Pierce County, North Dakota
The most common soil here is Heimdal, on about 13% of the land: a loam, a balanced mix that crumbles in your hand. Emrick and Gardena come next.
About 38% of the land drains well, and 27% stays wet for long stretches; groundwater comes within two feet of the surface under 23% of it.
USDA rates 53% of the land very limited for a standard septic drain field, and 28% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

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 28% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.
Septic Systems
About 53% 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
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.
