IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION FIVE

LEANNE THOMPSON, Plaintiff and Appellant, A168185, A168978 v. CITY OF WALNUT CREEK, (Contra Costa County Defendant and Respondent. Super. Ct. No. MSN16-0201)

Leanne Thompson commenced this action against the city of Walnut Creek, alleging causes of action that included writ of mandate, takings, and due process violations related to a building permit for her house remodel.

The trial court denied all but one of Thompson’s writ claims after hearing. It found in favor of the city on the takings cause of action after a bench trial. The court then dismissed the due process cause of action because the issues had been litigated and decided against Thompson. It also declined to grant the writ relief requested by Thompson as moot and improper. We affirm.

BACKGROUND

A.

Thompson submitted a building permit application for a $140,000 house remodel. The city issued the permit. According to Thompson, her project encountered “several unanticipated

1 problems” that required her contractor to perform more work. According to the city, the project was misrepresented on the permit application and, in fact, had a $297,212 construction value. Given the $341,000 assessed value of the house, the project constituted a substantial improvement subject to additional construction requirements. (Walnut Creek Mun. Code, § 9-12.1.302, subd. (ao) [defining “[s]ubstantial [i]mprovement” to include improvements with a cumulative cost that equals or exceeds 50 percent of the market value of the structure (italics omitted.)].)1

One such requirement was that frontage improvements be installed “in accordance with the street setback line.” (§ 9-9.205, subd. (a)(2)(ii).) Another requirement was that, for houses like Thompson’s within a flood hazard area, the lowest floor elevation be two feet above base flood elevation. (§ 9-12.1.101 et seq. (floodplain ordinance); see also §§ 9-12.1.302, 9-12.1.405.)

Thompson appealed to the city council, requesting a variance from application of those requirements. The council denied the appeal.

B.

Thompson filed this action against the city as well as two individual defendants, both of whom were subsequently dismissed. The operative pleading asserted causes of action for writ of mandate, takings, and violations of due process.

The trial court granted the city’s motion to bifurcate and heard the petition for writ of mandate first. The court largely denied the petition but found the city could not require Thompson to comply with the setback requirement.

1 Undesignated section references are to the Walnut Creek

Municipal Code. 2 The matter proceeded on Thompson’s remaining claims. At a pretrial conference, the court ordered that Thompson’s takings cause of action be tried before her due process cause of action and damages claims. At the conclusion of the bench trial, Thompson argued she had proven her takings claim through two alternative legal theories: (1) that the city’s actions constituted a per se taking, or (2) that Thompson had a “vested right” in her building permit. The court determined Thompson had failed to establish a taking under either theory and the city was entitled to judgment in its favor on the takings cause of action.

The parties submitted briefing and argument on whether Thompson was entitled to a jury trial on any remaining claims, in light of the trial court’s previous rulings. The court dismissed the due process cause of action because those rulings had “adjudicated all issues.”

The parties then submitted briefing and argument on whether Thompson was entitled to any remedy arising out of the trial court’s order on her petition for writ of mandate. The court found the relief she requested was moot because the city’s setback requirement no longer applied to single-family homes like hers, and it was improper given the court’s factual findings from the bench trial.

DISCUSSION

Thompson challenges the trial court’s ruling that she failed to establish her takings cause of action.

“Both the United States Constitution and the California Constitution provide that when a public entity takes private property for a public use just compensation must be paid to the property owner.” (Property Reserve, Inc. v. Superior Court (2016) 1 Cal.5th 151, 185; U.S. Const., 5th Amend. [private property shall not “be taken for public use, without just compensation”]; 3 Cal. Const., art. I, § 19, subd. (a) [private property “may be taken or damaged for a public use and only when just compensation, ascertained by a jury unless waived, has first been paid to, or into court for, the owner”].)

The determination of whether government action constitutes a taking involves three steps: “(1) the determination of the historical facts--what happened; (2) selection of the applicable legal principles; and (3) application of those legal principles to the facts.” (Ali v. City of Los Angeles (1999) 77 Cal.App.4th 246, 250 (Ali).) The first step involves factual questions exclusively for the trial court to determine and subject to substantial evidence review. (Ibid.) The second and third steps involve questions of law for our de novo review. (Ibid.)

For an appeal challenging the sufficiency of evidence by a plaintiff who succeeded at trial, we “must view the evidence in the light most favorable to the judgment and the findings, express or implied, of the trial court.” (Ali, supra, 77 Cal.App.4th at p. 250.) But for an appeal like this one, challenging the trier of fact’s conclusion that Thompson failed to carry her burden of proof at trial, “ ‘the question for a reviewing court becomes whether the evidence compels a finding in favor of the appellant as a matter of law.’ ” (Sonic Manufacturing Technologies, Inc. v. AAE Systems, Inc. (2011) 196 Cal.App.4th 456, 466 (Sonic), quoting In re I.W. (2009) 180 Cal.App.4th 1517, 1527-1528.)

With this framework in mind, we turn to the merits of Thompson’s arguments that she proved (1) per se takings by the city, and (2) application of the vested rights doctrine.

4 1.

“ ‘In view of the nearly infinite variety of ways in which government actions or regulations can affect property interests,’ the United States Supreme Court has identified only certain narrowly-defined categories of ‘government interference with property’ that are considered per se (or ‘categorical’) takings.” (Surfrider Foundation v. Martins Beach 1, LLC (2017) 14 Cal.App.5th 238, 264 (Surfrider), quoting Arkansas Game & Fish Commission v. United States (2012) 568 U.S. 23, 31.) “These include ‘regulations that completely deprive an owner of “all economically beneficial us[e]” of her property,’ as well as governmental action that ‘requires an owner to suffer a permanent physical invasion of her property—however minor.’ ” (Surfrider, at p. 264, quoting Lingle v. Chevron U.S.A. Inc. (2005) 544 U.S. 528, 538.)

Here, the trial court determined Thompson made no showing that the city’s conduct “deprived her of all economically beneficial or productive use of the land.” On the contrary, the city had shown that other property owners on her street had redeveloped their properties in accordance with the floodplain ordinance.
