Grondona, Apennine hills behind the Scrivia valley

Among the Apennine hills of the province of Alessandria, Grondona occupies a green, thinly populated side valley behind the Scrivia valley and the Novi Ligure area. The town hall stands at around 300 metres; all around are woods, meadows and scattered farmhouses, and the outlying hamlets climb towards the ridges.

For anyone working elsewhere, the reference point is the Scrivia valley and its roads, which lead towards Novi, Alessandria and Genoa. Buyers here are usually after a detached house with land or a rustic building to restore. In that case, check year-round car access, connection to mains water and sewerage, and the state of the roof before negotiating on price.

In 2023 there were 468 residents, down 14.1% on the 545 of 2011. The estimated average age is 52.7, against 48.9 for the province, and over-65s make up 31.8%. Foreign residents account for 4.3%. Declared incomes are in line with the provincial average.

For earthquakes, Grondona is in zone 3 of the national scale set by the Civil Protection Department, like 127 of the 187 municipalities in the province of Alessandria, with an expected ground acceleration of about 0.094 g. The hazard is moderate, but in a stone building it is still worth checking how walls and floors are tied together, especially if you are planning an extension.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Grondona, and the report links the address to its land parcel. In a narrow valley with a stream at the bottom and steep sides, flooding and landslides are checked spot by spot on the official maps.

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