Siapiccia, on the edge of the Oristano plain

A few kilometres of farmland separate Siapiccia from the Oristano plain: the village lies where the flat land starts rising towards the inland hills, at low altitude, with olive groves, pasture and fields around it. It is a small place, with one- and two-storey houses along a few streets. Oristano is the reference town for work, secondary schools, hospitals and trains, and is a short drive away.

Houses for sale are mostly village homes, some with a courtyard, often built in stages. Before buying, check that extensions are properly authorised, and look at the roof, damp and the wiring and plumbing. The climate zone is C, with mild winters: summer heat is the bigger issue here, and good insulation helps with that too. Near the watercourses running down to the plain, the report reads the official flood maps at the exact address.

In 2023 there were 350 residents, down 5.4% on the 370 of 2011, according to Istat, the national statistics office. The estimated average age of 48.7 is slightly below the 49.8 of the province of Oristano, and over-65s make up 28.9%, against 29.5%. Households average 2.32 people. Declared incomes are below the provincial average.

The earthquake picture is simple: all 87 municipalities in the province of Oristano are in seismic zone 4, the lowest on the national scale set by the Civil Protection Department, and expected ground acceleration in the built-up area is about 0.050 g. The focus is on routine upkeep.

The Revenue Agency (Agenzia delle Entrate) publishes Siapiccia's cadastral maps, so the report traces the address to its land parcel.

Overview

Siapiccia is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 350 residents, ranked 64 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Siapiccia is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 5.4%. The estimated average age is 49 years, in line with the province. 29% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.6% of the population. On average, a household has 2.3 members.

Radon and contaminated sites

Siapiccia is not among the radon priority areas designated by the Regione Sardegna in 2022. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Siapiccia: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

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 3 inhabited census areas in Siapiccia. Half of the residents live in areas scoring 66 or more.
