What the ground in Santa Clarita is like

The USDA soil survey rates mapped ground in Santa Clarita for septic drain-field suitability across roughly 74 square miles. About 89% 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 Clarita, 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 71% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement71.1%
• Slope62.3%
• Depth to bedrock47.3%
• Seepage, bottom layer27.1%

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.
