The Department shall publish the result of such referendum. If a majority of the owners of land lying within the district voted in favor of the creation of the district, and if the Department determines that the attitude of such owners, the approximate wealth and income of such landowners, the probable expense of carrying on erosion control operations within such district, and other economic and social factors as may be relevant are such that the operation of such district is administratively practicable and feasible, it shall record such determination and shall proceed with the organization of the district in the manner hereinafter provided. If less than a majority of the owners of land in such district vote in favor of the creation of such district, or if the Department determines that the attitude of such owners, the approximate wealth and income of such landowners, the probable expense of carrying on erosion control operations within such district, and other economic and social factors as may be relevant are such that the operation of the proposed district is not otherwise practicable and feasible, it shall record such determination and deny the petition.
