What the ground in Caldwell is like

The USDA soil survey rates mapped ground in Caldwell for septic drain-field suitability across roughly 4.3 square miles. About 96% 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 Caldwell, 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 100% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement100.0%
• Depth to saturated zone11.9%
• Flooding8.3%
• Depth to bedrock4.8%

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.
