The language is plain. Section 3 of the Flood Control Act of 1928 reads:
"No liability of any kind shall attach to or rest upon the United States for any damage from or by floods or flood waters at any place."
The sentence is fifty-one years older than FEMA. It is still the law.
Congress passed the Act in the aftermath of the Great Mississippi Flood of 1927, which killed roughly 500 people, displaced more than 630,000, and inundated 27,000 square miles of the lower Mississippi Valley. The federal government had a record budget surplus that year. Not a dollar of federal money went in direct aid to any of the one million flood victims. The Act that followed was designed to make the levees stronger. What happened to the people behind them when the levees failed was left unaddressed.
Three compromises embedded in the legislation determined the shape of American disaster response for the next century. The legislators who wrote them understood exactly what they were authorizing and what they were leaving out.
The first was sovereign immunity. The blanket language of Section 3 meant the federal government could build, maintain, and operate flood control infrastructure without ever being held responsible for its failure. In 2009, Federal Judge Stanwood Duval of the Eastern District of Louisiana held the Army Corps responsible for design defects in the 17th Street Canal floodwall that collapsed during Hurricane Katrina. He then ruled the Corps could not be held financially liable.
"When Congress grants immunity to the 'sovereign,' in essence, the King can do no wrong."
Eighty-one years separated the Act from the ruling. The immunity held without strain.
The second compromise was cost-sharing. Section 2 declared it "the sense of Congress" that local contribution toward flood control was sound, "recognizing the special interest of the local population in its own protection." States and levee districts had to provide rights-of-way without cost to the United States and maintain all works after completion. The $325 million in authorized appropriations flowed through the Mississippi River Commission, which had been building levees since 1879 along the main stem between Cape Girardeau, Missouri and the Head of Passes. Communities within the commission's existing levee districts, places with organized political infrastructure and the fiscal capacity to meet federal matching requirements, received protection. Communities outside that system, the smaller tributaries, the unincorporated stretches, the places without a levee board or a senator's son on the relief committee, received less or nothing. No community was excluded by name. The cost-sharing formula simply assumed capacities that mapped onto existing wealth, and the map held.
The third compromise was silence. The Act authorized the largest public works appropriation in American history for levees, spillways, and channels. It authorized nothing for the people those structures were meant to protect. The same levees that held families during the flood became, in the Act's architecture, federal property worth protecting. The families behind them did not become a federal responsibility. Infrastructure received $325 million. Individual relief received silence.
That silence lasted twenty-two years. Before 1950, when Congress passed the Federal Disaster Relief Act, there was no permanent federal authority for helping disaster victims. Congress passed 128 separate laws between 1803 and 1950 to provide ad hoc relief for individual disasters. Each required its own political negotiation. Each expired.
Even after 1950, the gap between infrastructure protection and individual assistance remained structural. Disaster responsibilities fragmented across more than 100 federal agencies. Federal spending ballooned from roughly $7 million annually in the 1950s to over $1 billion by the late 1970s, scattered across departments and programs with overlapping mandates and no coordination. FEMA's creation in 1979 through Executive Order 12127 was supposed to resolve this. President Carter consolidated disaster-related responsibilities into a single agency. But FEMA inherited the legal architecture the 1928 Act had established. The agency could coordinate response and fund mitigation. Sovereign immunity and cost-sharing formulas that channeled protection toward communities already positioned to receive it remained beyond its authority. The asymmetry between infrastructure and individual relief was baked into the foundation FEMA was built on.
In 2003, FEMA lost its independent status and was absorbed into Homeland Security. Katrina exposed what the structure had always contained: a system that could build levees and disclaim responsibility when they broke, that could process applications and deny most of them, that could exist as the name Americans associated with disaster help while the help itself remained constrained by compromises made before anyone in the agency was born.
Now the agency faces dismantling. The current administration has proposed pushing disaster response back to the states, cutting FEMA's workforce and eliminating grant programs that funded local hazard mitigation. If that happens, the country returns structurally to something resembling the pre-1950 arrangement, where outcomes track geography, fiscal health, and political will. The 128 ad hoc laws Congress once passed, one disaster at a time, at least represented a willingness to act when the water was still in the streets. They also represented something the 1928 Act's framers would have recognized: a system where the communities with the most political leverage got helped first, and the rest waited.
The phrase "safety net" implies something woven tight enough to hold. The Flood Control Act of 1928 wove the first strands. They were engineered for concrete and steel. Around people, the gaps were there from the beginning. They were compromises, made deliberately, by legislators who understood what they were choosing and what they were leaving out. The architecture has been renovated, renamed, reorganized, and now threatened with demolition. The gaps have never been filled.
