Virginia Code Title 1. General Provisions § 1-606. Position of systems

The position of the Virginia coordinate systems shall be as marked on the ground by triangulation or traverse stations established in conformity with the standards of accuracy and specifications for first-order and second-order geodetic surveying as prepared and published by the Federal Geodetic Control Subcommittee of the Federal Geographic Data Committee of the U.S. Department of Commerce.  The geodetic position of stations defining the position of the Virginia Coordinate System of 1927 shall have been rigidly adjusted on the North American Datum of 1927, and the plane coordinates shall have been computed on the Virginia Coordinate System of 1927.  The geodetic position of stations defining the position of the Virginia Coordinate System of 1983 shall have been rigidly adjusted on the North American Datum of 1983, and the plane coordinates shall have been computed on the Virginia Coordinate System of 1983.  Any such station may be used for establishing a survey connection with the Virginia coordinate systems.
