OPINION
Plaintiffs appeal the dismissal of their federal takings claim against the City of Columbus. They alleged that the City unconstitutionally deprived them of their well-water by digging a trench to extend a sewer pipeline. The district court dismissed their claim as barred by the statute of limitations. Because it ripened around 1992 — then beginning the two-year statute of limitations period — we affirm.
I.
In 1990, the City of Columbus decided to extend a sewer line. To do so, the defendants (the City along with several private entities), created a dry trench by pumping groundwater out from the plaintiffs’ property to clear the way. For purposes of this proceeding, the defendants have stipulated that this “dewatering” activity caused the plaintiffs’ wells to run dry. Before filing this federal action, in 1992 the plaintiffs filed a complaint in state court alleging that the defendants committed a state tort, the unreasonable use of their groundwater. After some machinations and various appeals, the state courts ultimately rejected this claim. Keeping hope alive, they filed this suit in federal court in 1999, alleging a federal takings claim and a procedural and substantive due process claim under 42 U.S.C. § 1983. The district court first concluded that Ohio does not recognize a property interest in groundwater — so there was nothing for the state to take — and granted summary judgment to the defendants. This Court on appeal certified to the Supreme Court of Ohio the question whether “an Ohio homeowner [has] a property interest in so much of the groundwater located beneath the land owner’s property as is necessary to the use and enjoyment of the owner’s home.” The Supreme Court of Ohio answered in the affirmative.
McNamara v. City of Rittman,
So we reversed the district court’s original decision and remanded for reconsideration. After additional briefing and argument, it again dismissed the plaintiffs’ takings claim, this time as barred by the statute of limitations. The plaintiffs now appeal.

“The Fifth Amendment does not proscribe the taking of property; it proscribes taking without just compensation.”
Williamson County Reg’l Planning Comm’n v. Hamilton Bank,
This first hurdle requires that the taking be “final.” With a “physical taking,” the taking itself is viewed as a final action because, once the property’s value has been allegedly destroyed, there is nothing else to do.
See Coles v. Granville,
A.
We are faced with an accrual question: when did the plaintiffs’ takings claim ripen? The answer tells us when the statute of limitations began to run.

Typically, federal takings claims may not be heard in federal court until the plaintiffs have first pursued just compensation using the procedures the state has provided, usually via “inverse condemnation” proceeding.
See, e.g., Braun v. Ann Arbor Charter Twp.,
Here, both parties agree that the applicable statute of limitations is only two years, Ohio Rev.Code § 2305.10, and that it “starts to run when the plaintiff knows or has reason to know of the injury which is the basis of the action.”

Plaintiffs also assert that, notwithstanding that their claim would ordinarily have expired by now, they nevertheless benefit from the “continuous violation” doctrine so their claim is still live. This doctrine is rooted in general principles of common law and is independent of any specific action.
See, e.g., Heard v. Sheahan,
Unlike in McNamara, however, the plaintiffs here do not suffer from a “continuous violation.” In that case, the City drilled multiple wells near the plaintiffs’ property, and operating those wells provided the City with between 500,000 and 750,000 gallons of water per day. Id. at 635. The McNamara plaintiffs claimed that both the initial drilling and the continual operation of the wells lowered their aquifers such that, were operations to stop, their aquifer would replenish. Id. This Court dismissed the claims related to the initial drilling as barred by the statute of limitations, but dismissed the claims related to the continuous operation and pumping of the wells as unripe because, while that constituted a continuous violation, the plaintiffs had not availed themselves of Ohio’s mandamus procedure. Id. at 639-40. Here, by contrast, while the City of Columbus built a dry trench by pumping out groundwater to extend a local sewer line, the water level of their wells does not depend on any continual intervention by the state: once the trench was constructed in 1992, the cessation of activity would have done nothing for the defendants. In other words, the damage was done, and, unlike the McNamara plaintiffs, no ongoing state activity gave rise to a continuous violation that would justify resetting the statute of limitations clock. Thus, the *698 plaintiffs’ claim ripened in 1992 and is now barred by the statute of limitations. 4

For the above reasons, we AFFIRM the judgment of the district court.
Notes
. "[T]he procedural [and substantive] due process claim[s] in this case [are] not independent of the underlying takings claim, [so] ripeness analysis for the takings claims necessarily subsumes ripeness analysis for the due process claim[s].”
McNamara v. City of Rittman,
. Because the distinction between "regulatory” and "physical takings" is "fuzzy at best,” this Court has held that "it is wholly immaterial whether the alleged taking is styled as "physical” or "regulatory” in the context of the just compensation requirement.”
River City Capital, L.P. v. Bd. of County Comm’rs,
."This court reviews de novo a district court’s holding that a legal claim is barred by the applicable statute of limitations period.”
