What stands out

What we found in Xinzo de Limia

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

1

3.373 homes in a flood zone

3.373 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 2.691 of them are in the 100-year area. Next to Río Limia, 193 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.

Where there are fewer trees, 3,9 °C hotter

3,9 °C

Around homes with less than 2 % tree cover, the surface in summer is 0,5 °C above the median for Xinzo de Limia; with more than 40 % tree cover, 3,4 °C below. 338 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

1.629 homes at very high wildfire risk

2.009 buildings

These are 2.009 buildings right next to vegetation that can burn. Almost all are houses (2.003), on the edges of the town and in housing estates.

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

4 schools, care homes or health centres in a flood zone

4 facilities

They are in the official 500-year flood zone or in a preferential flow zone. They are the first to review in an emergency plan: who is inside, how to get out and whether they use the ground floor.

4 schools in heat islands

4 of 4

Schools whose surroundings are at least 1 °C hotter than the municipal median in summer. They are the first candidates for shade and tree-lined playgrounds.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Shade and trees in the playgrounds of the 4 schools with the hottest surroundings.
  • 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.
  • Emergency self-protection plans in the schools, care homes and health centres that are in a flood zone.
  • 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.
