Soil survey area

Douglas County, Nebraska

Survey Area NE055• Nebraska
The short version

The most common soil here is Contrary, on about 10% of the land: a silt loam, smooth, like flour. Udarents and Udorthents come next.

About 34% of the land drains well, and 19% stays wet for long stretches; groundwater comes within two feet of the surface under 4% of it.

USDA rates 58% of the land very limited for a standard septic drain field, and 31% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 25% 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.

Mollisols
Fertile grassland soils with thick, dark topsoil. Among the best for agriculture, building, and gardening.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.
Inceptisols
Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.

What This Means

Building & Foundations

About 31% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 58% of soils are rated "very limited" for septic absorption fields. Despite good drainage overall, limitations may stem from shallow bedrock, steep slopes, or seasonal conditions. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.

Gardening & Agriculture

Well-drained soils on sloped terrain — good for most plants but watch for erosion. Terracing, contour planting, and mulching help retain moisture and topsoil. Drip irrigation is more effective than sprinklers on slopes.
