The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.
For example: Via Longarola 1, Calderara di Reno.
Calderara di Reno, next door to Bologna airport
Calderara di Reno borders Bologna to the north-west and runs right up to the runways of Marconi airport. It is a lowland municipality along the Reno river, made up of the main town and villages such as Longara and Lippo, with the Bargellino business area right next to the airport. For anyone working in Bologna the distance is short, and the ring road is a few minutes away.
Aircraft noise has to be judged street by street: some areas lie under the take-off and landing paths, others are clear of them. That is the first thing to check before a viewing, together with how close the house is to main roads and warehouses.
There were 13,690 residents in 2023, up 4.1% since 2011 according to Istat, the national statistics office. The estimated mean age of 46.3 is close to the provincial figure, and over-65s are 24.2%. Households are small, 2.19 people on average, and foreign residents are 10.3%. Declared incomes are slightly below the average for the province of Bologna, which is high.
Calderara is in seismic zone 3 of the Civil Protection classification, like 43 municipalities in the province, but the expected ground acceleration in the built-up area, about 0.166 g, is not negligible. The 2012 earthquake struck the Emilian plain further north and showed how fragile some prefabricated industrial sheds and unreinforced masonry houses can be, so ask when the building was built and what work has been done on it.
The Reno flows between high embankments, in places above the level of the surrounding fields. For properties near the river and the canals, the report checks the official flood hazard maps at the exact address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the parcel leads to the building.

Earthquakes
For Italy's Civil Protection Department, Calderara di Reno is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (43 of 55) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.166 g, a medium-high 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.
Population
Compared with the 2011 census, the resident population has grown by 4.1%. The estimated average age is 46 years, in line with the province. 24% of residents are over 65 (the regional figure is 25%). Foreign residents make up 10.3% of the population. On average, a household has 2.2 members.
