    Default Flood preparation boats .

    I've been visiting various businesses around my town today, we recently had a very serious flood, not all of the town was affected but some areas were badly damaged. I visited my friend the electric power tool repairer and auto electrician today. He got off lightly with only 2 feet of water in his workshop but everything on the lower shelves or the floor was soaked in muddy water.

    I've been suggesting "boats". Tiny nesting boats say 6 foot x 4 foot with 12 '' sides stitch and glued together. Own 6 of those and you could put 1000 pound of stock or equipment in each one , inside on the workshop or shop floor. As the water rises the "boat " does too. 6000 pound is a lot of lifting .

    The idea is that business owners could have a stack of them somewhere on the premises but when flood threatens ....and there is usually some notice, they could be deployed.

    I think I'll volunteer to make a few.

    Good idea. Not boats as such. but watertight crates with adequate stability.

    Make them strong enough to be manually or fork lifted when full.
    It really is quite difficult to build an ugly wooden boat.

    That would require something much heavier than I'd imagined but a couple of cleats on the bottom to get forks under would be a good idea.
    Thanks.

    Some one is bound to want to pick them up when part loaded, human nature being what it is. Make them strong enough to withstand what two people can lift.

    Was that a 50 year flood?

    Meaning you have 49 years to go to use anything you build this year?

    We get a couple of 50 year storms every year these days. Only going to get worse.

    Nope it don't work that way.
    It means a 99% probability that it will recur on average once in 50 years. The on average bit means that it could be twice this year and then wait 90 years for it to happen again. With Global Wierding, the magnitudes of the 10, 50 and 100 year events will become more extreme and smaller events more frequent.

    The frequencies are certainly increasing . This one was 28'' or 800 mm of rain over 4 days, it's 10 years since we had one like that.

    Like Nick said,
    its not a prediction of 1 per xx years.

    California just got out of a drought, but historical record says those come along at irregular intervals.
    Doomsayers don't want to recognize that.

    Well, I'd be happier with a description of a 1 in 20 year flood, this 1 in 100 thing is just silly.

    A quick Google suggests that your authorities may use a 1% annual exceedance contour, which is equivalent to 100 year exceedance event

    However this flood overtopped the 1954 record level making it the worst flood on record.
    My take is that if you poke someone with a sharp stick they'll get annoyed, if you smile and shake their hand they will be your friends.

    You're obviously better at this stuff than I am Nick.

    I would use a standard pallet as the base and 12 or 18mm plywood for the sides and bottom and make them 1m high. Options would include caster wheels (for people without a pallet jack or forklift) and a gasketed lid with hold down latches/toggle clamps. This way the boxes could be used as standard storage for the shop.

    There is also the intermediate bulk container with a cut of top and closed valve. The one way type can sometimes be had for free or very little money.
    200l plastic barrels with screw tops also work well.

    In an existing structure, if you have the ceiling height to work with, I would consider building a 'floating dock' that fills the room. In other words, build a detached floor filled with EPS foam thick enough to raise the contents of the room as the water rises. This would only work where there was a reasonably predictable periodic flooding event where it was highly unlikely to run out of head space. I was thinking of this for someone looking at some possible shop space along the Mississippi in St. Paul.

    For new construction or rebuilding in flood prone areas, I would like to float the idea that houses be built on foam filled dock like platforms that could rise with the floods. [OK, they should generally not be built or replaced at all, but that idea will be sunk by politics.] Some examples" http://inhabitat.com/6-amphibious-ho...cape-flooding/

    Floating houses on fiberglass bases sounds like a great idea !

    An episode of Grand Designs featured a house on the Thames. Concrete tub basically, to float up in floods. But really, for emergency use in a workshop, wouldnt some scaffold and shelving be more practical?
