What the ground in Santa Cruz is like

The USDA soil survey rates mapped ground in Santa Cruz for septic drain-field suitability across roughly 13 square miles. About 98% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Santa Cruz, 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 85% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement85.3%
• Slope54.3%
• Depth to bedrock26.2%
• Seepage, bottom layer7.0%

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.
