Why it was refused

  1. The proposed development has failed to demonstrate that it would be safe from flooding for its lifetime without increasing flood risk elsewhere. In particular, insufficient evidence has been provided to demonstrate that finished floor levels would be set above the 1 in 100 year fluvial flood level including climate change allowances, or that the loss of floodplain storage would be fully compensated on a level for level and volume for volume basis. The proposal is therefore contrary to the National Planning Policy Framework, London Plan Policies SI12 and SI13, Core Strategy Policy CP28, Policies DMD59, DMD61 and DMD62 of the Development Management Document, and the New Enfield Local Plan 2041 Level 1 Strategic Flood Risk Assessment (2021).

From the council's decision notice.
