S.D. Codified Laws § 46A-10A-68
If a board establishes a project pursuant to § 46A-10A-65, it shall calculate the damage sustained by each tract of land or by other property due to construction or maintenance of the project. The board shall give notice of its determination of damages to the respective landowners and shall schedule a hearing thereon. Damages to crops growing during construction may be calculated at a later time and shall be considered part of the cost of construction. At the hearing, the board will receive evidence on the question of damages and just compensation. Any affected person or competent witness on his behalf may testify in the matter of damages or compensation for land. A determination of damages by the board after the hearing is final unless appealed as provided in this chapter. Any appeal from a board's determination of damages shall be heard in circuit court as a condemnation action. Failure to appear to contest or to appeal an award of damages shall be deemed acceptance of damages or compensation for land taken.
