Coli, woods and hamlets above the Trebbia valley

Coli lies in the Apennines of the province of Piacenza, on the Trebbia valley side, in an area of woods, meadows and small hamlets spread along the valley of the Perino stream, which joins the Trebbia further down. The town hall stands at around 640 metres and the climate zone is F, the Italian category for long, cold winters, so snow is nothing unusual. Bobbio is the place people go to for services, while Piacenza is at the bottom of the valley.

Most homes on the market are stone buildings in the hamlets, often in need of work. Before making an offer, find out how the house is reached in winter, how it is heated, what state the roof is in and whether water, power and drainage are connected to the mains.

Istat, the national statistics office, counted 843 residents at the end of 2023, 112 fewer than in 2011, a fall of 11.7%. The average age is 54.0, against 46.7 for the province, and over-65s make up 38.2% of residents. Households are small, with 1.66 people on average.

All 46 municipalities in the province of Piacenza are in seismic zone 3 of the classification kept by the Civil Protection Department. In Coli the expected ground acceleration in the built-up area is about 0.104 g. In a stone house the weak points are usually the ties between walls and floors, and the roof, especially where the building was extended in several stages.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report works from the address to the land parcel. On the slopes of an Apennine valley, gradient and landslide hazard change from plot to plot: the official maps need reading at the exact spot, not for the municipality as a whole.

Key points

  • Mountain village in the Trebbia valley, hamlets along the Perino stream.
  • Population down 11.7% since 2011, average age 54.0.

Overview

Earthquakes

For Italy's Civil Protection Department, Coli is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 46 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.104 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 54 years, higher than the province average (47). 38% of residents are over 65 (the regional figure is 25%). Foreign residents make up 7.4% of the population.

Radon and contaminated sites

Coli is not among the radon priority areas designated by the Regione Emilia-Romagna in 2026. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Coli. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Coli: 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.

Land registry

The cadastral maps for Coli are public: from the address the report finds the sheet and parcel number.

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 64 inhabited census areas in Coli. Half of the residents live in areas scoring 57 or more.
