Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 551.050

At the time advertised for the hearing of interested parties, the court may postpone the hearing as may be necessary in order to allow the viewers more time in which to report, or for other good cause. If, upon the final hearing, the county court, from the report of the viewers and the testimony of interested persons, believes that the benefits to be derived from forming a diking district are not sufficiently great to justify the expenditure which will be incurred, the petition and report shall be dismissed at the cost of the petitioners. If the court believes that the proposed improvement will be for the general public good, and that the increase in the taxable value of the land will be greater than the cost, or that destruction of or damage to property equal to the cost will be prevented, the petition shall be granted and the district formed, a number given by which it shall be designated in future proceedings, the report of the viewers adopted and incorporated in the court records, and the cost of the preliminary work assessed upon the district.
