Bay County, MI · off-grid fact sheet

Can you live off-grid in Bay County, Michigan?

84
of 100
Good with caveats

Yes, with two things to plan around. Wells are shallow here, near 150 feet, which keeps drilling costs down. Solar is weaker here, about 4.3 hours of full sun a day, so plan a bigger battery bank or a generator. Septic will likely cost more, because the soil stays wet for long stretches.

What the land says

Rain
Rain helps, but plan on a well for most of your water and on watering the garden in dry months.
About 32 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 150 feet deep; a well typically runs $7,000 to $17,000
Growing season
Enough for most vegetables. Start tomatoes and peppers indoors.
About 167 frost-free days, USDA zone 5b; last frost about May 1, first about October 16
Sun
Fair sun. Plan a larger array or a generator for winter.
About 4.3 hours of full sun a day, averaged over the year
Flood

Wildfire
Low wildfire risk.

Storms
Hurricanes and strong tornadoes are rare here.
NOAA: no hurricane-strength storm within 50 miles since 1975; about 0.6 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
Slopes average about 1%, about 630 feet above sea level
Soil
Expect a costlier septic system, because the soil stays wet for long stretches. The county's soil test decides.
Loam, 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 1 mile (OpenStreetMap)
