Riano, tuff rock and new districts north of Rome

In recent years Riano has taken in many families moving out of Rome to the north. The old village sits on a spur of tuff, the soft volcanic stone found across the countryside north of the capital, and around it districts of detached houses and small apartment blocks have grown up, some a fair way from the centre and linked only by provincial roads.

The growth shows in the figures from Istat, the national statistics office. There are 10,417 residents, up 9.2% on 2011, or 881 more people. The average age is 44.2 against 46.0 for the metropolitan area, and 19.7% are over 65. Foreign residents make up 16.9%, a high share. Declared incomes are below the average for the metropolitan area, which includes Rome itself.

For a buyer, the key question is the journey into Rome, on the old consular roads, the Via Flaminia and the Via Tiberina, with commuter traffic at peak times. Try the route at working hours before you decide. In the newer districts it is also worth checking that the house complies with planning rules and that sewers and services are in place, because in parts of the Roman countryside they arrived after the houses.

On tuff, the walls of ravines and embankments can collapse, and streams in the valleys swell during storms. The report checks the official landslide and flood maps for the address and measures the slope of the ground. The climate is zone D, with fairly mild winters.

The seismic hazard is moderate. Most municipalities in the metropolitan area, 97 of them, are in zone 2; Riano is among those in zone 3, along with 23 others, with an expected ground acceleration of about 0.100 g. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps.

Earthquakes

For Italy's Civil Protection Department, Riano is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Only 24 of 121 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.100 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

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 55 inhabited census areas in Riano. Half of the residents live in areas scoring 65 or more.
