Overview
The County Surveyor is the licensed professional responsible for the accuracy and integrity of the official land boundary record within the county. That sounds technical, but the practical implications touch almost every piece of property in the jurisdiction: when two neighbors disagree about where the fence line belongs, when a road department needs to know whether a driveway is in the right-of-way, when a title company finds a gap in the legal description of a parcel, the County Surveyor's records are the starting point for resolution.
The core infrastructure the County Surveyor maintains is the monument system — the physical markers that define the corners of the Public Land Survey System in PLSS states, and the network of permanent benchmarks and control points in all counties. These monuments are the original references from which every property boundary is legally measured. Finding, verifying, restoring, and recording them is painstaking work that requires both field skills and deep knowledge of historical survey practice.
Subdivision review is the other major recurring function. When a developer wants to divide land into lots, the County Surveyor reviews the plat for technical accuracy: whether the boundary descriptions close mathematically, whether the monuments match the record, whether the legal descriptions are internally consistent. Approving a flawed plat creates problems that persist in the county's land records indefinitely.
The County Surveyor also serves as a technical resource for the rest of county government — the road department, the assessor's office, the planning department, and the county attorney all regularly need information about boundaries, rights-of-way, and the legal descriptions of county-owned property. In smaller counties, the surveyor may handle all of this personally. In larger counties, a staff of survey technicians and field crews works under the surveyor's direction.

Career outlook
The County Surveyor position is a stable niche within public sector employment. The statutory need for the function is not going away — every real estate transaction, every infrastructure project, and every boundary dispute in the county depends on a functioning official survey record system.
At the same time, the workforce pipeline for licensed land surveyors is a persistent concern. Surveying programs at community and technical colleges have declined in number over the past two decades. The PLS licensing pathway is long — four to eight years of supervised experience after an exam that requires significant preparation. The result is a shortage of qualified surveyors that affects both private practice and county positions. This shortage keeps compensation at or above comparable civil service positions and gives experienced PLS holders genuine leverage in hiring negotiations.
Technology has not reduced the need for licensed surveyors — it has changed what they do. GPS, LiDAR, and unmanned aerial systems have expanded what a surveyor can measure and document, but interpreting boundary evidence, adjudicating conflicting deed descriptions, and restoring lost monuments require professional judgment that technology does not replace. Counties that have invested in drone-based topographic mapping and GPS control networks are more productive, not less reliant on licensed surveyors.
For PLS holders considering the public sector, county surveying offers a career with clear professional scope, meaningful public impact, and the permanence of institutional infrastructure work. The advancement path is relatively flat — most county surveyor offices are small — but lateral moves into state DOT, Bureau of Land Management, or Army Corps of Engineers positions are common and offer both scale and salary advancement.
Sample cover letter
Dear [County Board / Hiring Manager],
I am applying for the position of County Surveyor for [County] County. I am a Licensed Professional Land Surveyor with 12 years of experience in boundary surveying, PLSS corner perpetuation, and subdivision review.
For the past seven years I have worked as a senior surveyor with [Firm], where a significant portion of my practice has been county-agency work including corner restoration contracts for [County A] and [County B] Counties. I have established and recorded over 400 section corner certificates in that work, including several disputed corners that required multi-day field investigations to resolve through GLO field notes and chain-of-title analysis.
I hold a current [State] PLS license (No. [XXXXX]) and am familiar with the corner perpetuation and filing act requirements specific to this state. I have appeared as an expert witness in three boundary dispute proceedings and have direct experience preparing testimony that juries and judges without survey backgrounds can follow.
My interest in the County Surveyor position is specific: I want to build and maintain the county's monument database in a systematic, defensible way that will serve property owners and title professionals for the next generation. The ad hoc approach that many smaller county offices use — documenting corners when disputes arise rather than on a planned maintenance schedule — creates unnecessary risk and eventually generates the disputes it was designed to avoid.
I would welcome the opportunity to discuss the county's current monument maintenance program and where I could contribute most directly.
[Your Name], PLS
Frequently asked questions
- Is the County Surveyor elected or appointed?
- It depends on the state. Many western states with township-and-range cadastral survey systems elect their county surveyors. Other states use civil service appointment. In states where the position is elected, candidates must be licensed Professional Land Surveyors (PLS) in most states, though a few older statutes allowed non-licensed candidates historically.
- What is the PLSS and why does the County Surveyor deal with it?
- The Public Land Survey System (PLSS) is the rectangular survey grid established by the federal government in the late 1700s that divides most of the western United States into townships, sections, and quarter-sections. Section corners are the physical monuments that define this grid on the ground. County surveyors in PLSS states are responsible for locating, restoring, and recording these corners — the reference points from which all private property boundaries in the county ultimately derive.
- What license does a County Surveyor need?
- A Professional Land Surveyor (PLS) license issued by the state is required in most jurisdictions. PLS licensure requires a combination of education (bachelor's in surveying or related field), passage of the Fundamentals of Surveying (FS) and Principles and Practice of Surveying (PS) exams administered by NCEES, and a supervised work experience period typically ranging from four to eight years depending on education level.
- How is GPS and LiDAR changing county surveying?
- GPS-based survey-grade equipment has largely replaced optical instruments for control work and most boundary surveys. LiDAR from aircraft and drones now produces topographic data at accuracy levels that previously required extensive ground crews. These tools have dramatically increased the speed and coverage of survey work. The County Surveyor's role has shifted toward managing data quality, maintaining geodetic control, and interpreting modern datasets in the context of historical boundary evidence.
- What happens when a county doesn't fill the surveyor position?
- In states where the position is required by statute, the county must contract with private licensed surveyors for the work the surveyor would perform, or petition the state to have the duties reassigned. Monument maintenance programs are often the first casualty — corner restoration work falls behind without dedicated staff. The long-term consequence is degraded boundary accuracy county-wide, which generates downstream problems for property owners, title companies, and developers.
