In a significant development for property owners affected by government flood-control operations, the U.S. Court of Federal Claims has ruled that the federal government may be liable under the Fifth Amendment for downstream flooding caused by its decision to release water from the Addicks and Barker Dams during Hurricane Harvey. This decision addresses the other side of the same system that gave rise to the now well-known upstream cases: instead of water being held back and flooding upstream properties, this case focuses on the consequences of water being released downstream.
As a firm that has remained involved in both the upstream and downstream takings litigation related to Hurricane Harvey, this decision is an important addition to the growing body of law recognizing that flood-control decisions—whether to hold water or release it—can give rise to constitutional liability when they impose predictable, physical invasions on private land.
Background: The Addicks and Barker System During Hurricane Harvey
The Addicks and Barker Dams, constructed and operated by the U.S. Army Corps of Engineers, are designed to reduce flood risk in the Houston area by storing stormwater during heavy rainfall events and releasing it over time. During Hurricane Harvey in August 2017, the region experienced unprecedented rainfall, and the reservoirs behind the dams filled to record levels.
At that point, the Corps faced operational choices governed by its Water Control Manual. One provision—referred to in the decision as the “Induced Surcharge Flood Control Regulation”—authorized the Corps to release water in a way that could increase downstream flooding under certain conditions. Acting pursuant to that authority, the Corps released large volumes of water into the downstream watershed and surrounding waterways.
Downstream property owners alleged that these releases caused or substantially worsened flooding of their homes and businesses. They brought suit in the Court of Federal Claims, asserting that the government had committed a taking of their property without just compensation.
Framing the Case: Not the Dam, But the Decision
A central feature of the court’s analysis is how it framed the source of the alleged taking. The plaintiffs did not challenge the existence of the dams themselves, nor did they argue that the entire flood-control system was unconstitutional. Instead, they focused on a specific operational decision: the Corps’ choice to release water under the governing manual during Harvey.
That distinction mattered. After narrowing the claim to a discrete government action, the court analyzed whether that action—standing on its own—caused a compensable physical invasion of private property. This approach aligns with prior flooding cases in which liability turned on how the government operated a project, rather than the mere fact that the project existed.
Causation: What Is the Right Comparison?
One of the most contested issues in the case was causation. Specifically, what baseline should be used to determine whether the government caused the flooding?
The government argued that the proper comparison was a world in which the dams did not exist at all. Under that theory, downstream flooding might have been just as severe, or even worse, without the dams, meaning the Corps’ actions could not be said to have caused plaintiffs’ injuries.
The court rejected that framing. Instead, it adopted a more focused comparison regarding what would have happened if the Corps had not made the challenged releases during Hurricane Harvey. In other words, the relevant question was whether the decision to open the gates and release water increased flooding beyond what would have occurred had the government refrained from that specific action.
This choice of baseline is critical. By focusing on the Corps’ operational decision rather than the existence of the broader project, the court made it possible for plaintiffs to demonstrate that the government’s conduct directly caused additional flooding.
The court concluded that the plaintiffs had established a compensable taking under the Fifth Amendment. The key to that conclusion was the nature of the invasion: water physically entering and damaging private property.
A Physical Taking by Flooding
The court concluded that the plaintiffs had established a compensable taking under the Fifth Amendment. The key to that conclusion was the nature of the invasion: water physically entering and damaging private property.
Even though flooding may come and go, the law treats government-induced flooding as a physical taking when it is the predictable result of government action. The court emphasized that the Corps acted pursuant to a defined operating procedure, and that downstream flooding was not an accidental byproduct but a known consequence of the release decision under certain conditions.
The court further explained that the intentional flooding amounted to both a temporary and permanent taking. On the one hand, the flooding associated with Hurricane Harvey could support a temporary takings theory, given its duration and intensity. On the other hand, because the same operating rules remain in place and could lead to similar releases in future storms, the government’s actions may also amount to the acquisition of a recurring right to flood downstream properties.
This dual framing as temporary and permanent reflects the flexibility courts have developed in analyzing flooding cases and ensures compensation for those affected by potential Addicks and Barker operations in the future.

Foreseeability and the Scope of the Project
Another important issue was whether the flooding experienced by plaintiffs was within the “scope of the project” as originally conceived. The government argued that downstream impacts were part of the overall flood-control system and therefore should not give rise to liability.
The court disagreed. It focused on whether a reasonable property owner, at the time the project was undertaken, would have anticipated the specific type of flooding caused by the induced releases at issue. The court concluded that the challenged conduct—releasing water in a manner that increases downstream flooding under certain conditions—was not something that would have been understood as an inherent or inevitable feature of the original project.
That finding helped distinguish this case from situations in which property is acquired or burdened with known limitations at the outset of a government project.
The Government’s Defenses
The government raised several defenses, all of which the court ultimately rejected.
First, the government invoked a form of “necessity,” arguing that it had to release water to protect the structural integrity of the dams. The court closely examined the factual record and found that the releases were made pursuant to established operating procedures rather than in response to a sudden, unforeseen emergency. That information undercut the notion that the government was acting under the kind of immediate necessity that might excuse compensation.
Second, the government relied on the idea that the flood-control system as a whole provided net benefits to the region. While the court did not dispute that the dams serve an important public purpose, it explained that the Takings Clause focuses on the burden imposed on individual property owners, not on general regions. The fact that a project benefits the public at large does not allow the government to impose disproportionate costs on a subset of landowners without compensation.
Finally, the government suggested that downstream owners effectively assumed the risk of flooding. The court rejected that argument as well, emphasizing that property rights include protection against government-induced invasions unless and until the government acquires that right through payment.
Why This Decision Matters
This decision is notable because it extends takings principles to the downstream consequences of flood-control operations. Much of the recent litigation surrounding Hurricane Harvey and the Addicks and Barker system has focused on upstream flooding caused by water being held back. This case demonstrates that liability can also arise when the government chooses to release water in a manner that foreseeably increases flooding on private land.
For property owners, the ruling reinforces a simple but powerful principle: the government cannot avoid the Fifth Amendment by characterizing its actions as part of a broader public project. Whether the government is storing water or releasing it, the constitutional question remains the same—has the government caused a physical invasion of private property for public benefit without paying for it?

The decision also provides a roadmap for future cases. By focusing on discrete operational decisions, carefully defining the causation baseline, and analyzing foreseeability and project scope, the court offers a framework that other property owners may be able to use when challenging government-induced flooding.
Looking Ahead
As with many significant Court of Federal Claims decisions, the story may not end here. Issues such as causation, the proper baseline for comparison, and the characterization of flooding as temporary or permanent are likely to receive further scrutiny on appeal.
Even so, this decision represents an important step forward in holding the government accountable for the real-world consequences of its flood-control choices. It underscores that when the government deliberately shifts the burden of protecting the public onto a defined group of property owners, the Constitution requires that those owners be compensated.
