What the ground in Louisville is like

The USDA soil survey rates mapped ground in Louisville for septic drain-field suitability across roughly 61 square miles. About 97% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.

In Louisville, 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 91% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement91.4%
• Depth to saturated zone19.2%
• Slope14.2%
• Depth to bedrock11.3%

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.
