This Strategic Flood Risk Assessment Level 1 Report has been produced with the main end users in mind – developers, planning consultants and Local Planning Authority officers. The information below can be used to aid the reader in identifying where key information is held within this document, and what purpose the information within each section has with regards to flood risk, planning applications and developments.
|Section & Content Summary
|Flood Risk Information
(Developers / Planners)
An overview of the purpose and objectives of the SFRA. This section provides context for having a joint SFRA, with a summary of the current status of each Boroughs Local Plans.
|Planning and Policy Planning and Policy Framework
An overview of the relevant national, regional, and sub-regional policies relating to flood risk and associated requirements. An overview of each Boroughs key local policies is included.
|Sources and Assessment of Flood Risk
An overview of the flood risk from all sources across the study area, including climate change implications where this information is available. This section introduces the West London SFRA interactive map which depicts the various flood risks across the study area.
|Flood Risk Assessment Guidance
Common guidance for developers undertaking Flood Risk Assessments (FRA) for proposed development sites within any of the six boroughs. Borough-specific guidance is included where any key differences exist. This section explains the Sequential Test and Exception Test and defines the boroughs' method for the split of Flood Zone 3, including the Functional Floodplain.
A set of recommended site-specific and strategic policies. These recommendations are based on the findings of this SFRA, which the Boroughs are advised to incorporate into future versions of their Local Plans and/or associated guidance documents. An overview of the potential impact that future growth could have on flood risk across the study area is provided. Any opportunities for improved strategic flood risk management methods, including possible funding mechanisms, to assist with Boroughs growth delivery requirements are also highlighted.
|Review and Next Steps
A summary of the proposed update schedule for the SFRA (the technical content and the mapping). Recommendations for the need to conduct a Level 2 SFRA are also included based upon the findings of flood risk screening assessments of borough site allocations (included in Appendix A).
