Parcel 91691 000 AE 790

Cadastral parcel of 22 m² (recorded area), in Yerres. Planning document zoning: urban zone (UA).

Recorded area: 22 m²
Planning zone: UAUrban zone (U)

The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 24 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)

What this means for a project

Zone UA: 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
3 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: High 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 (28 m²) differs by 26% from the recorded area (22 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

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

Marshes, peat bogs and wetlands to preserve: Le terrain est situé dans un secteur de milieux humide - Zone humide probable. – 100% of the parcel
Protected shop frontage: Le terrain est concerné par un linéaire commercial à protéger. – line on the parcel or its boundary

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 1 (very low)
Radon potential: Category 1 (low)
