Isola Sant'Antonio, lowland near the Po

Isola Sant'Antonio is a lowland municipality at the edge of the province of Alessandria, close to the Po, which here marks the border with Lombardy. The land is low and flat, with fields and farmsteads, and the village is a compact cluster from which you drive to the larger towns of the area for secondary schools, hospital care and work.

For a buyer, the closeness of the river is the first thing to understand. Along the Po the official maps mark flood hazard bands that vary a lot from one address to another: the report reads them for the exact position of the house on the official maps, together with the distance from the embankments and smaller watercourses. It is a check to make before an offer, not after.

In 2023 there were 653 residents, down 11.0% on the 734 of 2011. The average age is 48.9, the same as the province (48.9), and over-65s make up 30.9% of residents, against 28.6%. Foreign residents are 12.1%. Average declared income is below the provincial average.

Homes are mostly detached houses and courtyard houses, brick-built in the style of the Po plain. Rising damp, the roof and the systems are the most useful checks. Heating zone E means cold, foggy winters.

Isola Sant'Antonio is in seismic zone 3, like 127 of the 187 municipalities in the province, with an expected ground acceleration in the built-up area of about 0.064 g. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report traces the land parcel and the building from the address.

Earthquakes

For Italy's Civil Protection Department, Isola Sant'Antonio is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (127 of 187) are in the same zone.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
