Final answer:
Under the Fifth Amendment, the homeowner would be entitled to compensation based on the current market value of the entire property.
Step-by-step explanation:
Under the Fifth Amendment to the United States Constitution, the government has the power of eminent domain to take private property for public use, with the requirement that the property owner be given just compensation.
In the case of a homeowner whose front ten feet of the lot were taken for a sidewalk, the homeowner would be entitled to compensation. This compensation would be based on the current market value of the entire property, not the assessed tax value.
