Significant challenges
Possible, but hurricanes will be hard. NOAA counts four hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages. Rain is plentiful, about 56 inches a year. The U.S. Forest Service rates wildfire risk high across much of the county, so plan cleared ground around the house.

Terrain
