Gulf Coastal Prairie Clays & Flatwoods

Dominant Soil Order: Vertisols / Alfisols / Entisols
Parent Material: Quaternary Gulf Coastal Plain Clay, Silt, and Sand, with Fluvial and Marine Deposits

The Gulf Coastal Prairie is flat, wet, and clay-heavy. SSURGO mapping shows Lake Charles and Katy, Victoria, and Aransas soils near the coast, with Vertisols, Alfisols, and Entisols. Water tables are high and drainage is poor. Shrink-swell clays are severe, so slabs and pipe move as the soil wets and dries. Wet clay is weak and sticky, and equipment sinks in it. Deep trenches fill with water in the coastal flats. The lowest ground stays saturated after heavy rain, and water stands on the surface for days. Clay pads lose their workable window when rain falls, and wet weather can last for weeks. Coastal flats include saltwater wetlands along the shore, where the surface stays soft and wet. Quaternary clay, silt, and sand deposits form the parent material.

Area-specific FAQ

Do I need to call before digging in Fort Bend County?
