Significant challenges
Possible, but wildfire will be hard. The U.S. Forest Service rates wildfire risk high across much of the county, so plan cleared ground around the house. The sun is strong, about 5.8 hours of full sun a day, so a smaller solar array covers a household. Typical well depths here range from 60 feet to 300 feet, so get a local driller's quote.

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.
