Soil & Terrain Characteristics
Coastal Plain sandy loam and clay soils with moderate seasonal water tables influenced by College Creek and Queens Creek. Colonial Williamsburg historic area has centuries-old modified soils. College of William & Mary campus has graded and filled terrain.
The Coastal Plain features flat terrain with naturally high water tables that create challenges for conventional septic systems. Many properties require advanced treatment systems, mound systems, or other alternatives designed to function where groundwater is close to the surface. Seasonal flooding and storm surge can also affect system performance in low-lying areas.
County-Specific Considerations
The City of Williamsburg is home to Colonial Williamsburg and the College of William & Mary. James City County Service Authority and Hampton Roads Sanitation District provide sewer to most of the city. Tourism infrastructure and historic preservation create unique land use considerations. As a Chesapeake Bay Preservation Act locality, mandatory pump-out every 5 years is required.
