What the ground in Boerne is like

The USDA soil survey rates mapped ground in Boerne for septic drain-field suitability across roughly 12 square miles. About 100% 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 Boerne, 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 72% of the rated ground here.

The limiting features the survey records most often here:

• Depth to bedrock71.6%
• Slow water movement59.3%
• Flooding14.5%
• Slope7.7%

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.
