Cob: RE: Flooding questions

IMHO, it could handle a day with no problem. I had an arch using earthbags / superadobe, with no stabilizing ingredients. (e.g. no cement, just clay and sand). I was exposed and it rained for a good week here in Georgia. It finally collapsed but it took a week. Thus I think that one day would be fine. Besides, if you just got hit with a 100 year flood, should be good for another 100  :-)

Subject: Cob: Flooding questions

I hope I'm not being a pest here, but we just had a 100 yr flood here in Vegas and it has prompted some questions.  A friend of mine (the same one who wanted to build the goat shelter) and her neighbors, who were NOT in a flood zone (and therefore couldn't have purchased flood insurance if they'd wanted to) got flooded because nearby highway building messed up the flow of water so it didn't go where it was supposed to.  She had water a foot high on her walls for five or six hours, one neighbor had water, mixed with manure from a neighboring farm, 3 feet high.  

I have two questions:
Would standing water for several hours be enough to collapse the walls of a cob home?

How cautious should you be with building?  I suppose a stemwall several feet high would definitely protect from this kind of situation, but is it worth the extra work when you have no reason to expect to need it?  How paranoid should you be when planning for eventualities?
Thanks,
Rachel
