A county surveyor is a public official in many counties of the USA. At the bottom of this page are working "External Links" as at 4 November 2011 to websites of a selection of such County Surveyor's departments. Most of these officials are elected on the partisan ballot to four-year terms. They administer the county land survey records, re-establish and maintain the official government survey monuments, and review property boundaries surveys and subdivision plans. Other duties vary from state to state. Those marked with an asterisk (*) are nominated by the National Association of County Surveyors (NACS).
