Strategic flood risk assessment (SFRA) 2024

The council published an updated Level 1 SFRA in April 2024. The updated SFRA was prepared by consultants AECOM and replaces the previous 2019 version.

The Level 1 SFRA provides an overview of flood risk from all sources, for example, rivers, surface water, groundwater, sewers and reservoirs, across the borough. It also provides guidance to assist applicants in preparing site specific Flood Risk Assessments (FRAs) in support of planning applications.

The 2024 SFRA report and associated mapping can be accessed below. It is a 'living' document and will be updated to reflect any changes to flood mapping issued by other organisations, for example the Environment Agency.
