A SFRA is a live document which is to be used to assist in allocating sites for future development and general decision making. It is essential that the data contained within the SFRA is as up to date as possible to ensure that decisions are made on the best information available. Events that may trigger review and update are summarised below:
- Changes to the NPPF and associated Flood Risk and Coastal Change PPG which form the basis of the SFRA.
- Updates to any of the overarching legislation which may alter the responsibilities of the Boroughs – including the new London Plan and RFRA documents, which are both currently undergoing consultation and are expected to be finalised in late 2019.
- Changes to the flood risk information. There is a need to ensure developers and the LPA are provided with the best available information.
- Developments in flood risk knowledge. There is a need to ensure that site-specific FRAs are informed by the most up-to-date information and planning decisions are made on the best available data.
- Significant updates of baseline flood risk information (such as a major update to the Risk of Flooding form Surface Water map or Flood Map for Planning) or following a major flooding event within the sub-region.
