San Biagio di Callalta, villages between Treviso and the Piave
San Biagio di Callalta stretches across the plain east of Treviso, along the old Postumia road, as far as the banks of the Piave. It is a municipality of separate villages: besides the main one there are places such as Olmi, Spercenigo and Fagarè della Battaglia, where a military memorial honours those who died in the First World War battles fought along the river.
Treviso is about ten kilometres away, and many residents work in the city or in the business parks along the Postumia. Most homes are detached or semi-detached houses, or small blocks of flats with gardens, often built by the families themselves in recent decades. With services split between villages, check what is really close to an address: the data show 3 sports facilities and 1 healthcare sites, few for the population, while schools are well spread, 1.10 per 1,000 residents against 0.86.
There were 12,705 residents at the end of 2023, down 2.6% since 2011. The average age is 45.8, practically the same as the province, and foreign residents make up 10.5%. Average declared incomes are a little below the provincial figure.
Earthquakes matter even on the plain. The province of Treviso is among the most exposed in Veneto: 72 municipalities are in seismic zone 2 and 4 in zone 1, towards the hills and the Pre-Alps. San Biagio is one of the 18 in zone 3 on the Civil Protection map, with expected ground acceleration of 0.130 g. It is still worth asking when a building was put up and how its structure is made.
The Piave and the smaller watercourses crossing the countryside are what to check for flooding, especially in the villages nearest the river. The report reads the official flood hazard maps for the exact address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so the report finds the land parcel.
