FINDINGS OF FACT, CONCLUSIONS OF LAW, and ORDER EDWARD C. REED, Jr., District Judge. On December 1, 1998, after fourteen and a half years of litigation, the first phase of the trial in this action finally began. The case involves approximately 449 plaintiffs who own property in the Lake Tahoe Basin. The lead plaintiff, Tahoe-Sierra Preservation Council, Inc. (“TSPC”), is an association of Tahoe area property owners. Each of the individual plaintiffs has alleged that several ordinances enacted in the early 1980s by the defendant, Tahoe Regional Planning Agency (“TRPA”), effected takings of his or her property under the Fifth and Fourteenth Amendments to the United States Constitution. Given the complexity of the ease, as well as the sweeping changes in the law of regulatory takings that have occurred in the past fifteen years, it is, while unfortunate, not surprising that the case has been pending for so long. The first ten years or so were spent largely in an effort to determine whether any of the claims in the case were justiciable at all. Clearly, however, the effort expended in this case-by all the parties and by the courts-has not been wasted. The dispute here is not over something trivial or unimportant. For what is at stake, at least in part, is the survival of Lake Tahoe, one of the wonders of the natural world. Whatever the ultimate outcome of this case, the fate of the lake deserves serious attention and thought. That, it has unquestionably received. The very tenacity with which the property owners herein have pursued their claims supports the idea that the lake is worth fighting for. Were the Tahoe Basin not such a beautiful, desirable place to spend time, it is doubtful that the plaintiffs would have pursued their claims quite as vigorously, or in quite the same manner, as they have done over the years. Unsurprisingly, a case pending for such a long period of time picks up something of a history along the way. Here, that history consists, in part, of three published Ninth Circuit opinions, at least five published district court opinions, and numerous unpublished district court orders. These orders and opinions have significantly narrowed and defined the scope of this case. Of course, many of these opinions also set forth versions of the facts, or some of the facts, involved in the case. We do not find it appropriate merely to refer to earlier statements of the facts, however, given that those statements were largely prepared in ruling on motions to dismiss or motions for summary judgment, where, certain assumptions are made that may not always find themselves borne out by the evidence produced at trial. We thus present a complete discussion of the facts herein; we base our findings on the evidence and testimony presented at trial, and the stipulations agreed to by the parties. FINDINGS OF FACT Lake Tahoe, the dominant presence in this litigation, is a remarkable alpine lake located in the northern Sierra Nevada mountains. The lake is almost indescribably beautiful. Nonetheless, many have tried to describe it-the most notable of whom (and certainly the most quoted, at least during this trial) is Mark Twain. Twain, while famous for his hyperbole, cannot be said to have exaggerated the beauty of Lake Tahoe, which he described as: a noble sheet of blue water lifted six thousand three hundred feet above the level of the sea, and walled in by a rim of snow-clad mountain peaks that towered aloft full three thousand feet higher still! ... As it lay there with the shadows of the mountains brilliantly photographed upon its still surface I thought it must be the fairest picture the whole earth affords. Mark Twain, Roughing It 169 (facsimile reprint of 1st ed., Hippoerene Books, n.d.) (1872). Further, the lake: was glassy and clear, or rippled and breezy, or black and storm-tossed, according to Nature’s mood; and its circling border of mountain domes, clothed with forests, scarred with land-slides, cloven by cañons and valleys, and helmeted with glittering snow, fitly framed and finished the noble picture. The eye was never so tired of gazing, day or night, in calm or storm; it suffered but one grief, and that was that it could not look always, but must close sometimes in sleep. Id. at 173. Othei-s, too, have attempted to describe the beauty of the lake, including sources more commonly cited in judicial opinions than Mark Twain. These include the Supreme Courts of California and Nevada, and even the President and Vice President of the United States. In July of 1997, Px-esident Clinton and Vice President Gore both attended the “Lake Tahoe Presidential Forum” in Incline Village, Nevada, on the northeast shore of the lake. The President referred to Lake Tahoe as “one of the crown jewels, unique among them all. It’s a national treasure that must be protected and preserved.” Sean Whaley, Clinton Pledges Tahoe Aid, Las Vegas Rev.-J., July 27, 1997, at 1A. The Vice President stated that, “There is a peace associated with Lake Tahoe that is very, very special.... The beauty of this place is unique in all the world.” Sean Whaley, Gore Vows to Protect Lake, Las Vegas Rev.-J., July 26, 1997, at 1A. The Nevada Supreme Court called the lake a “national treasure,” Kelly v. Tahoe Reg’l Planning Agency, 109 Nev. 638, 855 P.2d 1027, 1034 (1993), and the California Supreme Court referred to the Basin as “an area of unique and unsurpassed beauty.” People ex rel. Younger v. County of El Dorado, 5 Cal.3d 480, 96 Cal.Rptr. 553, 487 P.2d 1193, 1194 (Cal.1971). The plaintiffs, quite wisely, do not dispute the fact that Lake Tahoe is uniquely beautiful. Ironically, the more Lake Tahoe comes to be appreciated for its beauty, the more that beauty is threatened. Part of what makes Tahoe so special is the amazing clarity of its water, which, as a result of its clarity, is an unusually beautiful cobalt blue color. Again, we revert to Mark Twain for a description. He described the clarity of Tahoe’s water as follows: So singularly clear was the watei', that whei'e it was only twenty or thirty feet deep the bottom was so perfectly distinct that the boat seemed floating in the air! Yes, where it was even eighty feet deep. Every little pebble was distinct, every speckled ti'out, every hand’s-breadth of sand.... Down through the ti'ansparency of these great depths, the water was not merely ti-ansparent, but dazzlingly, brilliantly so. All objects seen through it had a bright, strong vividness, not only of outline, but of every minute detail, which they would not have had when seen simply through the same depth of atmosphere. So empty and airy did all the spaces seem below us, and so strong was the sense of floating high aloft in mid-nothingness, that we called these boat-excursions “balloon-voyages.” Twain, Roughing It 174-75 (emphasis in original); see also Mark Twain, Innocents Abroad 262-265 (Harper & Brothers 1911) (1869) (comparing Lake Tahoe to Italy’s Lake Como). Most lakes lack anything approaching this clarity, usually because of the presence of algae growing in their depths. Algae requires a nutrient-rich environment in which to grow, and most lakes contain sufficient amounts of the requisite nutrients to feed considerable algal growth. Not so Lake Tahoe, however, which has historically been lacking in both nitrogen and phosphorous, two of the nutrients algae requires. A lake which is deficient in such plant nutrients, like Tahoe, is “oligotrophic.” Unfortunately, this is rapidly changing. The clarity of the lake has been decreasing by at least a foot a year. As algal growth in the lake increases, its clarity decreases. In other words, the lake undergoes what is termed “eutrophication.” Eutrophication is the process of becoming more “eutrophic,” which, at least as it relates to a lake, is defined as “rich in dissolved nutrients .... ” Webster’s Third New International Dictionary 786 (1976). Eventually, unless the process is stopped, the lake will lose its clarity and its trademark blue color, becoming green and opaque for eternity. 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. The increase in algal growth, and the attendant loss in water clarity, is caused by an increase in the amounts of nitrogen and phosphorous reaching the lake. The evidence clearly shows that this increase in nutrient levels is caused by increased development in the Lake Tahoe Basin (“the Basin”). Dramatic decreases in clarity first began to be noted in the late 1950s/early 1960s, shortly after development at the lake began in earnest in the 1950s. Clarity has decreased steadily since then. Even today, increased algal growth is more noticeable in areas of the lake near larger concentrations of human habitation and development. Increased development causes increased nutrient loading of the lake largely because of the increase in impervious coverage of land in the Basin resulting from that development. 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. Apparently, even the force of a raindrop falling on bare earth has some erosive power, which the presence of vegetation mitigates. Thus disruptions to the natural plant cover caused by development further exacerbate the problem. The increase in impervious coverage seems to be a larger problem than the loss of plant cover, however-perhaps because so much of the Basin’s precipitation falls in the form of snow. One can only assume that a snowflake impacts the ground with less force than a raindrop. Yet runoff from the melting snow still produces erosion. The concentrations of water running off areas of impervious coverage then flow rapidly over areas of uncovered earth, picking up nutrient-rich topsoil and bits of vegetation and debris as they go. The increase in runoff thus causes more debris and soil-and hence more nitrogen and phosphorous-to reach the lake than under natural conditions. Generally speaking, the steeper the slope, the more runoff will occur. Thus areas with steeper slopes are usually considered “high hazard” lands. Of course, there is always some naturally occurring runoff. Normally, however, much of the runoff from upper elevations never reaches the lake. Instead, certain areas near streams and other wetlands-known as Stream Environment Zones (“SEZs”)-act as filters for much of the debris that runoff carries. When SEZ lands are filled in and paved over, however, they cease to perform their natural function. Thus not only do the paved-over SEZ lands increase erosion due to the new impervious coverage, they also fail to mitigate erosion occurring at higher elevations farther from the lake. SEZ lands are therefore considered especially sensitive to the impact of development. The most obvious response to this problem, of course, is to restrict development around the lake-espeeially in SEZ lands, as well as in areas already naturally prone to runoff. Given the high desirability of the Tahoe Basin as a place to live and to vacation, however, restrictions on development, when they were imposed, were not well-received by all parties involved. Of course, if no one wanted to live there, no restrictions on development would have been necessary-leading the California Supreme Court to remark, almost thirty years ago, that “the region’s natural wealth contains the virus of its ultimate impoverishment.” People ex rel. Younger v. County of El Dorado, 5 Cal.3d 480, 96 Cal.Rptr. 553, 487 P.2d 1193, 1194 (1971). Clearly, though, people do want to live there-or at least vacation there. More people come to Lake Tahoe every year. While this classic struggle between development and the environment has been played out all over the country, the Tahoe area has seen some particularly epic battles of this kind. The developing environmental problems at the lake first received significant attention in the 1960s. Given that two states, five counties, several municipalities, and the federal government (which, through the U.S. Forest Service, owns a large percentage of the land in the Basin) have jurisdiction over part of the lake or the surrounding area, the need for some type of coordinated response to the problem was obvious. Thus in 1969, the bi-state Tahoe Regional Planning Compact was approved by the United States Congress, after being passed by the legislatures of both Nevada and California. Pub.L. No. 91-148, 83 Stat. 360; 1967 Cal. Stat. ch. 1589, p. 3804, § 1, amended by 1968 Cal. Stat. ch. 988, p.1900, § 1; 1968 Nev. Stat. 4. The Compact created the defendant TRPA, and set goals for the preservation of the lake and the surrounding Basin. Pursuant to the Compact, TRPA adopted, in 1972, Ordinance No. 4, a Land Use Ordinance which incorporated what is commonly known as the Bailey system. TRPA Ordinance No. 4, §§ 5.00, 6.00 (Defs.’ Ex. 201). The Bailey system, named for its developer, Robert G. Bailey, classifies land in the Tahoe Basin according to how prone to environmental damage it is. See generally, Robert G. Bailey, Forest Service, U.S. Dept. of Agriculture, Land-Capability Classification of the Lake Tahoe Basin, California-Nevada: A Guide for Planning (1974) (Defs.’ Ex. 203). Generally speaking, land with steeper slopes is naturally more prone to runoff, so even slight disturbances in vegetation or increases in land coverage can result in large increases in nutrient runoff. Bailey thus divided land in the Basin into seven “land capability districts,” based largely on steepness, but also taking into account flood hazard, high water tables, poorly drained soils, landslides, fragile flora and fauna, and soil erodibility. These land capability districts are numbered 1 through 7, with 1 being the most environmentally sensitive, and 7 the least (relatively speaking). Each land capability district was assigned a land coverage coefficient-a recommended limit on the percentage of such land that could be covered by impervious surface. The coefficients are as follows: land capability districts 1 and 2 1% land capability district 3 5% land capability district 4 20% land capability district 5 25% land capability districts 6 and 7 30% Generally, land capability districts 1 through 3, because of the higher risk of erosion associated with these areas, are grouped together and denominated “high hazard” or “sensitive” lands, while land capability districts 4 through 7 are referred to as “low hazard” or “non-sensitive” lands. (Actually, Bailey himself grouped them slightly differently, but that is how TRPA grouped them for planning purposes, and how they have been grouped throughout this litigation.) On average, “Class 1-3 lands” are the steepest lands in the Basin. SEZ lands constitute a special category of high hazard lands, and are classified as “lb” lands-sort of a subsection of land capability district 1. While SEZ lands are generally much less steep than other district 1 lands, they are nonetheless extremely sensitive, due to the nature of the function they perform when left in their natural state, as discussed above. Throughout, we refer to “Class 1-3 lands” and “SEZ lands” separately; although technically the term “Class 1-3” could be read to include SEZ (or lb) lands, for clarity we have defined the term to exclude SEZ lands. However, although Ordinance No. 4 adopted the Bailey system, it allowed numerous exceptions to the coverage recommendations. The building of new residential housing was not particularly limited. This led to significant dissatisfaction with TRPA’s regulatory scheme. It became evident that the environment was continuing to decline, and that the 1969 Compact was not strong enough to fix the problem. California became so dissatisfied that it pulled its funding from TRPA, and its own agency, the California Tahoe Regional Planning Agency (formed in 1967, prior to the adoption of the Compact), began to impose stricter regulations on that part of the Basin lying within California. Eventually, this dissatisfaction led to the amendment of the Tahoe Regional Planning Compact in 1980. Pub.L. No. 96-551, 94 Stat. 3233; 1980 Cal. Stat. ch. 872, p. 2710, § 2, codified at Cal. Gov’t Code § 66801; 1980 Nev. Stat. 1, codified at N.R.S. 277.200 (the “1980 Compact”). The 1980 Compact restructured TRPA and its voting procedures, and directed it to establish environmental threshold carrying capacities and a new regional plan within a strict time table. The amended Compact became effective December 19, 1980; TRPA was required to adopt threshold carrying capacities within 18 months of that date, and a new regional plan within 12 months of the adoption of the carrying capacities. In addition, the amended Compact required that TRPA review all projects, and established temporary restrictions on development in the Basin pending the enactment of a new regional plan. In addition to the requirements of the Compact, TRPA was faced with the need to develop a regional water quality plan, or 208 plan, as required by the EPA under the Clean Water Act, 33 U.S.C. § 1288 (1986). Although TRPA had proposed a 208 plan in 1979, California had rejected it, and agreement on a plan had still not been reached by the time the Compact was amended. Thus at the same time TRPA was grappling with the new Compact requirements, it was still embroiled in debate over the 208 plan. The plaintiffs have pointed to the fact that TRPA expended resources during the time immediately following the Compact’s amendment on an (ultimately successful) attempt to develop a 208 plan, and have claimed that this is some kind of evidence that TRPA acted in bad faith in complying with the Compact requirements. This argument is completely meritless. TRPA was under an obligation to development a 208 plan, and the agency clearly approached its obligations under both the Compact and the Clean Water Act with good faith and to the best of its ability. In addition, we note that much of the work done in preparing the 208 Plan was also necessary to the development of the regional plan, specifically the establishment of the threshold carrying capacities required by the Compact. However, it is primarily the agency’s response to the amended Compact that, inevitably, set this litigation in motion. On February 26,1981, TRPA adopted Ordinance 81-1, which elaborated on what was meant by the term “project,” as defined in the Compact. The Compact defined “project” as “an activity undertaken by any person, including any public agency, if the activity may substantially affect the land, water, air, space or any other natural resources of the region”; required all “projects” to be approved by TRPA; and directed the agency to “prescribe by ordinance those activities which it has determined will not have a substantial effect on the land, water, air, space or any other natural resources in the region and therefore will be exempt from its review and approval.” 1980 Compact, Article 11(h), Article VI(a)-(b). In other words, TRPA was required to identify what were not projects. This TRPA did in Ordinance 81-1. In relevant part, 81-1 made clear that the construction of new, single-family homes in “critical areas” (defined to include Class 1-3 lands and SEZ lands) was considered a “project” (subject to a minor exception for certain already approved subdivisions). TRPA Ordinance 81-1, § 3 .12 (Defs.’ Ex. 217). Thus Ordinance 81-1 made it clear that, for the most part, owners of Class 1-3 and SEZ lands were required to get a permit from TRPA before beginning construction of homes on their property. Then, several months later, TRPA adopted Ordinance 81-5, the first of the three actions actually challenged in this case. The ordinance was enacted on June 25, 1981, with an effective date of August 24, 1981. TRPA Ordinance 81-5, § 16.00 (Defs.’ Ex. 227). Even the defendants have admitted that Ordinance 81-5 “temporarily prohibit[ed] most residential and all commercial construction on land capability districts 1, 2, 3 and SEZs until a new regional plan was developed.” Defs.’ Tr. Br. at 13. Ordinance 81-5 actually amended the existing regional plan, referred to by its implementing ordinance, Ordinance No. 79-10. First, Ordinance 81-5 amended § 12.00 of Ordinance 79-10, entitled “Regulation of Development on High-Erosion and High-Runoff Hazard Lands.” The amended section 12.00 provided that land in capability districts 1 through 3 (excluding SEZ lands) would be subject to a classification review, which came to be known as “case-by-case” review. The amendments to § 12.00 went on to provide that: Except as otherwise provided by this ordinance, no person shall perform any construction, work, use or activity, including without limitation, grading, clearing, removal of vegetation, filling or creation of land coverage, upon land within land capability districts la, lc, 2 and 3 without first obtaining a permit from the Agency. The application for such a permit shall be reviewed and approved as a “project” pursuant to the Compact and the Rules and Regulations of Practice and Procedure of the Agency.... TRPA Ordinance 81-5, § 2.20 (amending § 12.21 of Ordinance 79-10). Although specific findings were required for approval of any application that would result in land coverage in excess of the Bailey coefficients, such excess coverage was permitted. The coverage limitations in force were actually those set forth in § 9.24 of the Land Use Ordinance, or Ordinance No. 4 (Defs.’ Ex. 201), or “twenty percent (20%) of the area of the pertinent lot or parcel, whichever is less.” TRPA Ordinance 81-5, § 2.20 (amending § 12.23 of Ordinance 79-10). The coverage limitations of § 9.24 of Ordinance No. 4 were less restrictive than the Bailey coefficients. New commercial land coverage, on the other hand, was restricted to amounts consistent with the Bailey coefficients, at least in land capability districts 1-3 and SEZ lands. TRPA Ordinance 81-5, § 2.20 (amending § 12.40 of Ordinance 79-10). Further, § 12.60 was amended to read as follows: Except as otherwise provided by this ordinance, and subject to the exceptions set forth in this subsection, no person shall perform any grading, clearing, removal of vegetation, filling or creation of land coverage upon land within land capability districts la, lc, 2 and 3. TRPA Ordinance 81-5 (amending § 12.60 of Ordinance 79-10). The exceptions referred to included already approved subdivisions, public works projects, areas already so modified by man that the land capability characteristics had been fundamentally changed (“man-modified areas”), approved erosion control work, and “outdoor recreation facilities.” Id. Finally, the amendment provided for administrative challenges to land capability district classifications. As to SEZ lands, the amendments provided for much more strict prohibitions on development: Notwithstanding any other provision of this ordinance or of any other ordinance of the Agency, no person shall perform any grading, clearing, removal of vegetation, filling or creation of land coverage, within or upon a stream environment zone (“SEZ”), as described or depicted upon maps contained in the Plan. TRPA Ordinance 81-5, § 3.00 (amending § 13.00 of Ordinance 79-10). Further, Notwithstanding any other provision of this ordinance or of any other ordinance of the Agency, no person shall perform any construction, work, use or activity upon a lot or parcel containing an SEZ without first obtaining a permit from the Agency, the application for which permit shall be reviewed and approved as a “project” .... Such application shall not be approved unless it is found by the Agency that it proposes no grading, clearing, removal of vegetation, filling or creation of land coverage within the SEZ .... Id. The only exceptions for SEZ lands are for certain public works projects, man-modified areas, and approved erosion control work. Again, however, administrative challenges to a property’s classification were allowed. The other relevant provisions of Ordinance 81-5 deal with its applicability. On a first reading, the provisions of the ordinance that allow for the possibility of some construction in Class 1-3 lands appear to apply to all land in the Basin. See TRPA Ordinance 81-5, § 10.00 (amending § 20.00 of Ordinance 79-10). However, § 20.20 of Ordinance 79-10 was amended to continue in effect certain listed provisions of the California State Water Resources Control Board’s Lake Tahoe Water Quality Plan, with respect to the California side of the Basin. Those provisions essentially barred new development in California on SEZ lands-or anywhere in excess of the Bailey coefficients. Defs.’ Ex. 211. The final provision of Ordinance 81-5 that concerns us now relates to its effect date, which was defined as sixty days after the date of its adoption. TRPA Ordinance 81-5, § 16.00. As the ordinance was adopted on June 25, 1981, it became effective on August 24, 1981. The effect of Ordinance 81-5 as to SEZ lands was thus to prohibit any construction, work, use or activity that involved any form of grading, clearing, removal of vegetation, filling or creation of land coverage-with or without a permit. Uses or activities that did not involve grading, clearing, removal of vegetation, filling or creation of land coverage appear to have been allowed-if a permit was obtained. The plain language of the ordinance thus seems to imply that even hiking or picnicking on SEZ land in its natural state would require a permit, although it is hard to imagine that TRPA would have enforced the ordinance so literally. These restrictions appear to be effectively the same in both Nevada and California. As to Class 1-3 lands, however, there is a significant difference between'Nevada and California. In Nevada, the provisions of Ordinance 81-5 allowed for construction, work, uses or activities, including those that involved grading, clearing, removal of vegetation, filling or creation of land coverage-including land coverage in excess of the Bailey eoefficients-so long as a permit was obtained. Permits for such activities were obtainable, provided that certain findings were made. In California, however, no coverage in excess of the Bailey coefficients was allowed. As on SEZ lands, however, the language of the ordinance indicates that nothing could be done without a permit. For Class 1-3 lands, however, this might have been somewhat modified by Ordinance 81-1, which provided for “minor grading” without a permit. After the adoption of 81-5, which also implemented some details of the final 208 plan, TRPA turned its attention more completely to the task of developing threshold carrying capacities as mandated by the Compact. From the date Ordinance 81-5 was adopted, TRPA had approximately one year remaining under the Compact’s schedule in which to develop carrying capacities. “Environmental threshold carrying capacity” was defined by the 1980 Compact as “an environmental standard necessary to maintain a significant scenic, recreational, educational, scientific or natural value of the region or to maintain public health and safety within the region.” 1980 Compact, Article II(i). Faced with a complex task and a divided Governing Board, it is unsurprising that TRPA did not quite meet the Compact deadline of June 19, 1982. Instead, threshold carrying capacities were adopted on August 26, 1982, roughly two months behind schedule-which, given the circumstances, was not terrible. TRPA Resolution No. 82-11 (Defs.’ Ex. 244). Under a liberal reading of the Compact, TRPA then had one year from the adoption of the thresholds in which to adopt a new regional plan-or until August 26, 1983. Unfortunately, but again not surprisingly, no regional plan was in place as of that date. Worried that, once the Compact’s time limit had been exceeded, TRPA had no jurisdiction to continue issuing construction permits, the agency took the second of the three actions challenged here-it adopted Resolution 83-21, which completely suspended all project reviews and approvals, including the acceptance of new proposals, for a period of ninety days, or until November 26, 1983. TRPA Resolution 83-21 (Defs.’ Ex. 275). Since a permit was required for almost any use of Class 1-3 or SEZ lands at all, this moratorium essentially prohibited the commencement of any new use of such land. At the end of ninety days, the ban was extended-although not by any affirmative action by TRPA, and not, contrary to what the defendants have implied, for any set period of time. The Minutes of the TRPA Governing Board regular meeting held November 17, 1983, indicate that TRPA staff members advised the Board that the end of the ninety day period was approaching, and that, absent an order by the Board to the contrary, the staff would continue to observe the moratorium, since the conditions that had led to its imposition in the first place still existed. Defs.’ Ex. 286. That is, there was still no regional plan. Since the Board never took any action in response to this “advice,” the moratorium was, in fact, continued in effect by the staff. Finally, however, on April 26, 1984, a new regional plan was adopted. TRPA Ordinance 84-1 (Defs.’ Ex. 299). The temporary moratorium initiated by Resolution 83-21 thus ended up lasting approximately eight months. With respect to Class 1-3 and SEZ properties, however, not much changed. The 1984 Plan provided, at least temporarily, that no projects proposing any land coverage at all in Class 1-3 and SEZ lands would be considered, with limited exceptions for “regional public facilities, public outdoor recreation facilities and public works projects.” TRPA Ordinance 84-1, § 4.30(2) (Defs.’ Ex. 299) (incorporating by reference the document entitled “Project Review Under Adopting Ordinance,” dated March 28,1984). This prohibition may or may not have been intended to become permanent, but the provisions relating to high hazard lands, as well as numerous other provisions, apparently still had not quite been agreed upon at the time Ordinance 84-1 was adopted, and temporary measures were enacted in the interim. See, e.g., TRPA Ordinance 84-1, § 2.12 (the plan area statements were “adopted as an interim policy guideline, effective until September 1, 1984, unless otherwise provided ... ”). As part of these temporary measures, the provisions of Ordinance 81-6 for approving projects were continued in force. But no further refinements to the 1984 Plan were ever made. The very day that the new regional plan was adopted, the State of California filed suit against TRPA to block the plan’s implementation. The next day, April 27, an environmental group known as the League to Save Lake Tahoe also filed suit. Both actions were filed in the Eastern District of California, and were assigned to Judge Edward J. Garcia. On May 1, 1984, Judge Garcia issued an Order to Show Cause and Temporary Restraining Order, which prohibited TRPA from issuing any permits in the Tahoe Basin, or even accepting any new applications for permits. Order to Show Cause and Temporary Restraining Order at 3, No. Civ. S-84-0561 EJG (E.D.Cal. May 1, 1984) (Defs.’ Ex. 300). The Order set a hearing date of May 31, 1984, for arguments regarding the issuance of a Preliminary Injunction. The hearing was eventually pushed back to June 11, but the Preliminary Injunction was granted-on June 15, 1984. People of State of Cal. ex rel. Van De Kamp v. Tahoe Reg’l Planning Agency, No. Civ. S-84-0561 EJG, 1984 WL 6591 (E.D.Cal. June 15, 1984) (Defs.’ Ex. 303). The court then issued its Order Granting Preliminary Injunction on August 9, 1984. Order Granting-Prelim. Inj., No. Civ. S-84-0565 EJG (E.D.Cal. Aug.9, 1984) (Defs.’ Ex. 314). The August 9 Order essentially adopted the terms of the T.R.O., except for the fact that a long list of specific exceptions (mostly for various government entities) was included. Eventually, the Preliminary Injunction was upheld by the Ninth Circuit. People of State of Cal. ex rel. Van de Kamp v. Tahoe Reg’l Planning Agency, 766 F.2d 1308 (9th Cir.1985). The injunction thus remained in force until a completely revised regional plan (the “1987 Plan”) was adopted in 1987. Also shortly after the 1984 Plan was adopted, on June 25, 1984, TRPA faced another legal challenge to the 1984 Plan-that is, the instant case. Or rather, cases. Originally, those plaintiffs owning property on the Nevada side of the Tahoe Basin filed suit in this Court, No. CV-N-84-257-ECR, and those plaintiffs owning property on the California side of the Basin filed an action in the Eastern District of California, which again was assigned to Judge Garcia, No. Civ. S-84-816 EJG. After proceeding separately for years, the California case was transferred to this Court, and the two actions were consolidated here. Order, No. CV-N-84-257-ECR (Feb. 21, 1992) (Doc. # 132). Initially, the complaints asserted claims against TRPA, the states of Nevada and California, and the individual members of TRPA’s Governing-Board, for declaratory and injunctive relief for due process and equal protection violations, and damages for violations of the takings clause. In addition, the complaint stated a claim for violations of the Civil Rights Act, 42 U.S.C. §§ 1983 and 1985, as well as what is commonly known as a “Furey” claim-that is, a claim that the plaintiffs had been forced to pay certain assessments on their land, but had not been able to enjoy the benefits of the public improvements those assessments funded (such as sewer service, etc.), since they were unable to build on their land. Furey v. City of Sacramento, 592 F.Supp. 463 (E.D.Cal.1984), aff'd, 780 F.2d 1448 (9th Cir.1986). Both in the complaints and throughout this litigation, the plaintiffs have been grouped by “class,” according to the land capability district of each plaintiffs land. “Class 1-3” plaintiffs and “SEZ” plaintiffs are grouped separately. Once the cases were consolidated, the plaintiffs were further grouped by state. Thus there are four groups of plaintiffs now before the Court: Nevada-side Class 1-3 plaintiffs; Nevada-side SEZ plaintiffs; California-side Class 1-3 plaintiffs; and California-side SEZ plaintiffs. The claims of these plaintiffs have also been divided-by time period, according to the effective dates of the various ordinances and other actions challenged herein: “Period I” covers August 24, 1981, to August 26, 1983; “Period II” covers August 27, 1983, to April 25, 1984; and “Period III” covers April 26, 1984, to July 1,1987. In the first round of district court decisions in the mid-1980s, both this Court and the Eastern District of California dismissed all of the plaintiffs’ claims. Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 611 F.Supp. 110 (D.Nev.1985); Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 638 F.Supp. 126 (D.Nev.1986); Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, Memorandum and Order, No. Civ. S-84-816 EJG (E.D.Cal. Jan. 22, 1985); Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, Memorandum of Decision and Order Granting Summ. J., No. Civ. S-84-816 EJG (E.D.Cal. Mar. 27, 1987). Both district courts were then reversed in part and affirmed in part by the Ninth Circuit. Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 911 F.2d 1331 (9th Cir.1990) (“TSPC I”) (reviewing the District of Nevada case); Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 938 F.2d 153 (9th Cir.1991) (“TSPC II”) (reviewing the Eastern District of California case). In TSPC I, the Ninth Circuit held that all claims for declaratory and injunctive relief were moot, as the 1984 Plan had been replaced in the interim by the 1987 Plan. Further, all claims for money damages against Nevada and California were dismissed on immunity grounds. The court followed these holdings in TSPC II. In the Nevada case, the Ninth Circuit held that all of the plaintiffs’ Period III takings and § 1983 claims against' TRPA were unripe, and that the Period I takings and § 1983 claims of the Class 1-3 plaintiffs against TRPA were also unripe. In the California case, however, the Ninth Circuit held that all of the plaintiffs’ takings and § 1983 claims against TRPA were ripe. On remand, the cases were consolidated in this Court. We allowed the plaintiffs to amend their complaints, and in doing so, the plaintiffs added claims against the 1987 Regional Plan. We again dismissed all of the plaintiffs’ claims: the Period I and Period II claims on statute of limitations grounds; the Period III claims for lack of causation; and the new claims against the 1987 Plan because they had not been properly joined, were unripe, and were time-barred. Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 808 F.Supp. 1474 (D.Nev.1992) (Nevada case); Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 808 F.Supp. 1484 (D.Nev.1992) (California case). In addition, we dismissed the Furey claims, which had been remanded to us for a determination of whether any assessments had been paid to TRPA (as opposed to other local agencies), because we found that no such payments had in fact been made to TRPA. Again, the Ninth Circuit reversed in part. Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 34 F.3d 753 (9th Cir.1994) (“TSPC III”), amended by 42 F.3d 1306 (9th Cir.1994). The court held that the plaintiffs’ takings claims as to Periods I and II were barred by the statute of limitations, but that their § 1983 claims as to the same periods were not time-barred. Further, the court held that the plaintiffs’ § 1983 claims as to the 1987 Plan were not barred by the 60-day statute of limitations contained in the Compact. Finally, the court remanded the plaintiffs’ Period III claims for the trier of fact to determine whether or not those claims were caused by the actions of TRPA. Subsequent to the most recent remand, we held that the plaintiffs’ § 1983 claims as to the 1987 Plan, while not barred by the 60-day Compact statute of limitations, were nonetheless barred by the appropriate § 1983 statutes of limitations in both Nevada and California. Tahoe-Sierra Preservation Council, Inc. v. Tahoe Reg’l Planning Agency, 992 F.Supp. 1218 (D.Nev.1998). Thus the recent trial, held December 1-16, 1998, only addressed the following claims: the Period I § 1983 claims of all the California plaintiffs, as well as of the Nevada SEZ plaintiffs; the Period II § 1983 claims of all the plaintiffs; and the Period III claims of the California plaintiffs. (Although by now it is clear that the plaintiffs could not bring separate “takings” claims apart from their § 1983 claims, as to the 1984 Plan both sets of claims are technically still in the case. Nonetheless, separate relief for the two sets of claims is not available.) Further, it should be noted that we had previously ordered the trial to be bifurcated into two phases: the first phase was to establish whether the plaintiffs were entitled to compensation for any of their claims; the second (to take place only if TRPA were found liable on any claims) was to determine how much compensation the plaintiffs were owed. The recent trial encompassed only the first phase. At trial, several witnesses testified as to the scientific basis for the findings, discussed above, that the increase in impervious land coverage in the Basin, especially in high hazard lands, causes a corresponding increase in sediment runoff into the lake, and the subsequent eutrophication thereof. The testimony of Dr. Goldman was especially persuasive. Dr. Goldman, one of the country’s leading limnologists, has been studying Lake Tahoe for almost forty years, and has personally recorded data regarding its loss of clarity. In general, we find the scientific evidence presented by the defendants to be credible. One area that was heavily contested at trial, however, involved the testimony of two expert witnesses, one called by each side, on the subject of appraising the value of high hazard lands during the period at issue, and whether a “competitive market” for such land existed between 1981-1987 or any portion thereof. Since the resolution of this question resolves one of the major issues in the case, we will discuss it in more detail together with our discussion of the legal questions involved, infra. CONCLUSIONS OF LAW I. REGULATORY TAKINGS All of the remaining claims in this case were brought under 42 U.S.C. § 1983, alleging violations of the Takings Clause of the Fifth Amendment to the United States Constitution. The Takings Clause provides as follows: “nor shall private property be taken for public use, without just compensation.” U.S. Const, amend. V. Of course, the Takings Clause is applicable to the States through the Fourteenth Amendment. Dolan v. City of Tigard, 512 U.S. 374, 383, 114 S.Ct. 2309, 129 L.Ed.2d 304 (1994). Technically speaking, TRPA is not a state or even a subdivision of a state-it is a separate legal entity, created by the Compact. Compact, Article 111(a). Nonetheless, TRPA is clearly liable for damages for such violations. TSPC I, 911 F.2d 1331, 1341 (9th Cir.1990). The Takings Clause can be violated either by direct government appropriation of property without just compensation, or by government regulation that interferes with a property owner’s use of her property to the extent that it accomplishes nearly the same result as a direct appropriation. Lucas v. South Carolina Coastal Council, 505 U.S. 1003, 1014, 112 S.Ct. 2886, 120 L.Ed.2d 798 (1992). “[WJhile property may be regulated to a certain extent, if regulation goes too far it will be recognized as a taking.” Pennsylvania Coal Co. v. Mahon, 260 U.S. 393, 415, 43 S.Ct. 158, 67 L.Ed. 322 (1922). A. Do TRPA’s Actions “Substantially Advance a Legitimate State Interest”? The instant case does not involve any allegations of direct appropriations of land by TRPA. All of the claims are of the “regulatory takings” variety. Government 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. Agins v. City of Tiburon, 447 U.S. 255, 260, 100 S.Ct. 2138, 65 L.Ed.2d 106 (1980). As to the first of these possibilities, there is as yet no clear test for determining whether a regulation substantially advances a legitimate state interest-at least in the type of situation involved here. First, though, it is clear that the “interest” being advanced must be “legitimate.” We suppose an argument could conceivably be made that preventing the eutrophication of Lake Tahoe is not a legitimate interest for the government to pursue at all, but no one in this case has made that argument. Nor do we think that such an argument would ever be successful. Besides the intrinsic value of preserving the environment from degradation and destruction, the beauty of Lake Tahoe is largely responsible for driving the economy of the region, which is based almost entirely on tourism. Thus the main question to be resolved here is not whether the state interest is “legitimate,” but whether TRPA’s actions “substantially advanced” that interest. The Supreme Court has developed a test to make this determination in its “unconstitutional exactions” cases, Dolan v. City of Ti-gard and Nollan v. California Coastal Comm’n-the “essential nexus”/“rough proportionality” test. That is, first it must be determined “whether the ‘essential nexus’ exists between the ‘legitimate state interest’ and the permit condition exacted by the city,” Dolan, 512 U.S. at 386, 114 S.Ct. 2309 (citing Nollan, 483 U.S. 825, 837, 107 S.Ct. 3141, 97 L.Ed.2d 677 (1987)), and then whether some “rough proportionality” exists between the condition exacted and the “impact of the proposed development.” Id. at 390-91, 114 S.Ct. 2309. Aside from one footnote in Dolan, these cases do not really indicate whether this test should also be applied to situations in which no concession is being sought by the government in return for the grant of a permit to a specific individual. The relevant footnote states only the following: while in regard to individualized, adjudicative, permit conditions the burden of proof is on the government, “in evaluating most generally applicable zoning regulations, the burden is on the party challenging the regulation to prove that it constitutes an arbitrary regulation of property rights.” Id. at 391 n. 8, 114 S.Ct. 2309. However, the Ninth Circuit has indicated that this test may not be limited to cases involving exactions. In Del Monte Dunes at Monterey, Ltd. v. City of Monterey, 95 F.3d 1422 (1996) (“Del Monte Dunes ”), reh’g granted, 118 F.3d 660, reh’g en banc denied, 127 F.3d 1149 (9th Cir.1997), cert. granted, — U.S. -, 118 S.Ct. 1359, 140 L.Ed.2d 509 (1998), the court applied the “rough proportionality test to a case in which nothing was exacted-the permit was simply denied. Id. at 1430 (holding that “[significant evidence supports Del Monte’s claim that the City’s actions were disproportional to both the nature and extent of the impact of the proposed development”). More recently, though, the court held that the Dolan/Nollan analytical framework does not apply at all to facial challenges such as this one. Garneau v. City of Seattle, 147 F.3d 802, 811 (9th Cir.1998). Unfortunately, however, there is no majority opinion in Garneau, so the case is of limited precedential value. If Garneau is correct, then the “rough proportionality” test would not apply here-but there is no indication of what other test should then be applied instead. Given that any other possible test would most likely be less stringent than the rough proportionality test (such as, perhaps, the Dolan footnote’s statement that the regulation must not be “arbitrary”), it seems clear that TRPA’s actions do “substantially ad-vanee a legitimate state interest.” For the actions in question satisfy even the rough proportionality test. The evidence is quite convincing that further development on high hazard lands such as the plaintiffs’ would lead to significant additional damage to the lake. Thus, limiting such development unquestionably satisfies the “essential nexus” part of the test. 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. Dolan, 512 U.S. at 391 n. 8, 114 S.Ct. 2309. 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. B. Do TRPA’s Actions Deny the Plaintiffs “Economically Viable Use” of Their Property? As the challenged actions of TRPA therefore clearly do “substantially advance legitimate state interests,” the question to be answered next is whether those actions deprived the plaintiffs of “economically viable use” of their property. If TRPA’s actions deprived the plaintiffs of all economically viable use of their land, as opposed to just some such use, then those actions would constitute what have been referred to as “categorical” takings, with no further inquiry necessary. Lucas, 505 U.S. at 1015, 112 S.Ct. 2886. On the other hand, if TRPA’s actions deprived the plaintiffs of some, but not all, economically viable use of their land, then TRPA’s actions must be analyzed under the “essentially ad hoc, factual inquir[y]” of Penn Central Transp. Co. v. City of New York, 438 U.S. 104, 124, 98 S.Ct. 2646, 57 L.Ed.2d 631 (1978) (“Penn Central”). Under the Penn Central test, a regulation may or may not effect a taking, depending on: (1) “the economic impact of the regulation on the claimant”; (2) “the extent to which the regulation has interfered with distinct, investment-backed expectations”; and (3) “the character of the governmental action.” Id. At least one of these “tests” will apply, however-that is, either the Lucas “categorical takings” rule, or the Penn Central ad hoc balancing test. In other words, it. is clear that TRPA’s actions did deny the plaintiffs at least some economically viable uses of their land. The question which remains to be answered-and which was hotly debated at trial-is whether the denial was total, or only partial. This question is important because the answer effectively decides the outcome of the case. 1. Did TRPA’s Actions Effect a “Partial Taking” of the Plaintiffs’ Property? If we were to hold that TRPA’s actions effected only a partial denial of economically viable use, then consideration of the Penn Central factors clearly leads to the conclusion that there was no taking. Given the temporary nature of the regulations at issue here, we cannot say that the plaintiffs’ reasonable, investment-backed expectations were unduly interfered with. Dodd v. Hood River County, 136 F.3d 1219, 1230 (9th Cir.), cert. denied, — U.S. -, 119 S.Ct. 278, 142 L.Ed.2d 229 (1998). Mr. Johnson, the defendants’ appraiser, testified that the average holding time of a lot in the Tahoe area between lot purchase and home construction is twenty-five years. If the average purchaser expects to hold a lot for twenty-five years before building on it, then a delay of six years in being able to build would not be an interference with that purchaser’s expectations at all. We recognize, of course, that some of the individual plaintiffs herein may conceivably have held their properties for almost twenty-five years by the time the restrictions on construction at issue were imposed, or may have intended to build immediately. We have no way of knowing this, since no information regarding any of the individual plaintiffs was presented at trial. Thus we must rely on testimony as to the “average” purchaser’s intent. Besides, the fact that some plaintiffs may have already held their property for a long period of time would not exactly weigh in their favor. It would certainly show that they did not intend to build immediately upon purchase. Further, they would have 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. The Tahoe area experienced a glut of construction in the years just before the Compact was amended in 1980, as worried property owners attempted to build while they still could. On the other hand, if some individual plaintiffs in this action acquired their property more recently than twenty-five years before the restrictions were imposed, then their expected holding time may not have been affected at all. The facts were somewhat similar in Dodd, in which the Ninth Circuit found that the plaintiffs’ reasonable, investment-backed expectations had not been interfered with. In Dodd, the plaintiffs had purchased land in 1984, but waited until 1990 to file for the necessary permit to build. For six more years, it appeared that no such permit would be granted, but in 1996 it was. However, the plaintiffs had still not commenced building by 1998, when the Ninth Circuit heard their case. The court found that the self-imposed delay in building their retirement home weighed heavily against the idea that their reasonable, investment-backed expectations had been foiled by the six-year delay they suffered as a result of the permit process. Dodd, 136 F.3d at 1230. Thus, we hold that, like the plaintiffs in Dodd, the plaintiffs in our case 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. This factor therefore weighs against a finding that TRPA’s action effected a partial taking of the plaintiffs’ property. The fact that no information on individual plaintiffs was introduced at trial also affects our ability to analyze the first of the Penn Central factors-that is, the economic impact of TRPA’s actions on the plaintiffs. Since the burden is on the plaintiffs to show that a taking occurred (and since that burden is especially heavy in a facial challenge such as this), the fact that they agreed not to introduce this type of evidence works against them. The fact that it is a facial challenge does not mean that all evidence relating to individual plaintiffs is irrelevant at this stage. See Gameau, 147 F.3d at 807-08 (engaging in “ad hoc, factual inquiry appropriate in non-categorical regulatory takings cases” in acknowledged “facial” case). It may be that the instant plaintiffs could have produced evidence of this type, but they clearly chose not to do so. We assume that this was a result of a calculated choice by plaintiffs’ counsel to concentrate on the plaintiffs’ main contention, that TRPA’s actions resulted in a categorical taking, and not a partial taking. Regardless, 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. The third of the Penn Central factors, that of “the character of the governmental action,” also weighs against a finding that there was a partial taking of the plaintiffs’ property. As discussed above, the scientific evidence convincingly shows that Lake Tahoe was losing its clarity due to increased development in the Basin, especially in high hazard lands. Thus limiting development on high hazard lands is a direct and reasonable way to combat the problem. Faced with the responsibility for solving a serious problem, TRPA took the necessary steps to do so. While those steps may have had a more substantial impact on the plaintiffs than on others in the Basin, the plaintiffs were not completely deprived of their land, and they retained many important rights of property ownership, such as the right to exclude others from their own land. See Penn Central, 438 U.S. at 124, 98 S.Ct. 2646 (“A ‘taking’ may more readily be found when the interference with property can be characterized as a physical invasion by government [citation omitted], than when interference arises from some public program adjusting the benefits and burdens of economic life to promote the common good.”). Thus with all three of the Penn Central factors, at least to some extent, weighing against a finding that TRPA’s actions constituted a partial taking, we clearly must hold that anything less than a total denial of all economically viable use of the plaintiffs’ property would not constitute a taking. Since the Penn Central test is essentially a balancing test-“a weighing of private and public interests,” Dodd, 136 F.3d at 1229 (citing Agins, 447 U.S. at 261, 100 S.Ct. 2138)-and since the interest in protecting Lake Tahoe is so strong, any test that takes that interest into account would result in victory for the defendants. However, if the plaintiffs were deprived of all economically viable use of their property, then the interest in protecting Lake Tahoe is not taken into account. No matter how noble the goal of protecting the lake, and no matter how necessary the steps taken were to achieving that goal, the plaintiffs would be entitled to just compensation from TRPA. “It is axiomatic that the Fifth Amendment’s just compensation provision 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.’ ” First English Evangelical Lutheran Church of Glendale v. Los Angeles County, 482 U.S. 304, 318-319, 107 S.Ct. 2378, 96 L.Ed.2d 250 (1987) (“First English ”) (quoting Armstrong v. United States, 364 U.S. 40, 49, 80 S.Ct. 1563, 4 L.Ed.2d 1554 (1960)). 2. Did TRPA’s Actions Effect a “Total Taking” of the Plaintiffs’ Property? The most important question we must decide, then, is whether the plaintiffs have indeed been deprived of all economically viable use of their land. Thus, we must first decide how to answer that question. At trial, the defendants argued, essentially, that property that has been deprived of all economically viable use will be rendered completely “valueless,” so that property with any remaining value, by definition, must have some remaining economically viable use. The plaintiffs, on the other hand, argued that the “value” of property is utterly irrelevant to the determination of whether any viable uses of that property remain, and even moved to exclude all evidence of value at trial. Pls.’ Mot. in Limine (Oct. 30, 1998) (Doc. # 289). Both of these contentions are meritless. “Value” is unquestionably relevant to the issue of whether there has been a taking. The Ninth Circuit explicitly recognized this in Del Monte Dunes, 95 F.3d at 1433. The only case to which the plaintiffs point for support of their argument that “value” is irrelevant is Lucas, which certainly does contain language stressing the importance of “use.” But Lucas clearly relied on the lower court’s finding that the regulations at issue had in fact rendered the plaintiffs property “valueless.” Lucas, 505 U.S. at 1020 n. 9, 112 S.Ct. 2886. Thus Lucas could just as easily be read to support the defendants’ contention that value is “everything” as the plaintiffs’ contention that value is “nothing .” In truth, however, Lucas supports neither of these extremes. It was clearly important to the Court that the property had been rendered “valueless”; likewise, however, it was also important that Lucas could not “use” his property in any “economically beneficial or productive” fashion. Lucas, 505 U.S. at 1015, 112 S.Ct. 2886. In any event, regardless of how Lucas could be read, the Ninth Circuit has essentially resolved the issue for us. In Del Monte Dunes, the court explicitly held that value, while clearly relevant, was not the main focus of the economically viable use inquiry. Del Monte Dunes, 95 F.3d at 1433. The court further held that proof that a property retains some value is not sufficient to prove that the property retains some economically viable use. Id. at 1432-33. This holding is key to our ease, because it is clear that the plaintiffs’ properties-no matter how restricted their use-did retain some value during the period at issue. The defendants’ appraiser, Mr. Johnson, testified to the fact that during the period at issue, some sales of Class 1-3 and SEZ properties did take place. Further, his testimony supports the proposition that all land in the Tahoe Basin has, and has always had, some value, no matter how limited its uses. In some instances that value may be minimal, but none of the land is completely “valueless,” as was the ease in Lucas. As we have seen, however, the fact that the land had some value is not sufficient. The land must retain some “economically beneficial or productive use.” Of course, there is some connection between the two concepts. To a large extent, land will only have significant value if there is some use to which it can be put-for as the Supreme Court has recognized, “[w]ha
