Nebraska Sandhills, Loess Plains & Eastern Till Margin
Dominant Soil Order: Mollisols / Entisols / Aridisols
Parent Material: Eolian Sand Dunes (Sandhills), Peorian Loess and Till-Derived Silt Loam in the East, Ogallala Gravel and Caliche below
Nebraska grades from the deep eolian sand of the Sandhills in the center-west to loess-capped till plains in the east, and the excavation story changes with it. The Sandhills counties (Cherry, Garden, Grant, Hooker, Thomas) are pure dune sand: digging is trivial but trench walls collapse immediately, groundwater sits within a few feet in the interdunal valleys, and septic systems are standard trenches with generous separation because the sand filters so well. The loess plains and the eastern counties (Lincoln, Omaha fringe) are silty loam over till and Ogallala gravel: diggable, with caliche and gravel hardpan in the western draws, and the state's modest shrink-swell (plains average under 3 percent) concentrated in the Republican River valley clays. Slope is minimal statewide (6 percent average) except along the Niobrara and the Panhandle breaks. Hydric soils concentrate in the Sandhills wetlands and the Rainwater Basin. Frost runs 36-42 inches. Rock is absent except in the Panhandle escarpments.
Geographic Footprint:Nebraska's counties (Omaha, Lincoln, Grand Island, North Platte) run from till-plain loess in the east to pure Sandhills dune sand in the center-west: easy digging, collapsing sand trenches, high water in the dunal valleys, and caliche in the western Panhandle. The 36-42 inch frost line shapes all utility work.

Area-specific FAQ
Do I need to call before digging in Saline County?
Yes. You should contact Nebraska 811 at least 2 working days before any digging so underground lines can be marked.
How deep do footings need to be in Nebraska?
In Nebraska, footings typically need to extend below the frost line, which is around 36 inches here. A local contractor will confirm the code requirement for your site.
