Costanzana, a village among the Vercelli rice fields

Around Costanzana the Vercelli plain is flat and open, divided into rice paddies, canals and farm tracks. The village, just over 100 metres above sea level, is a small farming community, with a compact built-up core and a few farmsteads scattered across the fields. Vercelli and the larger towns of the province are reached by car for work and services.

Living among rice fields has practical sides worth knowing. Water stays in the fields for months, so damp on ground floors and in cellars is one of the first things to check; summer brings mosquitoes and winter brings fog. This is climate zone E, with cold winters, so insulation and the boiler matter. Farmsteads for sale can have huge amounts of space, but the cost of restoring and heating them grows accordingly.

The population is down 6.4% since 2011, with 764 residents in 2023. The average age is 50.5, against 48.4 in the province, and over-65s make up 31.0%, more than the provincial 28.0%. Foreign residents account for 5.8%. Average income is slightly below that of the province of Vercelli.

In seismic terms Costanzana is in zone 4, like 81 of the 82 municipalities in the province, with an expected ground acceleration of about 0.037 g, a very low hazard.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality, and the report links the address to the land parcel. On a plain crossed by canals and irrigation channels, flood hazard should be read from the official maps for the exact location of the house.

Key points

  • Small farming village on the Vercelli rice plain.

Overview

Costanzana is a municipality in the province of Vercelli, in Piemonte. At the end of 2023 it had 764 residents, ranked 38 of 82 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Costanzana is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (81 of 82) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.037 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.
