The appointment of commissioners or condemnation jurors and all proceedings thereafter shall be governed by the procedure prescribed for the condemning authority. Notwithstanding the provisions of § 25.1-100, the date of valuation in actions pursuant to this section shall be the date determined by the court to be the date the property was taken or damaged.
