Huntley's flood risk comes from rain, and the rivers and sea play almost no part in it. No part of the village is in a river or sea flood zone. Even so, around one postcode in four is rated high risk on at least one flood measure. Nothing on the record shows the village has ever flooded. The danger is surface water running off the land, so the people who need to look closely are anyone buying on a slope or at the bottom of one.
On the Environment Agency's river-and-sea mapping, none of Huntley's 31 postcodes falls in flood zone 3, the highest-probability band, and none falls in zone 2, the medium-probability band around it. The modelled flood extents agree. There are no postcodes in Huntley in a high-probability river-or-sea extent, with defences or without, and none in the low-probability extent either.
Surface water is a different picture. Of Huntley's postcodes, about 23% are rated high on at least one flood measure, about 3% medium and about 39% low. Each of those shares counts any postcode that hits that level on any one of several measures, surface water among them. Since the river and sea maps show no risk, nearly all of that rating comes from rain that cannot drain away fast enough. Over the centuries the village shifted down from the church and school on Brights Hill towards the toll house and the pub, and water also runs downhill.
Allowing for climate change, the Environment Agency's adjusted zone still covers none of Huntley, so the river and sea risk stays at zero on that measure. Surface water is not part of that adjustment.
For insurance, that split matters. Under the river and sea zones Huntley looks clean, but an insurer that rates surface water will see whatever its own model gives for each address, so two houses on the same road can get quite different quotes. Put the exact address into the Environment Agency's long-term flood risk checker, look at the surface-water result specifically, and get an insurance quote while you are still deciding.
On defences there is little to say, because the Environment Agency's models show no river-or-sea flood extent over Huntley, so there is nothing in the model for a defence to hold back. Surface water is not held back by that kind of wall in any case.
Every postcode in Huntley falls under a shoreline management plan, though the nearest coast is about 3.7 kilometres away and the typical postcode is about 4.6 kilometres from it. The policy is to hold the line for the next 20, 50 and 100 years, which means keeping the shoreline where it is now. A policy states what the authorities intend for each period. It depends on money that has not been committed, and it says nothing about what defences exist today. At that distance, the plan covers Huntley because it lies inside the plan's area, and the plan has little to do with daily life here.
The nearest tide gauge with a sea-level record is at Liverpool Georges and Princes Piers, which measured a rise of about 1.4 millimetres a year between 1858 and 1983. That is a long way away and the record ends decades ago, so it only shows what one gauge measured over that period.
No historic flooding is recorded in Huntley. That is good to know, but the record only includes flooding that someone reported. A drain that backs up into a garden may never make it into the record.
Flood risk is below average in Huntley because of the rain, not the rivers, and the share of postcodes rated high risk is too large for a buyer to skip the address check.
