Suisio, in the Isola between the Adda and the Brembo

The Isola bergamasca, literally the Bergamo island, is the triangle of plain and low hills enclosed by the Adda and Brembo rivers west of Bergamo, and Suisio lies inside it. The area is heavily built up, with sheds, workshops and villages that almost run into each other: in this municipality more than a quarter of the land is covered by buildings and roads. Residents often work for local firms, in Bergamo or towards Brianza and Milan.

The housing stock is mostly detached and terraced houses and small blocks of flats from recent decades, with a few older courtyard houses in the centre. When buying, what counts most is the position relative to through roads and industrial areas, since traffic and noise change from one street to the next.

In 2023 there were 3,775 residents, down 2.5% since 2011 according to Istat, the national statistics office. The population is a little younger than average: an average age of 44.7 against 45.2 in the province of Bergamo, with over-65s at 21.4%. Foreign residents make up 10.7%. Average declared incomes are below the provincial level.

All 243 municipalities in the province are in seismic zone 3 of the Civil Protection classification, and in Suisio the expected ground acceleration in the built-up area is about 0.084 g. The hazard is moderate, but for houses built before the current rules it helps to know the design date and any structural work carried out. Climate zone E means cold, damp winters.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report reaches the land parcel from the address. With irrigation channels, streams and small drops in level, closeness to a watercourse and the flood maps are read at the exact spot.
