What the ground in North Highlands is like

The USDA soil survey rates mapped ground in North Highlands for septic drain-field suitability across roughly 8.8 square miles. About 60% of the rated ground is classed "Not limited", the survey records few restrictions for a conventional drain field across most of that ground.

In North Highlands, 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 40% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement39.8%
• Depth to cemented pan36.4%
• Depth to bedrock24.3%
• Flooding2.8%

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.
