What the land says
Rain
Rain can supply much of a household's water with a large tank. A garden mostly waters itself in normal years.
About 58 inches a year (PRISM, 1991 to 2020 average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 120 feet deep; a well typically runs $5,000 to $11,000
Growing season
Long enough for a spring and a fall garden.
About 263 frost-free days, USDA zone 8b; last frost about March 5, first about November 23
Sun
Good sun. Size the array and battery bank for winter.
About 5.2 hours of full sun a day, averaged over the year

Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
