For CCS27, the state is divided into seven zones. For CCS83, the state is divided into six zones. Zone 7 of CCS27, which encompasses Los Angeles County, is eliminated and the area is included in Zone 5 of CCS83.
Each zone of CCS27 is a Lambert conformal conic projection based on Clarke’s Spheroid of 1866, which is the basis of NAD27. The points of control of zones one to six, inclusive, bear the coordinates: Northing
(y)= 000.00 feet and Easting
(x)= 2,000,000 feet. The point of control of Zone 7 bears the coordinates: Northing
(y)= 4,160,926.74 feet and Easting
(x)= 4,186,692.58 feet.
Each zone of CCS83 is a Lambert conformal conic projection based on the Geodetic Reference System of 1980, which is the basis of NAD83. The point of control of each of the six zones bear the coordinates: Northing
(y)= 500,000 meters and Easting
(x)= 2,000,000 meters.
