Can you live off-grid in Anderson County, Kansas?

Good with caveats

Yes, with one thing to plan around. Water is easy here, with about 40 inches of rain a year and wells near 30 feet. Septic will likely cost more, because the soil stays wet for long stretches.

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 40 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 30 feet deep; a well typically runs $3,000 to $7,000
Growing season
A full season for most vegetables.
About 193 frost-free days, USDA zone 6b; last frost about April 13, first about October 24
Sun
Good sun. Size the array and battery bank for winter.
About 5.2 hours of full sun a day, averaged over the year
Flood
Flood zones run along creeks and rivers here. Look up the parcel on FEMA's flood map.

Wildfire
Low wildfire risk.
U.S. Forest Service wildfire hazard map: Very Low to Low here
Storms
Hurricanes and strong tornadoes are rare here.
NOAA: no hurricane-strength storm within 50 miles since 1975; about 1 strong (EF2 or stronger) tornado a decade within 25 miles
Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
Slopes average about 2%, about 1,030 feet above sea level
Soil
Expect a costlier septic system, because the soil stays wet for long stretches. The county's soil test decides.
Silty clay loam, somewhat poorly drained (USDA soil survey). A mound, sand filter, or treatment unit typically runs $10,000 to $20,000
Road
Paved roads are close by.
Nearest paved road usually within about 0.5 miles (OpenStreetMap)
