The NGS Bench Mark Reset Guidelines provide the necessary information to
preserve elevation data for a soon-to-be disturbed or soon-to-be
destroyed bench mark. Bench marks provide a continuous record of
elevation changes, as well as vertical control for many local
surveyors, and their preservation is vital. It is imperative that
elevation information be transferred or referenced from the original
bench mark prior to its being disturbed or destroyed. The support and
cooperation of local surveyors and engineers in this endeavor is not
only important, but essential to the preservation of bench marks. The
guidelines are located here Reset
guidelines.
