Dervio, on the eastern shore of Lake Como
Dervio sits on the small delta of the Varrone stream, on the eastern shore of Lake Como between Bellano and Colico. Behind the village the mountain rises steeply towards the Legnoncino and the Valvarrone, and on the lake the headland of Corenno Plinio, a medieval hamlet that belongs to the municipality, reaches out into the water. Lecco is to the south, about half an hour by road.
For anyone working elsewhere, the strong point is the railway along the shore, towards Lecco and Milan in one direction and the Valtellina in the other, with a station in the village. The Valtellina expressway runs higher up, mostly in tunnels. Homes vary a lot: the flat, practical land of the delta, the old core of Corenno, and houses on the hillside, often with lake views but steep access. Part of the housing stock is second homes and holiday flats.
Istat, the Italian national statistics office, counts 2,559 residents in 2023, down 4.6% on 2011. The population is on the older side: the average age is 49.5, against 46.6 in the province of Lecco, and 29.7% are over 65. Foreign residents make up 7.6%.
Earthquake risk is low. Dervio is in seismic zone 4, like 19 other municipalities in the province, with an expected ground acceleration of 0.042 g. In older houses the roof, damp in walls close to the lake and the systems matter more.
Between stream, lake and slopes, ground conditions change from one street to the next. The report reads the official landslide and flood maps for the exact address and, using the Revenue Agency (Agenzia delle Entrate) cadastre, traces it back to the land parcel.
