If a city needs a property for airport runway expansion, and the owner refuses to negotiate, what can the city enforce?

The situation described involves a city requiring a property for a public purpose, specifically for airport runway expansion, which falls under the principle of eminent domain. Eminent domain allows government entities to take private property for public use while providing just compensation to the property owner.

In this scenario, since the owner is not willing to negotiate, the city has the legal authority to invoke eminent domain. This legal principle is essential for facilitating the development of infrastructure that benefits the public, such as roads, schools, or airport facilities. The necessity for public benefit and the provision of compensation are critical components of the eminent domain process, ensuring that property rights are balanced with community needs.

The other options listed do not apply to this context. Escheat refers to the state acquiring property when an individual dies without a will or heirs; accretion involves the gradual increase of land due to natural forces; and confiscation typically pertains to the seizure of property due to illegal activities or violations of law, rather than for public use. Thus, eminent domain is the appropriate and lawful avenue the city can pursue in this instance.
