Coastal flooding

Portsmouth may be susceptible to coastal flooding, but it is relatively easy to predict. If your home or business is at risk of flooding, you should register for flood alerts. These can be received by phone, email or text message. The service is free.

When the Environment Agency warns of tidal flood, the council deploys floodgates and flood boards in Old Portsmouth. You can find more information on the council’s approach to coastal flooding. Portsmouth City Council is also a member of the Eastern Solent Coastal Partnership.

Gov.uk also manages the risk of floods and coastal change.
