Benchmarks

Definition & Locations

A benchmark is defined as a permanent physical mark of a known elevation point in the field. It is a surveyed marker which provides a point of beginning for determining elevations of other points in a survey.

Benchmark locations are provided at various points throughout the City. For specific benchmark information please view the maps below and get the corresponding number closest to the location where you would like to start your survey. Then, locate that number on the City of Campbell Benchmark Elevations and United States Coast and Geodetic Survey Elevations for the corresponding elevation.

Disclaimer

Benchmark locations and elevations are based primarily from the 1980s survey data.
