Va. Code § 21-323
If it shall be necessary to acquire a right-of-way and outlet over and through any lands or to remove any dam or other obstacle, whether the same is or is not operated under a decree of court, and the same cannot be acquired by purchase at a price deemed reasonable by the court upon report to the court by the board of viewers thereupon, then in such event the power of eminent domain is conferred, and the same may be condemned. Such owner of the land, dam, or other obstacles proposed to be condemned, may all be made parties defendant in one condemnation suit or proceeding, whether such owner or owners are all interested in one tract or parcel of land, dam or other obstacle, or different owners are interested in different tracts or parcels of land or different dams or other obstacles, and the procedure in such condemnation suit or proceeding shall be under the restrictions provided by the general statutes of this Commonwealth relative to the condemnation of land so far as the same may be applicable and are not in conflict with the provisions of this chapter.
