The recordation of an approved plat shall operate to transfer, in fee simple, to the respective localities in which the land lies the portion of the premises platted as is on the plat set apart for streets, alleys or other public use and to transfer to the locality any easement indicated on the plat to create a public right of passage over the land. The recordation of such plat shall operate to transfer to the locality, or to such association or public authority as the locality may provide, such easements shown on the plat for the conveyance of stormwater, domestic water and sewage, including the installation and maintenance of any facilities utilized for such purposes, as the locality may require. Nothing contained in this article shall affect any right of a subdivider of land heretofore validly reserved. The clerk shall index in the name of all the owners of property affected by the recordation in the grantor’s index any plat recorded under this section. Nothing in this section shall obligate the locality, association or authority to install or maintain such facilities unless otherwise agreed to by the locality, association or authority. When the authorized officials of a locality within which land is located, approve in accordance with the subdivision ordinances of the locality a plat or replat of land therein, then upon the recording of the plat or replat in the circuit court clerk’s office, all rights-of-way, easements or other interest of the locality in the land included on the plat or replat, except as shown thereon, shall be terminated and extinguished, except that an interest acquired by the locality by condemnation, by purchase for valuable consideration and evidenced by a separate instrument of record, or streets, alleys or easements for public passage subject to the provisions of § 15.2-2271 or 15.2-2272 shall not be affected thereby. All public easements, except those for public passage, easements containing improvements, those that contain private utility facilities, common or shared easements for the use of franchised cable operators and public service corporations, may be relocated by recordation of plat or replat signed by the owner of the real property, approved by an authorized official of a locality, regardless of the manner of acquisition or the type of instrument used to dedicate the original easement. In the event the purpose of the easement is to convey stormwater drainage from a public roadway, the entity responsible for the operation of the roadway shall first determine that the relocation does not threaten either the integrity of the roadway or public passage. The clerk shall index the locality as grantor of any easement or portion thereof terminated and extinguished under this section.
