Arkansas Code Title 15. Natural Resources and Economic Development § 15-21-306. Federal definition adopted

(1)(A) The Arkansas Coordinate System 1983, North Zone, is a Lambert conformal projection of the North American Datum of 1983 (NAD83), having standard parallels at north latitudes of thirty-four degrees fifty-six minutes (34° 56′ north) and thirty-six degrees fourteen minutes (36° 14′ north), along which parallels the scale shall be exact.

(B) The origin of coordinates is at the intersection of the meridian ninety-two degrees zero minutes west of Greenwich (92° 00′ west) and the parallel thirty-four degrees twenty minutes north latitude (34° 20′ north). This origin is given the coordinates: East equals four hundred thousand meters (400,000 m.) and north equals zero meters (0.0 m.); and

(2)(A) The Arkansas Coordinate System 1983, South Zone, is a Lambert conformal projection of the North American Datum of 1983 (NAD83), having standard parallels at north latitudes of thirty-three degrees eighteen minutes (33° 18′ north) and thirty-four degrees forty minutes (34° 40′ north), along which parallels the scale shall be exact.

(B) The origin of coordinates is at the intersection of the meridian ninety-two degrees zero minutes west of Greenwich (92° 0′ west) and the parallel thirty-two degrees forty minutes north latitude (32° 40′ north). This origin is given the coordinates: East equals four hundred thousand meters (400,000 m.) and north equals four hundred thousand meters (400,000 m.).
