Understanding hazards in Draix
The assessment of industrial and natural hazards in Draix crosses several official public bases: ICPE (Géorisques DGPR), Seveso sites, flood plans (PPRI), seismicity (BRGM) and radon potential (IRSN). Each of these families is detailed, quantified and sourced in the indicators above.
In practice, the town has 0 ICPE on average (1 km radius), of which an unrecorded share at the commune level in Seveso sites with major industrial risk. No flood plan (PPRI) zone identified. The radon potential is not recorded for this town in the IRSN classification.
For a purchase, the State of Risks and Pollutions (ERP) is mandatory and must be appended to the sale agreement. It lists all natural disaster orders (CatNat), PPR zones, and known polluted sites. To request systematically, ideally before the offer.
Sources: Géorisques (DGPR) — ICPE, Seveso, PPRI, BASIAS/BASOL. BRGM — seismicity, clay shrink-swell. IRSN — radon potential. ERP mandatory at sale (Environment Code L.125-5). The overall score is an NTYP composite (weighting of the dimensions above) — see our methodology.
Clay shrink-swell (cracks)
In Draix, exposure to clay-soil shrink-swell is Exposition forte.
Clay shrink-swell (RGA) is the leading cause of cracks in single-family houses: clay soils swell when wet and shrink during drought, which moves foundations and cracks walls. The phenomenon is rising sharply as drought episodes multiply.
The damage is compensated under the natural disaster cover of home insurance, provided a "drought" CatNat order is issued for the town. Before buying on clay-rich ground, have the hazard and the state of the building checked (soil survey, existing cracks) — it is a point to verify systematically.

Frequently asked questions
How to know if my address is concerned by a flood plan (PPRI)?
The State of Risks and Pollutions (ERP) is mandatory at sale and rental. The seller or landlord must give it to you appended to the agreement. You can also check directly georisques.gouv.fr with your address.
Seveso site within 500 m: danger?
An upper-tier Seveso site has a PPRT binding on building permits. The lethal effect zone is typically < 500 m, the serious-injury zone < 2 km. At 500-2000 m, risks are monitored (SAIP alert) but existing buildings remain insurable.
High radon: what to do?
Radon is a radioactive gas of geological origin, present in granitic subsoil (Brittany, Massif Central, Vosges). For levels > 300 Bq/m³, IRSN recommendations: enhanced ventilation, slab sealing, continuous measurements. Intervention cost: 500-5000 €.
How does home insurance account for hazards?
Natural disasters are covered mandatorily (12 % contribution of the multi-risk contract). Clay shrink-swell (RGA) is rising rapidly (climate change) and some areas see insurance refusals or high deductibles. Compare several insurers before signing.
