Mount Pleasant is one of the fastest-growing communities in the Lowcountry, and the sitework here reflects that. New residential communities are going in along the highway and toward the northern sections of town, while established neighborhoods closer to the marsh and the older streets handle additions, outbuildings, and site improvements. In both settings, the coastal conditions — high water table, sandy soils, marsh proximity — shape how the earthwork has to be done.
On new residential lots, sitework is site preparation, finish grading, pad compaction, and stormwater infrastructure. The pad has to be compacted so the foundation doesn't settle in sandy coastal soil, and the grading has to shed water away from the structure and off the lot. Because so many lots are near marsh or tidal creek, the stormwater tie-ins have to be installed with the outfall in mind — a drainage system that discharges into a tidal creek only works when the tide is out, and the grading and infrastructure have to account for that.
In the established sections of Mount Pleasant, sitework is more surgical. An addition or outbuilding on a lot with mature trees and an existing drainage pattern means careful clearing, grading that protects what's already working, and drainage work that doesn't push water toward the marsh or a neighbor. The high water table means even shallow excavation can hit water, and the work has to be sequenced so an open cut doesn't fill with groundwater before it's finished.
Commercial sitework along Mount Pleasant's growing corridors brings grading for parking and access, stormwater inlets for concentrated runoff, and utility excavation. The same coastal constraints apply at a larger scale: the grading has to handle runoff to tidal outfalls, the stormwater structures have to be built for the traffic they'll see, and the utility trenching has to account for sandy soils that slough and a water table that's never far below the surface.
Whether the project is a new home in a growing community or an improvement on an established Mount Pleasant lot, the sitework has to respect the coastal conditions from the first cut. We walk the property, look at the soils and the outfall, and give you a clear estimate of what the work involves and what order it should happen in. Free estimates, honest recommendations.

The high water table on Mount Pleasant lots changes how sitework has to be sequenced. A pad cut too far below grade can sit in groundwater before it is compacted, and an open utility trench can fill with water before the pipe is laid. We keep cuts above the water table where the design allows, dewater where it doesn't, and close cuts fast so the wet ground doesn't have time to become a problem. On coastal lots, that also means staging material so it doesn't sink into soft ground and protecting the marsh and wetland buffers that border so many properties. The sitework has to work with the water table, not against it — and leave the coastal environment around the lot intact.
