S.B. 41 Enrolled
This act modifies the Utah Coordinate System. The act adopts special publications to more
precisely define the Utah Coordinate Systems of 1927 and 1983. The act modifies the
requirements for any document identifying or using a coordinate system. The act establishes
that, in addition to the Utah Coordinate System of 1983, any person, corporation, municipality,
county, or state agency establishing a new coordinate network must conform to the current
federal coordinate update.
This act affects sections of Utah Code Annotated 1953 as follows:

Section 1. Section 57-10-6 is amended to read:
57-10-6. Utah Coordinate Systems of 1927 and 1983 defined.
[
the following [
(1) For the Utah Coordinate System of 1927, the manual entitled "The State Coordinate
Systems (A Manual for Surveyors)," Special Publication No. 235, and "Plane Coordinate Projection
Tables for Utah," Special Publication No. 277. Both manuals are published by the U.S. Department
of Commerce, Coast and Geodetic Survey, and provide, in part, the following:
(a) (i) The "Utah Coordinate System of 1927 North Zone" is a Lambert Conformal Conic
Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 41 degrees 47
minutes and 40 degrees 43 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west of
Greenwich and the parallel 40 degrees 20 minutes north latitude.
(iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
(b) (i) The "Utah Coordinate System of 1927 Central Zone" is a Lambert Conformal Conic
Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 40 degrees 39
minutes and 39 degrees 01 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west of
Greenwich and the parallel 38 degrees 20 minutes north latitude.
(iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
(c) (i) The "Utah Coordinate System of 1927 South Zone" is a Lambert Conformal Conic
Projection of the Clarke Spheroid of 1866 having standard parallels at north latitudes 38 degrees 21
minutes and 37 degrees 13 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west of
Greenwich and the parallel 36 degrees 40 minutes north latitude.
(iii) This origin is given the coordinates: x=2,000,000 feet and y=0 feet.
(2) For [
entitled "State Plan Coordinate System of 1983," NOAA Manual NOS NGS 5. The manual is published
by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, and provides,
in part, the following [
(a) (i) The "Utah Coordinate System of 1983 North Zone" is a Lambert Conformal Conic
Projection of the North American Datum of 1983 having standard parallels at north latitudes 41 degrees
47 minutes and 40 degrees 43 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west of
Greenwich and the parallel 40 degrees 20 minutes north latitude.
(iii) This origin is given the coordinates: x or E=500,000 meters and y or N=1,000,000 meters.
(b) (i) The "Utah Coordinate System of 1983 Central Zone" is a Lambert Conformal Conic
Projection of the North American Datum of 1983 having standard parallels at north latitudes 40 degrees
39 minutes and 39 degrees 01 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west
Greenwich and the parallel 38 degrees 20 minutes north latitude.
(iii) This origin is given the coordinates: x or E=500,000 meters and y or N=2,000,000 meters.
(c) (i) The "Utah Coordinate System of 1983 South Zone" is a Lambert Conformal Conic
Projection of the North American Datum of 1983 having standard parallels at north latitudes 38 degrees
21 minutes and 37 degrees 13 minutes, along which parallels the scale shall be exact.
(ii) The origin of coordinates is at the intersection of the meridian 111 degrees 30 minutes west of
Greenwich and the parallel 36 degrees 40 minutes north latitude.
(iii) This origin is given the coordinates: x or E=500,000 meters and y or N=3,000,000 meters.
Section 2. Section 57-10-8 is amended to read:
57-10-8. Use of terms on maps and documents.
(1) Any document identifying or using a coordinate system shall, in accordance with Section
57-10-9 , clearly and completely identify the system used.
[
any map, report of survey, or other document [
coordinates [
Subsection 57-10-6 (1).
(b) The use of the term "Utah Coordinate System of 1983 (HARN 1994, or the current federal
coordinate update used as the basis of the system being used) (North, Central, South) Zone" shall be used
to reference the system, the coordinates, and the unit of measure as defined in Subsection 57-10-6 (2).
(2) Anyone using a coordinate system similar to the Utah coordinate system, such as one where
a modified elevation datum is used, shall clearly include "modified" in the title of the coordinate system.
(3) Any survey or map based on any such modified coordinate system shall show the title of the
coordinate system, including "modified" in the title and show the appropriate combined adjustment factor
relating the system to the Utah coordinate system.
Section 3. Section 57-10-9 is amended to read:
57-10-9. Use of coordinate system optional.
The use of the Utah coordinate system by any person, corporation, or governmental agency
engaged in land surveying or mapping, or both, is optional.
Section 4. Section 57-10-11 is amended to read:
57-10-11. 1983 system to be used after certain dates.
After [
state agency who is not utilizing an existing county coordinate system and is establishing a new countywide
coordinate network [
must conform to the Utah Coordinate System of 1983[
coordinate update.
Section 5. Repealer.
This act repeals:
Section 57-10-10, Feet to meters conversion specified.
