Soil survey area

Currituck County, North Carolina

Survey Area NC053• North Carolina
The short version

The most common soil here is Kill Devil, on about 8% of the land. Roanoke and Pine Island come next.

About 6% of the land drains well, and 40% stays wet for long stretches; groundwater comes within two feet of the surface under 68% of it.

USDA rates 48% of the land very limited for a standard septic drain field, and 44% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 39% of the land floods occasionally or more.

Soil Orders in This Area

The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.

Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.
Ultisols
Strongly weathered clay soils of the Southeast. Acidic and naturally low in nutrients. Clay subsoil can slow drainage.
Histosols
Organic peat and muck soils formed in wetlands. Very poor for building (compressible) and septic. Often in regulated wetlands.

What This Means

Building & Foundations

About 44% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 48% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.

Gardening & Agriculture

Drainage is generally favorable for gardening. Adding compost and mulch will improve fertility and water retention. Test your soil's pH before planting — most vegetables prefer 6.0-7.0.
