For example: Via Zara 2, Ponte Lambro.

Ponte Lambro, on the river at the mouth of the Vallassina

The name gives it away: Ponte Lambro stands on the river Lambro, just above Erba, where the river leaves the Vallassina valley and heads down towards the plain. The town covers the valley floor and the slopes on either side, and is densely built for a municipality of its size.

For anyone working in Milan, the train is the strong point. The official timetables list 1 railway stop in the municipality, served by 1 line running down to Milan through Brianza, and the report shows how far it is from each address. Drivers go through Erba to reach Como and Lecco.

There were 4,248 residents in 2023, down 2.2% compared with 2011. The average age is 46.0, almost the same as the province (46.3), and over-65s make up 24.0%. Foreign residents make up 13.7%. Average declared incomes are below the Como average.

If you are buying near the river, water comes first. When the Lambro is in spate it can overflow in the low-lying stretches, while on the slopes the issues are landslides and rainwater run-off. The report checks the official flood and landslide maps for the exact address, not an average for the town.

Earthquakes are a minor concern: all 147 municipalities in the province of Como are in seismic zone 4, the lowest in the national classification, and the expected ground acceleration here is about 0.045 g. The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, so the address can be traced back to its plot.
