Casale sul Sile, on the river between Treviso and the lagoon
As the name says, Casale sits on the Sile, a spring-fed river that rises in the plain around Treviso and flows past the city towards the Venice lagoon. The town lies south-east of Treviso on flat land, and the river and its regional nature park shape part of the landscape: embankments, meanders, wet meadows and riverside paths used by walkers and cyclists.
It is a residential town for families who work in Treviso, in Mestre or at local firms and want a house with a garden within reasonable reach of both. Declared incomes are above the provincial average. The housing is mostly detached and semi-detached houses and small blocks of flats, with a few restored farmhouses near the river.
The population is young for Veneto. At the end of 2023 Istat, the national statistics office, counted 13,101 residents, up 3.0% on 2011. The estimated average age is 45.0 against 46.0 for the province of Treviso, and over-65s make up 20.5% against 23.8%. Foreign residents make up 4.6%.
The river is also the first thing to weigh up. The land is low, a few metres above sea level, the water table is close to the surface, and areas along the Sile and its tributaries can flood. The report checks the official flood maps for the address; in a house close to the water, also look for damp in the walls and ask whether the ground-floor rooms have ever flooded.
The province of Treviso has 4 municipalities in seismic zone 1 and 72 in zone 2, towards the hills and the Montello ridge. The low-lying south towards Venice is calmer: Casale is in zone 3, with an expected ground acceleration of about 0.107 g. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the plot from the address.
