Can you live off-grid in McIntosh County, Oklahoma?
91
of 100
Good with caveats
Yes, with two things to plan around. Water is easy here, with about 45 inches of rain a year and wells near 50 feet. NOAA counts about four strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan. Septic will likely cost more, because rock or a hard layer sits about 42 inches down.
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 45 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 50 feet deep; a well typically runs $3,000 to $8,000
Growing season
A full season for most vegetables.
About 227 frost-free days, USDA zone 7b; last frost about March 28, first about November 10
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.

Terrain

Slopes average about 5%, about 780 feet above sea level
Soil
