Staranzano, between Monfalcone and the Isonzo estuary

Staranzano borders Monfalcone and reaches the sea where the Isonzo flows into the Gulf of Trieste. The town is in the Bisiacaria, the low plain between the Karst plateau and the river, and much of its land towards the coast lies within the Foce dell'Isonzo nature reserve, including the Isola della Cona, popular with birdwatchers. The centre stands a few metres above sea level, surrounded by fields, canals and residential streets.

Being next to Monfalcone shapes much of local life. The shipyard and the area's industries employ many residents, and Trieste airport, at Ronchi dei Legionari, is a few minutes' drive away. The housing is mainly detached houses and villas, in a quieter setting than the neighbouring town. Declared incomes are above the provincial average, and there are 5 green spaces recorded, more per head than the provincial average.

At the end of 2023 there were 7,148 residents according to Istat, the national statistics office, almost the same as in 2011 (down 0.7%). The average age is 47.6, slightly below the Gorizia area, and over-65s make up 26.1%. Foreign residents account for 7.0%.

As elsewhere in the former Austrian lands, the tavolare system applies here: ownership passes when it is entered in the land register (libro fondiario), so before buying it is worth reading the register extract to check owners, mortgages and easements. The Revenue Agency (Agenzia delle Entrate) still publishes cadastral maps, and the report traces the address back to its plot.

Staranzano is in seismic zone 3 on the Civil Protection scale, like 14 other municipalities in the province, with an expected ground acceleration of about 0.131 g. On a plain this low, between river, drainage canals and sea, water matters more: flood hazard varies a lot between areas near the coast or the Isonzo and the rest of town, and the report checks the official maps for the address. Damp in walls and ground floors is also worth checking on a viewing.

Key points

  • 7,148 residents on the plain between Monfalcone and the Isonzo mouth.
  • Tavolare land register: read the register extract.
  • Seismic zone 3, expected acceleration about 0.131 g.
  • Check flooding and damp near the coast and river.

Overview

Staranzano is a municipality in the province of Gorizia, in Friuli-Venezia Giulia. At the end of 2023 it had 7,148 residents, ranked 6 of 25 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Staranzano is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (15 of 25) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.131 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.

Population

Compared with the 2011 census, the number of residents is nearly unchanged. The estimated average age is 48 years, in line with the province. 26% of residents are over 65 (the regional figure is 27%). Foreign residents make up 7.0% of the population. On average, a household has 2.2 members.

Income and climate

In tax year 2024, taxpayers in Staranzano declared an average taxable income of 26,284 euros, above the provincial average (24,418 euros). The Italian average is 24,895 euros.

Staranzano is in climate zone E, with 2,246 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 6 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Staranzano has 5 schools and 2 pharmacies. The Overture Maps data also lists 1 grocery shop, 2 healthcare facilities, 5 sports facilities and 5 parks and green areas.

There are 0.1 grocery shops and supermarkets per 1,000 residents, fewer than the province average (0.5).

Public transport

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

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 12.3% of the land in Staranzano, compared with 13.0% in the province and 8.1% in the region. In 2024 built-up land grew by 0.5 hectares.

Radon and contaminated sites

Staranzano is not among the radon priority areas designated by the Regione Friuli Venezia Giulia in 2024. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Staranzano, and 2 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Staranzano: 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.

Land registry

Staranzano uses the tavolare (land book) system, but the Revenue Agency still publishes the maps: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.

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 29 inhabited census areas in Staranzano. Half of the residents live in areas scoring 69 or more.
