Climate Central flood map

[Scrambledup]

There is a flood map that was put out by climatecentral.org a few years ago showing that large swathes of London are projected to be regularly under water by 2030 (due to rising sea levels). I’m looking for a property and wondering whether I need to worry about if it’s in the red zone in that map. The map doesn’t seem always to correlate with info on the Environment Agency listing for a property, where e.g. a property in the red zone on the Climate Central map is low risk for flooding from rivers and seas on the Environment Agency website (but e.g. medium risk for surface water flooding). It makes no sense to me. Does anyone know more about this?

TBH I would go with the EA mapping, and in London proceed with extreme caution if surface water flooding is even a low probability.

River flooding is well understood I think. Surface water flooding (flash floods after heavy rainfall, blocked sewers etc) is less well understood and due to Thames Water and other utility companies' lack of maintenance its impacts have become unpredictable and potentially devastating in recent years.

@redspottedmug that’s helpful, thank you. You’re saying then that if a London property was medium risk on EA website for surface water flooding you would avoid? And that you’d only consider properties that are low or very low for surface water flooding?

Personally I would avoid , yes.

Google recent London flash flood events and you will see the relationship with intense torrential rainfall. It can be very localised and therefore not easy to predict.

Lots of areas have 'combined' sewers which means if the rainfall overloads the sewage system, it causes dirty wastewater (sewage) to also flood. Ugh.

@redspottedmug yes yes I see what you’re saying. Thanks for the input.
