Private wells in Santa Cruz County
In 2015 about 26,214 of Santa Cruz County’s 274,146 residents (10%) got their drinking water from a private well, by the USGS estimate. That is the 33rd highest share of the 58 California counties in the USGS table, and the 21st highest number of private-well users.
As we read it, this rule covers the septic system, not the well.

Soils and septic systems here
USDA soil surveys rate 99% of Santa Cruz County’s rated land “very limited” for a conventional septic drain field, 0% “somewhat limited” and 0% “not limited”, the 3rd highest “very limited” share of 16 California counties with survey data. The most common limits: steep slopes on 87%; shallow bedrock on 72%; slow percolation (dense or clay soil) on 53%.
Where soils are limited, inspections more often find drain fields that sit in seasonally wet soil, and replacement systems are often mounds or other engineered designs. A county-wide rating, not a test of one lot: a site evaluation decides.
