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 sign up for flood alerts on GOV.UK. 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 Coastal Partners.
The government also manages the risk of floods and coastal change – GOV.UK.
