Strategic Flood Risk Assessment (SFRA)

A Strategic Flood Risk Assessment (SFRA) assesses the flood risk across the district. Consultants JBA were commissioned to carry out an SFRA to support the Local Plan Review and the Minerals and Waste Local Plan.

Level 1 SFRA (2022)

The SFRA (2022) [3MB]  provides an overview of flood risk across West Berkshire. 

It contains the following appendices:

• Appendix A1 Local Plan Review Site Screening [568KB]
• Appendix A2 - Minerals and Waste Site Screening [515KB]
• Appendix B - Sewer Flooding Records [74KB]
• Appendix C - Flood History [35KB]
• Appendix D - Watercourse Catchments [18MB]
• Appendix E - Recorded Flood Outline [22MB]
• Appendix F - Flood Zones [22MB]
• Appendix G - Flood Defences, Assets and Structures [21MB]
• Appendix H - Flood Warning Areas [23MB]
• Appendix I - Flood Zone 3 + Climate Change [24MB]
• Appendix J - Risk of Flooding from Surface Water [24MB]
• Appendix K - Groundwater Emergence Mapping (Jacobs) [22MB]
• Appendix L - Groundwater FLood Mapping (JBA) [24MB]
• Appendix M - Reservoir Flood Risk [22MB]
• Appendix N: Location Map [31MB]
• Appendix O: Surface Water Flood Risk Climate Change (1 in 30 Year) [42MB]
• Appendix P: Surface Water Flood Risk Climate Change (1 in 100 Year) [44MB]

Level 1 SFRA Addendum - Cumulative Impacts Assessment (2020)

Following the completion of the Level 1 SFRA, changes were made to the National Planning Policy Framework. The changes now require SFRAs to consider the cumulative impact of development on flood risk within a catchment.

As an addendum to the Level 1 SFRA, JBA consulting produced a  Cumulative Impacts Assessment [1MB] .
 

Level 2 SFRA (2021)

The Level 2 SFRA [846KB]  looks at the flood risk to specific sites to supplement the information within the Level 1 assessment. A Level 2 SFRA is not required to support the Minerals and Waste Local Plan.

There are three appendices to the Level 2 SFRA:

• Appendix A - Updated Site Screening [157KB]
• Appendix B - Site Summary Sheets [2MB]  (updated 2022 to take account of peak rainfall allowances that were published by the the Environment Agency in May 2022)
• Appendix C - Site Maps [27MB]

A Level 2 SFRA of the North East Thatcham strategic site allocation was prepared as part of work on the Core Strategic Development Plan Document in 2009, and it can be viewed online [4MB] .
