Castelletto Cervo, Biella lowlands along the Cervo

The Cervo stream comes down from the mountains above Biella and, before joining the Sesia, crosses the plain in the south of the province: Castelletto Cervo is here, at about 200 metres, in a flat landscape of rice paddies, fields and woodland along the watercourse, close to the boundary with the province of Vercelli.

The village is agricultural and residential, with village houses, farmsteads and detached houses. For work and services people look to Biella, Vercelli and the towns of the plain, all reached by car. If you are buying a farmhouse or an old house, estimate early on the cost of the roof, rising damp and the systems, and allow for the cold, foggy winters of climate zone E.

Being close to the Cervo is the point to check most carefully: the official flood maps are read address by address, and the report does this automatically, along with data on altitude and slope.

At the end of 2023 there were 788 residents, down 10.5% from the 880 of 2011. The village is younger than the provincial average: an average age of 47.4 against 49.7, with over-65s at 24.1% against 30.1%. Foreign residents make up 6.6%. Average declared income is below the provincial figure.

Castelletto Cervo is in seismic zone 4, the lowest, like 49 other municipalities in the province, and the expected ground acceleration is about 0.039 g. Earthquakes matter little here; foundations and damp on ground close to water matter more.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report links the address to its land parcel and building.

Overview

Castelletto Cervo is a municipality in the province of Biella, in Piemonte. At the end of 2023 it had 788 residents, ranked 47 of 74 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Castelletto Cervo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (50 of 74) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.039 g, a low value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
