By this I don't mean "keep the water out" as I suspect that this is actually
very hard to achieve. I'm thinking more of waterproof non-absorbant walls
(possibly tiled) downstairs, all electricty cables coming from upstairs (or
from the loft) *down* rather than from under the floor up, solid concrete
floors downstairs and maybe even a floating "raft" floor on top of the
concrete floor for your furniture that would float on top of flood waters
keeping your valuables dry.
How much of the above is practical? Would it be terribly expensive? What
other measures could one incorportate to make recovery from a flood in a
flood prone area just an inconvenience rather than a disaster?
Tim
I recall a program where someone had done just that. It seemed to work
well. Tiles for the first 3-4ft downstairs, Electrical sockets further up
the walls. I can't recall what they did about kitchen units, unless the
kitchen was upstairs. I also know of a pub which is regularly flooded,
though I expect they have far more stainless steel items. Each time it
takes 3 or so weeks to re-open. Where there's a will there's a way.
Er - apart from your "floating raft floor".
I suppose the ultimate is what they have done, in the so called third world,
for years in flood prone areas - houses on stilts.

Wonder how *fast* the water comes in in situations like this? i.e. would
concrete floors and a drainage channel around the perimeter, leading to a
sump/pump do the job - or would the pump just get overwhelmed? (There's
the issue of where to pump *to* of course!)
Houseboats?
But we live in a world where planning control give a maximum roof height,
which tend to make the ground floor lower than it should be. I know of one
building which was flooded as a direct result of this.
Flood resistant houses with tiled walls and electrics installed at
first floor level are common in the Netherlands in areas where
achieving the national standard of protection against flooding is not
practicable.
Everything from water gently lapping up at your house and rising
imperceptibly slowly, to mudslides and tidal waves.
Sewers overflowing back into properties is a particular danger (in
emergency use sandbags in the loo), so automatic valves or "sea
toilets" may be necessary.
Actually a very good idea. If you live on a flood plain it makes perfect
sense.

There was a suggestion on telly after a previous round of floods of a
giant condom which you raised around the house as water approached,
but I bet you'd then find the rubber had perished at the folds.
Another idea from Holland shown around the same time was the whole
house built on a raft that floated up and down on poles.
The real solution, if you insist on living in a flood plain, is to
live upside-down, i.e. the living space with its expensive electrical
goods and irreplaceable family treasures are upstairs, and bedrooms
and bathroom downstairs. Keep a pile of black bags in the bedrooms
ready to get the clothes upstairs PDQ and use rugs not fitted carpets.
Water alarm in case it comes at night.

Garage at ground level under the rest of the house. The car's going to bite
the dust anyway - at least it would be the only thing of significant value.
Easier to hose out a garage and buy a new car on insurance than deal with
the mess those poor sods are finding.
Problem that some people overlook is flooding isn't just about a bit of
muddy river water coming up - by the time that happens, the sewers are
breached and you've got crap everywhere - as one report put it, after the
waters had receeded, "the street was littered with faeces" (amongst other
things).

There's a fairly standard design of "town house" that has a garage on
the ground floor with all living accom on 1st and 2nd.
Disabled access is a bit of a pain though. And who here would want to
risk losing all their valuable junk in the garage?

1 - Exactly.
Downstairs bedrooms.
- Concrete floor, cheap laminate & roll up rugs
- Tiled or textured UL94V0 plastic walls
- Acoustic tiles on ceiling to restore acoustics
- Sockets & lightswitches IP66 glanded drop
- Automatic flood valve on toilet
- Understairs tanked to ceiling, shelves for bedding, clothes, flood
pump & door seal
Cleanup aids.
- Central drain for house/room
- Simple hose-down, disinfect, dehumidify
1st-floor.
- CU and even DNO cutout on 1st-floor
- Possibly block n beam construction
- Possibly steel stairs with inset wood
A blend of modernist, minimalist & practical.
2 - Removal of PP restrictions on height to permit more logical 80cm
floor height.
3 - Dredge the ruddy rivers properly
Victorians built much of the UK 's infrastructure AND regularly
maintained the rivers, we are not doing this. We are treating the
effect with multi-million pound barriers pushed by enterprise rather
than civil servants tackling the cause and being held to account for
not doing so. We are failing to manage waterflow just as we failed to
manage transportation.
USA is about to hit the same problem head-on, monumental amounts of
bridges, roads even basic utility structures across America are in
dire need of repair, replacement & maintenance. It too is about to
find "post-empire" is an expensive world of compromises.
4 - Downstairs Contents Insurance guaranteed to £2.5k
"Upside down" house should be able to secure specialist cover of £2500
for £100/yr, perhaps varying £50-200/yr. Indeed one could say the same
is true for "normal" houses - it comes down to risk, insurers like too
easy a life.
New Build on flood plains which has been rampant under New Labour
really should have been "upside down". Instead we have had "build
anywhere without due consideration of the risks, feel the finance in
your fingers not the water round your toes".

Vanishingly small is true for us but for a location less than 20'
above the normal water level it's anything but.
Build in that zone and the chances are you will get flooded at least
once in a lifetime. If you are only a foot or three above the water
level then you'll get flooded far more often.
The simple answer is don't build on flood plains. But if you have
been daft enough to do so live it. Don't come crying to me post flood
because "they" didn't warn you, "they" haven't built adequate
defenses, "they" won't insure you. Want that nice riverside
appartment, don't buy the ground floor one...

The Victorians didn't pave huge areas so the water would run off into the
rivers as fast as it fell from the sky.
The Victorians didn't build big barriers on the sides of rivers that made
the huge volume of water flow down stream too fast for the downstream areas
to handle.
The Victorians didn't build on flood planes.
I have little sympathy for people that decide to live on existing flood
planes.
I have a bit of sympathy for those that find they are on a new flood plane
caused by someone "fixing" an upstream problem.
The best solution is to demolish the houses that keep flooding.

I was thinking: knock down the house and build an ark that sits on the
same foundations. Tethers short enough to keep it in the plot, but long
enough to rise, say 20ft - keep bolt croppers handy to cut loose if
necessary. Gas water and electricity through self-sealing
connectors. Probably avoids the Building Regs too.
Noah.
A guy out in the countryside a couple of miles from me (lower down so
more risk) bulldozed a berm around his bungalow. When you drive into
his yard you go over the berm and down the other side into the
protected area. He has a garden pond with a pump in it to deal with
seepage by collecting and then putting excess water back outside the
berm. Being in a rural area has its definite advantages!
My own place remained well above the water level in June 2007 so I
figure I am relatively safe, especially since our local Internal
Drainage Board were kicked into properly desilting the main dykes down
to the river after the floods (first time since 1982). A small number
of riparian owners between the village and the main drains are still
frantically making excuses but the county council will soon be going
in with machines and if there is any justice the culprits will be
charged for the works rather than the council tax payers.
Well, aviation - at least powered - was pretty new back then I suppose.

Which would probably fall foul of the disabled access requirements in
the building regulations.
What requirements? That we don't build "town house"s on 3 floors?

Or a three-storey townhouse design with the garage and entrance the
only things on the bottom floor. If floods are predicted, the car can
be removed to higher ground, then everything else should be safe (so
long as it isn't used for junk storage).
Neil
I've also seen it done in an expensive looking house beside the Thames.
Colin Bignell
That's easy. Front door at ground level, and behind the front door steps up
to the living quaters. Where there's a will there's a way :-)
Why can't cars float? On second thoughts, thousands of cars floating
out to sea might be a liability.

We had exactly that problem we were offered a house (few years ago
now)with a 'main door' at street level (son is disabled we needed the
ground floor ) the door was on street level but just inside the door was
a flight of steps up to any habitable areas, above shops. This was not
counted as a serious offer as although advertised as a ground floor
house we, successfully, argued that there was no ground floor and it
should actually be listed as a 1st floor dwelling.

There's a house a few miles from me that's entirely up on stilts. Car
parking and garage/storage underneath and a bungalow above with a really
nice deck around it - long before they became common. In fact, the deck
is a car ramp, iirc.
It's miles from any likely source of flooding, though.

Which struck me as the solution for future flood damage avoidance in
areas likely to get it again. Problem with Cockermouth was the
unexpectedness of it, but in many areas the above idea should be put
into practice. Of course, as time passes and the memory recedes, folk
would go back to having the expensive gear on the ground floor again.

Nor did they drain huge acreages of land. The loss of much of the
natural sponge of the countryside is a direct contributor to much of
this trouble.

Sky News, November 2035
Lifeboat and tug crews have been out all day recovering the town of
Cockermouth from the Irish Sea.
"It's been a grand day out," said Ivy Till, as she steered her 3-bed
apartment back to land.
I have actually toyed with the idea, even before the recent floods. The
ground floor would have thick reinforced concrete walls, to give the
strength to resist the pressure of the water. I did assume that 2 metres
protection would be sufficient, although I'm not sure it would have been
in Cockermouth, so the ground floor rooms would only have windows above
that level. Obviously, that means the living quarters would need to be
at first floor level. The entrance would be at ground floor level, with
steps and an hydraulic lift to the first floor, and would be completely
lined with impervious materials. There would be a standby generator and
foul water would be pumped to a header tank, well above flood level, so
nothing could come back up the drains. The garage I planned to build on
a pontoon, which I intended to be guided and restrained by vertical
posts, so it and anything in it would float. I did also consider fitting
a waterproof door at ground level, which would make moving furniture in
and out in normal times much easier.
Colin Bignell
It would be a bit unattractive though, everyone having to have old
tyres round the circumference to stop the house bumping into the
neighbours.

Big doors at first floor level and a Dutch style hoist

Sounds like a Queenslander. They were designed to keep cool with no

It's a bit inconvenient having to shin down a rope to go to work,
though. And hauling the missus up to first floor level with the
weekly shopping using a block and tackle sounds like hard work.

Very much like that, but more modern, and almost Italian in style. As I
say, you can drive a car up the ramp onto the deck, but I'm unsure if
there's enough room to turn or whether reversing is necessary - perhaps
there's another ramp at the rear. It's a really nice house and would be
perfect almost anywhere, but especially in Cork or Clonmel.
Or a DUKW if you have a large family...

May as well go the whole hog and make it a floater.

Aye, getting the sponge back is one of the reasons the North Pennines
ANOB is spending quite a bit of money in blocking up the grips cut to
drain the blanket bog just after WWII. Not that this would have
helped along the Derwent/Cocker but it will help the Tyne and the
Wear.

It'd make far more sense practically to put keeping water out first and
build traditional houses with a step or two (or more) up to the front door.
Then have a fund so that anyone who is or becomes disabled can have a ramp
or other appropriate access fitted rapidly and free of charge whenever they
want to move. This would also open up the existing housing stock for anyone
with such a need. I also dislike ramps not only because they take up so
much space, but because they are dangerous for the able-bodied in wintery
weather. Incidentally, in my local town centre, the bank was recently
extended into the shop next door and although there is a very wide
pavement, they did not take the option of putting a ramp outside, running
along the front of the building, with steps at the high end, so that people
could choose which to use - instead they ramped the whole pavement, making
a dangerous slope in the winter where it was previously flat.
SteveW
> Problem with Cockermouth was the unexpectedness of it,
Pardon? The Met Office had a red weather warning out on the Tuesday
IIRC, a red weather warning means "take action". The warning forecast
250mm of rain over the fells.
The EA had Severe Flood Warning for the Cockermouth and several other
places on Wwednesday evening. A Severe Flood Warning means "Severe
flooding is expected. There is extreme danger to life and property.
Act now!".
Or by "unexpectedness" do you mean the fact that the waters rose so
high in just a few hours? 'Cause even that shouldn't have been
unexpected, the fells were already saturated, the lakes full any
freash rain would just run off and run off fast as the Lake District
isn't exactly flat.

Mostly that, I suppose. From what I read I see there was a flood in '05,
and that should have girded some loins, but ho-hum. I don't suppose most
people there expected this one to go as high as it did.

After a period of prolonged heavy rain, a house near me developed

After 2005, the locals girded their loins and worked very hard to
persuade the Environment Agency, against much opposition from nature
conservationists, to dredge the river in order to increase its flow
capacity and reduce the risk of flooding. Because of the opposition
from the conservationists, persuading the Agency took several years.
The Agency finally caved in in the summer of 2009 and the work was
programmed to take place in late spring/early summer of 2010.
>I don't suppose most
>people there expected this one to go as high as it did.
The problem is that too many warnings are given, and the warnings are
often too severe (understandably erring on the side of safety). When
the floods don't happen, people become complacent. So when they get
*yet another* severe warning, they perhaps don't react as they should.
Where there's a Will he's usually being fired at until they run out of amo.
firing at Wills is just another tpye of 'ism it should be outlawed ;-)

Trouble would seem to be that they behave to some extent like the
houseboats they are derived from, IE storms and hurricanes treat them
like playthings.
