We have a metal carport for the big tractor behind the house and I had to put heavy landscaping blocks close to the back foundation to stop water from running off the roof of that carport, across the yard, and under the house. As far as water rising, it’s not that possible. The road is at a much higher elevation than the creek and the house is much higher than the road. It would take a Biblical flood to get the water high enough to get to the house but I can’t 100% rule anything out.
Flash floods while crossing the bridge over the creek are the main threat in this valley. They raised the bridge years ago and I have seen it close to the new bridge.
We bought a generator after the blizzard of ‘93. Snow will cripple us a lot more than rain. We aren’t set up for snow.
AT this stage in the game you might also consider getting a spare carburetor for the generator and having its jet drilled out oversize to that which would facilitate the use of alcohol (someone may actually make these too, I’ll noodle that).
The Silverado I have I originally got as a flex fuel (E85) vehicle as the whole package was cheap, and I knew that in a TEOTWAWKI situation I could make 1000 gallons of motive fuel with 150 gallons of gasoline. E85 is currently so much cheaper than gasoline (but rising) that I’ve been running it almost exclusively for about a month and a half now.
Also, our E85 pump here states that the ethanol content can vary from 51-83%. It is also 100 octane. If you run any quantity of alcohol in gasoline for engines you definitely want high turnover and/or do not let it set for long periods. Alcohol is very hydrophilic and will absorb moisture from the air over time.
