Is Sticker, Cornwall at risk of flooding?

For anyone buying or renting in Sticker, Cornwall.

Not from a river, and not from the sea. Sticker sits inland with nothing at all in the mapped river-and-sea flood zones. The water that matters here falls out of the sky and goes looking for the lowest gate. A small number of postcodes carry a high rating on at least one measure, and a handful of homes sit behind that number. Flooding in Sticker is a drainage question, not a riverbank one.

The Environment Agency's flood zones cover none of the village. Zero percent of Sticker's postcodes sit in zone 3, the high-probability band for rivers and the sea, and zero percent sit in zone 2, which is the additional medium-probability fringe lying beyond zone 3 rather than a larger circle drawn around it. Two separate bands, both empty. For a place three miles inland from a working town, that is what the geography would lead you to expect.

Surface water is the category that actually applies here, and these records carry no separate surface-water-only share for Sticker. What picks it up is the combined postcode indicator set, which counts rivers, sea and surface water together in one rating. Run-off across sloping ground is exactly the mechanism a river-zone map is not built to show, which is why the zero above is true and incomplete at the same time.

The climate-adjusted zone share is also zero percent. That figure is the Environment Agency looking forward with an allowance for future conditions, and it still finds nothing here for a river to do.

For insurance, that is close to the best starting position an inland village can have. No zone 2 or zone 3 postcode means the ordinary market rather than the specialist one, and no flood loading to negotiate at renewal. Anyone buying one of the few addresses that does carry a rating should get an indicative quote before instructing a solicitor, because insurers price the individual property and not the village sign.

On the combined postcode indicators, taking at least one measure across rivers, sea and surface water, about 9% of Sticker's postcodes rate high, about 9% rate medium and about 36% rate low. Those bands overlap the zone figures rather than adding to them, and they count postcodes rather than houses, which is a unit no buyer has ever lived in.

Counting properties changes the texture. The Environment Agency's rivers-and-sea mapping lists 3 of the village's postcodes as carrying any risk at all, covering 79 properties in total, of which 5 sit at high risk, 1 at medium and 4 at low, with one of the high-risk properties residential. Postcodes with no risk never appear in that list, so this is a portrait of the affected corner rather than of Sticker.

Across all 22 postcodes, the modelled flood extents put zero percent inside a high-risk extent with defences present in the model and zero percent inside a high-risk undefended extent. Nothing is being defended because nothing is modelled as needing it. Where the word defended does appear on maps like these, it means a defence exists in the model, not that the house behind it is dry.

Every one of the village's postcodes falls inside a shoreline management plan area even though the coast is roughly five kilometres away. The stated policy over the twenty-year and fifty-year horizons is managed realignment, letting the shoreline move in a controlled way, shifting to hold the line over the hundred-year horizon. A policy of that kind is an intention to manage, not a defence already standing and not a promise anyone has funded.

The nearest tide gauge, at Devonport, recorded sea level rising by about 2.35 millimetres a year across its record from 1962 to 2015. That is a measured historic rate rather than a projection, and at this distance inland it bears on the shoreline policy rather than on anyone's drains.

No historic flooding is recorded for any part of Sticker. That is genuinely reassuring, and it is not the same as proof that water has never come through a door here. National records capture what was reported and mapped, and a flooded garage in a bad winter does not always make the dataset.

Flood risk here lands in the middle: nothing from rivers or the sea, no history on file, and a small pocket of properties with a rating that a surveyor should be asked about by name. The village is dry. Which end of the slope your house sits on is the part worth checking.

Check it for your address. Flood risk can change from one street to the next, so look up the exact address on the government's long term flood risk service.
