Carrega Ligure, scattered hamlets in the upper Val Borbera

The name is misleading: Carrega Ligure is in Piedmont, in the province of Alessandria, in the upper Val Borbera. It belongs to the Quattro Province area, the stretch of Apennines where the territories of Alessandria, Genoa, Pavia and Piacenza meet, and is made up of many small hamlets scattered among woods and ridges, at around nine hundred and fifty metres and higher.

For buyers, distance is the first thing to weigh up. Roads are long, narrow and winding, and for schools, doctors and shops you go down to the towns of the middle and lower valley. Houses are almost all of stone, many used as second homes or kept by families for the summer. Before an offer, check the roof, damp, services, utility connections and access in snow, since this is climate zone F.

The population is almost the same as in 2011: 82 residents in 2023, against 83, a variation of -1.2%. It is very old, though, with an estimated average age of 58.3 and over-65s at 43.9%, against 28.6% for the province. Declared incomes remain below the provincial average.

Carrega Ligure is in seismic zone 3, on the scale set by the Civil Protection Department, like 126 other municipalities in the province of Alessandria, and the expected ground acceleration is about 0.098 g. For a stone house, it matters how walls, floors and roof are tied together.

Between Apennine slopes and streams, conditions change from hamlet to hamlet: the report checks landslides and flooding on the official maps at the address and finds the land parcel with the Revenue Agency (Agenzia delle Entrate) cadastral maps.

Key points

Earthquakes

For Italy's Civil Protection Department, Carrega Ligure 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.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.098 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

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

The estimated average age is 58 years, higher than the province average (49). 44% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.2% of the population. On average, a household has 1.4 members.
