Parcel 17337 000 AL 309

Cadastral parcel of 141 m² (recorded area), in Saint-Georges-d'Oléron. Local plan (PLU) zoning: urban zone (Uc).

Recorded area: 141 m²
PLU zone: UcUrban zone (U)

The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 80 m. North is up; the bar gives the scale.

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)

This parcel’s figures, from the cadastre, the national address base (BAN), IGN’s BD TOPO and the risk databases. Missing data is not shown.

What this means for a project

Zone Uc: before an extension, a shed or a division, read this zone’s rules (height, footprint, setbacks from the street and the boundaries). Guide: Turn the map finding into a specific question
1 prescription, information area or easement touches the parcel (details below): it applies on top of the zone’s rules. Guide: Read the documents, not just the colour
Clay soils: High exposure (100% of the parcel). With medium or high exposure, selling a building plot requires a preliminary soil survey, and a new house must follow adapted building rules. Guide: Prepare the formal risk statement
Seismic zone 3 (moderate): a new house must follow the earthquake-resistant building rules. Guide: Identify the scope of each finding
The computed area (123 m²) differs by 13% from the recorded area (141 m²): for a decision on the size or a boundary, only a chartered surveyor (géomètre-expert) is authoritative. Guide: Read a difference without choosing a figure arbitrarily

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: High exposure (100% of the parcel)
Risk prevention plan: Not recorded in the Géoportail de l'Urbanisme
Seismic zone: Zone 3 (moderate)
Radon potential: Category 1 (low)
