Click a parcel: boundaries, risks, OMI prices.

1. Take the sheet (foglio) and parcel (particella) numbers from the cadastral record or the deed (if you do not have them: search by person, €4.90). E.g. «Fg. 4 part. 102»: sheet 4, parcel 102. If you only have the address, start from that.
2. Type them in the box below, or open them on the cadastral map of Bionaz, where you pick the sheet from the list of those that exist.
3. Click the parcel for its boundary, area, OMI price ranges for the zone, seismic zone and constraints. For land where you only know the position, the boundaries can be read from the point.

The cadastral map is the official one from the Agenzia delle Entrate (Italian Revenue Agency). For a document with legal value you need the visura catastale (cadastral record, €4.90): the data on this page is for orientation.

Each number opens the map framed on that sheet.
