What the ground in Omaha is like

The USDA soil survey rates mapped ground in Omaha for septic drain-field suitability across roughly 143 square miles. About 40% of the rated ground is classed "Not limited", meaning the soil has features that are very favorable for a conventional drain field.

In Omaha, the leading limit is slope: the ground falls steeply enough that a level trench line is hard to hold. A drain field has to sit across the grade without concentrating flow downhill; on steeper parcels that layout gets tighter. The survey flags that limit on about 44% of the rated ground here.

The limiting features the survey records most often here:

• Slope44.0%
• Slow water movement23.1%
• Flooding5.9%
• Depth to saturated zone5.6%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
