The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 172 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.

What this means for a project

Zone UDi: 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
Zone UD: 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
The parcel is split between 2 zones: each part follows the rules of its own zone. Guide: Read the documents, not just the colour
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
PPRi Débordement de la rivière Marne pour les communes du secteur amont de la CAC covers 72% of the parcel: its rules may forbid or restrict building; read them before any project. Guide: Identify the scope of each finding

Buildings

Indicative data (IGN BD TOPO): buildings IGN links to the parcel (BAN PLUS) when they cover at least 20 m² of it, with information from the tax files (DGFiP), anonymised. An unknown height or number is not shown. Construction years are grouped into periods, because old buildings often carry an estimated round year (1800, 1900…). A building standing on several parcels is counted on each, with all its dwellings. Recent buildings may be missing: the tax files are updated with a delay.

On the parcel: 2 buildings
Use: Residential
Height to the eaves: up to 3.3 m
Storeys: up to 1 (ground floor included)
Dwellings: 1
Built: 1900 or earlier

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: Low exposure (100% of the parcel)
Risk prevention plan: Natural or mining risk plan (PM1) – PPRi Débordement de la rivière Marne pour les communes du secteur amont de la CAC – 72% of the parcel
Seismic zone: Zone 1 (very low)
Radon potential: Category 1 (low)
