Flooding has changed the culture of the area, and also the rebuilding and development process after the flood.
Fortunately I was looking from afar at the time of the Brisbane floods as I was north of Mackay where peole had similar problems but for different reasons. There was no looting to my knowledge but the enviromental impact left it’s own form of stealing in that many home and business owners lost almost everything as did many of the farmers and particularly those involved in banana production. Addressing growing concern over climate change, Remistudio’s massive floating Ark can battle rising tides. Combining the ark idea with the farming idea (the lower structure adds stability making it much less likely to overturn in a large wave), would be a great idea for stable oceanic housing. As Vicki Arroyo says, it's time to prepare our homes and cities for our changing climate, with its increased risk of flooding, drought and uncertainty.
In the following image notice how well the estimation of flood water height corresponds with the amount of sandbags. That’s the approach behind the Water-Scraper, a futuristic self-sufficient floating city. Water resistant materials and forms of construction may be a material consideration and a requirement of planning permission. Where it is intended to develop in areas that may be at some risk of flooding, guidance on precautionary measures that can be taken is given in 'Design Guidance on Flood Damage to Dwellings, 1996 published by HMSO. This document describes the likely effects of flooding on materials and elements of the building and assesses various forms of construction and measures to reduce the risk of flood damage in dwellings. This section explains how water affects different materials and forms of construction, and indicates the factors to consider in the choice of materials and how the requirements of the Building Standards can be met.EFFECTS OF FLOODWATER ON BUILDINGS82. We maybe have to rethink – maybe this concept of Queenslanders raised up is a good idea in flood prone areas. Following a flood, external walls will be dirty and may be permanently stained if not cleaned.
In addition solid concrete floors generally suffer less damage than suspended floors and are less expensive and faster to restore following exposure to floodwater.86.
In the case of coastal flooding, salt water may cause surface powdering and flaking of soft brickwork. Regulation 8 requires that materials, fittings and components used in the construction of buildings should be suitable for their purpose, correctly used or applied, and sufficiently durable, taking account of normal maintenance practices, to meet the requirements of the building regulations.
The EC is introducing durability requirements into European Standards (ENs) for construction products. Simple measures are unlikely to prevent water penetration for more than a few hours while more complex solutions may protect the building for a day or two.Wet proofing assumes water will enter the building and is based on the use of water resistant and resilient materials within the building and the raising of electrical wiring and sockets above the maximum flood level. Wet proof construction should also allow water to drain easily from the building following a flood and not retain it in walls, floors and air pockets within the building footprint.94. It may be advisable to raise ground floor levels above the expected flood levels and this could affect other issues such as accessibility. In most cases additional pumps may be necessary to remove floodwater that may seep around a barrier. Temporary removable household flood products fitted to individual buildings help prevent water entering through doors, windows, air-bricks and vent covers. Several temporary flood protection products have successfully achieved national standard performance criteria (BSI 'Kitemark' standard). Floods are the most dangerous disaster in terms of human lives lost and property destroyed. This year’s snow pack in the region was 36 per cent above normal, and early forecasts called for a low to moderate risk of flooding. Ask your plumber about whether a sump pump or zero reverse flow valve in your basement floor drain will protect your home from flooding.
Don't walk through floodwaters; you can be knocked off your feet by 15 cm of fast moving water. Keep small children, pregnant women and people with health problems away from the flooded area until clean-up is complete. Listen to your radio and television for information and updates about assistance and clean up programs.

As the UK continues to experience varying levels in the severity of its’ weather and climate, it becomes increasingly important for businesses of all sizes and types to protect their people, livelihoods, assets and property from the risk of flooding. In this section you will find some practical tips and guidance with regards to safeguarding your organisation, ensuring that you integrate any plans or procedures as part of your business continuity plan for consistency. That flood peaked at one metre above the flood stage, and half a metre over the previous record flood.

A special mention in the eVolo Skyscraper Competition, the design expands the concept of a floating island into a full-fledged underwater skyscraper that harvests renewable energy and grows its own food. Even in the United States, ground zero for climate change denial, six in ten Americans say they believe it is indeed happening.
Floodwater can penetrate buildings rapidly, causing widespread damage to floors, walls, finishes and services, and structural damage in more severe floods.
Contaminated sediments may be deposited on site and these must be removed.Damp conditions following a flood may lead to the growth of moulds that can damage the building and present a health hazard.
Mineral fibre and other absorptive insulants will retain water and can lose their insulating properties or disintegrate over time.Source - Design Guidance on Flood Damage to Dwellings, The Scottish Office, 199687. For example, external timber cladding for low-rise buildings that is readily accessible and replaceable need not be as durable as that which is to be used at a higher level on medium rise buildings.89. The ABI has recently prepared guidance on flood resilient homes and the cost and effect on future insurance claims of installing flood damage resistant measures. This is the most practical approach and there are a number of ways to limit the damage from flooding.
Further advice on the suitability of different materials can be found in Preparing for Floods, February 2002 published by ODPM.
Early discussion with the Planning Authority and Building Standards is encouraged for any site where there may be conflicts between planning and building standards requirements.TEMPORARY FLOOD BARRIERS99. Floodwater may be substantially prevented from entering through building fabric with a flood 'skirt' which is designed to wrap around a building. Know what flood warnings mean and check the specific warnings for your area on a regular basis. That changed a couple of weeks ago, however, when hot temperatures spurred glacial melt and caused water levels to rise by about 10 centimetres per day for several days.
Move pesticides, weed killers, fertilizers and other articles that may pollute flood waters to a higher level in your home. Assume everything touched by floodwaters is contaminated with dangerous chemicals and germs.
Flood Preparation for Business – The Environment Agency has published some excellent guidance on preparing and protecting your business from flooding. Planning Advice Note PAN 69 Planning and Building Standards Advice on FloodingWATER RESISTANT MATERIALS AND FORMS OF CONSTRUCTION79. Sophisticated molecular analysis of the ice can reveal the temperature at the time it formed. They are also likely to be applicable when buildings are being reinstated following a flood.80. So we need to look for opportunities and creativity and innovation to rebuild so that we are better prepared for the next flood. Buildings with excess moisture, poor ventilation and those exposed to standing floodwater can be breeding grounds for moulds. There are two basic approaches that may be appropriate for the protection of buildings against the effects of flooding:Dry proofing aims to prevent flood water from entering a building. Timber joists and floor boards can be treated with preservative to ensure they are more water resistant and to permit them to dry out faster after having been immersed in floodwater.
Temporary flood barriers will help to reduce the rate at which floodwater comes into a building but will not offer complete protection from flooding and are not an alternative to robust building techniques.

The maximum height for a temporary flood product fitted to a building should be no greater than 1 metre above the ground surrounding the building.
If you live in a flood-prone area, it is advisable to put together an emergency kit for use in times of flooding and a checklist of items that you need to take with you if you evacuate. Should flooding events in the region become more frequent and more severe, and long-term planning become necessary, that responsibility would fall to another branch of the government, said Templeton. National Geographic: No other kind of natural disaster in America has caused more death and destruction than floods.
Once you bounce back, then you have to start planning for the next flood, because it IS going to happen. For example, poor construction techniques and some common bricks are very porous allowing water to penetrate very quickly to the building interior.
Some materials, such as concrete, can be both resistant and resilient, for example solid concrete floors can provide an effective seal against water rising up through the floor, provided they are adequately designed. Dry proofing a building however can be difficult and is unlikely to work if buildings are subject to flooding for long periods. Many suspended timber floors in modern buildings have mineral wool insulation between the timber joists.
It is important that temporary barriers are fitted properly and in good time in preparation for a flood.
It’s a good idea to know exactly where the shut-off valves are for your electricity, gas, and water supply lines, so you know where these are before a flood occurs. Flooding can be caused by heavy rainfalls, a quick snow melt, a burst dam, or a violent storm.
Even with measures to flood proof buildings, water will tend to find its way through weak points within the wall such as cracks and voids in the mortar jointing, brickwork or rendering.
This material has poor flood resistance closed cell insulation should be used.Drying out97. In upland areas the lead time between flood warning and the flood event may be short so it is important that any barriers are available for rapid deployment and are simple enough to be installed by the home owner. The current forecast shows the water level reaching what officials call “flood stage,” or the level the Southern Lakes reached in 2004. Flood proof your home by ensuring downspouts drain far away from your house and that soil slopes away from your foundation. For semi-detached and terraced houses floodwater may also seep through party walls with neighbouring properties, above or below floor level.83.
If suspended floors are used, some form of access for inspection and drying out of the underfloor area should be provided. However, the lakes may peak above or below that level depending on the weather conditions for the rest of the summer.
The processes and pathways by which water enters a building during a flood depend on the characteristics of the flood - specifically flood depth and duration, and water velocity.
The use of a sump and an identified drainage point where a pump can be installed to drain any flood water should also be considered.Solid concrete floors98. Groundwater flooding results in water entering cellars and voids beneath floors causing problems of damp in walls.
In flood prone areas solid concrete floors are generally considered more resistant because they prevent water accumulation beneath the floor level. In general terms:Shallow floods will penetrate "weak" points in the building such as air vents and cracks in brickwork, and will overtop doorsteps. The use of flood barriers such as sandbags or proprietary flood proofing systems will merely delay the penetration of water.Deeper floods and faster flowing water are likely to penetrate the structure of buildings more quickly.
There are also secondary effects of floodwater on building structure and the health of the occupants.
Watercourse, coastal and sewer flooding can lead to the contamination of flooded properties.
