Gazzaniga, the Serio valley floor and the hamlet of Orezzo

Gazzaniga lies in the middle Val Seriana, on the floor of the Serio valley between Fiorano al Serio and Vertova. Like most of the valley it grew with industry, textiles above all, and it still looks the part: houses and factories squeezed between the river and the slopes, with post-war blocks of flats next to the old core. Higher up, on the mountainside, is the hamlet of Orezzo.

The link to Bergamo is the valley's provincial road, which slows down a good deal at rush hour. The Valli tram line runs as far as Albino, a few kilometres down the valley, and from there into the city without traffic; for many commuters it is the easiest option. Buyers will find flats in the valley floor, older houses in the centre and homes with land on the slopes and in Orezzo, where winter road conditions need to be taken into account.

The population is ageing and shrinking. In 2023 there were 4,923 residents, down 4.6% on 2011; the average age is 47.4 against 45.2 in the province, and people over 65 make up 27.0%, well above the provincial 22.5%. Foreign residents account for 9.1%. Declared incomes are below the provincial average.

All 243 municipalities in the province of Bergamo are in seismic zone 3, and the expected ground acceleration here is about 0.106 g. The hazard is moderate; in blocks from the 1960s and 1970s, insulation and running costs also matter in a climate as cold as the valley's.

The valley is narrow, and the Serio and its side streams can rise quickly in heavy rain; on the steep slopes landslide hazard also has to be considered. The report checks both at the address and uses the Revenue Agency (Agenzia delle Entrate) cadastral maps.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
