Let's just say that the local illegal hazardous waste dumpers would get an anonymous phone call telling them where they could dump their nasty stuff without interference.
Court precedent and the Bill of Rights does not allow this pond-scum's property to be taken without equitable and just compensation. You may argue what that compensation should be, but make no mistake, the government cannot take it without compensation.
Personally, I think cost + 10% + fees is more than equitable.
