Texas Soil Drainage Rankings

Texas

How well does the soil drain across Texas? We ranked every USDA survey area by the percentage of land classified as "well drained." Areas at the top of the list have soils where water moves through at a healthy rate — favorable for building, septic, and gardening. Areas at the bottom have more waterlogged or slowly-draining soils that may require engineered solutions.

The best-drained survey area is Irion County, Texas at 100% well-drained soils. The most drainage-challenged is Calhoun County, Texas at 0%. With 49% poorly-drained soils, properties in Calhoun County, Texas should budget for drainage engineering, alternative septic designs, or raised-bed gardening.
