What are foundation conditions like in Guthrie, Oklahoma?

Reviewed by Preston · Updated 2026-11-12

In short: Only about 4% of Guthrie is mapped in high shrink-swell soil; 40% rates low ¹. The soil survey also maps bedrock within 40 inches under about 47% and occasional or frequent flooding on about 15% ¹. Which of these a house sits on decides whether clay swell, water, rock or soft ground is the thing to watch.

What does the soil survey show for Guthrie?

Guthrie covers about 18 square miles ² and had 10,749 people in the 2020 Census ².

• Coyle, about 16% of the area ¹: Moderately deep, well drained soils that formed in material weathered from sandstone of Permian age ³.
• Zaneis, about 10% of the area ¹: Deep, well drained soils that formed in material weathered from interbedded sandstone and shale of Permian age ⁴.
• Ashport, about 8% of the area ¹: Very deep, well drained soils that formed in loamy alluvium of Holocene age ⁵.
• Stephenville, about 7% of the area ¹: Moderately deep, well drained, soils formed in material weathered from sandstone of Permian age ⁶.
• Ironmound, about 7% of the area ¹: Shallow, well drained soils that formed in material weathered from sandstone, or sandstone interbedded with siltstone or shale, of Permian age ⁷.
• Urban land, about 14%, is ground the survey maps as covered by buildings and pavement rather than classifying its soil ¹.

What does this mean for houses in Guthrie?

Shallow rock. Where bedrock is close to the surface, lots are often cut into rock on one side and built up with fill on the other, so fill settlement and slope creep matter more than clay swell, and piers can stop at very different depths across one house. See depth to rock from borings.

Flood-prone soils. Floodplain soils are layered stream deposits: softer, wetter and more variable than upland soils, and they flood. See soft soil consolidation and Quaternary alluvium and terraces.

How were these numbers measured?

We overlaid the city limits from the Census Bureau ² on the USDA soil survey's map units ¹ and added up the area of each soil. Where a map unit is a mix of soils, its area was split by the percentages the survey lists for its major soils, so shares leave out minor inclusions and do not add to 100%. Shrink-swell is rated by the linear extensibility of a soil's most expansive layer, the survey's measure of how much it changes length between wet and dry (6% or more is high). Water table, bedrock and flooding come from the survey's map-unit summaries: the shallowest water table in any month, the shallowest bedrock, and the most common flooding frequency. Bedrock here includes soft, weathered sandstone and shale that a pier can push through, so it is not the depth where piers stop. These are mapped averages, not a test of any one lot; fill, grading and the soil actually under a house can differ, which is why a site visit or soil boring still decides a repair.
