Strategic Flood Risk Assessment

Level 1

In December 2007 Gloucestershire County Council, in partnership with the six district authorities, commissioned Halcrow to produce a Level 1 Strategic Flood Risk Assessment (SFRA), as recommended by Planning Policy Statement 25 (PPS25).  The Level 1 SFRA covers the geographical areas of each of the authorities involved.

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 reports and maps are provided on the Gloucestershire County Council SFRA webpages|.

Level 2

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.
