Yes, in parts, and the river decides which parts. About one postcode in seven sits in the highest-risk river flood zone. Nearly a third rate high on at least one flood measure. Most of the homes at risk are at high risk, not borderline. Sturry has a flood edge, and the listing photos won't show you where it runs.
In the Environment Agency's river-and-sea flood zones, about 15% of the area's postcodes sit in Zone 3, the highest-probability band. Another 5% sit in Zone 2, the medium-probability fringe outside Zone 3. The two bands don't overlap, so Zone 2 being smaller just means the edge between high risk and none is narrow. The Great Stour runs past the village, and here that's the source that matters, not the sea.
Surface water doesn't have its own separate figure for Sturry. It's folded into the postcode-level indicators, alongside rivers and the sea. The record shows the river has already done it: the Environment Agency lists 16 recorded flood events, the most recent in February 2001, when the main river overtopped its channel where there were no raised defences. About 5% of postcodes fall inside recorded historic flood outlines. About 15% sit in the River Stour (Kent) Internal Drainage Board's district, which manages water levels on the low ground.
The forward look is less comfortable. With the Environment Agency's climate allowance applied, about 30% of postcodes fall inside a flood zone. That's the planning system's view of how the map could look with a wetter climate, not a prediction for any one house. Buyers planning to stay twenty years should read that figure, not today's.
Insurers price from the same kind of mapping, and a house in or near Zone 3 can expect more questions, higher premiums or a larger flood excess than one up the hill. The quote a buyer gets on a riverside house tends to say more than the estate agent's description does. Get it before the survey, not after exchange.
On the postcode-level indicators, which count a postcode if it rates on at least one measure, surface water included, about 30% of postcodes rate high on at least one measure, about 18% medium and about 32% low. These bands overlap with the flood-zone shares and can't be added to them. They're a wider net, which is why the numbers are bigger.
Counting homes rather than postcodes, the Environment Agency's rivers-and-sea mapping lists 351 properties in the 35 postcodes that carry some risk at all. Of those, 181 are at high risk, 16 at medium risk and 72 at low risk. Postcodes with no mapped risk don't appear. The telling part is the shape: at-risk property in Sturry is mostly high-risk property, not a large margin of marginal cases.
On whether anything stands in the way, about 15% of postcodes sit inside the high-probability flood extent with defences left out of the model, and about 15% with defences included. The two figures are the same. "Defended" only means a defence is present in the model, and here including it doesn't shrink the high-risk footprint. Nobody should read the word "defended" on a search result as meaning dry.
The sea is a secondary concern. The nearest coast is about 7.5 kilometres away at the median, and the shoreline management plan for the coast here is to hold the line over 20, 50 and 100 years. That's a stated intention to maintain existing defences over those horizons, not a guarantee, and not a new wall. The nearest tide gauge, at Dover, recorded sea level rising by about 2 millimetres a year across its 1961 to 2010 record. That's a measured historic rate, not a forecast.
Before offering on a house here:
- Put the exact address into the Environment Agency's long-term flood risk service, not just the postcode.
- Get an indicative insurance quote, including the flood excess, before instructing a solicitor.
- Ask the seller directly whether the property has flooded or made a flood claim.
- Check whether the house sits on the low ground near the river or up on the northern estates.
- Have your solicitor order an environmental and flood search as part of conveyancing.
Flood risk is Sturry's weak point, and it isn't a small one. The high-risk homes are real, they're concentrated near the river, and choosing the street carefully matters more than the price.
