Crawford County, Kansas
The most common soil here is Parsons, on about 33% of the land: a silt loam, smooth, like flour. Dennis and Zaar come next.
About 11% of the land drains well, and 74% stays wet for long stretches; groundwater comes within two feet of the surface under 60% of it.
USDA rates 99% of the land very limited for a standard septic drain field, and 93% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: 15% of the land floods occasionally or more, and bedrock lies within 40 inches under 15% 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 93% of soils are rated "very limited" for dwellings with basements. Specific challenges include steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.
Septic Systems
About 99% of soils are rated "very limited" for septic absorption fields. Poorly drained soils can't absorb septic effluent effectively. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.
Gardening & Agriculture
Many soils hold water for extended periods. Raised beds are highly recommended to improve drainage for vegetables. Well-adapted native plants and water-loving species will do best in natural conditions.
