Strategic flood risk assessment

Home > Archive > Evidence base > Strategic flood risk assessment

The aim of the SFRA Level 1 is to map all forms of flood risk and use this as an evidence base to locate new development primarily in low flood risk areas (Zone 1).  Areas of 'low' (Zone 1), 'medium' (Zone 2) and 'high' (Zone 3) risk are mapped using data from a variety of sources, including the Environment Agency (Midlands and Thames regions), Gloucestershire Highways, Severn Trent, British Waterways and the district councils.

Further information and links to SFRA Level 1 reports and maps are provided individually by Cheltenham Borough Council, Gloucester City Council and Tewkesbury Borough Council.

A Level 2 Strategic Flood Risk Assessment was commissioned by the Joint Core Strategy authorities in April 2010 and published in October 2011. This provides a more detailed assessment of areas which have been identified as potential development locations and it uses the information from SFRA Level 1 to determine which areas require a further assessment of flood risk.
