Polla, the northern gateway to the Vallo di Diano
Coming from the north on the A2 motorway, you enter the Vallo di Diano at Polla, which has its own junction. The old town climbs the mountainside, while the newer part spreads out towards the plain crossed by the Tanagro, the river that leaves the valley just to the north through the gorges towards Pertosa and its show caves. Polla is home to the hospital that serves much of the Vallo.
For buyers, the two halves of the town are very different. Up the hill there are alleys, steps and stone houses built against one another, often with little parking. Down below are small blocks of flats and detached houses, easier to live in but closer to the river and the drainage channels of the plain. The floor of the Vallo di Diano was marshland for a long time before it was drained.
Istat, the national statistics office, counts 5,098 residents in 2023, down 4.3% on 2011. The average age is 45.5, against 45.2 in the province of Salerno; over-65s make up 24.4% against 22.7% provincially. Foreign residents account for 7.7%.
Earthquakes come first. The Civil Protection Department places Polla in seismic zone 1, one of 18 municipalities in the province of Salerno in this zone, with an expected ground acceleration of about 0.218 g. The Vallo di Diano has been hit by destructive earthquakes, and many houses in the old town have been repaired or strengthened over time: before buying, ask for the plans of that work, the sign-off certificates and any grant paperwork.
Flood hazard on the plain and landslide hazard on the slopes vary from one street to the next, and the report checks both by address. The Revenue Agency publishes the cadastral maps, so the report reaches the land parcel.

For anyone buying in Polla, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

Official databases list one contaminated site, or site still under investigation, in Polla, and one more has been cleaned up or closed. The report tells you whether one is close to the address.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Polla: the report checks the address against the ISPRA maps.
House prices
The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 37 inhabited census areas in Polla. Half of the residents live in areas scoring 60 or more.
