Summary

​The Jersey Strategic Flood Risk Assessment (SFRA) provides an island-wide assessment of the risks associated with flooding from all sources, including the effects of climate change. The SFRA also provides guidance on the mitigation of flooding and identifies potential opportunities to reduce flooding. 

The SFRA identifies methods to deliver strategic policies, which will support long-term flood risk management in Jersey. Through this, the SFRA will support current policy in Jersey including the Common Strategic Policy (2018 to 22), the Government Plan (2020 to 23) and Future Jersey (2017 to 2037), the Island’s 20-year community vision. 

The SFRA will also feed into the Island Plan review process, forming part of the baseline evidence for flood risk and climate change. 

The aims of the SFRA for Jersey are as follows: 

  • identify the risk of flooding from all sources;
  • outline the potential cumulative impact that development or changing land use would have on the risk of flooding
  • identify the potential effect of climate change on flood risk
  • identify potential opportunities to reduce the causes and impacts of flooding
  • develop a flood risk framework and supporting policy recommendations for consideration in the Island Plan review
  • provide information on methods to manage and mitigate flood risk
  • provide guidance on producing site specific flood risk assessments
