Utah Code Title 57. Real Estate § 57-10-3. North to South and East to West coordinate values

(1) One of these distances, known as the “x-coordinate” or “E-coordinate,” shall give the position in an east-west direction;  the other, known as the “y-coordinate” or “N-coordinate,” shall give the position in a north-south direction.

(2) These coordinates shall be made to depend upon and conform to plane rectangular coordinate values computed on the systems defined in this chapter for the monumented points of the North American Horizontal Geodetic Control Network, as published by the National Ocean Service/National Geodetic Survey (formerly the United States Coast and Geodetic Survey) or its successors.

(3) Any such station may be used for establishing a survey connection to either Utah coordinate system.
