Story summary

In a recent high court decision, houses can be built on floodplains even if they fail crucial safety tests. This ruling clears the way for 190 new homes to be constructed in north Somerset, despite the site being classified as "flood zone 3a," indicating very high risk of flooding. The judgment has alarmed ministers and experts, who are pushing for a change in national planning laws to prevent similar developments across England and Wales. Tessa Munt, chair of the Flooding and Flooded Communities APPG, is meeting with Matthew Pennycook, the housing and planning minister, to discuss amending the National Planning Policy Framework (NPPF). Munt described this decision as a "dangerous exploitation" of planning loopholes that could lead to similar speculative developments nationwide.
