Skip to 2 contractorsSoil Regime ProfileEPA Ecoregion 39, 73, 74, 35 (Ozark Highlands, Mississippi Alluvial Plain, Arkansas Valley, South Central Plains)
Arkansas Ozark Highlands, Delta Alluvium & West Gulf Plains
Dominant Soil Order: Ultisols / Vertisols / Inceptisols / Alfisols
Parent Material: Ozark Cherty Limestone Residuum; Mississippi Alluvial Clay and Silt; West Gulf Coastal Plain Sand and Clay
Arkansas stacks three regimes vertically down the state. The Ozark Highlands (Fayetteville, Harrison, Mountain Home) are cherty limestone karst: thin stony soils over Ordovician-Mississippian carbonate, slopes of 30-70 percent, sinkholes and losing streams that make septic and stormwater design site-specific, and the Boston Mountains' sandstone caprock. The Arkansas River Valley and Ouachitas add sandstone-shale ridges and the state's modest rock work. The Delta (the east third, Memphis to Louisiana) is Mississippi alluvium: deep silty clay and clay, hydric soils on 40-60 percent of land, water tables within inches in spring, shrink-swell smectite clays, and rice-country drainage infrastructure that shapes every utility job. The West Gulf Coastal Plain south (Texarkana, El Dorado) is the easy half: sandy loam over Tertiary sediments, low slope, low shrink-swell, conventional septic systems standard. Frost is negligible; humid heat and storm loads drive drainage and erosion control.
Geographic Footprint:Arkansas's counties (Little Rock, Fayetteville, Fort Smith, Jonesboro) run from Ozark karst-and-slope through Delta gumbo to sandy Gulf plains: karst and rock in the northwest, seasonal wet clay in the east, easy sand in the south. Water management shapes the trade statewide.

Area-specific FAQ
Do I need to call before digging in Fulton County?
Yes. You should contact Arkansas 811 at least 2 working days before any digging so underground lines can be marked.
How deep do footings need to be in Arkansas?
In Arkansas, footings typically need to extend below the frost line, which is around 12 inches here. A local contractor will confirm the code requirement for your site.
