Parcel 91200 000 AM 451

Dourdan (91200), section AM

Recorded area: 283 m²
PLU zone: NNatural and forest zone (N)

The parcel (coloured) and its neighbours, from the cadastre.

The cadastre is a tax record: it does not prove ownership. Why?

The cadastre is a tax record: it does not prove ownership and its boundaries have no legal force (only a surveyor's boundary marking does). Its plan is approximate: especially where it is old, it can be offset by a few metres from the buildings and the aerial imagery. The owner's name is not shown. Boundary marking (Service Public, in French)

Risks

This information is for guidance only and has no regulatory force: it does not replace the risk statement (état des risques, ERRIAL) to be attached to a sale or a rental, which anyone can produce free of charge on Géorisques.

Some clay soils swell when wet and shrink as they dry, which can crack buildings. The higher the exposure, the more building precautions are needed. A risk prevention plan (PPR) maps the areas exposed to a hazard (flooding, ground movement, an industrial site…) and sets building rules there. The Géoportail de l'Urbanisme does not list every plan yet.

Clay shrink-swell: Medium exposure (100% of the parcel)
Risk prevention plan: Natural or mining risk plan (PM1) – Plan de prevention des risques d'inondation dans la vallee de l'Orge et de la Sallemouille – 85% of the parcel
Seismic zone: Zone 1 (very low)
Radon potential: Category 1 (low)
