Cerro al Lambro, farmland and river south-east of Milan
The Lambro river gives the municipality its name and runs right through it. Cerro al Lambro lies in the plain south-east of Milan, just downstream of Melegnano, with two built-up areas, Cerro and Riozzo, surrounded by fields and old farmsteads.
For anyone working in Milan, location is the main draw. The Via Emilia and the A1 motorway pass close by, and suburban trains run from stations in neighbouring towns such as Melegnano; the report measures how far the most convenient stop is from the address. The housing stock is mostly detached and terraced houses and low blocks of flats built from the 1970s onwards, with gardens and garages, plus a few converted farm buildings. For bars and restaurants people often head out of town: there are 9, or 1.74 per 1,000 residents against 4.39 across the metropolitan area. Sports facilities, on the other hand, number 7, or 1.35 per 1,000 residents against 0.79.
The population is growing. Istat, the national statistics office, recorded 5,184 residents in 2023, up 4.6% on 2011. The average age is 45.8, close to the provincial figure, and 24.3% are over 65 against 23.0%. Foreign residents make up 6.1%. Average income is below that of the Milan metropolitan area, which is among the highest in Italy.
Seismic hazard is low. Cerro is in zone 3 of the Civil Protection classification, along with 59 other municipalities around Milan, while the rest are in zone 4, and the expected ground acceleration is about 0.061 g. In a fifty-year-old house, insulation, windows and heating matter far more.
The river deserves attention. In a flood the Lambro can overtop its banks, and in the lower areas near the water the flood hazard varies from street to street; the report reads it from the official maps for the address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps.
