Mostly not, but the risk that exists sits close together and is serious where it sits. A thin slice of the village is in the highest river-and-sea zone. Nearly one postcode in five carries a high flood flag of some kind. More than half the village lives within a short walk of the water. The village average hides the risk. The address you pick decides it.
On the Environment Agency's river-and-sea flood zones, about 2% of Cuxton's postcodes fall in Flood Zone 3, the highest-probability band, and none fall in Flood Zone 2, the medium-probability band beyond it. The two zones don't overlap, so there is no hidden medium-risk fringe around the high-risk postcodes. On the river-and-sea measure, a postcode here is either in the high zone or out of both.
Surface water has no separate figure of its own here. It is folded into the postcode measure further down, and that measure is why the village's overall flood picture reads worse than the river-and-sea zones alone.
The forward look changes things. When the Environment Agency allows for climate change, about 18% of postcodes fall inside the flood extent. That is the figure that matters to anyone buying for the long term, because it describes the flood risk the house will face over the life of a mortgage, not only today.
Insurance follows the address, not the village name. A home in one of the flagged postcodes can expect an insurer to ask more questions and possibly quote a higher premium or a bigger excess. A home up the valley may never hear the word flood from its insurer. Get an indicative quote on the exact property before paying for a survey, and you'll know which kind of house you're buying.
Counting each postcode by its worst rating across any flood measure, surface water included, about 18% of Cuxton's postcodes rate high on at least one measure, about 13% medium and about 42% low. These bands overlap with the zone figures above and measure something broader, so the two sets of numbers should never be added together. They describe the same village from different angles.
The Environment Agency's rivers-and-sea mapping counts properties rather than postcodes, and it only lists postcodes that carry some risk. Across those, 131 properties appear. Of them, 57 are at high risk, 3 at medium, 5 at low and 1 at very low. Twenty-seven of the high-risk properties are homes. The risk sits in a few postcodes, and those postcodes hold the homes that matter for this question.
Defences are present in the model for some of it. About 2% of postcodes fall inside the high-risk extent with no defence modelled, and about 2% fall inside it with defences included. A defence in the model means something stands between the river and the house on paper. It does not mean the house is safe, and a buyer should read it as a reason to ask about the defence's condition, not as a reason to stop asking.
The water is close. About 58% of postcodes are within 500 metres of the mapped coastline, the nearest is about 36 metres away, and the median is about 446 metres. The 500-metre line is a threshold the data sets, not a verdict on any single house.
The shoreline management plan for this stretch is to hold the line at 20, 50 and 100 years. That is a stated intention to keep maintaining defences over each horizon. It is not a guarantee, and it is not a wall that has already been built.
At Dover, the nearest tide gauge, sea level rose by about 2.2 millimetres a year over its record from 1961 to 2010. That is a measured historic rate, not a forecast.
There is no recorded history of flooding within the area in the data held here. That is reassuring, but a lack of records is not proof that no water has ever come over a doorstep.
Flood risk is Cuxton's weak spot. Most of the village sits well clear of it, but the high-risk properties are real, the climate-adjusted picture is wider, and any house near the river needs checking at the address before an offer goes in.
