Coastal Plain sandy loam and clay with Elizabeth River and Chesapeake Bay tidal influence creating very high water tables. Naval Shipyard area has industrial fill soils. Low-lying areas have organic marsh soils with poor percolation and flood exposure.
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.
The City of Portsmouth is a Hampton Roads urban locality with Norfolk Naval Shipyard and extensive Hampton Roads Sanitation District sewer coverage. Very few properties require septic systems, but older waterfront neighborhoods may have legacy private infrastructure.
