What stands out

What we found in Les Valls de Valira

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

35 homes in a flood zone

35 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 23 of them are in the 100-year area. Next to riu Valira, 35 homes are inside the flood zone, less than 100 m from the watercourse.

According to the Ministry’s studies, this is an annual probability of 0,2 % (500 years) or 1 % (100 years), not “once every 500 years”: it can happen two years in a row. Small gullies are not always mapped.

555 homes at very high wildfire risk

773 buildings

These are 773 buildings right next to vegetation that can burn. Of these, one is a block of flats with 27 homes, where evacuation is harder.

  • Avinguda de Calvinyà: 27

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

3

Torrent de Leucata: 36 homes less than 50 m away, with no official map

36 homes

Along Torrent de Leucata (0,7 km within the municipality, dry most of the year) there is no official mapped flood zone, but there are 36 homes less than 50 m from the watercourse.

Having no official map does not mean it cannot overflow: watercourses that are dry most of the year are the ones that cause the most surprises in a storm.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
