The case resulted in a settlement. Here is how Prof. Dukeminier describes it: "The state purchased Lucas's land for $850,000 and paid him another $750,000 in interest, attorney's fees, and costs. Strapped for the money (a total of $1,575,000), the state resold the lots to a construction company!"
Lol! When it was the landowner's investment at risk, the state said it would be the end of the beach if Lucas could build on his land. But once the state bought the land, it sold the land to a construction company to recoup its investment. The Takings Clause requires the government to decide--with its own funds-- whether a particular taking is worth the cost of compensation.
