Some, though nothing dramatic. It lies in the medium-risk fringe of the river flood map. More than half its postcodes are in that fringe. None are in the highest-risk zone. No flooding is on record here. The map is where most of the risk shows up, and the climate version of it covers almost the whole place.
On the Environment Agency's river-and-sea mapping, 54% of Ashford Common's postcodes are in flood zone 2 and none are in flood zone 3. The two zones are separate bands. Zone 3 is the higher-probability core, and zone 2 is the medium-probability fringe beyond it. Ashford Common has fringe and no core. Counted by property instead of postcode, the Environment Agency rates none of the 2,538 homes and buildings it lists here as high or medium risk from rivers and the sea. It rates 1,357 as low risk and 630 as very low.
Surface water, the rain that floods streets before any river rises, has no separate figure here. It is included in the postcode indicators further down, which is the best measure of it available for Ashford Common.
The Environment Agency's climate-adjusted flood zone covers 98% of the postcodes. That map looks ahead to how river flooding could spread as the climate warms. Today's fringe becomes almost the whole place. "Outside the high-risk zone" is accurate today. Particulars that leave out the climate map are describing the present only.
Insurance is where zone 2 shows up first. Most homes here should be insurable without trouble. A flood-zone flag can still change which insurers will quote and what the excess is, and that varies from house to house. Put the exact address into the Environment Agency's long-term flood risk service, and get a buildings-insurance quote on it early in the purchase.
The postcode indicators combine rivers, sea and surface water, and a postcode counts if it rates at a level on at least one of them. On that basis, 3% of Ashford Common's postcodes rate high on at least one measure, 14% medium and 67% low. These bands overlap with the flood zones above and measure something different, so the two sets of percentages should never be added together. The small high-risk group comes from the combined measures, since the river map alone puts no postcode in its top zone.
The defence question barely arises here. The Environment Agency's modelled high-probability flood extent covers none of the postcodes, either with defences in place or without. A low-probability extent covers 57% of postcodes, and none of that has a defence in the model. "Defended" only means a defence appears in the model and would say nothing about whether a house stays dry. Here, there are no defences to mention either way.
The nearest tide gauge is at Portsmouth, where sea level rose by about 2 millimetres a year between 1962 and 2023. That is the rate measured at Portsmouth over those years, and it says little about how flooding behaves this far inland.
No historic flooding is on record in Ashford Common. That is reassuring. It covers recorded flooding only, so a wet garden from decades ago may simply have gone unrecorded.
Flood risk here is low by most measures and better than average overall. The one thing to watch is the river map's wide medium-risk fringe, which the climate allowance stretches across almost every street.
