Survey Control for City of Thornton Projects

Horizontal Control

The City of Thornton does not maintain a survey network.  Please use NGS monuments and/or the Adams County Network for your control points when working on City of Thornton projects.

Vertical Control

The vertical datum must be based upon the North American Vertical Datum 1988 (NAVD 88).  You may use the City of Thornton Benchmarks, which are downloadable below, Benchmarks from NGS and the Adams County Control points.

Benchmark descriptions are now available in a downloadable pdf format.

For information regarding any of these programs can be received by contacting the Infrastructure Department at 720-977-6210 or email Infrastructure.
