Infilling within undefended coastal flood plain as flood mitigation
Development involving infilling or raising land within the undefended coastal flood plain may be acceptable as a flood mitigation measure, provided it addresses freeboard requirements and safe access and egress to the site.
As indicated in paragraph 6.20, infilling within the undefended coastal flood plain will be considered as an acceptable flood mitigation measure as the loss of storage area will have a negligible effect on the extent of the coastal flood plain. However, development relying on infilling or raising of land will need to address other factors such as a suitable freeboard and safe access and egress to the site which may limit sites to those areas of lower risk close to the extremities of the flood plain.
