Va. Code § 10.1-514
After the Board has made and recorded a determination that there is need for the organization of the proposed district in a particular territory, and has defined the boundaries, it shall consider whether the operation of a district within such boundaries is administratively practicable and feasible. In making its determination, the Board shall consider the attitudes of the occupiers of lands lying within the defined boundaries, the probable expense of the operation of such district, the effect upon the programs of any existing districts, and other relevant economic and social factors. If the Board determines that the operation of a district is administratively practicable and feasible, it shall record its determination and proceed with the organization of the district. If the Board determines that the operation of a district is not administratively practicable and feasible, it shall record its determination and deny the petition. If the petition is denied, the Board shall notify the petitioner in the manner provided in this chapter.
