Osio Sotto, between Dalmine, Zingonia and the Brembo

Part of Zingonia, the new town built in the 1960s and split between five municipalities, lies within Osio Sotto. The village itself is on the plain south of Bergamo, not far from the river Brembo, between Dalmine, Levate and Verdellino, in an area where housing, industrial buildings and main roads follow one another without a break.

It is a town of commuters and businesses. The Dalmine junction on the A4 motorway is close and Bergamo is a short drive away. There is no station in the village (0 stops in Trenord's regional rail data), so train users go to Verdello-Dalmine, on the line to Treviglio. Housing ranges from 1970s and 1980s homes to newer detached houses and flats on the edges. Buyers should look at the distance from industrial areas and from roads used by heavy lorries.

The population is growing: 12,702 residents at the end of 2023, up 5.1% since 2011. People over 65 make up 21.1%, fewer than the provincial 22.5%, and foreign residents 12.6%. Average declared incomes are close to the provincial figure, slightly below. There are only 4 education sites, 0.31 per 1,000 residents against 0.87 in the province, while healthcare sites are above average.

All 243 municipalities in the province of Bergamo are in seismic zone 3 on the Civil Protection map. In Osio Sotto expected ground acceleration is 0.104 g, a moderate hazard. For a flat, ask when the building was designed and what state the shared parts are in, from roof to façade.

The Brembo runs in a valley cut below the level of the plain. Near the river and the irrigation canals, the report checks the official flood maps for the exact address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so the report finds the land parcel.
