Whether Lots E and F should be treated as one parcel or as separate parcels when measuring the alleged regulatory taking.
Holding
Yes. For this takings inquiry, Lots E and F properly constituted a single parcel.
Reasoning
The Court explained that a regulatory-takings claim requires comparing the value lost because of a regulation with the value that remains. Identifying the relevant unit of property—the denominator of that comparison—is therefore important, but no single bright-line rule resolves the question. The Takings Clause inquiry must avoid artificially defining the property as only the segment directly burdened by the challenged regulation, as the Court had refused to do with air rights in Penn Central and a temporary period of restricted use in Tahoe-Sierra.
The proper inquiry is objective: courts should ask whether reasonable expectations about ownership would lead a landowner to anticipate that the holdings would be treated as one parcel or as separate tracts. Courts should give substantial weight to state and local law, including how the land is bounded and regulated, while recognizing that state law cannot alone define away a constitutional takings claim.
Courts also must consider the land’s physical characteristics. Relevant considerations include whether the tracts are contiguous, their terrain and topography, and their surrounding human and ecological setting. Land located in an area long subject to environmental regulation may carry objectively reasonable expectations of more extensive land-use restrictions.
Finally, courts should consider the regulated land’s contribution to the value of the owner’s other holdings. A burden on one tract may be mitigated when that tract increases the value of an adjoining tract by providing privacy, recreation, space for improvements, or protected views. Conversely, separate and nonadjacent holdings without such a relationship may be less likely to form one parcel.
Applying those considerations, the Court held that the Murr lots formed one parcel. State and local law validly merged the adjacent substandard lots after the siblings brought them into common ownership. The lots were contiguous, similarly shaped by steep terrain, and located beside a river that had long been subject to federal, state, and local protection. Lot E also added meaningful value to Lot F by increasing privacy and recreational space and by allowing a more advantageous location for improvements. The combined lots’ appraised value of $698,300 exceeded the sum of their asserted separate regulated values, confirming their complementary relationship.
