Imagine an authorized government project acquiring private land for a public road. Eminent domain is the power behind that acquisition for public use, with just compensation. Follow the sequence from private property to the public-use taking and compensation. Condemnation is the legal process used to carry out that power. Compare this with ordinary land-use regulation. Zoning usually regulates use rather than acquiring title. Some regulations can raise a takings issue, but not every reduction in property value automatically requires compensation. Quick check: which power underlies acquiring private land for a public road? Eminent domain. Remember the power, the condemnation process, and the just-compensation requirement.
