(1)In case the report of the state engineer is adverse to the formation of such district because it is not considered feasible, he shall state his reasons for such conclusion in concise language and shall call attention thereto expressly in his letter transmitting such report to the board of county commissioners. The board of county commissioners shall thereupon fix and determine, upon such investigations and hearings as they see fit, the following matters and things:
(a)Whether the statutory requirements preliminary to organization have been substantially complied with, which determination shall be reviewable only by an action in the nature of certiorari issuing out of the district court having jurisdiction and upon application therefor made within fifteen days of the date of determination by the board of county commissioners;
(b)Fix the territorial extent and boundaries of such district and, in so doing, consider the petition upon which hearing is had, together with such petitions for inclusion within or exclusion from said district as are presented.
(2)No lands shall be excluded from said district which are susceptible of irrigation from the source of water supply intended for the irrigation of the district and not more easily irrigable from another source, nor shall any lands be included within said district which are not susceptible of irrigation from the source of supply intended for the district, or which are already irrigated, or which can be more easily irrigated from another source.
(3)Objection to such exclusions or inclusions, or the order fixing the territorial extent and boundaries of the district, shall be made in writing by the interested landowners, on or before such date of hearing or adjournment thereof, and an appeal from such adverse determination prosecuted to the district court of the county wherein such hearing is had, as in the case of appeals from disallowance of claims, insofar as applicable, within fifteen days from such determination. No such appeal having been prosecuted, the determination of the board of county commissioners shall be deemed conclusive on such points.
