Radon: Vecoux is in France’s highest category
The state hasn’t mapped flood zones in Vecoux in detail, yet it has declared 6 flood disasters here since 1982, the last in November 2023. Hazard risk is not graded in France: there is no national flood map, so a town outside the mapped areas can’t be called safe from floods.

Why hazards aren’t graded in France
In the UK, the Hazard risk grade is the share of homes in a mapped flood zone; in the U.S., it is FEMA’s modelled yearly damage to buildings. Both rest on maps that cover the whole country. France maps flood zones in detail only in its 125 areas at highest risk (TRI), so most towns have no figure, and a blank would read as “dry”. The state’s disaster declarations don’t fill the gap: they depend on the mayor applying, and they don’t line up with the mapped zones. So Vecoux has no Hazard grade, and its overall grade uses the other six subjects.
Everything on this page is shown as published. We’ll grade it when France publishes a national flood map.

Vecoux is outside the state’s detailed flood maps, so no flood zone shows here; that doesn’t mean no flood risk (below). The map opens on the clay ground instead.
No detailed flood map for Vecoux
France maps flood zones in detail only in its areas at highest risk (TRI). Vecoux isn’t one, so there is no share of residents to show. That isn’t a clean bill of health: the state has declared 6 flood disasters here since 1982, the last in November 2023.
What the state does have for Vecoux: a flood risk plan (PPR), which maps the zones where building is restricted and a flood atlas (Moselle(Zones Inondées)) showing where past floods reached.

Declarations by hazard · 1982–2025
Each line is a state order recognizing a natural disaster in the commune (“CatNat”), which lets insured owners claim. The latest flood began November 12, 2023; 4 flood declarations since 1995.
This count partly reflects how often a mayor applies for a declaration, so it isn’t compared between towns. It is a record of recognized claims, not a flood map. Source: GASPAR, Géorisques, file of 5 October 2026 (orders published to January 2026).
The state lists 5 hazards for Vecoux
Risk plans in force or in preparation, and the prefecture’s list of major risks.
| Hazard | Risk plan (PPR) | Listed by the prefecture |
|---|---|---|
| River flooding and runoff | Approved 2008 | ✓ |
| Landslides and rockfalls | — | ✓ |
| Clay shrink-swell | — | ✓ |
| Earthquake | — | ✓ |
| Radon | — | ✓ |
A risk plan (plan de prévention des risques, PPR) is the state’s map of where building is banned or restricted because of a hazard; it is attached to the town’s planning rules, and a seller or landlord must tell you if the home is in one. The prefecture’s file of major risks (DDRM) lists the hazards it expects in each commune.

Earthquake zone 3 (moderate); 29% of residents on shrink-swell clay
What the ground under Vecoux does: national maps, the same for every town.
Residents on shrink-swell clay · share of residents
Clay ground swells when wet and shrinks in drought, which cracks walls of houses on shallow foundations. Since 2020, a soil study is required before selling a building plot in a medium or high zone. 0 drought (clay) declarations here since 1982.
Vecoux is in zone 3 (moderate). New buildings must follow the earthquake building code (Eurocode 8) for their type. The zone sets building rules; it isn’t a forecast.

Radon potential in Vecoux: category 3 of 3 (significant)
Radon is a natural radioactive gas from granite and volcanic rock; it builds up indoors.
Vecoux is in category 3: parts of the ground can release significant radon. Since 2018, sellers and landlords here must mention it, and testing a home over two winter months is advised.
The category describes the rocks under the commune, not any home: a test is the only way to know.

No industrial risk plan reaches Vecoux
Hazardous sites whose danger zone reaches the town, and the technological risks the prefecture lists.
Seveso sites store or use large amounts of dangerous substances; upper-tier sites have a risk plan around them. Distances are from the town’s center.

Being ready in Vecoux
Where France publishes warnings, and what to ask before you buy or rent.
- Météo-France’s vigilance map gives the day’s warnings by département, from yellow to red.
- Vigicrues shows river levels and flood warnings for the main rivers, updated twice a day.
- FR-Alert sends emergency alerts to every phone in the area; no sign-up needed.
- The seller or landlord must give you a risk statement (état des risques) for the address, listing the plans it is in.
- They must also tell you about any natural-disaster claim paid on the home.
- Géorisques gives the same statement for any address, free.
- Test over at least two months between September and April.
- Above 300 Bq/m³, air the home and seal the floor.
- Ask for the risk statement and read which plans the address is in.
- Ask the town hall for its risk booklet (DICRIM) and safety plan (PCS).
- For a house, look for cracks and ask about the foundations: much of the town is on shrink-swell clay.
- Check that home insurance includes natural-disaster cover (it comes with fire cover).
What this data can and can’t tell you
- Not graded. France has no national flood map, so we don’t grade hazard risk. Comparisons on this page are with other French towns of 2,500+, shown for context.
- Mapped areas only. Flood shares exist only where the state has mapped flooding in detail (the TRI areas). A town without a figure has no map, not no risk.
- Disaster declarations. A CatNat order recognizes a disaster so that insurers pay; it follows the commune’s application. The count partly reflects how often a mayor applies, so we show it but don’t compare towns on it.
- Plans. A risk plan maps where building is limited; it doesn’t say any one home will flood.
- Clay, earthquakes, radon. National maps of the ground: they describe susceptibility and set building rules, not damage or forecasts.
