(1) For the
purposes of more precisely defining the Colorado coordinate system of 1927, the
following definitions by the United States coast and geodetic survey (now the
national ocean survey/national geodetic survey) are adopted:

(a) The Colorado coordinate system of 1927 north zone is a Lambert
conformal conic projection of the Clarke spheroid of 1866, having standard
parallels at north latitudes 39 degrees 43 minutes and 40 degrees 47 minutes
along which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 105 degrees 30 minutes west of Greenwich and the
parallel 39 degrees 20 minutes north latitude. This origin is given the coordinates: x
- 2,000,000 feet and y - 0 feet.

(b) The Colorado coordinate system of 1927 central zone is a Lambert
conformal conic projection of the Clarke spheroid of 1866, having standard
parallels at north latitudes 38 degrees 27 minutes and 39 degrees 45 minutes
north latitude along which parallels the scale shall be exact. The origin of
coordinates is at the intersection of the meridian 105 degrees 30 minutes west of
Greenwich and the parallel 37 degrees 50 minutes north latitude. This origin is
given the coordinates: x - 2,000,000 feet and y - 0 feet.

(c) The Colorado coordinate system of 1927 south zone is a Lambert
conformal conic projection of the Clarke spheroid of 1866, having standard
parallels at north latitudes 37 degrees 14 minutes and 38 degrees 26 minutes
along which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 105 degrees 30 minutes west of Greenwich and the
parallel 36 degrees 40 minutes north latitude. This origin is given the coordinates: x
- 2,000,000 feet and y - 0 feet.

(2) For the purposes of more precisely defining the Colorado coordinate
system of 1983, the following definition by the national ocean service/national
geodetic survey is adopted:

(a) The Colorado coordinate system of 1983 north zone is a Lambert
conformal conic projection of the North American datum of 1983, having standard
parallels at north latitude of 39 degrees 43 minutes and 40 degrees 47 minutes
along which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 105 degrees 30 minutes west of Greenwich and the
parallel 39 degrees 20 minutes north latitude. This origin is given the coordinates: x
- 914,401.8289 meters and y - 304,800.6096 meters.

(b) The Colorado 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 38 degrees 27 minutes and 39 degrees 45 minutes
along which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 105 degrees 30 minutes west of Greenwich and the
parallel 37 degrees 50 minutes north latitude. This origin is given the coordinates: x
- 914,401.8289 meters and y - 304,800.6096 meters.

(c) The Colorado 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 37 degrees 14 minutes and 38 degrees 26 minutes
along which parallels the scale shall be exact. The origin of coordinates is at the
intersection of the meridian 105 degrees 30 minutes west of Greenwich and the
parallel 36 degrees 40 minutes north latitude. This origin is given the coordinates: x
- 914,401.8289 meters and y - 304,800.6096 meters.
