S.C. Code § 48-9-600
The department shall publish the result of such referendum and shall thereafter consider and determine whether the operation of the district within the defined boundaries is administratively practicable and feasible. If the department shall determine that the operation of such district is not administratively practicable and feasible it shall record such determination and deny the petition. If the department shall determine 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 provided in Sections 48-9-610 to 48-9-630. In making such determination the department shall give due regard and weight to the attitudes of the owners and occupiers of lands lying within the defined boundaries, the number of landowners eligible to vote in such referendum who shall have voted, the proportion of the votes cast in such referendum in favor of the creation of the district to the total number of votes cast, the approximate wealth and income of the landowners and occupiers of the proposed district, the probable expense of carrying on erosion-control operations within such district and such other economic and social factors as may be relevant to such determination, having due regard to the legislative determinations set forth in Section 48-9-20. The department shall not have authority to determine that the operation of the proposed district within the defined boundaries is administratively practicable and feasible unless at least a majority of the votes cast in the referendum upon the proposition of creation of the district shall have been cast in favor of the creation of such district.
