(2) The reduction in the fair market value of the real property shall be determined by comparing the fair market value of the real property as if the regulatory program is not in effect and the fair market value of the real property determined as if the regulatory program is in effect.

(3) To assert that a taking has occurred, the regulatory program must have been implemented at the time the owner acquired title or after April 2, 2015, whichever is later.
