Who Governs Land Surveying in Wyoming?
Land surveying in Wyoming is regulated by the Wyoming State Board of Registration for Professional Engineers and Professional Land Surveyors, commonly known as WSBOREPLS. The board operates under Wyoming Statutes Title 33, Chapter 29 (W.S. 33-29), which defines who may practice surveying, what constitutes the practice of land surveying, and the consequences of practicing without a license.
Only a person holding a Professional Land Surveyor (PLS) license issued by WSBOREPLS may perform or offer to perform boundary surveys in Wyoming. The PLS credential requires passing the Fundamentals of Surveying and Principles and Practice of Surveying examinations, meeting education and experience requirements, and maintaining good standing with the board. You can search for licensed PLS professionals in our Wyoming surveyor directory.
What Requires a Licensed PLS in Wyoming?
Wyoming law draws a clear line between work that requires a PLS license and work that does not. The following activities require a licensed PLS:
- Any survey that establishes, re-establishes, or locates a property boundary
- Subdivision plat preparation and recording
- Surveys that create or alter parcels of land
- Oil and gas well location surveys
- Topographic surveys used for engineering or land development purposes when they involve boundary determination
- ALTA/NSPS Land Title Surveys
Unlicensed persons may assist a licensed PLS in the field, but the PLS must supervise the work, review all data, and apply their seal and signature to any final survey document. Practicing land surveying without a license is a violation of W.S. 33-29 and can result in civil and criminal penalties.
Plat Recording Requirements
When a boundary survey creates a new parcel or alters an existing one, Wyoming requires that the survey be memorialized in a recorded plat or survey map. The document must be prepared and sealed by a licensed PLS and filed with the county clerk in the county where the land is located. Once recorded, the plat becomes the legal reference for the property boundaries described within it.
For subdivisions, additional review by county planning and engineering departments is typically required before a plat can be recorded. The specific requirements vary by county, so the licensed PLS handling the work will coordinate that process.
The Public Land Survey System in Wyoming
Wyoming is entirely described using the Public Land Survey System (PLSS), the rectangular grid of townships, ranges, and sections established by the federal government beginning in the late 1700s. In Wyoming, U.S. General Land Office (GLO) surveyors laid out this grid during surveys conducted primarily in the late 1800s and early 1900s. Every legal description for land in the state references a township (north or south of a baseline), a range (east or west of a principal meridian), and a section (one of 36 one-square-mile blocks within a township).
Finding the actual location of a property line on the ground requires locating the original GLO corners that define those township and section lines. In Wyoming's varied terrain, including high-altitude meadows, sagebrush plains, and rugged mountain ranges, these corners may be buried, disturbed, or simply difficult to find without the specialized equipment and record research skills that a licensed PLS brings to the work.
BLM Cadastral Surveys and Federal Land Context
Roughly half of Wyoming's land area is federally owned and managed by agencies including the Bureau of Land Management (BLM), the U.S. Forest Service, and the National Park Service. This extensive federal ownership has practical consequences for boundary surveys conducted anywhere near federal land.
The BLM Cadastral Survey program maintains records of the original GLO survey notes and plats, as well as subsequent dependent resurveys conducted to restore lost or obliterated corners. When a Wyoming PLS performs a boundary survey adjacent to or involving federal land, researching BLM cadastral records is an essential step. Those records document the original survey intent and any subsequent government-authorized corner restorations.
Boundary disputes involving federal land may require coordination with BLM and can involve both state law and federal regulations. A PLS experienced in Wyoming's federal land context is particularly valuable for ranch properties, energy leases, and other parcels that border or include federal acreage.
Oil and Gas Survey Requirements
Wyoming's energy industry generates substantial demand for specialized survey services. Well location surveys are among the most common. State and federal regulations require that the location of each oil or gas well be documented by a licensed PLS relative to PLSS section lines and lease boundaries before drilling commences and after the well is completed. This ensures that wells are drilled within the correct lease boundaries and that production can be allocated accurately.
Beyond well locations, energy-related boundary work in Wyoming includes pipeline corridor surveys, surface use agreement boundary staking, and access road surveys. Mineral rights boundaries, which in Wyoming often differ from surface ownership boundaries, are also described using PLSS references and require PLS expertise to locate and document.
Monuments and Corner Records
Wyoming law and professional standards require that monuments be set at property corners established by a boundary survey. Monuments may be iron pipes, rebar, or other durable markers, and their type and location must be documented in the survey record. When a PLS discovers an existing original GLO monument during a survey, they are expected to note its condition and location in the survey record rather than disturb or replace it without cause.
If a GLO corner has been destroyed or cannot be found, a PLS may restore it through a dependent resurvey process that references BLM cadastral records and surviving adjacent corners. The restored corner is then documented and the record may be filed with the county or the BLM, depending on the circumstances.
Boundary Disputes in Wyoming
When neighboring landowners disagree about the location of a shared property line, the dispute is ultimately resolved by reference to the recorded legal descriptions, original survey records, and the physical monuments set by licensed surveyors. Wyoming courts have jurisdiction over boundary disputes, and a survey prepared by a licensed PLS is generally required to support any legal claim about where a boundary lies.
It is worth understanding that a fence line, no matter how long-standing, is not a legal property boundary in Wyoming unless it has been recognized as such through a legal process such as acquiescence or adverse possession. An old fence placed by a rancher decades ago may deviate significantly from the true PLSS section line. Only a licensed PLS can determine where the legal boundary actually lies.
