(1) In all actions for the condemnation of lands under the provisions of KRS 416.550 to 416.670, except temporary easements, there shall be awarded to the landowners as compensation such a sum as will fairly represent the difference between the fair market value of the entire tract, all or a portion of which is sought to be condemned, immediately before the taking and the fair market value of the remainder thereof immediately after the taking, including in the remainder all rights which the landowner may retain in the lands sought to be condemned where less than the fee simple interest therein is taken, together with the fair rental value of any temporary easements sought to be condemned.
(2) Any change in the fair market value prior to the date of condemnation which the condemnor or condemnee establishes was substantially due to the general knowledge of the imminence of condemnation or the construction of the project shall be disregarded in determining fair market value. The taking date for valuation purposes shall be either the date the condemnor takes the land, or the date of the trial of the issue of just compensation, whichever occurs first.
