Major concerns
Possible, but hard and costly. The growing season is about 136 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator. Water is easy here, with about 45 inches of rain a year and wells near 170 feet. The ground is steep, with slopes averaging about 39%. That raises the cost of a driveway, septic, and foundation.
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
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 $21,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 136 frost-free days, USDA zone 6b; last frost about May 23, first about October 7
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
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 across much of the county. Plan cleared ground around the house and fire-resistant materials.
U.S. Forest Service wildfire hazard map: Low to Very High here
Storms
Hurricanes and strong tornadoes are rare here.
NOAA: no hurricane-strength storm within 50 miles since 1975; no strong (EF2 or stronger) tornado within 25 miles since 1990
Terrain
Steep. A flat house site and a driveway route will drive the cost.
Slopes average about 39%, about 3,660 feet above sea level
Soil
Expect a costlier septic system, because the ground is steep. The county's soil test decides.
Silt loam, well 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 0.4 miles (OpenStreetMap)
