San Giacomo delle Segnate, the low plain south of the Po
San Giacomo delle Segnate lies in the Oltrepò Mantovano, the plain south of the river Po on the border with Emilia, in flat countryside of fields, drainage canals and rows of trees. The village is only a few metres above sea level. Mantua and the nearby towns of Emilia are the reference for work and services, and journeys are made by car.
On such low ground, water is the first thing to look at. The canal network keeps the fields dry, but flood hazard varies from one spot to the next: the report checks the official maps for the exact address. In brick country houses, check rising damp, cellars and roofs, and for houses extended over the years, the building permits.
Istat, the national statistics office, counted 1,514 residents in 2023, down 14.9% on the 1,779 of 2011. The village is older than its province: an average age of 49.4 against 46.4, and over-65s at 29.3% against 24.4%. Foreign residents account for 14.5%. Declared incomes are below the provincial average.
On earthquakes, the province of Mantua has 5 municipalities in zone 2 and 59 in zone 3. San Giacomo is in zone 3, with an expected ground acceleration of about 0.110 g. In an older building, have the connections between walls and floors, chimneys and cornices checked, and ask what structural work has been done.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report finds the land parcel from the address.
