Possible, but water will be hard. Only about 16 inches of rain falls a year, so you will rely on a well (near 170 feet here) or hauled water. The ground is mostly flat and drains well, which keeps building simple. The growing season is only about 114 frost-free days, so plan on cold-hardy crops and a greenhouse.
What the land says
Rain
Too dry to live on rain. Plan on a well, and on irrigating anything you grow.
About 16 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 170 feet deep; a well typically runs $9,000 to $20,000
Growing season
Very short. A greenhouse makes the difference.
About 114 frost-free days, USDA zone 6a; last frost about June 3, first about September 20
Sun
Good sun. Size the array and battery bank for winter.
About 5.1 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
Wildfire risk is high in parts of the county. Check the risk for the parcel you want.
U.S. Forest Service wildfire hazard map: Very Low to High here

NOAA: no hurricane-strength storm within 50 miles since 1975; no strong (EF2 or stronger) tornado within 25 miles since 1990

USGS seismic hazard map: high
Terrain
Flat to gentle, easy to build on.
Slopes average about 5%, about 5,020 feet above sea level
Soil

Silt loam, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000

Zoning
We found no public zoning map for Oneida County, so call the county planning office with the parcel number to ask whether the land is zoned.

Collecting it is allowed.

Water belongs to whoever claimed it first. A new well or pond may need a state permit, and a creek may already be claimed.
