What the ground in Cathedral City is like

The USDA soil survey rates mapped ground in Cathedral City for septic drain-field suitability across roughly 22 square miles. About 95% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Cathedral City, 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 86% of the rated ground here.

The limiting features the survey records most often here:

• Filtering capacity86.1%
• Slope23.7%
• Depth to bedrock8.3%
• Seepage, bottom layer4.5%

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.
