Download the Preliminary Flood Risk Assessment 

Portsmouth’s Preliminary Flood Risk Assessment (PFRA) was completed in June 2011 as directed by the Flood Risk Regulations 2009. This assessment is a high-level screening exercise to collect information on past historic and future potential floods. This information was then used to identify flood risk areas in the city - none were identified.

The PFRA was reviewed in 2017 and no new flood risk areas were proposed.
