What the ground in Lincoln is like

The USDA soil survey rates mapped ground in Lincoln for septic drain-field suitability across roughly 6.4 square miles. About 94% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Lincoln, 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 99% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement99.4%
• Depth to saturated zone63.6%
• Seepage, bottom layer34.0%
• Ponding20.5%
