Why it was refused

  1. The site lies within Flood Zone 2 and within areas at risk of surface water and fluvial flooding in a 1 in 100 year event (+17% climate change allowance). The submitted Flood Risk Assessment fails to demonstrate that the development would be safe for its lifetime, as it does not satisfactorily demonstrate finished floor levels with the required freeboard for any ground-floor sleeping accommodation, fails to provide a Flood Management/Evacuation Plan showing a Very Low Hazard evacuation route, and does not secure appropriate flood resistant and resilient measures. The proposal is therefore contrary to Section 14 of the National Planning Policy Framework; Policies SI12 and SI13 of the London Plan (2021); Policy CP28 of the Core Strategy (2010); and Policies DMD59, DMD60 and DMD61 of the Development Management Document (2014).

From the council's decision notice.
