Can you live off-grid in New Madrid County, Missouri?
87
of 100
Good with caveats
Yes, with two things to plan around. Water is easy here, with about 51 inches of rain a year and wells near 70 feet. The U.S. Geological Survey maps strong earthquake shaking here, so build to the seismic code. NOAA counts about four strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan.
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 51 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 70 feet deep; a well typically runs $4,000 to $10,000
Growing season
A full season for most vegetables.
About 216 frost-free days, USDA zone 7b; last frost about March 31, first about November 3
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 are rare here. Still, look up the parcel on FEMA's flood map.
FEMA maps no flood zones nearby
Wildfire
Low wildfire risk.
U.S. Forest Service wildfire hazard map: Very Low here
Storms
Strong tornadoes are common. A storm shelter belongs in the plan.
NOAA: no hurricane-strength storm within 50 miles since 1975; about 4 strong (EF2 or stronger) tornadoes a decade within 25 miles
Earthquakes
Strong shaking is possible. Build to the seismic code and brace the water tank.
USGS seismic hazard map: very high
Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
Slopes average about 0%, about 280 feet above sea level
Soil
Expect a costlier septic system, because the soil stays wet for long stretches. The county's soil test decides.

Road
Paved roads are close by.
Nearest paved road usually within about 0.5 miles (OpenStreetMap)
