The Courts:
Tiburon Taxpayers Celebrate New Year's Eve Ruling Invalidating Assessment on Property Owners

The First District Court of Appeal ruled December 31 that the town of Tiburon violated the state constitution by enacting an assessment that outweighed the benefits received by property owners who were forced to pay. The assessment, enacted to fund a major project to move utility lines underground, "violate the proportionality requirement of article XIII D," the court found.

Property owners who appealed the assessment "are entitled to a writ of mandate invalidating the assessments and vacating the Town's resolution creating the Supplemental District," the court ruled in Town of Tiburon v. Jimmie D. Bonander (A11918).

The case involved a "supplemental assessment district" approved by Tiburon property owners after projected costs of an undergrounding effort increased so much that the original assessment district could not cover the expenses. Once all expenses were accounted for, the project was determined to be $3.18 million over the original budget of $4.72 million. The money was to be paid by parcel owners based on the benefit received from the project. (The legality of the original assessment district also has been challenged by Mr. Bonander, but that case has not yet been decided.)

To determine the amount to be paid by parcel owners, the town used three "zones of benefit" in which construction costs were calculated separately. As a result of the cost-based apportionment system, owners of single-family residences with similar benefits for aesthetics, safety and service reliability would pay drastically different amounts based on their location. A parcel on West Hawthorne Drive was assessed $7,740, one in the Del Mar Valley Area was assessed $14,812, and a similar parcel on Hacienda Drive was assessed $20,331.

The court ruled that "the assessment scheme suffers from two infirmities that result in assessments that are disproportionate to special benefits." First, the apportionment method "is largely based on cost considerations rather than proportional special benefits." Secondly, properties within the supplemental district were required to pay for special benefits conferred upon parcels that were excluded from the district.

"If a property receiving a special benefit is excluded from the assessment district, then the assessments on properties included in the district will necessarily exceed the proportional special benefit conferred on those properties," the court ruled. In this case, two cul-de-sacs were exempted from the district, but the court said they received the same special benefits as parcel on similar streets within the district. Also, some of the parcels included in the district already had underground utility lines, but were assessed for the benefit of other nearby lines being moved underground.

The flaws "are simply too great to disregard as mere 'imperfections,'" the court stated.

Because the court found that the assessment violated the state constitution, the justices concluded that "we need not reach the other arguments appellants raise." Those arguments included claims that Tiburon officials unfairly affect the vote by misleading property owners into believing that assessments would be deductible from income taxes, and that the town agreed to pay for a school district's proposed assessment in exchange for the district abstaining from voting its 10 parcels against the supplemental district.

The ruling dealt only with the supplemental district. The First District noted that its decision "may have a bearing" on the lawsuit over the original assessment district "to the extent that litigation remains pending and raises the proportionality issue that is dispositive in this appeal."

Presiding Justice William McGuiness wrote the decision. Justices Peter Siggins and Martin Jenkins concurred.
