What are foundation conditions like in Sand Springs, Oklahoma?

Reviewed by Preston · Updated 2026-11-11

In short: Sand Springs has the smallest share of high shrink-swell soil of the Tulsa-area cities compared, about 19% ¹, and the largest share of rock outcrop. Hillsides with shallow sandstone and clay over shale make slope, fill and drainage the main foundation concerns, while the Arkansas River side has deep, soft ground.

How much of Sand Springs has expansive soil?

Sand Springs covers about 21 square miles ² across four county soil surveys (Tulsa, Osage, Pawnee and Creek) ¹.

Which Sand Springs soils matter most for houses?

• Niotaze, about 14% of the city, is a soil of wooded hillsides with a stony sandy surface over a dense smectitic clay subsoil and shale 20 to 40 inches down; it is somewhat poorly drained ³.
• Bigheart is shallow and well drained to somewhat excessively drained, formed from Pennsylvanian sandstone on crests and upper side slopes, with slopes of 1 to 45 percent ⁴.
• Rock outcrop covers about 8% of the city ¹.
• Newtonia is very deep and well drained, formed in loess and residuum ⁵; Kamie is very deep and well drained on high terraces formed in loamy alluvium ⁶; Choska is on low terraces of floodplains ⁷.

What does hillside ground mean for foundations?

Hillside lots on shallow rock are often built up with fill. Problems there tend to come from fill settlement, slope creep and runoff rather than clay swell.

What is under the river side of Sand Springs?

Borings at the Sand Springs site for the Arkansas River corridor projects found 18 to 35 feet of soil over rock in the river banks, versus about 4 to 10 feet within the channel, and the river shale averaged 565 psi over six tests ⁸. See depth to rock from borings.

How were these numbers measured?

We overlaid the city's current 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 the shares above leave out minor inclusions and do not add to 100%. A soil counts as high, moderate or low shrink-swell by the linear extensibility of its most expansive layer, the survey's measure of how much a soil changes length between wet and dry (6% or more is rated 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 for the whole city, 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.
