Old Tuckaway Associates, a limited partnership, and Affiliated Capital Corp. (collectively, Tuckaway), appeal from a final judgment *261entered in favor of the City of Greenfield (City) and the City of Greenfield Board of Zoning Appeals.

Tuckaway presents the following issues for review: (1) whether the trial court, in its court-trial decision, erred in denying Tuckaway's claims that the City's actions, overall, deprived Tuckaway of property and liberty without due process of law; (2) whether the trial court, following a certiorari review, erred in concluding that the Board of Zoning Appeals properly denied Tuckaway's appeal from the City's rejection of a petition for an amended Planned Unit Development (PUD); and (3) whether the trial court, in its summary judgment determinations, erred in granting judgment in favor of the City on Tuckaway's claims for inverse condemnation, breach of contract and tortious interference with a contract. We affirm.

I. BACKGROUND

This action arises out of a land use regulation dispute. In 1967, the management of the Tuckaway Country Club golf course decided to relocate the golf course from Greenfield to Franklin. In an effort to defray the costs of the new facility in Franklin, the Country Club sold the newly vacant land in Greenfield to a group of investors known as Tuckaway Club Enterprises. Shortly thereafter, Tuckaway Club Enterprises and the City of Greenfield executed a Declaration of Restrictions (Declaration) pursuant to which various zoning, density and use limitations were placed on the property. The Declaration effectively established a *262Planned Unit Development (PUD)1 that permitted the flexible development of the former golf course land.

*263Over the years, Tuckaway Club Enterprises selectively developed portions of the land that had once been the golf course. By 1987, only thirty-two acres of the property remained undeveloped. Tuckaway, the plaintiffs in the present action, expressed interest in purchasing these thirty-two acres from Tuckaway Club Enterprises for development purposes. Land use restrictions applying to portions of the thirty-two-acre tract by virtue of the 1967 Declaration, however, made development unattractive.2 Thus, Tuckaway's eventual agreement to purchase the property was contingent on the ability of Tuckaway Club Enterprises to persuade the City to amend the Declaration to a more amenable classification, i.e., a classification *264that allowed a reasonable density of units per acre throughout the entire tract of land.

On November 6, 1987, following discussions with surrounding neighbors concerning the flow of vehicular traffic, Tuckaway agreed to construct a new road on the property in an attempt to alleviate residents' concerns. Following this offer, the City executed an Amendment to the Declaration of Restrictions (Amendment). The Amendment provided, in part, that the thirty-two-acre parcel would be zoned PUD with residential uses and that the density of dwelling units on the property could not exceed seventeen units per acre. The Amendment further provided that it "is complimentary to the Planned Development Ordinance of the City and that the development hereinabove described is subject to the ordinance." After the Amendment was recorded, Tuckaway completed the purchase of the thirty-two-acre tract from Tuckaway Club Enterprises.

In 1989, Tuckaway decided to sell approximately five acres of the property rather than develop it themselves. Consequently, on July 12, 1989, Tuckaway executed an Offer to Purchase with David Morgenson, a private developer, for approximately five acres of the thirty-two-acre tract. Morgenson intended to develop the five-acre tract with residential dwellings. The Offer to Purchase was subject to the following condition:

This Offer is contingent upon the Buyer obtaining the necessary zoning and building permits from the City of Greenfield and the State of Wisconsin and all other governmental regulatory agencies having jurisdiction to permit the construction of at least 83 residential rental units acceptable to Buyer in at least 2-3 separate residential buildings with separate tax bills on these parcels within 90 days from *265August 15, 1989 or this Offer will be deemed null and void.

Subsequently, Morgenson and his associate in development,- Joseph Gallina, prepared plans for the construction of eight ten-unit buildings (the "Project"). On October 10, 1989, Gallina petitioned the Planning Commission for approval of the Project. Concerned citizens at the meeting expressed objections to the Project, particularly because of the density of the Project and the developer's intention to rent a portion of the units. The meeting was adjourned without Project approval.

Over the next four months, Gallina appeared before the Planning Commission on several occasions. At each of these meetings, the issue of density and/or rentals was of great concern to the neighbors surrounding the proposed development. In response to the issue of density, the City obtained two legal opinions which concluded that the proposed density did not violate any City ordinances. The City also received an opinion from its attorney that once the Project was completed, the City would have no legal authority to prevent the owners from renting the units.

On January 30, 1990, the Planning Commission considered Gallina's petition for an amendment to the Declaration. After listening to the legal opinions concerning density, and following some discussion by Alderman Snyder regarding a discrepancy in the way the "mean density" figure was calculated, the Planning Commission, on a motion by Alderman Waite, recommended' that the Common Council reject Gallina's petition for an amendment. The motion carried by a four-to-one vote.

On February 13, 1990, the Planning Commission voted to reconsider its January 30 action. Alderman Waite noted that his motion of January 30 was improp*266erly based upon density and mean number. He further stated that his true intent was that the amendment should be denied based on the fact that it was a major change to the existing PUD. Alderman Waite then presented a motion that the Common Council deny "the request to amend the Tuckaway Plan Unit Development Agreement for the Oaks of Tuckaway... on the grounds that this is a major change to the Plan Unit Development and as a major change to a PUD would require a public hearing." On a roll call vote, the motion carried unanimously.3

The Project was again the subject of debate at a March 27, 1990, Planning Commission meeting. During this meeting, the city engineer brought up nine points that, because of the intense consideration of the density and rental issues, had not been adequately addressed. Principal among these points was the need to present revised plans that would bring the proposed *267buildings into conformity with the City's height requirements. The Commission asked the developers to submit a formal response to the city engineer's points.

Ten months later, on January 29,1991, Tuckaway submitted plans addressing the nine technical concerns raised by the city engineer. On February 12, 1991, the Commission voted to forward the petition to the Common Council with no recommendation — other than a recommendation to conduct a public hearing.

The Common Council held public hearings on April 3 and April 8, 1991. At the April 8 meeting, the Council voted unanimously to reject the project on grounds of aesthetic compatibility and economic feasibility.

Tuckaway appealed the adverse decision of the Common Council to the City's Board of Zoning Appeals. On June 27, 1991, after oral and written submissions by both Tuckaway and the City, the Board unanimously upheld the determinations of the Common Council.

From this procedural history arose two separate causes of action. First, in August of 1990, Tuckaway filed a lawsuit against the City alleging that, rather than reject the Project on grounds that would not stand up to judicial scrutiny, the City was trying to thwart the Project by evading any decision at all. Consequently, Tuckaway's complaint alleged that the City's delay in rendering a decision violated its rights to due process. Second, following the Board of Zoning Appeals' decision to uphold the ruling of the Common Council denying approval of the Project, Tuckaway sought cer-tiorari review of the decision. The trial court consolidated the two cases. The due process claim was tried to the court on November,13 and 14, 1991. The *268trial court ruled that Tuckaway had not met its burden on the due process claim. The trial court also concluded that the Board of Zoning Appeals had acted within its discretion in denying approval for the Project. Tuck-away now appeals.

II. DUE PROCESS CLAIM

Tuckaway first argues that the trial court erred in concluding that the City did not deprive Tuckaway of property and liberty without due process of law. This claim is based on what Tuckaway characterizes as the City's deliberate refusal to timely and meaningfully consider the petition for approval of the Project.

Initially, the City moved for summary judgment on the due process issue. Following argument by counsel, the trial court stated:

The one thing that really has made me think and there really isn't a lot of case law on this but it is certainly going to justify Mr. Bowen to stay here for awhile and that is this constitutional denial of due process and the manner in which the plan commission was delaying consideration of this project and the history that was related by Mr. Bowen in his brief about what took place on the different meetings of this plan commission over a long period of time.

Consequently, the trial court ordered that "[t]he defendant's motion for Summary Judgment on the First Claim (Denial of Due Process) is denied insofar as the claim seeks remedy for an alleged denial of due process from the defendant's delay in reaching a decision on plaintiff's petition for development."

*269The matter then proceeded to trial by the court as a tort of intentional denial of procedural due process.4 *270After hearing evidence for two days, the trial court, in a written "Decision and Order," denied Tuckaway's due process claim stating:

The gravamen of procedural due process is notice and an opportunity to be heard with protections afforded based on the demands of the situation involved. Since it must of necessity be an intentional tort, Tuckaway must so prove by evidence that is clear, satisfactory and convincing.

Herein, plaintiffs have not even met the ordinary civil burden let alone the so-called middle burden. Can anyone seriously argue that plaintiffs [through Gallina] were not afforded the opportunity to be heard. Numerous meetings with technical people and Plan Commission members were held with full discussion of the facts, merits and objectives of the project. In addition there were public hearings held whereat [sic] Gallina explained the project.

Plaintiffs [and Gallina] are obviously disappointed and disgruntled at how they were "horsed around" for a lengthy period of time prior to rejection but they did have every opportunity to be heard. Whatever possible tort that exists for denial of due process fails for almost total lack of proof.

Tuckaway claims it took 18 months from the time of the first pre-petition conference until eventual rejection in early April 1991 whereas the average PUD processing period usually took six months.

While factually correct ten of those eighteen months are attributable to Gallina's foot-dragging in presenting revised plans necessitated by his buildings exceeding the city's height ceilings. *271Whether Gallina's reluctance to proceed was justified or not, the fact is most of the processing delay is attributable to plaintiffs and not the city.

The United States Supreme Court has noted the following regarding the Due Process Clause: "As our decisions have emphasized time and again, the Due Process Clause grants the aggrieved party the opportunity to present his case and have its merits fairly judged." Logan v. Zimmerman Brush Co., 455 U.S. 422, 433 (1982). One specific implication of this rule is that " [unreasonable administrative delay can deprive a party of property without due process." Chicago & N. W. R.R. v. LIRC, 91 Wis. 2d 462, 480, 283 N.W.2d 603, 612 (Ct. App. 1979), aff'd, 98 Wis. 2d 592, 297 N.W.2d 819 (1980). Further, a governmental action that is arbitrary, irrational or tainted by improper motive violates an individual's right to due process. Bello v. Walker, 840 F.2d 1124, 1129 (3rd Cir.), cert. denied, 488 U.S. 868 (1988). In conjunction with these statements of law, we are guided by the rule that on review, findings of fact made by the trial court will not be set aside unless clearly erroneous. See sec. 805.17(2), Stats.

Our review of the record reveals that the trial court's findings of fact in regard to Tuckaway's due process claim were not clearly erroneous. First, there is ample proof that Gallina did indeed cause a substantial portion of the delay in the petition process. Gallina admitted that he had "dragged his heels" in attempting to obtain approval for the Project. He also stated that "the fact that it took until February 1991 to submit this [a response to the city engineer's nine points of contention] was solely and exclusively at my feet." Further, the trial court found that Tuckaway's threats of litigation also resulted in some delay: "These threats *272stiffened the City's resolve and also made it more responsible to see that proper legalities were observed." This finding is also amply supported. As noted by Alderman Waite in describing his motivation for resubmitting the issue to the Planning Commission, "Mr. Loeb [a partner in Tuckaway] threatened that you guys are going to get the [expletive] sued out of you."

Additionally, as noted by the trial court: "Numerous meetings with technical people and Plan Commission members were held with full discussion of the facts, merits and objectives of the project. In addition there were public hearings held whereat [sic] Gallina explained the project." The bottom line is that the administrative delay was not unreasonable.

Given these facts, we conclude that Tuckaway was afforded ample opportunity to be meaningfully heard concerning the petition for Project approval. The record supports the trial court's determination that the City did not orchestrate procedural irregularities in an effort to avoid meaningful consideration of the Project. On the contrary, the City simply proceeded cautiously in an effort to obtain a result that it believed was both correct and legally sound in light of the concerns raised by those involved in the process. Accordingly, we affirm the trial court decision that Tuckaway failed to meet its burden of proof concerning a claim for the intentional denial of due process and, therefore, the trial court committed no error in denying the claim.5

*273III. CERTIORARI PROCEEDING

Tuckaway's next claim concerns the Board of Zoning Appeals' affirmance of the Common Council's decision to reject approval for the Project. On certio-rari, the trial court upheld the decisions of both the Council and Board. Tuckaway takes issue with the manner in which the Council and Board proceeded. Tuckaway asserts: (1) the Board and the Council proceeded under an incorrect theory of law; (2) the record provides no reasonable basis for rejecting the Project on aesthetic or economic feasibility grounds; and (3) the Board's decision was not supported by factual findings or rationally expressed.

Our consideration of these assertions is guided by Ledger v. Waupaca Board of Appeals, 146 Wis. 2d 256, 261, 430 N.W.2d 370, 371-72 (Ct. App. 1988), where we stated:

Certiorari proceedings are limited to the record made before the administrative body and are quite narrow in scope. The reviewing court is limited to determining four issues: (1) whether the board acted within its jurisdiction and authority; (2) whether it proceeded on a correct theory of law; (3) whether its action was arbitrary, oppressive or unreasonable; and (4) whether the evidence was such that the board might reasonably make the determination it did.

A. Theory of Law

Tuckaway first argues that the Council and Board of Zoning Appeals proceeded under an incorrect theory of law because they applied criteria pertinent to a proposed new PUD instead of those pertinent to a *274proposed amendment to an existing PUD. Tuckaway argues: (1) the criteria to be applied to review of a proposed change to an approved PUD are found in sec. 21.47(7)(d) of the zoning code; (2) aesthetics and economic feasibility are not listed as review criteria in this subparagraph; and (3) therefore, when the Common Council utilized aesthetics and economic feasibility as bases for denial, it applied irrelevant criteria, and when the Board upheld that application, it erred. We are not persuaded.

Section 21.47(7)(d) provides, in relevant part:

Any subsequent change or addition to an approved plan shall first be submitted for recommendation to the Plan Commission. The Plan Commission shall make its recommendation to the City Council. If, in the City Council's opinion, the change or addition is substantial, keeping in mind subpar. 1., 2., 3., 4., the City Council shall call for another public hearing. Without limitation to the City Council's right to determine any other substantial change, a change in any of the following may be construed to be as substantial.

The Code goes on to delineate four changes which constitute a substantial change — none of which includes the concepts of aesthetics and economic feasibility. This, however, is not controlling. Section 21.47(7)(d) indicates that the Council is not limited to the four substantial change listings. Thus, the Council was free to consider aesthetics and economic feasibility in rendering its decision.6

*275 B. Aesthetics and Economic Feasibility

Tuckaway next argues that even if aesthetic and economic factors are proper standards to be applied in reviewing its petition for the Project, the record is barren of any grounds to support rejection of the petition on these bases. We disagree.

The minutes of the various hearings reflect concern among both citizens and city officials regarding the construction of a new project in their community. A careful review of these minutes suggests that the potential existence of rental usage caused great concern. The rental vacancy rate in other projects called to question the economic feasibility of the project. Further, the question of density focused attention on possible traffic, congestion and service problems. Finally, the design compatibility of the Project with other surrounding neighborhood buildings was discussed. Many of the citizens voiced their opposition to the design compatibility of the Project. In sum, the record contains ample support for the Project to have been rejected on aesthetic and economic factors.

C. Factual Findings of the Board

Tuckaway lastly claims that the Board of Zoning Appeals' decision was procedurally improper because the Board failed to make findings of fact or to articulate any reason for its decision. Tuckaway argues that, at a minimum, the matter should be remanded to the Board to allow it to make specific findings of fact with respect *276to its appeal. See Edmonds v. Board of Fire & Police Comm'rs, 66 Wis. 2d 337, 346-48, 224 N.W.2d 575, 580-81 (1975) (where factual basis for board's decision is unknown, case should be remanded to the board for specific findings of fact and conclusions of law).

A review of the record reveals the following. The Board of Zoning Appeals met on June 27,1991, to consider Tuckaway's appeal. Both parties were present and were represented by counsel. The chairman of the Board, with no objections from the parties, announced that the Board would hear statements from counsel representing both Tuckaway and the City. The Board had before it substantial written argument, a complete set of the Common Council's minutes concerning the April 3 and 8, 1990 meetings, and a tape of a meeting held April 5,1990, between the city attorney and counsel representing the competing interest groups. Following the arguments of counsel, Alderman Allan moved to deny the appeal, stating:

I believe the Common Council has every right to make its decision based on aesthetics and economics in all PUDs. These are prime reasons for their Council to even be considering a project. How it could act if it didn't decide on these very important issues if aesthetics and economic factors were what the Council based its decision on, and I think the Council was correct.

Thereafter, by roll call, all members of the Board voted to deny Tuckaway's appeal.

In State ex rel. Harris v. Annuity & Pension Bd., 87 Wis. 2d 646, 275 N.W.2d 668 (1979), our supreme court had the opportunity to examine what was minimally required to satisfy due process requirements. There, *277the petitioner, citing the rule of Edmonds, contended that the Board erred in failing to file a written decision setting forth the reasons for its findings. Id. at 660, 275 N.W.2d at 675. The petitioner argued, as does Tuck-away here, that remand should be made with directions to make specific findings. Id. The court declined to remand concluding, under the circumstances, that remand was "inappropriate." Id. In reaching its decision, the court stated the following: "There is no requirement that the administrative agency indulge in the elaborate opinion procedure of an appellate court. It is sufficient if the findings of fact and conclusions of law are specific enough to inform the parties and the courts on appeal of the basis of the decision." Id. at 661, 275 N.W.2d at 675. See also Synder v. Waukesha County Zoning Bd., 74 Wis. 2d 468, 476, 247 N.W.2d 98, 103 (1976), (" [Findings of the board may not be disturbed if any reasonable view of the evidence sustains them.").

In the present case, the findings of fact and the conclusion of law rendered by the Board of Zoning Appeals were specific enough to inform the parties, as well as this court on appeal, of the basis of the decision. As noted above, the Board had before it the minutes from the Common Council's meetings regarding the project and entertained statements from both parties concerning all facets of the Project. Although succinct, the findings of the Board are clear — the Council rejected the Project based on aesthetics and economic feasibility, both of which were proper criteria on which to render a decision. Based on these considerations, the Board denied Tuckaway's appeal.

*278We conclude that a remand for a detailed set of findings is not necessary to satisfy minimal due process requirements.

IV. SUMMARY JUDGMENT RULINGS

Tuckaway next posits that the trial court erred in granting adverse summary judgment rulings on its claims for inverse condemnation, breach of contract and tortious interference with a contract. We examine each contention seriatim.

. In reviewing a motion for summary judgment, appellate review is de novo, utilizing the same methodology as the trial court. Bong v. Cerny, 158 Wis. 2d 474, 478, 463 N.W.2d 359, 361 (Ct. App. 1990). Summaxy judgment "shall be rendered if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." Section 802.08(2), Stats.

A. Inverse Condemnation

Tuckaway claims that the City's refusal to approve the Project deprived it of all or substantially all of the property's beneficial use, thereby constituting a taking under Art. I, sec. 13, of the Wisconsin Constitution.7 We disagree.

In a recent analysis of an inverse condemnation claim, we stated:

*279In the absence of its physical occupancy or possession, private property can be taken for public use only by state, county or municipal action which imposes a legally enforceable restriction on the use of the property. If a legally enforceable restriction is imposed on that use, then a taking occurs only if the restriction deprives the owner of all, or practically all, of the use.

Reel Enters. v. City of La Crosse, 146 Wis. 2d 662, 674, 431 N.W.2d 743, 749 (Ct. App. 1988). See also Howell Plaza, Inc. v. State Highway Comm'n, 92 Wis. 2d 74, 84-85, 284 N.W.2d 887, 892 (1979) (taking occurs where governmental agency places legal restriction upon property that practically or substantially renders the land useless for all reasonable purposes).

As an undisputed historical fact, no legally enforceable restriction was imposed on the property in question. As noted above, the delay associated with the petition process was not caused by the City. Further, Tuckaway has not made a prima facie showing that it has been deprived of all, or practically all, of the use to which its land can be put. Granted, its initial proposal has been denied. However, Tuckaway still has the opportunity to present revised plans for a project that conforms with the aesthetics cf the surrounding neighborhood and is shown to be economically feasible. We conclude that there are no genuine issues of material fact as to Tuckaway's inverse condemnation claim and, therefore, affirm the trial court's order for summary judgment.8

*280 B. Breach of Contract

Tuckaway next claims that the City breached an implied agreement derived from the 1987 Amended Declaration of Restrictions — that Tuckaway would be permitted to build any reasonable project on the property that conformed to the modified density requirements. The trial court disagreed, basing its decision on the fact that the Amended Declaration plainly and unambiguously stated: "It is mutually agreed that this Amendment is complementary to the Planned Development Ordinance of the City and that the development hereinabove described is subject to the said ordinance." On appeal, Tuckaway argues that this statement is ambiguous and, therefore, summary judgment should not have been granted.

Contractual language is ambiguous only when it is "reasonably or fairly susceptible of more than one construction." Borchardt v. Wilk, 156 Wis. 2d 420, 427, 456 N.W.2d 653, 656 (Ct. App. 1990). Construction of a contract, including the determination of whether its terms are ambiguous, is a legal matter that we decide de novo. Id. Unambiguous contractual language must be enforced as it is written. Dykstra v. Arthur G. McKee & Co., 92 Wis. 2d 17, 38, 284 N.W.2d 692, 702-03 (Ct. App. 1979), aff'd, 100 Wis. 2d 120, 301 N.W.2d 201 (1981). Further, we may not use the mechanism of construction to revise an unambiguous contract in order to relieve a party to a contract "from any disadvantageous *281terms" to which he or she has agreed. Id. at 38, 284 N.W.2d at 703.

In the present case, we conclude that the language at issue in the 1987 Amended Declaration of Restrictions is unambiguous. The Amended Declaration clearly states that the development described is not only complementary to the Planned Development Ordinance, but is also subject to its terms. We conclude that this provision is reasonably susceptible of only one construction. Because the Declaration set forth its terms plainly and unambiguously, the trial court properly concluded that there were no issues of material fact surrounding a breach of any implied agreement between the parties and, accordingly, appropriately granted summary judgment in favor of the City.9

*282 C. Tortious Interference With a Contract

Finally, Tuckaway claims the trial court erred in ruling that the immunity provisions of sec. 893.80(4), Stats., barred its tortious interference with a contract claim. Tuckaway argues that sec. 893.80(4) is not intended to afford governmental bodies immunity from their own intentional torts; rather, the statute provides immunity to governmental bodies for the intentional torts of its agents.

Section 893.80(4), Stats., reads:

893.80 Claims against governmental bodies or officers, agents or employes; notice of injury; limitation of damages and suits.

(4) No suit may be brought against any volunteer fire company organized under ch. 213, political corporation, governmental subdivision or any agency thereof for the intentional torts of its officers, officials, agents or employes nor may any suit be brought against such corporation, subdivision or agency or volunteer fire company or against its officers, officials, agents or employes for acts done in the exercise of legislative, quasi-legislative, judicial or quasi-judicial functions.

. A plain reading of the statute indicates: (1) it provides immunity for governmental bodies in situations where their agents or employees commit intentional torts; and (2) it provides immunity for the agents or employees of governmental bodies where those individuals are acting within the exercise of a legislative, quasi-legislative, judicial or quasi-judicial function.

*283Tuckaway claims the City itself, by its acts and omissions, interfered tortiously with the contractual relationship it had established with Tuckaway. Such interference, however, could not occur except through the actions of an official or agent of the City. Further, because the acts and omissions complained of occurred within the exercise of quasi-legislative or quasi-judicial actions, the agents and employees of the City who undertook those actions, as well as the City itself, are immune from suit as a matter of law. Therefore, summary judgment was properly granted in favor of the City.10

By the Court. — Judgment affirmed.

{concurring). The significance of footnote 4 of our decision merits added emphasis.

Essentially, Tuckaway claims that the City employed improperly motivated pretexts to postpone and deny its application. The City responds that it provided the required hearings, followed the correct procedures, rendered a legally tenable denial and, therefore, that Tuckaway has no cause of action for intentional denial of due process.

If, however, the City never intended to provide a decision on the merits and, as a result, its hearings and procedures were a sham, then neither formal compli-*284anee with procedures nor theoretical tenability of a denial would make any difference. The trial court was correct in allowing Tuckaway to pursue that theory.

Therefore, if the trial court, in its summary judgments, had foreclosed Tuckaway's opportunity to attempt to prove that the City's procedures were pretextual and its decision-making process a sham, my conclusion in this case would have changed. Because, however, despite some troubling ambiguity in the reach of the summary judgments and the range of the resulting court trial, it appears that the trial court permitted Tuckaway to pursue its theory, and because, in footnote 4, we have recognized the viability of such a claim, I concur.
