- Seismic design category (ASCE 7-22): SDC C — moderate seismic risk, continuous-rebar-tie footings required
- Hurricane wind tier: No hurricane wind-design exposure
- Water table risk: Moderate — water table below frost line in most lots
- Sulfate exposure (ACI 318): S0 — no sulfate exposure, Type I/II cement adequate
- IECC climate zone: 3A-4A

How foundation pour costs vary in Arkansas
State-specific code or insurance rule: Arkansas Code §17-25-101 sets one of the lowest residential contracting thresholds at $2,000 — and Arkansas is unusual among Southern states in adopting the New Madrid Seismic Zone Special Inspection Program through Arkansas Code §12-30 requiring continuous-rebar-tie footings, minimum 3500 psi compressive strength, and special-inspector observation on every residential foundation pour in Crittenden, Greene, Mississippi, Poinsett, Cross, Lee, Phillips, St. Francis, Craighead, Lawrence, and Randolph counties — the most stringent foundation-specific seismic mandate in the South Central region.
