What stands out

What we found in Castelló de la Plana

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

1

3.293 homes in a flood zone

3.293 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 1.566 of them are in the 100-year area. Next to Riu Sec, 44 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.

9.273 homes less than 2 m above sea level

9.273 homes

That is 10 % of homes. The extreme sea level in a 100-year storm reaches 0,94 m today and 1,19 m by 2050.

Ground elevation at the building (IGN digital terrain model). Being low-lying does not mean it will flood: that depends on the beach, sea defences and drainage.

3

1.426 homes at very high wildfire risk

3.085 buildings

These are 3.085 buildings right next to vegetation that can burn. Of these, 3 are blocks of flats with 104 homes, where evacuation is harder.

  • Quadra de Velluter: 48
  • Avinguda de l'Alcora: 32
  • Carrer de la Serra d'Ares: 24

From 61 to 94 tropical nights a year

61→94 nights

In a typical building in Castelló de la Plana, nights when the temperature stays at or above 20 °C would rise from 61 a year (1991-2020) to about 94 by 2050. For this reason, 100 % of homes would be at a high or very high level.

16 schools in heat islands

16 of 66

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

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • Shade and trees in the playgrounds of the 16 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.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • 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.
