What the ground in Las Cruces is like

The USDA soil survey rates mapped ground in Las Cruces for septic drain-field suitability across roughly 77 square miles. About 73% 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 Las Cruces, the leading limit is filtering capacity: the soil does not clean effluent thoroughly enough on its way through. A drain field is a treatment system as well as a disposal path; when the ground cannot filter well, pathogens and nutrients travel farther than the survey allows. The survey flags that limit on about 39% of the rated ground here.

The limiting features the survey records most often here:

• Filtering capacity38.8%
• Slope31.2%
• Slow water movement30.5%
• Depth to cemented pan16.3%

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.
