(a) The municipal board on sign control shall determine the amount of the compensation to which the owner of a sign that is required to be relocated, reconstructed, or removed is entitled. The determination shall be made after the owner of the sign is given the opportunity for a hearing before the board about the issues involved in the matter.
(b) In any court proceeding in which the reasonableness of compensation is at issue and the compensation is to be provided over a period longer than one year, the court shall consider whether the duration of the period is reasonable under the circumstances.
