Va. Code § 10.1-2207
Where the Commonwealth has obtained from a landowner an easement or other partial interest in property which places restrictions on the use or development of that property so as to preserve those features which led to the designation of that property as an historic landmark, the easement or other partial interest shall be recorded in the clerk's office of the county or city where deeds are admitted to record. Assessments for local taxation of the property shall reflect any resulting change in the market value of the property, as prescribed by § 58.1-3205. The Director shall notify the official having the taxing power to make assessments of properties for purposes of taxation within the locality of the restrictions that have been placed on the property.
