Sardigliano, hamlets in the hills near Tortona

Sardigliano is a hill municipality in the Tortona area, a short way from the Scrivia valley. The land is made up of low ridges, woods and fields, with the main village at around 260 metres and several scattered hamlets. Novi Ligure and Tortona are the towns people go to for work, secondary school and the big weekly shop, and from there the motorways run to Genoa and Milan.

Buyers here are usually after a country or village house with some land. With an isolated farmhouse, check access, the mains water supply and drainage, as well as the state of the roof. On the slopes of these hills landslide hazard has to be looked at plot by plot: the report reads it from the official maps at the address.

The village has lost residents since 2011: 374 in 2023 against 452, a fall of 17.3%, according to Istat, the national statistics office. The estimated average age is 50.7, against 48.9 for the province of Alessandria, and over-65s make up 31.8%. Declared incomes are a little above the provincial average.

The municipality is in seismic zone 3 on the Civil Protection Department's scale, along with 126 other municipalities in the province; the remaining 60 are in zone 4. Expected ground acceleration in the built-up area is about 0.094 g, a moderate value: for an old masonry house it is worth knowing whether any work has been done on the roof and floors.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Sardigliano, and the report traces the address back to the land parcel.

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

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 13 inhabited census areas in Sardigliano. Half of the residents live in areas scoring 58 or more.
