What the Ground Looks Like in James Island
Every one of the 68 points we sampled on James Island landed on natural soil. None fell on open water.
At 12 points, the shallowest yearly water table is at the surface, and 24 are within 30 centimeters. Thirteen are poorly or very poorly drained. Twelve carry a frequent or very frequent flood rating.
Shrink-swell is low at 67 points and moderate at one. The survey points to water and flooding, not swelling clay. Use the Web Soil Survey to see your own lot.
NOAA's tide gauge in Charleston Harbor shows sea level rising about 1.4 inches every ten years. The gauge is in the harbor, not on the island.
Water control is covered on our drainage and water control page.

Foundation Questions in James Island, SC
Who handles building permits on James Island now?
The town's page says new permits and inspections have gone through the Town since May 1, 2026, with SAFEbuilt. Projects already in progress stay with Charleston County. Ask Town Hall if you are unsure.
Are old James Island homes more likely to need foundation work?
Age alone does not decide it. About 78 in 100 homes here were built before 1990, and the soil survey shows wet, flood-rated ground at many points. An inspection shows what applies to your house.
How does flood-prone ground affect a foundation?
Water can soften the soil under a footing and reach a crawl space. Twelve sampled points carry a frequent or very frequent flood rating. An inspection shows how your lot behaves.
