In this appeal, Evandro S. Santini and his real estate development firm, Santini Homes, Inc., challenge a judgment of the United States District Court for the District of Connecticut (Warren W. Eginton, Judge) in favor of the Connecticut Hazardous Waste Management Service (the “Service”). After unsuccessfully pursuing a state-law takings claim in the Connecticut courts, Santini sued in federal court, alleging that the Service’s announcement that his property was one of three sites under consideration for the location of a low-level radioactive waste disposal facility constituted a taking without just compensation in violation of the Fifth Amendment. 1 The District Court dismissed Santi-ni’s complaint on three grounds: the Rooker-Feldman doctrine, 2 collateral es-toppel, and the merits of the takings claim.
*121
Because Santini did not raise, and could not have raised, his federal takings claim in the state court action, we conclude that the
Rooker-Feldman
doctrine and res ju-dicata do not apply. Moreover, we recognize an exception to the applicability of collateral estoppel for plaintiffs who litigate state-law takings claims in state court solely to comply with the ripeness requirement of
Williamson County Regional Planning Commission v. Hamilton Bank,
BACKGROUND
The material facts are undisputed. San-tón develops residential real estate in the area surrounding Hartford, Connecticut. In 1985, he purchased, for $147,500, a 20.3-acre parcel of land in Ellington, Connecticut. Santini obtained approval from the Ellington Planning and Zoning Commission to subdivide the parcel, to be known as Ellridge Estates, into sixteen lots. Beginning in 1985, Santini built an access road to the development, installed storm drainage and sewer systems, and, in all, spent approximately $500,000 developing infrastructure.
In 1988, Santini purchased, for $1,075,000, a 54.6-acre parcel (the “Pinney Street property”) adjacent to the Ellridge Estates parcel, intending to develop the two parcels into a unified 75-acre residential village consisting of approximately 100 homes. Santini began building model homes in 1987, constructing houses on four lots of the Ellridge Estates parcel. He also made other investments in the properties, including completing engineering studies and preliminary layouts for the Pinney Street property and borrowing funds for the construction of its infrastructure. Because of a recession in the real estate market, construction proceeded slowly until 1991. When market conditions improved, Santini renewed his efforts to sell homes in Ellridge Estates: he lowered prices, established a mortgage program customized to the development, and began advertising aggressively. By June 1991, he had identified likely buyers for two of the homes, spent $5 million in acquiring and developing the Ellington properties, and borrowed $4.7 million that was earmarked for further construction on the Pinney Street property.
The Service is a quasi-public governmental agency established pursuant to Connecticut General Statutes § 22a-163 et seq. and charged with siting a low-level radioactive waste disposal facility. The Low-Level Radioactive Waste Policy Act of 1980, 42 U.S.C. § 2021b et seq., required the states to make adequate provision for the disposal of low-level radioactive waste generated within their borders by entering into regional compacts, and it imposed financial penalties on those states that failed to do so. In 1986, with few states complying with the Act, Congress passed the Low-Level Radioactive Waste Policy *122 Amendments Act, 42 U.S.C. § 2021b et seq., which required the states by the end of 1992 to dispose of their domestically generated radioactive waste either in-state or through compacts with other states. In order to comply with the federal requirements, Connecticut entered into a regional compact and enacted legislation directing the Service to locate a disposal facility within the state. See Conn. Gen.Stat. § 22a-163c (1995).
The Service developed a plan which first required it to locate sites that were likely to be suitable. Of these, the Service would then identify those sites that would actually be suitable. The list of potential sites would be winnowed to eight, with the Service’s Board of Directors selecting three of the eight as finalists. Once three finalists were identified, on-site examinations would be conducted and one site would be selected as the preferred site. The preferred site would then be monitored for at least twelve months, in accordance with federal Nuclear Regulatory Commission (“NRC”) regulations.
See Santini v. Conn. Hazardous Waste Mgmt. Serv.,
On June 10, 1991, after secret deliberations, the Service announced that it had identified three sites. (The Service later identified five other back-up sites.) Two were located in Ellington, and the third was located in a neighboring town. One of the Ellington sites included the undeveloped portion of Santini’s Ellridge Estates and the entirety of his Pinney Street property. Santini did not know, prior to the Service’s June 10 announcement, that his property was under consideration. On June 30, 1991, the three potential sites, including Santini’s property, were depicted in the Hartford Courant below the international symbol for radioactivity and the headline, “Nuclear waste: Where should it go?” The Hartford Courant, June 30, 1991 at H5. In late 1991, the Service eliminated one of the three sites from consideration, leaving Santini’s property as one of two finalists.
After vocal public opposition in and around Ellington to the Service’s siting plan, the Connecticut legislature passed, and the Governor signed into law, Public Act 92^45, which directed the Service to develop a new plan for locating a disposal facility. Public Act 92-45, which took effect May 5, 1992, effectively overruled the Service’s June 10, 1991 siting announcement. Ultimately, neither Santini’s property nor any other Connecticut site was selected as the preferred site, a necessary prerequisite to the state’s exercise of its eminent domain power to take private property such as Santini’s for the construction of a disposal facility. 3
Notwithstanding the enactment of Public Act 92-45, however, Santini’s property remained economically idle until mid-1993, and he continued to incur additional carrying costs, including interest on debt and property taxes, until 1994. In 1994 Santini sued the Service in Connecticut Superior Court, alleging that its June 10, 1991 siting announcement — naming his property one of three finalists — constituted a temporary taking of his property without just compensation in violation of Article I, § 11 of the Connecticut Constitution. Santini’s
*123
complaint alleged that the Service’s siting announcement had: (1) prevented him from selling the homes and lots in Ellridge Estates; (2) prevented him from completing development of Ellridge Estates and the Pinney Street property; (3) denied him any economic return on his investments in the two parcels; (4) caused him to incur additional costs and incidental damages; and (5) left him with no alternative use of his property. Santini brought only a state-law takings claim because he believed that, under the Supreme Court’s decision in
Williamson County Regional Planning Commission v. Hamilton Bank,
The Superior Court held an eight-day bench trial in early 1998. In addition to fact witnesses, Santini and the Service both presented expert appraisal testimony concerning the economic impact of the siting announcement on Santini’s property. Santini’s appraiser, Edward Heberger, testified that Santini’s damages as a result of the June 10, 1991 siting announcement were $890,000 for the Ellridge Estates property and $65,000 for the Pinney Street property, for a total loss of $955,000. Heberger’s appraisal was based on his conclusion that the siting announcement had paralyzed Santini’s construction and sales efforts for two years, a period including the eleven months that the siting designation was in effect as well as a thirteen-month “stigma period” that followed. The Service’s appraiser, William N. Kin-nard, Jr., testified that the siting announcement had diminished the value of the Ellridge Estates property by $185,000 and the Pinney Street property by $30,000, for a total loss of $215,000.
Following trial, the Superior Court found that, although Santini had suffered an economic loss as a result of the siting announcement, the announcement “was part of the state’s planning process,” and “[s]uch planning is not actionable.”
Santini v. Conn. Hazardous Waste Mgmt. Serv.,
No. CV 94 0538646S,
Santini appealed to the Appellate Court of Connecticut, but before that court could act the Supreme Court of Connecticut transferred the case to itself.
Santini,
Following his loss in state court, Santini sued the Service in the District Court, alleging a takings claim under the Fifth and Fourteenth Amendments to the United States Constitution and 42 U.S.C. § 1983. The Service moved to dismiss the complaint and for summary judgment, and Santini also moved for summary judgment. The District Court dismissed the complaint for lack of subject matter jurisdiction under the Rooker-Feldman doctrine, concluding that Santini’s federal takings claim was inextricably intertwined with the judgment of the Connecticut Supreme Court dismissing his state-law takings claim. The court also noted that, even if Rooker-Feldman did not apply, it would grant the Service’s motion for summary judgment on the basis of collateral estoppel and on the merits of Santini’s takings claim. The court concluded that collateral estoppel barred Santini’s federal takings claim because “the issue necessary to the Connecticut Supreme Court’s decision — the extent or finality of the defendant’s action — is identical to [the] consideration required for the instant federal takings claim.” (Ruling on Mot. to Dismiss and Cross-Motions for Summ. J., Aug. 27, 2002, at 13.) The District Court also noted that the Service was entitled to summary judgment because it had not made a final decision as required by Williamson County and because the selection of Santini’s property as one of three finalists “left open the possibility that [Santini’s] property would not ultimately be selected as the radioactive disposal site.” (Id. at 15.) This appeal followed.
DISCUSSION
The Service defends the judgment of the District Court on three grounds. It argues that: (1) Santini’s takings claim is not ripe because the Service did not make a final decision with respect to his property; (2) the District Court properly concluded that it lacked jurisdiction under
Rooker-Feldman;
and (3) Santini’s takings claim is barred by res judicata and collateral estoppel. We review
de novo
the decision of the District Court, which granted the Service’s motions to dismiss and for summary judgment and denied Santini’s motion for summary judgment.
See, e.g., Manning v. Utils. Mut. Ins. Co.,
I. Ripeness
In
Williamson County,
the Supreme Court established a two-pronged test for determining whether a Fifth Amendment takings claim is ripe. “The first prong requires the government entity charged with enforcing the regulations at issue to have rendered a ‘final decision,’ ” and “[t]he second prong requires the plaintiff to have sought compensation if the state provides a ‘reasonable, certain and adequate provision for obtaining compensation.’ ”
Southview Assocs., Ltd. v. Bongartz,
Under the first
Williamson County
prong, a takings claim is not ripe until the appropriate government entity has reached a final decision regarding the property at issue.
Williamson County,
In any event, the Service misconstrues the ripeness inquiry in two ways. First, it erroneously assumes that, under
Williamson County,
the particular governmental decision of which a takings plaintiff complains' — here, the siting announcement — must itself constitute a final decision. That is not the case. Rather, the first prong of
Williamson County
requires only that the government entity
have rendered
a final decision.
See Williamson County,
II. Rooker-Feldman, Res Judicata, and Collateral Estoppel
The Service argues that, as a result of the Connecticut Supreme Court’s judgment in its favor on Santini’s state-law takings claim, the Rooker-Feldman doctrine deprives the District Court and this Court of subject matter jurisdiction over Santini’s Fifth Amendment takings claim and, in the event that Rooker-Feldman does not apply, res judicata and collateral estoppel bar Santini from litigating his takings claim in the federal courts. Santi-ni counters that, even if Rooker-Feldman, res judicata, and collateral estoppel would otherwise apply, the unique procedural posture of post -Williamson County takings claims requires us to carve out exceptions to the preclusion doctrines. Before deciding whether to create the exceptions that Santini requests, however, we must determine whether any of the three preclusion doctrines applies.
The essence of the
Rooker-Feldman
doctrine “is that inferior federal courts have no subject matter jurisdiction over cases that effectively seek review of judgments of state courts and that federal review, if any, can occur only by way of a certiorari petition to the Supreme Court.”
Moccio v. N.Y. State Office of Court Admin,
Santini’s Fifth Amendment takings claim was not litigated in the Connecticut state courts, where Santini asserted only a state-law takings claim. In order for
Rooker-Feldman
and res judicata to apply, then, Santini must have had the opportunity to litigate his federal takings claim in the state court action. Both federal and Connecticut law make clear that Santini did not have this opportunity. First, according to Santini, the only reason he brought a state-law takings claim before pursuing a federal claim is because he believed that
Williamson County
required him to do so. The Supreme Court held in
Williamson County
that, “because the Fifth Amendment proscribes takings
without just compensation,”
a takings claim is not ripe until the property owner has sought compensation through the procedures that the state provides.
Williamson County,
Applying
Williamson County,
we held in
Southview Associates,
Whether to apply collateral estoppel is a more difficult question. Collateral estoppel differs from
Rooker-Feldman
and res judicata in at least one significant respect. Collateral estoppel may preclude the relitigation of an issue that was actually litigated in a previous action, even if the claim in which the issue arises in the subsequent action was not brought and could not have been brought in the previous action whose judgment gives rise to the estoppel.
See, e.g., Gladysz v. Planning & Zoning Comm’n of Town of Plainville,
Ordinarily, collateral estoppel would apply if (1) an issue that is an essential element of Santini’s Fifth Amendment takings claim was actually litigated in the state court action; and (2) the Connecticut Supreme Court “made a determination that was necessary to its judgment with respect to that issue.”
R & R Pool & Patio, Inc. v. Zoning Bd. of Appeals of Town of Ridgefield,
The requirement of
Williamson County
that a property owner must pursue compensation through available state procedures, such as a state-law inverse condemnation action, before bringing a Fifth Amendment takings claim has created a Catch-22 for takings plaintiffs. Under
Williamson County,
a plaintiff may not bring a Fifth Amendment takings claim without first having unsuccessfully pursued a state-law takings claim. Under traditional notions of collateral estoppel, however, the state court’s adverse judgment will often preclude the plaintiffs subsequent Fifth Amendment takings claim.
See, e.g., Dodd v. Hood River County,
Although we are not prepared to declare res judicata and collateral estoppel wholly inapplicable to takings claims, we part ways with most of our sister circuits in favor of a middle ground. In
England v. Louisiana State Board of Medical Examiners,
Concerned that litigants would otherwise be deprived of the opportunity to litigate their federal claims in federal court, the
England
Court created a mechanism whereby state-court litigants could reserve their federal claims and deprive the state court’s judgment of preclusive effect in federal court. The Court stated, “There are fundamental objections to any conclusion that a litigant who has properly invoked the jurisdiction of a Federal District Court to consider federal constitutional claims can be compelled, without his consent and through no fault of his own, to accept instead a state court’s determination of those claims.”
Id.
at 415,
Admittedly, the procedural posture of this case differs somewhat from that of
England,
as Santini filed a complaint in state court first and, therefore, there was no occasion for a federal court to abstain. This distinction, however, is not a meaningful one. A though Santini initiated his action in state court, he was not in state court voluntarily.
See Fields,
*130 While we have not previously held that parties may use the England reservation procedure in cases that did not properly originate in federal court, we deem it appropriate to permit parties like Santini, who litigate state-law takings claims in state court involuntarily, to reserve their federal takings claims for determination by a federal court. It would be both ironic and unfair if the very procedure that the Supreme Court required Santini to follow before bringing a Fifth Amendment takings claim — a state-court inverse condemnation action — also precluded Santini from ever bringing a Fifth Amendment takings claim. We do not believe that the Supreme Court intended in Williamson County to deprive all property owners in states whose takings jurisprudence generally follows federal law (ie., those to whom collateral estoppel would apply) of the opportunity to bring Fifth Amendment takings claims in federal court. Thus, in permitting state-court litigants to reserve their federal takings claims for determination in subsequent federal-court actions, we decline to interpret Williamson County in such a way as to deprive a large class of prospective plaintiffs of federal forums for their federal takings claims. 7
Future takings plaintiffs will still have to comply with the
Williamson County
requirement that they pursue available inverse condemnation actions under state law before bringing federal takings claims. In doing so, however, such parties may explicitly reserve their federal takings claims, making clear to the state court and adverse parties that they intend to bring a federal takings claim in federal court once the litigation of the state-law claim has been completed. This
“Santini
reservation” will mean that the state court’s judgment on the state-law claim would not have preclusive effect in the subsequent federal action. Although San-tini did not make such a reservation in Connecticut state court, we apply the reservation requirement prospectively only, and we deem Santini, who neither litigated his federal claim in state court nor sought to do so, to have reserved his federal claim.
See England,
III. Summary Judgment
The fact that Santini’s takings claim is based on nothing more than the Service’s 1991 siting announcement — perhaps the prototypical precondemnation governmental activity — dooms the claim on its merits, as the Supreme Court has explicitly held that precondemnation activities do not constitute takings. The Court has stated:
Appellants also claim that the city’s pre-condemnation activities constitute a tak *131 ing. The State Supreme Court correctly-rejected the contention that the municipality’s good-faith planning activities, which did not result in successful prosecution of an eminent domain claim, so burdened the appellants’ enjoyment of their property as to constitute a taking. Even if the appellants’ ability to sell their property was limited during the pendency of the condemnation proceeding, the appellants were free to sell or develop their property when the proceedings ended. Mere fluctuations in value during the process of governmental decisionmaking, absent extraordinary delay, are incidents of ownership. They cannot be considered as a taking in the constitutional sense.
Agins v. City of Tiburon,
There is no doubt that the siting announcement constitutes “preliminary activity” as that term is used in First English, as the announcement was but one step of many that the state had to pursue before it could condemn Santini’s property. The Service never conducted the requisite on-site examination of Santini’s property, never selected it as the preferred site, did not monitor it for twelve months as required by NRC regulations, and did not obtain the necessary permits from the NRC, the Connecticut Department of Environmental Protection, and the Connecticut siting council.
Despite
Agins, Danforth,
and
First English,
Santini argues that the siting announcement constitutes a taking under
Lucas v. South Carolina Coastal Council,
*132
Nor can Santini succeed under
Penn Central.
First, to the extent there is any tension between
Penn Central
and
Agins,
we note that
Agins,
which was decided two years after
Penn Central,
held that pre-condemnation activity that restricts a landowner’s ability to sell or develop property or causes a diminution in its value does not constitute a taking.
Agins,
We are not unmindful of the economic impact that the siting announcement obviously had on Santini’s efforts to develop and sell his property. Unfortunately for Santini, however, this impact does not necessarily mean that the governmental action of which he complains constitutes a taking. The Court recognized in
Penn Central
that “in a wide variety of contexts, ... government may execute laws or programs that adversely affect recognized economic values.”
Penn Central,
Our decision also makes for sound public policy. As the Connecticut Supreme Court noted, “if the government were to be considered as having accomplished a compensable taking as a result of mere planning that, because of its publicity, harmed the value of property, public planning would be discouraged, and governmental secrecy in the planning process would be encouraged.”
Santini v. Conn. Hazardous Waste Mgmt. Serv.,
CONCLUSION
For these reasons, we affirm the judgment of the District Court.
Notes
. The Fifth Amendment provides, in part, "nor shall private property be taken for public use, without just compensation.” U.S. Const, amend. V. The takings clause of the Fifth Amendment is made applicable to the states through the Fourteenth Amendment.
See,
e.g.,
Dolan v. City of Tigard,
.
See Rooker v. Fidelity Trust Co.,
. Even if Santini’s property had been designated the preferred site, it still would have had to clear a number of regulatory hurdles before becoming the location of the waste disposal facility. For example, permits from the NRC, the Connecticut Department of Environmental Protection, and the Connecticut siting council, as well as eminent domain proceedings, see Conn. Gen.Stat. § 22a-163w(b), (c) (1995), would have been required.
. "Inverse condemnation should be distinguished from eminent domain. Eminent domain refers to a legal proceeding in which a government asserts its authority to condemn property. Inverse condemnation is a shorthand description of the manner in which a landowner recovers just compensation for a taking of his property when condemnation proceedings have not been instituted.”
Agins v. City of Tiburon,
. We take no position on whether Santini’s claim would have been ripe before the state decided not to acquire his properly. That is, the siting announcement itself might have constituted a final decision under Williamson County, as Santini argues, but we need not decide that here, because the state’s ultimate decision not to acquire Santini’s property was undeniably final.
. In support of Santini, the
amici
urge us to hold that the second prong of
Williamson County
requires only that plaintiffs pursue just compensation through state administrative proceedings, not through state-court inverse condemnation actions. For two independent reasons, however, this argument does not avail Santini. First, we are bound by
Williamson County
and
Southview Associates,
both of which require takings plaintiffs to pursue state-law inverse condemnation actions before bringing federal takings claims. We decline
amici's
invitation to find that the Supreme Court overruled
Williamson County sub silentio
in
City of Chicago v. International College of Surgeons, 522
U.S. 156,
. We recognize that, unlike Connecticut, other states may permit property owners to bring state and federal takings claims simultaneously. Plaintiffs who pursue inverse condemnation actions in those states in order to comply with Williamson County also may reserve their federal claims for subsequent federal court adjudication. This result is consistent with England, in which the plaintiffs were permitted to raise their federal claims anew in federal court even though they had already litigated them in state court.
