Local conditions

Survey conditions in Horry County

Horry County is one of the fastest-growing coastal counties in the Southeast, with active residential subdivision, commercial corridor development along US-501 and US-17, and ongoing infrastructure work tied to the Grand Strand's tourism economy. Low coastal plain elevations, widespread wetland systems, and FEMA flood zone complexity mean that a survey error caught late costs far more than the survey itself. Before a single grade stake is driven or a footing form is set, the legal boundary, existing topography, and design geometry all have to be reconciled on the ground with precision. Our field crews handle boundary delineation, topographic data collection, and construction staking for projects ranging from single-lot residential to large planned developments. Work in Horry County is dispatched through our Raleigh, NC regional hub and scheduled on a project-by-project basis, giving contractors and design teams a defined scope and realistic turnaround to plan around.

Horry County's coastal plain soils are often sandy, low-lying, and subject to seasonal high water tables, which can complicate benchmark establishment and require crews to account for soft or saturated ground conditions when setting hubs and stakes. Flood zone designations across much of the county make accurate elevation data — tied to current NAVD 88 benchmarks — a practical necessity for permitting and site design, not an optional add-on.

FAQ · Horry County

How does FEMA flood zone mapping affect what my survey needs to include in Horry County?

Much of Horry County falls within FEMA Special Flood Hazard Areas, so topographic surveys here typically need to establish finished floor and site elevations tied to NAVD 88 to support Elevation Certificate preparation and local floodplain permitting. If your project triggers an Elevation Certificate, coordinate with your engineer early so the survey scope captures the data points FEMA Form 086-0-33 requires.

What datum and vertical control should my survey reference for a project near the Grand Strand?

Projects in coastal Horry County should reference NAVD 88 for vertical control, consistent with FEMA flood mapping and South Carolina DHEC coastal permitting requirements. Our crews tie elevations to established NGS benchmarks. Using an arbitrary or assumed datum is workable for isolated grading work but creates reconciliation problems if the survey must interface with floodplain, utility, or public infrastructure data.

Horry County has a lot of wetland buffers and setbacks — can your survey crew locate and flag those for my site plan?

We can locate and depict delineated wetland flags set by a qualified wetland delineator on a topographic or boundary survey, integrating them with property lines and existing features. We do not perform the wetland delineation itself — that requires a separate environmental consultant — but once flags are in place, incorporating them into the survey base map is a straightforward part of the scope.
