CHAPTER 4

SENATE BILL 29

AN ACT TO AMEND CHAPTER 102 OF THE GENERAL STATUTES TO REDEFINE THE OFFICIAL SURVEY BASE FOR THE STATE OF NORTH CAROLINA IN RELATION TO THE NORTH AMERICAN DATUM OF 1983.

The General Assembly of North Carolina enacts:

Section 1.  Chapter 102 of the General Statutes is hereby amended by inserting a new section following G.S. 102-1 to be designated as G.S. 102-1.1 to read as follows:

"§ 102-1.1.  Name and description in relation to the 1983 North American Datum. — From and after the date and time the North Carolina Geodetic Survey Section in the Land Resources Division of the Department of Natural Resources and Community Development receives from the National Geodetic Survey, official notice of a complete, published definition of the North American Datum of 1983 including the State plane coordinate constants applicable to North Carolina, the official survey base for North Carolina shall be a system of plane coordinates to be known as the 'North Carolina Coordinate System of 1983', said system being defined as a Lambert conformal projection of the 'World Reference Ellipsoid' having a central meridian of 79°-00' west from Greenwich and standard parallels of latitude of 34°-20' and 36°-10' north of the equator, along which parallels the scale shall be exact. All coordinates of the system are expressed in metres, the x coordinate being measured easterly along the grid and the y coordinate being measured northerly along the grid. The origin of the coordinates is hereby established on the meridian 79°-00' west from Greenwich at the intersection of the parallels 33°-45' north latitude, such origin being given the coordinates x=600,000 metres, y=0 metres. The precise position of said system shall be as marked on the ground by triangulation or traverse stations or monuments established in conformity with the standards adopted by the National Geodetic Survey for first- and second-order work, whose geodetic positions have been rigidly adjusted on the North American Datum of 1983, and whose plane coordinates have been computed on the system defined."

Sec. 2.  This act is effective upon ratification.

In the General Assembly read three times and ratified, this the 5th day of February, 1979.
