§ 1-605. (For contingent expiration date, see Acts 2025, cc. 91 and 109, cl. 2) Definition of systems by National Ocean Service/National Geodetic Survey; adopted.
A. For purposes of more precisely defining the Virginia Coordinate System of 1927, the following definition by the National Ocean Service/National Geodetic Survey is adopted:
The Virginia Coordinate System of 1927, North Zone, is a Lambert conformal projection of the Clarke spheroid of 1896, having standard parallels at north latitudes 38° 02' and 39° 12', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich with the parallel 37° 40' north latitude, such origin being given the coordinates: x = 2,000,000', and y = 0'.
The Virginia Coordinate System of 1927, South Zone, is a Lambert conformal projection of the Clarke spheroid of 1896, having standard parallels at north latitudes 36° 46' and 37° 58', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich with the parallel 36° 20' north latitude, such origin being given the coordinates: x = 2,000,000', and y = 0'.
B. For purposes of more precisely defining the Virginia Coordinate System of 1983, the following definition by the National Ocean Service/National Geodetic Survey is adopted:
The Virginia Coordinate System of 1983, North Zone, is a Lambert conformal conic projection based on the North American Datum of 1983, having standard parallels at north latitudes 38° 02' and 39° 12', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich and the parallel 37° 40' north latitude, such origin being given the coordinates: x = 3,500,000 meters and y = 2,000,000 meters.
The Virginia Coordinate System of 1983, South Zone, is a Lambert conformal conic projection based on the North American Datum of 1983, having standard parallels at north latitudes 36° 46' and 37° 58', along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 30' west of Greenwich and the parallel 36° 20' north latitude, such origin being given the coordinates: x = 3,500,000 meters and y = 1,000,000 meters.

C. For purposes of more precisely defining the Virginia Coordinate System of 2022, the following definition by the National Ocean Service/National Geodetic Survey is adopted:
The Virginia Coordinate System of 2022, North Zone, is a Lambert conformal conic, one parallel projection based on the North American Terrestrial Reference Frame of 2022, having one standard parallel at north latitude 38° 36', along which parallel the scale shall be exact. The origin of coordinates is at the intersection of the meridian 78° 15' west of Greenwich and the parallel 38° 36' north latitude, such origin being given the coordinates: x = 457,200 meters and y = 190,500 meters.
The Virginia Coordinate System of 2022, South Zone, is a Lambert conformal conic, one parallel projection based on the North American Terrestrial Reference Frame of 2022, having one standard parallel at north latitude 37° 21', along which parallel the scale shall be 0.999990. The origin of coordinates is at the intersection of the meridian 79° 30' west of Greenwich and the parallel 37° 21' north latitude, such origin being given the coordinates: x = 685,800 meters and y = 190,500 meters.
