Flooding
The Environment Agency issues flood warnings to those felt to be at risk of fluvial (i.e. flooding from rivers and brooks) or tidal flooding. These warnings are telephoned directly to individual properties using the Automatic Voice Messaging System (AVM). The same warning will also be passed to the Emergency Services, Local Authorities, local radio, media and other utilities.
Residents can obtain up to date flooding information on the Floodline 0845 9881188 or via the Environment Agency's flood pages. Information on the website is updated every 15 minutes.
There are three levels of alert as follows:

More information
Flood warnings are also issued on ITV Teletext (page 154), BBC Ceefax (page 419) and on LBC News Radio (1152 AM or 97.3 FM).
Using historical flood data the Environment Agency have produced maps that show Flood Zones within the Borough. Many of these zones now benefit from flood defenses such as the Thames Barrier, raised embankments, weirs and sluices. You can use the Council's Geographical Information System (GIS) to see if your property falls within one of the Environment Agency Flood Zones.
