Arco: what to know before buying a home

Overview

Arco is a municipality in the province of Trento, in Trentino-Alto Adige/Südtirol. At the end of 2023 it had 17,754 residents, among the most populous in the province (5 of 166).

Earthquakes

For Italy's Civil Protection Department, Arco is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (147 of 166) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.114 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.

Landslides and flooding

Landslide and flood risk changes from one street to the next, even within the same municipality: for this reason we do not summarise it as a single figure for the whole of Arco.

The report checks the exact address against the ISPRA national maps and tells you in plain words whether the building falls within an at-risk area. The official map is also available on IdroGEO.

House prices

We do not publish price tables by municipality. The report gives the minimum and maximum price per square metre for the address's zone, from the Revenue Agency's OMI valuations, with the reference half-year. It is a range for the zone, not the value of a specific home.

Population

Compared with the 2011 census, the resident population has grown by 5.2%. The estimated average age is 45 years, in line with the province. 23% of residents are over 65 (the regional figure is 22%). Foreign residents make up 8.5% of the population. On average, a household has 2.3 members.

Services

In the official Ministry of Education and Ministry of Health lists, Arco has 9 schools and 5 pharmacies. The Overture Maps data also lists 17 grocery shops and supermarkets, 10 healthcare facilities, 19 sports facilities and 11 parks and green areas.

There are 0.6 healthcare facilities per 1,000 residents, more than the province average (0.4).

This data is gathered from several providers: services may be missing or closed businesses may still appear. The report counts services within 500 metres and 1 kilometre of the address.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

Land registry

For Arco the Revenue Agency does not publish cadastral maps: the land registry here uses the tavolare (land book) system. The report cannot give a parcel reference, but it still checks risks, services and transport at the address and states this clearly.
