Thanks for the questions and pointers!
The HOA would restrict a permanent structure without approval (even though there are some greenhouses in this HOA which have been approved), but the bigger problem is that I would have to take it to the field, which is in the flood plain and prone to flooding once every few years. But there are some new, interesting vertical techniques that I am reading about, that might could be built on a trailer-base, and moved as needed (temporary structures are permitted).
The HOA restricts hunting through fines, but the area is unincorporated and is legal. I can actually hunt on the river bed, the neighbors may not like the gunshots, but there is no recourse. And my guess is that when people are hungry, the fines are not going to matter too much, and the artificial restrictions designed for normal times will be lifted.
No livestock or farm animals allowed, except a horse, but the flooding problem is an issues because a fence will eventually be swept away. But again, I believe the HOA rules will go out the window if the SHTF, and I will be looking for chickens.
I have some entertainment, rechargeable lanterns, and such, but probably need some work in this area.
Lots of room in the field to bury things, especially things that will help the garden flourish. No control over the river, as it is very far upriver, and goes all the way to the coast. My neighbors on either side have pools (one elderly), and I hope to work out some type of exchange, even if it is providing security. For the filter, I have smaller filters, but am considering this fairly new device, a Lifestraw community water filtration system.
Cleaning supplies I need to stock up on more. Thanks for the tip!
I do not have an sand “bags” but I have an unlimited supply of sand from the river bed. I do not know how to make quicklime, but there is literally tons of limestone in the river bed. I foresee a community militia forming if the SHTF, because our county sheriff department is small, and they will have their hands completely full in the rest of the county.
The dam is about two miles upriver, and if it breaks, this place is in big trouble. Hopefully there will be some warning, then my bug-out place will take effect. But if it happens in the middle of the night with no warning, getting to the roof of my two-story house will be the only hope (which can be done from the inside of the house).
