West Millard-Juab Area, Utah, Parts of Millard and Juab Counties
The most common soil here is Dera, on about 20% of the land: a gravelly sandy loam, gritty and crumbly. Amtoft and Goshute come next.
About 93% of the land drains well, and 7% stays wet for long stretches; groundwater comes within two feet of the surface under 7% of it.
USDA rates 87% of the land very limited for a standard septic drain field, and 38% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: bedrock lies within 40 inches under 32% of it.

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.
What This Means
Building & Foundations
About 38% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.
Septic Systems
About 87% 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.
