Colazza, wooded hills not far from Lake Maggiore

Among the wooded hills in the north of the province of Novara, a short way from Lake Maggiore, Colazza is a small, quiet village with its town hall at around 500 metres and houses scattered among meadows and woodland. The lake and its resorts are a short drive away, as are the roads towards Novara and Milan.

Colazza is growing. In 2023 there were 541 residents against 463 in 2011: 78 more, a rise of 16.8%. The average age is 48.5 against 46.7 in the province, over-65s make up 28.1% and households have 1.84 people on average. Declared incomes are close to the provincial average.

Homes are mostly detached houses with gardens, alongside a few older buildings in the village core. People arriving from the city find space and greenery; in return they depend on the car for nearly everything and have land to look after. The climate zone is E, and winters in the hills are damp.

All 87 municipalities in the province of Novara are in seismic zone 4, the lowest class, and in Colazza the expected ground acceleration in the village is about 0.040 g. Earthquakes count for little in the choice here: aspect, damp and the state of the services matter more.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report links the address to its parcel. On sloping land it is worth checking the gradient and landslide hazard of the plot, which the report reads on the official maps.

Key points

  • Wooded hills in the province of Novara, near Lake Maggiore.

Overview

Colazza is a municipality in the province of Novara, in Piemonte. At the end of 2023 it had 541 residents, among the smallest in the province (81 of 87).

Earthquakes

For Italy's Civil Protection Department, Colazza is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.040 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.

Population

Compared with the 2011 census, the resident population has grown by 16.8%. The estimated average age is 49 years, higher than the province average (47). 28% of residents are over 65 (the regional figure is 27%). Foreign residents make up 7.2% of the population. On average, a household has 1.8 members.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Colazza: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 5 inhabited census areas in Colazza. Half of the residents live in areas scoring 66 or more.
