N.C. Gen. Stat. § 156-63
The clerk of the superior court shall consider this report. If the viewers report that the drainage is not practicable or that it will not benefit the public health or any public highway or be conducive to the general welfare of the community, and the court shall approve such findings, the petition shall be dismissed at the cost of the petitioners, and such petition shall likewise be dismissed at the cost of the petitioners if it is sought to set up a reclamation district and the viewers report that the cost of reclaiming the land would be so great as not to justify the expense of draining it. Such petition or proceeding may again be instituted by the same or additional landowners at any time after six months, upon proper allegations that conditions have changed or that material facts were omitted or overlooked. If the viewers report that the drainage is practicable and that it will benefit the public health or any public highway or be conducive to the general welfare of the community, and the court shall so find, then the court shall fix a day when the report will be further heard and considered.
