What the ground in Silver City is like

The USDA soil survey rates mapped ground in Silver City for septic drain-field suitability across roughly 10 square miles. About 100% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Silver City, 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 70% of the rated ground here.

The limiting features the survey records most often here:

• Depth to bedrock70.3%
• Slope69.1%
• Slow water movement48.3%
• Large stones5.0%

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.
