This sounds very much like my parents’ house, with the exception of the basement, which the height of the water table in winter prohibits. They have their house on a high spot and on a high foundation, but they’ve had water two stairsteps below their ground floor at least three times in the last 50 years. (The spread of the local land would require a LOT of water to get higher than that.) They have only relatives for close neighbors, but I think they know a hundred or so fellow parishioners within a five-mile radius well enough to ask for meaningful emergency help, and as most of them are other logging and farm families with a smattering of nurses, they are a useful group to be on good-neighbor terms with.
Most of the locals or their families moved into that area some time between 1880 and 1920. (We joke that the kids have to go off to college to find a spouse that’s not a relative!

) That isn’t the case for most people. The average American moves every
7 years. This is more like the area I live in now. But we know our closest neighbors well enough to be willing to give at least 2-3 of them keys to our house and codes to our alarm, should disaster strike while we’re away from home. We also borrow back and forth, whether for dinner party or ice storm emergencies. Based on the last few ice storms (we usually have at least one power outage every winter), the neighbors are pretty well set, although it would be tighter if an earthquake hit during the winter and wiped out our natural gas.
Although wood stoves and fireplaces are popular, the local population density is such that they aren’t encouraged as a primary heat source, for the sake of air quality. This makes your basement with optional wood heat a great idea. Someone in our area could use that idea to have a wood-fired heat source that carries a lot of wallop and combine it with a cleaner alternative like gas that they could use most of the time.
