What the ground in Little Rock is like

The USDA soil survey rates mapped ground in Little Rock for septic drain-field suitability across roughly 121 square miles. About 91% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Little Rock, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 85% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement84.6%
• Depth to bedrock52.5%
• Depth to saturated zone36.1%
• Slope26.3%

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.
