What stands out

What we found in La Oliva

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

1

352 homes in a flood zone

352 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 311 of them are in the 100-year area.

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.

From 82 to 110 tropical nights a year

82→110 nights

In a typical building in La Oliva, nights when the temperature stays at or above 20 °C would rise from 82 a year (1991-2020) to about 110 by 2050. For this reason, 98 % of homes would be at a high or very high level.

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 3 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.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

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.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
