Can you live off-grid in McCurtain County, Oklahoma?
85
of 100
Good with caveats
Yes, with two things to plan around. Water is easy here, with about 53 inches of rain a year and wells near 60 feet. Flood zones cover parts of the county, so look up any parcel on FEMA's flood map before you offer. The U.S. Forest Service rates wildfire risk high across much of the county, so plan cleared ground around the house.
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 53 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 60 feet deep; a well typically runs $4,000 to $9,000
Growing season
A full season for most vegetables.
About 227 frost-free days, USDA zone 8a; last frost about March 28, first about November 11
Sun
Good sun. Size the array and battery bank for winter.
About 5.0 hours of full sun a day, averaged over the year
Flood
Flood zones cover parts of the county. Look up any parcel on FEMA's flood map before you offer.
