Justia Opinion Summary and Annotations

The St. Croix River, part of the boundary between Wisconsin and Minnesota, is protected under federal, state, and local law. State and local regulations prevent the use or sale of adjacent riverside lots under common ownership as separate building sites unless they have at least one acre of land suitable for development. Petitioners’ parents purchased adjacent Troy, Wisconsin lots separately in the 1960s, and transferred one lot to petitioners in 1994 and the other to petitioners in 1995. Each lot is over one acre, but because of the topography, each has less than one acre suitable for development; common ownership barred their separate sale or development. Petitioners unsuccessfully sought variances, then filed suit, alleging a regulatory taking. The state courts and U.S. Supreme Court rejected the claims, regarding the property as a single unit in assessing the effect of the challenged governmental action. The Court noted the flexibility inherent in regulatory takings jurisprudence. Courts must consider several factors. Wisconsin’s merger provision is a legitimate exercise of state power and the valid merger of the lots under state law informs the reasonable expectation that the lots will be treated as a single property. The lots are contiguous. Their terrain and shape make it reasonable to expect their range of potential uses might be limited. Petitioners could have anticipated regulation of the property, given its location along the river, which was regulated by federal, state, and local law long before they acquired the land. The restriction is mitigated by the benefits of using the property as an integrated whole, allowing increased privacy and recreational space, plus an optimal location for any improvements. This relationship is evident in the lots’ combined valuation.

Primary Holding

A valid merger under state law of contiguous lots with limited individual uses means that the lots should be regarded as a single unit in determining whether a government action regarding the property was a regulatory taking.
