Calto, reclaimed plain in the Alto Polesine
Low land, embankments and drainage canals: Calto lies in the Alto Polesine, the western part of the province of Rovigo, on the plain enclosed by the rivers Po and Adige. The village is only a few metres above sea level, surrounded by open countryside where the horizon is flat in every direction. For services, secondary schools and work, people drive to the nearby towns and to Rovigo.
In land like this, water is the first issue. The Polesine plain was reclaimed from marshes over centuries and depends on a network of embankments, canals and pumping stations. The report checks the address against the official flood maps and shows the ground elevation: two houses in the same village can be in quite different positions. Homes are almost all detached, with a yard or garden.
In 2023 there were 683 residents, 136 fewer than the 819 of 2011 (down 16.6%). The estimated average age is 50.5, against 49.0 for the province, and over-65s are 31.9% against 28.1% provincially. Foreign residents make up 13.9%, and households average 2.25 people. Average declared income is close to the provincial figure.
All 50 municipalities in the province of Rovigo are in seismic zone 3 of the Civil Protection classification; in Calto expected acceleration is about 0.097 g. On soft plain soils it is also worth asking about the foundations and any cracks in the walls, and having a surveyor check whether repairs have been made.
The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report traces the address back to the plot.

Earthquakes
For Italy's Civil Protection Department, Calto is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 50 municipalities in the province are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.097 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 51 years, higher than the province average (49). 32% of residents are over 65 (the regional figure is 24%). Foreign residents make up 13.9% of the population. On average, a household has 2.2 members.
