Eminent Domain in Plain English: What "Public Use" and "Just Compensation" Mean
by C. V. Wooster · October 5, 2026 · 4 min read
Eminent domain is the power of government to take private property for public use. It is old, it is in the Constitution, and most people never think about it until a survey stake appears at the edge of their land. Mrs. Orcutt's Driveway is, in part, a story about that moment. This post explains the basic ideas in plain language so readers can follow the stakes in the book.
A note before we start: this is history and general background. It is not legal advice. If you are facing a taking today, talk to a lawyer who practices eminent domain law in your state.
The sentence in the Fifth Amendment
The power itself is not granted by the Constitution. Courts have long treated it as something every sovereign government has. What the Constitution adds is a limit. The last clause of the Fifth Amendment says: "nor shall private property be taken for public use, without just compensation."
That short clause contains three ideas that shape almost every eminent domain dispute.
- Taken. Something must actually be taken, or so badly burdened that the law treats it as taken.
- Public use. The taking must serve a public purpose.
- Just compensation. The owner must be paid fairly for what is lost.
The clause was first understood as a limit on the federal government. After the Fourteenth Amendment, the Supreme Court applied the same requirement to the states, so state highway departments are bound by it too.
What counts as public use
For a highway, public use is rarely in doubt. Roads, bridges, schools, and water lines are the classic examples. The harder cases involve takings where the land ends up with a private owner, such as redevelopment projects.
The best-known modern case is Kelo v. City of New London, decided by the Supreme Court in 2005. The Court held, five to four, that a city could take homes as part of an economic development plan, because the plan served a public purpose even though private developers would build on the land. The decision was unpopular, and many states responded by passing laws that narrowed when their own governments could take property for economic development.
None of that was at issue in the Mojave in the 1960s. Nobody seriously argued that an interstate highway was not a public use. The fight, where there was one, was about the other two words: what exactly was being taken, and what it was worth.
Just compensation and fair market value
Courts usually measure just compensation by fair market value: what a willing buyer would pay a willing seller for the property, with neither forced to act. That sounds simple. It often is not.
Fair market value does not usually pay for sentimental attachment, for the years of work an owner put into a house, or for the inconvenience of moving. It pays for the property as the market sees it. A widow's hand-built adobe house on remote desert land might have deep meaning to her and modest value on paper. That gap is one reason eminent domain disputes can feel unfair even when the law is followed to the letter.
When only part of a property is taken, the question gets harder. The owner may be entitled to the value of the strip that was taken plus "severance damages," the loss in value to the land that remains. If a new road cuts a parcel in two, or leaves the rest without good access, that loss can be larger than the value of the strip itself.
California's extra word: "damaged"
California's constitution goes a step further than the federal one. Article I, Section 19 says that private property may be "taken or damaged" for a public use only when just compensation has first been paid. The word "damaged" matters. It reflects the idea that a public project can hurt an owner without taking any land at all.
California courts have long recognized that an owner whose land abuts a public road has a right of reasonable access to that road, and that substantially impairing that access can be compensable. Not every inconvenience qualifies. A longer drive to the same road usually does not. Losing all practical access is a different matter.
That is the legal background to a story like Bonnie Orcutt's. Her concern, in her own words in a 1965 letter to Lady Bird Johnson, was simple: "I only want what I have at present: a road on and one off of the present Highway (66)."
Inverse condemnation
Sometimes the government does not formally take property but its project causes the same kind of loss. In that case, the owner may bring what lawyers call an inverse condemnation claim. The name means the owner, not the government, starts the case, asking a court to recognize that a taking or damaging has happened and to order compensation.
Inverse condemnation claims are technical, slow, and expensive. For most individual owners in the 1960s, especially in remote places, a lawsuit was not a realistic first step. Letters were.
Why letters mattered
The legal tools above work best when an owner has a lawyer, money, and time. Many of the people in the path of the interstates had none of those. What they had was the ability to explain their situation to someone with the power to change a plan before the concrete was poured.
A well-placed letter could do things a lawsuit could not. It could ask for a frontage road, an access point, or a slight shift in a line. It could do so before decisions became final. And it cost a stamp. Mrs. Orcutt's Driveway follows one woman who understood that, and kept writing.
Where to read more
If you want to go deeper, start with the text of the Fifth Amendment and California's Article I, Section 19, then read a summary of Kelo to see how the public use debate evolved. For the human side, read the book.
