The trial court entered judgment in favor of plaintiffs against defendant. Defendant appeals the judgment, and we reverse and enter judgment in favor of defendant.
I. NATURE OF THE CASE
When a citizen claims that a governmental land-use regulation, or its regulatory implementation, adversely affects the value of his or her property, and seeks just compensation under the Taking Clause of the Fifth Amendment,1 our courts must decide whether the challenged governmental action, and its consequent effect on private property, constitutes a “regulatory taking” under federal and state taking jurisprudence.
More specifically, when, as here, the government regulates land use — as opposed to taking physical possession of land2 — and where, as here, the challenged [527] regulation is stipulated to be for the public good, our limited role is to answer the specific constitutional question: where implementation of a valid land use regulation3 negatively impacts a private citizen’s valuable property rights, does the Taking Clause require [528] compensation? To answer this question, our Supreme Court has instructed us to examine the United States Supreme Court’s seminal decision in Penn Central Transportation Co v New York, 438 US 104; 98 S Ct 2646; 57 L Ed 2d 631 (1978).4
The United States Supreme Court in Penn Central laid out a three-factor test for courts to apply to answer this important constitutional question:
[1] The economic impact of the regulation on the claimant and, particularly, [2] the extent to which the regulation has interfered with distinct investment-backed expectations are, of course, relevant considerations. So, too, is [3] the character of the governmental action. A “taking” may more readily be found when the interference with property can be characterized as a physical invasion by government than when interference arises from some public program adjusting the benefits and burdens of economic life to promote the common good. [Id. at 124 (citations omitted).]
The taking jurisprudence articulated by the United States Supreme Court in Penn Central and its progeny5 requires that our courts consider the following factors in deciding whether a “regulatory taking” claim is compensable: (1) what is the average reciprocity of advantage, in other words, is the aggrieved property owner singled out to pay for the public good, or is the land-use regulation so universal and ubiquitous that the benefits and burdens of the land-use regulation fall relatively equally among all, including the complaining [529] party; (2) what use could the landowner reasonably expect to make of the land given the state of the land-use regulations at the time of acquisition (as part of this inquiry, it is necessary to take into account whether the landowner knew, or should have known, of the land-use regulation at the time of purchase); and (3) did the specific, challenged application of the land-use regulation leave the property owner valuable land use rights or did it instead render the land virtually worthless?
Stated another way, if the land-use regulation, like traditional zoning and wetland regulations: (1) is comprehensive and universal so that the private property owner is relatively equally benefited and burdened by the challenged regulation as other similarly situated property owners, and (2) if the owner purchased with knowledge of the regulatory scheme so that it is fair to conclude that the cost to the owner factored in the effect of the regulations on the return on investment, and (3) if, despite the regulation, the owner can make valuable use of his or her land, then compensation is not required under Penn Central.
Here, plaintiffs claim that the denial by the Department of Environmental Quality (DEQ) of a permit to fill in the wetland on their property constitutes a regulatory taking. Wetland regulations are, like zoning regulations, all but ubiquitous. At the federal level, the Clean Water Act (CWA)6 provides for the regulation and protection of wetlands, while Michigan’s wetland protection act (WPA)7 serves the same purpose for this state. Our Legislature made clear that it enacted the WPA to benefit all the people of this state. The act provides that “[t]he legislature finds that. . . [w]etland [530] conservation is a matter of state concern since a wetland of 1 county may be affected by acts on a river, lake, stream, or wetland of other counties.” MCL 324.30302(1)(a).8
Clearly, all people, including property owners, are the intended beneficiaries of the regulation of wetlands. Like zoning regulations, wetland regulations place a burden on some property owners, but this burden ultimately benefits all property owners, including those who claim they are unfairly burdened.
As we will discuss in detail later, we reject plaintiffs claim because (1) wetland regulations are, much like [531] zoning regulations, comprehensive, universal, and ubiquitous, and provide an “average reciprocity of advantage” for all property owners, including plaintiffs; (2) plaintiffs have developed and retain the ability to develop a significant amount of their property, and thus plaintiffs’ property retains a significant value even after the permit denial; and (3) plaintiffs are experienced commercial land developers who clearly had or were on notice of the wetland regulations promulgated under the WPA, and, therefore, plaintiffs’ distinct, investment-backed expectations would reasonably have been tempered with the knowledge that their development of the property would be restricted because of the presence of wetlands.
II. FACTS AND PROCEDURAL HISTORY
A. PROCEDURAL HISTORY
This case was originally filed in the Court of Claims on December 29, 1988. Plaintiffs, K & K Construction, Inc., the J.EK. Company, and Resorts and Company, alleged that defendant, then the Michigan Department of Natural Resources (DNR) (currently the Department of Environmental Quality),9 had effected a regulatory taking of plaintiffs’ property when it designated part of that property as wetland and denied a permit to fill in the wetland and build on the property. Following a nonjury trial, the trial court entered judgment in favor of plaintiffs. The trial court found that the DEQ’s failure to issue the requested permit constituted a categorical taking of plaintiffs’ property.
[532] The DEQ appealed to this Court, which, as it turns out, erroneously affirmed the trial court’s judgment. K & K Constr, Inc v Dep’t of Natural Resources, 217 Mich App 56; 551 NW2d 413 (1996) (K & K I), rev’d 456 Mich 570 (1998). The DEQ then appealed to our Supreme Court, which reversed this Court’s decision and the trial court’s judgment. K & K Constr, Inc v Dep’t of Natural Resources, 456 Mich 570; 575 NW2d 531 (1998) (K & K II). Our Supreme Court held that (1) the trial court erred when it considered only the parcel of land that contained wetland (parcel one) and did not include two other contiguous parcels of land owned by plaintiffs (parcels two and four) and (2) plaintiffs were not deprived of all economic use of the land and thus there was no “categorical taking.” Id. at 586. Further, our Supreme Court remanded to the trial court with instructions (1) to include the value of the two other parcels, (2) to make a finding of fact regarding whether a third parcel (parcel three) should be included in the value, and (3) to apply the balancing test articulated by the United States Supreme Court in Penn Central to determine whether plaintiffs proved their regulatory taking claim. K&K II at 588.
On remand, plaintiffs J.F.K. Company and Resorts and Company were succeeded by J.F.K. Investment Co, LLC (JFK). The parties stipulated that parcel four was not to be included in the trial court’s determination, and the trial court held that parcel three would be included with parcels one and two when it determined whether a taking had occurred because of the wetland regulation. The trial court then held that under Penn Central, a taking had occurred and entered judgment in favor of plaintiffs.
The DEQ once again has appealed to this Court, and plaintiffs have cross-appealed.
[533] B. FACTUAL HISTORY
1. OVERVIEW
This case involves four contiguous parcels of land with a total area of approximately eighty-two acres in Waterford Township in Oakland County (parcels one through four). In 1988, a partnership was formed between J.EK. Company and Resorts and Company, with each holding a fifty percent interest, for the purpose of developing the land in issue.10 At some point, plaintiff J.F.K. Investment Company, LLC, replaced J.F.K. Company and Resorts and Company as a successor in interest. Plaintiff K & K Construction is a Michigan corporation in which Kosik owns fifty percent of the shares of stock.11
[534] Parcel one is zoned for commercial use, consists of approximately fifty-five acres, and approximately twenty-seven of those acres are wetland. Parcel two consists of sixteen acres directly south of parcel one and has a small area of wetland. Parcel three is 9.34 acres of land directly south of parcel two, with no wetland. Parcel four is 3.4 acres of land bordering the south side of parcel one and the east side of parcel two, and it has no wetland. Parcels two, three, and four are zoned for multiple-family housing. The parcels are bounded by Highland Road (M-59) on the north, North Oakland Drive on the east, Hospital Road on the west, and Pontiac Lake Road on the south.
Plaintiffs began work on a “C. J. Barrymore’s Restaurant” in 1988, which was to occupy forty-two acres on parcel one and to consist of a restaurant and a sports complex, including a baseball diamond. Waterford Township issued plaintiffs a cease-and-desist letter that stated that part of parcel one contained wetland and that plaintiffs would need to get a permit from the DEQ. Plaintiffs then filed a permit application with the DEQ dated May 28, 1988, which was received by the DEQ on June 21, 1988. On June 7, 1988, plaintiffs filed an “administrative complaint” with the DEQ and sought a ruling from the department that would remove a “designation of wetland” from plaintiffs’ property. Waterford Township sent a letter to plaintiffs informing them that their permit for lowland filling would be denied pending the outcome of the DEQ permit process. In November 1988, the DEQ issued a letter that denied plaintiffs’ permit application.12 Plaintiffs filed this ac[535] tion in December 1988.13
In May 1990, plaintiffs filed another application for a permit, under what is called the “Goga Plan.”14 The Goga Plan would have allowed plaintiffs to fill three acres of wetland, convert five acres of “upland” property to wetland, and develop the upland ring around the wetland. This permit application was also denied. At some point, both an office building for J.F.K. Investment Company and a Ram’s Horn Restaurant were built on upland portions of parcel one.15
This matter was originally tried in December 1991, and the only issue before the trial court was whether the permit denials constituted a taking of plaintiffs’ property. The trial court held that only parcel one was relevant to its analysis of whether a taking had occurred and concluded that the permit denials had rendered the parcel, which was worth approximately $6 million before the permit denial, completely worthless after the denial. Having found a categorical taking, the trial court ordered the DEQ to compensate plaintiffs for this $6 million loss in value.
[536] After the trial court’s ruling, the DEQ opted to mitigate the loss under MCL 324.30323, which requires a trial court to give the DEQ the option, once a taking has been found, to mitigate its damages by doing one of the following: compensate the property owner for the lost value, purchase the property, or “[m]odify its action or inaction with respect to the property so as to minimize the detrimental affect [sic] to the property’s value” (emphasis added).16 The DEQ chose to reverse its previous decision and issue the Goga permit. The trial court entered judgment in favor of plaintiffs against the DEQ for a “temporary taking”17 of the land that was [537] subsequently allowed to be developed under the Goga Plan for the full value of the wetland on parcel one. The judgment was for approximately $450,000 plus interest for the alleged temporary taking, and approximately $3.25 million plus interest for the alleged wetland taking. At the original trial, the trial court took into account the mitigating effect of the DEQ’s issuance of the Goga permit when it calculated the amount of the judgment.
The DEQ appealed the trial court’s ruling to this Court. Another panel of this Court affirmed the trial court’s judgment and agreed with the trial court that plaintiffs had been denied all economically beneficial use of their land, which resulted in a categorical taking. Our Supreme Court reversed, and reasoned (1) that the trial court erred in only considering parcel one and in not including parcels two and four in its valuation of plaintiffs’ property,18 and (2) in considering parcels one, two, and four, “it is clear that there was not a categorical taking. . . .”19 The Court then remanded to the trial court, and instructed it to calculate the total value of the property using parcels one, two, and four, and to make a finding regarding whether parcel three should be considered part of the “denominator parcel.” Additionally, the Court held that, while the record was not clear regarding whether the trial court had failed to include the value of the two developed portions of parcel one in its valuation, there was no reason for the trial court not to do so. The Court then held that, once the trial court determined whether parcel three should also be included, and the total value including all relevant parcels (either parcels one, two, and four, or all four parcels) was calculated, the trial court was to apply the [538] three-part balancing test from Penn Central to determine whether the DEQ’s administrative decision had constituted a regulatory taking.20 After plaintiffs’ unsuccessful petition for certiorari in the United States Supreme Court, the case returned to the trial court.21
Unsurprisingly, during trial, plaintiffs and the DEQ offered conflicting deposition testimony relating to the value of the property. At the first trial, plaintiffs presented the testimony of Edward Cheyz, who is not a licensed real estate appraiser. He testified that parcél one was valued at approximately $5.94 million before the denial of the permit. The trial court accepted this figure while rejecting the testimony of the DEQ’s appraiser. As discussed previously, the trial court found the value of these parcels to be zero after the first trial. On remand, plaintiffs offered the deposition testimony of James Mawson, a licensed appraiser, who initially testified that the pre-denial value of $5.94 million calculated by Cheyz was correct. This figure apparently represented a figure of $1.50 per square foot used by Cheyz in calculating the total value. However, on cross-examination, Mawson testified that he did not believe that Cheyz would be correct in valuing wetland at $1.50 per square foot and that a more appropriate figure might be $0.05 per square foot of wetland.
[539] On the other hand, the DEQ offered its own expert testimony and evidence in an attempt to show that the property’s “before” value had been overestimated and that its “after” value had been grossly underestimated. The DEQ also submitted evidence that, contrary to plaintiffs’ arguments that the non-wetland (upland) portion of parcel one was too shallow for development, other similar “shallow” lots had been developed in the area.
Regardless, the trial court, in its opinion and order issued after the second trial, stated incorrectly that, because our Supreme Court “did not disturb” its initial valuation of parcel one, it would reaffirm that value, and the trial court again concluded that parcel one had no value after the denial of the permit. The trial court did so despite the fact that our Supreme Court held that a categorical taking22 had not occurred. K&KII, supra at 585-587. Furthermore, the trial court reaffirmed its finding that parcel one had zero value despite the existence of the Ram’s Horn and the JFK office building, and despite the fact that our Supreme Court stated that it saw “no reason for [the office building and the Ram’s Horn] to be excluded from the taking analysis. They were both part of parcel one ... and neither was sold or developed before the enactment of the regulations in question.” K&KII, supra at 584 n 9. It further concluded that the value of parcels two and three, which totaled over $3 million, was not enough to offset this loss, and that the total value before the denial was just over $9 million, while the value after the denial was just over $3 million, representing a sixty-seven percent [540] loss. The trial court then briefly addressed each of the three Penn Central factors before concluding again that the DEQ’s permit denial constituted a taking. The trial court’s opinion stated that it would reaffirm its previous award.
At a hearing on plaintiffs’ posttrial motion for entry of judgment, the trial court found that the DEQ’s issuance of the Goga permit had not been a valid or effective way of mitigating its damages as required by MCL 324.30323 and entered judgment in September 2002 against the DEQ in the amount of $16,486,228, which included compensation for a taking of plaintiffs’ property in the amount of $5.9 million, the value the trial court allocated to parcel one, together with interest, costs, and attorney fees. The judgment further imposed interest on the entire judgment, including fees and costs.
Plaintiffs moved the trial court to reconsider the judgment rate of interest. They argued23 that the statutory rate of interest was insufficient, because plaintiffs were experienced real estate developers who could easily earn several times greater returns on their investment. The trial court rejected this argument and denied plaintiffs’ motion for a greater rate of interest. Plaintiffs have filed a cross-appeal to challenge the denial of this motion.
2. DAMAGES AND THE GOGA PERMIT24
After the first trial, the DEQ faced a judgment in excess of $6 million for what the trial court wrongly [541] held to be a categorical taking of plaintiffs’ property. As permitted by statute, MCL 324.30323, the DEQ decided to mitigate these damages and opted to issue the Goga permit pursuant to the permit application submitted by plaintiffs. The trial court then issued a written opinion that acknowledged that the DEQ’s election of this option had reduced the amount of. the taking award to approximately $3.25 million.25 The trial court additionally awarded approximately $450,000 for the temporary taking of plaintiffs’ property up to the issuance of the Goga permit.
However, plaintiffs did not build on parcel one as they were entitled to do pursuant to the Goga permit.26 Instead, plaintiffs insisted that the DEQ’s appeal of the nearly $4 million judgment against it also constituted an appeal of the permit and that the DEQ intended to revoke the permit if it prevailed on appeal. The DEQ sent plaintiffs a letter in which it stated that it did not believe that there should have been a judgment entered against the DEQ, and, therefore, that there should not have been damages assessed that the DEQ needed to mitigate by issuing the Goga permit. More importantly, however, the DEQ stated that the permit was valid and could be used by plaintiffs to begin development of parcel one. Yet plaintiffs continued in their assertion that the permit was subject to revocation because of the DEQ’s appeal.
As stated above, after this Court heard this case, and after our Supreme Court reversed the decisions of the [542] trial court and this Court, the case returned to the trial court after the United States Supreme Court denied a writ of certiorari. In the meantime, the Goga permit expired. After the case returned to the trial court in 1999, plaintiffs attempted to amend their complaint to raise claims in relation to the Goga permit and their claim that the permit was essentially an empty gesture. And the trial court originally, correctly, rejected plaintiffs’ argument and stated that plaintiffs could not raise new claims centered on the DEQ’s alleged failure to comply with the trial court’s judgment. The trial court said that, instead of waiting six years to try and bring new claims, plaintiffs should have gone before the trial court to address the alleged noncompliance.
Notwithstanding plaintiffs’ attempt to mischaracterize their rights and the DEQ’s conduct regarding the Goga permit, the DEQ reissued the expired Goga permit for five years. Nonetheless, plaintiffs continued to insist that the Goga permit was essentially worthless because the DEQ could revoke it if it prevailed on appeal. Plaintiffs made this assertion despite yet another letter from the DEQ in which it was stated that the DEQ had no intention of revoking the permit regardless of the outcome of the case.27 Instead of developing the land as they clearly could have under the newly reissued permit, plaintiffs continued to maintain that the Goga permit was an empty gesture. On the other hand, the DEQ maintains that plaintiffs’ actions are not motivated by a fear that the Goga permit might be revoked as much as they are by a desire to continue to accrue damages related to the alleged inability to develop their land.
[543] After the second trial, the trial court reversed its initial decision and agreed with plaintiffs regarding the Goga permit. The trial court issued a brief opinion in which it stated that it essentially was reaffirming its first judgment. After the trial court issued its opinion, plaintiffs moved for the entry of an order of judgment that included an award for the full value of parcel one. During a hearing on the motion, the DEQ reminded the trial court of the reissuance of the Goga permit and asked the trial court to take this into account, pursuant to MCL 324.30323, when it entered judgment, as the court had done after the first trial. However, this time, the trial court erroneously refused to take the Goga permit into account. Indeed, during the hearing, the trial court stated, in response to the DEQ’s request, that it “[found] the state’s handling of the Goga permit personally offensive.”
Ultimately, the trial court entered judgment in the amount of the entire value of parcel one, approximately $5.94 million, plus interest, costs, and attorney fees, which resulted in a total judgment in excess of $16 million, with additional interest payable from the date of judgment at the statutory rate. On appeal, plaintiffs continue to assert that the Goga permit’s issuance by the DEQ was a hollow gesture that did not, in reality, mitigate any damages, while the DEQ insists that plaintiffs’ claims that the permit is ineffective constitute a pretense for an attempt to accrue further damages.
III. STANDARDS OF REVIEW
We review a trial court’s findings of fact for a clear error and disturb the trial court’s findings only where we are “left with the definite and firm conviction that a [544] mistake has been made.” Essexville v Carrollton Concrete Mix, Inc, 259 Mich App 257, 265; 673 NW2d 815 (2003).28
Whether the government has effected a taking of one’s property is a constitutional issue, US Const, Am V; Const 1963, art 10, § 2, which we review de novo. People v Cain, 238 Mich App 95, 111; 605 NW2d 28 (1999).
IV ANALYSIS
A. TRIAL COURT’S COMPLIANCE WITH THE SUPREME COURT’S REMAND ORDER
The DEQ correctly asserts that the trial court disregarded the specific remand instructions of our Supreme Court. “ ‘The power of the lower court on remand is to take such action as law and justice may require so long as it is not inconsistent with the judgment of the appellate court.’ ” People v Fisher, 449 Mich 441, 446-447; 537 NW2d 577 (1995) (citations omitted); Waatti & Sons Electric Co v Dehko, 249 Mich App 641, 646; 644 NW2d 383 (2002). When an appellate court remands a case without instructions, a lower court has the “same power as if it made the ruling itself.” Fisher, supra at 447. However, when an appellate court gives clear instructions in its remand order, it is improper for a lower court to exceed the scope of the order. Waati & Sons, supra at 646. “It is the duty of the lower court or [545] tribunal, on remand, to comply strictly with the mandate of the appellate court.” Rodriguez v Gen Motors Corp (On Remand), 204 Mich App 509, 514; 516 NW2d 105 (1994).
1. THE TRIAL COURT’S FINDINGS OF FACT ON REMAND REGARDING THE VALUE OF THE DENOMINATOR PARCEL
During the first trial, the trial court considered only the value of parcel one in making its decision whether the DEQ’s denial of a wetland permit constituted a taking. The trial court held that the DEQ’s action deprived parcel one of all its economic value and that the DEQ had taken plaintiffs’ property. Our Supreme Court, however, held, consistently with Lucas v South Carolina Coastal Council, 505 US 1003; 112 S Ct 2886; 120 L Ed 2d 798 (1992), that a categorical taking had not occurred. K & K II, supra at 585-587. The Court then remanded the case to the trial court and clearly directed the trial court to make a new finding of fact with respect to the value of plaintiffs’ property and to include parcel two with parcel one when doing so. Furthermore, the trial court was clearly directed to make a finding of fact regarding whether parcel three should also be included in its analysis. Id. at 588. After the trial court made these new findings of fact, the trial court was to apply the three Penn Central factors, as mandated by our Supreme Court, to determine whether the DEQ’s action here constituted a taking.
Unfortunately, on remand, the trial court failed to adhere to the Supreme Court’s mandates. The trial court did make a finding of fact that parcel three should be included in its analysis during the new trial. Furthermore, the trial court purportedly considered parcels one, two, and three together in its analysis, as our Supreme Court’s decision required. However, the court [546] rationalized its ruling by contending that our Supreme Court had not specifically disturbed its valuation of plaintiffs’ property before and after the permit denial, simply reaffirmed its finding that the value of parcel one had diminished from nearly $6 million to zero. The court did this despite the fact that our Supreme Court essentially foreclosed any possibility of a finding that parcel one had a value of zero:
Even if we did limit our analysis to parcel one, the Court of Appeals conclusion that a categorical taking had occurred is not supported by the record. In its first opinion, the trial court stated: “While it is true that some financial value will remain, this Court finds that what little economic value remains is but a small fraction of the economic value the property would have had if all of it could be developed.” (Emphasis added.) Thus, while the regulations may have diminished the value of plaintiffs’ land, this diminution in value would not give rise to a categorical taking. ... [K & K II, supra at 587 n 13 (emphasis in the original).]
After a careful review of the trial proceedings, it is clear that the trial court failed to include the values of a Ram’s Horn Restaurant and plaintiff JFK’s office building, both located on upland portions of parcel one. Our Supreme Court stated that it saw “no reason for [the office building and the restaurant] to be excluded from the taking analysis. They were both part of parcel one as originally purchased, and neither was sold or developed before the enactment of the regulations in question.” Id. at 584 n 9. The evidence presented during the trial after remand shows that the Ram’s Horn and the JFK office building have a combined value of at least $1 million. Furthermore, our Supreme Court explicitly stated that “plaintiffs were not prohibited from developing the remaining upland on parcel one ....” K & K II, supra at 587. Were the trial court to have complied [547] with our Supreme Court’s remand instructions, the trial court could not reasonably have reaffirmed its previous finding that the value of parcel one had been reduced to zero. For this reason alone, the trial court’s holding must be reversed.
Additionally, the trial court then found that parcels two and three had a value of approximately $3 million. The trial court reasoned that this value was not high enough to “offset” the diminution in value that the court ruled parcel one had sustained. While the trial court held that the value of the entire “denominator parcel,” consisting of parcels one, two, and three, had been diminished in value by sixty-seven percent, from approximately $9 million to just over $3 minion, the trial court’s analysis here centered on the value of parcel one. Rather than treating the three parcels as a single denominator parcel as our Supreme Court mandated, the trial court erroneously continued to treat parcel one as the relevant parcel, and only considered the values of parcels two and three to the extent that they might “offset” the diminution in the value of parcel one. This directly contradicts our Supreme Court’s holding that any taking analysis here must look beyond the value of parcel one, and include the value of the entire denominator parcel. Accordingly, we conclude that the trial court did not comply with our Supreme Court’s remand instructions with respect to determining the value of the denominator parcel. Because we so conclude, we hold that the trial court’s findings of fact with respect to the value of the denominator parcel are clearly erroneous, and its decision is reversed.
2. COMPLIANCE WITH THE SUPREME COURT’S ORDER TO APPLY THE FACTS TO PENN CENTRAL
The trial court’s Penn Central analysis also failed to comply with the Supreme Court’s remand instruc[548] tions.29 A trial court must “comply strictly” with our Supreme Court’s mandate. Rodriguez, supra at 514. Here, the trial court, without an explanation of what the factors mean, and, indeed, without so much as a [549] citation of Penn Central, devoted not much more than a page of its analysis to this difficult, crucial, and dispositive analysis that was clearly mandated by our Supreme Court’s remand order. Moreover, and dispositively, the trial court’s ruling simply failed to properly apply the law to the facts.
For these reasons and reasons we will discuss in greater detail below, we hold that the trial court did not comply with our Supreme Court’s remand instructions with respect to its purported Penn Central analysis.
3. THE GOGA PERMIT AND MITIGATION
As outlined above, our Legislature, following the lead of the United States Congress, passed comprehensive legislation to protect Michigan’s wetlands for the benefit of its citizens. This represents a clear public policy determination and statement of the importance to the citizens of this state, including property owners, of preserving wetlands for public welfare. MCL 324.30302. Moreover, the Michigan Constitution provides that “[t]he legislature shall provide for the protection of the air, water and other natural resources of this state ... .” Const 1963, art 4, § 52. In keeping with this mandate, the Legislature enacted the Natural Resources and Environmental Protection Act (NREPA), MCL 324.101 et seq., which contains the WPA. The Legislature vests the DEQ with the responsibility for guarding our state’s valuable natural resources on behalf of the citizens of this state. MCL 324.501.
In keeping with this constitutional and statutory scheme, our Legislature also expressed its intent that the DEQ should act to preserve public funds as well as public resources by establishing a statutory framework to mitigate damages to the state should a court find that the DEQ “went too far” in implementing the wetland [550] regulations in a particular case. MCL 324.30323(3) represents our Legislature’s well-considered plan to serve the dual purpose of having the DEQ protect the environment while also protecting the pocketbooks of our citizens by creating a mechanism to mitigate damages in those cases where courts find that the DEQ may have gone too far. Here, the DEQ, as our Legislature envisioned, acted properly under the statute to mitigate damages. The trial court should not have disregarded this legislative mandate where the DEQ, acting to preserve the citizens’ financial resources, agreed to an alternative use of the land, as proposed by plaintiffs, that would have allowed substantial development of the property at issue.
The courts of this state must recognize that our constitutionally and statutorily mandated agencies, like the DEQ, have a difficult duty in administering complex laws to preserve the environment for all citizens while respecting the important private property rights of those directly affected by the regulations. Our Legislature clearly saw the wisdom of anticipating that, in balancing these competing, important interests, the DEQ might err, at least in the judgment of a judge who is asked to review a specific application of the wetland regulations to a specific piece of property. And, when a judge rules against the DEQ, the state agency has the further task of again deciding how best to preserve taxpayer dollars and the environment by choosing the legislative options of purchasing the property, paying the amount of the lost economic value, or taking some other action, such as the issuance of an alternative permit that allows greater development, but with minimal damage to wetlands. Our courts should not ignore this complex, important statutory mitigation scheme. This legislative mandate is an important application of constitutional, statutory, and administrative law that [551] must be respected and administered by our courts in the best interests of the public. This, the trial court simply failed to do. The statute does not allow a trial court to deny the state a chance to mitigate a regulatory taking judgment on the basis of the trial court’s views of the DEQ.
Moreover, we agree with the trial court’s original ruling with respect to the Goga permit, and further hold that plaintiffs waived this claim that the DEQ’s appeal rendered the Goga permit invalid. If plaintiffs truly believed that the DEQ disobeyed that portion of the trial court’s original order regarding the Goga permit, then plaintiffs should have sought the appropriate relief. Our review of the record reveals no attempt by plaintiffs to seek declaratory or other relief with respect to the Goga permit. Any claim that the DEQ’s appeal rendered the Goga permit invalid here was waived by plaintiffs’ own conduct.30 Lewis v LeGrow, 258 Mich App 175, 210; 670 NW2d 675 (2003) (“[E]rror requiring reversal may only be predicated on the trial court’s actions and not upon alleged error to which the aggrieved party contributed by plan or negligence.”).
B. THE PENN CENTRAL FACTORS AS APPLIED TO THIS CASE
In Penn Central, the United States Supreme Court noted that “[t]he question of what constitutes a ‘taking’ ... has proved to be a problem of considerable difficulty.” Penn Central, supra at 123. The constitutional requirement that the state provide just compensation for the taking of one’s property is “ ‘designed to bar Government from forcing some people alone to bear public [552] burdens which, in all fairness and justice, should be borne by the public as a whole.’ ” Id. at 123-124, quoting Armstrong v United States, 364 US 40, 49; 80 S Ct 1563; 4 L Ed 2d 1554 (1960). The Court stated that taking determinations are “essentially ad hoc, factual inquiries . . . .” Penn Central, supra at 124.
Since the United States Supreme Court’s decision in Penn Central, and, indeed, since our Supreme Court’s decision in K & KII, the United States Supreme Court has farther explained its holding in Penn Central. A governmental regulation that deprives a landowner of “all economically beneficial use” of his or her property is a categorical taking that requires compensation. Palazzolo v Rhode Island, 533 US 606, 615-616; 121 S Ct 2448; 150 L Ed 2d 592 (2001), citing Lucas, supra. Here, our Supreme Court rejected the trial court’s ruling that the DEQ had effected a categorical taking of plaintiffs’ property and remanded the case to the trial court with the instruction to determine, pursuant to Penn Central, whether a taking had occurred despite the fact that plaintiffs’ property had some, but because of the trial court’s error, a yet to be determined, remaining value. The United States Supreme Court in Penn Central identified three factors to be examined when a court makes such a determination:
[1] The economic impact of the regulation on the claimant and, particularly, [2] the extent to which the regulation has interfered with distinct investment-backed expectations are, of course, relevant considerations. So, too, is [3] the character of the governmental action. A “taking” may more readily be found when the interference with property can be characterized as a physical invasion by government than when interference arises from some public program adjusting the benefits and burdens of economic life to promote the common good. [Penn Central, supra at 124 (citations omitted).]
[553] As we will discuss in greater detail below, while no one of the three factors is dispositive in and of itself, a key factor in terms of wetland regulations is the third, the character of the government action. Where, as here, the regulation serves an important public interest and is widespread and ubiquitous, we conclude that, to sustain a regulatory taking claim, a plaintiff must prove that the economic impact and the extent to which the regulation has interfered with distinct investment-backed expectations are the functional equivalent of a physical invasion by the government of the property in question.
1. ECONOMIC IMPACT OF THE REGULATION
A reduction in the value of the regulated property is insufficient, standing alone, to establish a compensable regulatory taking. Penn Central, supra at 131. Indeed, the Supreme Court in Penn Central cited two of its previous opinions in which the Court refused to hold that there was a regulatory taking: Euclid v Ambler Realty Co, 272 US 365; 47 S Ct 114; 71 L Ed 303 (1926), in which a zoning regulation resulted in a seventy-five percent diminution in value, and Hadacheck v Sebastian, 239 US 394; 36 S Ct 143; 60 L Ed 348 (1915), in which the regulation resulted in an 87.5 percent diminution.
Here, the DEQ’s initial refusal to grant the requested permit unquestionably caused some decrease in the value of the property. After the second trial, the trial court held, erroneously, that the value had declined from a value before the denial of the permit of approximately $8.94 million to a value after denial of approximately $3 million, which represents a diminution of value of approximately sixty-seven percent. Even under this incorrect, inflated “damage calculation,” plaintiffs [554] failed to demonstrate a sufficient decrease in value to constitute a compensable regulatory taking under Penn Central, Euclid, and Hadacheck.
