil Engineers and paid for by the United States Army Corps of Engineers.[47] Two major independent studies were done by the University of California at Berkeley[48] and Louisiana State University.[49] Two minor studies were done by FEMA and the insurance industry. All five studies basically agree on the engineering mechanisms of failure.
The failure mechanisms included overtopping of levees and floodwalls by the storm surge, consequential undermining of flood wall foundations or other weakening by water of the wall foundations, and the storm surge pressures exceeding the strength of the floodwalls. In June 2006, a contrite Lt. Gen Carl Strock took responsibility for the failure of metro New Orleans flood protection, calling the system "a system in name only."[50]
As of August 2006, the Corps of Engineers planned to spend $6 billion to make sure that by 2010, the city would probably be flooded only once every 100 years. But this would not equal the best levee system in the world, which is in The Netherlands. That system is designed to protect populated areas against anything but a 1-in-10,000-years flood. If the Corps built a 1-in-500-year levee system in New Orleans, Ivan van Heerden, deputy director of Louisiana State University's Hurricane Center, says, it would cost $30 billion.[51]
According to a study by the
The impact of Louisiana's sinking coast
When the
However, an
The problem with the wetlands was further worsened by salt water intrusion caused by the canals dug by the oil companies and private individuals in this marshland. This erosion of the wetlands not only caused Louisiana to lose 24 square miles (62 km2) per year of land annually and 1,900 square miles (4,900 km2) of land since the 1930s, but it also destroyed Louisiana's first line of defense against hurricanes.[53]
Hurricanes draw their strength from the sea, so they quickly weaken and begin to dissipate when they make landfall. Hurricanes moving over fragmenting marshes toward the New Orleans area can retain more strength, and their winds and large waves pack more speed and destructive power. Scientists working for the Louisiana Department of Natural Resources measured some of these effects during Hurricane Andrew in 1992. Andrew's surge height dropped from 9.3 feet (2.8 m) at Cocodrie to 3.3 feet (1.0 m) at the Houma Navigation Canal 23 miles (37 km) to the north. For every mile of the marsh-and-water landscape it traversed, it lost 3.1 inches of height, sparing some homes farther north from more flooding. Currently Louisiana has 30% of the total coastal marsh and accounts for 90% of the coastal marsh loss in the lower 48 states. The engineering of the river has basically brought the Gulf of Mexico much closer to New Orleans, making it more vulnerable to hurricanes.
The combination of sinking land and rising seas has placed the Mississippi River delta as much as 3 feet (0.91 m) lower relative to sea level than it was a century ago,[53] and the process continues. That means hurricane floods driven inland from the Gulf have risen by corresponding amounts. Storms that once would not have had much impact can now be devastating events, and flooding now penetrates into places where it has rarely occurred before. The problem also is slowly eroding levee protection, cutting off evacuation routes sooner and putting dozens of communities and valuable infrastructure at risk of being wiped out by the flooding.
State and federal officials have recently pushed a $14 billion plan to rebuild wetlands over the next 30 years, to be funded by oil and gas royalties, called Coast 2050. [53][54] Louisiana will receive US$540 million under the energy bill enacted in August 2005. More money for this program is likely to come with aid from Hurricane Katrina. The original actual cost needed for the project, however, was $14 billion.[53]
Wetlands have the capacity to absorb storm surges at the rate of 1-foot (0.30 m) per 2.7 miles (4.3 km). However, due to the systematic, long-term nature of wetland loss,[22] and because wetland remediation can take decades,[55] it is not possible to pinpoint blame for wetland loss on any specific Congress, legislature, President, or governor.
