Parcel 28396 000 ZD 73
Cadastral parcel of 807 m² (recorded area), in Trizay-lès-Bonneval.
- Recorded area
- 807 m²
- Planning zone
- No zone published
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
- Commune under the RNU: building is in principle limited to the already built-up parts of the commune; a certificat d’urbanisme says what is possible on this parcel. Guide: Use a planning certificate for the next step
- 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
- The computed area (992 m²) differs by 23% from the recorded area (807 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
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
Planning zoning
No PLU: the commune follows the national planning rules (RNU).

Local plan prescriptions
For guidance only, from the Géoportail de l'Urbanisme extraction of 15 August 2026; the linked document may have been replaced since. Only the planning document's regulations and annexes are binding. A missing item means “not recorded”, not “no constraint”.
National clay exposure (BRGM/Géorisques) and labels in the local planning document are separate sources: dates, methods and purposes may differ. Both values are retained; neither replaces the other. Check the national map and local rules with the authorities. Data versions: national clay layer 2026-07-02; GPU extraction 2026-08-15. Géorisques: soil studies and construction

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.
