I don't get it. BCH says they can't or won't upgrade the dam. At the end of Hopper's article he states that BCH is "not aware of any dams in the world” capable of safely damming this river. At the beginning of the same article, the cost of replacement is cited as a reason it is not being replaced.
BCH hasn't been shy about saying how much they need the power from this dam. 170 MW isn't huge, but it also isn't negligible.
So it's a super valuable asset BCH won't replace but can't live without. Alright then...
If the big one hits, the last thing anybody's going to be worried about is 11 houses in Jordan River (sorry Jordan Riverites). Why is BCH making such a fuss about this? Inform the landowners of the issue, offer to purchase their property at fair market value and be done with it. If they understand the risks and still don't want to sell, then that's their prerogative.
