5. Strategic Flood Risk Assessment (SFRA)

The front cover of the Strategic Flood Risk Assessment ReportThe Strategic Flood Risk Assessment (SFRA) is a high-level assessment of the flood risk in Bath and North East Somerset. It has been prepared on behalf of the Council by expert consultants.  It supersedes existing data on flood risk including the indicative floodplain used in the Bath and North East Somerset Local Plan.

The SFRA provides essential information for the allocation of land for development and the control of development in order to limit flood risk to people and property where possible and manage it elsewhere. The SFRA will provide the information needed to apply the sequential risk-based approach required in national Planning Policy Statement 25.

Bath and North East Somerset Council has completed a Level 1 and Level 2 Strategic Flood Risk Assessment for the district. Details on each of the assessments, including reports and maps are available on this page. Click here for an explaination on the levels of SFRA.

Due to the size and technical nature of the maps in each of the reports not all of the maps are available on our website. However copies of the SFRA including all maps are available for inspection on Mondays to Thursdays 9.00 am to 5.00 pm and Fridays 9.00 am to 4.30 pm at the following offices:

  • The One Stop Shop, 3-4 Manvers Street, Bath, BA1 1JQ;
  • The Hollies, Midsomer Norton, Bath, BA3 2DP; and
  • Riverside, Temple Street, Keynsham, Bristol, BS31 1LA

Caution: The SFRA are live documents which are intended to be updated as new information and guidance becomes available. The outcomes and conclusions of the SFRA may not be valid in the event of future changes. It is the responsibility of the user to ensure they are using the best available information when making a land planning decision.

5.1 SFRA - Background information

Planning Policy Statement 25 (PPS25) sets out Government policy on development and flood risk. It's aims are to ensure that flood risk is taken into account at all stages in the planning process to avoid inappropriate development in areas at risk of flooding, and to direct development away from areas of highest risk. Where new development is, exceptionally, necessary in such areas, policy aims to make it safe, without increasing flood risk elsewhere, and, where possible, reducing flood risk overall.

In order to achieve this the Council is required to apply the Sequential Test at all stages of planning. The aim of the Sequential Test is to steer new development to areas with the lowest probability of flooding. The SFRA refines information on probability of flooding, taking other sources of flooding and the impacts of climate change into account.

Useful documents:

  • Planning Policy Statement 25 Development and Flood Risk
  • Development and Flood Risk: Consultation on a Practice Guide Companion to PPS25

5.3 SFRA Level 2 (July 2009) - Background Information

The SFRA level 2 report builds upon all of the technical information and methods used in the Level 1 assessment of flood risk across the study area. The report is intentionally partitioned from the SFRA Level 1, as it does not repeat guidance contained within the SFRA Level 1. The need for a Level 2 SFRA is primarily driven by regeneration and new development requirements outlined in the B&NES Local Plan and the draft South West Regional Spatial Strategy.  Level 2 SFRA has been undertaken to provide greater understanding of the factors contributing to the probability of flooding in the potential development areas, provide guidance for Local Development Framework policy.

The Level 2 Assessment for the district is divided into 3 parts. These are Bath, Keynsham and Midsomer Norton and Radstock. The reports for each of the 3 place base assessments are available to view on this webpage along with a selecton of the key maps supporting the SFRA.
