What the ground in Lexington is like

The USDA soil survey rates mapped ground in Lexington for septic drain-field suitability across roughly 19 square miles. About 50% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Lexington, 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 90% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement90.1%
• Slope34.3%
• Seepage, bottom layer17.6%
• Depth to saturated zone10.9%

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.
