Service Areas

Arkansas splits into six natural divisions, and a barndominium in each one is a slightly different job.

The Ozarks (northwest and north). Eroded plateaus of limestone, dolostone, sandstone and chert, with fairly deep soils on the plateau tops and shallow soils on the hillsides around Fayetteville, Springdale, Rogers and Harrison. Limestone country brings sinkholes, and the state septic rules keep drain fields at least 100 feet from any sinkhole. Rock close to the surface changes footing and trenching costs.

The Ouachita Mountains (west-central). Tightly folded east-west ridges of sandstone and shale running from Oklahoma toward western Little Rock, past Mena and Mount Ida. Ridges have shallow soils and the wide valleys have deeper ones, so a valley pad and a ridge-top view lot are priced differently.

The Arkansas River Valley. Broad, rolling plains with scattered mountains between the Ozarks and the Ouachitas, from the Oklahoma line east to near Batesville, split by wide river bottomlands. Bottomland parcels need a flood-zone check before the pad elevation is set.

The West Gulf Coastal Plain (south). Rolling sandy hills and pine timber from the Ouachitas south to the Louisiana line, with blackland prairie soils in places and the expansive Porters Creek Clay belt near Hope and Arkadelphia. Slab design matters most here.

The Delta (east). The Mississippi Alluvial Plain covers the eastern third of the state and is extremely flat, with local relief of only a few feet. Drainage, pad height and clay pans under farm ground shape the site work.

Crowley's Ridge. A narrow ridge, more than 150 miles long, rising less than 200 feet above the Delta, with Jonesboro its largest city. Loess up to fifty feet thick at the south end drains well but can slide on steep cuts, so grading is kept gentle.

Across all six, average yearly precipitation runs about 45 to 55 inches, and a high Ozark mountaintop can average more than eight degrees cooler than the Louisiana line, which matters when sizing insulation and HVAC.
