What the ground in Crossville is like

The USDA soil survey rates mapped ground in Crossville for septic drain-field suitability across roughly 21 square miles. About 94% 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 Crossville, the leading limit is depth to bedrock: rock sits close enough to the surface that there is not enough soil column above it for a conventional field to sit in. Effluent needs that depth to disperse; when bedrock comes up, the workable layer runs out. The survey flags that limit on about 89% of the rated ground here.

The limiting features the survey records most often here:

• Depth to bedrock89.0%
• Slope76.5%
• Seepage, bottom layer76.2%
• Slow water movement24.4%

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.
