Trenzano, farmland between Brescia and Chiari

In the countryside between Brescia and Chiari, west of the provincial capital, Trenzano has Rovato and the Franciacorta wine area a little further north. The landscape is the irrigated plain: maize fields, channels, farmsteads and a compact village centre, extended over the years with estates of small villas and terraced houses.

People who move here almost always work elsewhere, in Brescia or in the industrial areas nearby, and they drive: the public transport data show 0 stops in the municipality. Everyday services are available, but for more people rely on nearby towns. There are, for example, 6 places to eat and drink, far fewer per head than the provincial average. Average declared incomes are below those of the province.

The population has barely changed, 5,512 residents in 2023 against 5,480 in 2011 according to Istat, the national statistics office, but it is young. The average age is 43.4, below the province's 45.4; over-65s make up 20.0%, and households average 2.62 people, a high figure. Foreign residents are 10.9%. The data list 4 healthcare facilities and 2 pharmacies.

Seismic risk varies a lot across the province of Brescia: 52 municipalities are in zone 2 on the Civil Protection Department's scale, the rest in zone 3. Trenzano is in zone 3, but with expected ground acceleration of about 0.137 g, not a low value for the plain. If you are buying a house from the 1960s or 1970s or a converted farmstead, ask for the structural design and details of any work done.

Channels and spring-fed ditches cross the fields, and in places the water table is close to the surface. The report checks the flood maps at the address and traces the plot on the Revenue Agency's maps.
