Adаm Bros. Farming, Inc. and Iceberg Holdings, L.L.C. (collectively “Adam Bros.”) appeal from the district court’s dismissal of their joint complaint. Adam Bros, sued the County of Santa Barbara and several of its employees (collectively “the county”) in federal court, alleging that the county had, through a false wetland delineation, temporarily taken its land without providing just compensation in violation of the Fifth Amendment. The district court granted the county’s motion to dismiss and concluded that Adam Bros.’s claim was not ripe because Adam Bros, failed to demonstrate that it had sought and was denied just compensation under state law. Because we conclude that Adam Bros.’s claim is barred by the application of res judicata, we affirm the district court’s judgmеnt.

This case concerns a 268.5 acre parcel of land located in Santa Maria, California, commonly known as Rancho Meadows. On July 22,1997, the Santa Barbara County Board of Supervisors adopted a community plan delineating a 95-acre tract of Rancho Meadows as wetland. The community plan complied with the applicable notice requirements.
*1145 Unaware of the wetland restriction, Bernadette and Richard Adam Sr. purchased Rancho Meadows for $2.3 million on November 26, 1997, after conducting a title search. The Adams immediately transferred Rancho Meadows to Iceberg Holdings, L.L.C., which then leased it to Adam Bros. Farming, Inc. 1 Adam Bros, soon discovered the wetland restriction. Its investigations, however, reveаled that the wetland designation was both factually incorrect and improperly made.
When the county developed its community plan, it delineated 95 acres of Rancho Meadows as wetland, even though prior environmental reports showed that no wetland existed on the property. To support its delineation, the county hired a biologist, Katherine Rindlaub, to perform a wetland evaluation according to the Army Corps of Engineers Manual guidelines. The county insisted that Rindlaub perform the evaluation even though Rindlaub informed the county that she was unqualified to do so and that she had no experience with the Army Corps of Engineers Manual. Without performing hydrology or soil testing and without physically examining 80% of Rancho Meadows, Rindlaub issued a report indicating that the 95-acre tract at issue was a wetland. Although Rindlaub informed the county that her report was deficient, the county relied on it to adopt its community plan.
Between May and August 1998, Adam Bros, exchanged a series of letters with the county regarding its ability to farm Rancho Meadows. The county responded that Adam Bros, could farm the land only with ■ a grading permit. Adam Bros, had already concluded that no wetland existed on Rancho Meadows, however, so it did not apply for a grading permit. Instead, Adam Bros, challenged the county’s permit requirement in an attempted appeal, which the county refused to process.
In December 1998, the county reinterpreted its grading ordinance, allowing agricultural grаding without a permit. Adam Bros, began grading Rancho Meadows. In February 1999, the county again reinterpreted its grading ordinance and returned to its original position of requiring a permit for agricultural grading. Adam Bros, continued to grade Rancho Meadows, however, and on March 30,1999, the county issued a stop work order.
On March 29, 2000, Adam Bros, sued the county in the Superior Court of Californiа seeking damages and declaratory and injunctive relief for inverse condemnation and violations of the federal Equal Protection, Due Process and Takings Clauses. The complaint alleged that the county and its employees improperly delineated part of Rancho Meadows as wetland and supported that delineation with false repоrts. The Superior Court dismissed the complaint based on its conclusion that the inverse condemnation and takings claims were not ripe because Adam Bros, had not adequately pursued administrative remedies. Adam Bros, then filed an amended complaint without the takings and inverse condemnation claims. 2 The court dis *1146 missed that complaint with prejudice, and Adam Bros, appeаled.
The California Court of Appeal reversed the Superior Court’s dismissal and held that Adam Bros.’s substantive due process and equal protection claims were ripe because there had been a “final administrative decision concerning the challenged government action.”
Adam Bros. Farming, Inc. v. County of Santa Barbara (Adam Bros. I),
No. B152770,
On November 22, 2004, following a 13-day trial, the jury rendered several special verdicts in favor of Adam Bros., including that (1) the county’s wetland delineation was improper under the Army Corps of Engineers Manual, (2) the county violated Adam Bros.’s due process and equal protection rights and (3) Adam Bros, was entitled to compensatory damages totaling $5.4 million and punitive damages totaling $130,000. The- Superior Court followed this verdict with a bench trial in which it issued injunctive and declaratory relief invalidating the county’s wetland delineation. The county appealed.
On aрpeal, the California Court of Appeal affirmed the injunctive and declaratory relief,- but reversed the jury’s award of damages.
Adam Bros. Farming, Inc. v. County of Santa Barbara (Adam Bros. II),
No. B180880,
Adam Bros, then filed this action in federal district court, alleging a violation of the Fifth Amendment’s Takings Clause. The county moved the court to dismiss Adam Bros.’s complaint under Federal Rule of Civil Procedure 12(b)(6). The district court granted that motion based on its conclusion that Adam Bros, had not satisfied the ripeness requirements of

A
For a Fifth Amendment takings claim to be ripe for review, the party bringing the challenge must overcome two “prudential hurdles” first presented by the
*1147
Supreme Court in
Williamson County. Suitum v. Tahoe Regl Planning Agency,
First, a final decision exists when (1) a decision has been made “about how a plaintiffs own land may be used” and (2) the local land-use board has exercised its judgment rеgarding a particular use of a specific parcel of land, eliminating the possibility that it may “soften[ ] the strictures of the general regulations [it] administer[s].”
Suitum,
Here, the county made a decision regarding Adam Bros.’s agricultural grading of Rancho Meadows and enforced that decision by issuing a stop work order, applying its judgment to Adam Bros.’s specific activities on Rancho Meadows and establishing the boundaries of the grading ordinance. Before the county issued its stop work order, Adam Bros, communicated extensively with the county to determine its rights. During this time, the county demonstrated that the boundaries of its grading ordinance were not concrete by twice reinterpreting the regulation. By the time Adam Bros, began to grade Rancho Meadows, though, the county reached a conclusion as to the meaning of its grading-ordinance and issued a stop work order, creating a final, concrete harm.

Furthermore, the California Court of Appeal decision in
Adam Bros. II
represents a “final state judgment denying just compensation,” as there remains no possibility that the county will provide Adam Bros, with compensation absent a decision of this court.
San Remo Hotel, L.P. v. City & County of S.F.,
Second, a plaintiff bringing a takings claim must have “unsuccessfully attempted to obtain just compensation through the procedures provided by the State.”
Williamson County,
When the state prоvides a procedure by which a party may seek just compensation, such as an inverse condemnation cause of action, the plaintiff must seek relief in state court before bringing a claim

in federal court.

Under one reading of Williamson Coun ty, if Adam Bros, had successfully obtained damages on its due process and equal protection claims, its alleged injuriеs would have been redressed and its takings claim would have been mooted. Because an award of damages on these claims would have redressed Adam Bros.’s alleged injuries, it could be fairly said that Adam Bros, has requested and been denied just compensation from the state. Still, under another reading, California provides its own cause of action for addressing an alleged taking, and the state is free to require additional procedure, such as administrative exhaustion, with which a party must comply to proceed with that claim. If asserting a federal cause of action in state court would ripen a federal takings claim, a party would effectively be able to bypass any additional state procedures by relying on federal law. The party would then be awarded with a second bite at the apple in federal court if unsuccessful in state coui’t. Still, we ultimately do not need to adopt either reading of Williamson County and so we decline to do so.
As this case raises only prudential concerns,

we have the discretion to waive the requirements of
Williamson
County, assume that ripeness is met and continue with our analysis.

Judicial proceedings of any state “have the same full faith and credit in every court within the United States ... as they have by law or usage in the courts of such State.” 28 U.S.C. § 1738. Also, it is well-established that state courts are fully competent to hear federal claims, including constitutional challenges to land-use regulations.
See San Remo Hotel, L.P. v. City & County of S.F.,
Under California law, res judicata precludes a party from relitigating (1) the
*1149
same claim, (2) against the same party, (3) when that claim proceeded to a final judgment on the merits in a prior action.
See Mycogen Corp. v. Monsanto Co.,
Two different causes of action are the same claim if they rise from the same invasion of a “primary right.”
Id.
at 306. A plaintiffs primary right is “the right to be free from a particular injury, regardless of the legal theory on which liаbility for the injury is based.”
Fed’n of Hillside & Canyon Ass’ns v. City of L.A.,
The primary right theory is a theory of code pleading ... that provides that a “cause of action” is comprised of a “primary right” of the plaintiff, a corresponding “primary duty” of the defendant, and a wrongful act by the defendant constituting a breach of that duty. The most salient characteristic of a primary right is that it is indivisible: the violation of a single primary right gives rise to but a single cause of action.
Crowley v. Katleman,
The substance of Adam Bros.’s state and federal complaints is nearly identical. Both complaints allege that the county and its employees improperly delineated 95-acres of Rancho Meadows as a restricted wetland, and both complaints assert that Adam Bros, was injured by this delineation because it could not farm Rancho Meadows as it had intended. The damages that Adam Bros, now seeks to obtain in federal court are identical to those it sought in state court. For purposes of res judicata, it is irrelevant that Adam Bros, attempts to recover under different legal theories.
See Mycogen,
Adam Bros, argues that its present temporary takings claim cannot be the same claim for purposes of res judicata because this claim could not have been brought and did not exist until after the California court invalidated the county’s false wetland designation. Yet its present claim is still based on the same underlying factual circumstances as the claims it raised in statе court. The particularities of Adam Bros.’s causes of action are irrelevant. Neither does the fact that the Superior Court dismissed Adam Bros.’s takings claim without prejudice immunize those claims from preclusion. 5 Adam Bros.’s claim is barred by res judicata.

San Remo
supports our conclusion. In

AFFIRMED.
Notes
. The Adams created Iceberg Holdings, L.L.C. to hold title to its land and created Adam Bros. Farming, Inc. to conduct its farming activities. These parties are referred to thrоughout as "Adam Bros.” collectively.
. In state court, the county argued that Adam Bros.'s Fifth Amendment takings claim was not ripe because it had not yet brought an inverse condemnation cause of action. The county further argued that Adam Bros.'s inverse condemnation claim was not ripe because it had not yet requested a writ of mandate. At oral argument, Adam Bros, explained that it strategically chtise to proceed on its due process and equal protection claims rather than expending additional resources to comply with or argue against the county's above claims.
. Insofar as estoppel could be an issue, our conclusion is consistent with that of the California Court of Appeal.
See Adam Bros. I,
. Regarding Article III, or jurisdictional, ripeness, Adam Bros.'s alleged injury is not "too 'imaginary' or 'speculative' to support jurisdiction."
Thomas v. Anchorage Equal Rights Comm’n, 220
F.3d 1134, 1139 (9th Cir.2000). Nor would adjudication of the issue before us be premature at this point in time.
Stormans, Inc. v. Selecky,
. After the dismissal without prejudice, Adam Bros, chose to file an amended complaint that omitted the takings and inverse condemnation claims. Res judicata bars "not only claims actually litigated in a prior proceeding, but also claims that could have been litigated.”
