Yes, in places, and the places are specific rather than general. Roughly one postcode in six sits in the river and sea flood zone. Seven in ten are within 500 metres of the coast. Nothing on record says the town has ever flooded. This is not somewhere the water is a distant possibility, it is somewhere the water is at the end of the street and has so far stayed there.
The Environment Agency's river and sea mapping puts about 16% of the area's postcodes in flood zone 3, the highest-probability band, and about 1% in flood zone 2, the medium-probability fringe that lies beyond zone 3 rather than wrapping around it. The smaller number being the outer band is the mapping working correctly, not a contradiction. For a town at the head of a tidal creek that runs six miles to the sea, a sixth of the postcodes in the top zone is geography rather than misfortune.
Surface water is not published as a separate share for this area. It sits folded into the combined postcode indicator below, which means an address can rate badly for run-off and drainage without appearing in either river or sea zone. That is the gap most buyers fall into, and the only fix is checking the specific address rather than the town-level figure.
Applying the standard climate allowance pulls about 4% of postcodes into a zone they are not in today. That is a forward look already built into the mapping, not a prediction of any particular flood.
Where this bites first is insurance. A high-band address attracts questions, a heavier excess on flood cover, and occasionally a decline from a mainstream insurer. Getting an indicative quote for the actual property before instructing a solicitor costs nothing, and completion day is a poor moment to discover the premium.
Taking all the measures together, on at least one of them, rivers, sea or surface water, about 23% of the area's postcodes rate high, about 10% medium and about 23% low. Those bands overlap the zone figures rather than adding to them. The same postcode can appear in both, and frequently does.
Counting homes rather than postcodes sharpens it. Across the 56 postcodes that carry any rivers-and-sea risk at all, and only postcodes with some risk appear in that dataset, there are 1,254 properties: 220 at high risk, 55 at medium and 134 at low. Of the high-risk properties, 78 are residential. In a town this size, that is a number people could put addresses to.
The modelled extents answer the question buyers actually care about. About 12% of postcodes fall inside the high-risk extent with defences included in the model, and about 12% fall inside it with defences stripped out. The defences move that share not at all. Present in the model means present in the model, and never means a particular house is protected.
The water is close throughout. About 69% of postcodes sit within 500 metres of the coast, which is a threshold the data defines rather than a statement about any one address, with a median distance of about 355 metres and a closest measurement of one metre.
The shoreline management policy along this stretch is hold the line, at the twenty, fifty and hundred year horizons alike. That is a stated intention to go on maintaining defences, signed by people who will not be around to be held to the hundred-year part. It is not a defence that already exists and not a commitment that the money will be there.
At the nearest tide gauge, Devonport, sea level rose about 2.35 millimetres a year across the 1962 to 2015 record. That is a measured historic rate rather than a projection.
No historic flooding is recorded here at all, which counts for something real. It is not proof of anything, because records only start once somebody begins keeping them, and a settlement that grew up around a bridge built in or before the tenth century has weathered a great deal that nobody wrote down.
On flooding, Kingsbridge sits worse than most places, with the risk loaded onto the streets nearest the water rather than spread thinly across the town. Which side of that line a house sits on is an address-level question, and it wants answering before the offer, not after.
