It's a silly way to try and prevent oil or gas exploration and extraction. And it's stupid because I'll bet most of the county sits on split estate lands (that is, the surface estate belongs to one owner and the mineral rights belong to another.) If someone who owns the mineral rights attempts to exercise those rights and the city stops them, it would be called a "regulatory taking" and the city - which is to say the taxpayers - will be liable to pay the fair market value of the mineral rights taken which could run into the millions pretty easily.
BTW wasn't Lafayette originally built as a coal mining town? Or am I thinking of Louisville?![]()
