Section 553.350 - Assessment of benefits and damages by appraisers; benefits less than costs; recommendation to amend engineering plan; final report and certificate(1) The appraisers shall assess the amount of benefits and the amount of damages, if any, that will accrue to each tract of land which they are directed by the board of directors to appraise, and shall determine the value of any lands to be acquired and used for rights of way and other purposes by the subdistrict. The appraisers shall determine the benefits to the lands themselves and to any buildings and other structures erected on such lands. The appraisers shall take into consideration the agricultural or other uses of such lands, the increase in value thereof upon the completion of the proposed works, and the increased income which will be derived from the lands upon the construction of the works. In making their appraisal, the appraisers shall give due consideration and credit to any works that have already been constructed and which benefit any tract of land they are appraising. The appraisers shall have no power to change the engineering plan.(2) Whenever it appears to the appraisers that the benefits to all the lands within the subdistrict will be less in value than the cost of the proposed works, the appraisers shall file a preliminary report of their work with the board of directors and recommend to the board that the engineering plan be amended so that the proposed works can be constructed at a cost less than the benefits to be derived therefrom. If the board obtains an amended engineering plan, the appraisers shall proceed with their work.(3) Upon completing their work, the appraisers shall file a final report with the court and certify that the appraisal has been completed and that there is nothing further for them to do in regard to the matter.
