Parcel 42289 000 AE 479
Cadastral parcel of 4,976 m² (recorded area), in Saint-Symphorien-de-Lay. Planning document zoning: urban zone (UC).

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.

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
- 4 prescriptions, information areas or easements touch the parcel (details below): they apply on top of the zone’s rules. Guide: Read the documents, not just the colour
- Clay soils: Medium exposure (100% of the parcel). General rule in medium or high exposure areas: the seller of unbuilt buildable land supplies a preliminary geotechnical study where planning rules permit individual houses. Exposure alone does not establish that this sale is covered. Construction projects are subject to separate rules to check with the professional. Géorisques: soil studies and construction
- Plan de Prévention des Risques Naturels Prévisibles d'inondation (PPRNPI) covers 100% of the parcel: its rules may forbid or restrict building; read them before any project. Guide: Identify the scope of each finding
- Radon potential category 3: it appears in the information given to buyers and tenants; ventilating and, during works, sealing between the ground and the building reduce exposure. Guide: Prepare the formal risk statement
Points drawn from this parcel’s data. They tell you which questions to ask; they do not replace a certificat d’urbanisme or the official statement of risks.
Understanding the map information
- French planning: who decides what
- The public data behind the map
- Reading and finding a cadastral reference
- Cadastre and boundary surveys: where does the land end?
- Reading a PLU: a zone label does not define a project
- Recorded and calculated parcel area: why two figures?
- Addresses and parcels: why they do not always match
- Parcel owners: what the map does not show and where to ask
- Dividing a plot: preparing a land division
- Property risks: from a map finding to a proper check

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.
