2026 ALTA/NSPS - Utility Locating, Table A Item 11(b)
The release of the 2026 ALTA/NSPS Minimum Standard Detail Requirements marks one of the more operationally important updates to the ALTA standard in recent years—particularly for land surveyors, title professionals, civil engineers, utility consultants, and Subsurface Utility Engineering (SUE) providers.
While many revisions appear administrative or clarifying on the surface, the 2026 standards significantly sharpen expectations surrounding:
- Utility evidence documentation
- Easement interpretation
- Observed underground utility indicators
- Access and encroachment reporting
- Survey defensibility
- Table A Item 11(b) private utility locating workflows
For firms performing ALTA surveys, the practical implication is clear: utility coordination and subsurface utility evidence are no longer peripheral concerns. They are now more deeply integrated into the surveyor’s duty to observe, document, reconcile, and communicate risk.
For companies like US360VIEW, this evolution aligns directly with the increasing need for high-quality private utility locating, utility mapping, SUE support, and field-to-survey integration services.
The Big Picture: What Changed in 2026?
The 2026 ALTA/NSPS revisions are less about reinventing the standard and more about tightening ambiguity.
The updated language repeatedly emphasizes:
- professional judgment,
- observable evidence,
- documentation transparency,
- utility-related risk communication,
- and clearer survey deliverables.
Several revisions directly impact how surveyors approach underground utility evidence and how utility locating consultants support ALTA deliverables.
The most meaningful changes include:
- Expanded clarification of utility evidence requirements
- Stronger language regarding undocumented utility use
- Greater emphasis on observable field conditions
- Clarified treatment of utility locate markings
- Expanded reporting obligations for easements and encroachments
- New summary-table requirements for conflicts and encroachments under Table A Item 20
- Refined expectations regarding imagery, precision, and defensibility
Why Utility Locating Matters More Under the 2026 Standard
The 2026 standards continue reinforcing an important legal and professional distinction:
ALTA surveys are not utility locate surveys.
However, the standards now more clearly acknowledge that utility evidence plays a critical role in identifying:
- easement usage,
- undocumented prescriptive rights,
- access conflicts,
- encroachments,
- and risk exposure affecting title.
This becomes especially important in dense commercial corridors, industrial sites, petrochemical facilities, campuses, airports, municipalities, hospitals, and legacy utility corridors where undocumented infrastructure is common.
The revised standards repeatedly reference:
- utility service lines,
- utility locate markings,
- valves,
- cleanouts,
- pedestals,
- transformers,
- overhead lines,
- pipelines,
- vent pipes,
- and observable utility indicators.
These references are intentionally broader and more descriptive than prior editions.
Section 5.E: The Most Important Utility-Related Revisions
The most significant utility-related language appears in Section 5.E.
The 2026 revision expands and clarifies the surveyor’s responsibility to identify evidence of:
- documented easements,
- undocumented utility use,
- surface indicators of underground facilities,
- and observable utility infrastructure.
The standard now specifically references:
- utility locate markings,
- utility service lines,
- fiber optic lines,
- pipelines,
- water lines,
- sewer lines,
- transformers,
- valves,
- pedestals,
- utility poles,
- and overhead utility indicators.
This matters because many ALTA surveys historically underrepresented utility risk by limiting utility evidence to obvious surface structures.
The 2026 standard now makes it harder to ignore observable indicators that may suggest:
- undocumented utility corridors,
- abandoned infrastructure,
- private utility systems,
- conflicting easement use,
- or encroachments.
Utility Locate Markings Are Now Explicitly Recognized
One of the most operationally important revisions is the explicit inclusion of utility locate markings as observable evidence.
The standard repeatedly references:
“utility locate markings (including the source of the markings, with a note if unknown)”
This is substantial.
It formally acknowledges that utility locating activities are part of the observable evidence ecosystem supporting ALTA survey interpretation.
For surveyors, this creates several implications:
- Locate markings should be documented when present.
- The source of markings should be identified when known.
- Unknown markings should still be noted.
- Utility evidence now has stronger linkage to easement interpretation and risk disclosure.
This also elevates the importance of professionally performed private utility locating.
Understanding Table A Item 11(b)
Table A Item 11 remains the primary mechanism for integrating underground utility information into an ALTA survey.
Under the 2026 standards, Item 11 still distinguishes between:
- 11(a): utility information from plans/reports
- 11(b): markings coordinated through private utility locating
The revised standard states:
“markings coordinated by the surveyor or client pursuant to a private utility locate request.”
This language is critically important because it explicitly recognizes private utility locating—not merely public 811 ticket responses—as part of the ALTA workflow.
What Surveyors Actually Need to Do for 11(b)
When Table A Item 11(b) is requested, surveyors are expected to coordinate or incorporate utility locate information obtained through private utility locating services.
Practically, this usually includes:
1. Coordinating a Private Utility Locate
This often involves hiring a qualified private utility locating company such as US360VIEW to perform:
- electromagnetic utility locating,
- GPR investigations,
- utility tracing,
- utility designation,
- utility mapping,
- and utility evidence documentation.
2. Incorporating Field Markings Into the Survey
The surveyor must then integrate observed utility markings and supporting documentation into the ALTA deliverable.
This may include:
- paint markings,
- flags,
- utility alignments,
- field sketches,
- CAD utility overlays,
- GPS utility mapping,
- and interpreted subsurface corridors.
3. Identifying Sources of Utility Information
The 2026 standards specifically require notation regarding the source of utility markings when known.
That means survey deliverables should identify whether utility evidence originated from:
- public 811 response,
- private locator designation,
- utility owner records,
- as-built plans,
- SUE investigations,
- or field observation.
4. Understanding the Limitation Clause
The standards still maintain an important disclaimer:
“lacking excavation, the exact location of underground features cannot be accurately, completely, and reliably depicted.”
This language protects surveyors from implying absolute certainty regarding buried infrastructure.
However, it also reinforces why professional utility locating matters.
Better utility evidence reduces uncertainty.
Why 811 Alone Is Often Insufficient for ALTA Surveys
A major misconception in the industry is that public 811 locates satisfy Table A Item 11(b).
In many cases, they do not.
The standards themselves acknowledge that:
“811 or other similar utility locate requests from surveyors may be ignored or result in an incomplete response.”
This is particularly true for:
- private utility systems,
- industrial campuses,
- hospitals,
- refineries,
- ports,
- universities,
- military facilities,
- airports,
- and large commercial developments.
Public utility owners generally only mark facilities they own.
That leaves major gaps involving:
- private electric,
- site lighting,
- irrigation,
- telecom,
- fiber,
- propane,
- chilled water,
- storm systems,
- abandoned lines,
- and owner-installed infrastructure.
This is precisely where private utility locating firms become indispensable.

Risk Reduction for Surveyors
One of the largest risks on ALTA surveys is omitted utility evidence.
Missed utility corridors can create:
- title disputes,
- design conflicts,
- easement disputes,
- construction delays,
- change orders,
- and professional liability exposure.
By partnering with utility locating specialists, surveyors can improve:
- defensibility,
- completeness,
- coordination,
- and client confidence.
The New Table A Item 20 Is Also Important
Another major 2026 addition is the expanded Table A Item 20.
This new section requires summarized tables identifying:
- potential encroachments,
- setback conflicts,
- access conflicts,
- and easement-related physical conditions.
Utility infrastructure frequently contributes to these conflicts.
Examples include:
- utility poles encroaching into setbacks,
- underground utilities outside easements,
- private utility crossings,
- undocumented access paths,
- or infrastructure occupying adjoining property.
The result is a stronger expectation that surveyors identify and communicate physical conflicts—not merely map geometry.
The Industry Is Moving Toward Integrated Survey + Utility Workflows
The 2026 ALTA standards reflect a broader industry shift:
Boundary surveying, utility locating, geospatial documentation, and infrastructure risk analysis are becoming increasingly interconnected.
Modern projects demand more than boundary retracement.
Clients now expect:
- utility awareness,
- subsurface risk visibility,
- infrastructure coordination,
- and defensible documentation.
Surveyors who integrate professional utility locating into their ALTA workflows will likely be better positioned to:
- reduce liability,
- improve deliverable quality,
- support civil engineering teams,
- and meet evolving client expectations.
Final Thoughts
The 2026 ALTA/NSPS standards do not transform surveyors into utility engineers or private locators.
What they do is elevate the importance of observable utility evidence, clearer documentation, and coordinated subsurface utility awareness.
For surveyors, the message is straightforward:
- Table A Item 11(b) deserves more serious attention.
- Utility evidence is now more explicitly embedded into ALTA expectations.
- Professional utility locating support is increasingly essential on complex sites.
As project sites become denser and infrastructure conflicts become more expensive, partnerships between land surveyors and utility locating firms will continue to grow in importance.
