Carson City Control Network

Horizontal and Vertical Information (Benchmarks)

The Carson City Control Network is a group of monuments (benchmarks) that have known elevations which are the result of 2nd Order Class 2 survey using a Trimble digital level with invar staves. All level loops were adjusted using network least-squares and the mean relative confidence level (95%) is less than .02ft.

This control network is intended to be used by Surveyors and Engineers for the purposes of setting flood design elevations, filling out elevation certificates or other flood related forms.
