Civil Engineer vs. Land Surveyor in Georgia: Which One Do You Actually Need?
Property owners and developers in Georgia routinely confuse civil engineers and land surveyors — and it costs them. Hiring the wrong professional first means redoing work, delaying permits, and sometimes losing the deal entirely. This guide explains in plain language what each profession does, what each is legally allowed to do, when you need one or the other, and when you need both.
Key Takeaways
Both professions are regulated in Georgia by the Georgia Board of Professional Engineers and Land Surveyors (PELS).
- A Professional Land Surveyor (PLS) measures, marks, and legally documents the boundaries, elevations, and features of land. Their work is largely backward-looking — it tells you what is there.
- A Professional Engineer (PE) — specifically a civil engineer — designs improvements to the land: grading, drainage, stormwater, roads, utilities. Their work is forward-looking — it tells you what should be built.
- Boundary surveys, ALTA surveys, plats, and elevation certificates require a PLS seal.
- Land disturbance plans, stormwater designs, road and drainage plans, and most permit drawings require a PE seal.
- Most land development projects need both, in this order: surveyor first, then civil engineer.
What a Georgia Land Surveyor (PLS) Does
A Professional Land Surveyor is legally responsible for the precise measurement and legal description of land. Georgia’s licensure law requires significant education and supervised experience before a PLS can practice. Common surveying products include:
- Boundary survey — establishes the exact perimeter of a property based on deeds, plats, and field measurements
- Topographic survey — adds elevation contours and existing site features (trees, buildings, utilities)
- ALTA/NSPS Land Title Survey — the gold-standard commercial survey required by most lenders and title insurers
- Plat of subdivision — the legal document that creates new lots, recorded with the county
- Elevation Certificate — required for FEMA flood insurance rating
- Construction staking — laying out building corners, road centerlines, and utilities on the ground
- As-built survey — verifies after construction that improvements match the approved plans
What a Georgia Civil Engineer (PE) Does
A civil engineer designs the improvements on the land — and stamps the plans that the government will use to approve construction. In Georgia, common civil engineering deliverables include:
- Land Disturbance Plans (LDP) and Erosion Control Plans
- Stormwater management design (detention ponds, water quality BMPs, hydrology calculations)
- Grading and drainage plans
- Road, driveway, and parking lot design
- Water, sanitary sewer, and septic system design
- Feasibility reports and concept site plans
- Construction management and inspection oversight

When You Need Both — And the Right Order
Most land development projects need both professionals. The right sequence is:
- Hire a land surveyor first. Without an accurate boundary and topographic survey, the civil engineer has nothing reliable to design from. Designing on a guess is the fastest way to redo a set of plans.
- Hire a civil engineer next. The engineer designs the project using the surveyor’s base information.
- Engage the surveyor again at construction. For construction staking, as-built verification, and (if the project creates new lots) the final plat for recording.
Common Real-World Scenarios
“I want to build a fence between me and my neighbor.”
Hire a land surveyor only. You need a boundary survey or a property pin location, not a civil engineer.
“I want to build a backyard shed on my own lot.”
In most jurisdictions, a recent boundary survey or accurate site sketch is sufficient. A civil engineer is not required unless the lot has stormwater or drainage complications.
“I want to subdivide my 5 acres into 3 lots.”
You need both. Surveyor for the boundary, topo, and final plat. Civil engineer for any required infrastructure design, stormwater, and the land disturbance permit if the disturbed area exceeds one acre.
“I want to build a medical office on a vacant commercial parcel.”
You need both, plus an architect and likely a geotechnical engineer. Surveyor produces the boundary and topographic survey; civil engineer produces the site engineering, stormwater design, and permit drawings; architect designs the building; geotech evaluates soil bearing.
“I want to refinance and my lender asked for an ALTA survey.”
Hire a land surveyor only. An ALTA is a surveyor product.
“My property keeps flooding.”
Hire a civil engineer first. The engineer will evaluate the drainage problem, may request a topographic survey from a PLS as part of the work, and will design a fix.
“I want a FEMA Letter of Map Amendment (LOMA) to remove my property from the floodplain.”
You need both. Surveyor produces the elevation certificate; civil engineer prepares the hydrologic and hydraulic analysis if a flood study is required.
What About Architects, Geotech, Landscape Architects, and Environmental Consultants?
On a complex project, the full team often includes:
- Architect — building design and code compliance
- Structural engineer — building structural systems
- Geotechnical engineer — soil bearing, foundation recommendations
- Landscape architect — planting and hardscape design, sometimes stormwater BMPs
- Environmental consultant — Phase I/II environmental site assessments, wetlands delineation
- Traffic engineer — traffic impact studies and signal warrants
A good civil engineer functions as the technical quarterback who coordinates these disciplines and packages the permit submittals.
Frequently Asked Questions
Can a civil engineer perform a boundary survey?
No. Boundary determination is the exclusive practice of a Professional Land Surveyor in Georgia. A civil engineer cannot legally seal a boundary survey.
Can a land surveyor design a stormwater detention pond?
No. Stormwater design, hydrology calculations, and stamped permit drawings are the practice of engineering and require a PE seal.
Who prepares the final plat for a subdivision?
A Professional Land Surveyor prepares and seals the final plat. The civil engineer’s plans are the basis for the design, but the recorded plat is a surveyor product.
Can one firm provide both services?
Yes. Many firms employ both PEs and PLSs and provide a single integrated team. Smaller firms often partner with a trusted surveyor on each project.
Which one do I hire first?
Almost always the surveyor — unless you are still in pre-purchase due diligence, in which case the civil engineer’s feasibility analysis can come first and the survey can wait until you are under contract.
