County Surveyor Job Description

A County Surveyor runs the county's boundary infrastructure. That means the physical monuments that mark section corners, quarter corners and subdivision corners, plus the paper and digital trail that tells the next surveyor where those monuments are and how they were established. When a fence dispute, a road widening or a mapping error reaches county government, the surveyor's office holds the evidence everyone else depends on.

Corner perpetuation

The core of the job is keeping corners alive. Monuments get buried by grading, knocked out by farm equipment and paved over by road crews. The County Surveyor's office searches for them with original field notes and bearing-tree or accessory descriptions, digs, measures, and when the evidence supports it, sets a new monument with fresh reference ties. Indiana writes this into statute: Indiana Code 36-2-12-11 directs the county surveyor to keep a corner record book indexed by location and, each year, to check and reference at least five percent of all corners shown in it. The same section lets the surveyor enter findings submitted by private registered surveyors who check and reference corners, and it allows money in the county surveyor's corner perpetuation fund to pay for the work.

Road work is the other constant threat. California's Professional Land Surveyors' Act, as summarized in the County Engineers Association of California filing guide, requires monuments to be located and referenced by a licensed surveyor or authorized civil engineer prior to the time when streets, highways or easements are improved, constructed or resurfaced, with a corner record or record of survey of the references filed with the county surveyor. The county surveyor's office receives those filings and can check that the reset monuments match the record.

Map checking and records

Review fills the rest of the week. Subdivision plats, parcel maps, lot line adjustments and records of survey come in from private firms, and the county surveyor's staff checks that the boundaries close, that monuments called for were actually found or set, and that the drawing conforms to the state's map act and local ordinance. Deficient maps go back with correction letters. Approved ones become part of the permanent record.

Working with the rest of the county

The surveyor is the technical reference for the assessor, the recorder, the road department and the county attorney. Corrected corner coordinates flow into the parcel GIS so tax maps line up with monuments on the ground. Right-of-way questions from the highway department, legal description reviews for county property purchases, and testimony in boundary litigation all route through this office. In a small county the surveyor may do nearly all of it personally with one technician; in a large urban county the office can include map-check engineers, field crews, GIS analysts and records clerks under the surveyor's direction.

Licensure

Plan on a state professional land surveyor license. The license is issued by the state board, but the two national exams come from the National Council of Examiners for Engineering and Surveying (NCEES): the Fundamentals of Surveying (FS) exam, typically taken near the end of a degree program, and the Principles and Practice of Surveying (PS) exam, taken after the required supervised experience. A board may add its own state-specific exam on local law, PLSS rules or metes-and-bounds practice. Passing the FS can earn a surveyor-in-training or land surveyor-in-training designation; each board sets the exact title.

Where the office is elected, whether the officeholder must be licensed is a question of that state's county officer law, so read the statute before filing to run. The license and the office are separate things.

Education

As a rough guide, the path runs through a bachelor's degree in surveying, geomatics or civil engineering with a surveying emphasis, which can shorten the experience requirement. Some boards accept an associate degree or long field experience in place of a four-year degree, with more supervised years required. Coursework in boundary law, geodesy, least squares adjustment and GIS pays off directly in a county office.

Experience

Typical candidates for a county surveyor or deputy county surveyor job have spent, as a rough guide, five to ten years in boundary and PLSS work after licensure or near it, including time as a party chief and in map preparation. Experience on the receiving side of county map checking, or inside a county or state DOT survey unit, transfers directly. Candidates for elected offices also need enough administrative skill to write a budget, supervise staff and explain technical decisions to county commissioners.

Additional credentials

• Certified GIS Professional (GISP), awarded by the GIS Certification Institute, for surveyors who also run or oversee the parcel GIS.
• Certified Federal Surveyor (CFedS), a Bureau of Land Management program for surveyors who work on federal interest lands.

Technical skills

• Reading Government Land Office field notes and township plats, and applying federal and state rules for restoring lost and obliterated corners
• GNSS static and RTK methods, total station traverses, and network adjustment software
• Civil 3D or similar CAD for plat review, plus ArcGIS for parcel and corner layers
• Writing and interpreting aliquot, lot-and-block and metes-and-bounds descriptions
• State statutes on corner records, records of survey, subdivision maps and monument preservation

Pay

The best national pay benchmark for this job is the BLS figure for surveyors working in local government, excluding schools and hospitals. In May 2025 that group earned a median of $89,190, with $53,610 at the 10th percentile and $130,670 at the 90th, based on an estimated 2,650 jobs. For comparison, the national Surveyors occupation, which covers all industries, had a May 2025 median of $75,440 across 50,830 jobs. BLS does not report county surveyors separately, the local government row also covers city survey staff, and pay for an elected county surveyor is set locally. A single county's posted salary is only an example, not a national benchmark.

The record is going digital

One change in some county survey offices is the move from paper corner books and tax maps to a single parcel GIS tied to surveyed control. San Bernardino County, Calif., announced on May 14, 2026 that a project involving the Public Works Department's County Surveyor and the Assessor-Recorder-County Clerk had moved decades of parcel records into an Esri Parcel Fabric covering more than 820,000 parcels. That kind of project puts the County Surveyor's corner coordinates at the center of the county's mapping, because parcel lines can only be as accurate as the monuments they are adjusted to.

Federal data work points the same way. The Bureau of Land Management issued manual section MS-9690 on March 23, 2026, covering its PLSS Data Set, the GIS representation of the Public Land Survey System. The manual describes reviewing data provided to BLM by sources that include states, counties and tribes, so data from counties is among the material BLM reviews for the national PLSS layer.

AI and automation

At its 2025 annual meeting, the NCEES Council voted to adopt a position statement on the Responsible Use of Artificial Intelligence in Engineering and Surveying. NCEES is made up of 69 licensing boards that regulate engineering and surveying in the United States. For a County Surveyor, the practical effect is that software can help digitize field notes, index scanned plats or flag map closures, while the decision about whether a stone is the original corner remains a licensed, signed judgment.

Career paths

A County Surveyor position sits at the top of a small office, so advancement can mean moving to a larger county, to a state DOT survey unit, or to a federal cadastral program, or by running for an elected surveyor's office where the state provides one. Deputy county surveyor and map-check jobs are one way into public practice for licensed surveyors. In states such as Indiana the office is written into the state constitution, so the question each budget cycle is how much corner restoration the county funds, not whether the office exists.

Dear Members of the Hiring Committee,

I am applying for the County Surveyor position with Willow Fork County. I hold a professional land surveyor license and have spent the last eight years as deputy county surveyor in a neighboring rural county, where I run the corner restoration program and the map-check desk.

Our corner program is where I have done my most durable work. I took over a corner record book that still lived on index cards, set up a field schedule that sends a two-person crew out every week from April through November, and rewrote our tie-sheet template so every restored corner carries photographs, reference ties and the GNSS observation log. Private surveyors now tell us they can find our monuments on the first visit, which was not true when I started.

On the review side, I check subdivision plats, records of survey and lot line adjustments against state statute and our county ordinance. I write correction letters that cite the specific requirement, and I keep a short list of the errors I see most so I can walk local firms through them before they submit. Turnaround dropped once firms knew what we would ask for.

I also work closely with our GIS coordinator. When we restore a corner, I send the new coordinates and the evidence summary to GIS the same week, and we adjust the parcel layer together. That partnership has made our tax maps far easier to defend at the assessor's counter.

Willow Fork's road program is expanding, and I would bring a practice of meeting with highway staff before each paving season to reference threatened monuments. I would welcome the chance to talk about how I would run your office.

Sincerely, Dana Whitcomb, PLS
