Leflore County, Mississippi
The most common soil here is Alligator, on about 35% of the land: a clay, sticky when wet and rock-hard when dry. Tensas and Dubbs come next.
About 16% of the land drains well, and 74% stays wet for long stretches; groundwater comes within two feet of the surface under 51% of it.
USDA rates 93% 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: 19% 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.
What This Means
Building & Foundations
About 93% of soils are rated "very limited" for dwellings with basements. Specific challenges include poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.
Septic Systems
About 93% 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.
