SUPREME COURT OF THE UNITED STATES

TAHOE-SIERRA PRESERVATION COUNCIL, INC., et al. v.
TAHOE REGIONAL PLANNING AGENCY et al.

CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT

No. 00-1167. Argued January 7, 2002-Decided April 23, 2002

Respondent Tahoe Regional Planning Agency (TRPA) imposed two moratoria, totaling 32 months, on development in the Lake Tahoe Basin while formulating a comprehensive land-use plan for the area. Petitioners, real estate owners affected by the moratoria and an association representing such owners, filed parallel suits, later consolidated, claiming that TRPA's actions constituted a taking of their property without just compensation. The District Court found that TRPA had not effected a "partial taking" under the analysis set out in Penn Central Transp. Co. v. New York City, 438 U.S. 104; however, it concluded that the moratoria did constitute a taking under the categorical rule announced in Lucas v. South Carolina Coastal Council, 505 U.S. 1003, because TRPA temporarily deprived petitioners of all economically viable use of their land. On appeal, TRPA successfully challenged the District Court's takings determination. Finding that the only question in this facial challenge was whether Lucas' rule applied, the Ninth Circuit held that because the regulations had only a temporary impact on petitioners' fee interest, no categorical taking had occurred; that Lucas applied to the relatively rare case in which a regulation permanently denies all productive use of an entire parcel, whereas the moratoria involved only a temporal slice of the fee interest; and that First English Evangelical Lutheran Church of Glendale v. County of Los Angeles, 482 U.S. 304, concerned the question whether compensation is an appropriate remedy for a temporary taking, not whether or when such a taking has occurred. The court also concluded that Penn Central's ad hoc balancing approach was the proper framework for analyzing whether a taking had occurred, but that petitioners had not challenged the District Court's conclusion that they could not make out a claim under Penn Central's factors.

Held: The moratoria ordered by TRPA are not per se takings of property requiring compensation under the Takings Clause. Pp. 16-39.

(a) Although this Court's physical takings jurisprudence, for the most part, involves the straightforward application of per se rules, its regulatory takings jurisprudence is characterized by "essentially ad hoc, factual inquiries," Penn Central, 438 U.S., at 124, designed to allow "careful examination and weighing of all the relevant circumstances," Palazzolo v. Rhode Island, 533 U.S. 606, 636 (O'Connor, J., concurring). The longstanding distinction between physical and regulatory takings makes it inappropriate to treat precedent from one as controlling on the other. Petitioners rely on First English and Lucas-both regulatory takings cases-to argue for a categorical rule that whenever the government imposes a deprivation of all economically viable use of property, no matter how brief, it effects a taking. In First English, 482 U.S., at 315, 318, 321, the Court addressed the separate remedial question of how compensation is measured once a regulatory taking is established, but not the different and prior question whether the temporary regulation was in fact a taking. To the extent that the Court referenced that antecedent question, it recognized that a regulation temporarily denying an owner all use of her property might not constitute a taking if the denial was part of the State's authority to enact safety regulations, or if it were one of the normal delays in obtaining building permits, changes in zoning ordinances, variances, and the like. Thus, First English did not approve, and implicitly rejected, petitioners' categorical approach. Nor is Lucas dispositive of the question presented. Its categorical rule-requiring compensation when a regulation permanently deprives an owner of "all economically beneficial uses" of his land, 505 U.S., at 1019-does not answer the question whether a regulation prohibiting any economic use of land for 32 months must be compensated. Petitioners attempt to bring this case under the rule in Lucas by focusing exclusively on the property during the moratoria is unavailing. This Court has consistently rejected such an approach to the "denominator" question. See, e.g., Keystone Bituminous Coal Assn. v. DeBenedictis, 480 U.S. 470, 497. To sever a 32-month segment from the remainder of each fee simple estate and then ask whether that segment has been taken in its entirety would ignore Penn Central's admonition to focus on "the parcel as a whole," 438 U.S., at 130-131. Both dimensions of a real property interest-the metes and bounds describing its geographic dimensions and the term of years describing its temporal aspect-must be considered when viewing the interest in its entirety. A permanent deprivation of all use is a taking of the parcel as a whole, but a temporary restriction causing a diminution in value is not, for the property will recover value when the prohibition is lifted. Lucas was carved out for the "extraordinary case" in which a regulation permanently deprives property of all use; the default rule remains that a fact specific inquiry is required in the regulatory taking context. Nevertheless, the Court will consider petitioners' argument that the interest in protecting property owners from bearing public burdens "which, in all fairness and justice, should be borne by the public as a whole," Armstrong v. United States, 364 U.S. 40, 49, justifies creating a new categorical rule. Pp. 17-29.

(b) "Fairness and justice" will not be better served by a categorical rule that any deprivation of all economic use, no matter how brief, constitutes a compensable taking. That rule would apply to numerous normal delays in obtaining, e.g., building permits, and would require changes in practices that have long been considered permissible exercises of the police power. Such an important change in the law should be the product of legislative rulemaking not adjudication. More importantly, for the reasons set out in Justice O'Connor's concurring opinion in Palazzolo, 533 U.S., at 636, the better approach to a temporary regulatory taking claim requires careful examination and weighing of all the relevant circumstances-only one of which is the length of the delay. A narrower rule excluding normal delays in processing permits, or covering only delays of more than a year, would have a less severe impact on prevailing practices, but would still impose serious constraints on the planning process. Moratoria are an essential tool of successful development. The interest in informed decisionmaking counsels against adopting a per se rule that would treat such interim measures as takings regardless of the planners' good faith, the landowners' reasonable expectations, or the moratorium's actual impact on property values. The financial constraints of compensating property owners during a moratorium may force officials to rush through the planning process or abandon the practice altogether. And the interest in protecting the decisional process is even stronger when an agency is developing a regional plan than when it is considering a permit for a single parcel. Here, TRPA obtained the benefit of comments and criticisms from interested parties during its deliberations, but a categorical rule tied to the deliberations' length would likely create added pressure on decisionmakers to quickly resolve land-use questions, disadvantaging landowners and interest groups less organized or familiar with the planning process. Moreover, with a temporary development ban, there is less risk that individual landowners will be singled out to bear a special burden that should be shared by the public as a whole. It may be true that a moratorium lasting more than one year should be viewed with special skepticism, but the District Court found that the instant delay was not unreasonable. The restriction's duration is one factor for a court to consider in appraising regulatory takings claims, but with respect to that factor, the temptation to adopt per se rules in either direction must be resisted. Pp. 28-39.

SUPREME COURT OF THE UNITED STATES

No. 00-1167

TAHOE-SIERRA PRESERVATION COUNCIL, INC.,
et al., PETITIONERS v. TAHOE REGIONAL
PLANNING AGENCY et al.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE NINTH CIRCUIT
[April 23, 2002]

Justice Stevens delivered the opinion of the Court.

The question presented is whether a moratorium on development imposed during the process of devising a comprehensive land-use plan constitutes a per se taking of property requiring compensation under the Takings Clause of the United States Constitution.1 This case actually involves two moratoria ordered by respondent Tahoe Regional Planning Agency (TRPA) to maintain the status quo while studying the impact of development on Lake Tahoe and designing a strategy for environmentally sound growth. The first, Ordinance 81-5, was effective from August 24, 1981, until August 26, 1983, whereas the second more restrictive Resolution 83-21 was in effect from August 27, 1983, until April 25, 1984. As a result of these two directives, virtually all development on a substantial portion of the property subject to TRPA's jurisdiction was prohibited for a period of 32 months. Although the question we decide relates only to that 32-month period, a brief description of the events leading up to the moratoria and a comment on the two permanent plans that TRPA adopted thereafter will clarify the narrow scope of our holding.

The relevant facts are undisputed. The Court of Appeals, while reversing the District Court on a question of law, accepted all of its findings of fact, and no party challenges those findings. All agree that Lake Tahoe is "uniquely beautiful," 34 F. Supp. 2d 1226, 1230 (Nev. 1999), that President Clinton was right to call it a " 'national treasure that must be protected and preserved,' " ibid., and that Mark Twain aptly described the clarity of its waters as " 'not merely transparent, but dazzlingly, brilliantly so,' " ibid. (emphasis added) (quoting M. Twain, Roughing It 174-175 (1872)).

Lake Tahoe's exceptional clarity is attributed to the absence of algae that obscures the waters of most other lakes. Historically, the lack of nitrogen and phosphorous, which nourish the growth of algae, has ensured the transparency of its waters.2 Unfortunately, the lake's pristine state has deteriorated rapidly over the past 40 years; increased land development in the Lake Tahoe Basin (Basin) has threatened the " 'noble sheet of blue water' " beloved by Twain and countless others. 34 F. Supp., at 1230. As the District Court found, "[d]ramatic decreases in clarity first began to be noted in the 1950's/early 1960's, shortly after development at the lake began in earnest." Id., at 1231. The lake's unsurpassed beauty, it seems, is the wellspring of its undoing.

The upsurge of development in the area has caused "increased nutrient loading of the lake largely because of the increase in impervious coverage of land in the Basin resulting from that development." Ibid.

"Impervious coverage-such as asphalt, concrete, buildings, and even packed dirt-prevents precipitation from being absorbed by the soil. Instead, the water is gathered and concentrated by such coverage. Larger amounts of water flowing off a driveway or a roof have more erosive force than scattered raindrops falling over a dispersed area-especially one covered with indigenous vegetation, which softens the impact of the raindrops themselves." Ibid.
Given this trend, the District Court predicted that "unless the process is stopped, the lake will lose its clarity and its trademark blue color, becoming green and opaque for eternity."3

Those areas in the Basin that have steeper slopes produce more runoff; therefore, they are usually considered "high hazard" lands. Moreover, certain areas near streams or wetlands known as "Stream Environment Zones" (SEZs) are especially vulnerable to the impact of development because, in their natural state, they act as filters for much of the debris that runoff carries. Because "[t]he most obvious response to this problem … is to restrict development around the lake-especially in SEZ lands, as well as in areas already naturally prone to runoff," id., at 1232, conservation efforts have focused on controlling growth in these high hazard areas.

In the 1960's, when the problems associated with the burgeoning development began to receive significant attention, jurisdiction over the Basin, which occupies 501 square miles, was shared by the States of California and Nevada, five counties, several municipalities, and the Forest Service of the Federal Government. In 1968, the legislatures of the two States adopted the Tahoe Regional Planning Compact, see 1968 Cal. Stats., ch. 998, p. 1900, §1; 1968 Nev. Stats. 4, which Congress approved in 1969, Pub. L. 91-148, 83 Stat. 360. The compact set goals for the protection and preservation of the lake and created TRPA as the agency assigned "to coordinate and regulate development in the Basin and to conserve its natural resources." Lake Country Estates, Inc. v. Tahoe Regional Planning Agency, 440 U.S. 391, 394 (1979).

Pursuant to the compact, in 1972 TRPA adopted a Land Use Ordinance that divided the land in the Basin into seven "land capability districts," based largely on steepness but also taking into consideration other factors affecting runoff. Each district was assigned a "land coverage coefficient-a recommended limit on the percentage of such land that could be covered by impervious surface." Those limits ranged from 1% for districts 1 and 2 to 30% for districts 6 and 7. Land in districts 1, 2, and 3 is characterized as "high hazard" or "sensitive," while land in districts 4, 5, 6, and 7 is "low hazard" or "non-sensitive." The SEZ lands, though often treated as a separate category, were actually a subcategory of district 1. 34 F. Supp. 2d, at 1232.

Unfortunately, the 1972 ordinance allowed numerous exceptions and did not significantly limit the construction of new residential housing. California became so dissatisfied with TRPA that it withdrew its financial support and unilaterally imposed stricter regulations on the part of the Basin located in California. Eventually the two States, with the approval of Congress and the President, adopted an extensive amendment to the compact that became effective on December 19, 1980. Pub. L. 96-551, 94 Stat. 3233; Cal. Govt Code Ann. §66801 (West Supp. 2002); Nev. Rev. Stat. §277.200 (1980).

The 1980 Tahoe Regional Planning Compact (Compact) redefined the structure, functions, and voting procedures of TRPA, App. 37, 94 Stat. 3235-3238; 34 F. Supp. 2d, at 1233, and directed it to develop regional "environmental threshold carrying capacities"-a term that embraced "standards for air quality, water quality, soil conservation, vegetation preservation and noise." 94 Stat. 3235, 3239. The Compact provided that TRPA "shall adopt" those standards within 18 months, and that "[w]ithin 1 year after" their adoption (i.e., by June 19, 1983), it "shall" adopt an amended regional plan that achieves and maintains those carrying capacities. Id., at 3240. The Compact also contained a finding by the Legislatures of California and Nevada "that in order to make effective the regional plan as revised by [TRPA], it is necessary to halt temporarily works of development in the region which might otherwise absorb the entire capability of the region for further development or direct it out of harmony with the ultimate plan." Id., at 3243. Accordingly, for the period prior to the adoption of the final plan ("or until May 1, 1983, whichever is earlier"), the Compact itself prohibited the development of new subdivisions, condominiums, and apartment buildings, and also prohibited each city and county in the Basin from granting any more permits in 1981, 1982, or 1983 than had been granted in 1978.4

During this period TRPA was also working on the development of a regional water quality plan to comply with the Clean Water Act, 33 U.S.C. § 1288 (1994 ed.). Despite the fact that TRPA performed these obligations in "good faith and to the best of its ability," 34 F. Supp. 2d., at 1233, after a few months it concluded that it could not meet the deadlines in the Compact. On June 25, 1981, it therefore enacted Ordinance 81-5 imposing the first of the two moratoria on development that petitioners challenge in this proceeding. The ordinance provided that it would become effective on August 24, 1981, and remain in effect pending the adoption of the permanent plan required by the Compact. App. 159, 191.

The District Court made a detailed analysis of the ordinance, noting that it might even prohibit hiking or picnicking on SEZ lands, but construed it as essentially banning any construction or other activity that involved the removal of vegetation or the creation of land coverage on all SEZ lands, as well as on class 1, 2, and 3 lands in California. 34 F. Supp. 2d, at 1233-1235. Some permits could be obtained for such construction in Nevada if certain findings were made. Id., at 1235. It is undisputed, however, that Ordinance 81-5 prohibited the construction of any new residences on SEZ lands in either State and on class 1, 2, and 3 lands in California.

Given the complexity of the task of defining "environmental threshold carrying capacities" and the division of opinion within TRPA's governing board, the District Court found that it was "unsurprising" that TRPA failed to adopt those thresholds until August 26, 1982, roughly two months after the Compact deadline. Ibid. Under a liberal reading of the Compact, TRPA then had until August 26, 1983, to adopt a new regional plan. 94 Stat. 3240. "Unfortunately, but again not surprisingly, no regional plan was in place as of that date." 34 F. Supp. 2d, at 1235. TRPA therefore adopted Resolution 83-21, "which completely suspended all project reviews and approvals, including the acceptance of new proposals," and which remained in effect until a new regional plan was adopted on April 26, 1984. Thus, Resolution 83-21 imposed an 8-month moratorium prohibiting all construction on high hazard lands in either State. In combination, Ordinance 81-5 and Resolution 83-21 effectively prohibited all construction on sensitive lands in California and on all SEZ lands in the entire Basin for 32 months, and on sensitive lands in Nevada (other than SEZ lands) for eight months. It is these two moratoria that are at issue in this case.

On the same day that the 1984 plan was adopted, the State of California filed an action seeking to enjoin its implementation on the ground that it failed to establish land-use controls sufficiently stringent to protect the Basin. Id., at 1236. The District Court entered an injunction that was upheld by the Court of Appeals and remained in effect until a completely revised plan was adopted in 1987. Both the 1984 injunction and the 1987 plan contained provisions that prohibited new construction on sensitive lands in the Basin. As the case comes to us, however, we have no occasion to consider the validity of those provisions.

Approximately two months after the adoption of the 1984 Plan, petitioners filed parallel actions against TRPA and other defendants in federal courts in Nevada and California that were ultimately consolidated for trial in the District of Nevada. The petitioners include the Tahoe Sierra Preservation Council, a nonprofit membership corporation representing about 2,000 owners of both improved and unimproved parcels of real estate in the Lake Tahoe Basin, and a class of some 400 individual owners of vacant lots located either on SEZ lands or in other parts of districts 1, 2, or 3. Those individuals purchased their properties prior to the effective date of the 1980 Compact, App. 34, primarily for the purpose of constructing "at a time of their choosing" a single-family home "to serve as a permanent, retirement or vacation residence," id., at 36. When they made those purchases, they did so with the understanding that such construction was authorized provided that "they complied with all reasonable requirements for building." Ibid.5

Petitioners' complaints gave rise to protracted litigation that has produced four opinions by the Court of Appeals for the Ninth Circuit and several published District Court opinions.6 For present purposes, however, we need only describe those courts' disposition of the claim that three actions taken by TRPA-Ordinance 81-5, Resolution 83-21, and the 1984 regional plan-constituted takings of petitioners' property without just compensation.7 Indeed, the challenge to the 1984 plan is not before us because both the District Court and the Court of Appeals held that it was the federal injunction against implementing that plan, rather than the plan itself, that caused the post-1984 injuries that petitioners allegedly suffered, and those rulings are not encompassed within our limited grant of certiorari.8 Thus, we limit our discussion to the lower courts' disposition of the claims based on the 2-year moratorium (Ordinance 81-5) and the ensuing 8-month moratorium (Resolution 83-21).

The District Court began its constitutional analysis by identifying the distinction between a direct government appropriation of property without just compensation and a government regulation that imposes such a severe restriction on the owner's use of her property that it produces "nearly the same result as a direct appropriation." 34 F. Supp. 2d, at 1238. The court noted that all of the claims in this case "are of the 'regulatory takings' variety." Id., at 1239. Citing our decision in Agins v. City of Tiburon, 447 U.S. 255 (1980), it then stated that a "regulation will constitute a taking when either: (1) it does not substantially advance a legitimate state interest; or (2) it denies the owner economically viable use of her land." 34 F. Supp. 2d, at 1239. The District Court rejected the first alternative based on its finding that "further development on high hazard lands such as [petitioners'] would lead to significant additional damage to the lake." Id., at 1240.9 With respect to the second alternative, the court first considered whether the analysis adopted in Penn Central Transp. Co. v. New York City, 438 U.S. 104 (1978), would lead to the conclusion that TRPA had effected a "partial taking," and then whether those actions had effected a "total taking."10

Emphasizing the temporary nature of the regulations, the testimony that the "average holding time of a lot in the Tahoe area between lot purchase and home construction is twenty-five years," and the failure of petitioners to offer specific evidence of harm, the District Court concluded that "consideration of the Penn Central factors clearly leads to the conclusion that there was no taking." 34 F. Supp. 2d, at 1240. In the absence of evidence regarding any of the individual plaintiffs, the court evaluated the "average" purchasers' intent and found that such purchasers "did not have reasonable, investment-backed expectations that they would be able to build single-family homes on their land within the six-year period involved in this lawsuit."11

The District Court had more difficulty with the "total taking" issue. Although it was satisfied that petitioners' property did retain some value during the moratoria,12 it found that they had been temporarily deprived of "all economically viable use of their land." Id., at 1245. The court concluded that those actions therefore constituted "categorical" takings under our decision in Lucas v. South Carolina Coastal Council, 505 U.S. 1003 (1992). It rejected TRPA's response that Ordinance 81-5 and Resolution 83-21 were "reasonable temporary planning moratoria" that should be excluded from Lucas' categorical approach. The court thought it "fairly clear" that such interim actions would not have been viewed as takings prior to our decisions in Lucas and First English Evangelical Lutheran Church of Glendale v. County of Los Angeles, 482 U.S. 304 (1987), because "[z]oning boards, cities, counties and other agencies used them all the time to 'maintain the status quo pending study and governmental decision making.' " 34 F. Supp. 2d., at 1248-1249 (quoting Williams v. Central, 907 P.2d 701, 706 (Colo. App. 1995)). After expressing uncertainty as to whether those cases required a holding that moratoria on development automatically effect takings, the court concluded that TRPA's actions did so, partly because neither the ordinance nor the resolution, even though intended to be temporary from the beginning, contained an express termination date. 34 F. Supp. 2d, at 1250-1251.13 Accordingly, it ordered TRPA to pay damages to most petitioners for the 32-month period from August 24, 1981, to April 25, 1984, and to those owning class 1, 2, or 3 property in Nevada for the 8-month period from August 27, 1983, to April 25, 1984. Id., at 1255.

Both parties appealed. TRPA successfully challenged the District Court's takings determination, and petitioners unsuccessfully challenged the dismissal of their claims based on the 1984 and 1987 plans. Petitioners did not, however, challenge the District Court's findings or conclusions concerning its application of Penn Central. With respect to the two moratoria, the Ninth Circuit noted that petitioners had expressly disavowed an argument "that the regulations constitute a taking under the ad hoc balancing approach described in Penn Central" and that they did not "dispute that the restrictions imposed on their properties are appropriate means of securing the purpose set forth in the Compact."14 Accordingly, the only question before the court was "whether the rule set forth in Lucas applies-that is, whether a categorical taking occurred because Ordinance 81-5 and Resolution 83-21 denied the plaintiffs' 'all economically beneficial or productive use of land.' " 216 F.3d 764, 773 (2000). Moreover, because petitioners brought only a facial challenge, the narrow inquiry before the Court of Appeals was whether the mere enactment of the regulations constituted a taking.

Contrary to the District Court, the Court of Appeals held that because the regulations had only a temporary impact on petitioners' fee interest in the properties, no categorical taking had occurred. It reasoned:

"Property interests may have many different dimensions. For example, the dimensions of a property interest may include a physical dimension (which describes the size and shape of the property in question), a functional dimension (which describes the extent to which an owner may use or dispose of the property in question), and a temporal dimension (which describes the duration of the property interest). At base, the plaintiffs' argument is that we should conceptually sever each plaintiff's fee interest into discrete segments in at least one of these dimensions-the temporal one-and treat each of those segments as separate and distinct property interests for purposes of takings analysis. Under this theory, they argue that there was a categorical taking of one of those temporal segments." Id., at 774.

Putting to one side "cases of physical invasion or occupation," ibid., the court read our cases involving regulatory taking claims to focus on the impact of a regulation on the parcel as a whole. In its view a "planning regulation that prevents the development of a parcel for a temporary period of time is conceptually no different than a land-use restriction that permanently denies all use on a discrete portion of property, or that permanently restricts a type of use across all of the parcel." Id., at 776. In each situation, a regulation that affects only a portion of the parcel-whether limited by time, use, or space-does not deprive the owner of all economically beneficial use.15

The Court of Appeals distinguished Lucas as applying to the " 'relatively rare' " case in which a regulation denies all productive use of an entire parcel, whereas the moratoria involve only a "temporal 'slice' " of the fee interest and a form of regulation that is widespread and well established. 216 F.3d, at 773-774. It also rejected petitioners' argument that our decision in First English was controlling. According to the Court of Appeals, First English concerned the question whether compensation is an appropriate remedy for a temporary taking and not whether or when such a taking has occurred. 216 F.3d, at 778. Faced squarely with the question whether a taking had occurred, the court held that Penn Central was the appropriate framework for analysis. Petitioners, however, had failed to challenge the District Court's conclusion that they could not make out a taking claim under the Penn Central
factors.

Over the dissent of five judges, the Ninth Circuit denied a petition for rehearing en banc. 228 F.3d 998 (2000). In the dissenters' opinion, the panel's holding was not faithful to this Court's decisions in First English and Lucas, nor to Justice Holmes admonition in Pennsylvania Coal Co. v. Mahon, 260 U.S. 393, 416 (1922), that " 'a strong public desire to improve the public condition is not enough to warrant achieving the desire by a shorter cut than the constitutional way of paying for the change.' " 228 F.3d, at 1003. Because of the importance of the case, we granted certiorari limited to the question stated at the beginning of this opinion. 533 U.S. 948 (2001). We now affirm.

Petitioners make only a facial attack on Ordinance 81-5 and Resolution 83-21. They contend that the mere enactment of a temporary regulation that, while in effect, denies a property owner all viable economic use of her property gives rise to an unqualified constitutional obligation to compensate her for the value of its use during that period. Hence, they "face an uphill battle," Keystone Bituminous Coal Assn. v. DeBenedictis, 480 U.S. 470, 495 (1987), that is made especially steep by their desire for a categorical rule requiring compensation whenever the government imposes such a moratorium on development. Under their proposed rule, there is no need to evaluate the landowners' investment-backed expectations, the actual impact of the regulation on any individual, the importance of the public interest served by the regulation, or the reasons for imposing the temporary restriction. For petitioners, it is enough that a regulation imposes a temporary deprivation-no matter how brief-of all economically viable use to trigger a per se rule that a taking has occurred. Petitioners assert that our opinions in First English and Lucas have already endorsed their view, and that it is a logical application of the principle that the Takings Clause was "designed to bar Government from forcing some people alone to bear burdens which, in all fairness and justice, should be borne by the public as a whole." Armstrong v. United States, 364 U.S. 40, 49 (1960).

We shall first explain why our cases do not support their proposed categorical rule-indeed, fairly read, they implicitly reject it. Next, we shall explain why the Armstrong principle requires rejection of that rule as well as the less extreme position advanced by petitioners at oral argument. In our view the answer to the abstract question whether a temporary moratorium effects a taking is neither "yes, always" nor "no, never"; the answer depends upon the particular circumstances of the case.16 Resisting "[t]he temptation to adopt what amount to per se rules in either direction," Palazzolo v. Rhode Island, 533 U.S. 606, 636 (2001) (O'Connor, J., concurring), we conclude that the circumstances in this case are best analyzed within the Penn Central framework.

The text of the Fifth Amendment itself provides a basis for drawing a distinction between physical takings and regulatory takings. Its plain language requires the payment of compensation whenever the government acquires private property for a public purpose, whether the acquisition is the result of a condemnation proceeding or a physical appropriation. But the Constitution contains no comparable reference to regulations that prohibit a property owner from making certain uses of her private property.17 Our jurisprudence involving condemnations and physical takings is as old as the Republic and, for the most part, involves the straightforward application of per se rules. Our regulatory takings jurisprudence, in contrast, is of more recent vintage and is characterized by "essentially ad hoc, factual inquiries," Penn Central, 438 U.S., at 124, designed to allow "careful examination and weighing of all the relevant circumstances." Palazzolo, 533 U.S., at 636 (O'Connor, J., concurring).

When the government physically takes possession of an interest in property for some public purpose, it has a categorical duty to compensate the former owner, United States v. Pewee Coal Co., 341 U.S. 114, 115 (1951), regardless of whether the interest that is taken constitutes an entire parcel or merely a part thereof. Thus, compensation is mandated when a leasehold is taken and the government occupies the property for its own purposes, even though that use is temporary. United States v. General Motors Corp., 323 U.S. 373 (1945), United States v. Petty Motor Co., 327 U.S. 372 (1946). Similarly, when the government appropriates part of a rooftop in order to provide cable TV access for apartment tenants, Loretto v. Teleprompter Manhattan CATV Corp., 458 U.S. 419 (1982); or when its planes use private airspace to approach a government airport, United States v. Causby, 328 U.S. 256 (1946), it is required to pay for that share no matter how small. But a government regulation that merely prohibits landlords from evicting tenants unwilling to pay a higher rent, Block v. Hirsh, 256 U.S. 135 (1921); that bans certain private uses of a portion of an owner's property, Village of Euclid v. Ambler Realty Co., 272 U.S. 365 (1926); Keystone Bituminous Coal Assn. v. DeBenedictis, 480 U.S. 470 (1987); or that forbids the private use of certain airspace, Penn Central Transp. Co. v. New York City, 438 U.S. 104 (1978), does not constitute a categorical taking. "The first category of cases requires courts to apply a clear rule; the second necessarily entails complex factual assessments of the purposes and economic effects of government actions." Yee v. Escondido, 503 U.S. 519, 523 (1992). See also Loretto, 458 U.S., at 440; Keystone, 480 U.S., at 489, n. 18.

This longstanding distinction between acquisitions of property for public use, on the one hand, and regulations prohibiting private uses, on the other, makes it inappropriate to treat cases involving physical takings as controlling precedents for the evaluation of a claim that there has been a "regulatory taking,"18 and vice versa. For the same reason that we do not ask whether a physical appropriation advances a substantial government interest or whether it deprives the owner of all economically valuable use, we do not apply our precedent from the physical takings context to regulatory takings claims. Land-use regulations are ubiquitous and most of them impact property values in some tangential way-often in completely unanticipated ways. Treating them all as per se takings would transform government regulation into a luxury few governments could afford. By contrast, physical appropriations are relatively rare, easily identified, and usually represent a greater affront to individual property rights.19 "This case does not present the 'classi[c] taking' in which the government directly appropriates private property for its own use," Eastern Enterprises v. Apfel, 524 U.S. 498, 522 (1998); instead the interference with property rights "arises from some public program adjusting the benefits and burdens of economic life to promote the common good," Penn Central, 438 U.S., at 124.

Perhaps recognizing this fundamental distinction, petitioners wisely do not place all their emphasis on analogies to physical takings cases. Instead, they rely principally on our decision in Lucas v. South Carolina Coastal Council, 505 U.S. 1003 (1992)-a regulatory takings case that, nevertheless, applied a categorical rule-to argue that the Penn Central framework is inapplicable here. A brief review of some of the cases that led to our decision in Lucas, however, will help to explain why the holding in that case does not answer the question presented here.

As we noted in Lucas, it was Justice Holmes' opinion in Pennsylvania Coal Co. v. Mahon, 260 U.S. 393 (1922),20 that gave birth to our regulatory takings jurisprudence.21 In subsequent opinions we have repeatedly and consistently endorsed Holmes' observation that "if regulation goes too far it will be recognized as a taking." Id., at 415. Justice Holmes did not provide a standard for determining when a regulation goes "too far," but he did reject the view expressed in Justice Brandeis' dissent that there could not be a taking because the property remained in the possession of the owner and had not been appropriated or used by the public.22 After Mahon, neither a physical appropriation nor a public use has ever been a necessary component of a "regulatory taking."

In the decades following that decision, we have "generally eschewed" any set formula for determining how far is too far, choosing instead to engage in " 'essentially ad hoc, factual inquiries.' " Lucas, 505 U.S., at 1015 (quoting Penn Central, 438 U.S., at 124). Indeed, we still resist the temptation to adopt per se rules in our cases involving partial regulatory takings, preferring to examine "a number of factors" rather than a simple "mathematically precise" formula.23 Justice Brennan's opinion for the Court in Penn Central did, however, make it clear that even though multiple factors are relevant in the analysis of regulatory takings claims, in such cases we must focus on "the parcel as a whole":

" ' Taking' jurisprudence does not divide a single parcel into discrete segments and attempt to determine whether rights in a particular segment have been entirely abrogated. In deciding whether a particular governmental action has effected a taking, this Court focuses rather both on the character of the action and on the nature and extent of the interference with rights in the parcel as a whole-here, the city tax block designated as the 'landmark site.' " Id., at 130-131.

This requirement that "the aggregate must be viewed in its entirety" explains why, for example, a regulation that prohibited commercial transactions in eagle feathers, but did not bar other uses or impose any physical invasion or restraint upon them, was not a taking. Andrus v. Allard, 444 U.S. 51, 66 (1979). It also clarifies why restrictions on the use of only limited portions of the parcel, such as set-back ordinances, Gorieb v. Fox, 274 U.S. 603 (1927), or a requirement that coal pillars be left in place to prevent mine subsidence, Keystone Bituminous Coal Assn. v. DeBenedictis, 480 U.S., at 498, were not considered regulatory takings. In each of these cases, we affirmed that "where an owner possesses a full 'bundle' of property rights, the destruction of one 'strand' of the bundle is not a taking." Andrus, 444 U.S., at 65-66.

While the foregoing cases considered whether particular regulations had "gone too far" and were therefore invalid, none of them addressed the separate remedial question of how compensation is measured once a regulatory taking is established. In his dissenting opinion in San Diego Gas & Elec. Co. v. San Diego, 450 U.S. 621, 636 (1981), Justice Brennan identified that question and explained how he would answer it:

"The constitutional rule I propose requires that, once a court finds that a police power regulation has effected a 'taking,' the government entity must pay just compensation for the period commencing on the date the regulation first effected the 'taking,' and ending on the date the government entity chooses to rescind or otherwise amend the regulation." Id., at 658.

Justice Brennan's proposed rule was subsequently endorsed by the Court in First English, 482 U.S., at 315, 318, 321. First English was certainly a significant decision, and nothing that we say today qualifies its holding. Nonetheless, it is important to recognize that we did not address in that case the quite different and logically prior question whether the temporary regulation at issue had in fact constituted a taking.

In First English, the Court unambiguously and repeatedly characterized the issue to be decided as a "compensation question" or a "remedial question." Id., at 311 ("The disposition of the case on these grounds isolates the remedial question for our consideration"); see also id., at 313, 318. And the Court's statement of its holding was equally unambiguous: "We merely hold that where the government's activities have already worked a taking of all use of property, no subsequent action by the government can relieve it of the duty to provide compensation for the period during which the taking was effective." Id., at 321 (emphasis added). In fact, First English expressly disavowed any ruling on the merits of the takings issue because the California courts had decided the remedial question on the assumption that a taking had been alleged. Id., at 312-313 ("We reject appellee's suggestion that … we must independently evaluate the adequacy of the complaint and resolve the takings claim on the merits before we can reach the remedial question"). After our remand, the California courts concluded that there had not been a taking, First English Evangelical Church of Glendale v. County of Los Angeles, 210 Cal. App. 3d 1353, 258 Cal. Rptr. 893 (1989), and we declined review of that decision, 493 U.S. 1056 (1990).

To the extent that the Court in First English referenced the antecedent takings question, we identified two reasons why a regulation temporarily denying an owner all use of her property might not constitute a taking. First, we recognized that "the county might avoid the conclusion that a compensable taking had occurred by establishing that the denial of all use was insulated as a part of the State's authority to enact safety regulations." 482 U.S., at 313. Second, we limited our holding "to the facts presented" and recognized "the quite different questions that would arise in the case of normal delays in obtaining building permits, changes in zoning ordinances, variances, and the like which [were] not before us." Id., at 321. Thus, our decision in First English surely did not approve, and implicitly rejected, the categorical submission that petitioners are now advocating.

Similarly, our decision in Lucas is not dispositive of the question presented. Although Lucas endorsed and applied a categorical rule, it was not the one that petitioners propose. Lucas purchased two residential lots in 1988 for $975,000. These lots were rendered "valueless" by a statute enacted two years later. The trial court found that a taking had occurred and ordered compensation of $1,232,387.50, representing the value of the fee simple estate, plus interest. As the statute read at the time of the trial, it effected a taking that "was unconditional and permanent." 505 U.S., at 1012. While the State's appeal was pending, the statute was amended to authorize exceptions that might have allowed Lucas to obtain a building permit. Despite the fact that the amendment gave the State Supreme Court the opportunity to dispose of the appeal on ripeness grounds, it resolved the merits of the permanent takings claim and reversed. Since "Lucas had no reason to proceed on a 'temporary taking' theory at trial," we decided the case on the permanent taking theory that both the trial court and the State Supreme Court had addressed. Ibid.

The categorical rule that we applied in Lucas states that compensation is required when a regulation deprives an owner of "all economically beneficial uses" of his land. Id., at 1019. Under that rule, a statute that "wholly eliminated the value" of Lucas' fee simple title clearly qualified as a taking. But our holding was limited to "the extraordinary circumstance when no productive or economically beneficial use of land is permitted." Id., at 1017. The emphasis on the word "no" in the text of the opinion was, in effect, reiterated in a footnote explaining that the categorical rule would not apply if the diminution in value were 95% instead of 100%. Id., at 1019, n. 8.24 Anything less than a "complete elimination of value," or a "total loss," the Court acknowledged, would require the kind of analysis applied in Penn Central. Lucas, 505 U.S., at 1019-1020, n. 8.25

Certainly, our holding that the permanent "obliteration of the value" of a fee simple estate constitutes a categorical taking does not answer the question whether a regulation prohibiting any economic use of land for a 32-month period has the same legal effect. Petitioners seek to bring this case under the rule announced in Lucas by arguing that we can effectively sever a 32-month segment from the remainder of each landowner's fee simple estate, and then ask whether that segment has been taken in its entirety by the moratoria. Of course, defining the property interest taken in terms of the very regulation being challenged is circular. With property so divided, every delay would become a total ban; the moratorium and the normal permit process alike would constitute categorical takings. Petitioners' "conceptual severance" argument is unavailing because it ignores Penn Central's admonition that in regulatory takings cases we must focus on "the parcel as a whole." 438 U.S., at 130-131. We have consistently rejected such an approach to the "denominator" question. See Keystone, 480 U.S., at 497. See also, Concrete Pipe & Products of Cal., Inc. v. Construction Laborers Pension Trust for Southern Cal., 508 U.S. 602, 644 (1993) ("To the extent that any portion of property is taken, that portion is always taken in its entirety; the relevant question, however, is whether the property taken is all, or only a portion of, the parcel in question"). Thus, the District Court erred when it disaggregated petitioners' property into temporal segments corresponding to the regulations at issue and then analyzed whether petitioners were deprived of all economically viable use during each period. 34 F. Supp. 2d, at 1242-1245. The starting point for the court's analysis should have been to ask whether there was a total taking of the entire parcel; if not, then Penn Central was the proper framework.26

An interest in real property is defined by the metes and bounds that describe its geographic dimensions and the term of years that describes the temporal aspect of the owner's interest. See Restatement of Property §§7-9 (1936). Both dimensions must be considered if the interest is to be viewed in its entirety. Hence, a permanent deprivation of the owner's use of the entire area is a taking of "the parcel as a whole," whereas a temporary restriction that merely causes a diminution in value is not. Logically, a fee simple estate cannot be rendered valueless by a temporary prohibition on economic use, because the property will recover value as soon as the prohibition is lifted. Cf. Agins v. City of Tiburon, 447 U.S., at 263, n. 9 ("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' ") (quoting Danforth v. United States, 308 U.S. 271, 285 (1939))).

Neither Lucas, nor First English, nor any of our other regulatory takings cases compels us to accept petitioners' categorical submission. In fact, these cases make clear that the categorical rule in Lucas was carved out for the "extraordinary case" in which a regulation permanently deprives property of all value; the default rule remains that, in the regulatory taking context, we require a more fact specific inquiry. Nevertheless, we will consider whether the interest in protecting individual property owners from bearing public burdens "which, in all fairness and justice, should be borne by the public as a whole," Armstrong v. United States, 364 U.S., at 49, justifies creating a new rule for these circumstances.27

Considerations of "fairness and justice" arguably could support the conclusion that TRPA's moratoria were takings of petitioners' property based on any of seven different theories. First, even though we have not previously done so, we might now announce a categorical rule that, in the interest of fairness and justice, compensation is required whenever government temporarily deprives an owner of all economically viable use of her property. Second, we could craft a narrower rule that would cover all temporary land-use restrictions except those "normal delays in obtaining building permits, changes in zoning ordinances, variances, and the like" which were put to one side in our opinion in First English, 482 U.S., at 321. Third, we could adopt a rule like the one suggested by an amicus supporting petitioners that would "allow a short fixed period for deliberations to take place without compensation-say maximum one year-after which the just compensation requirements" would "kick in."28 Fourth, with the benefit of hindsight, we might characterize the successive actions of TRPA as a "series of rolling moratoria" that were the functional equivalent of a permanent taking.29 Fifth, were it not for the findings of the District Court that TRPA acted diligently and in good faith, we might have concluded that the agency was stalling in order to avoid promulgating the environmental threshold carrying capacities and regional plan mandated by the 1980 Compact. Cf. Monterey v. Del Monte Dunes at Monterey, Ltd., 526 U.S. 687, 698 (1999). Sixth, apart from the District Court's finding that TRPA's actions represented a proportional response to a serious risk of harm to the lake, petitioners might have argued that the moratoria did not substantially advance a legitimate state interest, see Agins and Monterey. Finally, if petitioners had challenged the application of the moratoria to their individual parcels, instead of making a facial challenge, some of them might have prevailed under a Penn Central analysis.

As the case comes to us, however, none of the last four theories is available. The "rolling moratoria" theory was presented in the petition for certiorari, but our order granting review did not encompass that issue, 533 U.S. 948 (2001); the case was tried in the District Court and reviewed in the Court of Appeals on the theory that each of the two moratoria was a separate taking, one for a 2-year period and the other for an 8-month period. 216 F.3d, at 769. And, as we have already noted, recovery on either a bad faith theory or a theory that the state interests were insubstantial is foreclosed by the District Court's unchallenged findings of fact. Recovery under a Penn Central analysis is also foreclosed both because petitioners expressly disavowed that theory, and because they did not appeal from the District Court's conclusion that the evidence would not support it. Nonetheless, each of the three per se theories is fairly encompassed within the question that we decided to answer.

With respect to these theories, the ultimate constitutional question is whether the concepts of "fairness and justice" that underlie the Takings Clause will be better served by one of these categorical rules or by a Penn Central inquiry into all of the relevant circumstances in particular cases. From that perspective, the extreme categorical rule that any deprivation of all economic use, no matter how brief, constitutes a compensable taking surely cannot be sustained. Petitioners' broad submission would apply to numerous "normal delays in obtaining building permits, changes in zoning ordinances, variances, and the like," 482 U.S., at 321, as well as to orders temporarily prohibiting access to crime scenes, businesses that violate health codes, fire-damaged buildings, or other areas that we cannot now foresee. Such a rule would undoubtedly require changes in numerous practices that have long been considered permissible exercises of the police power. As Justice Holmes warned in Mahon, "[g]overnment hardly could go on if to some extent values incident to property could not be diminished without paying for every such change in the general law." 260 U.S., at 413. A rule that required compensation for every delay in the use of property would render routine government processes prohibitively expensive or encourage hasty decision-making. Such an important change in the law should be the product of legislative rulemaking rather than
adjudication.30

More importantly, for reasons set out at some length by Justice O'Connor in her concurring opinion in Palazzolo v. Rhode Island, 533 U.S., at 636 (2001), we are persuaded that the better approach to claims that a regulation has effected a temporary taking "requires careful examination and weighing of all the relevant circumstances." In that opinion, Justice O'Connor specifically considered the role that the "temporal relationship between regulatory enactment and title acquisition" should play in the analysis of a takings claim. Id., at 632. We have no occasion to address that particular issue in this case, because it involves a different temporal relationship-the distinction between a temporary restriction and one that is permanent. Her comments on the "fairness and justice" inquiry are, nevertheless, instructive:

"Today's holding does not mean that the timing of the regulation's enactment relative to the acquisition of title is immaterial to the Penn Central analysis. Indeed, it would be just as much error to expunge this consideration from the takings inquiry as it would be to accord it exclusive significance. Our polestar instead remains the principles set forth in Penn Central itself and our other cases that govern partial regulatory takings. Under these cases, interference with investment-backed expectations is one of a number of factors that a court must examine. …

"The Fifth Amendment forbids the taking of private property for public use without just compensation. We have recognized that this constitutional guarantee is ' "designed to bar Government from forcing some people alone to bear public burdens which, in all fairness and justice, should be borne by the public as a whole." ' Penn Central, [438 U.S.], at 123-124 (quoting Armstrong v. United States, 364 U.S. 40, 49 (1960)). The concepts of 'fairness and justice' that underlie the Takings Clause, of course, are less than fully determinate. Accordingly, we have eschewed 'any "set formula" for determining when "justice and fairness" require that economic injuries caused by public action be compensated by the government, rather than remain disproportionately concentrated on a few persons." Penn Central, supra, at 124 (quoting Goldblatt v. Hempstead, 369 U.S. 590, 594 (1962)). The outcome instead 'depends largely "upon the particular circumstances [in that] case." ' Penn Central, supra, at 124 (quoting United States v. Central Eureka Mining Co., 357 U.S. 155, 168 (1958))." Id., at 633.

In rejecting petitioners' per se rule, we do not hold that the temporary nature of a land-use restriction precludes finding that it effects a taking; we simply recognize that it should not be given exclusive significance one way or the other.

A narrower rule that excluded the normal delays associated with processing permits, or that covered only delays of more than a year, would certainly have a less severe impact on prevailing practices, but it would still impose serious financial constraints on the planning process.31 Unlike the "extraordinary circumstance" in which the government deprives a property owner of all economic use, Lucas, 505 U.S., at 1017, moratoria like Ordinance 81-5 and Resolution 83-21 are used widely among land-use planners to preserve the status quo while formulating a more permanent development strategy.32 In fact, the consensus in the planning community appears to be that moratoria, or "interim development controls" as they are often called, are an essential tool of successful development.33 Yet even the weak version of petitioners' categorical rule would treat these interim measures as takings regardless of the good faith of the planners, the reasonable expectations of the landowners, or the actual impact of the moratorium on property values.34

The interest in facilitating informed decisionmaking by regulatory agencies counsels against adopting a per se rule that would impose such severe costs on their deliberations. Otherwise, the financial constraints of compensating property owners during a moratorium may force officials to rush through the planning process or to abandon the practice altogether. To the extent that communities are forced to abandon using moratoria, landowners will have incentives to develop their property quickly before a comprehensive plan can be enacted, thereby fostering inefficient and ill-conceived growth. A finding in the 1980 Compact itself, which presumably was endorsed by all three legislative bodies that participated in its enactment, attests to the importance of that concern. 94 Stat. 3243 ("The legislatures of the States of California and Nevada find that in order to make effective the regional plan as revised by the agency, it is necessary to halt temporarily works of development in the region which might otherwise absorb the entire capability of the region for further development or direct it out of harmony with the ultimate plan").

As Justice Kennedy explained in his opinion for the Court in Palazzolo, it is the interest in informed decisionmaking that underlies our decisions imposing a strict ripeness requirement on landowners asserting regulatory takings claims:

"These cases stand for the important principle that a landowner may not establish a taking before a land-use authority has the opportunity, using its own reasonable procedures, to decide and explain the reach of a challenged regulation. Under our ripeness rules a takings claim based on a law or regulation which is alleged to go too far in burdening property depends upon the landowner's first having followed reasonable and necessary steps to allow regulatory agencies to exercise their full discretion in considering development plans for the property, including the opportunity to grant any variances or waivers allowed by law. As a general rule, until these ordinary processes have been followed the extent of the restriction on property is not known and a regulatory taking has not yet been established. See Suitum [v. Tahoe Regional Planning Agency, 520 U.S. 725, 736, and n. 10 (1997)] (noting difficulty of demonstrating that 'mere enactment' of regulations restricting land use effects a taking)." 533 U.S., at 620-621.

We would create a perverse system of incentives were we to hold that landowners must wait for a taking claim to ripen so that planners can make well-reasoned decisions while, at the same time, holding that those planners must compensate landowners for the delay.

Indeed, the interest in protecting the decisional process is even stronger when an agency is developing a regional plan than when it is considering a permit for a single parcel. In the proceedings involving the Lake Tahoe Basin, for example, the moratoria enabled TRPA to obtain the benefit of comments and criticisms from interested parties, such as the petitioners, during its deliberations.35 Since a categorical rule tied to the length of deliberations would likely create added pressure on decisionmakers to reach a quick resolution of land-use questions, it would only serve to disadvantage those landowners and interest groups who are not as organized or familiar with the planning process. Moreover, with a temporary ban on development there is a lesser risk that individual landowners will be "singled out" to bear a special burden that should be shared by the public as a whole. Nollan v. California Coastal Comm'n, 483 U.S. 825, 835 (1987). At least with a moratorium there is a clear "reciprocity of advantage," Mahon, 260 U.S., at 415, because it protects the interests of all affected landowners against immediate construction that might be inconsistent with the provisions of the plan that is ultimately adopted. "While each of us is burdened somewhat by such restrictions, we, in turn, benefit greatly from the restrictions that are placed on others." Keystone, 480 U.S., at 491. In fact, there is reason to believe property values often will continue to increase despite a moratorium. See, e.g., Growth Properties, Inc. v. Klingbeil Holding Co., 419 F. Supp. 212, 218 (Md. 1976) (noting that land values could be expected to increase 20% during a 5-year moratorium on development). Cf. Forest Properties, Inc. v. United States, 177 F.3d 1360, 1367 (CA Fed. 1999) (record showed that market value of the entire parcel increased despite denial of permit to fill and develop lake-bottom property). Such an increase makes sense in this context because property values throughout the Basin can be expected to reflect the added assurance that Lake Tahoe will remain in its pristine state. Since in some cases a 1-year moratorium may not impose a burden at all, we should not adopt a rule that assumes moratoria always force individuals to bear a special burden that should be shared by the public as a whole.

It may well be true that any moratorium that lasts for more than one year should be viewed with special skepticism. But given the fact that the District Court found that the 32 months required by TRPA to formulate the 1984 Regional Plan was not unreasonable, we could not possibly conclude that every delay of over one year is constitutionally unacceptable.36 Formulating a general rule of this kind is a suitable task for state legislatures.37 In our view, the duration of the restriction is one of the important factors that a court must consider in the appraisal of a regulatory takings claim, but with respect to that factor as with respect to other factors, the "temptation to adopt what amount to per se rules in either direction must be resisted." Palazzolo, 533 U.S., at 636 (O'Connor, J., concurring). There may be moratoria that last longer than one year which interfere with reasonable investment-backed expectations, but as the District Court's opinion illustrates, petitioners' proposed rule is simply "too blunt an instrument," for identifying those cases. Id., at 628. We conclude, therefore, that the interest in "fairness and justice" will be best served by relying on the familiar Penn Central approach when deciding cases like this, rather than by attempting to craft a new categorical rule.

Accordingly, the judgment of the Court of Appeals is affirmed.

It is so ordered.

Notes
1. Often referred to as the "Just Compensation Clause," the final Clause of the Fifth Amendment provides: "… nor shall private property be taken for public use without just compensation." It applies to the States as well as the Federal Government. Chicago, B. & Q. R. Co. v. Chicago, 166 U.S. 226, 239, 241 (1897); Webb's Fabulous Pharmacies, Inc. v. Beckwith, 449 U.S. 155, 160 (1980).

2. According to a Senate Report: "Only two other sizable lakes in the world are of comparable quality-Crater Lake in Oregon, which is protected as part of the Crater Lake National Park, and Lake Baikal in the [former] Soviet Union. Only Lake Tahoe, however, is so readily accessible from large metropolitan centers and is so adaptable to urban development." S. Rep. No. 91-510, pp. 3-4 (1969).

3. The District Court added: "Or at least, for a very, very long time. Estimates are that, should the lake turn green, it could take over 700 years for it to return to its natural state, if that were ever possible at all." 34 F. Supp. 2d, at 1231.

4. App. 104-107. This moratorium did not apply to rights that had vested before the effective date of the 1980 Compact. Id., at 107-108. Two months after the 1980 Compact became effective, TRPA adopted its Ordinance 81-1 broadly defining the term "project" to include the construction of any new residence and requiring owners of land in districts 1, 2, or 3, to get a permit from TRPA before beginning construction of homes on their property. 34 F. Supp. 2d 1226, 1233 (Nev. 1999).

5. As explained above, supra, at 4, the petitioners who purchased land after the 1972 compact did so amidst a heavily regulated zoning scheme. Their property was already classified as part of land capability districts 1, 2, and 3, or SEZ land. And each land classification was subject to regulations as to the degree of artificial disturbance the land could safely sustain.

6. 911 F.2d 1331 (CA9 1990); 938 F.2d 153 (CA9 1991); 34 F.3d 753 (CA9 1994); 216 F.3d 764 (CA9 2000); 611 F. Supp. 110 (Nev. 1985); 808 F. Supp. 1474 (Nev. 1992); 808 F. Supp. 1484 (Nev. 1992).

7. In 1991, petitioners amended their complaint to allege that the adoption of the 1987 plan also constituted an unconstitutional taking. Ultimately both the District Court and the Court of Appeals held that this claim was barred by California's 1-year statute of limitations and Nevada's 2-year statute of limitations. See 216 F.3d, at 785-789. Although the validity of the 1987 plan is not before us, we note that other litigants have challenged certain applications of that plan. See Suitum v. Tahoe Regional Planning Agency, 520 U.S. 725 (1997).

8. In his dissent, The Chief Justice contends that the 1984 plan is before us because the 1980 Compact is a proximate cause of petitioners' injuries, post, at 1-3. Petitioners, however, do not challenge the Court of Appeals' holding on causation in their briefs on the merits, presumably because they understood when we granted certiorari on the question "[w]hether the Court of Appeals properly determined that a temporary moratorium on land development does not constitute a taking of property requiring compensation under the Takings Clause of the United States Constitution," 533 U.S. 948 (2001), we were only interested in the narrow question decided today. Throughout the District Court and Court of Appeals decisions the phrase "temporary moratorium" refers to two things and two things only: Ordinance 81-5 and Resolution 83-21. The dissent's novel theory of causation was not briefed, nor was it discussed during oral argument.

9. As the District Court explained: "There is a direct connection between the potential development of plaintiffs' lands and the harm the lake would suffer as a result thereof. Further, there has been no suggestion by the plaintiffs that any less severe response would have adequately addressed the problems the lake was facing. Thus it is difficult to see how a more proportional response could have been adopted. Given that TRPA's actions had wide-spread application, and were not aimed at an individual landowner, the plaintiffs would appear to bear the burden of proof on this point. They have not met this burden-nor have they really attempted to do so. Although unwilling to stipulate to the fact that TRPA's actions substantially advanced a legitimate state interest, the plaintiffs did not seriously contest the matter at trial." 34 F. Supp., at 1240 (citation omitted).

10. The Penn Central analysis involves "a complex of factors including the regulation's economic effect on the landowner, the extent to which the regulation interferes with reasonable investment-backed expectations, and the character of the government action." Palazzolo v. Rhode Island, 533 U.S. 606, 617 (2001).

11. 34 F. Supp. 2d, at 1241. The court stated that petitioners "had plenty of time to build before the restrictions went into effect-and almost everyone in the Tahoe Basin knew in the late 1970s that a crackdown on development was in the works." In addition, the court found "the fact that no evidence was introduced regarding the specific diminution in value of any of the plaintiffs' individual properties clearly weighs against a finding that there was a partial taking of the plaintiffs' property." Ibid.

12. The pretrial order describes purchases by the United States Forest Service of private lots in environmentally sensitive areas during the periods when the two moratoria were in effect. During the 2-year period ending on August 26, 1983, it purchased 215 parcels in California at an average price of over $19,000 and 45 parcels in Nevada at an average price of over $39,000; during the ensuing 8-month period, it purchased 167 California parcels at an average price of over $29,000 and 27 Nevada parcels at an average price of over $41,000. App. 76-77. Moreover, during those periods some owners sold sewer and building allocations to owners of higher capability lots "for between $15,000 and $30,000." Id., at 77.

13. Ordinance 81-5 specified that it would terminate when the regional plan became finalized. And Resolution 83-21 was limited to 90 days, but was renewed for an additional term. Nevertheless, the District Court distinguished these measures from true "temporary" moratoria because there was no fixed date for when they would terminate. 34 F. Supp. 2d, at 1250-1251.

14. 216 F.3d, at 773. "Below, the district court ruled that the regulations did not constitute a taking under Penn Central's ad hoc approach, but that they did constitute a categorical taking under Lucas [v. South Carolina Coastal Council, 505 U.S. 1003 (1992)]. See Tahoe-Sierra Preservation Council, 34 F. Supp. 2d at 1238-45. The defendants appealed the district court's latter holding, but the plaintiffs did not appeal the former. And even if arguments regarding the Penn Central test were fairly encompassed by the defendants' appeal, the plaintiffs have stated explicitly on this appeal that they do not argue that the regulations constitute a taking under the ad hoc balancing approach described in Penn Central." Ibid.

15. The Court of Appeals added: "Each of these three types of regulation will have an impact on the parcel's value, because each will affect an aspect of the owner's 'use' of the property-by restricting when the 'use' may occur, where the 'use' may occur, or how the 'use' may occur. Prior to Agins [v. City of Tiburon, 447 U.S. 255 1980)], the Court had already rejected takings challenges to regulations eliminating all 'use' on a portion of the property, and to regulations restricting the type of 'use' across the breadth of the property. See Penn Central, 438 U.S. at 130-31; Keystone Bituminous Coal Ass'n, 480 U.S. at 498-99; Village of Euclid v. Ambler Realty Co., 272 U.S. 365, 384, 397 … (1926) (75% diminution in value caused by zoning law); see also William C. Haas & Co. v. City & County of San Francisco, 605 F.2d 1117, 1120 (9th Cir. 1979) (value reduced from $2,000,000 to $100,000). In those cases, the Court 'uniformly reject[ed] the proposition that diminution in property value, standing alone, can establish a "taking." ' Penn Central, 438 U.S. at 131…; see also Concrete Pipe and Products, Inc. v. Construction Laborers Pension Trust, 508 U.S. 602, 645 … (1993). There is no plausible basis on which to distinguish a similar diminution in value that results from a temporary suspension of development." Id., at 776-777.

16. Despite our clear refusal to hold that a moratorium never effects a taking, The Chief Justice accuses us of "allow[ing] the government to … take private property without paying for it," post, at 8. It may be true that under a Penn Central analysis petitioners' land was taken and compensation would be due. But petitioners failed to challenge the District Court's conclusion that there was no taking under Penn Central. Supra, at 12.

17. In determining whether government action affecting property is an unconstitutional deprivation of ownership rights under the Just Compensation Clause, a court must interpret the word "taken." When the government condemns or physically appropriates the property, the fact of a taking is typically obvious and undisputed. When, however, the owner contends a taking has occurred because a law or regulation imposes restrictions so severe that they are tantamount to a condemnation or appropriation, the predicate of a taking is not self-evident, and the analysis is more complex.

18. To illustrate the importance of the distinction, the Court in Loretto, 458 U.S., at 430, compared two wartime takings cases, United States v. Pewee Coal Co., 341 U.S. 114, 116 (1951), in which there had been an "actual taking of possession and control" of a coal mine, and United States v. Central Eureka Mining Co., 357 U.S. 155 (1958), in which "by contrast, the Court found no taking where the Government had issued a wartime order requiring nonessential gold mines to cease operations … ." 458 U.S., at 431. Loretto then relied on this distinction in dismissing the argument that our discussion of the physical taking at issue in the case would affect landlord-tenant laws. "So long as these regulations do not require the landlord to suffer the physical occupation of a portion of his building by a third party, they will be analyzed under the multifactor inquiry generally applicable to nonpossessory governmental activity." Id., at 440 (citing Penn Central).

19. According to The Chief Justice's dissent, even a temporary, use-prohibiting regulation should be governed by our physical takings cases because, under Lucas v. South Carolina Coastal Council, 505 U.S. 1003, 1017 (1992), "from the landowner's point of view," the moratorium is the functional equivalent of a forced leasehold, post, at 6-7. Of course, from both the landowner's and the government's standpoint there are critical differences between a leasehold and a moratorium. Condemnation of a leasehold gives the government possession of the property, the right to admit and exclude others, and the right to use it for a public purpose. A regulatory taking, by contrast, does not give the government any right to use the property, nor does it dispossess the owner or affect her right to exclude others. The Chief Justice stretches Lucas' "equivalence" language too far. For even a regulation that constitutes only a minor infringement on property may, from the landowner's perspective, be the functional equivalent of an appropriation. Lucas carved out a narrow exception to the rules governing regulatory takings for the "extraordinary circumstance" of a permanent deprivation of all beneficial use. The exception was only partially justified based on the "equivalence" theory cited by his dissent. It was also justified on the theory that, in the "relatively rare situations where the government has deprived a landowner of all economically beneficial uses," it is less realistic to assume that the regulation will secure an "average reciprocity of advantage," or that government could not go on if required to pay for every such restriction. 505 U.S., at 1017-1018. But as we explain, infra, at 35-38, these assumptions hold true in the context of a moratorium.

20. The case involved "a bill in equity brought by the defendants in error to prevent the Pennsylvania Coal Company from mining under their property in such way as to remove the supports and cause a subsidence of the surface and of their house." Mahon, 260 U.S., at 412. Mahon sought to prevent Pennsylvania Coal from mining under his property by relying on a state statute, which prohibited any mining that could undermine the foundation of a home. The company challenged the statute as a taking of its interest in the coal without
compensation.

21. In Lucas, we explained: "Prior to Justice Holmes's exposition in Pennsylvania Coal Co. v. Mahon, 260 U.S. 393 (1922), it was generally thought that the Takings Clause reached only a 'direct appropriation' of property, Legal Tender Cases, 12 Wall. 457, 551, (1871), or the functional equivalent of a 'practical ouster of [the owner's] possession,' Transportation Co. v. Chicago, 99 U.S. 635, 642 (1879) . … Justice Holmes recognized in Mahon, however, that if the protection against physical appropriations of private property was to be meaningfully enforced, the government's power to redefine the range of interests included in the ownership of property was necessarily constrained by constitutional limits. 260 U.S., at 414-415. If, instead, the uses of private property were subject to unbridled, uncompensated qualification under the police power, 'the natural tendency of human nature [would be] to extend the qualification more and more until at last private property disappear[ed].' Id., at 415. These considerations gave birth in that case to the oft-cited maxim that, 'while property may be regulated to a certain extent, if regulation goes too far it will be recognized as a taking.' Ibid." 505 U.S., at 1014 (citation omitted).

22. Justice Brandeis argued: "Every restriction upon the use of property imposed in the exercise of the police power deprives the owner of some right theretofore enjoyed, and is, in that sense, an abridgment by the State of rights in property without making compensation. But a restriction imposed to protect the public health, safety or morals from dangers threatened is not a taking. The restriction here in question is merely the prohibition of a noxious use. The property so restricted remains in the possession of its owner. The State does not appropriate it or make any use of it. The State merely prevents the owner from making a use which interferes with paramount rights of the public." Mahon, 260 U.S., at 417 (Brandeis, J., dissenting).

23. In her concurring opinion in Palazzolo, 533 U.S., at 633, Justice O'Connor reaffirmed this approach: "Our polestar instead remains the principles set forth in Penn Central itself and our other cases that govern partial regulatory takings. Under these cases, interference with investment-backed expectations is one of a number of factors that a court must examine." Ibid. "Penn Central does not supply mathematically precise variables, but instead provides important guideposts that lead to the ultimate determination whether just compensation is required." Id., at 634. "The temptation to adopt what amount to per se rules in either direction must be resisted. The Takings Clause requires careful examination and weighing of all the relevant circumstances in this context." Id., at 636.

24. Justice Kennedy concurred in the judgment on the basis of the regulation's impact on "reasonable, investment-backed expectations." 505 U.S., at 1034.

25. It is worth noting that Lucas underscores the difference between physical and regulatory takings. See supra, at 17-19. For under our physical takings cases it would be irrelevant whether a property owner maintained 5% of the value of her property so long as there was a physical appropriation of any of the parcel.

26. The Chief Justice's dissent makes the same mistake by carving out a 6-year interest in the property, rather than considering the parcel as a whole, and treating the regulations covering that segment as analogous to a total taking under Lucas, post, at 9.

27. Armstrong, like Lucas, was a case that involved the "total destruction by the Government of all value" in a specific property interest. 364 U.S., at 48-49. It is nevertheless perfectly clear that Justice Black's oft-quoted comment about the underlying purpose of the guarantee that private property shall not be taken for a public use without just compensation applies to partial takings as well as total takings.

28. Brief for the Institute for Justice as Amicus Curiae 30. Although amicus describes the 1-year cut off proposal as the "better approach by far," ibid., its primary argument is that Penn Central should be overruled, id., at 20 ("All partial takings by way of land use restriction should be subject to the same prima facie rules for compensation as a physical occupation for a limited period of time").

29. Brief for Petitioners 44. See also Pet. for Cert. i.

30. In addition, we recognize the anomaly that would be created if we were to apply Penn Central when a landowner is permanently deprived of 95% of the use of her property, Lucas, 505 U.S., at 1019, n. 8, and yet find a per se taking anytime the same property owner is deprived of all use for only five days. Such a scheme would present an odd inversion of Justice Holmes' adage: "A limit in time, to tide over a passing trouble, well may justify a law that could not be upheld as a permanent change." Block v. Hirsh, 256 U.S. 135, 157 (1921).

31. Petitioners fail to offer a persuasive explanation for why moratoria should be treated differently from ordinary permit delays. They contend that a permit applicant need only comply with certain specific requirements in order to receive one and can expect to develop at the end of the process, whereas there is nothing the landowner subject to a moratorium can do but wait, with no guarantee that a permit will be granted at the end of the process. Brief for Petitioners 28. Setting aside the obvious problem with basing the distinction on a course of events we can only know after the fact-in the context of a facial challenge-petitioners' argument breaks down under closer examination because there is no guarantee that a permit will be granted, or that a decision will be made within a year. See, e.g., Dufau v. United States, 22 Cl. Ct. 156 (1990) (holding that 16-month delay in granting a permit did not constitute a temporary taking). Moreover, under petitioners' modified categorical rule, there would be no per se taking if TRPA simply delayed action on all permits pending a regional plan. Fairness and justice do not require that TRPA be penalized for achieving the same result, but with full disclosure.

32. See, e.g., Santa Fe Village Venture v. Albuquerque, 914 F. Supp. 478, 483 (N. M. 1995) (30-month moratorium on development of lands within the Petroglyph National Monument was not a taking); Williams v. Central, 907 P.2d 701, 703-706 (Colo. App. 1995) (10-month moratorium on development in gaming district while studying city's ability to absorb growth was not a compensable taking); Woodbury Place Partners v. Woodbury, 492 N. W. 2d 258 (Minn. App. 1993) (moratorium pending review of plan for land adjacent to interstate highway was not a taking even though it deprived property owner of all economically viable use of its property for two years); Zilber v. Moranga, 692 F. Supp. 1195 (ND Cal. 1988) (18-month development moratorium during completion of a comprehensive scheme for open space did not require compensation). See also Wayman, Leaders Consider Options for Town Growth, Charlotte Observer, Feb. 3, 2002, p. 15M (describing 10-month building moratorium imposed "to give town leaders time to plan for development"); Wallman, City May Put Reins on Beach Projects, Sun-Sentinel, May 16, 2000, p. 1B (2-year building moratorium on beachfront property in Fort Lauderdale pending new height, width, and dispersal regulations); Foderaro, In Suburbs, They're Cracking Down on the Joneses, N. Y. Times, Mar. 19, 2001, p.

Roberts, Land Use Planning and Control Law §§5.28(G) and 9.6 (1998); Garvin & Leitner, Drafting Interim Development Ordinances: Creating Time to Plan, 48 Land Use Law & Zoning Digest 3 (June 1996) ("With the planning so protected, there is no need for hasty adoption of permanent controls in order to avoid the establishment of nonconforming uses, or to respond in an ad hoc fashion to specific problems. Instead, the planning and implementation process may be permitted to run its full and natural course with widespread citizen input and involvement, public debate, and full consideration of all issues and points of view"); Freilich, Interim Development Controls: Essential Tools for Implementing Flexible Planning and Zoning, 49 J. Urb. L. 65 (1971).

34. The Chief Justice offers another alternative, suggesting that delays of six years or more should be treated as per se takings. However his dissent offers no explanation for why 6 years should be the cut-off point rather than 10 days, 10 months, or 10 years. It is worth emphasizing that we do not reject a categorical rule in this case because a 32-month moratorium is just not that harsh. Instead, we reject a categorical rule because we conclude that the Penn Central framework adequately directs the inquiry to the proper considerations-only one of which is the length of the delay.
