Orsago, the Treviso plain towards Friuli

Orsago lies in the eastern part of the province of Treviso, on the plain between Conegliano and Sacile, towards the border with Friuli, with hills rising towards the Cansiglio to the north. The town is crossed by the Venice to Udine railway, which has a stop here.

If you work in Conegliano, Sacile or Pordenone, you will find detached houses, newer homes and small blocks of flats, often with gardens, and a small craft and industrial area. Along the through roads traffic is a factor, while the side streets are quieter. Average declared incomes are below the Treviso average.

In 2023 there were 3,799 residents, 3.0% fewer than in 2011 according to Istat, the national statistics office. The estimated average age is 47.0, against 46.0 in the province, over-65s make up 25.9% and foreign residents 10.1%.

The seismic figure should not be underestimated. The foothills between Treviso and Pordenone are among the most exposed areas in northern Italy, and the province of Treviso has 72 municipalities in zone 2 of the Civil Protection Department's scale. Orsago is one of them, with an expected ground acceleration of about 0.226 g. For a house from the 1960s or 1970s, have the structure assessed before renovating and ask about the tax incentives for earthquake strengthening.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report traces an address back to its plot. With streams running down from the hills onto the plain, it also checks flood maps at that exact point.
