17th Street Canal Floodwall Breach
New Orleans, Orleans Parish, Louisiana
Marker Inscription
17th Street Canal Floodwall. On August 29th, 2005, a federal floodwall atop a levee on the 17th Street Canal, the largest and most important drainage canal for the city, gave way here causing flooding that killed hundreds. This breach was one of 50 ruptures in the Federal Flood Protection System that occurred that day. In 2008, the US District Court, Eastern District of Louisiana placed responsibility for this floodwall's collapse squarely on the US Army Corps of Engineers; however, the agency is protected from financial liability in the Flood Control Act of 1928.

The Story
On August 29, 2005, as Hurricane Katrina struck New Orleans, the federal floodwall along the vital 17th Street Canal gave way at this spot, unleashing floodwaters that killed hundreds. It was one of some fifty failures in the region's flood-protection system that day. A 2008 federal court laid the collapse at the feet of the Army Corps of Engineers, even as a 1928 law shielded the agency from financial liability.
Why it matters
The breach became a symbol of engineered and institutional failure in one of the deadliest disasters in modern American history.
The story behind this marker
AI contextThe era
By the summer of 2005, New Orleans was a city that lived by an unspoken bargain with water. Much of it sits below sea level, wedged between the Mississippi River and the vast, shallow bowl of Lake Pontchartrain. For generations, an elaborate machinery of levees, floodwalls, pumps, and drainage canals kept the water out and the streets dry. Residents grew up trusting that system the way people elsewhere trust solid ground.
The 17th Street Canal was the backbone of that machinery — the largest and most important drainage canal in the city, the artery that carried rainwater and runoff away toward the lake. A floodwall stood atop its levee, one line in a sprawling federal flood-protection system meant to hold the water at bay even in a serious storm.
When Hurricane Katrina came ashore on August 29, 2005, the Gulf Coast braced for wind and rain. But the deepest wound to New Orleans came not from the sky but from the water — and not over the walls, but through them. It was one of the defining moments in the story of American cities and the limits of the engineering meant to protect them.
People & events
On the morning of August 29, 2005, the floodwall on the 17th Street Canal gave way at this very spot. It was not a slow overtopping but a breach — the barrier failed, and the water it was built to hold poured into the neighborhoods behind it.
The flooding that followed killed hundreds. Whole districts went under, in some places to the rooftops, and families waited on porches and attics for rescue as the water kept rising. This was not an isolated accident: the marker records that the 17th Street failure was one of some fifty ruptures across the federal flood-protection system that single day. The city was not swamped by one great wave but bled by dozens of failures at once.
In the years that followed, the question turned from what happened to who was responsible. In 2008, the U.S. District Court for the Eastern District of Louisiana placed the blame for this floodwall's collapse squarely on the U.S. Army Corps of Engineers, the federal agency charged with the system's design. Yet, as the marker notes with quiet bitterness, a law dating to 1928 — the Flood Control Act — shielded the agency from financial liability. Responsibility was assigned; the account was never settled.
Its place in the American story
Katrina became one of the deadliest and costliest disasters in modern American history, and this narrow strip of concrete became a symbol of how it went so wrong. The story that hardened in the aftermath was not simply about a hurricane. It was about a protection system that Americans had been told would hold — and did not.
The distinction the marker insists upon matters: the walls did not merely spill over, they failed. That reframing turned a natural disaster into a man-made one, and it forced a national reckoning about aging infrastructure, deferred maintenance, and who bears the cost when public works break. The 1928 liability shield, invoked to protect the agency found at fault, sharpened a hard American question about accountability that reaches far beyond one city.
That this plaque was placed by a citizens' organization, rather than by a government body, is itself part of the meaning. It stands as a piece of remembering that ordinary people insisted upon — a refusal to let the failure be softened into an act of God.
If you visit
Standing here, you may be struck first by how ordinary the setting looks. This is not a dramatic ruin; it is a working canal in a residential city, with houses, streets, and everyday life pressing close. That ordinariness is the point. The disaster did not happen in some remote wilderness — it happened here, among people's homes.
Take a moment to notice the relationship between the water in the canal and the ground where you stand. Much of New Orleans sits below the level of the surrounding water, and once you feel that geography in your body, the stakes of a single failing wall become vivid in a way no statistic can match.
This is a memorial, so come to it in that spirit. It rewards a quiet, thoughtful visit rather than a quick photo. If you're building a New Orleans itinerary, let this stop deepen the rest: the music, the food, and the fierce local pride you'll encounter elsewhere in the city all carry the memory of what was lost and rebuilt here.

City Park Carousel
New Orleans, LA
The carousel in New Orleans's City Park has delighted riders since about 1906, its hand-carved animals and ornate pavilion making it a rare survivor of America's golden age of amusement rides. Lovingly restored in 1988, it is one of the last antique wooden carousels of its kind still turning. The National Register listing recognizes both the ride and its building.
Allard Plantation
New Orleans, LA
This land was once the Allard plantation, tied to some of colonial Louisiana's founding families. Purchased in the 1770s by Don Santiago Lorreins from the estate of Francisco Hery — called Duplanty, who built New Orleans's first Cabildo in 1769 — it passed to Louis Allard and, in 1845, to the philanthropist John McDonogh, who gave it to New Orleans in 1850. Like other Louisiana plantations of its era it was worked by enslaved laborers, and the tract later became the heart of the city's City Park.
Spanish Custom House
New Orleans, LA
For nearly four decades in the late 1700s, Louisiana was a Spanish colony, and New Orleans served as capital of the Province of Luisiana after France ceded the territory in 1762. This custom house on Moss Street, dating to 1784, recalls the era when Spanish officials collected duties on the goods and shipping that flowed through the busy Gulf port. The city's Spanish decades left lasting marks on its architecture, law, and street names before Louisiana passed back to France and then to the United States in 1803.
City of Metairie Ridge
Jefferson Parish, LA
In the summer of 1927, a twelve-square-mile stretch of Jefferson Parish incorporated first as a village and then, weeks later, as a city, with Charles P. Aicklen serving as mayor and bringing natural gas service the following year. But the young municipality moved to outlaw the gambling that flourished nearby, and casino interests fought back in court. By November 1928 the Louisiana Supreme Court had voided the incorporation entirely.
