Rezzago, a hillside village in the Valassina

Between the Como and Lecco arms of the lake, in the area known as the Triangolo Lariano, the Valassina valley climbs northwards with its villages set on the slopes. Rezzago is one of the smallest: houses gathered on the hillside above six hundred metres, meadows and woods around, and nearby Asso as the place for everyday shopping and services. Como, Lecco and Erba are reached by car along the valley road.

Homes are mostly village houses in stone and render, with a few newer detached houses and some second homes. On an exposed slope, what matters is the stability of retaining walls, rainwater drainage and winter access. Winters are cold, in climate zone E, and insulation shows on the bills.

In 2023 there were 306 residents, 11 fewer than in 2011, a fall of 3.5%, slight for a mountain village. The estimated average age is 49.1, against 46.3 for the province of Como, and over-65s make up 31.0%. Foreign residents account for 2.6%. Declared incomes are slightly below the provincial average.

Earthquakes are a minor concern: all 147 municipalities in the province of Como are in seismic zone 4, the lowest level in the Civil Protection classification, and expected ground acceleration in the built-up area is about 0.046 g. The useful checks are the roof, damp and the building's systems.

For sloping plots, the report for the address reads the official landslide and flood maps and reaches the land parcel through the Revenue Agency's cadastral maps.

Overview

Rezzago is a municipality in the province of Como, in Lombardia. At the end of 2023 it had 306 residents, among the smallest in the province (133 of 147).

Earthquakes

For Italy's Civil Protection Department, Rezzago is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 147 municipalities in the province are in the same zone.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
