To assist surveyors working in Jefferson County, we have developed a map showing the Colorado High Accuracy Reference Network (CHARN) and the North American Vertical Datum 1988 (NAVD 88) benchmarks in the county.
The Geodetic survey control was established by the National Geodetic Survey (NGS), Colorado Department of Transportation (CDOT) and Jefferson County.
For complete data sheet information on the CHARN and NAVD 88 networks, please refer to the National Geodetic Survey home page.

Monument records are available from the state of Colorado and from the county clerk and recorder's office.
Since July 1, 1987, land surveys showing property boundaries must be filed with the Jefferson County Clerk and Recorder. Land surveys come in many forms. The most common are land survey plats, improvement survey plats, ALTA surveys and boundary surveys. Subdivision plats are different in that they divide land, typically through a city or county planning process, whereas land survey plats show the existing property boundary and often other land features.
