How Alaska Governs Land Surveying
Alaska regulates land surveying through a structured licensing system administered by the state. Alaska Statutes AS 08.48 establishes the framework for professional licensing of land surveyors, architects, and engineers. Only a licensed Professional Land Surveyor (PLS) may perform, certify, or supervise boundary surveys that have legal effect in Alaska. This includes boundary surveys for conveyance, subdivision, dispute resolution, and plat recording.
The Alaska Board of Registration for Architects, Engineers, and Land Surveyors (BOAELS) administers the PLS licensing program. BOAELS sets examination requirements, reviews applications, issues licenses, and takes disciplinary action when licensees violate professional standards. Alaska's PLS licensing requirements align with national standards, including the Fundamentals of Surveying (FS) exam and the Principles and Practice of Surveying (PS) exam administered by the National Council of Examiners for Engineering and Surveying (NCEES).
What a Licensed PLS Can Do
A licensed PLS in Alaska has the authority to perform and certify a broad range of survey types. These include boundary surveys, subdivision surveys, topographic surveys, construction staking, right-of-way surveys, and expert testimony in boundary disputes. The PLS seal on a survey document certifies that the work meets state standards and that the surveyor accepts professional responsibility for its accuracy.
Unlicensed persons may assist with fieldwork under the direct supervision of a PLS, but they may not independently perform or certify boundary surveys. Any survey document bearing the seal of an unlicensed person is not legally valid in Alaska. This distinction matters when property is being bought, sold, subdivided, or when a boundary dispute arises.
Plat Recording Requirements Under AS 34.65
Alaska Statutes Chapter 34.65 governs the platting and subdivision of land. When a parcel is subdivided or when a new lot is created for conveyance, a plat must be prepared by a PLS and recorded with the district recorder. Alaska has several district recording offices, and the requirement to record a plat applies statewide regardless of whether the property is in an organized borough or unorganized territory.
A recordable plat must meet technical standards set by the state, including accurate depiction of boundaries, lot dimensions, easements, rights-of-way, and monument descriptions. The PLS certifies that the survey was conducted in accordance with applicable standards. Plats that do not meet these requirements will be rejected by the district recorder.
For properties being conveyed without subdivision, a boundary survey may not always require a new plat filing. However, if boundary lines are uncertain or if the existing recorded plat is outdated, a new survey is strongly advisable before any transfer occurs.
Corner Monumentation Standards
Alaska has specific requirements for the type, placement, and description of boundary monuments. Monuments must be durable and set in a manner that ensures they will remain stable after installation. In much of Alaska, this means accounting for the effects of freeze-thaw cycles, frost heave, and permafrost.
In Interior Alaska, including the Fairbanks North Star Borough and surrounding areas, permafrost presents a particular challenge. Shallow monuments can be displaced vertically by frost heave within a single winter season. Alaska surveying practice requires that monuments in permafrost zones be set below the active frost layer, which can extend several feet below the surface, to ensure long-term stability. The PLS must document monument type, depth, and material in the survey record.
When existing monuments are found disturbed or missing, the PLS must use available evidence to restore or reestablish them. This includes field evidence, record measurements, witness corners, and bearing trees documented in historical survey records.
The BLM Cadastral System and Alaska Land Surveys
The federal government conducted original land surveys across portions of Alaska using the Public Land Survey System (PLSS). The Bureau of Land Management (BLM) Cadastral Survey program maintains records of these surveys, including General Land Office (GLO) corners and field notes from the original surveys. These records are the legal starting point for boundary surveys in PLSS areas.
However, Alaska is unique among states in that a large portion of its land area has never been formally surveyed under the PLSS. Vast tracts of federal, state, and Alaska Native-owned land remain unsurveyed or only partially surveyed. In these areas, boundary work involves federal and state land status records, Alaska Native Claims Settlement Act (ANCSA) conveyance documents, and other specialized records rather than conventional PLSS corners.
When a PLS works in a PLSS area, the process begins with researching BLM cadastral records to locate the controlling corners for the parcel. The surveyor then searches for those corners in the field, checks their condition, and uses them as the basis for measuring and marking the parcel boundaries. Where BLM corners have been disturbed or destroyed, the PLS applies established procedures for corner restoration based on proportionate measurement and other record evidence.
Federal Land Adjacency and Native Allotment Surveys
Approximately 60 percent of Alaska's land area is federally owned. This means that a large share of private land parcels in Alaska share a boundary with federal land. Federal land adjacency adds a layer of research complexity, since the PLS must work with federal land status records in addition to state and local records. Errors in federal boundary location can have significant consequences for property owners.
Alaska Native allotments are another category of land with specialized survey requirements. These parcels were conveyed to individual Alaska Natives under federal law, and their boundaries are described in federal survey documents. A PLS working near allotment boundaries must research those federal records carefully to avoid errors that could affect Native land rights.
Tidal and Riparian Boundaries
Coastal properties in Alaska frequently involve tidal boundaries. Under Alaska law and federal common law, the boundary between private upland property and tidal land is generally the mean high water line. Determining the mean high water line requires a combination of tidal data, field observation, and legal analysis. A PLS with experience in coastal surveys is essential for any coastal property work.
Riparian boundaries, where a parcel borders a river or stream, are similarly complex. Rivers in Alaska can shift course significantly over time due to glacial melt, flooding, and erosion. The legal boundary may be the ordinary high water mark or another defined feature, and establishing it requires both survey expertise and knowledge of applicable water law.
Boundary Disputes and the Role of a PLS
When property owners disagree about the location of a boundary, a licensed PLS is the appropriate professional to establish the legally correct line based on survey evidence and applicable law. The PLS examines all available evidence, including recorded plats, deeds, field monuments, and historical records, and prepares a survey report documenting the basis for the boundary location.
If a dispute cannot be resolved through the survey process, the matter may go to court. In litigation, the PLS's survey report and testimony serve as expert evidence. Courts rely on licensed surveyors to interpret complex boundary evidence and apply established surveying principles to determine the correct boundary location.
