I am lucky enough to live in the country. small farm, I am surroundeed by much larger farms. I agree this could never be done in city.
when we need room, my brother drops off a dozer or excavator and we just push out more trees.
When we need more storage, we dig another crease in the hill and bury another conex from fort bragg surplus
You are absolutly right about the water, In litterally all clay soils you must "hit water veins" I am again lucky enough to live in "sandland"( sandhills of NC.) as long as the water table is good the shallow well will never run out, and every drop is treated with 40 feet of sand filter, lol.Can be pumped out into barrels and chemically treated if need rises.
If it fails I still have 2 deep wells I could acess water from, one that I use for the plant nursery when the ponds start dropping too far, The other well its got so much iron in it I would probably treat water from the pond first LOL.
Depending on exactly what happens I do have have to worry about loosing the catfish, I have in the past had large dieoffs from pumping too much water to nursery, and the temp of water in ponds getting too high, then the algae bloomed, and of course died after using up nutrients in water. the dying algae started rotting displacing oxygen, killed many fish. Thats just 1 of many times I had to learn the devil is in the details, I didnt even think to factor less water would warm faster.
No streams or creeks from closest city 10 miles away Sanford,NC our whole county only has about 60,000 in it, Persons per sqare mile in Lee county, NC is like 227 and that is averaged including the city. I have no worry of biohazard contamination of our water. I do have to worry with Fort bragg being so close, to a fallout contamination issue if that scenerio played out, but then truly all one could do, (IF the government even warned us) would be pop the top on one of grandpaws jars of peach mountain dew, grab a lawn chair, and catch the last show.
