What stands out

What we found in Sant Pol de Mar

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

1

1.120 homes at very high wildfire risk

670 buildings

These are 670 buildings right next to vegetation that can burn. Of these, 9 are blocks of flats with 289 homes, where evacuation is harder.

  • Carrer del Morer: 54
  • Carrer de Ponent: 48
  • Carrer Herois de la Fragata Numància: 40
  • Carrer Maresme: 38

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

From 33 to 73 tropical nights a year

33→73 nights

In a typical building in Sant Pol de Mar, nights when the temperature stays at or above 20 °C would rise from 33 a year (1991-2020) to about 73 by 2050. For this reason, 100 % of homes would be at a high or very high level.

174 homes in a flood zone

174 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 161 of them are in the 100-year area. Next to Riera de Sant Pol, 70 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.

Torrent del Morer: 100 homes less than 50 m away, with no official map

100 homes

Along Torrent del Morer (3,0 km within the municipality, dry most of the year) there is no official mapped flood zone, but there are 100 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.

5

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

2 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.

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.
  • 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

  • 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.
