CA Flooding - Balsa Storage Question

So more of a statement than question, but will get to that

Blah Blah Blah, NorCal is flooding, horror, trauma, blah blah - More news at 10
Decades ago, George Christian, LBJ's press secretary, had an office in same building I worked.
one day I was bemoaning to a pal "the press lies, they only sensationalize, they don't report the news"

Mr. Christian overheard us and said "Boys, the job of the press is not to report the facts, its to sell newspapers"
I'll never forget that.

Anyhow, yes, it is raining here, trees have fallen down, homeless who made camp in creekbeds were washed away
Me? I'm fine. I bought a simple house built in 1902 on high ground. Its survived floods, earthquakes and now me.

BUT! in response to all the flood hysteria, I went to the dry warm basement, picked all my balsa and tissue up, and moved it from 1st shelf by floor, to 3rd shelf closer to ceiling.

Most of my balsa long stock strips are stored in 3" PVC Pipe, 3' long, with slip fit cap glued at one end, just fit at the other.
I realized, I need more storage. So I thought I'd buy some 4" PVC, upgrade the holders where i have more stock, then roll and store tissue in the 3" tubes

HAVE YOU SEEN THE PRICE OF PVC lately?
10' 4" pipe = $55!!
4" end caps = $14 each!!!


So heres my question - how do YOU store YOUR balsa strip wood to keep it safe, dry and accessible?
