Engineering & Land Surveying in St. George, Utah
Engineering and land surveying in St. George — boundary surveys, soils reports and site work for building in southern Utah.
Know where your boundary actually is
Surveying is one of those services people skip and then wish they had not. A boundary survey establishes where your property lines actually run, as against where a fence, a wall or long-standing assumption suggests.
It matters most in three situations: before building a fence or wall, before any construction near a line, and when buying land — particularly rural or larger parcels, where historic descriptions can be imprecise and long-standing occupation may not match the record.
The cost of a survey is small against the cost of moving a wall built in the wrong place, or of a dispute with a neighbor that becomes a legal matter.
Site conditions in this region
Geotechnical and soils reports determine what foundation a site requires. Conditions vary across Washington County, and some areas present expansive or otherwise problematic soils that require engineered foundations. On any significant build this is not optional, and it is far cheaper to know before designing than to discover during excavation.
Drainage and grading deserve particular attention here. The pattern of infrequent but intense storms means a site can look benign for years and then take a great deal of water quickly. Grading that moves water away from structures, and drainage designed for a burst rather than for average rainfall, is what prevents the damage.
Topographic surveys inform design on sloping lots, which many here are.
ALTA/NSPS surveys are the detailed standard commonly required for commercial transactions and lending.
Practical points
- Ask what type of survey you actually need — they differ substantially in scope and cost, and buying more than the situation requires is a common waste.
- Ask about turnaround, which can affect a transaction timeline.
- Ask whether corners will be physically marked and whether a recorded plat is produced.
- Check licensure. Utah licenses professional engineers and land surveyors through the Division of Professional Licensing, and status can be checked free in Utah's license verification tool.

Frequently asked questions
When do I need a boundary survey?
Before building a fence or wall, before construction anywhere near a property line, and when buying land — particularly rural or larger parcels where historic descriptions can be imprecise and where long-standing occupation may not match the recorded boundary. Existing fences are frequently not on the line. The cost of a survey is modest against the cost of relocating a wall built in the wrong place or resolving a boundary dispute with a neighbor after the fact.
Do I need a soils report to build here?
For any significant construction, generally yes, and it is far cheaper to have before designing than to discover during excavation. Soil conditions vary across Washington County, and some areas present expansive or otherwise difficult soils that require engineered foundations. The report determines what the foundation needs to be, which is a design input rather than a formality. Your designer, builder or the local building department can tell you what is required for your specific site.
Why does drainage matter in a place with so little rain?
Because of how the rain arrives. Annual precipitation here is well under ten inches, but it comes in intense bursts rather than spread evenly, so a site can appear entirely benign for years and then receive a great deal of water in a single afternoon. Grading that directs water away from structures and drainage designed for a heavy burst rather than for average rainfall is what prevents damage, and it is a design decision rather than something to address afterwards.
