Major concerns
Possible, but hard and costly. Only about 15 inches of rain falls a year, so you will rely on a well (near 200 feet here) or hauled water. The growing season runs about 296 frost-free days, long enough for a spring and a fall garden. The U.S. Geological Survey maps strong earthquake shaking here, so build to the seismic code.
What the land says
Rain
Too dry to live on rain. Plan on a well, and on irrigating anything you grow.
About 15 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 200 feet deep; a well typically runs $11,000 to $24,000
Growing season
Long enough for a spring and a fall garden.
About 296 frost-free days, USDA zone 9b; last frost about February 11, first about December 1
Sun
Strong sun. A modest solar array covers a household.

Wildfire

NOAA: no hurricane-strength storm within 50 miles since 1975; no strong (EF2 or stronger) tornado within 25 miles since 1990
Earthquakes
Strong shaking is possible. Build to the seismic code and brace the water tank.

Terrain
Rolling ground. Look for a flat house site.
Slopes average about 14%, about 300 feet above sea level
Soil
Expect a costlier septic system, because rock or a hard layer sits about 16 inches down. The county's soil test decides.

Zoning

Rainwater
Collecting it is allowed.
Composting toilets
Allowed with a permit and an approved unit.
Water rights
A mix of two systems. Ask the state water office before you drill a well or dam a creek.
Drilled to about 200 feet, with pump and pressure tank

$10,000 to $20,000
Mound, sand filter, or treatment unit
